Hi
It looks as though I will have to design a new boiler for my 1½" Burrell single crank compound engine as the original drawing is just not up to current standards.
So with that in mind I am looking for a drawing of the Allchin 1½" boiler to crib a few design details if anyone has a spare copy that i could beg, buy or borrow for a while. My logic is that if I keep the design as close as possible to the Alchin, it will not frighten the club boiler inspector as much as it would if it was a total unknown.
The other thing I am looking for is a set of four Allchin rear wheel tee rings, they are the same size as I need for the Burrell.
Thanks
Phil
