I just need another lathe now I spend a lot of time resetting or I put my lathe work on hold till I get a break between set ups .

Sounds very interesting!
Got some pictures of the parts?

Steve , I have a tool post not the aloris brand I begged for that a long time ago when I was in my dads shop . as for chucks I would have a bunch but , I can't get the right thread for the adapter plate . I need to get 1 made for my 3 jaw

I was just ready to make my back hangers for the front springs , I need another .25 " end mill I don't think I'm getting HSS any more Well I did get some more done front springs and center webbing for the rear . I'm hopping to start on axle housing this coming wknd ,wife has plans on sat





OH Scott , I put the trans in last night I put the gears I had from travis' ( bigger bull gear and smaller pinions ) motors run great

No I did not stop I got some nice end mills yesterday and spent last night and tonight making the front axle and rear spring hangers for the front .
I also got some aluminum flux for welding aluminum with the torch and it works real well . So looks like I'll be making the cab in aluminum works just like brazing
I hope you can see these

That trans should motivate it well. That is one beefy machine!

Get more chucks for the lathe and a Aloris toolpost. Then you can switch out a chuck without disturbing a setup and leave a special tool in a holder.

WOW Steve this thing is going to be a monster..keep up the great work..

[tracksntreadslou]

Looking Really good steve..Making good progress..Those diffs are looking like they will be bullit proof.

[td9clyde]

[kerst]

I like the way you made the axles! very nice work!

Steve. Great gob on the axle. How do you plan to hold the joint together, setscrews or bolts. She's going to be heavy duty, that's for sure

thanks guys

Rob , I'll be using 3mm bolts which I still have to mill bolt areas on the flang once they're bolted together then chuck them back up perpendicular and bore for the pinions that'll be a fun setup

Awesome work, Steve. I am looking forward to seeing the updates, as they come, which is usually what I reply to all of your posts! You have a lot great project builds going at once. I can't believe you get as much done as you do. If I even tried to do what you do, it would take me a lifetime, probably.

I don't know Nate , the new/old cnc mill has me occupied right now to get it going . Oh thank you

[sneaky-pete]

Nice work as always Steve.....keep the pics comming!

[steamer]

Steve. Looking forward to pictures of that setup.

This truck is really looking really good. I understand you are running twin motors with different-from-stock pinions and driven gear going into the transmission? Would appreciate some detail on what gears you are running and did you have to build the two-motor bracket.

Thanks!

Ken It's an E-max tranny they come with 2 motor set up . The best guy to tell you about what I have would be Travis . I'm kinda trusting his jugement on the motor trans setup . If it works and has what I need for the pan , I'll be putting these in them too . I like the 2 speed idea .


thanks Troy
Rob the set up will take longer to true it up then to cut . If I get the CNC mill working , it'll be easier on that then the lathe , I'm thinking . If not then in the 4 jaw .

Just awesome work on this Steve. Looking great!!

What specific flux are you using on the alum?...was thinking about giving this a try...but not a welder. How hot we talking...do I need real tanks and torch or something that could be done lower heat like w/ little coleman propane torch?

Joe

[ihbuilder]

thanks Joe B. , On the thin sheet a little propane will work but .125 and up gota use some heat . I got alumna flux at the hardware store made by forney and thought I give it a shot . you just got to watch the heat on the sheet , you'll warp it just like steal . It's hard for me to explain how , since I do it by feel . I only messed with it on some scrap , so we'll see how I do on the truck

The Emaxx tranny is a beautiful thing. I use them for most of my trucks. Are you gonna keep the 2 speed or make it a single speed? There used to be a conversion kit that almost cut it in half and basically locked it in 1 gear. I think you can still get an aluminum tranny case for it as well. Make sure you don't over tighten the tranny mounting screws, they strip out easily.
