Hi,

Does anybody know where I can get the spec sheet (at least the measurements) for the drill motor gearbox? Any info would be appreciated.

                Thanks,
                    Eric

Eric,

What spec do you want?

I can tell you that the I think the drill spec claims that the drill can provide 250 in-lbs of torque.

The ratio in low gear is about 60 to 1 and the ratio in high gear is about 20 to 1.

All that the info (probably more accuately reproduced) in in the manual.

Good Luck,

Joe J.

Well, he’s with me so I’ll speak for him. We’re looking for dimensions of the gearbox so that our HS students can make a motor mount with CNC. We can do something that fits fairly well by simply using calipers but if we want all the holes to line up perfectly, we’re gonna need some specs I think. Do you have any dims for thos guys?

Calipers is the closest think we have to the print. Perhaps others have better.

This is another aspect of engineering, reverse engineering. Trying to figure out what the other person was thinking by looking at the part they made
