Re: Proulx side bender?

Thanks Mario, that makes sense. The solid form is much better at keeping curves smooth. It also stands up to clamping pressure better. Okay, yeah, I never really got the bars idea in a bender, solid form and a heat blanket sounds like the way. At the risk of hi jacking the thread, any comments on ha...

Re: Proulx side bender?

Looking at the picture of Mario's bender, it "looks" like there were bars going across from side to side of the bender, now replaced with blocks of wood. Yes?

Re: Home made thickness sander issues

I used a shaft with keyway the full length of the shaft (McMaster Carr) and made a hardwood key that fit the shaft. I cut keyways in each disc and slid them on the shaft. You might consider replacing the shaft with one that is keyed and doing it that way. Otherwise, I think glue around the shaft and...

Wax for French polish

I don't usually wax my French polished guitars but I am taking a guitar to a festival next week that will only have eight days of curing on the FP finish. I know, don't! But I must. The guitar will be handled by lots of sweaty guitarists. I've kept the shellac thin, with plenty of drying between ses...

Re: General Finishes Waterbase Topcoat - SM is pushing this - anyone tried it?

I've been applying EnduroVar over dewaxed shellac, the kind you mix yourself from flake and have had no problem. I recently got a pick guard on crooked and pull a bit of finish off right to the wood in removal (damn! but it touched up okay). This tells me the bond between EV and the shellac is just ...

Re: General Finishes Waterbase Topcoat - SM is pushing this - anyone tried it?

When I use Endurovar (or most anything else), I grain fill the b/s & neck with epoxy and then shellac over all including the top. The Endurovar looks good to me over this regime. I get a very high polish after a five day cure using a 14" wheel with dry Menzerna compound. As others have mentioned, do...

Sign of Hot Hide Glue going bad?

I've noticed the last batch of hide glue I'm using is becoming less viscous as time goes on. I store freshly made HHG in the freezer and take out 2-3 ounces in chunks as needed. I keep the HHG I'm using in a squeeze bottle and heat to 140F in an electric kettle with thermostat control. I do not leav...

Any thoughts or comments on the dampening qualities of EnduroVar or the lack there of? Versus nitro or shellac?

Re: Ebony neck? Wha?

In the final days of the Henri Selmer guitars, they made a few with rosewood neck shafts. Selmer fans know about these and there is an oh-wow, ROSEWOOD neck thing about them. I played one 4-5 years ago, however and was not impressed. Who knows if the neck is to blame but the sound was thin and witho...

Re: Gluing top/back with Hot Hide Glue

Maybe I should have fessed up to why I want to use HHG for back and top in the first place. I'm actually pretty happy with Titebond for this most of the time, but occasionally I find that I miss my top or back tuning targets and need to yank the back off to rework things, hopefully before binding. T...

Re: Gluing top/back with Hot Hide Glue

Interesting! I like the steam injection idea. Here is video where the top was quickly clamped down to the sides in a go-deck. Took about two minutes from the application of HHG to fully clamped down. He preheats the wood, though in my experience, not enough to really make much difference. Wood is a ...

Gluing top/back with Hot Hide Glue

I'm using hot hide glue more and more. For me, the biggest challenge is keeping it hot enough until clamped. I've worked this out with practice and warming parts with heat gun for smaller parts. Biggest part to date is a couple fingerboards I glued down recently. But how does one glue an acoustic gu...

The second one, FFT by Andrew Smith, is the one I use. I did not research others, some one recommended FFT to me and it has worked well enough that I have not looked for alternatives.

You can set limits on the axes, but the setup does not stick, the next time you open the app, you are back up to full scale. But, it is very easy to adjust the scales and limits by typical smart phone gestures. Two fingers spreading apart/pinching horizontally zooms the frequency axis in/out, two fi...
