Anybody near twin cities considering building a frame? I have one for you for $50. It is standard size glued together. Nearly standard with a little higher beam offset. Message me for additional details.
That frame is now repurposed.
I have a different frame in the Twin cities I’ll give for free if you pick up. It is a bolted version and is slightly smaller than 4x8, but could be adapted to 4x8. I don’t have the long bolts for the beam, but they can be purchased nearby. Send me a direct message if interested.
