$20 power slotter for my lathe!

It does cut steel but it is really hard to keep the carriage feed slow and steady enough as (at least with my lathe) it is not possible to use power feed without the spindle turning.

John,

This comment set me to thinking. I also have a 12 X 36 lathe similar to yours. It would be possible to replace the drive shaft for the carriage with a longer one and add separate power feed on the right end of the lathe. From the looks of mine a length of keyed shafting of the proper diameter extending through the bearing block would be fairly easy to do. An alternative  would be to shorten the existing shaft and add an extension similar to this sketch.

John Hill:
That should work Joe.  I was thinking of drilling and taping the end of the shaft so I could screw some sort of drive in.

John, I've gotten a couple of windshield wiper motors from a surplus center listed on the internet as just that, for few bucks, and any one of them would make a good power feed.  I've also used a 9/16ths socket on my drill/driver to put power feed on the top slide, you could drill and tap the lead screw for a bolt and use that method, and there is no shortage of old drill/drivers which could become permanent fixtures on machines for power variable feed.  Don't forget for indexing, one can always use a strip of card stock, around a round piece of plywood, center drilled, and mounted on a drill press table, having used the dropping vertical parallels to put lines on the card stock and drilling holes in a piece of stock attached to the plywood, to index odd numbers and primes.  It looks like you should be cutting gears for a while :lol: good job on the milling column for your lathe. mad jack

John Hill:
Mad Jack,  the wiper motor is a good idea and just so happen to have a few of those!  (Off topic, one less than I had as someone I know was lamenting the problems he was having fitting wipers to his Lancia Stratos and what he really needed was a complete set from an Austin Maxi (c1970), he was surely beamed with joy when I pulled a complete set out from under my bench!)

Back on topic, I am thinking of fitting the drive to a change gear that I can put in place when I need it, that would drive via the lower gear box and prevent this old duffer starting the lathe with the auxilary drive in place!
