I've just recently got myself a very large German Bing steam engine to restore.
Haven't nailed the date down on it exactly yet but its was made some time between 1908 and 1925.
Now a few of the screws / bolts are missing from it and will need to be replaced.
I would prefer not to have to drill out the threads in the castings and retap them with modern metric threads if I can help it.
I've been told that on something like this the threads will be metric but at a different pitch to ISO metric threads.
Does anyone here know if this is true and if so does anyone know where I can buy some screws or at least dies to make new ones?
Thanks
