antispad, glad you liked it. Let me know if you'd like more pictures. The trickiest part (if you could even call it that) is the miter cut on the 4 legs, otherwise everything else is simple straight cuts. I use 3" or 3-1/2" drywall screws all around.

Yes, the Irvine .53 is my latest acquisition and is one nice powerplant. Small complaint about the muffler, though. The extension part doesn't fit very tightly and a lot of oil oozes out of the joint while the engine is running.
