And here is the installation of the CD and motor mount:

I'm using the Muggy CD mount with 1/4" spacers underneath for clearance with the 50t or 54t spur gear.

Nice work Brian, it's looking good.

Nice work. Looks like you lucked out with the way the CD mounts have horizontal threaded holes so you could drill through the aluminum and bolt it up. Or was that planned? :)

Those are the holes to mount mechanical brakes (all CD mounts have them). Since I'm not using mechanical brakes for this build, they are very convenient for aligning and attaching my motor mount - I used them in the same way when I converted my Muggy with an Al-angle motor mount.

Brian- I did some cutting on 6061-T6 alu .250" thick yesterday. I used a Ridgid jigsaw (AC110 power) with a metal blade. This combination was great and cut through the aluminum like butter! Plenty of control on the blade, pretty perfect cuts too. Much better than my metal band saw.

Build is looking good so far too!! Love the Hummer body.

If I have to make another long cut I may have to pull my jigsaw out and pick up a good blade for it (I'll admit the long 24" cut with the hacksaw was not fun :wink:). For the small cuts I'm making now, I don't mind the hand saws.

Looking good it makes me want to order some aluminum For my own project

brian this looks very solid! nice work!

Just wondering... do you buy the alloy with the 90degree bend or do you bend it yourself ???

I think this is the same as what I bought a while back and has lasted me a few projects:

Edit: here's the right one:

I was considering a few options for what to make my battery trays out of - I think I'm going to use what I've used in a number of other vehicles:

PVC u-channel

The price I see on Amazon right now is very low - I bought a bunch when Amazon had it even a little cheaper. I want to fit these batteries in on their sides:

and my 5s packs of the same capacity are 41.5mm tall (a little less than their specs). So I sanded down the inside of one leg of the u-channel with my dremel drum sander - and the 5s packs are a perfect fit:

I still need to cut slots for the battery leads and then I can lay them out where I want them on the chassis. I plan to run 2 6s packs in parallel.

I just ordered a pair of the Gens Ace 6s packs I linked to above - Hobbypartz has a bunch of their batteries on sale - these are 20% off - so cheaper than what I paid for my 5s packs.

Looking good. I'm loving the sturdy motor mount. I did something similar with the "feet" on the sides of the CD for my 10yr old nephew's Mayhem ST, just wish I had more room on that truck to make them bigger. It holds up to his bashing so I guess its ok. Hopefully this winter I'll get to start on my LST based 1/5th, till then I'll be watching and collecting parts.

How did you make your slots in the L channel?

I just drill a few holes with the drill press as close together as I can get them, then I use a file or dremel w/carbide bit to remove the rest of the material.

Cool thanks.

I've been considering purchasing a mill, but even for the small X2 benchtop size, I'm look at well over $1k for it and tooling. I wouldn't be using it often enough to justify the price. Finding ways to make stuff without it is my mission. You've definitely shown me a few things. Thanks
