    Pots and bridge studs are in, I'll need to deepen the toggle area for a hair and reapply a piece of the foil, shouldn't be a problem. I didn't take the cupping of the dip in the top/washer into account, if that makes sense...otherwise, seems OK, I'll start the wiring. I'm planning a treble bleed, a 470pf/100K combo, any other suggestions? The pots are 500k. 185 by Goran P, on Flickr
  2. PRS-like project(s)

    Hi! I've got a new project, I would like to try a guitar with a vibrato unit, I did that only once, a PRS-like guitar for my brothers 18th birthday in 2002. This might become 2 guitars, but that remains to be seen. First, I pulled out a cherry board from the shed, which is over 33cm wide, so I can get 2 one-piece body blanks: 1 by Goran P, on Flickr I roughly cut 2 pieces, trying to avoid cracks on the ends of the board: 2 by Goran P, on Flickr and then, a few minutes on the neighbor's thickness planer reveals fresh surface - again cherry 3 by Goran P, on Flickr I've ordered some binding: 4 by Goran P, on Flickr This is the template I've used then - it's not a exact PRS shape, the bout is narrower, but the length is same I think. I usually don't shape the body outline with a router, fearing tearout (and the router itself ), but since it's has a vibrato unit, this is already out of my comfort zone... 5 by Goran P, on Flickr This is the unit I've ordered: 6 by Goran P, on Flickr Routed the shape after cutting roughly, and had 2 issues - the router bit into the template at 5 o'clock, and a big tearout at the tip of the horn. I can sand out the first, and hope to be able to carve out the second, perhaps with some minor surgery... 7 by Goran P, on Flickr 8 by Goran P, on Flickr Freehand routed the ledge (15mm height difference) and a rough carving line, just to get rid of some bulk. 9 by Goran P, on Flickr Started planing the top angle. around 2 degrees. It starts behind the bridge, so it's basically zero angle, angled neck guitar 10 by Goran P, on Flickr 11 by Goran P, on Flickr 12 by Goran P, on Flickr 13 by Goran P, on Flickr

    Thanks! The TR cover is plastic I bought on Ali, it was really cheap so the plastic has some slight texture, but it looks OK here It flips open, so that looked interesting. Still waiting on mini hums.

    Assembly time! My son helped (it means he has claimed the guitar), but being 8, we went trough the paint on the tip of the headstock while polishing...I guess we can live with that. The clause is that he has to take lessons 184 by Goran P, on Flickr Bridge and the wiring to follow!
  5. PRS-like project(s)

    Thanks! Yes, that's the idea, I want to set it up with a floating bridge. One thing that I can't make right now is to have a sliding nut to go with the screw that tightens it down once it's been set up. It would need a tiny rail, and that would be an overkill I might do it later with, say, 2 brass strips and some shallow routing, but that can be done on any string change if needed. Just a quick pic of cutting the slot - last time I cut twice and drilled once, and this time stacked 3 saws on the frame to get the width needed. Used 2 clips to keep them nice and tight during the cutting, worked fine. Just one cut, and it stayed pretty straight. No pic of the finished part, I just sanded it a bit and chamfered all the edges after this. This is all not machined-straight, but for the setup I've used, it's OK and functional. 178 by Goran P, on Flickr 179 by Goran P, on Flickr Regarding the design - thanks! I Think I will make it during this year, perhaps altering it a bit more to get a better thumb access. But first, I need to finish a few other things - the BillyBo sibling I've started some time ago, and a tele and a 335 commisioned by a friend. Waiting!!!

    OK, the claw, v.2 I've cut a new blank, marked all the lines and holes and drilled trough with a 2 mm bit. It seems that the brass cuts much quicker on small diameters, and enlarging them gradually is fairly easy. The drill was set at almost minimum speed. I tried to drill 2 depth stops (6.5mm) without pre-drilling and that went very slowly for a depth of 5.5mm. The most challenging bit of work was the angled drilling, I broke a few drills as my setup obviously has a lot of play in it, and then the 7mm bit wandering, causing the rough inner surface. I decided to use slightly longer screws, but the heads had to be turned down a bit to fit into the slots. Quite some filing to do yet to square it all up and remove (most, where possible) tool marks. I'll cut the spring slot later today, and I think I have a nice idea on how to do it a little bit better than the last time. 168 by Goran P, on Flickr 169 by Goran P, on Flickr 170 by Goran P, on Flickr 171 by Goran P, on Flickr 172 by Goran P, on Flickr 173 by Goran P, on Flickr 174 by Goran P, on Flickr 175 by Goran P, on Flickr 176 by Goran P, on Flickr 177 by Goran P, on Flickr

