rear spindle (vfr mod) question???

[jaysun0ne]

hay guys

i went last night to finish the vfr rear wheel mod to my spindle.
and found out that the steel is to hard for a typical bit or hhs endmill to cut
and i would need a 12mm solid carbide endmill to do the job my self. well that bit cost $50!
then i thought 47 for 4 lugs and 4 bolts then 50 for the bit i will have almost 100 in this spindle i could buy another one (already modded if im lucky) for about that.

and i do understand there are many ways to get a vfr rim on a hawk, this is the most common and i figured this would be the safest way to do it.

has anyone ever completed this mod (using the vfr lug bolts going into enlarged drive pin bolts) on there own. if you did how did you go about boring the holes out???

and for those that paid how much did the shop charge you for this work???

im will be finished polishing my rim this weekend and wanted to put the rear end together and take some pics need to figure out the cheap way to finish the job.

polished parts so far:
swing arm
cush drive cover
vfr rim
rear brake bracket
ally chain cover

parts i got and still need work:
cbr 1000 forks
frame
cbr900 rear shock hawk spring (may get a rattle can flat black paint job with a chromed spring)

pics to come...


had the crazy thought of chroming a tank with all this polished aluminum but i think that would be to much...

lol, yea a chrome tank would be a bit over the top.. lol



as far as drilling it out and having the center turned down, a FRIENDLY machine shop could be as low as $15...

ive done things like this before, but i also had a friend who worked at a machine shop.. ever since he moved, im even worse off then you are now.. you think its bad with this one project.. try being used to having access to the machines and in the middle of 15 different projects, losing access...

I work at a machine shop and i can do the mod for you with the studs installed and lug nuts for 40 shipped back to you.....your responsible for shipping to me......i think that is pretty fair considering lugs and studs are 20 bones...and that spindle aint light to ship...

I did mine in my garage, with a 12mm cobalt bit, a carbide countersink, and a drill press for the holes, an angle grinder with a cut off disc, and a flap disc.

Worked great.

If you need specifics, let me know.

found the bit for $32 at mc master carr

thanks for the offer tj

if it all goes well i should have the rim mounted by next weekend
i mean i got everything already just need this endmill and then i can finish it. the flange is turned down, got the bolts to press in, and have removed the drive pins. just open up the holes and press them in and its done.

so i guess im seeing this one through to the end

dammmm it

for everyone that has done this before. would some one explain how they opened up the holes on the spindle for the lug bolts. cobalt end mill just didnt seam to work that well. any input will help thanks

how did you use the countersink?
was the cobalt bit used just for a finish cut?

[ovlovder]

I used a cobalt drill bit, 12mm, not an end mill, very slowly with plenty-o cutting fluid.

If I remember, I was very frustrated at first, and thought it was hopeless. I hit it with the countersink lightly to get a better start.

I cant remember what speed I was running the press at but it was slow.

I should really stress patience when starting the holes, triple check you are centered, and if you push to hard you will burn your bit. The spindle is just case hardened, so, when you get through the outer hardened portion you will mow through to the other outer portion, where you want to slow again.

Here is a photo of the finished product.

ok i will try that thanks let you know how it goes
