Not sure how much Mike charges, you'd have to contact him directly. The only other company that used to make custom length dogbones was RCAlloys but they stopped making parts a couple years back sadly.

Usually though, guys go on a scavanger hunt to find dogbones from other vehicles that may be useful, then they work out the position of their CD or tranny based on that..

One other question. Do you or anyone else knows what type of counter sink drill bit I should use for the holes to get them flush with the plate? I don't want to mess that up and have to buy another skid plate.

suicideneil · 07.10.2011, 06:10 PM

Just a regular countersink bit with a 45* angle on the cutting head/ teeth- the important bit is not to drill to deep with it, thats how you avoid the head of the screw being too sunk too deep. I would practice on some scrap metal or plastic and then you can set a depth stop on you drill as required.

I can't find a countersink bit for my dremel. So do you think this will work?

I have a countersink bit for my drill, but it won't fit in my Dremel. I also have the Dremel drill press attachment. I think I will have a better result with the Dremel/press attachment than trying to do it freehand.

I dont think the router bit is intended for metal really, it'll probably go blunt very quickly, if it doesnt shatter straight away. I wouldnt try doing it free-hand either, no. I would look/ ask around and see if any of your neighbours or friends / shops near by have a drill press you can borrow.

Good news, My neighbor has lent me his drill press. I should be able to work on it in the next few days. On a side note I found an interesting product. It is a Dremel chuck that has been modified to accept regular drill bits. I'm sure more than one person here might be able to use one of these.

I ordered one I will let you guys know how well it works.

So also was thinking about using a tap and die so I could thread the holes in the plate. I was thinking it would make the mount a little stronger. what size would I use?( thread count, size,etc.....). Is this more trouble than it's worth or do you think there would be additional benefit?

cmac · 10:21 PM

I just got the Slipper mounted. Never mind about threading the hole. I don't think there is enough metal to really do that. I'm just happy the I got the depth of the countersink bit right. Next I will need to find out how long the dog bones have to be.

A few more pics.

Bleh, I would have said use a 2.5mm drill bit & an M3 tap for doing the skid plate to mount the CD unit, but it wouldn't add much strength really no- just be sure to use blue threadloc on all the screws for final assembly. It is looking very good so far, you can always touch up the chassis where you had to notch it using a red sharpie or even red lip gloss ( semi transparent effect like anodizing, so that you can see the metal surface texture but it is coated red ).

cmac · 11:40 AM

No, Neil I only do things one way. After I get it together I will send it back to the shop to get it re-anodized. The turn around is only 2-3 days, and they will only charge me 25 to 30 dollars. Thanks for the compliment, I really appreciate all the guidance so far.

cmac · 07.13.2011, 11:45 AM

I realize that the chassis is going to get scratched so I think I will get it re-anodized from time to time. I have a few more parts that at the anodizers right now. I don't plan on running it into a tree, but it is not going to stay on a shelf either.

Cmac - I am really enjoying following this build. I have been looking for a thread with someone putting a slipperential in an Emaxx - finally found it.

What motor mount are you using? Is it this one....

Your truck is looking awesome by the way.

cmac · 07:51 PM

Thanks, thirdcliff
yes that's the mount. I've got a lot of cool things that I'm about to bolt on in the next few days stay tuned....

thirdcliff · 07.13.2011, 07:13 PM

Oh, I am subscribed to this thread - don't you worry!

I am going to build an emaxx and have been lurking off your thread and others to see just what type of setup I want. Still researching...

But I did pick up a FLM chassis, hybrid bulks, shock towers (pretty much your setup) and some HB diffs - still waiting for the 43t diff gear (HBSC8028) to swap with the spirals that came with mine. Damn things are sold out EVERYWHERE.

But I can't wait to hear how the slipperential is in the maxx. It just might be my next part....
