Resurface the ShopBot

[andrewadare]

The MDF wasteboard is pretty well used up.

Before replacing, Jacob would like to get the ShopBot moved out from the wall 18-24".

We'll need to purchase a 4' x 8' MDF sheet, either 1/2" or 3/4".

The topmost board is bowed up from the table. You can flex it down by hand. This is a major problem for projects requiring even remotely precise work in the z coordinate.

Replacing the uppermost "patch" layer is quick and cheap, but we ought to consider spending the time and money to replace the underlying plywood/MDF stack.

I propose that we schedule a refurbish date in the next few weeks or months. With a few volunteers, it should go quickly. Should be a two-stage process.

Prep:

• acquire 3/4" MDF, plywood, adhesive, and fasteners
• glue up layers on a large flat surface and clamp/weight the assembly

Replacement:

• remove old surface and dispose
• clean up machine and surrounding area
• reposition machine
• mount new surface
• mow it flat/true

This was done in Summer of 2020, however it may need to be flattened again after the move this week.
