Dremel drill press - a micro mill for plastic 80% lowers?

[uncle harry]

If you can get lucky at a rummage sale or other event you might score a Fordam flexible-shaft grinder, polisher, etc., etc. The Fordam flexible shaft can be direct driven by the universal motor or on some models it can be attached to a speed reducer "port" for slower speed. They make ( & have made) a hand-held spindle tool much like a Dremel but very precisely made. They also make a drill press stand. Another attachment offered is a dental drill-like hand piece which has obvious advantages for free-hand work. I am one of those lucky guys who scored an older unit with a foot-operated speed control and 2 of the dental pieces, 2 "Spindles" and 2 polishing heads. If you are sitting down as you read this, I paid $35 for all but 1 spindle. (I had to tell someone !)

How 'bout this one?

Not inexpensive at $1355, though...

Or this one, even smaller:

I picked up an EP plastic blem 80% lower for $35, wondering what's the best way to finish it. I live in an RV, so even a standard drill press or a mini-mill is too big. I've been looking @ the 12V Dremel http://www.dremel.com/en-us/Tools/Pages/ToolDetail.aspx?pid=8220 with the drill press attachment:

I think this will allow me to drill the FCS holes and slowly drill the top of the receiver out. As the Dremel can be used as a wood router, I am curious to know if it will work as a slow mill on plastic. Perhaps inaccurate, but I'm curious if it can be done. Some folks apparently use a Dremel by hand to complete EP lowers, so a drill press attachment might be a step up.

I have a Dremel 110 V AC unit. It can be used as router but I never used it to route anything yet. I have no experience using mine in a drill press setup. Good luck

The flexable shafts are really nice but it has been my experience that you can't work them to hard or they will over heat and burn through the outer jacket. Had a Fordham do that before.

I was actually looking at the press today. I like the cordless tool but the press attachment is mostly plastic and very flimsy. Not sure at all this would be a fit for even very light milling.

With all the legal hullabaloo over the BATFE raid on EP Armory, I'm going to hold off on this project.

In any case, given what I saw of the dremel drill press, you would be better off trying to do it free hand.

With the price of finished lowers as low as 45 for a non plastic finish blem, I see no reason to take the time to complete a 80 percent lower. The only reason would be that you have the time and equipment to do it and do not have to spent funds obtaining equipment. The second you do not want to deal with a dealer or the BTAF.
I do realize that converting a 80 percent lower to a function lower may give one a sense of accomplishment. Good luck
