To expound a bit on Adrian Page's thread "how to focus", this is my attempt to make focusing without a moving table a little easier.
With a non-moving table, my limits so far have been: a max. material height of 5/8" with the supplied lens tube, and the need for lots of shimming to focus tall objects or parts held in clamps when using my 'auxiliary' table, which is simply a piece of 5/8" thick wood about 3x4' that so far works well. To help with these issues I had Triumph send me another factory-length tube, plus had them make 2 longer tubes. And I just finished cutting an inch off my original tube so the collar just bottoms out on the head, which now gives me a 1-5/8" max material height. This is great because I'll soon be needing to engrave 2x4's and other 2x lumber in the thing. And with the longer tubes and my aux. table I can now accommodate parts up to around 8" tall, and should be able to focus without messing with shims.
Not sure how the long tubes will work but I'll be finding out shortly, I have 'tall' work for the machine today!
