Hi John
There are a number of questions that I would like to raise firstly have you done any research into this loco or just fancied the pic in the Reeves Cat.
Side tank in my opinion for a starter is easier than a sadle tank.
Next the Boiler, Oh boy have you built a boiler before and is the kit going to be already flanged or just sheets of copper if so will they supply the flanging formers. I would reccomend you contact a boiler builder and get one professionally made, CE marked , try western steam and other companies who advertise in ME. A 5" boiler is LARGE and needs a lot of heat constantly while constructing it. It is a seriose no messing about build and you need to get your club boiler inspector to with all the tests. Please ask if you want advice.
Like David I do not know of anyone who is doing off the shelf laser cut frames, about 3 companies comes to mind but there will be a premium for a first of and proving the drawing is accurate. If you go the hsrd way that is a s*** load of metal cutting on a 5" frame.. The Reeves drawings are now very old and have never been updated so lot of errors.
There are many errors in the drawings, look on the ME workshop forum.
