Re: matching the chayotiance of a four-piece top

All you have to do is look away for a second and you won’t be able to remember which piece is which in which orientation, so you’ll have to hold it in its intended place and rock the top back and forth to see if the piece belongs there. What you say seems to be right, and with careful marking of the...

Why not make a solid wood floating bridge like the one in the Elderly Instruments photo?

Re: KTM-9 - compatible waterbased substitute?

Brushing works. Use a very supple synthetic brush. Brush very thin coats. Build it up like you are spraying. Level sand when appropriate. Patience is rewarded.

Re: KTM-9 - compatible waterbased substitute?

I generally use up my EM6000 within 2 to 3 years of purchase and have had no problems with it. The KTM seems to have a much more complicated formulation and I think had a stated shelf life of a year or less. I’ve only used one quart of it in my life, no longer have the can, and don’t miss it. The fi...

Re: how to avoid fumbling the nut

Great idea! Many times I have gotten out the magnet on the end of the telescoping wand for that very purpose.

Re: KTM-9 - compatible waterbased substitute?

Target EM6000 will match it pretty well but it is not as hard and scratch resistant. I believe that it was recommended by KTM at one time for repairs. You’ll need to fine sand the KTM to get a mechanical bond.

Re: Alvarez “bridge”

I’m going to leave the crack, but I feel like I have to fix the string balls pulling through or there will be a much uglier repair to do later. The pickup is in the bridge part of this concoction. Note the individual saddles. I’m not going there.

Re: Alvarez “bridge”

Steven, thank you for that reference. Now I understand why it looks like it does. This one seems to have a large ebony (or some blackened wood) rather than the T-insert through a maple plate. I don’t know how old the guitar is. The owner has had it about 16 years and says the between pin cracks came...

Alvarez “bridge”

I haven’t worked in one of these before. I would like to believe that the crack in the flush bridge section is of cosmetic consequence only. Does anyone know what the inlay material is? But, the guitar has slotted plastic bridge pins and the string balls are starting to pull up into the bridgeplate ...

Re: Banjo neck angle

I make open back banjos, usually with a 12” rim. I’ve tried chasing a number for what is considered the best neck angle for a banjo. The bluegrass guys seem to think that 3 degrees is optimum, but for a 5/8” bridge, that puts the strings really close to the head at the edge of the rim which isn’t op...

Re: REPAIR

I’ve been doing the dental composite with eBay stuff for a couple of years. So far, it seems permanent. It sure is easier than remaking the nut. My experience with the CA plus anything fills in the nut slots is that they are very temporary (but useful when you only have a minute).

Re: Shop air filtration build - Advise welcome

That would be it. Lowes gives a discount when you buy 4. All sizes cost the same, but you get more filter surface the bigger the filter. I use the 20x25. I took one apart. The pleated filter was 8 feet long.

Re: Shop air filtration build - Advise welcome

This is what I did. It sits on the floor and blows up to the ceiling. I use the 3M Filtrete 1900 filters. I have a duct that I attach to it when I spray to blow the fumes out the window (the box containing the guitar to be sprayed backs up to it in the front). A timer shuts it off so I can clean the...

Re: Replace or re-configure rattling truss rod?

Melted wax is a neat idea, but I worry that it’s not elastic. After a hot day or an adjustment, it may no longer do what it’s needed to do.

Re: Replace or re-configure rattling truss rod?

The round part of the rod is usually covered with shrink wrap tubing. I’ve always used clear silicone caulk and never had one bind up on me. If you really want to use something else, you might try a mockup with another rod like the one that’s in that guitar.

Re: Replace or re-configure rattling truss rod?

I always use the clear silicone caulk for this (the white stuff seems to set hard). Maybe a glue syringe (that plastic thing with the curved conical needle) would be a good way to inject it, or use the standard caulk tube nozzle penetrated with a small drill bit. My caulk tubes always get hard befor...
