Default 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.

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

Angry

Went to visit local store, the jacks were labeled $39.99!! At the register, they were $54.99.

The manager honored the $39.99 price AND applied my 20% off coupon!

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.

Here's how I capture the wing bolt without worry of it coming off the jack. I JBwelded the wing nut on (backwards) so it is easy to spin the bolt in and out of the wing tiedown. The oversized hole allows for the slight angle of the bolt in the hole. I also notched the top of the legs to keep the band clamp in place.

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.

Default 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.
