Well two things. The drill press at my parents is 3 phase. He wants to strap a single phase motor on it and I keep telling him that 3 phase motor is superior. He doesnt want to spend a lot of money. I need to find him a cheap VFD to power a 1 hp motor. I thought the motor was 2 hp but apparently its 1 hp, but not quite certain on that.
Other problem is that he and my uncle had the bright idea of using the Makita compound mita saw to cut up firewood. A cast piece of aluminum that holds the spring snapped off. Need to fix it, perhaps some of that Alumaloy stuff they advertise on TV with? Dont want to buy 65$ worth, just a small stick. Either that or have some one weld it up. None of us have a TIG setup.

A VFD would be a waste on a drill press,IMHO.

I would definitely go with a VFD on that 3ph drill press. Any nice tool(s) would be a waste in IOWOLF's shop.

3ph motors are much smoother. That must be a really nice drill press.

Well, its the Buffalo 18" drill press I bought used for 175$ Got a tapping head with it too.
It is good in my book atleast. Another option is a doityourself RPC or a static phase converter.

1hp VFD's used to be pretty cheap on eBay. I haven't checked for a while though.

Yeah, those cheap Makitas! http://bbs.homeshopmachinist.net//biggrin.gif

How many pieces of the Alumaloy do ya need?

Ken, just a single small piece. Wont get a chance to use it though til spring. I guess a couple of inches, I know, will get too hot to hold, I'll just use some vise grips.

The nice part about using a VFD is variable speed. No belt changes. So when you are gonna drill a 1" hole you can speed it up abit for a small pilot drill then slow it way down for the 1" bit, all with a twist of a potentiometer or a tap of a button. JRouche

Ebay is probably the cheapest possibility, if you want to deal with Ebay.

There have been several surplus VFD dealers mentioned at various times in this forum, if you want to search the archives. www.dealerselectric.com (http://www.dealerselectric.com) and www.vfds.com (http://www.vfds.com) are two that come to mind.
