How to cut aluminum hard drive platters?

After determining that a hard drive platter is aluminum (I don't want to try to cut the glass ones), how could I cut it neatly?  I'd like to cut out neat rectangles for a small kaleidoscope.  I tried a hacksaw, but it was a messy cut, and I expect it bent the optical surface a bit.  I tried a rotary tool with cut-off discs, but the aluminum chewed up the discs really fast--I could see the discs shrinking before my eyes into tiny circles.

Laser Cutting Digitally Printed Images?

Is it possible to laser cut full color, digitally printed images from fabric? For example, a full color image of a butterfly? Say, if I printed a series of butterflies onto white fabric and then want to have each butterfly laser cut individually from the fabric, is that possible? Can the laser be set up to cut on the outline of the butterfly and leave the colors in tact? Or is my only option to do digital printing after laser cutting the basic shape? Finally, is there anyone willing to help with a prototype that would use the described technique?

Cutting Tin - Candy & Mint Containers

Greetings all,   I have an interest in cutting patterns in the smooth tops of tin candy & mint containers but am a complete noob to this sort of fabricating, would appreciate any helpful offboard links or posted Instructables here. What I'm wanting to achieve is a 'finished' item that looks plasma-cut but since the item itself is quite fragile as well as small in general size I have no clue other than the very time-consuming process of 'routing' out such with a mini-Dremel.     Fairly tight budget here too so a dedicated C-N-C setup is a bit unlikely but no impossible. Thanks in advance !

Cutting a square hole? Answered

This is a really basic question—I have managed to get to 66 years old and still be a complete handyman novice, I have tried but my best efforts are lamentable. I think it is because I have never had anyone to show me handy things and have never asked anyone so turning over a new leaf I am determined to start making a few things instead of spending a fortune buying them and paying people to do things for me. My first project is to make a simple slide carrier and I have bodged one up in cardboard but it really needs to be in something stronger so it is rigid, metal would be ideal but very stiff board would also do if I can not cut the metal. I do have a thin sheet of aluminium, (from the casing of an old laptop) that I would like to use buy am frightened of messing up & worse injuting myself! I now realize that I have no idea how to cut a square hole in a piece of metal or, for that matter, what tools I need to cut aluminium in the first place! My overiding consideration is to be safe so I don't want to try, (what to me is a daunting task but probably to you guys the simplest of things) not knowing what I am doing. So can someone please help me out and tell me what tools I need and how to go about cutting a square hole in a piece of metal? Rest assured I will not do it if I do not think I can safely. Thanks.

Tips on cutting 1"x1" squares out of a thin sheet of pressed wood

Hi everyone, I don't know if I'm posting in the right place, but I figured I'd try anyways. So I'm working on a project, but I have little experience with woodworking tools and methods. I found some nice scrap sheets of pressed wood that are about 1/8" thick that would be perfect for an idea I had to make some tiles for a game. I need to cut these sheets into 1"x1" inch squares and the squareness is important for the pieces to fit together in the long run. From what I've seen "Rail Saws" would be appropriate for something like this, but it's such a small project that I don't think spending that much money on renting one would make much sense. I also considered making my own tool using some kind of sliding mechanism using raisl and an xacto knife since the wood is so thin, but I figured I'd ask here before! I have access to a circular saw and a jigsaw and so was thinking maybe some kind of rail system using them would be appropriate as well, but I'm not quite sure as to how to go about doing it. I appreciate any help! Thanks!

But I can't seem to find a place that can do that kind of cutting.

Laser cutting a spring - choice of material? Answered

I have a scheme that requires a flat, non-conducting spring. Acrylic it too brittle for my needs, but I know that some plastics can, when cut with a laser, give off fumes and gases that will damage the laser cutter (eg PVC gives off gases that will cloud the mirrors). What materials would you recommend? (I've attached a quick sketch of the general shape of the planned spring.) EDIT: I've added a rough sketch of the project - a torch, cut from acrylic. The four projections are to bind it together with an elastic band.  The switch operates like a syringe.

