Neal: Yep single story and that’s more or less what I’m doing. This garage was owner built and built from whatever he could find or “acquire”. The starting point was a small single bay he added a wing / lean-to off each side and raised the roof. So much work for saving so little. Most of the lumber is Amish rough cut hemlock that’s as hard as nails and for collar ties he used rail road crossing gates. I don’t know how he came by them and I hope the RR never wants them back. I better paint them as they are white and black now with RR Crossing lettered across. I had a boat load of snow on it this winter and it did ok so I’m assuming its mostly ok and keeping it just adding a brace here and there and a lot of screws because I’m no longer into driving 8” spikes like he did.
Wuzzy: You might be on to something and your math seems correct. I just designed a test machine at work to test the interference fit on locomotive wheels. It twists the axle with a million foot pounds against an immovable wheel. If I had a 1,000,000 foot long handle all it would take is one pound of force.
