So, time has come to build the base.
The most common plastic I was able to find was HDPE cutting board:
I cut 2 pieces:
5.5cm x 7cm and 7cm x 9cm:
Stack and clamp for drilling: with the L-bracket:
On the underside I needed to make a countersink for the M8 x 30 bolt head:
It should end up looking like this from the glass side (bottom):
Let the HDPE and glass sandwich sit for 3~4 days without disturbing it. I know the silicone will not stick too well to HDPE, but it is only for testing. I might have to remake the build base.
Time to drill the L-bracket for the two M8 bolts and the M3 bolts that will hold the build base to the THK Linear block:
I used M3 x 8mm slot bolts. I could not readily find Inbus (Allen head) M3. All the local hardware shops stock from M4 up.
The end result will look like this:
Seems to be stuck well, but the question is : Will it come undone under the forces needed to lift the cured resin off the VAT?
We shall see.
