re: clamping. You may notice a neodymium magnet (n42) in one of my photos - I used it to glue the cracks. I have 10 of those and am considering experimenting with them to glue the bridge on. I would cut 3 separate thin pieces of wood as cauls to fit between the braces inside the body and put some p...

Allen is pretty much the guru when it comes to finishing...whether it be cars, ukes or guitars

Nice work Jim...

So you can hit the high notes?

How are ya truckin' Dennis?? Hope you've got over that building "flat spot" you were going through recently.

You ran out of glue??!!! That's like running out of milk mate!!

No bridge patch? if it were me I'd stick some sandpaper to the bridge area and work the base of the new bridge over the sandpaper fore and aft aiming to get the underside of the bridge matching closely with the top. Unless you have a good wood to wood contact over the base of the bridge the glue job...

Really nice work...that sheaok looks like it's on fire.

Mine are to 0.001mm.

But they are cut on my CNC.

Definitely micrometering the brick!!

A friend is about to make his first fret board and asks "What resolution do you measure fret positions to and what do you use to mark them out"? As a beginner I felt it prudent to seek some advice here (rather than mis-lead him) :) I know "The Books" say 0.1mm but is that typical of most makers? I'...

As some of you will know the forum is currently being administered by Jeremy and myself. Jeremy takes care of the IT side of the operation while I take care of more mundane tasks such as dealing with new members who are obviously out to spam the forum or emails from spammers. Here's an example of th...

Hi Dave, If you've already donated we're ok...if you haven't donated and want to tip a few bucks in the hat we won't say no :) At the moment thanks to our members who generously donated we have enough funds to cover forum running expenses for at least the next couple of years. Cheers and thanks Mart...

The static electricity issue causing sparks and subsequent fires has been debunked many times, static charge can be felt on the outside of the ducting sometimes, I have a bit of copper wire around one length of flex duct that is grounded to the shed that I brush up against regularly, only because t...

You'll get there John. Maths isn't my best subject so it took me a while to get my units and zeros sorted out. Trevor at first seems a bit cruel when he doesn't always give you the easy answers but by not doing so he's prompting you to go back and understand the equations. Ok, Thanks Trevor! I've re...

There seem to be widely varying opinions and advice on this one. Discussed at length here: http://lumberjocks.com/topics/14140

What about copper wires earthing the pipes to stop static electricity and sparking, are they still necessary this day and age?

Pencil lines to show when I’ve sanded for long enough on the radius dish:

No pencil lines required for that mate....I just keep sanding until my arms are ready to drop off

Allen,

Ive tweaked some settings so you should be able to upload pics now. Let me know if still having problems.

I'll get Jeremy to have a look at this. Anybody else having problems?

For the last day and a half I’ve been getting HTTP error message anytime I attempt to upload a pic, so the thread is a few updates behind.

Hi Richard, A 1/2" mortising bit is probably cutting it a bit fine, especially if your heel gets smaller than the one on the drawings in Trevor's books. You should be able to source a 10mm/3/8" bit for that Carbatec mortise kit. Is it the full mortising machine or the kit you attach to a drill press...

Thanks for that Allen. That's detergent and water in the bowl at start of the clip?

Nice looking bending rig...someone's got some loot

Unfortunately I didn't do any tap testing on my last uke build. Allen has commented in the following discussion on the Ukulele Underground Forum: https://forum.ukuleleunderground.com/sh ... tap-tuning

I've done this more times than I care to remember. You can go in with alcohol and then finish off with sandpaper. Sometimes I start with a cabinet scraper before finishing off with the sandpaper. Other times I've gone with sandpaper all the way from start to finish. The great thing about shellac is ...

All looking good Allan do you shape the bottom of the braces to fit the dish radius? Trevor Gore has a neat method for securing braces in the go bar deck. A strip of MDF with a channel cut down the middle with a ball end cutter. The channel fits over the top of the brace and the go bars apply pressu...

You can always go down the route that some less well known brands go and just slap on your bindings with a paint brush.......or you can do what more than one major brand is doing at present and not bother with bindings.

I wouldn't be playing around too much with everything. Once bridge is on I'd expect a few Hz drop in main top frequency. I sometimes stick a bit of mass on the top roughly equivalent to the bridge mass to see where things might go with the top frequencies. I'd probably be aiming to keep the bridge a...
