  Thanks for the info, Paul,
  
  I found them listed here:
  http://www.magnetechcorp.com/
  
  It seems the R0712-12 holds 9 lbs, while the R1007-12 holds 26 lbs--no
  wonder you picked the latter!  And each draws just 0.12 A and costs
  less than $30.  Not bad.

searching for the bill for my  electromagnets; 'couldn't find it. The two
magnets I purchased had part numbers  of R0712-12 and R1007-12. I think the
first two digits defines the holding force  in pounds, and the final two
digits gives the voltage. The 1007 is 3/4"L and 1"  dia., and the 0712 is 1"L
and 3/4" dia. I used the 1007-12. I mounted it  with an angle bracket in the
back corner of the  nose-gear cutout opposite  the hinge-line; they are tapped
10-32 in the top center of the round  device. I set the bracket sligh;y higher
than the final position, then shimmed  the coil down to the proper place with
washers. Opposite it on the gear  door I mounted a round pole piece. I
actuated it from the gear switch in the UP  position. It really "sucks" the
door closed! I found a web site, AEC Magnetics,  www.aecmagnetics.com, that
has similar  units for 12V and 24V.
