Can a Micro Seiki MA-505M2 from a Micro Seiki DD8 fit on Luxman PD-310 TF-MT tonearm base

Where there is a will, there’s a way. Especially for a machinist.

Yes you are probably right thanks.  I may have to find a machinist one or someone who can do it with some wood.  I was hoping someone had tried before and would suggest replacing the tonearm removable base with something else that would work with the TF MT..  Wishful thinking I  guess.

Just took a look at both turntables, the MS and the Luxman. Yes, I think you will need to have a special mount machined. Have a blank machined and a bar with two holes so you can scribe the spindle to pivot distance on the blank mount.
I have an aluminum bar made from a scrap piece of 1" x 1.25" with a spindle hole at one end and another hole to take a Starrett scribe at the other end. The holes are accurately machined so I can scribe the pivot to spindle distance very accurately. After scribing the arc on the blank, the machinist can proceed to finish your mount.

Thanks BillWojo.  Looks good.  That is helpful.  I use such a tool to be more precise than just using the existing arm hole in the TF-MT as a guide.
