Thanks for that, I now know what to look for in my next lathe!
Your welcome
Regarding CNC, I would have thought that would be more fussy with set up than normal where the operator can compensate.
Oh, they are but they use different technology like crossed roller guides instead of doves and ways thus no info on the topic.
Keep up the ferreting.
Will do.

Your descriptions would certainly fit with my experience..... Could really take some metal off with those machines, miss them now that......
It's about leverage and controling that leverage, right?

Useful comments re saddle adjustment priorities. Thanks. Re the bed width, I can read that 2 ways. It either puts the Sieg 7x just on the
junk side of "tool room" and close enough to be worth investing some effort into. Or it puts the Sieg 7x just a whisker short of "heavy duty". Well, it ain't the latter!
Seig center height 3.5", bed width 3.25", closer to the junk room (hobby class:-) It's still workable, it just isn't going to take materail the same way a more robust designs would. My contention all along has been " work inside the design". Have to know what you have to do that, right?

The Myford ML7 is 3.5"centre height, not including the gap, which is~5". The bed is 4.5 inches across, but the spindle is not centred to this, it is 2.5" back from the front shear. Would this be to give akind of 'effective' ratio to make it more capable when using the fullcapacity of the face plate or 4 jaw, both of which sit in the gap?
Absolutely. Add's about a half inch to the swing capacity. Consider what that means though to work from behind the work piece and how it affects the saddle load.
Someone asked me when I first started the Project Lathe if I was planning on adding a "real" back gear. Seemed useful but pain staking at the time but I may just have to whittle out a new head stock anyway. Glad you posted as I was considering lowering the center height a quarter then using Chris's shaved tool slide to regain the difference. This whould also reduce the swing over the saddle dimension a like amount though. Now moving the center back just may have more merrit and make it worth the trouble. If I go that far a back gear becomes more plausible doesn't it?
