I bought my Durston some 25yrs ago and its as good as the day i bought it My need was to do production milling so I motorised it. Has been fine.this way. However when making tapered section material one needs to wind in then reverse out. Then move down to the next groove and repeat. So to do this I put the handle back on. Cant do this if its motorised. Since then I accumulated several mills all flat. The last one has a big 3ft 50lb flywheel on the handle shaft. with a 5 to I reduction. rolls 5 by 2.5in dia. Had to get them reground to produce a true straight roll. Last year I had to mint 2500 commemorative plaques for a 40th anniversary . the material supplied was 3in wide by .036in thick.70/30 lead free guilding metal. On calculating the length needed to make this no the client supplied material left me with 500 approx short. Ie enough for 2000, What to do? Cant ask for more, so I motorised this latest mill, set up input guide rails, cut 3ft lengths of material and rolled it down so it was 48in long. Reduction to .027in. Worked just fine. From cutting the sheet in strips(5 off) rolling, guillotining to length, hot drop stamping, pickling, clipping then date stamping, total of 50 in each production day of 6 hrs work. If youve wondered as to the heating to dull cherry red. made a Davy miners lamp principle of controlled neutral non oxidising stainless steel gauze muffle. with hinged top. Can see when its the right temp by colour . Remove with tongs drop stamp thne pickle rince neutralise dry and stack. Hope this is of interest. Ted Dorset UK. You could have spared us the story and just posted the first sentence. But no, you needed to take up bandwidth and take 127 lines for that! -- Abrasha http://www.abrasha.com |

Yes, the first sentance was mostly enough for the exact topic of the thread. But his last sentance was the reason for the rest. And I for one, even if it had less to do with the thread's question at hand, found the description of his recent project of interest. Perhaps others did as well. and it's not as though the group's current activity level is straining anyone's bandwidth capacities... :-) Peter |

For the record the original enquirer asked for ANY suggestions or information. If yoiu dont approve of my posts then you shouldnt read them. If the moderator of this news group thinks I should change the way I post then its up to him to tell me, dont you think? Hand milling is good for small stuff, but when you have to process some 125kgs of material then power milling is the way o go. I tried to hand mill it but it was too much effort. I used a 3hp motor running ar 1440 rpm, with a 3 in pulley and an a section vee belt driving onto the 36in dia flywheel. Hope this helps those who might have to do this one day.Im probably the only one man band production drop stamper that uses all kinds of techniques including those from the jewellery world. |

I think that it's a good idea to have information about these kinds of things. I'd like to hear more, thanks.

I for one would be interested in what you Peter had through your hands that perhaps was unusual, or difficult and you solved the problem in your expert way. Also what Abrasha might be doing as well. If you Peter think that this might be a good idea let us know. Im reluctant to post details of my current project( an unusual one) incase im shouted down again. Ted. |

If you Peter think that this might be a good idea let us know. Im reluctant to post details of my current project( an unusual one) incase im shouted down again. Ted. You weren't shouted down. I believe Abrasha was merely offering us his typically brief and perhaps blunt opinion that your project description wasn't along the topic's original question any more. He's perhaps right to some extent on that, though your explanation makes sense too. Whatever the case, your suggestion is for a different thing, and frankly, it sounds OK to me. I can't promise I'll be adding all that much, unless you want the thrilling details of things like my current worries about health insurance and the slowdown in business. But that's economics, not jewelry, and possibly not appropriate to the group. But if you'd like to keep us informed of your current ideas and projects, I'm all in favor of it. So sure. So long as it's reasonably on topic for the group, send it in. Might be a fun idea. Peter Rowe moderator rec.crafts.jewelry |

In the magical world of this newsgroup called rec.crafts.jewelry on
Fri, 13 Mar 2009 17:16:43 -0700 we were all amazed to see Abrasha write: FC... wrote: I found this one at Rio and it looks like just the Rolling Mill I might Need ! It looks like it might be of better quality than the PEPE unit. I like the fact that it has a much wider 'FLAT" surface too. What do you folks think... ? DRM C130 with Reduction http://www.durston.co.uk/lan-en/prod-m-drm130-en.htm Don't get it! Rolling mills with both the sheet and wire mill on one set of rolls are no good. They are like sofa beds! I hate to admit it, but I agree with Abrasha. Oh God! I feel so dirty! The width of the sheet section is only 80 mm, which means that you only have about 60 to 65 mm of usable width to roll sheet, because it is not possible to use that full width to roll sheet. Get a mill with it;s full width used for sheet or wire. That may mean you need to get two mills or one with the rolls above each other. |
