LOL

Steve, you only had to ask and I would have renamed and editted the new
group accordingly and given you owner status.  I already had 29 members
signed up, and don't have any intention of 'moderating', hence why I had
volunteered 2 suckers, err, I mean members.

Hello Steve,
	I assume you know you need to post a message or two each month to 
satisfy the yahoo software. I moderate the hobbicast1 group for 
additional storage space. So far, 2 messages a month has kept yahoo 
satisfied.

Well,

I had the money now, so I ordered a complete set of precision rods and
linear bearings from here:

<http://stores.ebay.com/VXB-Bearings-Skateboard-and-Slotcar>, under Linear
Motion Bearings in the left-hand column.

I know I could have used ordinary rods and teflon bushings from the local
hardware store, but I intend to upgrade to full-CNC sometime in the future.
I chose 4 30" rods for the X and Y axis, and 2 13" rods for the Z axis; all
20mm diameter.

The pillow blocks were interesting, but I thought they were a tad short.  A
pair between 2 rods would be good enough for drilling, but I feared they
would introduce play for CNC work.  So I took the independant linear
bearings.  I can space them futher apart thus reducing play under stress (or
so I think).

I know I could have taken 4 blocks per pair of rods, but I wasn't ready to
spend that much yet so I compromised.   I can still order them later for CNC
work if the linear bearings are not up to the task, or too complicated to
get properly mounted.

Yeah yeah, I know, I'm a precision freak.  :D  Wait 'till you see the
finished machine, you won't say that any more.
