Slow speed adapter for Delta DP-220

[ksierens]

I finally got around to making a slow speed adapter for my Delta DP-220. I found the pulley on eBay, and made the rest, here are some pictures. Next is a table lifting device, already have it designed =)

Very nice work!

Did you keep your Unimat?

Very nice, it looks like the drill came with that feature. I want to do something similar with my DP220 but my counter balance for the table already sits on top of the post. I'll have to put on my thinking cap

Yes Shawn, Delta did offer a slow speed adapter for it, pretty much like Craftsman drill presses, just hard to find, and easy to make.

Here is a picture of the table raiser I am going to make as a weldment. The gears are about $15 through Amazon (die cast) and the 1/2x10 acme lead screw and nut from eBay for $25. I had to buy the tubing from Speedy Metal, which is 4 miles from my house, and I have enough scrapes for the rest! I am going to make a 3/4" boring bar holder for my lathe first though.



Here is a picture of a unit I have seen on the net that I modeled it after.

Steve, yes I don't think I will ever sell the Unimat. I had always wanted one since I was a kid, and it is very useful for small work.

I have never had a need to, but if I did, I can always use it without the slow speed adapter.

Nice work on that slow speed adapter. i just recently picked up a nice dp-220 with the slow speed gearing. I will have to take a good look at it tomorrow and compare it to yours.

Bringing one back from the dead: How did your slow speed adapter work long term? Any issues with it? did you make any dimensions of the parts you built?
