Re: Mitred Purflings

1. Razor sharp chisel and polished back to see the angle is crucial. 2. I have to use a magnifying visor as my regular reading glasses just aren't good enough. And pretty much everyone I know even with good eyesight would benefit from the use. 3. Don't ever think you can hide a small gap at a mitre....

Re: Indian Rosewood Sanding issue

Set the timber 30 to 45 degrees across the grain for the bulk of sanding. Take light passes and only go with the grain at the last pass or two.

This is good practice for any timber that wants to burn or clog either on the timber or your sanding belts.

StewMax Membership and Free Shipping

I just go a notice as an email. Perhaps because I have a luthiers account that gives me big discounts on regular prices. Don't know if the general public will get this offer. But here is the link and a heads up.

Leveling dust specs and other imperfections

This technique is not new, and I've been using it for close to 40 years, but it's amazing how many people (even pro spray painters) are unaware of it. The reason you want to do this instead of using a hard block and sand paper is that for one, a block will never cut the high spot down level without ...

Re: Guitar top and back radius position

Your choice.

For my ukes the tall block is 10mm deeper than the neck block as that suits the way I like them to look. As far as I'm aware, all the Martin guitar plans I've seen do domething similar.

Re: What difference lacquer makes to sound

Most of those fellows are US builders that had to switch and try different brands when their favourite closed up shop several years ago. I've only ever used Mirotone when I used lacquer so couldn't ...

It would totally depend on the timber and the 2K clear coat. As far as being durable, shinny, impervious to water, alcohol etc. no worries there. But the flexibility is really an unknown. Metal doesn't move anywhere near what wood will. Flex agents / additives are added to most automotive finishes t...

Re: Machining a bridge on the CNC

Yes, it's a pretty industrial design that has a 700mm x 1,200mm working area with 300mm of Z height and a 3hp ATC spindle. Built it about 3 years ago now as I couldn't find anything in this size that wasn't just a toy, or cost over $50K.

Machining a bridge on the CNC

I shot some video of the machining processes on my CNC yesterday of making a bridge. 6 different operations over about 7 minutes total to make a bridge that by hand I wouldn't really have a clue how to do without more jigs and hand work than would ever be practiacal.

I follow Kent Everetts method of doing the bevel cutaway. The process is pretty much the same. His video is available on Robbie Obrien's website.

Longer scale length to keep the saddle as close to the sweet spot as I can. Some times it's a challenge as clients might want the extra frets but also have small hands that they are not comfortable going to a much longer scale.

Re: how thick should a Uke headstock be?

It depends on the tuners that you plan on using. If you have them on hand then just measure what would be appropriate. Otherwise most quality tuners will you buy will also have a drawing letting you know the critical dimensions. Most headstocks you will find are in the 10 - 12 mm thick range. If you...

Re: Concert Uke with Bevel Cutaway

No, the laser doens't pose the problem. It's when you go to tap into place something like a diamond fret marker like I have that the occasional one will break apart.

This pink stone was fine, but I have another pattern that has several blobs of different colors that have less structural integrity.

I like the recon stone. I cut it with my laser. I imagine it would be dead easy with other tools too. Some of the very figured pieces I've use will fracture / crumble for instance when I do fret markers. The bond between the various colores not being too strong. As long as you use it with that in mi...

2mm should be easy for a guitar.

Figured timber takes extra care as the short grain is very easy to fracture.
