I have made the Gap piece, but I cannot find which is the front and which the rear !!.
At one end there is a 3/8" overlap, and at the other it is 1/4" .
I need t know, as I cannot proceed with marking out the the Rilling rrig. in that there is 1/8" at front, and 1/4" qat tghe rear face.
Alas I have been in hospital for a while, but am now bacck and active (slowly !!)
I have almost completed the boiler, and will put photos up,when it is done.
A VERY HAPPY CHRISTMAS TO EVERYONE
Malcolm
