Dual 1249 Tonearm replacement


ok, so I have a design for a tonearm that I want to apply to my old Dual 1249 (I have a Dual 1219 that I have a custom plinth, Denon DL-103, used with a Linn LK1 preamp).
I want to experiment with at least a 10" arm, maybe a 12" one.
I can make a precise plinth that incorporates the correct mounting position, but would like to know how much of a pain is it, to take the stock arm off and have the motor still turn? I know I'll lose any automatic functionality.
Is it also a good idea to turn the table 90 degrees clockwise to aid in tonearm positioning? Looks like I'd have to if I used a 10" tonearm because of the cutouts on the existing 1249.
Hope this makes sense :)

Ditch the 1249 and mod the 1219! 
I have a 1229 and replaced the original Dual arm with a Grace 747. 

I have also had a SME 3009 on the table but now use that on my Garraed 301.

I removed all the automatic functions, and used a set of springs to tension the original on off switch. I also use a tone arm lift  for end of record play. 

The 1219 can be made into a killer turntable. I have a EMT 927, a Garrard 301 and the 1229. The 1229 is my favorite and gets daily play.
