G'day from South Australia.
I just found this site while chasing information on a Bolton vertical steam engine I bought as castings some years ago but due to work ect was unable to do much. No ill health has me retired earlier than expected so I decided to get back to my hobby to help pass time. I dig out the casting and the bits that I had done and then found I can't find the plan sheet hence the search on the www. Found this site and decided to join as there seems to be a shortage of this type of site in Australia.
Cheers
Pete

Hi PD's....& welcome Pete...you have a fellow OZ Adelaide PD member...Martin Blanchard   just up Fullerton Road a bit.... south of the City....

With respect to the Bolton vertical steam engine ...spend some time researching our PD files [in Live Steam] & you will find an excellent set of postings by our UK member "bogstandard"

This could be at least a starting point for you..............Derek
