I take it down to the local joiners, and for 10 bucks they true-up the two large faces and square one edge.
I get them to thickness it to 75mm in the process.
Then I slice off planks at 75mm wide, and I usually cut it around 2mm.
I do that on a table saw, which is why I can only do 75mm high.
There is a bit of variation in the cuts unless you’re really careful, it’s hard to keep it perfect every cut, and once you get off line it’s hard to get it true again.
So I cut around 2 - 2 1/2 mm thick and plane down from there.
I run my electric hand planer over the face of the block between every piece I slice off - a good trick.
I made a jig for my planer, so it works as a thicknesser, with pretty good results!
But just sanding them with a sheet sander works, like Paul says.
The way you cut the wood thin is to take it over to Ben’s house (Benny1) and he has a giant 14" bandsaw that use to be his grandpa’s. He might argue at first, but bring beer, aaaaaaaaahhhhhhhhhhh bbbeeeeeerrr
we bought several packs from them a couple of months ago
still need to find the appropriate core to attach them too
although a hollow would be nice it wouls also be just a bit more expensive with 1/4" skins
the woods real light
you can get 1/16" but it’ll take a fancy band saw (like a laguna with auto feeder) or a good table saw with a pro thin kerf blade (timberwolf etc).
We just cut ours as thin as we could on our band saw and ran it through a thickness planer to get it down to a smooth 1/8" with out alot of skipe with blade lock downs on the dewalt.
It’s a good wood
we’re doing the same with resawing of cedar and poplar boards and the paulownia is by far the lightest although dried wiliwilil and triple a-grade balsa may be even lighter.
I bought the 1x4 72" pack for 76.00 free shiping. Not to bad of a deal. When I asked about 1x4 10’ long 6 boards the shipping alone was 250.00. I passed on that.
I guess I got a great deal- 9 pieces @ 8 feet by 4" by 1/8" and 6 @ 8 feet by 3". The four inch (plu) pieces were rough sawn. The 3" pieces were planed smooth. All for $92 including shipping. It was an ebay deal, left overs from some guy’s project. I thought it was kind of pricey but I couldn’t find anything else. Now I realize I scored. Not easy finding full length pieces.
