Air dried ash

marcros · 13 Sep 2018

Does anybody near Leeds have access to air-dried ash?

I need a board, for steam bending (or laminating). I only actually need a couple of metres of 4 X 1. Colour not particularly important, it is for a toboggan, not fine furniture.

I assume that I need air dried for laminating, I know that I do for steam bending.

Air dried or green(ish). I have bent kiln dried it's not great but it will bend a bit. It's very much about the wood. Some won't bend. If it's been in log for a few years it won't. Quick grown straight grain mature coppice is the best. Followed by a youngish white tree. Olive and ripple aren't good. Olive is brittle.

Any Windsor chair makers in your area?
They should have a supply of green ash.

It depends on the thickness of individual lamina plus the radius, but basically the answer is no, you don't need green or even air dried Ash for this job. I'd probably think about lamina that are around 5mm thick, and I guess the radius on a toboggan runner would be, what, about 250mm?

That's just not going to be a problem. Make sure you use a UF glue like Cascamite (PVA will creep and won't give you enough open time), and leave the job in cramp on the former for three or four days to let it thoroughly dry out.

Over the past few years I've done loads of subcontracted lamination jobs for yacht fit outs, and I've used kilned timber for pretty much all of them.

Ah cool. That makes it easier on several fronts. I haven't done lamination before, so had assumed it would be 2mm or so.

The plan is to make the runners about 25mm thick, so 5x5mm doesn't sound too bad. 250mm bend sounds about right, this is what my daughter has her eye on. https://www.hornbach.de/shop/Schweizer- ... tikel.html

Not next door, but Scawton Sawmill here in North Yorkshire have a good supply of French Air dried ash.
