Hi Spyder
Thanks for that cheery thought! In fairness that is the 5th so only 11 more....oh plus the outer ones +4 ....and the steering arms +4....and the
pushrods.....+8 - Rod ends and enough of this fussiness perhaps??
I will take a picture of the fixture used on the 4 jaw chuck to bore and chamfer the housing - that is the slow bit.

Looks really nicely made. I'd be interested in any machining pics too, I like a dabble on the lathe

Its a weld in end for a wishbone tube. The "hole in the head" is for a spherical bearing to be pushed in and staked making - in effect - a
rod end. The advantage is (1) it is a bit lighter and (2) that there are no threaded parts in shear. The disadvantages are that the wishbone itself is
non adjustable (no issue for me as my brackets and uprights are shim adjustable).
This is the MkII version MkI suffered from distortion when machining the hole. The hole needs to be +/- 0.0005 which is in the limit of my abilities
to say the least.
I have a medium sized CNC lathe bought from ebay for the grand sum of £750 virtually unused from some closed down college or other. I promptly blew up
all of the 1980s electronics in a spectacular disaster and have rebuilt the electronics to run with Mach3 and a pc. It is a little underpowered at the
moment but great for jobs like this.
I will post a series of pictures when I do the next 15.....
If anybody out there knows how to avoid stringy swarf all help gratefully received.

Just had a gander through you're photo archive...that's a rather tidy build going on there, the rest of the wishbones assembly looks very
well done.

just saw your archive. I do hope you have a air-riveter. Nice work.

Hmmm about 6000 rivets and counting - They are all self locking double action rivets (dear old ebay) so needed a special riveter (more ebay) It weighs
about 5kg. Rather wish I had used tubing like most sensible folk.
Taking a day off this week so maybe one more this week....I will take a few pictures as the archive is a bit dated.
