Re: Side sanding dish motor & side bender??

That’s a great idea. If you have a pic of any of the ideas please send! Sanding the rims can be hard going I find and also my side bending could do with a bit more accuracy. I have the sides in the mould and dish underneath when sanding but I see a lot of people have the dish on top and a 25mm pipe ...

Anyone able to have a quick check here???

Hello I have just closed the box on my first TG method guitar and done the tests. I am wondering if 1 I am reading the right peak for the back? 2 Should I sand further the top or expect it to drop from 200 to 180 when neck and bridge are on? I am going by 12-18 in bk 2 where it is expected that numb...

Re: Motivation

Funny story .. When I was serving my time as a carpenter the foreman would always make us take 15 minutes around 4pm each day when the place would be messy and do a clean up. It used to drive us mad but now 40 years later I do it all the time in my workshop and have a portable battery hoover that I ...

Re: Motivation

Hello there This is a subject I think about a lot (too much no doubt!!) I build as a hobby first of all. I have built approx 20 guitars...some good some not so good, since 2015. As they have got better I have begun to donate them to various causes. Some went to the local music college who gave them ...

Dave In The video TG only does 3 for each raw plate and ten on the finished guitar...?? Today again I got what seemed to be reasonably correct ( judging by the target numbers in 6.2 but still the cross grain test throws out very high numbers for some reason....from 150 to 300 which can’t be right I’...

Thanks Dave I think I have it set up ok because I bought the TG course online from O Briens so I am definitely getting there... I only do 3 taps for each test on half plates (LG,cg and twist) as per the video and then 10 taps for resonating test which I haven’t done yet . It definitely spits out abo...

That would be great Martin and much appreciated. I think I have broken the big dread of the TG method now and looking forward to advancing it. Wish I could help you with the painting but what can I say...!! All the best
