I've never seen a shrouded, non-rotating intake valve before.  How the heck would you weld a shroud to a valve without warping it?

Thanks for letting us follow along and learn some new things from you!

Finally getting the Bamford back together after waiting for the crank grinder. I sold mine a few years ago, wish I'd kept it. Also how to keep those banjo fittings from leaking which is a huge problem with the China and India parts. These are called Dowdy washers or Bonded seals depending on where you live. They have a soft seal to take up irregularities and a hard washer to tighten against. Your connection will be leak free. Now 9 Bamfords sitting here, anyone want a job????

I would come and do the job for nothing, just for the opportunity to learn from the master. Sadly the commute from Tasmania might be a bit much.

I will take one on but you probably wont see it ever again. Freight to Oz is dear but Im patient. I think we call them DOwdy washers but in the past I've simply annealed the copper washer and it sealed again.

Dowty washers, but I also just anneal the copper ones.  Have never been an issue.  Dowty's were really designed for hydraulic lines

I have used both copper and Dowty washers in many situations in the past. Of the two I prefer annealed copper because it does not decay like the neoprene O'Ring in a Dowty washer. Many years ago I had to fight a fire in a very large air compressor, a dowty washer had been weeping cooling oil onto the internal electric drive motor. The vertical chimney and cooling matrix was also full of cooling oil. When it caught fire it went up like an atomic bomb. Four engineers managed to control the blaze until the fire fighters arrived. Hundreds of thousands of dollars of damage!