    Thanks! Haven't had any time for the shop for a few days now, but I could squeeze in a few hours tonight. I'm looking forward to trying this out.
  8. PRS-like project(s)

    I agree, but the accessibility of the adjustments screws could be an issue, and it would be a bit more discreet in person I think. I coloured the parts for the drawing, but it would all be less pronounced when machined, and the part itself is pretty small, 20x32x10mm. I might make both to compare.
  9. PRS-like project(s)

    After some more thinking, this seems even better: claw2 by Goran P, on Flickr It could be a bit tricky to do the angled drillings, but I'll take my time and have fun Comments please, am I missing something?
  10. PRS-like project(s)

    I think I have a better version of the claw, with better access to adjustment screws. First idea was not very user friendly, and I can't assume I'll be the only one to play/adjust this guitar. claw by Goran P, on Flickr The adj.screws should have hexagonal heads, for better access between the springs, but we'll see. Perhaps not needed...I will have fun making another one ...and will use the drill press this time
  11. PRS-like project(s)

    Some more work on the claw. I might make v.2 with different layout of holes, but I think this one will be OK, if I don't break it when I drill the adjustment holes. I made 2 cuts first, then drilled trough, and finished the cut with the round file. I'm planing to have the claw screw trough to the neck when adjusted, so that the vibration transfer is maximal. 159 by Goran P, on Flickr 160 by Goran P, on Flickr 161 by Goran P, on Flickr 162 by Goran P, on Flickr 163 by Goran P, on Flickr 164 by Goran P, on Flickr 165 by Goran P, on Flickr It was already dark, so the pics are ...... , but I did manage to get 3 coats during the day. Scars on the back are pretty obvious, but I'll see if that bothers me enough to do something like veneering or not, probably not. All the holes and cracks were nicely filled, but the downside is that the dye cannot be applied evenly. 166 by Goran P, on Flickr 167 by Goran P, on Flickr
  12. PRS-like project(s)

    Thank you all! I don't use a thumb much at all for fretting, perhaps a F# when playing a Keith Richards-like D chord, so I don't immediately think of it. I'll probably tweak it some more, and perhaps make one during the summer. I think I have most of the parts needed already. Managed to drill the wire holes nicely for both pickups, trough the 12mm hole drilled for the jack. Ground hole from the spring claw was easy then. Exit points nice and where intended Also, finally got around to routing the ledge. I drew the shape, scored it with a marking knife and used a Dremel in the routing jig with a straight 3mm bit. Some sanding to do to clean it all up. 152 by Goran P, on Flickr 153 by Goran P, on Flickr Then I made the body of the claw - brass stock, 20x10mm. The cavity is 10mm deep so it should sit flush. Still some drilling to do. When I buy some larger stock I'll attempt the trem block too. 154 by Goran P, on Flickr 155 by Goran P, on Flickr 156 by Goran P, on Flickr 157 by Goran P, on Flickr And a nut cut, just for a pic for now. I've cut that one before, synthetic, but I'll cut a cow bone one too. 158 by Goran P, on Flickr
  13. PRS-like project(s)

    After a lot of sanding I applied 2 coats of gold paste. Still one to go, mostly to touch up some highs spots that have popped out after the second coat and require yet more sanding.... My pickup routing template worked perfectly fine as intended. I taped it permanently to the 8mm MDF, and routed trough with a bearing equipped short bit. As I had the corners cut too sharp, MDF has four ledges in the corners, due to the difference between the acrylic corners and the bit diameter, which holds the acrylic insert perfectly fine for routing two screw pockets. So, first drilled 2 pilot holes fi12mm to 24mm depth, routed the pup cavity to 12mm depth, and routed the pockets flush with a 6.35mm straight bit. Went fine, and reasonably quick. I should drill 2 holes for pup wires before the last coat of gold (which is really durable, I've level sanded it and it's a tank. Also, dries in seconds), and route the cover ledge, which I completely forgot about in the last session. 145 by Goran P, on Flickr 146 by Goran P, on Flickr 147 by Goran P, on Flickr 148 by Goran P, on Flickr 149 by Goran P, on Flickr 150 by Goran P, on Flickr 151 by Goran P, on Flickr I have lent the fretless bass to a guitar playing friend for a while, his band is about to record their second record, and they would like it on 2 or 3 songs We joked about a guitar version of it for a while, so I used a quiet part of the day to come up with this: nove gitare1 1 by Goran P, on Flickr Any obvious mistakes in my thinking? Should balance nicely and be pretty light, but I was hoping to make it more sitting-friendly, and allow some thumb space for people who play that way.
  14. PRS-like project(s)

