A real beauty LBD!

I know that your laser method keeps the tolerances up to your 6-Sigma standards, but is there any allowances for tweaking the fence angle if (ahem) the saw miter slots are not quite parallel to the blade?

I was going to also say that maybe you should use a harder/slicker type material for the runners, but given the saw size and use, plus all the consumable inserts, that sled will last a long time until the termites arrive.

Big plus is the ability to flat-pack ship the thing. You could send a demo to WoodPeckers with a royalty contract. They'd lawyer up and find a way to void your claim and put one out, anodized red of course, for a tidy profit.

As to dropping tools and hardware, I often find it best to just let it go. Eventually the hidey-holes will fill and all your dropped stuff will be easy to find just cowering on the floor below your feet.

Thought and planning into the construction is A1 👍
