This whole dilemma of sharpening at home has been a long process for me. I didn't want to end up like my bro the real machinist with boat loads of low cost HSS end mills filling drawers and still not having a sharp mill when I needed one. And by the views threads like this get, I'm not alone.

So after looking at all the surface grinder type setups and more than the cost I got scared of trying rebuild another machine much less the learning curve, electrical needs and space. As everything in my price range probably needed some serious work.

I guess I should fess up and say I've done kinda like John but went the Deckel knockoff Chinese route.

As with most things I don't understand as well as I should, it's been quite a learning experience. The original machine like in the pic was not really designed to do endmills(even though it claims to). It was designed to do single lip engravers. And I'll admit I had no real clue what a single lip engraver was. I just looked at the chuck head and thought it must be able to grind anything.....wrong. I tried to ask questions like my bottom line was it needed to be able to chuck up 3/4" end mills which when was expressed as .750 they said it would. Wrong. The one in the ad has Deckel style collets and are limited in size and can only chuck up 18mm, and it needed 19mm to do a 3/4" end mill...doh! Communication can get garbled no matter the native language. I've been lucky these folks truly want to work with me so it's been a long winding trail but we've managed to come to a working deal.

eBay has gotten to be such a tricky place to purchase exactly what I think I want because my experience is so limited. I let price and shipping lead me on and had one like the pic delivered. The first major problem was it weighs 100lbs +. It was double boxed with some styrofoam but was truly a miracle it wasn't destroyed. But another go around with UPS and it would have been more serious damage than a dented knob and a bent adjuster it received. The styrofoam was literally turned to powder in the bottom of the box. When I finally got it unpacked without destroying the box there was 2 major shocks. It runs on 220v 50hz so it had like a mini 3 prong dryer plug on it. Then I looked through the collets and the biggest was a 12mm. Couldn't chuck up even a 1/2" endmill.

When all was said and done I was able drive it down to their warehouse and swap it for the new and improved model that uses R8 collets(! yay, score) and 110v. It also came with a stone and a diamond wheel and they are even going to send me the head for doing the flutes. So far I've been able to rescue my original set of off brand end mills and am starting in on the misc end mills I got with the old Rf-30
