So I got one of those Estes fin alignment tools, and I am struggling with what should be a simple thing.
To use it you insert one of the smallest tubes (13mm) into the stand, and insert the standard A/B/C (18mm) and then D (24mm) motor tube blanks over to center larger tubes onto the tool.
That sounds easy, but I cannot get the smallest tube outer diameter to fit into the inner diameter of the A/B/C size tube. The issue doesn't seem to be one of a bad "lead in" to the ID of the A/B/C size tube. The ID of the A/B/C size tube is either too small or the OD of the 13mm is too large. They just don't fit - the overlap seems to be a few mm. I could sand the heck out of OD of the small 13mm tube till it fits inside the other one, but you really shouldn't need to do that.
Any ideas whats up here? Any suggestions?
