Oodles of weasels....man, I was just thinking about that on my way home from work today when I heard this noodle commercial on the radio.

Cool, so get a drill press and some good cutting gear.

I jest...that's not mine. :)
...but I have seen the aluminum metalworking live and in the shavings, so I know what you mean.
Home depot, here I come.

Now that is just sick. Someone is having way toooooo much fun there. Nice shop whom ever it belongs to. I wonder how much time is spent playing in that little hole in the wall.

I've spent days down there prior to each of the final 3 seasons of battlebots.
An old friend of mine used to run a superheavyweight bot asked me if I wanted to help him out. Sounded like fun, so I figured why not.
I'd help him tear it down, clean it, solder stuff, put it all back together and operate the weapon during competitions.
He spent most of his time doing complex math and milling heavily lubricated 6061 and 7075.

The jet was just over 10 grand, I think...
DooAll here:

was about 30...grand in parts and materials.
The speed controller alone was about $2,500.
375lbs driven by 2 wheelchair motors in the trackpods being fed with 6 plates of 18x3000mAh panasonic nimh C-cells.

It actually ran better on the older gel cells, but they were fairly heavy.

Anyways, to bring it back around to the topic at hand...I don't have this guy's budget, so I'll most likely have someone else craft a motor mount for 1/2 the cost of a cheap drill press.
I like to keep the material posessions to a minimum if possible and don't see myself needing a drill press before, say, a decent makita or something a little more useful to me ion a daily basis.

Where do you folks think I should start with the pinion and spur? Currently I have a 70 tooth(I think) RRP spur. I was thinking about going with maybe a 13 and a 17 tooth pinion for starters and after runing those, maybe have a better idea of what's needed if neither of them will work out.
