Hi Joe
If you have a vacuum pump you could knock up a degassing pot, i use an old pressure cooker.

Hot air gun across surface would usually deal with any bubbles.

Ready to pour! I made some little brackets to hold the mdf in place sealed both sides with silicone so hopefully no leaks! and heat gun and Vaseline at the ready!

Best of luck, looks like you've got everything prepared though so I'm sure it'll go fine.

careful with the heat gun joe you can easily cause hot spots which harden at different rate. Only a quick flash is needed and only if really needed. Few air pockets won't hurt anything.

Not quite sure what the vasoline is for thou.?

Vaselines for the same as heat gun apparently "Some like it Hot!"

Cheers Dean, I will take it easy on the heat. The Vaseline was for the mdf sides to act as a release agent... I think Clive suggested it?

This is why you want slow cure epoxy - this a time lapse- the movement is barely perceivable in real time. well it's done. Now we wait...

Great stuff especially the time lapse video. It might be worth keeping the bridge between the 2 rails in place during initial setting up if you need a datum to DTI off to align the gantry Y rails - depending on the gantry rail design you've decided on
