Re: simple veneer type rosette making

I set up another router to rout the area where the veneer will go. Veneer being rather thin, the bit is set accordingly and the rout still leaves the purfling grooves intact. I then use spray shellac to lightly seal the rosette area. I set and tack in place the purfling strips with CA glue

Re: simple veneer type rosette making

After the veneer ring is cut I use alcohol or lacquer thinner to release it from the substrate and set it aside to dry (which only takes a few minutes). I then reset the router to cut the sound hole groove. I cut most of the way through the top but leave a thin web to hold the "plug" in place. I fin...

simple veneer type rosette making

Here is one way to make a veneer style rosette that is popular with some makers. After you find a suitable piece of veneer you lightly tack it down to a piece of scrap with spray contact glue. I like to use the cheap craft type spray glue because it doesn't create as strong a bond as the better glue...

Re: Left handed block planes? Or hand agnostic?

A few other "hand agnostic" are the Stanley "cheapies" 110 and 103. They have very simple mechanisms for holding the blade down, but once you get them adjusted they work O.K. The smaller 103 is actually a very handy plane for lutherie work. You can usually find these planes at flea markets for a cou...

Re: Left handed block planes? Or hand agnostic?

One of my favorite block planes is a Sargent low angle model. It doesn't have Sargent stamped anywhere on it but it is one of their designs. You can find them on eBay from $15 on up. On a quick perusal I saw a BIN for $19.95.

Re: Using Kydex in the Shop - More Anti-social Distancing

Hi Barry, There is high humidity in the shop at times, and daily/nightly temperature variations also cause humidity issues (have you ever checked the hourly variation of humidity for your locale? In the Houston area the humidity will vary from 64% to 91% today and tomorrow from 93% to 28% (predicted...

Re: Can this live again? 1941 Epiphone Triumph

It looks like you are doing a fine job with the repair work. I think that type of burst should work well to help hide the repair patch. I would do a few coats of clear and then put color in the finish rather than stain the wood and risk the old wood taking stain differently than the new wood. Other ...

Re: Using Kydex in the Shop - More Anti-social Distancing

I have a set of blue chip chisels that came with the plastic end protectors. In my non environmentally controlled shop I noticed the end protectors held moisture and allowed some rust to form under them so I quit using the plastic "protectors". Kydex looks like a handy material, but I wonder if it w...

Re: poor man's saddle mill

Nice looking bridges, Carl, As many discussions as I have led astray over the years how could I take offense? Whenever I see something I am curious about I ask. We are here to share experience and knowledge. Over the years I have been slightly modifying the design of my "take down" travel guitar (gu...

Re: poor man's saddle mill

Hi Carl,
I start them with a half moon blade mounted in an oscillating saw, and then widen and "ramp" them as necessary with various saws and files before gluing the bridge to the guitar. The windings at the ball ends are fatter than the string so that is taken into consideration

Re: poor man's saddle mill

Here is the "old" design. There was another design in between that used a closed slot - it gave more foot print, but no additional strength to the slots. The latest design is probably the heaviest of the three - gain some, lose some.

Hi Carl, This is the latest permutation of my travel guitar bridge. It is made so the strings slip out the back and remain with the neck. The neck unbolts and slips into the body through the tail port of the guitar. The neck is retained at the peghead in a recess in the head block and bolted through...

Re: poor man's saddle mill

The reason I use - three - clamps placed over the sides is I don't want to place "tons" of clamping pressure on the edges of the body. One clamp slipped on my first pass, but two kept things held in place. I reset the third one before the next pass.

Re: poor man's saddle mill

The router is placed in the jig and the bit is located at the "start" and "stop" ends of the rout and fiducial marks are placed on the jig. These allow a clear view of the end points of the rout. The router is adjusted to make a shallow cut, placed in the jig , raised so the bit is slightly above th...

poor man's saddle mill

I was routing a saddle slot today and thought I would post a few pictures of the way I do it. I like to rout the slot after the bridge has been glued to the soundboard, and in this case, after the guitar has been strung up and the best saddle location found by placing a temporary saddle under the st...

On a guitar where I am trying a lot of things I haven't done before, I glued a pinless bridge on with CA on top of the finish. So far it has held up fine. I considered what would happen if it fails, and I am thinking worst case scenario it may take some finish with with it if it goes. For a plastic ...

Re: Attach routing template to spruce top

Most soundholes are close to 4 inches wide. If you clamp at the far end and use a trim router ( take several shallow cuts) you may be able to get by and not mis-align the jig in the process. A PC 690 has a 6 inch sub base, and you would only need a little less than 1/2 that distance for clearance, b...

Re: Rebuilding an old Hungarian Citera

The pins look like they are hand made, and that may be what you will need to do to replace them. If the tuning pins are "stuck" heating them with a soldering iron may help to unstick them. You don't want to get them so hot they burn the wood. Where they are broken off flush with the wood and if you ...
