help designing shop stand for 911

[wayner]

I want to build a stand similar to the one Magnus shows in the pic below.

Most of it is pretty straight forward, but welcome any advice before I begin.
My main question is how tall should it so that it is high enough to do an engine drop.

I mainly want to be able to roll the car around at working level

Anyone?

Ask his highness

[wayner]

That was helpful. Thanks

Let me ask this another way.

" if you wanted a stand ( any stand) that will bring your car to a comfortable working level using a floor jack to get it there. How high should it be to also allow engine drops?"

Thanks in advance

Check this link from the 912 regisrty forum it might help

Body Cart/Lift versus Rotisserie for Rust Repair

My mid rise lift allows for dropping the engine easily.
I don't know the height as I'm not home but checking a few retailers for mid rise lift specs should give a good indication. 40 inches?

Be sure to consider the surface of your floor. If it's polished concrete, any casters rated high enough in weight will be fine. But if it was poured in sections with expansion gaps, or you have a somewhat rough surface, you will want to go with a larger diameter wheel than Magnus' cart. We have 6 inch wheels on carts inside the shop, and even have chassis carts with foam-filled "pneumatic" 8-inch tires so that we have move them across the gravel part of our parking lot. -- Matt

Edit: Wanted to add that I would opt for a 4-wheel setup rather than the tripod. Extra stability is good.

i would not do 3 wheels.

Wayne,

This is for typical SC engines seating of a cart/dolly 8" high.......36 to 38" from the floor to the rear valance. Without the rear valance you could dramatically reduce this height for clearance. A complete SC engine seating on the floor is about 28" high. HTH.

Thanks

Those are good responses and I appreciate it.

I now have a height measurement and also some good things to think about when selecting wheels.

Thanks everyone.

How would you get the car up on the dolly with jacks?
Pretty hard to do even without the engine in the car.

Not that hard, you use jack stands, roll the dolly under, then raise off the strands & remove them, lower onto the dolly..

Sorry that I don't have any pix of one, but they are very simple, 3 large pieces (6" I think) square tubing, welded to form a capital I, one cross member (for the front) a bit narrower, sitting on heavy duty casters. You measure the length based on the width of the jack-points.

+1 for not going with tripod design. I built this for our tub. Made mounting plates that bolt to the torsion bar spring plate retainer mounts and the front is mounted to the two large mounting bosses for the front suspension cross member. I likely have more detailed photos if interested.

[Jack Stands]

In the book, Excellence was Expected, Ludvigsen shows a picture of a four wheeled dolly that was used when they rolled the completed 914-6 chassis structure across the road (by hand) to the Porsche assembly line. It looks like it used the four small round points on the corners of the floor pan to hold the chassis. I imagine that a similar dolly could be made for the 911 as well.

We have a 356 dolly here that was built using specs from the Porsche factory chassis carts. I can take some photos tomorrow if anybody cares to check it out. -- Matt

[wayner]

This is great stuff! Thanks everyone

I just purchased four jack stands that lift the car 26 inches and one can place one or two 2x10 under each stand for an additional 3 inches. The great thing is that each stand has it's own bottle jack so they are serve as a jack stand and a jack. They were cheap..............$80 a for set of two.

You starting another project or do you just want height and mobility for your existing car??

My buddy has these and I think they are the cats meow for pushing a full car around the shop plus for getting underneath for simple jobs. Takes literally minutes to do and universal for any car. Less of course if you are doing any suspension work, then I am a huge fan of a mid- rise lift.




Loved your build by the way!
