Edit: I did this and it worked even better than I expected. two extrusions, received precision cut to 500mm -- it made the bed and makerslide square to each other by tapping the extrusion and using an existing hole in the stock Shapeoko 2 bracket!! The bed was trivial to level as well and didn't need any shims.
Has anyone tried using this part for a Shapeoko 2 bed?
Misumi HFSQN4-15250-500 it is a single extrusion 15mm x 250mm x 500mm. it has 8 x 8mm T-slots on the "top" side and 7 x 6mm T-slots on the bottom and 1 x 6mm T-slot on each of the edges. 2 of them would cover the entire bed nicely I believe.
Although they are not cheap they beat all the other options I researched, 2 pieces, all in under $60 usd (plus shipping)
The 15x250 extrusion is available in longer lengths (1000mm and longer) for you upgraded shapeoko 2 guys too.
So has anyone else done this. I put my order in but have not received the material. I will probably back it with solid MDF, plywood, or diagonal cross braces to make it more rigid/level under clamping pressure. Any thoughts? concerns? things i need to consider?
