Ovalized Rim Repair

[Dekes]

A couple of years ago I bought 2 used planet X BMF, which are rebadged Alex DX32 rims, from a friend for £15. As my current try all rim is a bit worn, I wanted to lace one of those planet X rims onto my rear hub. I randomly took one and noticed it had a rather large difference in spoke tension at the seam-valve hole, compared to the perpendicular direction. I took a folding ruler and measured the difference, the diametre at the seam-valve hole was 5mm larger than in the perpendicular direction to that.

When measuring the other rim, there was only a 1mm difference in any direction. I tried sitting on the first one, but it didn't give in anything. Have you guys ever had this problem too and how did you fix it? Thanks.

Over tighten the spokes with too much tension, you might ruin a few nipples though so I'd suggest using brass.

Once you done this and true'd it, ride it for a while and then delace and rebuild it with correct tensions.

So is there a system and torque settings to fitting spokes?

I had measured the rim unlaced, which is rather stupid and thus making this thread a bit obsolete. After lacing, the rim ended up just fine, except for a 2mm downward flatspot over 2 adjacent spokes, probably caused by the previous owner and not really mendable. This isn't really a big issue for a rear trials wheel anyway.
