Re: Jim McConkey's Flood Mandolin Twins

Another option, I suppose, is to get a long 1/8" drill bit, and drill the heel and neck block from the strap button hole, then added a screw. HAve the screw already in the neck block, apply hot hide, and snug it up with the screw. That said, I'd rather see you pin it from above. Nice project; w...

Re: Jim McConkey's Flood Mandolin Twins

Hmmmm, yeah, the pins had to go in before the backs went on.... Pins --can-- go in from the top of the neck, as long as the fretboards aren't glued. Find the angle that will see the p9n intersect both the heel and the neck block for at least the bottom 3/4" or so. If the neck pocket fit is good...

Re: fixing a poly finish ?

Before you try anything, give us more photos. Different angles, different lighting. Hold a straight edge to it to show how much it is puckered. At any rate, never hit CA with accelerator when doing a repair. Yes, it may work, but it may turn white. Depends on humidity and other factors, but CA is fa...

Re: Top Damage Advice Needed

No sawdust and glue! That just highlights everything....

You have an excellent opportunity to learn to steam out dents. It's not hard, you can't do it 'wrong' on a raw top like this(as opposed to a completed instrument) and you'll learn an invaluable skill.

It will come out perfectly.

Re: Sign of Hot Hide Glue going bad?

I have been using 192 high clarity for bridges for 17 years. Nary a problem, despite my bridges being most likely the tiniest in the steel string guitar world... No amount of time at room temp is good. I've also given-up on freezing mixed glue. Freezer burn is real. It's not -that- hard, nor does it...

Re: String mass vs tension = volume

One of my models has a 24" scale length and I recommend running mediums on it, because I, too, like the tone of heavier strings at lower tension. Turns out that mediums(13-56) on a 24" scale are nearly identical in tension to lights(12-53) on a 25.5" scale. I get the benefits of lower...

Re: Nut width/string spacing vs bridge string spacing

As long as you taper the neck according to the two spacings, all's good.

When I built my tele-type last year, I did precisely that. Not quite 1-3/4" at the nut, but close...

Re: sticky Waverly tuners

This is an installation issue...

Waves should be installed in a snug(but not tight) hole, and shouldn't really be touching the bushing. You must drill the holes in steps, one size for the shaft, the other for the bushing.

Re: Fretting, backbow

Careful not to make the frets fit too "nicely". Wood moves with seasons, and what might be a nice fit in your shop could end up being too loose if the instrument lives in a dry environment, leading to frets that can pop-up, or at the very least, inconsistent fretted tone...
