I am.... always...




Ok got it...

Before getting a $30, 4-3/4" hole saw, I searched tons.... The great hole saw technique sounded so good, but after just touching the wheel with my "hole hawg", I knew this is WRONG with no center pilot as a guide. Two skips later, and some NICE changers in the rim later, I threw it in a BIG drill press. Slowed it down as slooooow as it would go, drilled the rim out, and mic'd. 4.77". Yes, it would squeeze over the hub fine. Tight, almost hub-centric... I did not feel that a hole saw'd tight fit was very true. almost like I made a hub-centric rim I couldn't say was center... I was not about to bust out a file and try to remove about .030" out of 4 rims..

If everyone out there want's to say "yeah, grab a big drill and a $30 holes saw no PROBLEM." I feel it is very misleading. I tried it, and wish I spent that $30 paying my machinist..

THAT'S JUST ME THOUGH AND I NEED TO RELAX...

Done with this thread but I feel better telling my story as it's not as easy as other "think" it is..

I used my diegrinder and my non-ferrous carbides. about 6 minutes a rim. No its not perfect, yes it works fine. I don't know what the big hubub is about.

Wet, you must have your answer saved by now and just copy paste it, good advice


Here is a link to a wheel sketch

For those of you worried about center balance machines, notice that (in this method) the existing wheel edge remains on the front side, so no problem for front side attaching, the jpg does not show the cone on the rear, but its there so no problem for rear side attachment.

Its not rocket science, I used a router done in 10 minutes. No need to remove and remount the tires like most machine shops need to do.

Me and a guy from work both did ours with the grinder no problems since these wheels are LUG CENTRIC saved my money on dismount, remount and balance. NO PROBLEM

HAHAHA I get it great word.

Hahaha, I came up with that one all by myself too



but seriously I buzzed mine with the 'ol die grinder and Mac aluminum carbide.

I've watched every one of the wheels on every vehicle I've owned get mounted on the balancing machine from the outside of the rim.

I've been working with metal for 3 decades now, and I wouldn't want to go after the wheel centers with a hole-saw!

I don't recommend it unless you have a steady hand and a good eye, but I used an angle grinder with an aluminum wheel to remove the material in the rims - it worked fine, albeit a bit slowly (I was sneaking up on the I.D.)
I started drilling holes in brake drums & rotors 20 years ago to reduce rotating mass and increase heat dissipation, and have machined drums down while on the vehicle to get the wheels to fit properly.

Shucks, we've turned the front rotors down on the '98 several times w/o removing them - just lift the truck, take off the front wheels and put it in gear while using the grinder... works as well as the lathe I used to run!
