Re: Gluing polycarbonate?

Hi Terry,

Have you thought of using some RTV. Might be easy to experiment with if you have some scrap polycarbonate. Call FC plastics. I bet they will know what works.

Hi,

I "finally" got my little coil wound:

The new little winder and speed and torque controller work perfectly ;-))

About a thirty minute job, but the wire spool needs a bit of a tension take up cushion thing like those old 1960's tape drives had :o)) I could just "grab" the wire if anything went wrong and it gracefully stopped for the fix.

I did replace the counter switch with a magnetic security window alarm switch from Radio Shack.

I drilled a collar to fit the long 1/4 inch magnet and made a little holder for the enclosed reed switch. They only way to go there!!

I should replace the counter with one of these:

DK# Z186-ND needs no external power to count has a switch to reset so it is super simple. But what I got now works fine...

So the question is...  I have a polycarbonate tube and internal and caps:

What sort of glue will mate them??? I hear "super glue" reacts bad with water in polycarb to make it all frosty. Many things "don't stick". I am thinking epoxy or "gorilla glue". Rather not use anything that has a terrible smell since it is indoors...

I got the Envirotex Lite ready to go to coat it now. I made a little test thing and it looks great. Cool how a little "breath" or CO2 off a propane torch "boils" the bubbles out. I bet a little dry ice near by would work good too... It has zero to do with heat but is rather some odd chemical reaction with CO2 that breaks the bubbles.

Cheers,

Terry
