Labour was cheap in the day, I could imagine that in order to get the thing in a position like that you just pulled open another can of workers. And every single one of them was probably very strong. It takes a lot of Thursdaynighters to lift a big clump of metal, but most of us have jobs that involve a lot of office work! That doesn't help.

I don't think I say anything new here actually. Good to contemplate how times have changed though... I bet these mine workers never expected micropalaeontologists and photographers and web designers (!) and the likes to scurry around in their workplace some 120 years later...

Almost exactly like that. Although typically the drill would be attached to a horizontal arm which in turn is attached to the vertical (jack) bar. This means that the drill can move in both the horizontal and vertical planes which is pretty essential when drilling a full round.

I am gently acquiring the bits to put a bar and arm set up together so we can rig the thing properly and, if the thing runs, put a few holes in.

These things could be mounted on a heavily weighted tripod for quarry work. If anyone has a copy of "Climax Illustrated" (yes I know) there is a photo of an Imperial rigged in this way.

Thanks Roy, I somehow got the idea that it may have been used above head height and speculated on the possibilities.

Edit: Tamarmoles post clears up the tripod theory.Smile

We were still moving 2 ton motors about on scaff pole rollers in less than 6 feet of height in the late 70s, as you say, get a few more fitters mates on the job.Big Grin

I love the way the lad on the left has sledge at the ready to give it a clout when it jams.

You'd expect the exhaust to blow the candles out as well - not a great place to be in the complete dark with a buggering great air drill bellowing away .....Crying

The tripod set-up is shown, for a Holman drill, on the top of their invoices from the early 20th cent.

when you see it you understand what a leap forward the air leg actually was! the jack bar was easily the weight of the machine itself, we scrapped one of those a few years back at the test mine (was one solid bit of rust by then, left underground too long), took two of us to get it in the skip

The sledgehammer looks like it has a pick hilt fitted to it judging by the width below the head. I guess whatever was readily to hand

Some what Off Topic but...
The Health & Safety at work act only came about in 1974. With organisations only realy realising its implications over the early 1990's. With many still having no idea what their obligations are.

To compare Morlock's 2 tonne shifting experience, the upper manual handling load is around 25kg these days. All subject to RAMS of course.

Yes, bags of cement halved in size overnight - little or no reduction in price though Cursing
Now very OT, sorry.

It's still perfectly possible to move substantially heavy things with several people and the use of rollers, levers etc. We do it quite often.

It's just a matter of (as always) risk assessment.

It's quite expensive these days to break people.......

Re-the underground photo, I wonder if they are drilling some kind of drag or V cut?

Climax project part 5.

15.4.2017

J25GTi and I painting and cleaning bits and bobs. Nothing photo worthy. Hopefully next session we will be fitting the piston and the rifle and ratchet bar assembly.

Before then I need to source some 4mm leather strip to make the piston ring packing.

Climax project part 6.

21.4.2017

The main event of the evening was fitting the piston rings and manufacturing and fitting the leather packing rings. We also reassembled the ratchet assembly.

The contact adhesive we used (some savage German stuff called Klebfest) needs 24 hours to cure so we were unable to fit the piston into the cylinder tonight. Hopefully it should all come together next session.

J25GTi's photos from this evening:

Found this in one of my box files - hope it's both relevant and of interest.
