Mitre Saw Wheely-Stand Thing

I've had my mitre saw clamped to a folding workbench thingy (basically a cheaper version of the Black & Decker Workmate) for years. That was fine, but it was troublesome to shift around, and in my rather cramped little workshop I need to be able to shift things around so that they don't interfere with each other when I'm trying to use them.

So, I made this stand out of el-cheapo treated framing timber and some unexpectedly expensive locking castors. It doesn't look like much, but it's sold as a rock, and it gave me lots of practice at cutting mortice & tenon joints, bridle joints and lap joints.

We have bamboo growing in our garden, and I thought I'd use some as railings for the upper shelf, to stop things being pushed out the back or falling out the sides. Bamboo is good for that sort of use, as it's both thin and strong, and it will get stronger as it seasons. The down-side to it is that nature is distressingly imprecise in its sizing, and I had to do quite a bit of searching to get canes that were all within a size range that would fit my available drill holes.

As a side-effect of all this, I got my clamps a bit more organised and accessible. Next, I'll have to get a concrete pad under where the saw usually stands — at the moment it's sitting on various bits of wood spanning the rotten boards underneath, which isn't ideal.
