I work in a machine shop, and I need to photograph all of our machined parts for our records. These parts are mostly stainless steel, but I am not sure what the best way to photograph them is. I was thinking of making a small ‘do it yourself’ light box, but I don’t know if that will work well with metal. Does anyone know of any good ways to photograph metal?

i guess i didnt make myself clear enough in the last question… i plan on manufacturing at least a few hundred of these so i cant just run to the jusk yard and cut some out. i plan on stamping them out in a machine shop. what i need to know, is in your experiences, what grade of sheet metal worked best for you. i.e. high cabon, low carbon, galvanized… oh, and yes i am a girl, but i am also a manufacturing engineer, so i will know what you are talking about so please, get technical

Cutting ring and top tool is having thin rim to be ground in dies of tin metal components.

What’s the best tool to cut a neat straight slot along a metal tube ?

Reciprocating saw with metal cutting blade does not seem to work very well.

What should I learn first before working in the blacksmith workshop? Safety, Metals, Tools, other…

I am going to be using a Dermal rotary craving/cutting tool to make me a gold necklace charm.

What is the best metal to use as the base?
I need something that will crave easy but after I am done it will smash easily.

I am not going to be working with the gold I have someone els adding that.

I want something beginner under 3,000, ideally 800 or less. Willing to pay up to 5,000 if necessary for a good one. Are there any that work with metal And Wood… and other stuff like stone or plastic? What other gear do I need? What’s the best training? I applied for machine tool technology at my local tech school. Will they tech me the manual stuff or are they focused on CBC software stuff? Are there any hobbysized CNC lathes? Any simple man powered lathes still out there?
*sp CNC
I want to make pseudo-weapons, Geiger-esque sculptures, complex mandalas, useable art like vases. Detail heavy stuff.

How much are and where do I get raw material? Wood isn’t hard to find. What about metal? I’m even thinking about carving discarded scrap metal and plastic!
Would I be better off teaching myself off books? If so what titles and where do I find said books?

I am using my Dremel and it appears I am not capable of a free hand straight line!! It is for a computer case that I am….well…attempting to add a window too.
