J cylinders

[jaime66]

Anyone know of any spare J cylinders ? 

[BEngo]

I have a proven pattern and core box, as well as a machining drawing.  I have not recently investigated UK foundries nor machining facilities, but I think Bridport Foundry would be my starting point if I wanted to have some made.

 

Have you tried RW Davis, or Seaward for cylinders?

R.W.Davis don't have any. Not many J parts left there now.

 

I'm wondering if there might be enough demand to get a batch cast now? Bridport foundry would certainly be an option, as would Taylor's Foundry in Haverhill (actually their ferrous castings are made in Stoke on Trent).

Certainly worth asking around.  I am not in the Kelvin spares group metaverse, but if someone cares to ask for interest on there, I will beat the bushes with my own contacts.  I am quite happy to bring the pattern to the party.

 

Last time I had any made the minimum quantity was 20, but that was in BG.    I still have a good selection of the taps for the head studs!  9/16" BSF is not a recognised thread in Sofia!

 

I should also say that the produced item has a boss where the stay bar fastens, rather than a depression, so this has to be machined off cylinders for No 2, 3, or 4 position and drilled and tapped to suit the stay bar fastener if fitted to No 1 position. Boss removal can be accomplished with an angel grinder if needed.

Do you often grind angels?

Sounds weirdly erotic to me!

Only when I need them to get  voles out of a cauliflower. 

 

More seriously an angel grinder is a heavenly bit of kit. Boss removal with one has potential akin to a chainsaw massacre, if I had a boss these days that is.
