The ideal thing would be for those wheels to be small bicycle rims/tires, 10-12 inch but this is only temporary while I finish the tunnel.
More ideally is to have multiples of some things and keep them where they're used. I decided I need another multimeter so I have one in the house and one in the shed. I already have a tire plug kit for each vehicle.
We'll get there. :)
Bicycle tires would definitely roll over rough ground - good idea!
I went back out to the shop around 9:30 last night & worked on the raised beds until 12:15. The 4 long sides (6’) of both beds are finished. I ran out of screws so I’ll be making a trip to the store this morning - the short sides may get done today or tonight. I will need to assemble them very close to where they’ll be sited because they’re heavy when put together.
