Re: Lack of Pore Fill

At the risk of getting anal about this!... Link below has some useful info. If you want to read through it you'll see that thinning epoxies with a solvent always compromises the performance (that basically means hardness). You can use heat to lower the viscosity without causing probs, but it does me...

Re: Lack of Pore Fill

Here's what's happening. Zpoxy is a fairly viscous (thick) fluid. As you drag it on with the credit card it's actually trapping air bubbles in the pores. These get 'opened up' when you sand back. I don't like to thin 2 pack resins because you can easily compromise the correct curing (hardening). Inc...

Re: Guitar sized Heat Blanket & Ukes Query

Why not make your own pipe bender. Dead easy. I used an element from a small old electric hot water service, mounted in a short length of S/S pipe scrounged from a truck zorst factory (mine's 4"dia). Just a simple switch mounted in the end, and a tough right angle bracket to mount in the vice. Turn ...

Re: question for nz luthiers

The idea is to insert the (slightly bent) fretwire, ends first into the slot, then tap progessively in from each end towards the fret centre. This means that as the fret flattens the little 'barbs' on the tang shift slightly sideways giving a better grip.

Re: Guitar sized Heat Blanket & Ukes Query

Tod, I wouldn't bother with light globe heat. When you start cold, the side/slats are sticking straight out so the heat from the globes can't get to the ends. I found I needed to pipe-bend the bout curves by hand first, which then meant I couldn't load into my bender without disassembling the top ((...

Re: Australian woods for tops

Blackwood may seem an unlikely choice as a top wood, but I recently finished a Blackwood top Jumbo -built more or less as an experiment. Now I've got a customer desperate to buy it. But I don't want to sell it, -sounds too good! It is a comparatively thin top (2.0 - 2.2mm from memory) and I used Bla...

Re: crazy questions

I just finished an all Blackwood body Jumbo, with a Blackwood top. (and Maple neck!). I did thin the top more than I would Spruce and did a lot of work on the bracing scalloping. It has a distinctively different tone, very nice, sort of twangy/glassy without being harsh in any way. That difference i...

Re: Joining Question

Joining plates... I use QUOINS (good scrabble word!). -Really useful for many clamping/holding jobs. These things are used by printers, they're small metal blocks about 35mm x 15mm x15mm, and with the use of a square key they expand a few mm in one direction. So you just set up your glued plates aga...
