Re: tasmainian Oak soundboard or back and sides

This is a group reply So you guys are telling me if I went through bunnings and found a really straight grain piece for an acoustic guitar it would already be dry and stable enough to use, for back and sides or neck? And people would still buy a guitar with bunnings supplied tasmainian oak back and...

Re: Router bits

Cutters I use the most in my shop: - straight and ball end cutters for doing truss rod slots - double flute cutters with bearing guides (top, bottom, top and bottom bearings) for use with trimming up to templates. - a 45 degree bevel cutter for classical bridges (ramped backside of saddle slot). - a...

Re: Router bits

A router table one of the best tools I made up for my workshop. I got my hands on a Unilift router lifter and made up the table myself. At the time the Unilift was the bees knees of lifters but these days there are other makes available that do an adequate job. As far as router safety goes.....learn...

Re: Router bits

I've genuinely tried to research but I'm at a bit of a loss. If I was to write a shopping list of a minimum set of router bits, what would I need to: - do some contouring steps (eg LP's) - round over bit (tele/strat) - binding - finishing off body shapes using a template (don't know a better way of...

Re: Shellac finish question

LOL..oil versus no oil. I'm in the oil camp. I've tried all sorts of oil but these days I generally use walnut oil. I use as little oil as is required to allow me to apply some serious pressure and not have the pad get sticky. Anyway.... stick with Allan's sagely advice since you're already in the n...

Re: Shellac finish question

Do you guys think it would be possible to re amalgamate the cracks on the existing finish? The crazed layers haven't amalgamated with underlying layers so really you need to remove the crazed layers down to competent layers. I'd be cutting back until you get a nice uncrazed surface and go from ther...

I started out doing 4 coats in a row, just going over the entire guitar once per coat applying it wettish, 4 times in a row. After a 3 sessions of that (12 passes over the guitar) I changed to waiting 2 hours in between each coat. Still 4 in a day. I did 24 coats in total. It's possible your applyi...

Re: Suggestions for materials to "practise" with

I had a customer with a guitar I built for him that had one such inlay feature added. He asked for that feature to be included in future builds I did for him. I recently had to help a mate finish a guitar he'd started at a guitar making school that had shut down. Somehow the instructor had made a s...

Re: Suggestions for materials to "practise" with

It's a good idea to reduce risk of stuff ups by 1. going in with a plan and 2. not rushing.

If something doesn't feel right or doesn't make sense...down tools, step back and think it out.

I don't work without a plan....and being a bit anal I go to the extreme of drawing up a full scale layout of string runs so I get it right with things like bridge pin holes etc.
