I love doing engines!  I wish there were more large scale engine kits.  I recently built the Williams Bros. 1:8 Pratt Whitney Wasp.  Wish they would re-issue the Wright.  This was my second Wasp, have not built the Wright before.

I don't mind scratch building an engine, but it is hard to find decent scale drawings of engines :-(  I do have some old Wylam books with a couple of aircraft engines, and built Hispano from those plans.  Also found some plans for the Offie racing engines, both the 110 (midget) engine and the 270 ci Indy engine is in progress.

That engine looks great, Graham.  I personally find acrylic hard to work with.  I generally use wood on the larger parts, brass or aluminum on smaller parts.

Sure wish WB or someone else would do the R-2800 in large scale!  That was a fantastic engine, and a great looking one too.

Hi Graham;

      I am glad to see you like to work in sheet Acrylic.  I like it too. I do my speed - boat models with entire engines and hardware in Acrylic. Why? Well , I love how well it machines. 

  When I built the " Log Loader " for the court case, in Ken and Barbie scale, all the controls , the cab seat, the Boom Sections and joints as well as the Diesel Engine were done in acrylic.

     When I do large freighters for R.C. they are entirely built of Acrylic Sheet . Why? watertight compartments that are really watertight ! Plus, no warpage as they age and get used. Most can even be run in Real world weather! No water in the Bilges !

   The photos of your engine sure take me back,Thank You !

Great job on the engine, Graham.  The first diesel I worked on was a 3-71 from an Allis Chalmers grader.  Put it all together, then figured out the blower was on the  wrong side.  Had to take all apart and put it together again!  Since then I've done work on the inline 53 and 71 series engines, the 6V, 8V, and 12V-71's, and 6V and 8V-92's including T versions.  Not sure if I ever worked on a 110 version, don't remember.  Your engine looks very accurate but I'll bet your hands didn't get black like mine used to.  The two stroke system really knew how to put carbon in the oil.

Well Hello;

    Boy, you sure hit that on the head. My 6-71s were probably cleaner than some, but certainly dirtier than others. Plus they were noisier than a freight train in a tunnel! Thank Goodness they were all wet exhausts.
