Bomb-Proof LSP mount

[squeeforever]

Hey guys, as some of you know, I've had a BPP LSP for a while now, but haven't ran it but a very little since I need to get a center diff mount machined for it. I've been playing around with eMachines Shop and this is what I've come up with. Any comments, suggestions, criticism is welcome. I still need to change it up a little and design the front. I think I might design it to were I can have a top plate to connect them like a standard diff, but its really not necessary. If I do, it'll probably be out of CF. On to the pic...

wanna sell that BPP LSP Squee?... :) did you design that urself?.

[squeeforever]

Nah, I don't really wanna sell it to be honest. Its not something I can really replace. And its probably the best handling truck I've ever seen. But yea, I designed that mount myself for it. I changed it a little bit more since last night. I dunno if I should make it have a top plate or not....

That is nice. Here is what I've done so far. It has mount spacing for the 22 and 30 series Lehner motors.

Like you would ever need a 30xx Lehner in any kind of R/C truck...

[lutach]

Well, I would like to have one LOL. For me the more the better. A 3040 would do just fine. It would make my BPP go .

Yours will be impossible to mill Squee; the straight edges are near impossible

And there isn't much room for the screws to mount it either. Not enough meat.

Mind elaborating? Are you referring to the bottom? If so, I'm gonna add more meat down there, and/or use a top plate as well. It doesn't really look like that now, I'll put up another screen shot tonight.

If you give me the dimensions, i am more than willing to help you out, and show you what i mean.

The bearing support through hole is too small; It might be hard to get the drive-cups trough. A 1mm smaller hole than the actual bearing hole would be fine.

Ok, thanks Serum! Dimensions don't really matter. Simply a diff mount for a HB diff using a Kyosho spur, with pinions ranging from 9 to 24 (all available mod1) with the standard motor holes and all. The bearing support through hole is 13mm and the other is 16.2 I believe. I figured 1.4mm on both sides was enough, but not to much. The BPP mounts hole is pretty small, but thats a Ofna diff.

Okay, 16.2 for the bearing is way too large! A 16mm bearing is 15.96 mm od, i thought Mike makes his bearing holes 16.06 or such Hang on, i'll draw you a plate.

[zeropointbug]

I usually make bearing holes for bearings that size roughly 0.05mm larger than the bearing OD. Also, I agree, I sometimes make 0.5mm lip for the bearing hole, it's enough, really. About the internal corners, I make mine 3mm diameter, or 1.5m radius fillet.

[squeeforever]

Alrighty. I've talked to people before about the bearing hole, and thats what I was told, but I'd believe Serum over just about anyone...

How about something like this?

[squeeforever]

Should have mentioned the motor has to be in the center. That looks REALLY good though. Think it could be changed just a tad to put the motor over the diff?
