Southbend 9" lathe rebuild

[Commander]

Good progress Sid! So as a suggestion, why not spin the pulley up with the drive motor and then use that as a "makeshift lathe" to make sure the pulley is true? I have seen some youtubers do this and it seems to work well. Probably a little risky, but might be worth a shot. Should also make sanding it down to a smooth finish easy.

Commander. That's an option I am considering, I didn't really expect last night's bodge to work. I put one grub screw in it originally, I am thinking I may put another offset to the first and the key way which should stop any play on the shaft. A quick true up should then be enough. If my maths is right then running it direct is going to mean running the motor pretty slow to get the desired spindle speed so I suspect that job 1 is to create real pulleys for a countershaft. I have also realised that it's not possible for me to run it as a rear drive due to the casting of the spindle headstock - so undermount it is, and that puts me into spliced belt territory (and also means I need to think about a drip tray more carefully).

It is however good to be back to making progress after a winter hibernate.

Nice work Sid, it's good to see old machines brought back to life.

A little update to detail the latest highs and lows...

First the dull stuff... I didnt get a saddle lock with the lathe when I picked it up, ebay failed to net me an original in the UK - and the US sellers all seemed to want more in postage than its worth. Lots of digging finally found me a picture with dimensions on the web, so an hour with a hack saw and a grinder later....

Its a simple part, but its a pain in the ass to measure because of where it sits...

please forgive the crime that is the socket as a spacer (the screw is too long and I was too lazy to cut it down) - especially since it is a metr-inch one and as such the spawn of satan!

In much more exciting news, I have had a few goodies arrive. Pillow blocks for the soon to be made (hopefully) countershaft..

and the highlight....

Some adjustments will be needed and I suspect they will not be my last set of tools - but they are HSS and they are my first!

Quick drop in for a couple more photos... This time control panel for the VFD and a display for the tacho.

There are a couple more bits to arrive and get fitted - reversing switch,the arduino that will be the brains of the tacho with the readout on the LCD that is there, and some push buttons to interact with that. If I ever get onto putting DRO on the lathe then it can double up to displaying the values on there too.

I think if I get a chance then Sunday may be the day to get the motor mounted temporarily under the desk and see if I can get a belt the right length. Altho I may not get to run it as the control panel looks a state so I may also give that a coat of paint

Sid.
