Pretty good pictures.

I think I see one problem. Your shop is too neat. And it's also too large.

The rear view pictures were to see if any obvious warps were present. They aren't bad enough to show in rear picture. But rolling is really more often a warp or trim problem than lateral balance. Do you fly with anyone who's good at eyeballing for warps? From one of the front pictures, it looks like there is a chance the lower right wing has washout compared to the lower left wing. But it's hard to see for sure. When you look at the plane, push the ailerons into alignment with the wing. They make it hard to see a warp when they're not lined up.

Looking hard at the gear, there is a suggestion of both wheels aiming at bit to the right. As Bruce has already said, there are a lot of other things to eliminate first. But rigid gear on those "tall" suckers will accentuate misalignment. I usually take my models out in the driveway and "free roll" them to see how they do on a smooth, clean, level surface. That'll tell a lot about how the wheels alignment affects the takeoff roll. Keep in mind that it really doesn't play a big part after the prop has some purchase on the air and the plane's got a bit of speed.

It takes awhile to get good at seeing twists. But it does sound like you've got one to find.
