Are the large sized screw in core plugs found on the early blocks available anywhere?
I could make some but if they're a standard size it would save some hard work.

Thanks

My new to me "special" ( Cambridge finned head, 2x SU H? carbs) came with NGK B6HS plugs. Looking at the old forum people were using NGK BP5ES plugs successfully. As I think a couple of my plugs were dodgy I bought 4 new BP5ES (less than £6 delivered for the 4) which arrived today. The reach is about 20mm compared to the current ones about. 13mm. Are these new plugs going to be ok do you think?

   

Has anybody experience of fitting the Bowdenex conversion for front brake cables?

I dismantled everything many years ago and now trying to put it back together again.

The king pins are done, brakes back together with new linings, new bearings and all back together.

Now I come to re-fit the Bowdenex cables. At the backplate is a threaded hole through towards the brake shoes, and on the cable is an end support for the outer cable. This is threaded and screws into the hole in the backplate. To screw this in means revolving the whole cable assembly!!!!!!!!!   Is this really how it's done???

And then, should there be a nut on the other side of the backplate? If so, how do I gain access to put this nut on? Surely I don't have to dismantle the bearings/hub/brake shoes again just to put a nut on the end.

Dave Dye has a couple of my oil pumps for over-boring and renovation. He's also got pretty much all of the vanes I have that aren't inside engines and they're not too good as is often the case. However, the best two have caused us both to be a bit puzzled in that one is 10 thou too long, the other 8 thou meaning that when a pump is assembled using these vanes the base doesn't fit flush with the pump body. In all other dimensions, both are exactly as they should be. Neither of us has ever seen over length vanes before. Any ideas as to why they should be over long?

New vanes don't appear to be available. If anybody's got a couple of good sets spare, I'd be grateful to buy them.

Just found the forum again after messing about on a fishing forum for years. Did a rewire and brake update on the Special last winter. Made the rear brake shoes 'floating.' A great improvement.
It's nice being called a 'Junior Member' in my 80th year.

I have a 3 bearing pressure fed engine to sell , it came with my nippy many years ago .
The engine is stripped down , I had the crankshaft crack tested and it was fine .
aluminium sports sump with the 9 E cast into it , tulip valves but 3 vales are missing in the Block , Dante aluminium sports head , sports canshaft.
Crankcase is un drilled where the oil jets normally go .
All the bits seem to be there apart from 3 valves.
White metal looks good in the con rods and crank looks fine .
con rods are for floating pins .
Strange that they used white metal in these engines, i thought 3 bearings would have had shells.
I have kept the nippy carb , manafold and head as I am using them on my nippy.
I am looking for offers over £3000.00 for this very rare engine that must be a late nippy or speedy engine.

Here are a couple of pictures for Charles Ping relating to his post on the old forum, hope they are of interest 

   
   

Now that we're up and running here (well done chaps), I can post some pics of a ghastly spacial I saw in Puy Notre-Dame. The idea may have been sound but the execution looked as if it had been done in a badly-fitting home-made bender with wooden jaws...or perhaps over the edge of the kitchen table
If he took a sound body off to do this he deserves a horse-whipping!