    Well it only gives my wife an excuse to buy more... I have a rubber mat I use, and we use the kitchen table for crafts and stuff for school and kindergarten all the time, so it's completely legal. And sanding is already unpleasant, no need to add winter cold to the experience Yes, white acrylic sheet, 5mm thick. The process I mentioned I found on YT, it was a part of a relicing/ageing process on a LP. Not my thing, I make mine pre-dinged and scratched but the work itself was nice to watch, great attention to details. Search Dr.Nitro, if it's OK to mention it here? The theory is that the acetone softens the surface, alcohol slows the softening, and the dye can mix itself in the softened surface and stay there. Works fine on YT, I would like to try it myself.
  15. PRS-like project(s)

    Nothing much to show for now, just this one pic of the pup rings I had laser cut. I also made the routing template in the same session. It has the ring part for routing the actual cavity and the insert part for routing the two dips for the adjustment screws. I think I will be able to get away with routing basic pup cavities to 10-12mm depth, leaving about 12-14mm of the tenon intact. So, I have to rout the pup cavities and the cover recess on the back. In the meanwhile, I've been sanding (on the kitchen table in the evenings), filling cracks and wormholes, resanding, refilling etc. It's looking better and better, but still a lot of sanding ahead until I can dye the back, sides and the neck some sort of light walnut/mahogany brown. The pup rings are really white, but I won't do anything about that until assembly time. I would like to see how will they look on rubbed gold top as they are. If needed, I found a really nice method using yellow dye, acetone and alcohol to dip parts in and then repolish. New tablecloth 144 by Goran P, on Flickr
  16. PRS-like project(s)

    Yet another routing session last night. Managed to clean the electronics cavity route and did some more CA saturation/filling in spots, more to go. I managed to route out the spring cavity using an improvised jig, I hope this will work as intended. The claw block cavity is 10mm deep, and the rest is 9mm. It might seem silly, but I want as much wood around that tenon as possible. Still to rout is the electronics cover recess and the pups, I'll get the jigs laser cut from plexi along with the pup rings... 139 by Goran P, on Flickr 140 by Goran P, on Flickr 141 by Goran P, on Flickr 142 by Goran P, on Flickr 143 by Goran P, on Flickr
  17. PRS-like project(s)

    Yes, it will be exposed as this is going to be a goldtop. I'm planning to saturate the glue lines with epoxy, or to inlay two lines of MOP between pickups to prevent the lines to show after a while. I should have enough small MOP offcuts, but I'm still not sure how it would look - goldtop + MOP? The neck, sides and the back will be dyed light brown.
  18. PRS-like project(s)

    I think I have the puzzle solved, preparing to route it out. The springs require 9mm in diameter, and since I want 3 only, I can get away with using 2 center holes on the block, and the 5th (where the arm is, with 3 center pins on the claw. That has significantly smaller footprint that the standard cavity. Routing later today I hope. Also, finalized my cardboard pup rings, and used them to draw out the prep for laser cutter. I will go with milky white, 5mm thick, and do...something to it if the color is too off Sawing these out by hand seems a bit too much, as I would probably crack something a number of times. Neck one has that extension as to avoid the cutout area of the lower horn. minihumrings by Goran P, on Flickr
  19. Stripy Double Cut With An F-Hole

    Nice clean work as usual! Hope the frets won't give you any more trouble. Could you perhaps explain a bit more your procedure for going from chiseling to smooth when carving? You probably explained it at some point, but can't remember where...
  20. PRS-like project(s)

