D28 blowout

Hi all, I'd like to get some input on how to address this top blowout. For starters I own this, I got it as a project guitar, 71 D28. I'm not as experienced with acoustics as electrics and this is a big project but I got it to learn new skills and I'm confident I can do it with guidance. It had been stored in the case for many years under tension and was way too humidified. The bridge had pulled up I assume in stages. The center seam se…

Non-CNC cauls for Stew-Mac sound hole clamps

I don’t have CNC capabilities so I could not duplicate Dave Slimmer’s version ( https://loothgroup.com/loothprint/bridge-clamping-cauls/). Got a 12x18x1/2 inch HDPE cutting board on Amazon for under $10 (https://www.amazon.com/dp/B001D3LQVA), drilled a row of 1/2 holes about 5/16” deep with a Forstner, cut the HDPE into 5 sided chunks so I could orient by touch, and free handed the brace grooves on the band saw. The clamp swivel pads are 1…

Yeah, I think the current concerns with microplastics is impacting cutting board prices.

Tool for shaving back braces

I am retopping a guitar and while it's open I want to reduce the mass of the back braces. Since the sides are in the way, I can't figure out how to cleanly cut the excess brace wood away; anything I've tried involves the handle hitting the sides and preventing a controlled, clean cut. Is there a tool - say a "pull finger plane" - that I can pull from the edge to the middle of each brace to facilitate this?

My problem in this parlor guitar is that any chisel I currently have is too long and I can’t address the middle third of the brace without coming in at such an angle that I can’t control the chisel pr…

Measured drawing and assembly for Proper Variable Radius Sanding Jig

Doug Proper designed a sanding jig that supports variable concave and convex curves, described in the following Loothgroup article: https://loothgroup.com/post-imgcap/the-variable-radius-sander/ I built one and am impressed with how it facilitates preparing bridges, braces and also allows tracing any radius using the chord formula. I made a rough measured drawing and assembly guide to share, with Doug's blessing. First step, ma…

Brace Brace

Hey friends, just wanted to share a thingy I made and have been finding very useful for a couple years now. Ive intended to remake it prettier ( former helper did the file work), but this one works fine and I'm busy. I call it the Brace Brace. It hugs a length of the loose brace, and puts nice pressure across the brace, but most importantly on the scalloped end against the kerfing. I loosen one side of the other, then tighten it in…

Do-everything Vacuum pump?

Anyone have a suggestion for a do everything vacuum pump? I'd like something that could laminate sides, brace tops, laminate double tops, etc etc. I know @member@member has a cool cheap one. I'm not sure if that's powerful enough to do all building tasks? If it is, that's cool.

Thanks for that and sorry for the delayed response! What sort of pump would I be searching for for a used industrial pump? I see a lot of used medical ones but they are in the 1cfm range, I'd ideally…
