Acrylic Router Bits

[Chad]

well, my router table has a very crappy miter guide.. So I cannot make 100% 90 degree cuts.. I tried to make a coping sled, but it suffers from the same sloppiness in the miter slot. Was wondering if someone had a good jig for 90 degree angles.

Ok, I have one problem, one seam has a large bubble.. It was not there when I left it last night but it developed over night I guess. I have read that I can drill a small hole and squeeze in weldon 16. Has anyone tried that? Or should I just install a gusset? Also, anyone know where to get weldon 40?

DIY router table? So is mine. Maybe take a look at T-tracks from Busy-Bee and build your own or install a store bought fence/miter slide. Also start your cutting work using stock with a 90deg angle present. By the way, I aswell would use a table saw for cutting stock and the router for other stuff like template work, triming, hole cutting and shaping.

Weldon 16 is a thick glue and would work for filling gaps

What did you use to glue the joint? I sand it lightly if required, clean it with isopropyl alcohol then use straight methylene chloride to weld joints

I used weldon #4. I have some pretty nice seams for my first time. Out of the four sides of the sump I have together, 3 have only a few tiny, it bitty bubbles and most of it is crystal clear perfect seam. However, my last seam of the day, developed a bubble that looks like it goes all the way through. It is on the top portion of the sump, so maybe not critical but would like it fixed.

The router table is not DIY. But its miter slot is not standard. So I cannot use some of the regular miter stuff that is available. I have thought about making a new miter slot and putting in a standard T track, but it is getting a bit expensive for something I was DIY'ing *the sump* to save money on. At this point it would have been less to get it made by someone else

I wouldn't worry about a bubble on the top seam. If it was on the bottom 16 or 40 works to fix it. With 40 it is possible to place a thick bead over the joint similar to silicon with a chalking gun.
