Fitting adjustable feet to a chassis dynamometer

[poxxxy]

Hi guys,

So I have a 2wd chassis dyno that I need to get installed, I bought some m12 adjustable levelling feet but I am wondering how I can secure a nut at the top (in particular without welding it) so that I can wind the adjusters up if necessary in situ without the nut that sits on top moving. Only way I can really think of is welding the nut to the chassis which is less than ideal although I will have to weld some plate to the chassis in order to attach ramps. Not sure if a couple of nuts locked against each other will end up working, have a feeling it wouldn't?

I guess I'll have to borrow a forklift, get it up high in the air and weld the nuts on the back but just wondering if there is a route I can go that will avoid that scenario . Do have to drill a couple of holes for extra feet ideally also to help spread the load.

Could you tap some 10 mm plate that could be anchored to the frame without welding?

I think M12 is a bit weedy to support your dyno, you're hoping to lift something heavy screwing through a single M12 nut only 10mm thick! I would suggest M16 or M20 would be more appropriate.

If its going to be permanently located once you have it leveled make some L brackets from steel, bolt one leg into the floor & weld the other leg onto the frame of the dyno.
