I sure do love it when the simple solution works. <grin>

Yes, a mig tip is intended to smoothly pass the indicated wire diameter and
so has a larger ID. 0.035 mig tip = 0.042" sounds right to me though I don't
have the chart handy. A 0.045 mib tip is something like 0.055" +/- (from my
shakey mimory an accurate correction will be appreciated) If I recall
correctly somebody either posted a chard of mig tip IDs to the list or has
it on a web site.

I've gone the "flexible" supply tube and found it was much easier to just
measure carefully and recheck alignment, square, etc. before drilling.

Actually, opening the doors seemed to be the key but lengthening the
straight section before the bend might make a significant difference.

Ya see? I most certainly can be wrong! <grin>

Once again, you're very welcome. It was an excellent exercise in list type
problem solving. You defined the problem in good detail, gave a complete
discription of the device and it's expected and actual operating parameters.
A little fine detailing and the solution was easy.

I married a Yooper and so am conditionally allowed the term. Just so long as
I don't attempt a Yooper accent!

If you'd said you only had one project I wouldn't have believed you. <grin>
