Nice job! I've got the J&S Air jack, but I've NEVER felt the need to tie it down like you do. My Electra Glide is just rock solid on that damn jack. Have you ever had a problem???

How many pumps does it take to fully lift the bike 10-12?

I suppose if you have a disability or use the jack many times daily air would be a good option to have.

To each their own, I'm sure there's things I've done that others don't understand the reason why.

I still use the J&S, but felt silly pumping it with my foot with a compressor right there...

So I wanted to see about converting the J&S to air/hydraulic....

I called J&S, since they offer an air/hydraulic version of their jack. They said I couldn't just convert my jack because I would need to change the base plate and other parts...... hmmm

I searched & found the Strongway (#46209) 5-ton air/hydraulic bottle jack. It has about the same dimensions as the manual J&S pump.... close enough to work with.

I was able to mount it to the jack, add the handle, and now I can just wheel it around, hook a hose, and pump it up!

Not being a fabricator, I was able to make it work, but didn't figure a way to align the manual feature so it was accessible....

I posted my conversion and since then a couple of clever people have found a way to mount the bottle so the manual feature is easily accessible.

So we basically now have the air/hydraulic version of the J&S jack for about $70....

So..... "need to", absolutely not..... but "Want to", in my case, yes......

I'm glad the OP figured out how to do whatever they wanted to do.
Let's face it I'm sure they don't give a $hit what I really think.

Oh, and BTW, it takes a LOT more than 12 pumps to get the bike all the way up.... again, Just Sayin'....

To me, it's a waste of money to have an air actuated bike jack.
