New Idea!

[bmws50b30]

I'm down. just let me know when. thanks. does this come with the tranny bushings? i'm guessing it doesn't, if so what bushing is the best to use?

[Addissimo]

It doesn't come with tranny bushings-

If we can get 10 or more people to order poly bushings from ireland, we get 15% off of $80 for a set, so about $70.

Keep in mind this will require drilling and tapping a hole for which ever mounts you decide to use.

If we get a group buy going on the mounts, I'm willing to do the labor on this for a small fee (probably like $5 or something)

I'm in if we can get it in the ~$60 range. I won't be installing my motor untill mid January, so that's no problem for me.

poly bushings would be nice but my priority right now is to have the correct bracket. drilling the holes bigger should be easy. the brackets have the mounting holes pre-drilled, correct? when would you start production of these?

[Kilomph]

Addissimo, you're the man. I'm in for the IE poly as well.

[02stu]

Wow, thats all I can say. Addissimo do you have a paypal account? If so I'll send you the money now, and when ever you get the parts is fine, no rush. Just send me a total and if its ends up being more I'll send you more. If they are being sent to you I'll send you a prepaid package. Thanks again Addissimo!

What material and thickness is the brace going to be made of? 1/4" billet AL?

Regardless, I'm interested in a brace

[Addissimo]

It'll look like this:



its 1.45" thick.

This is basically the only design I can really come up with that makes sence. We could make one that is extruded like the stock brace, but I'd have no clue how to go about designing that. I think this will give us the most strength and lightest weight.

[02stu]

That design looks good to me, but if you want I can draw up any changes you had in mind. I've never used there program but I could draw up a brace on a more widley used program like solidworks that I know they would accept. PM me what you had in mind, it wouldn't take me long. I'm not sure how it would effect the cost but if we filleted the edges we could get rid of the stress concentrations and have a much stronger part with less material.

[BimmerToad]

Filleting the edges is a must, and having a much thinner bracket would be nice. Most applications that use aluminum use it with a much thinner wall. From what I remember from an engineering materials class I took, the materials resistance to fracture increases when you decrease the thickness. (I'll re-read that stuff after finals week)

Did you modify the right mount geometry too, or just the left side?

Good initial design. Hopefully a final product will come out of it :D

[e30sd]

i'll buy 2, one for me, and one to throw at todd.

100 bucks is fair imo, anything cheaper is sweet.

[rede30]

If it comes down to needed more people to buy i might buy two, hell i might buy two and sell one for some money if a year or two

[Addissimo]

check your pm stu

[Beej '86 325es]

Yes, what Stu said about the filleting the internal corners is important. I'm an aircraft structural design engineer, so I work with aluminum constantly. I work in SolidWorks as well and can help out with this type of stuff too. If you want a second eye looking at this, send me a copy of what you've got.

thnx

[joshh]

What do you guys mean by filleting the edges or corners? Would this be adding "ribs" to the inside corners?
