Hey Lynn, I've had good luck with this program opening .dwg files. Case in point you have to have it for the Western Star body builder download's (zipped).
Yer welcome, Neil#2 aka doodlebug

Re: Mack M75SX
 

Coming along very nicely ..Im pretty amazed at how fast you build these things steve..and with all the other work you have lined up its good see your making time to do your own stuff.
Hey steve what are your plans for diffs for this brute?..Looking threw my spare parts box i came accross some tamiya Mammoth/juggernaut diffs that look very hefty..they are top drive and with a little mods i think you could make one with a rear output as well..

Re: Mack M75SX
 

Lou , I'm actually going to make my own drives using HPI savage internals . I got the spools and pinions and I just ordered my bearings . I got to the point ( finally ) to work on others parts to a certain time then I work on my stuff . 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 .

Re: Mack M75SX
 

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.

Re: Mack M75SX
 

Sounds very interesting!
Got some pictures of the parts?

Kerst , I'm Making mostly Wheels right now and air cleaners and fuel tanks . I have pics in IHB in the vender section .

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 :mad: 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 :(

Re: Mack M75SX
 

No I did not stop :p 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 :confused:

Re: Mack M75SX
 

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

Re: Mack M75SX
 

Boy you learn fast! Great looking work! I stopped getting HS tooling quite awhile ago. Carbide is more expensive but lasts much longer, so it's a fair trade off. My shop time has dropped to about 0 after knee surgery. And to top it all off, I think my Sherline mill is in need of new gibs. Really not bad after 20+ years of use and a new bed.

Re: Mack M75SX
 

OK, you will say I'm a "rivets counter", but the M75 had a tubular front axle ! So I propose you to send this one to me (will fit perfectly for the LRVSW) and make a new one with the correct design :D:D:D

Re: Mack M75SX
 

I know ,Papy :p I sometimes throw my own twist to things :rolleyes: the body is off a lil to :confused: I think I got the rear taper to long . I was going to do the tubular axle but I just felt like milling an I beam front . I may do another but as a tractor but thats a lil while yet . I think I got enough going for now :eek:

Re: Mack M75SX

Re: Mack M75SX
 

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

Re: Mack M75SX
 

nice work that mack is gonna be huge when it is all done

Re: Mack M75SX
 

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

Kerst

Re: Mack M75SX
 

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
Rob

Re: Mack M75SX
 

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 :eek:

Steve

Re: Mack M75SX
 

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.

Re: Mack M75SX
 

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