Thanks for that.

I'm not afraid of a little soldering.  My current plan to ready my house for 
the machine is as follows.  First, I have a wood floor that's suspended above 
the ground by various things in the crawlspace.  I'll have to get down there 
and add some extra bracing where the machine will be.  I'll lay a solid slab of 
strong wood on top of the floor to spread the weight out.  Second, I'll have an 
electrician install the necessary power circuit.  My ballpark figures tell me 
that I need capacity for 8-10kW.

My house is small, but big enough for the 11/70.  In a year or so I will be 
building a new house, complete with its own machine room.

I figured it might me something like that.

Ah, a washing machine.  I don't have room for it now (well, not where the 
machine will be), but I will in the new house.  I've found a person that might 
sell me a RA81 to use until then.

Hm.  I'd better start looking now.

Thanks for your response.  You have been extremely helpful.
