Reamer Size for Tie Rod Over - Confirmation Please

[joshd1971bronco]

Guys, I did some research on here. I need the reamer to do a tie rod over but was having trouble finding the right size. I found a couple references to a SnapOn part number R121 that is a "1/2 inch to 1 inch" reamer. Found another post about the chevy 1 ton TRE's being an "8 degree reamer".

I went to a local tool shop here and they sell some off brand stuff but they don't list the degree of taper which I know has to be critical to match with the tapered stud on the steering.

So, if I am going to be doing a TRO on a '76 with disc brakes using Wild Horses custom T-style linkage - what size reamer am I supposed to look for (don't want to pay $80+s/h)? What if I go with the BC Broncos tapered stud / heim joint setup? Same size reamer?

One more thing...

Found another reference that mentions a taper of 1.5 inches per foot.

So, there you go....now I'm a little more confused!!!

I thought it was 7 degrees.

BCB or WH.......Vendors are there to help....Use them!

Confirmed.
WH does sell the correct one.


7* or 1.5"/foot taper. or 1/2 to 1
How ever you want to look at it

Snap on reamer

I have the Snap on Reamer. I've used it on 2 Broncos and it still works fine. 1.5* per foot is the one you want.

 

[Dude seriously]

According to the math wizz at Solidworks, 7 degrees works out to be 1.47341473" over 12".

I borrowed a tapered reamer when I drilled mine out and never bothered to check it. With that said, Chuck at BC suggested using the Snap On R121 the last time I spoke with him on the phone.

He's close. 1.4624321208617697733547270307783" actually.

Damn, math is hard.

Hehe...thanks guys. I appreciate the..uh...detailed number crunching. ;D
As an engineer, I can appreciate taking things out to the 24th digit, especially when the work will be performed most likely in a dimly lit garage, after a beer or two, late at night!

You want want one with the spiral flutes. The snap-on reamer is a joke. Been there done that.

This is the one I have, and it cuts like butter. $80
