I'm fairly sure that it is what you would refer to as a sinker.

Thanks.

No, its a stoper. Jackleg pushes the drill upwards. Can be used for all manner of jobs but intended as a stoping drill.
Nice toy though. How much? Got any photos?

It was used for road construction, had it around 20 years, hooked it up to a mates compressor and it works fine. I would imagine it could do with lubricating etc, I'm not au fait with terms you lads are using. hope this pic works

When I was at the Brittania museum in BC a few weeks back they literally had stacks of these on pallets out the back.

Is this similar to the one Tamarmole was restoring - did that ever get finished?

I keep thinking I'd like one of these, not sure what I'd do with it though or where I'd keep it - and Nikki would have a fit and banish me to the sofa for a few weeks....Sad

You must have strong arms, unless you were underhand stoping.
The only ones that I’ve ever seen called stopers are the ones with an axial leg, like the picture on A P Browns website:

But no more from me as I’m getting bored. Wink

I'd call that a sinker. The stopers have an integral airleg in the same plane as the body of the drill, whilst the airleg machines have a seperate air leg.

Alex, the drill I was restoring is much older and is known as a bar an arm machine. It was loted to a steel framework. We never quite finished the rebuild because we lost the workshop /shed we were using. All the bits are carefully stored and work will resume dreckly.

Underground where I worked the one in the OP's photo was used primarily for drilling downwards, ie: in a underhand stope or sometimes for drilling horizontal holes for iron pegs in a very narrow drive or stope, in the first scenario weight, balance and a no fear of falling was needed, I would stand on the handle while the machine man would operate the machine, starting off a hole was down to pushy down muscle power, in the second scenario it was muscle power only and then some.

One with a built in air leg was always called a stoper, used for drilling vertical or near vertical holes in the back of stopes or for drilling holes in a box hole round.

One fitted to a jackleg was used mainly for drilling tunnel rounds, drilling benches in a shrinkage stope and drilling raise rounds....also occasionally used as a sub for a stoper when drilling box hole rounds (machine tied tight back to the jackleg)

Lozz.

You wouldnt be using the one in Bills photo as a stoper ie. drilling rounds in stopes, the main reason being you'd struggle to drill off the horizontal without the air leg, and if you managed it you'd have no support to help guide the holes, spacing wouldn't be worth a damn

We always used them for drilling downwards. Sinking shafts or underhand stope. We used jackleg for drilling tunnels or stoping upwards

Apologies I hadn't actually looked at the photo Blush Just seemed to remember that a 3 was a stoper. Correct, its just a rock drill; an airleg stoping drill would be a nice toy to have though Thumb Up

Ah, thanks Rick, I thought I hadn't seen any more on the restoration but it's easy to miss stuff. I think the ones stacked up at Brittania were more like this one.

I did test the water by showing Nikki the picture of the one for sale and suggesting it might look nice cleaned up and mounted on the wall. No actual words were spoken but the facial expressions weren't promising Crying

So what is the Holman model number for an integral air leg stoping drill? Where the airleg is actually part of the body of the drill and is in line.
Normal rock drill can be fitted with a jackleg for bolting faces or tunnel rounds.

(Silver) 303S was the Stoper with the integral leg, the 303A was for a separate Air leg (jackleg) and the 303H was for manual Hand pushy pushy....so far as I know.

Maybe the Silver 3 followed the same suffix regime?

The 303H was an airleg machine with separate air feeds to the machine and to the leg (I've got one)
