The following parts were purchased from www.surpluscenter.com

Qty Part# Description
(2) 1-209-28-4 pillow block brg
(2) 1-3422m flexible coupling
(1) 1-3422x rubber insert for coup
(1) 11-2102 DC speed control
(1) 11-2102-r43 resistor for spd cont
(1) 11-2102-h heat sink for spd cont

I used a DC motor off of an old nc mill and bought a gear box off of ebay. You need a 5:1 ratio gear box if you are using a dc speed control if not you may want a 7:1 for lower rpm for larger diameter cutters. 1725 rpm motor with 5:1 will give you about 350 rpm cutter speed.

You could use 13-206-5-56c-de gear box and 10-2430 motor from surplus center if you can't find something cheap on ebay.

Arbor to hold 1.250 shank endmill cutter was made on lathe I can give you dimensions if you decide to build.

Bottom plate is 1/2 thick by 18 x 24 inches, has box tubing underneath for reinforcement, is not stiff enough without it.

Milling table is Shars brand, 4" swivel milling machine vise both bought local, about 190.00 for both. V vise jaw was made out of piece of 2X2 aluminum.

Arbor centerline from table was 9.937" with milling table and vise I used.

If you decide to build be happy to help with any other info.

I am going to be using my lathe as my tubing notcher later this year hopefully. I am going to hold the 2" annular cutter in the three jaw chuck and then make a mount to hold the tubing in the carriage. This way I can use the power feed to evenly feed the tubing in to the cutter. Should help with cutter life.

That is exactly what I want to do. I have been notching in the vertical mill but it would be really nice to use the power feed of the lathe. I am going to try and work on that setup when I get some of the other projects out of the shop in the next month.
