Very nice work! Doesn't have to pretty, that's for sure. I almost did the exact thing for my 7500 14" Logan chucker. With time and patience, I did ultimately luck out and find a steady rest AND follow rest AND tail stock AND a 65xx saddle. At the end of the day I paid more for those parts than I did for the lathe itself.
Thankfully, I think I did okay on the lathe itself so I'm not too sore about it. Around here, these sorts of machines are not a dime a dozen like they are in some parts of the country. So sometimes buying whatever you can and being patient to buy the missing parts OR making the parts yourself I think makes sense.
