I'm not sure the Astra ball joints will be overly suitable as they are designed for use with a McPherson strut, i.e. they only have to support
lateral loads rather than any weight.

I've got some Astra ball joints which i'm planning to use on Sierra uprights. When pressed in by hand there is a small amount of play at
the thick end of the taper. I'm not sure whether there will still be movement when it's tightened. I'll try it as soon as i get hold
of a nut with a suitable thread. Looks fairly promising though.

Hi, sorry to drag up an old thread here but I was looking for some help with making some of these mushroom inserts.
A friend asked me to make him a couple on a CNC lathe at work and seeing as it’s CNC there is no need to ream the tapered hole as I can bore it out
strait to the correct angle.
He gave me a copy of a drawing which is the same as the second one on this thread, but nether that drawing or the other one on here actually work out
at 7.125 degrees. The first one works out at 9.036 and the second one works out at 8.666, both are quite a bit off...
I was wandering if anyone else had come across this? Should I make it to the drawing and trust they will work, or change the dimensions to get the
7.125 degrees?
Or perhaps does someone have another drawing?
Thanks in advance
Jonathan

Hi Jonathan
No need to appologise for dragging up an old thread - on the contrary, it shows you've taken the time and effort to search the forum.
As far as the taper goes - if you have CNC facilities available, why not get one of the tapers your pal intends to use and measure that?
Regards Mick

I would but the ones he has are far too chewed and corroded to measure accurately, even if they were in good condition the only true way to get close
to 0.001 of a degrees is with a good shadowgraph or CMM, nether or which I have access to at work.
I could probably measure them close enough for what they are doing. But I’m an engineer, I’m not a big fan of “close enough” if I can I generally aim
for “right” and if it ends up close enough then so be it.
He said he would get some new ones but as of yet has not got around to it so I am left waiting.
