Vintage DD turntables. Are we living dangerously?

You can’t do anything to mount EPA-100 mk 2 on Luxman, people have no idea what they are talking about! It’s impossible, no matter how many metal or wood boards you can do, the mounting hole of EPA-100 mk2 is huge! This tonearm is not compatible with luxman pd-444.

I have two PD-444 turntables and all LUX arm bases.

3 arms arround turntable is the ugliest thing I ever seen, leave it for Micro Seiki owners. Luxman designed for 2 tonrarms and it’s state-of-the-art turntable. If you need more buy another luxman pd444 for another 2 tonearms.

Welcome to PD-444 club @luisma31 
I too think 3 tonearms on any table is ugly. Sometimes more isn't better. Luxman designed the perfect looking table with the ability to run two arms. Perfection!

@Chakster That's nonsense.  What diameter hole is appropriate for an EPA 100 MK-2? If Micro Seiki never make one, the OP's machinist could easily fabricate or over-bore one that will pivot off an outboard pillar.

60mm hole.  The mounting plate on the back of the armboard will be 69mm or 79mm depending which version. 

Luxman armbase size is about 60mm on one side, so you can’t make a 60mm hole in 60mm armbase, also there is a lock mechanism inside the armbase. This base is not designed for tonearms with huge mounting hole (bigger than the base itself). Ever seen a PD-444 armbase or EPA-100 mk2 tonearm together? @dgarretson
