ANDY Posted March 9, 2012 Author Report Share Posted March 9, 2012 really nice work lee, top notch. same cones as me. defo gravo part who is the phantom bottle smasher? Link to comment Share on other sites More sharing options...
Satiusreesadimus Posted March 9, 2012 Report Share Posted March 9, 2012 Just for the record I have not completed any survey and it is not me who had a smashed bottle. I would not be stupid enough to engrave one in the first instance - I see that not content with weakening a vessel with probably 4 bar of pressure inside already we are now putting it in a window where each degree centigrade rise will increase the pressure by probably 2 bar. I shall leave this one to you because it seems common sense is suspended in pursuit of a quick pound. Good luck Gentlemen. Link to comment Share on other sites More sharing options...
StevenB Posted March 9, 2012 Report Share Posted March 9, 2012 Calm down Rob, I'm sure these bottles are not used at the limit of their strength tolerances - and not all of us get the sun shining on our shop windows... \:D/ Link to comment Share on other sites More sharing options...
grahamparker Posted March 9, 2012 Report Share Posted March 9, 2012 I have to agree with Rob and will not be tempting fate trying to engrave one. Link to comment Share on other sites More sharing options...

Oh Please!!!! what a load of piffle I only express my opinion, you can check the facts, take it on board or neglect it. Me well i take in information, do my research and make my own conclusions. Of course that we deal with stress fracture propogation causes and effect everyday in our aviation engineering mode would in your eyes brings nothing to the table - I wonder what qualifications you have but there again I guess a statement "what a load of piffle " only requires one to attend primary school. I will argue that I am correct on this one but it is probably a wate of time debating Griffith;s theory of brittle fracture or youngs modulus with someone that is only capable of contributing such statement . I actually could not care less if you go engrave champagne bottles,, i only joined this discussion as it was obvious that some were not aware of the potential problem - yourself included it seems, and the "give knowledge to a wise man and he will be yet wiser" has never done me any harm. You discount my argument but would not I suppose engrave a calor gas bottle were I to bring it into your shop yet the pressure in that is much less than a champagne bottle and the container is less brittlle. I would back my argument up with research: Have a look at 1:3 here , http://www.cv.titech.ac.jp/~miki-lab/en ... report.pdf if you want a 3rd party opinion "The laboratory demonstrated that the fracture strength of brittle materials is extraordinarily sensitive to flaws introduced at their surface during manufacture and subsequent usage." perhaps that is piffle also ???? If you have qualification or evidence that Griffiths theory is wrong then I assure you every scientific institution in the world is going to pay you to come lecture them and explain. If you have no evidence then perhaps you should refrain from comment as you might just contribute to someone being injured through neglect. Over to you.

derek Posted March 9, 2012 Report Share Posted March 9, 2012 What did you use at t'other end though? would 2 peices of micro with a hole cut out the 1st piece be soft enough to grip it? Link to comment Share on other sites More sharing options...
stevecoco Posted March 9, 2012 Report Share Posted March 9, 2012 Being an ex aircraft engineer (32 years) myself your argument backed up with impeccable references is undoubtedly correct, but the POLL taken shows only 1 person has had a problem ( OK in a H&S environment one is always too much). Based on that assumption people have made there own decisions to engrave the bottles. Facts and statistics can be manipulated in any way shape or form.

Lee Posted March 9, 2012 Report Share Posted March 9, 2012 What did you use at t'other end though? would 2 peices of micro with a hole cut out the 1st piece be soft enough to grip it? why not just invest in the right holders from your engraving machine manufacturers, you have after all invested a large amount of money in the machine in the first place. A few extra dollars to relieve the stress wouldn't go amiss Lee Link to comment Share on other sites More sharing options...

ANDY Posted March 9, 2012 Author Report Share Posted March 9, 2012 it's an odds game with normal glass engraving, eventually something will smash, it's happened to me before and it will happen again. the chances of it happening are slim, but i wont turn glass work away based on the odds. no doubt eventually a bottle will break, i'd guess the odds are higher and it will be messy. but still no reason to avoid doing it if you take the proper precaucions, eg. NOT staring at the bottle in wonderment from 2 inches away and covering vunerable machine areas "just in case" i cant see a problem i've also done my own research on you tube one guy shot a champagne bottle and another smacked it with a golf club, both in super slo mo i might add neither really exploded like i imagined they would, after a small bit of a foamy splash, most of the liquid fell to earth i wonder if the phantom flan flinger and the phantom bottle smasher are one and the same Link to comment Share on other sites More sharing options...
