Tight trunions.
I have a set of front suspension legs from another car which are complete with trunions. they turn very smothly with no binding or slop in any direction. Strangely though, the threads on the legs appear quite worn - that is they resemble a regular two faced screw thread rather than the happy flat-top threads you see on new legs.
I have heard of re-cutting legs to give them a new lease of life. Are these matched to trunions with tighter threads? Could that be waht I have here?

Older and more confused than I could ever imagine possible.

There was a set (left and right hand thread) of 15 thou undersize dies (or is that dice?) on ebay a few months ago, marked with correct BMC part number, the seller advised they were Draper. I nearly bid for them, no one else did. The reason I didn't was because after checking with some suppliers it would appear that the undersize trunnions aren't available.

I thought that the recon king pins had metal applied to the threads and then recut, to give the correct thread. This would alow for standard trunnions to be used, of the shelf. If the king pin thread was only recut, we would have to find trunnions that match the recut king pin. This is not the case. Those recon king pins wear out quickly. the applied metal is not very wear resistant.

The recon, resprayed swivel pins are okay if you cover low milage in a standard car. I would not suggest that these are used for uprated cars as they do not last . The trunnions available now are standard spec suitable for new MOWOG swivel pins. Not sure if anyone offers a cutting service with oversized trunnions. Don't be tempted to fit new trunnions to a leg with worn threads.

In my experience the one's with MOWOG on, are a good product. I'm sure that the tooling is the original equipment, and I'd hope that the steel used for casting would be of suitable quality.
We have run a 1.8K powered minor for around 10,000 miles, some at very high speed on some of the countries most demanding circuits with no detriment to the swivel pins, one showing as to just how good a design these units are and two that the parts are manufactured well enough from durable material.
