Anyone own a GH1440W lathe from Modern Tools or a PM1440HD from Precision Matthews?

I've noticed that the headstock on this lathe is taller from the centerline of the chuck to the top of the lid and adding the tool tray had made it taller still. The consequence of that is the chuck keys are too short so the T handles interfere with the tray. I have quite a bit of 1" cold rolled so I made up 2 new handles. Of course the 3 jaw and 4 jaw chucks take different sizes:confused:. I was able to improve the fit of the square end of the keys over the originals also.

Nice.
I have the same issue on one of my keys. Its on the to-do list. One feature I have come to like is the tommy bar has a slide fit so you can slide it to one side. Not so much for gronking but gives you a bit of leverage and its off to one side instead of interfering with the headstock if the nuts aren't quite upright. The commercial tommy bar has these rubber end caps to retain it. You could either use your new ball maker for the classic look. Or one simple trick I did on a similar handle is to machine a groove depression out near the end & install an O-ring so it stands slightly proud. Its very resilient & has a nice dampening effect if the bar slides down.

Certainly the way to go. One of the Youtubers made a special 'front Key' for doing 4 jaw work - it was around 10" reach... On my old lathe, the 3&4 jaw chucks had different sized keys. My new one uses the same key - go figure!

As I mentioned previously, I'm not too happy with the piston style quick change tool post that came with the machine. I ordered a wedge style from All Industrial Tool on eBay. I chose this one as it looks very much like the one I had on my old lathe and the shipping was reasonable. It arrived yesterday and it looks pretty good. It uses Imperial threads (5/8" X 18 on the post) like my old one did and the machining is pretty nice. I had to mill the base to fit my compound and at the same time I disassembled the compound and cleaned and inspected it then drilled and tapped two m5 holes for set screws to hold the base from sliding in the compound.

The machine work on the compound is very nice. The more I use this new machine the more impressed I am with it. 20190327_191922.jpg 20190327_161014.jpg 20190327_161025.jpg 20190327_155608.jpg 20190327_160310.jpg 20190327_161102.jpg 20190322_114500.jpg 20190322_114452.jpg 20190322_113825.jpg

Good job.
Are there T-nuts to secure the compound after swivelling to new position kind of like your Cantek lathe or something better?
