alternative Jack
in our hanger (two RV's) we use a HF motorcycle jack that has a flat platform top. One of the guys built a box to fit on top of it that extends it and has the appropriate contour to fit under the cockpit at the spar carry though. We use a furniture pad for additional padding.
It nicely raises the whole plane, and with slight adjustment, can lift just the nosewheel. Jim F RV-9A (220 Hrs.) |
The jacks are now listed on Harbor Freight for $54... :mad:

Just finished the Tie-Down assemblies on the two Spars. Had no idea they were that strong!

Went to visit local store, the jacks were labeled $39.99!! At the register, they were $54.99. :mad:
The manager honored the $39.99 price AND applied my 20% off coupon! :D Total price was just over $29 each!!! I'm gathering the other parts and will put my Frankenstein jack together soon. THANKS for the great idea! |
I built these a year + ago, have worked well for me.
I welded the jacks to steel plate, about 14" square, 3/8" thick. Bit heavier than the ones shown at the start of the thread, but totally no way they are going to tip over in normal use. ![]() |
Finished my jack project today. I am quite pleased. I used Greg's technique and drilled a hole in the jack shaft to accept the bolt assembly that screws into the tie down hole.
Anyone who wishes to borrow these jacks is more than welcome. I do charge Russians $20/weekend rental fee. :D |
Got mine done
The jacks are $54 now. I over did the bases a little, but very stable while jumping in and out of various RV's. The 3 inch exhaust clamp worked well for securing the 3/4" conduit to the jack body. My hanger always floods about a inch deep after a rain, so decided against the wood base.
