I'm in agreement with you. Just wanted to point out that even if the tension is too great, it may be easy enough to solve that problem with a second bracket instead of going to such great lengths with the original design.

Slippery said:Not trying to be a smartass, but I think you guys are overthinking this. You are looking at failure points and while you have no idea what the bolts can take, I bet its more than you think.
The engineer in me does this. I also bet that it would not fail immediately. It would take numerous loading cycles. I use to build race cars. I was always looking for the failure point in them.
Slippery said:Why do you want to weld the machined plate to that other piece? Can’t you design it so that the machine plate attaches to the manifold directly?
If you need that lower piece reversed engineered I have a CMM we can use to do that.
my reasoning for the 2 septate pieces is that i dont know how far forward/backward ill need to move the blower to get the pulley to line up with the current accessories. So i can have the 2 plates sat on top of each other, slide the blower forward/backward until it's in the right spot, mark it, then have them welded together. Also, i emailed you the file to look at.
Ideally i'd like it to be one piece but im not confident in my measuing abilities to make that happen.
also for people wondering about snout length, it is pretty short on the m122 blowers, im not too concerned about the bolts abilities to be able to hold everything together.
Another note, i just bought a m122 from a guy in texas for $375 shipped, i feel like that's pretty cheap for a blower this size.

I get it. I am a Mechanical Engineer myself, but I am more the Colin Chapman type 
I wouldn't be worried about the strength of the adapter plate or fasteners. Supercharger belt tension is something on the order of 70-100lbf, so double that since the belt goes up then back down. The rated clamp load of a properly torqued m6 grade 8 bolt is nearly 2000lb. I'd actually be more worried about the boost pressure pulling up on the blower than the belt pulling down (more worried, but not worried). If the bottom of the blower is 5x8 inches, with 10 psi, that's 400 pounds.
With that short at snout it really should not be an issue. I was worried it was like some of he long ones you see on M90's The lever action and the forces on those units is quite large
On another note I got the file and I can not open it in either autocad 2017 or revit. Is there a way to get it in autocad?

That is beyond me, i dont think i've ever messed with any kind of autocad systems. I am a simple man haha
Exporting as STEP file should be more compatible when going between CAD packages.
I have the full version of Autocad 2017 as well as Revit and neither will open it and or import it. It looks like it is only compatible with Autodesk Autocad Mechanical and Id ont have that. At least Id ont think I do unless it came with one of the suites I have from them. I will root around later.
Ok after some fooling around I can look at in the Autodesk viewer and take all the relevant measurements off the piece so I can now regenerate the piece in AutoCAD. How soon do you need this? I was hoping the viewer would let me do a save as but I can not get that to work.
With viewer it has built in measuring so recreating this is now simple
I opened it. Its not a type of file you’d be able to open in Autocad.
Edizzle89:
I have the material in 3/4” thickness. Ideally I’d like to skim top/bottom surfaces, so that another .05”. Does ~.7” work for you?
If that works, you pay for shipping and can give me around 2 weeks we are good to go.
edizzle89,
did you draw this up or picked up from someone else? I have a couple of questions:
- the tapered hole you mentioned is not there? There big round hole has a step, is that what you want or you want me to blend both surfaces and taper it?
- one of the mounting holes has a counterbore, is that correct?
- also all the holes on the perimeter, those are not threaded. Is that correct?
Can anyone tell me if the link above worked for them? It should take you to the on line viewer for Autodesk and let you see and manipulate the piece.
In order for me to manipulate that file I would need it to be converted to a AutoCAD or some other 3d file format that Autocad can read. Then it would be easy. Makes me want to get my hands on the AutoDESK AUTOCAD Mechanical
In reply to dean1484 :
Link works for me. I can see the part.
Figured it out you have to manually tell it to import and select the step option form the list of file types.

That is cool!!! Thanks!!!
And now I can re design it.
Screen shot of it in my AutoCAD
This has been cool I learned something

the .7" will work. for the large round hole you can probably do whatever's easiest. It could even be cut straight to the larger diameter if needed. I think the counterbore in the mounting hole if for an alignment dowel which i probably wont need. As for the holes on the perimeter, I would like them threaded if possible for a 5/16" bolt.
I will be more then glad to cover shipping any anything else or this, you are truely awesome for doing this! i can't explain how much i appriciate the help with this.
Sorry to bump an old thread but just wanted to give Slippery a shout out for getting the plate made up for me. The guy does awesome work. The GRM community has yet to let me down!
That is exactly what I had in my mind when I saw the CAD drawing. Nice!!
Nice! Now we're counting on you to do something awesome with it!
That is really cool. I may be bothering you all for some parts for an m62.
You'll need to log in to post.
