Nice work on the frame. It looks like the drivers may be a challenge. -- Russ

Here's two pics of the wheels and the gears with the painted frame. I will paint out the rust on the wood parts.

Here are two photos of the boiler, unpainted and over 1000 parts.

I don't see putty. I see virtual perfection. -- Russ

    Gordon,

   do you prepare for each part an expanded drawing ( unfolded) to be able to cut the correct shape and mark all rivet positions ? I am impressed by the accuracy of the reinforcement ring of the boiler/ dome connection.

Thanks guys for your comments. For this boiler the only drawing I made was a cross section so I can line up the top, center and bottom parts of the boiler. After the center part has been wrapped with a sheet of styrene I take the rough formed top and bottom cores and fit them to the center part and trace a line to show their location. Extend these lines out the width of the flange and use this for the pattern. Cut these parts out of sheet styrene and add to the center part. The bottom core is made out of wood and is added to the flange sheet that is on the center part. Now add a sheet of styrene to all four sides having them fit up tight to the flange. The top core is made from a section of 1 1/2" ABS pipe with the bottom shaped to fit the center part. Wrap this core with a sheet of styrene that is longer on the bottom.  Tape this sheet to the core and trace and cut to the shape of the core leaving about two scale inches longer than the core on the bottom. Glue the core and wrapping together. Now when shaping and fitting this to the flange sheet you are only shaping the thin sheet of styrene and not the thick core. This now can be glued onto the flange sheet. The core for the center part is a section of 2 1/2" O.D. tubing from Plastruct. I use sand paper wrapped around a same size piece of pipe or tube to do the shaping.

Very impressive Gordon!
Just curious, and couldn't figure it out from the post above.
Do you lay out the rivets on the styrene sheet before wrapping or after?
-Marty

Scratchman

Marty, on the first wrap of the center part I lay out the top line, the bottom line and a line on each side all going from end to end. Working the other way I draw a line at the first and second row of rivets and a line centered on the steam dome. I don"t lay out rivets until all three parts are connected.
