I'm planning a bubble car build using mini uprights. Either I have to use the original iron suspension arms or I have to make my own steel tube
wishbones. If I make my own, I'll need to cut tapered holes for the ball joints top and bottom.
What is the taper of a mini ball joint.
What alternatives are there other than OE iron arms or custom made steel?
My Alfa 156 has alloy wishbones - maybe adaptable?
This isn't going to be much help... but while trawling the net a few weeks back I came across mini uprights made from ally - they are extensively
used in hillclimb and lightweight specials for racing (I'm told!) so shouldn't be that hard to come by - certainly worth putting some time
into a search to see if they make other parts as well.

I don't think the uprights used by Zcars for their Mini are that dear.?.

Kent Auto Developments produce lots of special goodies for minis, might be worth a try

The steel in Mini bottom arms is weldable --- Mini freaks have been making adjustable bottom arms for 40 odd years without problem.
Are the top arms weldable too?

Mini ball joint taper is a 7 degree included angle.
The ball joint pin can be turned down parallel and a spherical bearing can be used in your suspension arm.

Like this but with a single spherical bearing on the top ball joint, the taper is removed on the tapered pin to resemble a bolt shank and then a standard spherical bearind can be fitted to it. Non of this sort of thing would use a top cast arm
Well all I can say is I've seen it done several times and it seems to work well enough

Found this picture of what they do with metro uprights in this case on a terrapin, they make an adapter which screws into the normal balljoint cups,
this version has no movement in the replacement balljoint all the movement is in the rose joint
But like I said I have seen both ways done to achieve this

I have 4 bushes with a mini taper reamed into them - they were bought for a previous project from the company that make wishbones for the GTM Libra. You can weld them to the end of wishbones. I also have 2 metro front uprights - these have a 'bolt on' type ball joint that could be used on a lower wishbone. I'm open to offers if these are any good to you. I'm away until Saturday 17th but I'll reply then if you are interested!

I thought when they used the spherical bearing option, they cut the ball down to create a pin that the spherical bearing would fit on, rather than the taper?
