Default Replace Jack Stands with wood platforms

I will be doing a lot of rear suspension work on my '77 and I don't trust the Jack Stands for various reasons. I have seen several instances where guys have fabricated stackable wood sections that makes working under the car much safer and less stressful. Does anyone have photos and or dimensions on how to DIY these items? Thanks

Works GREAT!!! 2 x 4s- I used 3 1/2" deck screws to build and carriage bolts to connect two stands together- 18" height -Super sturdy.

I made some years ago using this design:



The main supports are 2x lumber sandwiched between 3/4" plywood. I used 2x6s 15" long to make the base set. Width is 12". I also made a shorter set using 2x4s that will stack on top of the base set (lower right image). You can fill in the spaces between the 2xs if you want more support but it makes them much heavier. I've used this set on both my Vette and my Suburban without issue for many years. Add gate handles to them to make moving them around easier. If I was building them again today, I'd figure out some way to pin them together when stacking. There is no issue once the weight of the vehicle has settled on them but they can move independently a little when loading and unloading.

I have a QuickJack but I still like using the wheel cribs when possible to give more working room. But, it is a little more challenging to set up on the wheel cribs using the QuickJack since it moves laterally as well as vertically. I have to keep re-adjusting the wheel cribs as I lower the car onto them. Sometimes I think it would be helpful to have wheels on the cribs but haven't gone down that road yet. I do have a set of wheel dollies but they don't put the car up in the air enough to do anything underneath.

Good luck,

DC

Just curious, what do you use to get the car that high up so you can use the wheel cribs?

I've got a HF Daytona Jack - almost 2ft of lift- and I'll put it a couple of 2 x 10s underneath it.

Cool as hell. I thought it was something like Kinsler fuel injection at first, but there were six throttle bodies per side...

OP, sorry for hijacking your thread.

I built them out of 4 x 4's, plywood between sections, PL400 construction adhesive, and timber lock screws. Very solid.

You better hope you never have a "shop fire". It would take two hours to get the car out the door.

Pro tip: Don't buy your 2x4s at Harbor Freight.

Buy a Kwik-Lift off of Craigslist. I used mine to replace every bushing in my 80, brakes on both cars, and a bunch of other stuff. I later sold it for about what I paid for it.

The frame on the cribs- holds the frame better than any jackstand.

Have a lift in my upper garage but not the basement...
