i will definitely start a Journal. unfortunately it will not be until later this year. We do a lot of acrylic and model work [see attached]; however, nothing that holds water. we have done some very large acrylic piece's. Both sheet and machined. the pump seals are for a training aid for a nuclear power plant and is over 36" in diameter.
For liability reasons we always do what the manufacture recommends. so we do a lot of two part cements because that is what the manufactures spec. since I will be doing this for myself i will not have to worry about the lawyers. I will say the best thing we have at the shop is the 16'x16' horizontal panel saw the table is roller ball and the saw is on a powered gantry. comes in handy for ripping down big thick sheets. I plan on doing as many videos as i can....

A pattern for a 6 part bayonet flange. I know that does not help much. I need to find some pictures of the finished acrylic flanges with o-rings and bonded in place.

That would be great, because I have no idea what you just said

My dad had One in his cabinet shop years ago. Mostly to cut big counter tops, it looked much like a dewalt miter box saw only room size. Nice to have access to big tools. The best way to fab big things is with big tools.
Do you guys aneal the plastic in large ovens?
And then bake the 2 part solvent bonded parts?
Manf. also recommends this process along with degassing the 2 part mixture, another pain in the rear step requiring a vacuum pump and vacuum bell.

I do have these tools but dont use them much for bonding acrylic. And I have only a standard used kitchen oven setup for doing small plastic forming. I keep it stored in the shed and pull it out and plug it in when I need it!

Fun stuff to mess around with and learn from

I would guess your dslr camera lens mounts to the body with a bayonet type mount. Same concept only out of plastic. Or like a 1/4 turn lid on a container to open it or close it.
