Brian - I would keep the original drive assembly if I had it and use the VFD to power it and add the variable speed capability. That way you have the best of both worlds. Plus I like to keep the

Louis Can you show me a picture of the box you use for the VFD and how you vent it. Do you use a filter over the box . Also where Can i get a the boxes. I am looking for a 12"x12"x12" box with a full

Hello Louis, I just wanted to say thank you for taking the time to share your experience and thoughts on the VFD's and what you've used. Your information really helped me out, and I'll put it to

The 405 should have 20 DP gears, IIRC. But, you should measure the OD and tooth count of your gears to be sure. allan -- "well, I stand up next to a mountain- and I chop it down with the edge of my

I may be incorrect on Boxford. I think the 22 DP is Myford. Here is a link to gears.

Kit, I've got the 3D printer files from Thingiverse contributor dsell. The info on the gears he designed are as follows: 14.5 PA; 18 DP; 3/8" thick; 1/8" key; 9/16" hole. If you can find the same info

I'd suggest you clean it up and add a spindle sensor and X/Z drives and use LinuxCNC or MACH to automate it. You can still do manual operations with a CNC controller. If you don't want full

I ay be wrong on the Boxford. I think its Myford. here is a

I used to have a 405. first thing to know is that the gearing is 20 DP. Later workshops, 415 and on are 18 DP (except for the 415 twin gears, which you the 405 does not have). When I got my 405, it

Just bought my first South Bend lathe. It is marked South Bend Workshop Precision 9” with a 3’ bed. I am told it is a 405, manufactured in 1935. Unfortunately it is missing the reversing stud and

Thanks Louis

Brian, Based on my experience with repowering machines over the past 20 years and having half a dozen machines here running vfd's, here's my thoughts. If you want or need variable speed, a VFD is the

Nice - sounds like you are hooked up! That's what I did in my previous shop - ran a nice line to a sub panel for running a jumbo melting kiln, and some CNC equipment. I think we'll be moving in

Best thing I did years ago was to pull 240 volts from the house main breaker to a 125 AMP sub panel in the garage. 240 single phase runs the Rotary Phase Converter. The RPC runs a Bridgeport, 13"

Hadn't thought of using mig wire. Might give that a try. I just use nylon stranded cord rated 170 lb. Can't remember where I bought it. Either Lowes, HD or Ace Hdwr.

Hi Jim, Thanks so much for the information which is helping me to understand all the nuances associated with my new to me 9" 480 YN. I would be very interested in hearing more about the spare parts

According to my data, the Model 480 is a Series N QCGB based on the model 80. but with horizontal drive. 480 9" N QCGB See 1930 Model 80 but with horizontal drive The attached is from the 1930

Hi folks! I am new to this group. I will be picking up my 9" 480 YN next Saturday. As I have been doing my research, I have been stumped on not finding any information on what the 480 or the N

For your ribbed belts what do you use for lacing? I used MIG wire and it's only now after 10 years or so starting to break where it's flexing or work hardened. One of these days I will need to lace

Just want to add the option of belt lacing to the discussion. I run both leather and serpentine belts on different machines in my shop and most are laced. That goes both for the leather and serpentine
