  1. Wood Selection (or usage)

    I don't think that is a bad idea at all. Sandwich the maple between two pieces of stable mahogany then resaw down the middle of the maple.
  2. 10w Amp wiring help - Desperate!!

    The wire is either a centre tap for the secondary of the transformer or a voltage tap for a different voltage output. Very difficult to say without a circuit diagram. If its a centre tap it would be connected to ground. However if you don't understand mains wiring take it to someone who does. Messing with mains side of amplifiers can KILL you if you don't know what you are doing!!!!!!!
  3. Fretting Saw

    I had my own blade made up to fit my radial arm saw. I went to my tool sharpeners who took a thin blade they had lying around about to be thrown out and ground it to the kerf width of the stewmac blade. It cost me about $10! It helps having a long standing relationship with them I suppose (and my father before me).
  4. I would still go with making a template. Making a mistake on a piece of MDF is easily rectified. Making a mistake on your precious piece of wood is another thing. You don't have to use a router but can use the template with a sanding drum provided you have or can rig up a suitable follower.
  5. Help with wiring

    It is most likely a mistake in your wiring. Without knowing the specifications of the switch you are using it is very difficult to know if the diagram and the switch illustrated correspond. Having said that these pictorial diagrams, I find, are almost impossible to trouble shoot with. Far better is a proper schematic of the circuit.
  6. Wilkinson Zebra pickup wire colours

    Don't solder on to the back of potentiometers! It is asking for trouble! Chances are you will overheat and damage the pot or get a cold dry joint or both! Some pots have a solder tag connected to the case for this purpose. If you cant find these buy some solder tags which fit over the shaft of the pot and bolt up against the body of the pot. I don't know where this solder on the back of the pot came from. It is BAD practice. If we had of done this in our electronics training practicals we would have been failed outright! It probably came from some notorious penny pincher trying to save a few cents!
  7. Veneers without the tears!

    Have you tried this on an Archtop/Carved top? I'm busy restoring an ES330 no name brand archtop style guitar which needs a re-veneering all round (Top,back and sides) Any Advice?
  8. I've never done a whole fret board but I have filled a few slots where in a moment of inattention a slot got cut in the wrong place. I found that using rosewood veneer and cutting slices with the grain vertical NOT across the board (ie cut your strips off the end of the veneer) ,gluing in with CA then sanding while the glue was still liquid and working the dust into the cracks made a close to invisible repair. Running the veneer with the grain running across the board shows discontinuity in the grain of the fret board. However in your case I presume you are going to re cut with the identical scale length so most of the veneer will be cut out again and the fret itself will cover the cut so you could use any wood really but matching the wood species would probably be better.
  9. Partially Filling Tremolo Block Routing

    Chooch Really? The only definition I could find means "idiot" "fool" "Stupid person" and the verb would mean to do something stupid!
  10. You can try asking Ken McKay at www.upnorthstrings.com he was making them and also had some tutorials on using them to build laminated archtops. Also try http://acme-archtops.com/ and http://www.pacinfo.com/~sholst/laminatedplates.htm
  11. Dreadnought Acoustic

    Well here its actually raining. The sun has taken up permanent residence and has been beating down relentlessly for months with no respite. We have only seen a break over the last 10 days! Now of course with everything so dry the rain is causing havoc washing away topsoil causing potholes in roads etc. Great guitar and especially your method of gluing the bindings. We used to use a similar method when applying veneer sheets to foam cores for making radio glider wings. Have you looked at Trevor Gores neck joint method? It is a double tenon bolted in both planes.
  12. How To Make A Vintage Compression Truss Rod

    Great tutorial. However one comment: having built truss rods with 6mm Rod: They are just a bit to chunky. 5mm I find is far better using M5 taps and dies. This is comparable to using 3/16" rod and 10/32 taps and dies. 3/16 rod being only slightly thinner than 5mm (about 0.2 of a millimetre)
  13. In terms of string tension an acoustic archtop there is no exception. Acoustic archtops perform better when there is an optimum amount of down force on the arched sound board. This is directly proportional to the angle of the strings over the bridge. Given the tailpiece height at the same as the bridge the force is all in line with the strings. Lowering the tailpiece (or raising the bridge) will create a vector of the force vertically into the sound board giving the required down pressure on the top.
