Ray,
It is a bit of a long story, but I will keep it short.
A few years ago, maybe 4 or 5, I sent away to Steamech, an email, asking when the laser cut bits would be back stock. As usual, no reply.
About a year later, out of the blue, I had an email off him stating that he had very limited quantity in stock, so I bought a set, complete with the plans.
Soon after, he went out of stock again, and haven't seen them on sale since.
The quality is absolutely great. Except for dressing off the sprue hangers, they are ready to fit (I would polish them first).
When I first got them, I measured up the con rods, machining joining link and caps, and when I worked it all out, when the links are removed, the big end hole in the the cap and rod would be an almost perfect fit dimension.
Sorry it isn't a better picture. The dull ones are from much thicker plate.
All you can really do is send the email, and hopefully wait until he deems it time to contact you, if ever.
John
