vanemeth Posted January 10, 2007 Report Share Posted January 10, 2007 Was thinking bout making a gang saw for slotting fretboards. Could take a 3' threaded rod and 22 - .023 slitting blades found for roughly $5 eack on the internet. A couple of block bearings on each end of the rod ,and the blades spaced accordingly on the rod. Then with a pulley and motor on the end on a makeshift table/stand, rig up a one pass fretboard slotting saw. Bad idea, good idea, just plain stupid...input please.

biliousfrog Posted January 10, 2007 Report Share Posted January 10, 2007 to my noob-like mind that sounds great...I guess the theory is ok, it's just how well it can be built. Quote Link to comment Share on other sites More sharing options...
bvalentine Posted January 10, 2007 Report Share Posted January 10, 2007 Of course it is possible... but my opinion, unless you're trying to crank out 10 guitars a day... why bother. Seems you'd be more accurate by hand. Here is Gibson's: Quote Link to comment Share on other sites More sharing options...

Definitely keep us in the loop - I'd love to see what you come up with. Regards, Rob Quote Link to comment Share on other sites More sharing options...
Prostheta Posted January 10, 2007 Report Share Posted January 10, 2007 I think the biggest challenge would be keeping each of the blades true and not running out slightly. Very difficult if you're proposing 22 blades spaced to around 0.1mm each. I would imagine that a machine shop millling a set of 21 accurately made mid-blade shims plus two end spacers, and two or three rods to go through the spacers, blades and end caps with tightening nuts would be a bluffers approach. Kind of like a diminishing stack. Quote Link to comment Share on other sites More sharing options...
vanemeth Posted January 10, 2007 Author Report Share Posted January 10, 2007 I do have one question maybe you guys could help me out. Regarding the slitting saw blades, I have read that some makers say you can use these and other who say you absolutely cannot. What is the deal? I have ordered one recently (have not gotten it yet and it was only five dollars) to see if I can use it, but has anyone given it a go and what were your results?

jay5 Posted January 11, 2007 Report Share Posted January 11, 2007 I think your design sounds doable. The blades you are talking about should work also. I would imagine that some VERY careful setup would be required but theyre is no reason why you shouldnt be able to mfg a usable rig. Quote Link to comment Share on other sites More sharing options...

I have ordered one recently (have not gotten it yet and it was only five dollars) to see if I can use it, but has anyone given it a go and what were your results? the reason you see that is because people are trying to use them on there table saw. for that Id just get the stewmac blade, much more stable. if you've ever watched the "how its made" series on discovery youd see Godins uses a saw EXACTLY like what your talking about. but honestly, if your going to be making less then 10 a day, a fretsaw and Jig work just as fast. it took me 5 minutes to slot 3 boards. Using just the stewmac blade, and my jig. Quote Link to comment Share on other sites More sharing options...
soapbarstrat Posted January 12, 2007 Report Share Posted January 12, 2007 I have an old Jackson Guitar Co. catalog with a small photo of a 22 blade set-up like you are talking about. They have it so the neck swings, and it cuts the fret slots to the same depth on the radius. Quote Link to comment Share on other sites More sharing options...
jay5 Posted January 12, 2007 Report Share Posted January 12, 2007 but honestly, if your going to be making less then 10 a day, a fretsaw and Jig work just as fast. 10 a day!? We do 6-8 a week at work and I would LOVE to have a gang saw. Hell, it takes me 3-4 minutes a piece to do them on the tablesaw, I cant imagine that I could do 3 boards in 5 minutes by hand. I guess if you are doing one or two at a time you might save some setup time by doing it by hand. The slotting blades in a setup like you are proposing would work just fine. The LMI blade is just a 6" HSS slotting blade. now get to work! Quote Link to comment Share on other sites More sharing options...

I still call it a fret saw, sorry. its the "fret slotting blade" but thats all I used that table for. and my shooter board is long enough to do multiple boards.

postal Posted January 13, 2007 Report Share Posted January 13, 2007 Go to "MIMF" tools and jigs. There's an active discussion on this right now, and I dont feel like typing twice. But I can answer questions you may have after reading that thread. Quote Link to comment Share on other sites More sharing options...
