This is a good idea, I never thought of drilling holes in beach stones to use for the beads,

Have you looked into ultrasonic drilling? This uses sound waves to drill a hole or even sculpt out entire pieces from precious and semi-precious stones. It's a widely used method here in Japan from drilling precious and semi precious stones. Most of the equipment is either USA or German made. In Germany this technique is widely used for drilling stones and fabricating sculpted gem stones. In the USA it is more widely used for fabricating electronic and nao technology components. Of course, depending on the Mohs rating of hardness of the stones you are using, there are many other options including even HSS (High Speed Steel) . Diamond drills are readily available, and very good quality, relatively inexpensive sintered drills are made in the USA. Also, if used with care ordinary HSS drills can drill some stones. Finally, there is the time tested method of using an abrasive, a copper tube and drilling under water.It's a subject with almost no end of variations. I've done a lot of glass drilling for clocks I've made, and this is generally a much more difficult material to work with than most gen stones.

3d printing and laser cuting

tomash — Thu, 16 Oct 2008 15:30:47 GMT

hi

my name is tom, i live in jersalem israel, end i study design

i specialize in creating two formats with my 3d program (solidworks) which you can use.

the first format you can use (for rapidprototiping) when you want to print a 3d wax object which you can later on use for casting all kinds of metals, glass, epoxy and more

the second one you can use when you want to cut or burn metals, glass and wood using a laser.

for more details i'll be happy to help.

basic tools needed

BeadChicka45 — Sun, 07 Sep 2008 05:19:53 GMT

Hi,

I want to set up an area for soldering, but I need to know what tools you would consider the basics, or ones most needed? I have a table to work on, so no bench is needed. And what is the best place to get them? I don't want it to be too expensive, but I would like decent quality. I also am looking for a torch, but I don't think I want an acetylene and oxygen one. Any advice?

Thank you for any help you can give me :)

Type of drill and bits for beach stones?

seascale — Thu, 19 Jun 2008 13:52:32 GMT

Rookie beach stone drill maker here: help! What drill model and drill press is best for drilling thru small beach stones? And where would you purchase the hardware ? Local hardware store or online supplier? My summer art projects are bursting to go : all the raw materials are collected but I need to invest in the tools now. Thanks for any advice.

Re: Drilling with Flex Shaft

Addie Kidd — Thu, 22 May 2008 14:52:33 GMT

Have you tightened the handpiece enough with the chuck key, or is it loose and your drill bit's spinning in place?

Or, did you possibly buy a reversible flex shaft (intended for lefties so that polishing gunk doesn't fly in their faces), and the drill bit is spining backward?

K~Soul, I envy where you live, being Oakland, CA. If you really aren't comfortable in building this yourself you might consider a class or workshop in basic machine work and you happen to live where there is a very nice Industrial Arts school.

http://www.thecrucible.org/

I've never been here but I've heard great things and they appear to have a really good course catalog as well as studio rental spaces. It's something you really should look into. Another alternative is to check at a Junior college near you or Adult Educational stuff at the local school districts for Machine Tech courses.

Step Drill bits are typically for sheetmetal work and not for thick plates. It's best to stick to regular bits for use on plate material. If you do end up getting a drill press and can't fit the material in a vice there are other clamping arrangements. Most good books on Machine Tool Operations have these setups and the only thing I have seen on the web is fairly inadequate but is listed here:

http://its.fvtc.edu/MachShop1/drillpress/default.htm

If you are going to get yourself a drillpress and do this yourself it's critical to make sure the work (e.g. the plate) is held very securely. Also make sure that if the plate hangs over the edge of the table it does so to the left side of the drill chuck. I stress that because depending on how the piece is on the table if it should start spinning (Drills spin clockwise, so picture that plate if it were placed so it was extended on the right side of the machine, suddenly it would spin TOWARDS the operator, ala ginsu knife to the guts, not pretty). It's the sort of thing that can happen even with experienced users and it can really hurt you if you don't have things set up right.

Information is a great thing, but if you aren't familiar with the basic operations yourself, find someone local who can show you or take a basic class. Saving a little money isn't worth getting yourself hurt one bit. Personally I would see what you might get down at the Crucible, but that's just me.

Good luck and please stay safe,
Robert

You can certainly drill the holes yourself. Since it's mild steel do make sure and use a center punch first in the middle of your hole and depending on the size, you may want to open the hole up in stages, for instance a hold that is 1/2" in diameter you might want to drill out first at 1/8", then 1/4" then the full size. If you know what you are doing a good hand held power drill works wonders, but if you really want to make sure the holes are centered and straight consider buying a small drillpress from Harbor Freight or other vender.

Do make sure you have your work clamped well, preferably in a vice. Use your eye protection and once you have drilled through, be careful of the bit catching on a flared edge. Most libraries will have books on basic maching operations and drilling is a very often used skill so I do recommend you learn about it.

There are a lot of links on drilling, you may want to start with the wikipedia article:

Hope that helps,

Drilling holes in - let's say - tourmaline, beryl, etc. ?

MilliJoolz — Fri, 24 Aug 2007 15:06:55 GMT

Is there a (or perhaps more than one) tool that people like I (designing and selling my own stuff) could use with not too many difficulties? I mean, do you need very may tools together, a lot of strength, etc. to do that? I have found really good sources for gemstones unpolished and undrilled for really good prices. So I I want to look into what it would take to do all the finishing myself. Or am I looking at something that is too work- (and $$$-) consuming?

Back in the old forum there was an excellent thread about drilling sea glass, drilling beach glass, drilling stones, drilling glass, and drilling rocks that will answer most ( if not all) of your questions. It's archived at http://cs.beadandbutton.com/beadingforumarchive/forums/p/24096/238794.aspx#238794

Several people added their comments and ideas. It will add to the information in the AJ tutorial.
