Re: Unisaw belts

If it uses a standard v-belt, I’ve found these power twist belts to be worth the money. https://smile.amazon.com/gp/slredirect/picassoRedirect.html/ref=pa_sp_atf_aps_sr_pg1_1?ie=UTF8&adId=A0556096194W1P6X5QJT3&url=%2FAUSPA-Power-Twist-V-Belt-2-Inch%2Fdp%2FB075WRBHXB%2Fref%3Dsr_1_1_sspa%3Fcrid%3D23PM...

Re: Bolt on issues

I use a bolt (with the head cut off) that fits the insert. Without removing the neck from the clamp when I drill the hole for the insert. I replace the drill bit with the bolt (insert attached). I then screw the insert into the heel by hand using the drill press to keep the alignment. My new drill p...

Re: Bolt on issues

I use a 1/2” maple dowel with the edge 1/4” from the heel surface so that a 1/2” deep insert is imbedded halfway into the dowel. I use LMI glue—Titebond would work fine. Every time I order a new bundle of dowels, I find that the diameter changes slightly. Among my 1/2” drill bits, I pick the best ma...

Re: Bone direct from India?

Thank you, Alan. At least for me, it sounds like it’s worth the extra money to buy the saddle blanks from the normal suppliers. Are the unbleached parts from normal suppliers okay? I’ve used the pure white pet store bone to make odd sized saddles when I didn’t have an appropriate blank. I’ve never b...

Re: Formica guit AR-7

The redwood I’ve bought from Vincent Strauss (Pacific Coast Tonewoods) seems to be good. I like to make a guitar occasionally for extra light strings or silk and steel only. I’ve been reserving the redwood for those guitars—the extra light strings can drive it and there is less stress on the soundbo...

Re: Formica guit AR-7

I don’t remember how it tapped. But, the guitar sounded wonderful. It was a shame it didn’t have lasting power. I didn’t have another piece of redwood then, so I retopped it with Engelmann. IZt still sounded good but in a different way. I’ve made another redwood topped guitar since then. That top ha...

Re: Formica guit AR-7

My redwood failure had a thin layer of redwood attached to the brace all along the glued surface. I did the experiment with a cutoff after a brace came loose on a redwood topped guitar. That top also split. I retopped that guitar. When I r3moved the topped, the braces pulled off with a layer of redw...

Re: Formica guit AR-7

I made a Wilsonart (Formica of another brand) guitar a couple of decades ago. I used epoxy almost throughout so it wouldn’t dissolve if it fell in the water. With a little experimentation, I settled on polyurethane (Gorilla) glue to attach the bridge. The guitar was okay, but I didn’t like it. What ...

Re: Martin 0-18 with multiple problems

Not to sidetrack the discussion, but this is the perfect entry for an ethics question. Some years ago, I had a customer bring me an aged Gibson with a cracked and unrepairable Brazilian rosewood bridge (it was cracked in all the wrong places). At the time, I had a piece of Brazilian so I made a new ...

Re: Wow! Rulers Are Not the Same! Recommend An Accurate Straight-Edge?

My first PEC ruler arrived yesterday. A couple of my printed rulers failed the comparison. The one I had thought was most likely to be accurate, the Ibex fret rule, was off. Dang! The little 6” ones I use most often, one a General, the other an Empire (metric), were right on (easy for that short len...

Re: Wow! Rulers Are Not the Same! Recommend An Accurate Straight-Edge?

I’m waiting until my new rule arrives to see which, if any, of the rules I have I can keep. I’m hoping that some are correct so I don’t have to replace all of them.

Re: Wow! Rulers Are Not the Same! Recommend An Accurate Straight-Edge?

Wow! I have many rulers of many lengths in my shop that I select for convenience for the task at hand. I never thought to compare them. Now I know that my inches and centimeters are many lengths. I guess it’s no wonder that measured things don’t always fit tight. I will have to be consciously consis...

Re: Triple O - Dovetail neck doesn't seat - Photos

Please excuse me if I’ve misread this and tell you stuff that you already know. It’s been 28 years since I started doing this by building a kit. My kit was from Martin. The dovetailed neck and dovetail block were supplied overly tight so they could be fitted after the guitar was made (the thickness ...
