I think Ballendo was referring to using a laminator for TT rather than for applying photoresist film. Les

If we aren t careful we could end up with a holy war here. I couldn t get TT to work and photo etching works well for me. For others the opposite is true.

Hi Mike, It is probably a bad idea to use ordinary acetate. You can get laser safe acetate but the results are usually lacking in contrast. As you say, lasers

... Each tube is actually a separate lamp with its own ballast and starter. The lamps were on sale at the time with each costing less than a single UV tube.
