Double hole saw thing...

Couldn't you just chuck it up real quick and make a tiny center mark in the beheaded bolt and walk a compass around it? Seems like that would only take 15 minutes a peice if you did a bunch of them at the same time and had your machines/compass set up for them.

I'm wondering what peice of tooling are you talking about.....

You have my attention.

I suppose you could do that. They'd still only be as accurate as your eyeball which I could do now.

The piece of equipment I'm watching for is called a rotory table with horizontal and vertical mounting. Not the kind of piece I "REALLY" need. I find myself wanting to use one from time to time. Just not that critical. I could build fixtures to do the same thing for this, its just slower.

I'm not sure what you guys are really talking about tho.. I did ORD's FUSH kit on mine and barely had to remove much material, maybe an 1/8th all the way around... did it with a alum cutting carbide burr in about 5 minutes per hole...

I did Kert's and yup, 5 minutes with a cheap crappy grinding stone in my die grinder did the trick. I would guess 1/8" diameter difference, so 1/16" all the way around. The grinding stone, however, did not survive.

I guess some sorry saps aren't as lucky...

Slick idea though. I'll have to remember that.

When I had to open up some rims center holes from 2-3/4 to 3-1/4" so they would fit over larger hubs (on a tractor I was adapting them too),I used a peice of 3/4" plywood bolted to the lug holes to block the hole up, so the hole saw's pilot drill had something to drill into--but after I drilled the center hole I removed the pliot bit and used a threaded rod bolted to the plywood that fit where the pilot drill went as a guide pin..worked very well ,good enough for what I needed to do anyway..

After doing 2 rims,a friend who had a 1" to 3" tapered pipe reamer brought it over and we hogged out the holes on two more rims in about 10 minutes,we just cranked it in from both sides,and used a carbide cutter in the drill to "square up" the hole..
I thought about using a ridge reamer ,but didn't have one available,bet that would have worked too,though it might have been rough on the blades..

using that keyless chucked drill would get on my nerves REAL quick.

Good idea though. I'll remember this ...maybe

Normal drilling operations its OK. Vibrations really make it loosen quick.

So we murdered my CB Cable with the propelyne for nothin...

I am not very tool smart all the time, can you take the contraption apart and lay it out in expended view so I don't feel so retarded?
