Re: Bending Macassar Ebony sides at what temperature?

Planing leaves a smooth hard uninterrupted surface. Sanding effectively destroys the surface the depth of the grit. So a side sanded to 1.8mm has the stiffness of a slightly thinner side which is an advantage when bending. A side planed to 1.8mm has the strength of a 1.8mm side.

Re: Shed* (Workshop) Advice

I built my workshop from a shed frame. It has Hebel panel cladding that is screwed onto the shed frame instead of colorbond steel. The Hebel panel provides insulation and is fire proof, but you need to make sure the foundations are big enough to support the extra weight. I lined it with insulation ...

Re: Bending Macassar Ebony sides at what temperature?

I've no idea about temperature as I've never measured it. But what I can offer that would be useful here is to soak the sides in a hot water with a cup of fabric softener for half an hour. Enough water to cover them, then weigh the side down so it doesn't float about. Wrap in baking paper and bend a...

You might want to ask your insurer about what effect building with SIPs might have on your insurance. Some really don't like them.

Re: Shed Advice

Depends on how much time and money you want to spend. If you can, insulate and seal the whole thing, buy a really good dehumidifier like a Thorair. For a smaller cheaper unit, I've heard good things about the Midea Cube. At the least, make a small room you can get a gobar deck in, along with whateve...

Re: Pore fill question

I've been using a very simple and effective pore fill for the last few months. Prior I was using epoxy. It worked, but it took longer than I liked. 1) Having sanded to 320 grit, seal the back, sides and neck with thin superglue. I use Starbond heavy Thin, though the fumes are foul. Make sure you're ...

twin side bender

Don't know if I've posted about this, but a while ago I realised I could bend a side in not much more time than I could put one in a machine, so I thought it a good idea to make a bender that could handle a pair of sides at once. I based the design on the Mike Doolin machine where the slats are unde...

There really isn't any money in making cases which is why no one wants to do it. For a while I couldn't source cases for my Big Celtic mandolins, so had to buy heavy duty rifle cases. The inside foam was laser cut and my wife would cut and stitch fabric to cover the foam. They were pretty expensive....

Hi, that's a nifty-looking setup, how is fret spacing arrived at? I suppose you could make kerfing on that too. Taff Same as most other slotting set ups. With a template and a pin. You could make kerfing but there are better ways. You'd need a wider blade than 0.6mm too. I like jigs that are more a...

I've not slotted a board for years. Ebony dust was really doing me in so about 10 years ago I shipped all by fretboards to a lad who slotted them and radiused the lot on his cnc for a very reasonable price. But I'm starting to get to the end of that batch. I've also been using LMI for their slotting...

Thanks Nigel.

Who was the guy a few years back who tried to claim semi hemispherical fretting as his own? I believe there were some legal threats made at the time.
No idea. I thought Harry Fleishman came up with it. Least he told me he did.
