Adam is probably solid works. I'm not sure about Tim. When I attempt this stuff, I use rhino3d, haha.

Man what I'd give to be able to design shit like this. I hope that you love your job Tim. I'm jelous. What's the issue on the rear of Volvo's that there isn't a proper upside down thing residing in there?

Some cars use things called "shocks" and Toilettas, and old Fords, Xratties and VW and Volvos use these old things:


That's one of the 50mm (same internals as your Soooper Bitchin JVAB struts) magnesium bodied shocks I bought used from Stig Blomqvist in Sweden.

The steel ones work the same just weight a pound more.

So Adam, I've always been wanting to try that sliding pinch bushing trick since I first saw it on a Swift FF about 10 years ago. How critical was the fit on the bushing to keep things tight and not knocking about smushing the hole oval?

What are you seeing? What's the point?

On Adam's model there is a section of box tubing on top of the turret. It has two pieces of 0.75" OD x 0.50" ID tubing running across it where the bolt mounts. One side is welded solid on the outside and the other slides thru a (my question: precision bore or just drilled hole).

It's usually done that way on lightweight formula cars to protect the casting on a transaxle where a rod end bearing mounts. The sliding section of tubing keeps hack mechanics from over tightening the bolt and breaking the ears off. As a bonus it's cheaper to make because you don't have to hold a tight tolerance on the slot.

Maybe it's that lack of imagination/creativity I was saying I suffer from, but
"what da fawk?" Sounds like an excellent opportunity for having a bunch of slop develop over time and the vital red spacer to disappear in a hurried (or ya think of it, more lkely a lazy in garage ) shock swap.

Still don't understand what is the point in this application.

Never saw any particular shortcomings with the Xratty top mount.
Hold the shock up, slide a bolt thru.
Seems easy 'nuf.

Calm John, breath deep, now exhale... I wasn't planning on using it. I was just curious how it worked for him.

I know you wuzzzn't gonna, I am just curious what proble this supposed solves cause I dun understand nuthing, I knopw Adam is an astute fellow, and I learn by unnerstandk howz other guys think they're solving problems.

Or......... is like when the US Army guy back at the old Checkpoint Charlie an der grenze im Berlin shouts to Ivan just accross the line and says "Ivan, run for it! Come on over! We'll cover you!"
And Ivan shouts back "Why I come over there? We have best system in Sovjet, better than Consumer Capitalist Wage slave live you live! HA!"

The US Army boy is dumfounded and shouts back "Better sysytem?? Are you crazy? How is Soviet system better, We have everthing here!??"

Ivan shouts dripping with contempt "Sovjet system much better! We solve problems you don't even have in the West!!"

I don't know why Adam used that design in his application. Maybe he just wanted to play with it and see how it worked...I do that sort of thing all the time. Not everything Ford did back in the day is the end all and be all of designing race cars :-) It is a particularly elegant solution for preventing damage to cast mounting ears. I have a better drawing of what we're talking about below.

The suitability or necessity of the sliding bushing on a ductile mild steel mount is not what I'm asking about. I just want to know what kind of tolerance he has on the bushing fit and while we're at it what's the wall thickness of the box tube?

SW2008,
Looking for a job near / in Redmond after DooWops.

It is working fine, way better than for the first 3 years of prepping/rallying where the shock eyes were free to bounce forward and aft inside that housing as they pleased, creating some nice clanks at full droop.
the reason i'm not going for Johns pressed in superfly reducers is,
shocks ship with 1/2" eyes, from bilstien. the rest of the car's 4-link is also 1\2-20.
i never managed to ovalize the 1/2 drill hole, so i'm even less concerned about it now with a much larger bearing surface.

i actually used a drill bit (3/4"winking smiley, and doubled it with some left over tube, tweaked in the lathe. the clearance isn't critical, and as a bonus, was tightened when the blue extra guide was welded to the main piece. you would have to try really hard to loose it. (blast it out of the car)
I have occasional access to a lathe, not enough to do up 20+ reducers, but enough to part a couple non critical lengths of tube.

i have run my shocks upside down, and the bearing height is much closer than you show, that's why there is an enlarged hole and gap cut out of the square channel.
