Bloody Hell Roger, that is not good. I put a good sized ding in the kitchen ceiling once whilst trying to lever the valve springs back in place on a 16H Norton, needless to say I have the right piece of equipment these days.

Zeroveez. It is all 6082 T6 and 316+ stainless, this one was for a mate who needed some gauging for his F/TR rifle and a spare dial gauge. These days the design has been changed slightly and they are shinier than shiny things which has become a bit of a trade mark for the things I build, every item is hand finished at the polishing bench. This started off as a hobby as the parts I wanted were just too expensive, these days I make as much for myself as possible and yes I put O rings under some of my dies :goodjob:


zeroveez wrote:"They are nice" Yes, I'm very tempted to copy them. The trouble is that I bought my reloading gear in 1996, or so, in a state of ignorance and deprivation, (no lathe or milling machine). Over the years one reads, see's, and learns, (the rubber washers to allow re-sizing dies to "wobble and self centre") for instance, source Precision Shooting Reloading Guide, copyright Precision Shooting Inc., 1995. You buy things that you learn, later, that you might have made better yourself.

Glad to hear you're ok. I think ENS's pipe-drilling still leads the running for the FB(UK) Darwin Award though. :wales:

..
I rock!!!

You should see the close up of the pipe!!! Will load up the pic of pipe and wall!

Cant say what language my wife used to describe me whilst I was getting soaked!! :o
Never knew words like that myself! :G

"I put a good sized ding in the kitchen ceiling" Well now, never mind a ding, there is an actual hole in my garage ceiling. I was making a stuck case extractor, ( M6 hex head bolt soldered into a cut off 308m case; m6 screws into threaded hole in stuck case, case head fits into shell holder, operate press, and bingo, out comes stuck case). Except that when soldering, using a blowtorch and copious amounts of solder, I had failed to notice that the case carried a live primer. Case head was being held in vice, pointing upwards, loud bang, hole in ceiling! M6 bolt is up there somewhere.

Pah, that's nuffink, ooman. A few moons ago back at the Badgercademy of Science and Technology, we were conducting a powder metallurgy experiment with a very powerful hydraulic press. Metal powder was carefully weighed and poured into a tungsten carbide die sheathed in a high tensile steel retaining sleeve, the die placed on the hydraulic ram and the 'on' button pressed. The finger on the dial slowly rotated, clocking up the applied pressure. There then followed a discussion...

Me: "That's almost there, 12,000 psi applied"

Assistant: "No, you're reading the wrong scale. That's only 1,200 psi"

Me: "No, the inner scale is thousands, the outer is hundreds..."

The debate continued in this fashion for some time until I began to get a tiny bit nervous and thought it best to try and seek clarification from a grown up. As I left the room there was a loud

BANG !!!

and everything went dark.



After what seemed like an eternity the darkness faded and it became apparent that the darkness was in fact an eclipse caused by the dispersion of the metal powder throughout the room.

The die?

Well, one half was recovered from the street outside, having passed through three walls to get there. Fortunately it went through the lecture room next door to the lab at head height: fortunate because the students therein were all sitting down.

I believe the second half was never found. There was a hole in the opposite wall where it went out and boresighting through it and the smashed plate glass window beyond gave an indication of the azimuth and trajectory of the die, but not the range...

Heh! I do remember walking into a lecture in the engineering block one morning and spotting a larger than mouse sized hole low down in one wall, apparently the student welders had managed to kick a bottle over next door...

Lee lock rings, one of their better products. :good:
