Since I posted this thread on jacking up the car

http://www.bimmerfest.com/forums/showthread.php?t=450867&highlight=jacking+up+the+car

(and having been criticized by some for not being safe) I've been thinking how to improve the safety of putting the car on jack stands using factory jack pads and jack stands with common saddle configuration. I first cut small maple wooden blocks to fill the pad with and increase the contact surface of the pad and jack stand.

But I still wanted an adaptor. I found a couple of products online but they all had their drawbacks, were too expensive or not longer available.

So, thought I'd share this with you.

I recalled having read about people using hockey pucks to jack up the car and decided to make an E46 hockey puck jack stand adapter. The cost is $1.50 per puck and 30 minutes of cutting and filing :D I made it, tested it and should say that I'm 100% happy with the result. The car is not going anywhere using these adapters. The idea is to use the jack stands with the saddle that is as flat as possible. They are available in many weight categories - 2 1/4, 3 and 6 tons.

The adapter looks rough because I used only a hack saw, a double cut file and a c-clamp to make it. But it does the job.

Fast Bob seems to be the only one excited about my puck adapter :rofl:

I'm heading down to the basement right now to make 2 more of those (I already have 2)

Happy Labor Day everybody! :)

This is very awesome! Clearly you don't have 4 kids and a wife with all that time on your hands!

I think I must needs make some of these. I wonder where I can get a hockey puck in my neck of the woods. We don't play hockey down here......

BUT ROLL TIDE!!!!!!!!!!!

Dude...that's awesome!


Gives me an idea for my racing jack, since the jack point on the front in the center/middle of the car is not that strong.

That is interesting. On my car which has the older triangular brace, the front jack point is very strong and I use it all the time. I wonder if you could just bolt on the older triangle support?

Not 4, one is more than enough for us :rofl: But this car is my only hobby, spending most of my free time with my family I need a break once in a while for a diy project :)

Looking for a hockey puck I went to Walmart and Target - nothing, Dick's sporting goods - nothing. I came across the place called "Total Hockey" and it was my luck that on that day they had sold 150 pucks to a school team and were sold out. There is a skating ring 5 minutes away from my house and I stopped by to ask, to my surprise thay had a little store selling pucks among other ice hockey stuff and even a vending machine with pucks among snacks. So it was not that easy to find. They are $1.50 - $1.75 online (before shipping).

Great idea, will have to try this. Did my rear brakes today, have the fronts left to do, the lack of central jack points ticking me off again, you like the frame rails?

Yes, the I jack the front under the front part of the frame rail on one side , put a jack stand and move to the same location of the frame rail on the other side to put it on the stand. It works really well for me. Rear is simple - U-brace near the differential.

The aluminum plate that replaced the triangular brace seems to provide a good bit of protection against road debris. It probably also improves undercar aerodynamics.

The jack point isn't the aluminum plate itself; it's the front subframe directly above the embossed oval. The oval crushes easily, even when you use a jack with a rubber-cushioned saddle. Mine looks awful. Starless' jackstand adapter has me thinking about making an adapter for the oval.

Nice job, Starless! :)

Guys, What a jack point are you using, on the order to to put car on the stand?

I have use middle of the car and metal is deformed a little, then move to close the front of the car right near the jack point, but metal is deformed too.

Good idea, except that it`s likely the effect of the PSI load applied against the aluminum plate that`s distorting it....the hockey puck won`t change that....

Fantastic!

I'd run and build one right away also, but I'm in Denmark right now and I don't think I've ever seen them for sale here.



I will definitely do it when I am in CT though!

What I did is, I took a piece of wood (2 by 3 or something like that) that's slightly larger than the lift part of the jack. I put it dead center on the jack's handle and lifted the car. From the weight, the "teeth" of the jack left marks in the wood that I now use to position it on the jack (hydraulic jack by the way).
It won't work for jack stands obviously, but it works great when lifting by the rear suspension bracket.

Alex, your puck adaptors are a great idea. I made a set for myself before I did a lot of under-car work this weekend, and they worked great. I'm thinking of making a couple of jigs for my router table and cranking out a bunch to sell to our fellow Festers who live south of hockey country.

Well, they need to be customized to the specific set of jack stands in order everything to be near perfect. That's the problem with mass production, also you do not want to be responsible for anybody using them other than you and having an accident (god forbid) And sometimes it's hard to find 3 or 4 ton stands with FLAT saddles. My 2 1/4 stands work perfectly, however I want to use at least 3 ton for any serious work under the car. I found these:



Omega HW93503, 3 Ton Jack Stands

The saddle looks pretty flat on those, but they are around $70 per pair. But that's your safety so I'd prefer "professional" grade of equipment and that always costs money

But if can make them "universal" adaptors made out of metal using your puck as a matrix, then selling could be a good idea :thumbup:
