no previous part Part 1 of Steve's 2x4 Challenge series Part 2: It takes shape »

Well, I started cutting up my 2×4 and did some prototyping.

Jointed and resawed a bit. Then I sent them through my little Ryobi thickness planer. Even after letting it acclimate to the house for a week, once it was prepared, it still warped more than I would have thought. I had never resawed anything before as all I have is a craftsman bandsaw. But with a new large blade, it worked much nicer than I would have thought. You can see the bandsaw in the background.

I had never really used sliding dovetails for joints. They really lock into position. I like ‘em. I cut them with a little sliding jig on the router table. I thought that I better not use the CNC, as that might be a no-no for this contest.

I won’t be able to get any more done for a while as I ‘have to’ go spend next week in the Caribbean and escape winter.

Looking good!

I’ve had the problem of twisted wood after re-sawing a 2×4, you’d think that being kiln dried would

prevent this, but maybe they’re not dried enough.

I know what you mean about warping.
When I cut and planed the pieces for my top wing of my 2×4 Fokker, the next morning they looked more like a prop than a wing. Lucky for me, I had left a bit of room for error, but if you look close the wings are twisted a bit.
Looks like your off to a great start. Time out to head to the Caribbean. I know that one too. I’m off to the Dominican Republic tomorrow morning for a weeks break.

Thanks people. Yeah, the warping was way more than I thought. I jointed, waited two weeks, jointed again and resawed. Two days later, they warped again. Oh well, this is the first woodworking I have done since joining LJs and it was great fun.

Yup, off to St. Martin for a week with the wife unit for the umpteenth aniversary.

Looking good…. and St Martin is nice. I’m hoping I can make the time to do my 2×4 project. I already have two paddles that I’m building to take to Maui with me in February. Not sure if I can fit another in. I can’t wait, my brother invited me out to help him with this.

Hi Steve,

It’s been a boring night…So I’m checking reading all the blogs, a lot of your work is interesting to me,

so I find, later I need to check out your work with the vacuum press, I’d like to get one but there pretty

expensive for me. In any case I’m checking out this project and I have a solution to your twisting boards

1075 days to late!!! I turn cnc lathe using a vacuum fixture as opposed to chucking the material. We work

with exotic plastics that are annealed, turned, then milled. Most bowing and twisting that we encounter is

due to stress in the material. Your 2×4’s are stressed in the same way, the out side dries faster than the

inside, so over the course of a couple days the material wanders back. If you joint the wood say 8 or 15 light

passes that part is good. Next with the planer double stick tape the jointed wood to a larger // and square

board. Take light passes Thur the planner no more than .01 per pass until you are at the desired thickness.

The first few passes you just want to take the high spots-so light you have to push the material Thur as opposed

to feeding Thur the planer. The idea is to have as little pressure applied to the board as necessary by the

planers feed rollers. The rollers are actually applying enough pressure to compress the wood enough so

that it will spring back to it’s former twisted state. Also note Joint the convex side, plane the concave

side. To much to go Thur for a 2×4, but you might run into a situation where you are using some good

wood with to high a moisture content.
