RE: O.S. .61 FX Engines
Cool...having previous experience w/ such tool should make it much easier.
Actually, since you are removing such a small amount of material in each "pass", and the fact that it's Brass, makes it unnecessary to hold the sleeve or tool in a fixture. In fact, you are moving the tool and the work piece almost constantly so...
I just hold the sleeve in my left hand and the Dremel in my right, (I'm right handed ) and steady my forearms on the table...
Anyway...that's the way I do it...but hey,whatever works best for you...[8D][sm=thumbup.gif]
