anybody know what reamer i need for a 67-69 camaro balljoint and tie rod end?
are they the same taper as a 70-81 camaro?
trying to adapt something, i'll turn ya all on to it IF it works.

Most ball joints have the same taper......................if you are trying different splindles, it depends if you can adjust the alignment enough to compensate.

"Most ball joints have the same taper"


and that is...what?

[willys36@aol.com]

1 1/2"/ft.

See this.

[tomslik]

seen 'em but it didn't say that the 67-69 camaro balljoint taper is the same as 70-up...
i know they're not the same part #.
anybody know for sure?

[johnsongrass1]

68/69 was a SAE car and 70-79 were as well. 80 and newer used metric spindles.

[tomslik]

ok, so are the ball joint tapers the same from 67-79?

[Wrench Bender 1]

Correct me if I'm wrong but the tapper your looking for is 6 degrees!

[Triaged]

1.5"/ft actually ends up being 7.15deg. People have used 7deg taper (total angel -3.5deg per side) and it has worked fine.

[tomslik]

well, just an update,. did find out that the tapers are the same, now just have to find a reamer cheaper that a 100 friggin' dollars...

I found this doing some diging. I have no idea if it is still good info but you can call and check.

I got mine from Chadwick Reamers 877-492-8249
85020 Taper 1.5"/ft. Range 7/16"-1". Spiral cut, 6 flute. 1/2" shank with hole and handle pin, 01 tool steel treated to Rockwell 60 hardness. $50.40.
85500 Taper 2"/foot. Range 3/8"-1-1/8". $70.88.
I have both and I'm happy with them. These are the best prices I was able to find.

I also found this

I also read and heard in my searching that SOME "bridge" or "car" (railroad) reamers will work but I didn't want to mess with it over a few $$$.

[tomslik]

well, here's an update.
bought both bj reamers and the 1 1/2 is correct for pre 78 spindles and the 2 is for "metric"bj's(78-up)

i AM talking about chevelle spindles,for the record.
both of 'em set me back less than 80 bucks from XKUT..

thanks triaged for the tip!!!

Glad I was able to help. I have been driving my truck with my re-tapered ptiman arm for a while now. I tapered it on the truck with a 1/2" drill and ALOT of cutting fluid (I used some cheep "dark" cutting fluid from Home Depot - nothing special). If you don't get the speed and pressure just right it will chatter, but when you get it right it takes material off very quick and smooth. You will have to give it more pressure to start it but once it starts to cut you can let off and let the tool do the work for you.

I am sure the chattering is partally from the straight flutes and that using the $$$ stock car products one might work better and/or be easier to use...but for enlarging a taper that already exists (rather then tappering a plain hole) I think the much cheeper straight flute tool works well.

[tomslik]

you're probably right about the straight flute thing but no more than i'll probably use it, it'll work fine.
