dummy R-2800 Pratt & Whitney
This is a build thread for the dummy radial we built for our Meister P-47. It started life as a 1/5 scale FTE resin dummy. The cylinders are not bad, but we wanted to add more detail and ad a better looking crank case and reduction housing. We cut the cylinders off and discarded the rest.
Here is the start. We used layers of 1/4" ply for the crank case. The housing was cut from the center of the stock Meister cowl. The backing for the engine is a cowl ring fit to the cowl so it is at the correct depth.

Now various structures were added. The governors, mags, and other structure. Materials used were balsa, foam, aluminum tube. The small white circle will become the Pratt & Whitney emblem later. After this was all in place, I coated it all again with LS to produce fillets and connect all the structure so it looks cast.

OK guys, Here's Ram's big secret....He went out and met with Rick Moranis, found the secret location of the "Honey, I Shrunk The Kids" shrink raygun, stole it, went over to Dayton to the air museum....Now there's a curator scratching his head wondering where their PW R-2800 static display went!
Nice job, Gary!!

Are you getting one of Franks castings (I think this is the one Meister has)? If so, it is a good place to start. I used a thin cutting wheel in my Dremel to clean up in between some of the fins, but overall, it is good. The valve covers lack a lot of detail, but as you can see from the picture of it mounted, you don't see 80% of that anyway. As you know, the top and bottom halves of the cylinders were separate, hence the clamp, and Franks casting gives you the place for this. I considered making small claps from brass, but then opted to just paint them on, and spend time on other parts like the emblem (the part I am most proud of).
I wish I had taken more pictures of the aluminum wire housing under construction. I poured sand in the tube, bent it around a form, drilled holes around it for the spurs, cut one size smaller diameter pieces for them, glued each one in with thick CA, then painted it.
