Smithy 1220 4 jaw independent chuck adapter?

[Tincamp67]

I’ve pondered a 4 jaw for my smithy as well, but don’t want to drop the money on a new one. It’s actually a capable lathe. It’s more rigid than my SB 9, so I use it for heavier stuff, or things that require a larger pass through.

Lets say the 4 jaw was free so its worth a plate attempt.
Im on the hunt for a chunk of steel. Been on the look out for a older treadmill curb side in hopes it had a steel “flywheel” big enough.

For my 4 jaw backplate I used an old barbell plate , it was a pain with the hard scale and hard spots . Would you consider a blank plate from Grizzly ? https://www.grizzly.com/products/gr...MI4LXVybbgggMVT1BHAR3RTwNAEAQYBSABEgIhy_D_BwE

If it ever comes back in stock …been waiting a while.
iirc it was close to $70 bucks shipped?
So what do I do
Spend $70 on material hours machining it possible mess it up or toss $70 into the tool piggy bank?

Free is always good. Just seems rare in a post COVID world. I keep my eyes and ears open for stuff but rarely stumble on anything.

Its been rare for sure , although it came from a group I have been swaping and giving stuff with for years. Also came into some nicer mics, dial indicators , test indicators , V blocks, gauge blocks , pins and a good amount of cutting tools I have yet to even sort through.
Only thing that seems hard to come by is lathes made in the last 50 years ! Everything is 70 plus years old and worn , lol.

I did come across a treadmill in hopes of a cast iron flywheel for more material but looks like its very thin where I need it?

Been on back order for some time and the 1.9” center hole leaves no material for the 4 chuck bolts?