    Yes, the crack is there since the start of this build. Didn't expand any so far luckily. I was planing to flood it with warm epoxy later on, but I took your advice and flooded it with CA from pocket side first. Put some masking tape on the other side of the crack, and will repeat from outside later. Thanks for the advice again, better safe than sorry I would also like to flood the seams with epoxy, and cover them with 2 MOP lines, I think I could have enough small pieces to put together. After the cracks, reapplied the black dye to the fretboard sides, and glued in the neck with PVA. This will stop any warping the body might attempt after routing out such a large neck pocket, which was one of my concerns. I found a really nice video on relicing with a part on aging plastic parts. I found a piece of white pickguard material, so I might experiment a little to get a more ivory/cream color. Made 2 cardboard props to help me figure out the pup locations and whether I can fit them on my piece of plastic. 135 by Goran P, on Flickr 136 by Goran P, on Flickr 137 by Goran P, on Flickr 138 by Goran P, on Flickr Next puzzle to solve is the minimum depth of the spring cavity route - the body is 41mm at it's thickest, and with tenon depth being 24mm, I would like to keep it to 10 mm, and perhaps do 3 separate routes for the springs, or one narrower route. The cover will not be recessed.
  21. PRS-like project(s)

    ...and some more work today - found my original templates, straightened a few details and first routed the top side, drilled trough, and routed from the back side. Prior to routing for the spring cavity, I want to decide on the best possible route depth. As I said, I'm thinking of replacing the claw with a brass block to add some mass. Also, that way I could make the route about 10mm deep only. If that goes well, I might attempt to replace the trem block with brass one too. I'll try to scrape together enough MOP to hide the seams before applying the gold paste. 128 by Goran P, on Flickr 129 by Goran P, on Flickr 130 by Goran P, on Flickr 131 by Goran P, on Flickr 132 by Goran P, on Flickr 133 by Goran P, on Flickr 134 by Goran P, on Flickr
  22. PRS-like project(s)

    Went well - here are some pics of last night's session: Made the neck pocket template, rough routed with a wider bit, re-routed with the template and the bit with the bearing, and the neck fits just right Clamped overnight to make sure there is no warpage. 121 by Goran P, on Flickr 122 by Goran P, on Flickr 123 by Goran P, on Flickr 124 by Goran P, on Flickr 125 by Goran P, on Flickr 126 by Goran P, on Flickr 127 by Goran P, on Flickr
  23. PRS-like project(s)

    Thanks! Well, I prefer to have one continuous surface for carving, since it involves scraping, sanding and finger planes, and a large hole like this neck pocket, extending all the way to the bridge or the pup holes could force some mistakes, like dips near their edges etc. It might not be a problem, but I feel safer this way. This top is fairly flat, so fixing the routing template with some tape should not be a big problem. Also, this is a one-piece body, so it could warp a bit. I will in fact clamp it down after routing just in case. I do my LP tops the same way, even though they have a more pronounced carve, and the pocket is much smaller. There are other approaches, but I feel safer with this one. BTW, you should definitely try to carve a top! I'll try to take a pic of my first try, semi hollow LP shaped monster Baseball bat neck, Bigsby, P90's...plays horribly, I should strip it and dress the frets, re-carve the neck etc.
  24. PRS-like project(s)

    Well, back to building! Didn't have much time to spend in the shop, and additionally, it's time for the scary part - routing a huge neck slot in the finished and unsuspecting top... I prepared a detailed plan for the slot and cut the neck to size. It will actually form one side of the vibrato route. I plan to route that after the neck has been safely glued in place, so that I can check the centerline. So, routing is next, template is drawn, my new short routing bit is ready, and I'm a bit nervous about it 120 by Goran P, on Flickr
  25. PRS-like project(s)

    Hi! Thanks a lot, it's always nice to hear that the pics (and the mistakes ) were of help! Here is some update on the neck, I have finished this stage a few days ago, but haven't touched a computer for a few days. I made a simple sanding surface to help me in the shaping the neck without dips or high spots and the results are really nice. It's in the pics. Length is roughly distance between the volute and the heel, with ends half rounded, with some 60 grit paper. After rough shaping, this made sure that its all straight. I will fine tune the profile some more while progressing trough the grits, but it's basically done. The locking tuners arrived in the mail, so I can drill the headstock, and various bits and pieces are on their way. I decided on 2 mini hums for this guitar, and since I was unable to source the cream rings for them, I will have to make them. Cream or ivory colored plastic is not that easy to find locally, so I'm looking into all kinds of options... 117 by Goran P, on Flickr 118 by Goran P, on Flickr 119 by Goran P, on Flickr
