(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?

Lozz.

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

The 303's I used didn't have a separate air feed to the jackleg, the "handle" was unsupported at the operators side, on the operators end of the handle was a twist valve that governed the air feed to the leg and on the end of that was a small push button that retracted the leg, this type can be seen in this video:

I've also got a photo which I believe was taken approx. 47 years ago down South Crofty showing what might be a Silver 3 all rigged up and ready to go.....but I've forgotten how to upload photo's to this site....anyone help??

Cheers for that Sinker...hopefully photo link will display.

Taken approx. 47 years ago, believed to have been taken by me (the miner in the photo owned the camera and I was working with him at that time up in that stope and I remember him asking me to take a couple of photo's)....The stope was a shrinkage stope on the 310 fathom level, from memory somewhere on number 3 lode Robinsons side.

This might be a Silver 3 drill.....long time ago so can't remember exactly but I do remember that some of the miners had Silver 3 drills on a jackleg.

That section of lode was also worked as underhand stopes from the same level, I later worked in one of those at that location, there was another one next to it I remember Raymond Thomas working it and I think a young Robin Boon.....Year approx. 1972/'73..ish.

No worries, the link works fine. Great photo by the way.

That drill is what I thought a Silver 3 was, when mounted on an airleg. It might not be a 'stoping drill' but you could work an overhand or shrinkage stope with that :thumbup:

I have a printout of a pdf file copy of the Holman's book somewhere but since we moved house I can't find the ******. That would explain the different models properly :thumbup:

All the shrinkage stopes I work in down that mine used jackleg machines, as you can see from the photo, drilling would be dead ahead and more or less horizontal, the drill is shown at an angle just for the photo, the steel is a 2ft starter, the lode was quite steep there, hanging wall on the right.

The only time I used a stoper was when drilling box holes and for drilling the odd eye peg hole in the back of a drive.

Here's the other photo from that stope:

EDIT: Here's where I got the Silver 303 A, H and S refs from:

It would seem the Silver 3 was the 1st/prototype in that line of machines, the 303's I've used all had the 'kick up' spring drill steel retainer (see Bills photo), there was a 900 which was a more heavy duty beast too

In the unlikely event that anyone wants more info on the Silver 3, here’s an advert from 1959. Although it is for Holbits, the red photo shows a Silver 3.

The early legs attached by means of clamps onto the side rods. Apologies that the image is rotated, the miner isn’t drilling vertical holes (for which a stoper would be better suited :lol:). CBA muscle currently playing up. Later on you could get a thing with a lug on it that replaced the same “unlugged” part immediately in front of the cylinder block. The hinged bit on the top of the leg then bolted into the lug. These were less likely to rattle loose. I appreciate that we are now in niche info territory and I doubt that I will ever need it again.
