Re-Drilling BLANK front hubs from Rodney Dickman (Page 1/1)

I have a BLANK set of front hubs from rodney dickman I need to get drilled in the 4.75 corvette bolt pattern. There is nowhere nearby my hometown to get them done so I was going to maybe attempt them myself. What would be the best thing to use as a drill guide for 100% accuracy. Or better yet if someone had the means to do it id be willing to pay for your services.

I found this on google: http://midshoremachine.com/

Anyway, if I suppose that you've already found them and considered them not viable for whatever reason...

I would suggest a brake rotor (with the appropriate hubcentric ring) as a drilling jig. You may want to press drill bushings into the rotor's holes.

I hope you have a drill press and not just a handheld drill.

The holes should really be drilled on a vertical mill. I make a fixture for the 88 front wheel bearings way back when to lock the bearing/wheel flange in place, dial indicate it to the mill head, then drill the 5x100 pattern with the DRO from the mill. It just takes time to get it setup.

I am not sure if the stands would be tall enough for Rodney's new bearings as the housing is extended.

If you used a Corvette brake rotor as a guide and use a drill press plus proper procedure and a little skill, you can do it.

You'll need to use the Corvette rotor as a guide. You'll need to transfer punch, center drill and pilot drill every hole before you try to size drill it.
When you clamp the rotor in place, you'll need a centering ring to correctly locate it. Also make sure that any chamfers in the lug holes in the rotor are toward the hub, in order to correctly locate the transfer punch.

Yea I was thinking of getting a used rotor or spacer. Then find the right size hubcentric ring to center it. Then just have to get ahold of the transfer punches and drill bits. Thanks for all the replies keep em coming.

I haven't ever asked them about redrilling hubs, but I have used them for a lot of odd stuff before. J&B machine shop in White Marsh/Nottingham MD on Philadelphia Rd. They do a lot of Pro stock stuff and I have had them even do dirt bike engine machine work.
