I have a Petter A Stationary engine and need to make some nuts and studs to replace missing ones that keeps the cylinder head on. Other than the right hexagon bar I need to drill out the hole through squarely, then tap it to the right thread and with round bar I need to make a male fitting.
 
I guess I will need a tap and die set, sharp drills and a level bench drill?
 
I expect Mild steel rather than cast iron was used.

If you have a lathe available that will make the job a lot easier, the faces of the hex bar can be machined flat & true, a chamfer added to one face and the hole drilled true.
 
Depending on the thread size they could be screwcut on the lateh but suitable taps and a die will suffice, a tailstock die holder will be handy as well.
 
You can by whitworth nuts assumeing thats what the thread is.

It's worth looking in Yellow pages to see if you've got a decent engineers suppliers near you. In the last 6 months I've bought 3/4 in. Whitworth nuts over the counter for little money, about 10p each I think, and I bought the number I wanted. No pressure to buy a box full. They even seemed amused that I was surprised that they stocked them, said it was a standard stock line that they kept, and this wasn't some old fashioned iron mongers but a modern tool and sundries distributors selling to industry.

Hi, its no surprise that engineer suppliers have Whitworth nuts/bolts, or would be able to source them, especially if they are serving industry. Many of the machinery in Britain is older than most of us, and used Whitworth or BSF threads, which are integral to the machines, and so cannot be converted to metric easily, you just can't scrap production plant for the want of the old British standard threads.
 
Whitworth and BSF may no longer be standard stock items for many suppliers, but they are still available.
 
Regards Nick.

In addition to C.Jacobs posting, if you visit his fastening shop, they can reccomend a local engineering workshop who will saw the head off High Tensile bolts and thread them to order - ie: make studs.

Hi Colin, have you got an old nut from the engine? If so see if you can find someone who has some old style whitworth gear and see if you can match it, if you have to make new ones, make them look a little bit used, they may need a bit of rust pitting, or a corner spanner burred(don't go over board), but just enough that no one knows which ones are new. I'v made new nuts and studs for a number of engines, Blackstone, Ruston Hornsby, Lanz Bulldog and a number of others, and I try to make them the same condition as the existing parts. New parts on old engines should look as if they are origional, and been there since new. Ian S C
