i wanted to use just the 203 range box then to a np 200.
so i took the chain case off pulled the rear output shaft and turned it down for a 32 spline yolk.. then cut the shaft off..

once i got the splines done i melted some aluminum to make the bearing retainer..

Hell yea! Damn impressive :beer: oh and yes I am jealous too.
 
yeah that is badass! How much time do you have in this?
 
What did you do the splines with? What is it going in?
 
I'd like to see some details on the resplining if you have any. I've always been curious how a home machinist could accurately do that. Maybe a good link you could refer us to? Thanks?

x2 that is kinda what I was wondering too.
 
he is going to run an np200 behind this. they are basically a np205 with 2 rear outputs. you can mount them vertically and really lower your driveshaft angles.


thanks eric

im useing the np200 for a big azz truck lol
it is a rodeo with 2.5 ton gmc eaton axels
500 cadi th350 203-np200 on tractor tires.

i resplined it with a cut off wheel & die grinder
witch was a pain in the azz ...

thanks guys

Ye Gods...I really didn't expect that. I've got to say that wouldn't have occurred to me to try it that way. On the other hand, I'm not really sure how else you'd be able to do it without a vertical mill. I'm pretty sure I could spend two weeks cutting splines like that and not make anything more useful that sparks and dust.
 
thats why it was a pain..
the lathe i got is also a mill and drill im going to get some scrap an experiment see if i can do splines on there
should be alot easier..


thanks guys:driver:
 
any more details on you do the alum. forge stuff. Alum. selection etc? any detail be cool.
the best way i have found to melt alum is in the stokermattic
i use a small cast iron pot.. get the fire going and put small pices of wood arrond the pot makes for a hot job..
the alum u can use pistons, broke trans housings,t-cases
pretty much all alum basides carbs and chain saws
they gotsome outher metalin them that dont melt to good..
ill get some pics as i melt some next time..
thanks

Interesting. I've had my eye out for some machining equipment, but frankly I just don't know enough about it to even recognize straight up junk when I see it. I've heard a lot of guys talk a lot of shit about those combo machines and say that you really need to get stand alone machines, but damn that costs a LOT more in terms of both money and space. I have no doubt that from a purely machining point of view that they are correct, but seeing you turn out impressive work like this on a combo machine makes me rethink that advise, particularly for a guy like me who is looking to just get his feet wet in machining and see if I enjoy it. What kind of combo machine are you using? Got any pics of the whole machine?
