1. don’t use contact cement – it doesn’t have a rigid glue line but a flexible one. use yellow glue. spread on both sides – since it’s MDF, it’ll soak it in a little which is a good thing and will give you a good bond.

2. making cauls is easy – bottom line – you just need it to slope from the center to the sides, so that when the sides are clamped, it’ll bend and create pressure along the center as well.

3. I think your tool stand station will be more than adequate to hold the 2 sheets during glue up.

4. little trick – if you don’t want the 2 panels moving during glue up (glue can sometime be slippery and shift the panels sideways) rub some sand paper over the panel with the glue (just a little bit) the glass remnants will create enough friction to hold the panels together

and finally – if you need hand planes, cauls, or the likes – feel free to stop by ;)
