Usually the best method to remove twist from a piece of timber is to cut it into smaller lengths, but what if you really needed the length effected to stay the same.

As I had two pieces left over from my Tool Trolley project which were” badly” twisted this got me thinking as to how it could be done.

So they all have what looks to be very bad twist and not worth persevering with.

I know you could mount it on a sled wedge them up and run it through the thicknesser, but what if the thicknesser was unavailable?

It may be possible to do them on the jointer freehand so I “fiddled” about trying to work out how you could hold them vertically and remain stable away from the fence.

As you usually joint timber with the bow up I worked out that you may be able to support the center section with sacrificial blocks to stablise it as the timber was jointed.

So I set up piece 2, as it appeared to have the lesser twist, in this jig.

Ran it through about for times and examined the results

It seemed to be OK so I removed the jig and jointed the other side and checked it again.

From what I saw it looked like it was going to be an exercise in making wood shavings from the amount of material that had been removed.

Anyway I set up the table saw and continued.

The edge trued up OK so I continued on the side, taking a bare min pass first up, then reset and resawed to 35mm
It worked well so I did both pieces.

Here are the results.

Next was a check on Squareness.

Position 1

Position 2

Position 3

All looked like they were good so as a final check I layed them out together and checked the edge profiles against each other.

Profile Position 1

Profile Position 2

Profile Position 3

Profile Position 4

I then wondered just how much material was removed in the process, so I checked the work with a rough sawn original

Results
From the two “discarded” original pieces I found that there was no more than 5mm removed to return the timber to a servicable condition, quite surprising after seeing the winding sticks, so,

Conclusion:

Was it worth the effort?

Factors: Time taken about 1 hr, material cost nil material worth effectively nil again, as it was some very soft pine doing the same with a piece of hardwood may possibly take longer and produce more wear and tear.
So consideration to the time taken, material worth and other factors it may be a possible stop gap measure/save but not much else.

You got some good practice in on some cheap wood…
Next time, the wood might make it Worth it… :)

You did good!
