To fret or not to fret when finishing a neck

Hello, I just received an unfinished, slotted but not fretted maple neck from Warmoth. I believe standard practice is to fret then finish but I’m curious if it might be better finish before fretting? I understand one would want to prevent finish from entering the slots. I’m and going to use tru oil and do a light finish, maybe three or four light coats. Thoughts for this beginner? Dave

My recent favorite neck finish is Boiled Linseed Oil. It gives a nice smooth, but not shiny finish when applied sparingly. As for fretting order, I would do the frets first so any potential damage to…

Sanding methods/mechanism routine

Good evening folks, lately I'm experiencing some sanding methods/mechanism frustration. Can't explain better than look like I'm regressing at doing it. The only thing changed in my building routine is that I'm currently using a CNC (I haven't used one for some years) for both bodies and necks. I have no problems with necks, but sanding bodies has become incredibly frustrating, specially around the edges. While I keep improving my c…

Wipe on poly over Z-Poxy?

Hello — I would like to finish a mahogany electric neck and body with wipe on poly (probably Minwax satin) and would like to pore fill with Z-Poxy. I can’t find a definitive word on their compatibility. - Can I just wipe on the poly coats after block sanding the 2-3 Z-Poxy coats? - Should the Z-Poxy be sanded all the way back to wood or just smoothed/flattened? - Is a coat of unwaxed shellac between the Z-Poxy and the wipe in…

I personally like to do a washout of shellac just in case.

Replicating Kurt Cobains 59 Martin - bad idea?!

Greetings fellow Looths! I recently received a request from a customer to replicate Kurt Cobains 59 Martin, starting with a Sigma DM3. I have pasted the customers email to me below. While I have been a looth hobbyist for many years, I just recently opened my official business, Finger Lakes Guitar Works, and am just getting off the ground and a good flow of repair work is already coming in. While I feel 100% confident in my abilities to…

Seems kinda annoying to me. The guy wants to spend a ton of money building a replica of a guitar but he's going to not use a guitar by the actual brand to do it? I'm going to go with this is going t…

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…

New Acoustic Build - Having trouble

Hi all. Brand new member. I’ve been building a classical guitar via kit from LMI for a couple of years now. I keep putting it off but recently became motivated to get back to it. Unfortunately LMI is out of business so I now have no one to go to to ask questions. I’m at the stage where I’m putting the sides together in the form. I followed the dimensions for the form based on the plans as I measured them, but the sides overlap pretty ba…

Structurally you are fine. When you glue this up (this is important), make sure your sides are clamped in the form VERY snug so there are no gaps between the sides and the forms. This will leave the…

Aging Toner on a Sitka Spruce Top

I'm fast approaching the finish coating of 2 acousitcs. The sitka spruce tops are really bright. I'd like to tone them down a little and have been scouring the web for methods. Seems like adding amber toner in either the sand sealer or more likely the first set of nitro lacquer coats might be the the ticket. I see Stewmac has a Colortone stain called "Vintage Amber" that can be mixed into the nitro. Anybody have expirience with this pro…

Hi Gerry, I recommend spraying a sealer chow it a light scuff and then one more sealer coat. If you are using lacquer, thin some 50% by volume and add TransTint or Colortone. Same dye and some of the…
