All I can say is lotsa luck as far as finding old iron that's not worn out and is not thousands of miles away. I looked for a heavy 10 for several years. They were usually out of state with shipping being cost prohibitive and one doesn't know the condition unless they can go there and thoroughly check out each one. I bought a Clausing 4900 from a school several hundred miles away and had it shipped, which turned out to be a disaster. The bed was worn out, broken gear teeth and broken compound. Parts missing. I was getting quotes for thousands to regrind the flame hardened bed. Accessories like steady rests are impossible to find. Just because the old iron were grand machines 50-70 years ago, doesn't mean they were well maintained or they don't have a lot of hours on them. I ended up getting a Precision Matthews 1127. It weighs 500-600# plus about 200-300# for the rigid stand I built for it. It has precision roller bearings in the spindle, 1 1/2" spindle bore, bolt on chucks as opposed to the threaded on chucks that come loose in reverse, flame hardened bed, VFD, came with 2 chucks and a ton of accessories, a warranty, power feed in both x and y directions, quick change gear box, etc, etc. While its not the heavy 10 I dreamed of for years, it can hold .001 or less , runs very quiet, and even included shipping to my door. I'm not doing production work, although from what I've seen on youtube this machine can take some pretty good sized cuts. Best of all it worked right out of the box and I didn't have to spend several years finding parts and restoring it, although I'm sure there are a few upgrades I will do to it over the years. If you can find old iron thats in good shape , reasonable and isn't thousands of miles away, I say go for it and consider yourself very lucky. otherwise, I would consider PM. Matt over at PM offers great service, he even answers emails on weekends. He puts a lot of effort into making sure the Chinese build these machines to his specs and designs. I have no affiliation with this company, but my experiences after buying 2 machines from them have been very good.
