Removing rubbery potting compound

Thanks! I've lost track of how long the laser tube is. If you can thread dental floss along the length of the tube you can saw the tube out with the floss. Interesting thought. At least that's something I have. I have a feeling it is going to be something along those lines.

But where this is needed is to remove the stuff surrounding a glass laser tube - about 6 inches in length and a space of 2 or 3 mm between the tube and the cylinder it's in. Both the cylinder and tube need to come out undamaged. How about using a thin blade from a coping saw? Once you manage to slip it all the way through the length of the cylinder it should work fairly well. I don't think it'd damage the glass either. My coping saw blades are only 6 inches long, I doubt they come any longer as only intended for small light work. After drilling a pilot hole I would try one of these sort of wire saws http://www.ecamo.co.uk/product/webte...e-saw/265.html fed through and then bodge fixed in a 12 inch hacksaw frame for rigidity. Or straightened out bit of heater element wire Or a guitar string, the rough coily type. |