Diode laser cutting capabilities??

Hey guys, Im starting to build a 2 axis CNC for a laser. I was going to try the DVD burner laser and just cut through some paper for now but im wondering what the capabilities of the higher wattage lasers are. I know there are several 1-2+ watt lasers on ebay, what could they mange to cut through? Could I cleanly cut cardboard? What about vinyl for making stuff like decals and stickers? Im wondering if spending the extra money on a better laser would be beneficial or not so if anyone has some good comparisons or ideas let me know. Im on a tight budget for this build so a co2 laser is WAY out of the question. This is my first CNC build so its mainly to learn but the more capabilities of the CNC the better.

Need a 30 watt "LASER"

Looking for an inexpensive laser cutting/engraving system. I will be taking it apart and  customizing it to fit onto another machine.  Currently, we have a rotating blade to cut sheets of material, but this set-up causes many issues.  A contact free solution would be best.  So I want to mount the laser carriage above the cutting area; the rest of the laser parts will be contained in a metal cabinet under the machine.  The laser would need to be able to travel 12-16 inches in 1-2 seconds and cut through 1-5 mil paper/poly material. I have a fair amount of experience with lasers, I have know how to sight them in and understand the technology.  We currently have 45, 100 and 400 watt galvo head lasers, as well as a 90 watt XY laser set-up. So, what website would you direct me to, to purchase an inexpensive laser system?

Trying to cut bike frames ( for physically impaired person ) ?

Hello once again, I've sorta been sneaking around trying to decide what the best way to go about trying to cut ( basically a bike frame ) without doing it manaually and = or spending too much cash I dont have. Welders look like they'd require a high skill level to hold and I cant really hold- or in fact even BE near things- that causes high or noticable rpm , so the hacksaw doesnt seem too great an idea either . But what i was thinking ,was that I could use some of sort of clamp set up so that I didnt have to hold the hacksaw while cutting the frame ( its really a knee walker frame ) If this seems like a good idea or  any one has any other suggestions or ideas that might allow me to do this  , i really appreciate your opnion on the best way I should go. thanks hele

Ingenuity Needed: Cutting records with quality.

It's lengthy, sorry, but it's worth it! Let me preference this with, I know this topic has surfaced before. Most of the forums and pages are filled with broken links to information, sold out products, and are all around rather worthless to return to. I'm posting this in hopes it stays a useful reference point. For  a few years now, I have been looking at cutting disks playable on a record player. I found an 'ible a while ago (the original one I bookmarked has been removed) that showed how to make an needle assembly. It demonstrated making a record engraver by putting a staple through the center of a speaker. This tool kind-of worked, but had some quality issues, as well as speed. When you push to engrave the audio, you slow the table. Less pressure, less quality, more quality, less speed. The other issue I ran in to was keeping the groove tight enough to hold more than 20 seconds. I'd like to construct a device that will cut CDs in to records with a good bit of accuracy, and give a second life to mis-burned disks (as well as some ancient unsupported linux disks...driver disks...early Windows builds...AOL disks...you get the idea) Putting the proper spindle on a properly geared motor should resolve the speed issue on cutting. Having the cutting arm on a servo should resolve the length issue, my only quandary is quality. ~~~~~ So, the point of this post, and the thing I'd like to have some input on is, How do I construct a cutting needle, that will offer some quality. I should refine that a little more - something that is going to transfer bass well. ~~~~~ I was not eager to puncture a speaker, so I modified the original plans. I placed the staple in a layer of plastic, and glued this to the speaker. The plastic gathered more of the vibration, and funneled it to the cutting head more accurately. This did work relatively well, but I feel with a few extra minds, this process can be made better. If this project ever sees the light of day, I'll make an 'ible, and cite any assistance. -Spence
