My MOST important lesson from the Erector Set Motor was "In running pinch points". Getting my finger stuck in the gears really hurt, but I didn't loose anything. Carl.

Hi Gang: For a feed rate, count the turns you use by hand. One second per turn perhaps? So 60 rpm might be a good starting point. Although the cuts are so short on the Unimat I never set up the

The Erector motor can also be easily geared to various speeds and shifted into neutral or reverse. The Erector was my favorite toy when I was a kid back in the 1950s and learned a lot from it. I still

John, I use 24volt DC motors for my Unimat. I know I have said this before, but the convenience of variable speed, reversing,and Quiet Operation are a big plus! Just dial your infinite speed-and away

Further to my earlier message, I looked at feeds on the 11in Maximat.? Based on what I have done for finer jobs, maybe .002 - .003" would be good for a Unimat.? Any opinions about feed rates?? Now

For Carl and all of us, we will never need any huge motor gearset shaft to turn our Unimat shafts.? So with these Surplus gear motors, what rpm do we want?? Someone more practiced than me can tell

Hi Gang: Surplus Center has a range of DC gear motors. The plus with DC it is easy to build a variable speed control.

For something that you can actually buy, try this Ebay item: 226166478327 It is $7.69 + $3.00 shipping. We don't need to analyze torque.? If it works, fine.? If it breaks, get something else. On

The Wayback site, which I support, can be a little hit or miss on how much of a site is archived. And, sadly, I haven't found where any ISP provided pages have been archived. Sometimes gold, sometimes

I do understand. I now consider that anything released in an email or web post, most places, may as well be considered "Out in the wild." When another regional group I'm a member of moved to

I was lucky to find this motor with a reduction gearbox. The slowest rev is 19 rpm. and the fastest is faster than by hand. The end of the lead screw is like a flat bladed screwdriver. So i just cut a

Hi Carl, This little set-up has a lot of possibilities. Something fun to mess around with and a sight better than a $200+ Unimat power feed unit! Rick

Hi Mr. Key: I did this for my Unimat DB. Only I used the flexible shaft and a 8mm socket. That way I could drive the cross feed too. Also if you add a second shaft to the motor you can have two

Works better than I had hoped for..

I just got done cobbling together a cheap power feed unit for my Unimat 3. I used nothing more than an Erector Set motor and 2 of the pulleys that come with most sets. The 1 to 1 pulley ratio actually

They didn't get everything. And stuff they had a few years ago is gone here lately..I was trying to archive a bunch of the metalworking stuff myself, but three hard drive crashes in the past decade or

Ah, groups.io hides email addresses, truncating them and adding three dots (…) So my last message probably won’t make any sense at all. Sorry. I was trying to explain the email address renaming

Not sure what the problem is here, all posts to and from the forum go through groups.io, so the ’ *via groups.io* ’ bit is quite normal. If for example your email address is abc@... then

Amen, Brother! Though I do wish some of the info that was once stored on the internet was better archived.? Bill in OKC? William R. Meyers, MSgt, USAF(Ret.) Aphorisms to live by:Good judgement comes
