I just sit it in a small Tupperware bowl of water and drill through 1/2 way, flip and drill thru the other side. Only 1 time I ran into an issue and that piece I determined had a piece of metal in it.
I melted titanium in that one just to foil you. HAHAHA I think you did |

Re drilling holes in rocks/glass:
When drilling and about half-way through, I hold a piece of wood/cardboard behind the glass/rock. Besides insuring that my drill won't go through the plastic sandwich box I use, it also absorbs some of the pressure of the drill going through the glass. Helps to avoid blowouts on the backside. So far, so good.

Have only drilled rocks. The rocks are held on a small flat piece of wood in a plastic pan with enough water to keep the top of the rock covered. No blowouts yet but glass would seem to be more susceptible.

No blowouts yet but glass would seem to be more susceptible. I have drilled both Henry and thin glass say 4mm and thinner is vulnerable to breaking fairly easy. Above that it is quite durable. Worst situation is when drilling a potato chip shape where there is not a flat back for spreading the pressure of the down force of the press. Requires less pressure than agate. |

I have never tried drilling glass, but I have heard that if you put a blob of modeling clay on the bottom of your tray and put the glass cab in it, it helps prevent breakage and blow outs.
If anyone tries it, let me know if it works!

If anyone tries it, let me know if it works! No way Robin. That's the answer. Been trying to figure out a -malleable- footing for curved thin glass pieces. Clay is the one ! That would do it. Might be a bit messy but most lapidary is if you have any inkling of production. Lol, remember Silly Putty ? Wonder if it is water resistant ? Available ? Or some type of polymer putty...I'm on it. Thanks, little stuff like this makes worlds spin. Silly Putty was a remarkable achievement in materials to this day. It or something like it may be the trick. Link to all kinds of clays but many are for curing to a hard object: makingsociety.com/2014/03/modelling-clay-moldable-plastic-for-prototyping/I think Silly Putty is your best bet - "If Silly Putty is submerged in warm or hot water, it will become softer and thus "melt" much faster. It also becomes harder to remove small amounts of it from surfaces. After a long period of time, it will return to its original viscosity.[6] en.wikipedia.org/wiki/Silly_Putty Owned by Crayola. I'm going to purchase Silly Putty lol. 3 eggs on Ebay for $11.95, oh boy and can't wait.  |

HankRocks fantastic5 MsAli hummingbirdstones fernwood PatFound some heavy pinch bails, .925, ~$2 each, best and heaviest so far for BO HO and heavier pendants. But for $2 they are 1/2 the cost of Fire Mountain 12mm .925 pinch bails and FM's is no where near as robust. Quit a spoonful of silver fantastic5, thanks for the referral. Impressed with art beads.com 's silver pricing and quality. Will be trying more Artbead findings(pinch bails).  I melt lots of giant pendants "Big Mouth"

I remember swiping the Sunday comics from the newspaper because they were in color and pressing the Silly Putty on them with my sisters. Then we'd stretch the image and distort it into all kinds of weird shapes. Great fun way back then.

I've been looking at those diamond coated discs on-line for awhile, same web site as that link posted here...........Since you've ordered a few of the 60 grit "Joiner" type, curious how well they have held up.....?........would they handle a 3450 rpm beating to shape rough jasper/agate (water applied) application for rough tumble prep......?
I have backing plates, so the cost of the discs at $10.00 (free shipping) a piece seems economical if they will last through a few 10lb sessions of 1" to 3" stones....?
How long did the order take to arrive....?
Thanks..... |

Just a thought -- Silly Putty may be too soft to support your cab for drilling. If it is, go to Walmart and grab some Crayola classic modeling clay (the stuff you played with in art class in grammar school). It doesn't dry out and is reusable. Also has a stiffer consistency. From what I remember, you kneaded it until it softened up a bit and then made whatever your deranged little imagination came up with out of it. I don't think it would be messy at all on a drilling application.

Thanks..... These are OK for glass, only electroplated. And better for less than 1000RPM. Would last me about 10 minutes grinding agate tumbles. If you want a cheap machine to grind agates for tumbling you need to get a 7X1/4 inch Advanta SINTERED tuck blade and mount it in a 3450 RPM cheapo tile saw as in the flickr link. I have tried stacked saw blades at 1725 RPM(super grinder) and they are a joke compared to this tile saw rock eater with $20 Advanta tuck blade and $99 tile saw. It is the 3450 RPM that does the trick for grinding agates. And the 30 grit sintered diamonds in the Advanta. MUST USE WATER, see my garden hose. Not all tile saw slots will allow the 1/4 inch wide blade. Blade on Ebay. Shipping time ?? el if i know. www.flickr.com/photos/67205364@N06/sets/72157683648790962 |

I don't think it would be messy at all on a drilling application. Crayola owns both those products Robin. I'll give the silly putty a try, it does get harder when cold, so my well water will chill it. Will see. I seen the Crayola classic mentioned, it would be my other choice. So you guys used to distort the little cartoon characters ? No shame. Silly Putty is some space age stuff, it defies scientists to this day. The ole WW2 scientists out did themselves on that one. PM me your address. |
