That first design I sent you was based on the slipperential. Here's some dimensions for you.

The slipperential does not come with bearings so you will need to supply your own.

That's perfect Jason!

Hopefully I'll get some time today to do some modeling.....unless real work gets in the way!!!

Progress?

Gee · 02.28.2010, 10:31 AM

This is great Jeff. I bought an lst2 a few months back have thought about letting it go since I got the baja but I think I will hang onto it to convert someday. Did you get rid of your Hellfire?

JThiessen · 02.28.2010, 02:31 PM

Yeah, I have the top plate configured. I'll post some pics of it this afternoon (gotta go grout my tile now). I need some feedback on what i've got.

Guy - yes, I still have the hellfire. I've robbed a few parts (bearings and links) off of it here and there, but its pretty much still all there. Want it?????

So here are some pics of where I'm at so far. Didn't get anything done on it today - the grouting took longer than I thought, and my daughter and the grandkids are on the way over now.

Top view

Side view

Iso view

So I'm currently looking at making some smaller CD mounts that will mount to the lower tray (which I didn't model up yet). They are flush with the top of the chassis - I might be able to tie them into it also instead of a plate tieing them together.

I'm thinking of trying a mount set up similar to a flux mount - two straps around the motor, and they would mount to the upper chassis and be slotted side to side. But, this wouldn't put the motor in direct alignment with the spur...not sure if thats going to be a problem or not.

I think I'll extend the upper chassis plate to one side to give me a battery mount location. Or, if I can get dimensions for the XXL, that might give room to mount it on center...

looks great so far

JThiessen · 03.02.2010, 07:03 PM

I'm thinking about offsetting the center diff to one side now, similar to a truggy alignment. Not sure if the CVD cups on the LST are any different to be able handle that angle - anyone know if there's a difference?
Sliding it over about a half inch will allow me to drop the motor down some more into the "tray" area.

pinkpanda3310 · 03.02.2010, 07:14 PM

Here's an idea, invert the motor and diff so the diff sits above (but still 45 degrees) the motor. Then you can mount the motor and the batteries on the lower plate. It's a concept I toyed with but never thought to offset the motor.

Gee · 02:01 PM

I would like the Hellfire, but can't right now. Need to do some thinning of the herd first.

Before I bought the lst2 I was gathering parts from the chop shops to build a xxl. It will be a while before it takes shape. Would be happy to lend you the xxl chassis and/or any of the other parts I have so you can look at, measure, remeasure, stare at, remeasure, etc. all you want. I'll need your address again though.

That is an idea....I had also been thinking about a possible method of mounting the battery from below - that would keep keep me from having to remove the lid to change batteries. But there are complexities around it that kinda make me keep from wanting to pursue it - if I had a 3D printer locally, I could make some cheaper parts for test fitting.....hmmmm....have to check into that.

Hey, that would be great. Just need the chassis and side rails I think. Not sure if the end plates would be any different.
I'll be coming through Spokane on the morning of the 27th and back through late on the 4th of April - I could either pick it up then, or drop it off. I'll PM you on this, and send ya some postage money.

I ordered the slipperential and gears last night (thanks to my in laws B-day present!!). Went with the 52 tooth gear and a 10 and a 12 tooth pinion. 1:1 rollout is probably not attainable with this system - I'll be sitting at about 1.7:1 or there abouts......similar to how a Flux is stock.

The old lady is heading out of town for the weekend, so unless I find a cutie to drink with, I should get some time to get some concepting done.

Gee · 03.06.2010, 12:06 PM

Jeff, I found your address and almost put it in the mail yesteday but thought I better make sure you haven't changed addresses in the last year and a half. It's out in the truck but I think it was 1100 something. If nothings changed I will send it out to you.

JThiessen · 03.06.2010, 12:53 PM

Hold off for a couple days - I put a bid on a new chassis on Flea bay - might end up with it for the same price as it would cost for us to ship. If I get it, you can have it when I'm done measuring it.

ps. Yes, sounds like you have the right addy still.

JThiessen · 03.07.2010, 10:10 PM

Didn't get any CAD work done today like I had planned. I think I want to get the Muggy up and running before I make my final decision on going center diff on the LST......after thinking about it, I'll end up with basically the same damn truck if I do the conversion with a diff.....

So I started pulling the Muggy apart: Removed the CD and tried to fit up the 8T RCM mount, and found a few differences - mounting holes are different, the centerline of the diff from the tray is different, and the bearings are bigger. So, I put in an order for a Muggy/Mayhem motor mount, and ordered one of Mikes large battery trays. Lots of room on the Muggy, so it should be a straightforward conversion. I'll probably have to shim up the battery tray to clear the screws holding the mudguard in place, but that also should be easy.

While looking at the Muggy, it doesn't appear that it would be too hard to make a long center plate that would also capture the center diff to stiffen things up. Or maybe even some turnbuckles. I think I want to get the Muggy up and running before I make my final decision on going center diff on the LST......after thinking about it, I'll end up with basically the same damn truck if I do the conversion with a diff.....

JThiessen · 03.09.2010, 10:45 AM

Well, I scored some LST2 Flextek arms, Lunsford pins/turnbuckles, Ti Plates, and AL bulks today. So it looks like the conversion to the LST2 config is set. Sweet......
Now I have a set of Hardcore racing arms for the original LST that I'll sell to anyone that wants them.
