what rant?
If I post a
rant, you will know it...
joking apart, there are a lot of well-meaning amateurs on a forum like this, and a rather smaller number of experienced miners of various descriptions and trades. Attitudes do tend to vary rather, and what is regarded a a 'bit of a laff' among the latter does sometimes fall a bit flat with the former.
likewise, there are some things done with all good intention by enthusiasts which make the professionally experienced cringe, but they generally take it in the spirit it's intended. Scaffold pole supports are, in my experience, highly esteemed for digs but not much in favour with HMIM. I certainly wouldn't go to HMIM with the sort of thing you can read on here about digging that tunnel, or a certain well-known members' solo activities in that sphere...
seeing as you cart an eimco, compressor, Hudson tub and track about, I wouldn't have thought three or four arch setts around 2.5m high x 3m span would be an issue. They wouldn't need to be full 'underground' spec, just enough to give the idea. Lay them down, bolt them up and drag them up with the eimco, easy. Tie-bolts to fix 'em at - say - 1m centres, and you have a free-standing structure; tie sills under the track for stability. Maybe a light cladding ( say 6x2 ) overhead to give the impression of spiling boards, bob's your uncle.
