After I introduced myself a few weeks ago... and the consensus was "just jump in and start making some pens"... I have done so. I've made three so far. My wife loves them... whereas I look at them and say, "I could have done this [insert appropriate part, transition, etc.] better." I'm sure I'll always say that no matter how long I make 'em.
Anyway, I've been making pens with 7mm tubes. Yesterday I attempted turning a larger pen with a 10mm tube. This was done using a 7mm mandrel. When I took the wood off the mandrel... the tube was off center in relation to the wood. Looking at the end of the wood I would normally expect to see two concentric circles. In this case, the tube was off to one side - so one part of the wood was quite thin and the opposite side was rather thick. Looks to me like when I put everything on the mandrel - I locked it down with part of the tube against the mandrel, but the rest of the tube was not against the mandrel, nor was it centered around the mandrel.
The bushings that came with the kit were 7mm... I assumed I could turn it on this mandrel and not have to get a 10mm mandrel.
So, what should I do in the future to do it right? Seems like I need to center the 10mm over the 7mm mandrel - but I don't know the secret. Well, besides holding my tongue just so...
Thanks,
