When I started to build my Horwich Crab I had the opportunity to buy a part finished tender at the right price. It wasn't quite the correct tender for the crab but for me it was near enough, now that I've got the part built engine running on air I thought I'd better finish off this tender. Having a good look at it I realised that it just would,t be quite a suitable tender for the crab (wrong wheel size). To cut my loses I decided to convert it into a water/coal wagon from my Simplex Tank engine, as it would be good practice making a water tank.
This is the finished wagon
It took me a good 1/2 dozen tries to get the tank water tight but I got there in the end.
