Could a previous owner have used a threaded arbor in the live center not understanding the intended purpose ? It is possible the PO removed the ejection pins for some reason and lost them! It might be a one size fits all thing, at least a threaded ejection pin will make it work!
The thread is used to hold the hooting ejection pin in place so you don’t need a mallet to eject the tool!
The PM's are on backorder and I'm not inclined to wait. There are a number of innovations and upgrades on the PM vs the G0709. I like the flat V belt drive. I sold the G4003G like 8 years ago and dropped out of machining altogether. Bad hip (that was 18 months of hell). About the time I healed up from the hip replacement my day job went nuts, director to managing director which became all consuming. Finally I retired about 6 months ago and started getting back into machining.If you as are looking for a new lathe, you might also look at the PM-1440-2SM-V, larger spindle bore, heavier lathe with variable speed. Are you upgrading from your G4003G lathe?

The live centre was brand new, which is why it having a threaded end confused me. Again though, the arbour is fully part of the body of the centre.
, applying grout, etc.Was that 18 months from the start of your injury to recovery or, 18 months to recover from the surgery? Mishap after surgery?
I'm wondering if the rest of the system will accommodate the increased mass of the new arm? Do you think you might have to do some whittling on it to get the reciprocating mass down?
Seriously they sent you home same day? They kept me in the hospital for 3 days. Now the surgeon did say, (it was worse than we thought). I was like what does that mean?
My recovery was quick, I was off the walker after a couple of weeks. Just take it easy and follow the instructions about turning your foot inward. As gruesome and barbaric as this surgery is I was surprised how fast I healed up. The 18 months was from the start of the hip pain until they finally agreed to do the surgery.
Before I discuss your question: what is the model of the Warco horizontal bandsaw? While I could find room for the Grizzly 2x42 belt grinder, I could find room somewhere for a small vertical bandsaw if it's really as sturdy as that appears to be.
Can't answer your question about the load bearing capability of the new top as I don't have enough data (weight & footprint of the new mill, dimensions of the top, details of the frame supporting the top, where on the top will the mill be placed and how you are "laminating the two 1" think plywood layers – two continuous sheets tightly glued would be stronger than the multiple piece layout you have).
