OK Dave - I am sharing.

Still working on ways to improve the finished cut quality of acrylic parts. Having solved the problem with striations on the cut edge my next problem was with reflections from the table or work supports overheating or damaging the finish on the reverse of the work. These reflections were traveling about 50 - 80 mm beyond the work and although they were well out of focus still contained enough energy to cause damage. All metals reflect at 10600nm but glass doesn't so a simple solution was achieved by making a wooden containing box with glass base then filling the box with aluminum, concertina bent, venetian blind slats (on end) as the work support. This really does work so well and the money I have saved over buying ready made honeycomb cutting bed material can all be spent on Beer  ;) (Dave, Sam & Russ would approve of this, I thought).

You are a "Master of Improvisation" Tweak.
Glad to see you're keeping the financial priorities in order.
Set em' up barkeep, this rounds on me.

Indeed! Efficient, inventive, and the parts look "clean as a whistle".

Nice work, my friend-

If your buying, Russ, I'll take two. Looks like your really getting the hang of that laser, Tweakie.

OK Sam,
One more round and a six pack to go.
But first, you have to update this:

With all the cool stuff you come up with Tweak, I think to myself.."Ya know, why should I even bother"  ;D
Your inspirational, and demoralizing, all at the same time.  :D
As long as you can see that gray paint on your machine, there's room for more gizmos and gadgets. We sure do enjoy looking at all the stuff you come up with.

Think I have done it this time fellas. The temperature controller arrived yesterday, it's bigger than I had originally thought and gray paint or not, I can't find anywhere to fit it.  :'(
I haven't found the right thermocouple yet so I may try my hand at making one (if I can find my spot welder which I don't think I have used in the last 10 years).
