Homemade car stand. Thoughts?

Hi,

I'm making 4 stands to put my car on for working under it. I'll jack it up and put them under the tyres.

It's 20 in by 12 in and 5 in high.

Any thoughts on the safety of it?

Thanks!

Ps this is just a mockup, I will screw it together.

Is 5" height to the bottom of the wheel a bit low. Sounds low

here is my attempt. I went a bit lazy, as didnt want to jack up all four corners.

she drove up on these really easily - I did chock the rear wheels, although you cant see it here.

These give more height for small money.

Its very hard to do any work on a car, lying under neath it. What work are you intending to do?

The design looks pretty strong anyway and given its size and proportion it would be perfectly steady

Or cheaper again and more height

Given that you are going to use 4x2 cls timber and screws, thae axle stands are a cheaper option
and will last longer.
Your lift blocks will do the job required.

Hi thanks for the feedback. And good to hear it looks safe.

I know 5 inches is not much, but I had two wheels up on the kerb which is 4.5 and I was able to get under. I'm very slim I can have the option of putting another layer on .

I'll be changing the engine oil, filter is underneath, and the gearbox and diff oil. And other stuff as it comes up.

Kadman, thanks for the links. I know this sounds silly, but those ramps (not just the ones you linked, any I mean) always look unstable to me. I do have axel stands like the ones you linked (ratchet ones) but again I think I'd me more comfortable with the blocks.

If I need to remove wheels I'l use the stands and put the blocks under the sill as a fail safe.

How high was that lift? You look to have used 6 or 8 by 2 there?

Jag looking good!

I like the idea of these but I always wonder would these not slide when you try to drive onto them.

I cannot see how they would slide away from you, the rotation of the wheel
when you drive towards them would be pulling the ramps towards the car surely??

I have to say I feel the same, I think the likelihood of a dodgy weld on those, or me damaging them driving onto them is way higher than the car splitting the wood or crushing it in any way.

Thanks - its about 7 inches all in. I also have jack stands which I used to proper her up while the wheels were off, but if I can I rather keep them on and drive up onto these.

Everytime I see them i cringe, I mean I'm sure they've been safety tested properly but the gauge and size of the angle bar they use just doesn't sit well with me. I'd never buy them.

I don't think so, the wood will be in compression.

I did a test with just one 4x2 and no central support, No cracks or anything.

Wood is in compression at 90 degrees to the fibre direction. In this case its weaker than if compression
happens on the end grain of the timber, as in a timberframe scenarioo.

If the timber has support directly under the tyre, and directly under each layer. Then support
issues wont occur. Support problems occur when you have timber in this scenario, either of a
thickness issue, or support issue.

This wont happen, if its basically a layer cake construction, and no unsupported layers.
