Re: Updated Epoxy Pore Filling Demo - Video

I switched to BoatCoat several years ago and would never go back to WEST Systems. For the first application I use their TPRDA thinning additive that really allows the resin to penetrate into the timber and get to the bottom of the pores. As I'm always building more than one instrument at a time, I w...

Updated Epoxy Pore Filling Demo - Video

A new video I shot to demo using epoxy resin filling a mahogany baritone ukulele. Some might find it useful.

I'll be shipping this one out next week for a client in Sweeden. Australian Blackwood with Yellow Cedar soundboard. Ebony fret boards, bridge and head plate veneers. SuppleJack bindings. Sap wood from an offcut of the back, and burl from some local tree that I have no idea what it is, but the color ...

Re: Bulloak

I've used it for bindings at 0.070" and 5 mm tall. Don't recal it being a problem but the edges are extrememly sharp until rounded over. You could easily cut yourself on them.

Re: Acoustic Bridge Types ...

Can't say you'd ever be able to determine a difference in sound. I far prefer the string through bridge. Can be with bridge pins or without. I like without. Nice clean look and it's actually dead easy to restring. But it's surprising how some people are confused by the process. I've had a few music ...

I had mine insulated with foil lined fiber batts. My mate is a roofer and told me that for up here in Cairns that was by far the best option. The roofing sheets are pulled off to install.

Re: Opinions wanted on use of this Sitka top...

I have plenty of soundboards that have wide grain spacing but so bloody stiff that I end up taking them thinner than others that would have narrower spacing.

Lots of my clients would pick that top because it looks like timber.

Re: Mouldy HHG

I presume you mean in glue that has been made up. If it's mouldy then toss it and make fresh. If you can't use up what you have in a resonable amount of time, then just make smaller batches. I mix up either 1 or 2 tablespoons of glue with double that in water in a small mustard jar that gets stored ...

Re: Bote-cote epoxy

It has a very long shelf life. I buy the 1 litre resin and I go through it in about a year. I know that the regular and tropical hardener will yellow with age, so I always use the non-yellowing hardener. I typically make up 10 grams of resin plus 4.4 grams of hardener to pore fill a couple of instru...

Re: Bote-cote epoxy

Only when pore filling. I found that with some timber it works better to use the TPRDA in at least 2 coats, but that could also be that I'm in the tropics and it will want to kick over quicker than in cooler climates.

Adding the TPRDA definately thins it out so it penetrates into the timber.

What is Bote Cote like to sand in comparison to West’s and Z poxy?

Rod.
Never used Z Poxy but compared to WEST Systems it sands like a dream. You'll kick yourself into next week for not switching sooner.

Yes, the endgraft sides have a curve to them. I cut them on my laser so they are the same every time.
