Lift Aid mount design parameters

[Sidecar Flip]

Okay guys (and gals), I need some help. You are going to have to get down on the floor (or carpet if you keep your Rocket in the house) and do a little measuring. I need a dimension. I need to ascertain the relative production tolerance between the lugs that extend down right behind the engine.

The distance between them. That's it. It don't have to be exact, within 1/8" woill be just fine.

Reason being is I'm working, as requested on a lift aid, but I want to make it one piece instead of 2 seperate feet. If it's one piece, it will add stability to the motorcycle on the jack (and I want to design it so that the aid can be bolted to the jack itself so you can move the bike around without having to resort to acrobatics or the cumbersome straps) and it will be less likely to get misplaced in your tool box.

I've been told that the Rivco centerstand (which also incorporates the lugs as a mounting point), has had fitment problems due to the lug spacing.

I need to ascertain the relative production tolerance before I execute the prototype.

I've posted a poll of spacing dimensions. The distance that's relative is the distance between the lugs measured on the INSIDE SURFACE.

Your help is appreciated.

Done. I would like to pre-order one also.

I'll have my 08 measurment for you later this am. I'm also in.

11 3/4. I voted.

11.889" flip with my vernier calibrated eyes. If you want I can get the tubular inside mic's out

We are good on the hole. Because it's metric it's slightly larger than 0.500" and I'll use 0.500" low carbon cold rolled rod. I just don't want to make it to fit my bike and find out after the fact that because of production tolerances, it won't fit half the bikes out there.

My overhead hoist in the shop is coming in handy. Beats laying on the floor looking up.

My concern with the one that was pictured in the thread is that with a small contact patch afforded by each foot and the fact that they are seperate and not attached to each other in any way, the possibility exists for a rocking situation plus seperate parts in the toolbox equals lost parts.

I'm going to make the base the width of the foot on our lift of choice, the Sears and Grabbuck or Hardon Fright red lift. I'm thinking I'll add a set of holes so if you want to bolt it to the lift you can.

I want a representative dimension figure so I can ascertain what that production tolerance is.

I'll stay tuned.

this works well for me

Travelguy....

Next time you have it 'up there' measure the distance. You don't have to bend over and you won't get your knees dorty.

Not everyone has a hi-lo available.

I hate to brag......but looks like my 11 7/8" is pretty much longer than everyone else.

Apparently I'm just average at 11&3/4"
