It is amazing what you can do with a benchvise and acetone.


I am refitting the DC system on our trailer at work. I needed some terminal posts for battery recharging. I searched around town but couldn't find anything. I resolved to make my own. We have a scroll saw, plexiglass (Lexan), acetone, drill press, a benchvise, and some #10-24 stainless steel screws.

I now have two terminal posts. Not bad work for never having done stuff like that before. The acetone was used as a bonding agent for the plastic and it worked great. The bond is even optically clear. I'll have to keep that in mind for future projects.

The trick with sawing plexiglass is that you have to have move the saw S-L-O-W. But not too slow. Too slow and the plastic chips and cracks. Too fast and the plastic will melt and bond behind your cut. And you can't loiter in one place to reposition either or the plastic will melt and then bond behind your cut. Tricky.

When gluing, you should not use too much pressure as the plastic will crack.

By the way... acetone can be nasty. Wear nitrile (not latex) gloves. And it only takes a drop as capillary action when pressure is applied will get the rest of the coverage you need.
