Just curious. Where are you getting the acrylic for this project? They should certainly have solvent....

Yes, they do but they're charging $42 for a can of weldon #3! And they don't have either of #16 or #40, which I'd prefer given this is my first such project.

You want to use 3. 16 is just sloppy and 40 is a 2 part mix that it a hassle to work with. A bit of practice and #2 or 3 will be fine.
A small can of 3 should be a couple of bucks.

3 is fast like Methylene Chloride. Use 4 instead to give you more time. 40 is good for not so perfect joints but has a short shelf life. 40 works well for pvc to acrylic. 16 sucks in most cases.

Maybe a good idea at this time of year to read the warnings listed on this link. I'm thinking there may be reduced ventilation in your work area due to heating your space.

not to go off topic but..

The link suggests annealing to prevent prevent crazing, how is that done with acrylic?
