Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

So you don't have 24" length of board ,you could mount 4 opposing each other...

I did think about this, a 4+4 configuration would give me the smallest footprint, I do think a "straight eight" configuration would "look" neat, but I think your estimate of 24 inch long board is quite accurate. I will dry stack them both ways and decide which I prefure. My last order of 4 engines tryed to deliver today but mailman was scared of my driveway so off to the post office
