Brief Description:  Jackstand for wheel work - low cost and no welding

Thanks to all the people who have posted various designs for RV10 main wheel jacks.
I spent several hours experimenting around and going to Home Depot. If you follow these directions, you can do this in less than an hour plus any trips.

The key thing with this version is low cost and easy fabrication (for me that means no welding).

Parts required:
Harbor Freight 3 ton long hydraulic ram - flat bottom - $54.99
- make sure you get the flat bottom version versus the round bottom
- you may want to pick up a small bottle of hydraulic oil from HF to top off the fluid per instructions
3/4" x 2' x 2' plywood or reasonable facsimile
- you can pick this up at Home Depot precut
(8) 1/4" carriage bolts - 2" long
(2) hose clamps (about 6" needed to fit around ram)
- (1) 3/8" carriage bolt to replace tie down ring as a jack point
- (1) 10' length of electrical conduit (the smallest diam sold)

1) Cut 4 pieces of conduit and flatten ends in vise (don't fully flatten one end to get closer fit around circumference of ream)
2) Drill 4 holes in flat bottom of ram (turn it upside down on floor standing drill press)
3) Bolt ram to center of plywood, fit conduit, strap on with clamps, drill 4 holes in ply
The (8) carriage bolt heads now form feet for the ply
4) Carve out a depression on the top of the ram shaft to match the carriage bolt you'll screw into the wing tie down. I used a 1/2" bit to start and then widened with a Dremel.

Sturdy as a rock. All done.
