Fitting P201 to a generic engine stand
 

So the rotating mount on the P201 measures 57.5mm and the ID on the generic engine stand collar is 60mm.

For the most stable setup, I'd like to 'sleeve' the engine stand collar for the smaller shaft.

What has anyone used?

I've heard (thanks, Zeke!) that a strut body is an excellent sleeve -- but a strut that can be cut up is a rare bird...

Any other solutions before I go shopping for a short piece of thinwall steel pipe?

I'm wondering if another type of material would be suitable/improve? Brass, PVC, monkey hide, etc.
It must stand up to the weight, but the rpm's are pretty low!

LOL!

For a wall thickness of 1mm, I think we can rule out the PVC, but how're you fixed for monkey hide?

Come to think of it, the cheapest commodity in this town is spec movie scripts... I could probably use a couple scenes' worth of dialog to fill the gap...

Sounds like a lot of work for very little return. While there may be a bit of a gap (<3mm) I can't say as I ever noticed any stability problems.

I mounted my P201 to an inexpensive Harbor Freight engine stand, and it worked fine. I rotated the engine many times on the stand without problems.

Funny. That's the exact same Chinese made stand, Danskman, $55 worth, in my neck of the woods.

I understand it may not create issues, but I'm not good at ignoring the basic concept that I'm using a cheap stand to hold up a $300 engine mount and $2500 engine... I'm looking to create a better distribution of stress on the stand yoke.

Knock yourself out, but these things are made to be used with cast-iron V8 blocks that weigh much more than a 911 engine.

cut up a milk carton (the plastic one gallon kind) and wrap that around the sleve then insert...

Cool! I like that!

Thanks.

"Knock yourself out, but these things are made to be used with cast-iron V8 blocks that weigh much more than a 911 engine."

You'd be surprized. My fully dressed 930 engine in stock California smog trim wieghed a whopping 530 pounds! I was very afraid to move it around on the stand.

I rebuilt a Ford Cleveland 351 V8, rotating it MANY times, on a POS Northern Hydraulic engine stand without any problems. That engine weighed more than my mother-in-law!http://www.pelicanparts.com/support/.../gaapslaap.gif

I wouldn't worry about the 911 engine.

I've got my 3.6 on exactly the proposed combination, currently. Actually, my stand is more than 10 years old. I never questioned that it wouldn't hold. It has been fine for a week. It didn't occur to me that I'm walking a tight rope. However, i don't think that I am. This feels stable.

I'll take a close look at the welds for cracks.

Bill,

I have one that I bought off of Pelican. A gent in San Diego made the "ring" and then mounted it to his HF engine stand. Worked very well with my 3.6.

I have had a Jag engine on a HF engine stand but you could tell that it was straining. It weights a lot more than a 911 engine and is just plain a PITA to move around. If I were doing much work on a expensive 911 engine might do some re-enforcement welding on the stand.

Watch your local HF flyers, I bought the exact same unit about a month ago for $34. Coupled with the MBD ring, it holds 'em well.

I use the same unit as Danaskman....with a few mods.
I removed the center leg & welded up one on either side so's I could get a jack directly under there. Tain't pretty, but works slick.

Yeah, I hear ya. I know it's "within tolerance" but I'm thinking about fabbing a triangular brace to the groove of the fan pulley just to make me sleep better at night. Magnesium doesn't really have that much memory or rigidity...

Believe it or not, it was on eBay for $0.99 with $39.99 shipping! I just grabbed one locally because I'm impulsive that way, and I wanted somebody to go yell at if it were incomplete or defective.

The HF headquarters is a reasonable drive from here and they have a retail store in their (two square block) building. It's dangerous to go there... for tool shopahoilics like me.

attaching tens of hot air balloons to the motor could help reduce load..?

How about left over shims from some elephant racing poly bronze :-)) I have a bunch left over.

That's exactly what I used to have. It had two legs and the base was shaped like a "U". I gave it away years ago when we moved, and I couldn't find another one like it this go around, so I settled for the HF single leg, inverted "T" shape. Definitely not as good as the "U" shape for reason you mentioned.
