9 Foot Power Truck

The HP E7 gets a new drive system based on the same tower design. (Isn't this where I started here? :think: )
This one has a NWSL 2032 motor. It has one shafts/flywheels cut off from trying to stuff it into an F3. I'm going to try one of the Kato HO HM-5 motors and see how they run, though it would be hard to improve on this setup. Once I get a weight made up for it this will be a nice smooth runner.

The first pass here is at 6v, the second one slows down to 1.5v and the third is at 10v.

Yep, regular DC for the power.

The E7 was made by H.P. Products way back when, http://www.ttnut.com/hp-e-7-t307.html

My machine can't mill brass but making the Bismuth weights is pretty easy.

The spindle (Kress 1050 FME-1) is made for milling but the machine isn't rigid enough. I have done a few small milling operations in aluminum but wouldn't want to do any extended runs.

This is the same spindle I'm using.

Looking really good Rob. Which parts exact are made of Derlin?

Just the gears inside the case are Delrin.

Just need to raise the motor up a bit & make up a small weight and these will be ready for sale also.

I'll need to run these in batches for machining the chassis. I have a jig for holding the chassis but setting it up and getting evarything squared up is time consuming.

Watching this with great interest... I'd like a good chassis for the GP and F3 and I'd be *all* over an FT!
