Mack LRVSW
 
Sorry, just did not notice the server change, so have to re-post here :rolleyes:

I started this project long ago to match my 88-B shovel.

The LRVSW is a direct ancestor to the famous M series off-highway trucks (see IHBUILDER M75-SX)

http://i48.servimg.com/u/f48/12/58/20/29/dscf2910.jpg

Comparing a Tamiya standard axle to the modified one I will use gives you an idea of the size of this baby (they are supposed to be same scale !)

http://i48.servimg.com/u/f48/12/58/20/29/dscf2914.jpg

The LRVSW was basically designed to be a dumptruck, but some of them have been used as logging trucks. Eventually, a couple were later transformed to be used as prime movers for heavy haulage work....

The model will be around 10kg empty (22 lbs) and will have a GVW of 21 kg (46 lbs).
I will have to fill the tires with some serious foam, as the original material is intended for lighter models and is a bit too soft.

Not sure I will keep the Tamiya gear box, but in that case, I will certainly add a 3 or 4:1 reduction gear.

Now I see this truck on the CURRENT web page. I was puzzled by why my posts weren't showing up from one computer to another!
Glad to see another vintage off road dump being built. Like I said before that didn't show up here; "That will look nice with a certain 88B's 4cy dipper loading her up" Or, a 10cy dragline but you 'll have to bring it to the USA for that to happen.
Steve, You better get your Mack together.

Good start to a fantastic looking truck!

Forgive me if this sounds dumb......but how did you spline the ends to fit into the diff or did you slide this over the existing rod? (i am no machinest)

As a "no-machinist", I must say your work is rather impressive ;)

I just kept the original shafts, drilled my additional length 0.2 mm less than the external diameter of the splines and "forced" them gently over the existing splines. I used the lathe as a press to maintain everything centered and avoid any bending. Not sure my explanation is clear, so I can take a picture if needed.....

Did you use any Lock-Tite as an extra security to your press fit hub?

You get that trk done & I'll have a job for it. :D

Re: Mack LRVSW
 
No Lock-Tite.....

For the job, you'll probably have to wait a couple of years.....or a couple of decades :D

Great build going. cant wait for more updates. like those front rims did you build those?

Papy 07-19-2011 02:47 PM

Re: Mack LRVSW
 
Yes, the rims are custom made. Two full buckets of metal chips :D

Exquisite machining skills Papy, continuing detail work like that & it could be decades, I suppose. :D
