I now have 2 of 3 profiling operations completed.

I now have the profiling operations completed
And I'm now machining the axle path!

Axle path is now done and I'm currently machining the gear path @ 2.325 x 1.485 @ 65 IPM

starting to take shape nicely. you running a diff or spool?

Mudgy

Looking good mate... didn't you have a sheet metal diff case before?

QSPSB2

Thanks guys. I'm going with a spool for this one. I may eventually machine an actuall diff..
Yeah mudgy I did make a sheet metal one a few years ago.. It was made from 1/8" steel and weighed a ton and wasn't precise at all.. This one is very precise I have about 0.0003 tolerance and that's just because I got about 0.0001 backlash on X&Y I got backlash compensate dialed in in mach3 but I'm still out 0.0001 no biggie..

The gear cut path is now complete, the spotting/drilling operation to secure the faceplate to follow!

hi mate, liking the start of the rear end, should be good and scale looking when done, i read you built a sheet diff, this is my current effort , some where to start from, it runs a mcd diff unit

long boxed trailing arms and a multishox set up for my trophy truck build

QSPSB2

Thanks.. Yeah this fabricated Rearend should make the Beretta look like its all business from the rear view.. That one you built looks pretty cool man.. The other one I built wasn't actually made from thin sheet metal. It was built from 1/8" steel,, I attached a few pics of both..

hi , the steel one looks tuff, mine was made out of 2mm sheet cut and tacked on a jig, runs pretty true but weighs a ton

I recently purchased some decent shocks for the Beretta. The shorter ones which I'll use on the rear are
Ready to be bolted on.. Once I get the Rearend done. The longer ones I'll use as struts on the front, I'm going to
Remove the lower spring and machine a sleeve that will secure the spindle and brake caliper mounting bracket.

Hey all, it's been a bit since my last post. Well I recently replaced the Z-axis thrush bearing on the mill and have yet had the time to drill/tap the timing pully mount. Will be here soon. However. I do now have the majority of the beretta components and all the electronics. Picked up a turnigy 9XR radio, 4-1/4 scale steel geared servos, fail safe, RX module, battery's & chargers. Lights. 4 wheel hydraulic disc brakes. With two master cylinders. One for the front, which will lock up the fronts for burnouts. And one for the rears. The primary brake.im currently re-designing the front upper strut mounts and struts.

Very nice! I am becoming more and more infatuated with these large scale projects. I am particularly interested in the metal beretta body. Do you have thread on the construction of that?

QSPSB2

Thanks. I have a few videos on it on my YouTube channel. Can't post link here from the iPhone but you can just search QSPSB on YouTube and that'll work!

But for gods sake, you got a whole thread about it [link=http://www.rcuniverse.com/forum/m_8763882/mpage_1/key_/tm.htm]here[/link]

So how's the rest of it coming along? You must be pretty close to paint now?

QSPSB2

Nope... I've nearly got the hood ready for primer but that's it. I haven't even started the body work on the body yet. nor have i finished the metal work on the front bumper/ground effects.. been working alot of hours and had some serious clutch / pressure plate / throw out bearing issue with the stang. I don't even have the time to address it so my buddy's going pick it up and fix it in a few weeks.. I may even have the engine rear seal replaced as well.. It leaks ... Typical ford.. so i went out and purchased a half way decent used vehicle. A 2002 Monte Carlo LS.. a super clean one owner ride.. I'll update the Beretta build as I progress.. Thanks for asking!!
