Martin DX 175th bridge reglue

I have a martin DX 175TH that is in for a bridge lifting. I did some research and it has an HPL top and a rosewood bridge. I have some gluboost gel on hand but I was wondering if anyone has a better suggestion.

Varnish Repair - Cracking/Flaking alon edges

I'll open by saying I know nothing about varnish finishes, yet. I've seen this Brentrup mandolin with a varnish finish that has extensive lifting/flaking around almost all edges. Is there a process/chemical for consolidating varnish finish like this? (beyond the brute force GluBoost wicking I might usually do) In any of the violin video sessions, has this type of finish repair been discussed?

I knew Hans. At the time I met him (around 2016) he was spraying spirit varnish pre-made from International Violin. His mandolins ended up with slight checking a year or so later, but I had not see…

Need advice on my first repair job

I would really appreciate some advice on this repair that I need to do. I've built a number of (classical) guitars so far, but this is my first repair job. I have already set the expectations with the customer that I can probably fix it structurally but the repair will be visible. The guitar is modestly priced and of no historical significance so it seems like an ideal project to take on as a first one. The guitar suffered a blow on the…

It makes me realize how spoiled we are here in America. I shouldn't complain as to the time it takes to get stuff and that I can get it at all.

Epiphone LP Limited Edition severe fall damage

Okay gang I have a doozy of a crack repair. Young guy brought in a Epiphone LP Limited Ed. He had picked up the case while it was unlatched at the guitar took a nasty tumble. Severe finish damage, and the wood has a shear split in it as well. The undercoat is thick with a thin layer of nitro color on top. Spoke with a sweetwater rep and they said that the finish was nitro. Here's the guitar specs via Zsounds: Epiphone Inspired by Gibson…

Matching Fender's Capri Orange

Hi everyone, I’m messed up, dinged a guitar and now I need some advice. I was relocating a screw hole in the top of a capri orange Mexican made telecaster when my drill bit broke and I punched an extra hole in the guitar top. 🤦 I called the owner and told him what happened and he’s going to let me try and fill it in. I don’t do much finish work so I’m not sure what the best method would be. I’m considering gluboost and their MasterTint pr…

help with Liquid binding repair ingredients/process

Hey guys, I’ve got a crumbling binding issue on a 1977 Gibson F5 mandolin. After viewing the liquid binding repair video from Doug, I ordered the appropriate(I think?) chemicals to mix with my Gluboost Master Glu and attempt the repair. I mixed the titanium white with the Dioxane, and the Butoxyethanol, and then when I mixed in the Master Glu. As soon as I mixed in the glue, it got hot and smoked and turned into a solid mass pictured in…

Thanks Doug. that all makes sense, I ordered all this stuff right after I seen your video, in hindsight probably overkill to have this much. I actually do have some of the white fill and finish, I order…
