[pmrid (Peter)]

For those still following this thread, I have reached a stopping point. I cannot find another tweak I can make until the rollers arrive - now promised for next week. Heaven knows where they came from. China I suppose.

I have made a template for the pier base (see picture) and cut away a section of the plastic flooring for it. As you can see from the image attached, putting a pier on top of this would be a big mistake.

The pier base has 16mm holes - probably to allow a bit of wiggle room - and I have drilled out 12mm holes for Dyna Bolts. But these can wait until I have installed rollers and cut off the roof from the base.

But all in all, it is a kind of progress. It just isn’t as rapid as I would have liked.
