3-ton Dake press $400 Victoria

Just out of curiosity here, could a guy take a 1/4" endmill, chuck it in a cordless drill, walk over to the bench grinder, grind the tooth profile in it and use it like that to cut rack teeth?
 
Here's the tooth profile on the ram.
It's involute'ish.
I'm thinking that I could use my D-bit grinder to make a single flute cutter.
After all, it only needs to cut five slots.

Luddite again. As you say, it's five teeth. By the time you make a d-bit, and figure out how to set up to cut this in a mill, or buy and renovate a shaper (even at the speed David works), it's still going to take longer than using a file.

Make a brass tooth template, cut out the centre slot with a hacksaw, file to rough profile, riffler file to complete to match the template. It's five teeth, the rack moves in inches per hour, not very often, and not very far. First tooth will take you an hour, second and subsequent teeth will be five minutes each.

Inches per hour...ok that made me laugh out loud
And yes you have a point... but don't I need another project to slow me down?

From my point of view, it's worth trying. Precision may not be that important for this job. I'd be making the whole thing out of a steel billet though.

What is your point? That's EXACTLY WHAT IS NEEDED HERE. We have to slow that guy down! Him buying that broken arbour press is the best thing that has happened to the rest of us slackers in a very long time!
