The Tom Morris type uses a insert glued into a tube, though, right? I thought that's what we were talking about.

We were, but Frank mentioned that he was asking about the square machined ones, and off we went.
Tom's problem was his preassembled joints. He employed workers to make these, and they glued them. I do not know his process. I decided to test them when one of my preassembled joints let go.
I took a preassembled joint, cut the cross fuse tube off about a half inch from the joint. then I cut a spiral groove in the tube at the joint down into the male part. I did this also with my glued joint. O om's, I was able to simply peel the tube off of the joint. The glue simply didn't adhere well at all. on my joint, I had to grind the tube off as there was no way I could peel it off. Yes, I know this is not the exact way the glue is loaded, but is indicative of how well the glue is adhering to the parent parts.
I do not know how Tom prepared his joints, if at all. I roughed up the surface on the tube ID, and the male part OD. They were then cleaned in 99% alcohol, and dried. JB Weld, steel type, was the glue that worked well. I mentioned this to Tom, and he immediately stopped doing pre glued joints. Bottom line is that Tom's will work fine, as long as the glue joint is prepared properly. His materials have proven to be fine. However, I have never liked those glue joints in my planes, and once a quality machinist was found, the new design was used since then.
