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.

Steam Box Idea... What's wrong with this idea?

Speaking of Trevor Gore... I've started using falcate bracing on my ukuleles and in making the braces, 3 strips of .0625" spruce are bent and then put in a bent lamination glue up rig using epoxy. Bending spruce is no fun on a hot pipe. It's slow, fussy, the fibers want to delaminate. I have been thinking about building a small dedicated steam box. Pulling all 3 of the strips out at once and bending them over a form with a metal back…

I tried it once for trying to bend mandolin sides. This was in 2006, back when the internet wasn't nearly as useful as it is today, so the attempt was pretty incomplete I think. If I remember correctl…

Modular Clamp For Acoustic Guitar Repair

So, I made a modular clamp based on the split clamp idea. Started on a prototype about two months ago and finished it. What I was aiming for was a clamp that I could use on the BOTTOM of acoustic guitars as well as tops to clamp cracks, cleats, braces, patches etc. Especially a clamp that would access small openings like "F" holes, small sound holes etc. Essentially a way to get a clamp to areas not accessible to jacks, wedges etc.,…

Anyone use vacuum clamping for bridge re-glues?

I bought the O'brien vacuum clamp and a pump to clamp bridges on new builds, but also to use for repair work. I got tired of making custom top and bottom cauls for every odd-shaped bridge that comes in my shop. The vacuum clamp works great on a flat surface with no pick guard. I put it on a J45 with a pick guard, and it won't seal. The gasket is too hard to form over the pick guard. I've seen YouTube videos of other folks using vacu…

Scott, Here is a pic of me using the clamp over a Taylor guitar that has a pickguard. I am able to get it to create a seal. The bigger issue for me is making sure to mask off the bridge pin holes and…

more side bending

hello looths - i'm building my first guitar. generally following (and enjoying) the gore/gilet books. after 3 tries, i've yet to get a crack free bend around the nose of a venetian cutaway with a mahogany side. i made a version of the fox bender - using clamps on hand for the waist and cutaway, and a pid temp controller (verified accuracy), and am using a stew mac blanket and three straps. the recipe for my last attempt was: sapelle (fo…

Fret pressing at heel transition

Please can I see some quick cauls for dealing with fret pressing at heel transitions? For pressed / glued in frets or clamping down lifting fret ends in this area. I’ve tried a few different methods now and not entirely happy with any of them

Nut files and fretting tools

Doing some workshop organization and found some tools I don't use. All are in excellent shape with very minimal use. Each item linked to the relevant product page: Japanese nut files. Mine have a bit of surface rust but they were used for maybe 2 guitars. $80 new, selling for $40 StewMac Gauged Nut Slotting File Set for Electric Guitar (for medium strings) and one of each nut file backer. Used on one guitar. $113 new for the files and $19…

Gibson LG-1 1957 fingerboard extension glue will not loosen

Today I have spent the better part of five hours attempting to get the fingerboard extension free on this guitar. I am using the method I have used for dozens of neck resets: 100 watt halogen bulb with heat shields. After a couple hours I thought I was making some progress under one corner, only to discover after some movement that my palette knife was going through the top. I then abandoned that area and have been applying heat and…

Flattening Flatwork?

I've got this Telecaster pickup (1969). The pickup works. Is it possible to flatten the top without gluing it down to the windings? Clamping lightly with a caul slotted for the magnets seats it nicely but I'm not sure how to make it stay there. Any experience with this? Suggestions?

If it's working, you don't really want to. Plenty of people manage to cla.p down the ends and hit the pole pieces with super glue. And that can work. You run the risk of breaking the internal coil wir…

Strange(?) bellying on Martin 000-15 SM

Just realized that I posted this on the main feed earlier and should have posted it here. Apologies for my poor posting skills. Will go and delete the original now.... Hello all, I’m new around here and excited to continue lurking and learning, taking in all the great content and the knowledge of all you experienced looths. I am more familiar with building than repairing, but I am interested in learning all I can about both. I’m happy to…

Yeah, I don't know. I would start by calling Customer Service. They will either direct you to a warranty operation for verification or if they let you send the pics, they might just issue a Return Aut…

Print problem, 2nd layer

Got my new printer a few weeks ago, and I have been loving life in 3D. I have made a bunch of cauls and tools in preparation for my next builds. On all the prints the first layers were a little fuzzy, so I did some research and adjusted the z offset. Got my first layers in the pocket. But that caused some horrible problems. Now I can’t even finish a print. First layer is fine. Second layer is hairy and fuzzy. Seems like the nozzle is dr…

'88 Washburn Headstock recapitation

I'm working on a repair to a Washburn EA50 headstock. Someone previously tried to repair this with a dowel, which likely worked until it was strung up. I've routed a slot and created a biscuit, and built a jig to hold both parts of the headstock in the same plane and clamp everything tight (some cauls and threaded blocks of maple with 1/4-20 machine screws). The plan is to use System 3 gel epoxy (a'la Beau Hannum) and then add a coup…
