Making the Kerfing

It's been about a month since my last post. We've had a lot of company this last month, plus I've been doing lot's of other summer-time stuff and honey-dos. I should have just purchased Kerfing but once again I just had to make it from scratch. (at least on this first guitar).

Started buy cutting out many of these blocks of mahogony.

Then made a mark on the saw table to line to wood up.

Just continue to line the mark up and cut.

Almost done.
All the blocks are kerfed.

Cutting the kerfing on a steep angle.

All the angles are cut.
Finished up by ripping them all down to finished size. I think I have enough kerfing to do a couple guitars. Really glad this step is done!

Kirfing Jig (a waste of time)

I based the design of this jig off from this video:

Except, I thought It would be more useful to have a wheel advance instead of a rack advance.
I did all the math and sure enough this will advance a quarter inch every click.

Once circle for advnacing the wood and the other to go between the gear and the advance.

I placed old bicycle tire rubber around the bottom circle to help grab and advance the wood.

Completed jig.
Lever moved to advance the wood.
So did it work? Yes, and no. It did work in advancing the wood, but was inconsistent when the wood block thinned out a little. I was disappointed and will most likely re-make this someday with springs to hold the wood up to the round block and I'm sure it will work perfect. I just got tired of building jigs and wanted to get back to working on the guitar.
