Piston Business Card Holders

The most common form of advertising is a business card.  When your looking for a customer to put faith in the fact you can do the best job the every detail in your business should stand out including your business card holders.  And most of the card holders look the same.  Give your mechanical minded friend something unique that says something about him or her.

I started out with this project envisioning a single design that was both anodized and etched.  However during the anodizing my power supply blew out the fuse and apparently the bridge rectifier.  Now while these can be fixed I decided to proceed with modifying the project to work without both processes.  I honestly think this was a good thing as after completion and I really liked the embossed look that I could never have gotten with my original idea.

For this project you will need:

A small engine piston (I used one from a 4hp quantum engine)
Soap and Wire Brush if you use a used piston
A Dremel Tool
A file
Ecrafter or Exacto Knife
Tape or in my case adhesive backed vinyl
Paint

Step 1: Clean the Piston

I started with 3 pistons from small engines that I had tore apart after they were junked(I came up with the idea when we were sorting metal for recycling). First off I had to clean the pistons as these were used items.  I put the pistons in the ultrasonic cleaner and then wire brushed them as you can see in the picture.  The cleaner the piece is the better it will look after painted.

This is so cool! I have a friend that just started working selling cars and I was looking for a business card holder for him as a gift and came across this and I think it would be so awesome.... wanna sell one? Or know who does sell them? Or have any other awesome ideas for old car parts? Thanks!

I have never really thought about selling them, to buy the pistons would be expensive, I pulled the ones I had out of blown engines.... I will see if I can find some others and might make them for sale.

What a great idea, checked out your other instructables, you are very creative, love your ideas. Keep up the great work and will be following you. Thanks for sharing.

Thank you, I have help my girlfriend is very creative, sometimes I just have to figure out how to do what she comes up with.

[DoDo729]

Well this certainly is the website to research on. Keep up the good work, both of you.

I wish I had seen this before my dad threw away some old 351 windsor pistons I had laying around.

you will come across more pistons I am sure:)

Cool idea!! I have made two different styles of clocks from motorcycle pistons; one mounted on its connecting rod and another by beveling one side of the skirt, then insetting the clock-face into the top of the piston. I just recieved the piston out of one of the 450hp diesel trucks that I drive. Wonder what I can make with THAT bad boy?? :-}

the larger pistons would be fun projects if I had a mill up and running but right now I am lacking the tools to handle anything that big. Though it will not be long till I can play with larger projects. I do already have a 9in metal lathe.

Heres an idea; bevel one side of the piston skirt so that the piston sits at an angle when your done. Then you could mill a slot into the back side of the piston for cards as well as have the face to inset a clock into. I'll try to take some pics and put them up for you.
Cheers!!

I will try that when I get a milling setup, that is on the waiting list :(

really like the bronze looking one, i think if you could do some decals of spanners or other tools then they would look really cool too. even silver decals on the last piston you show would look really well.
this has gave me some good ideas, we have done the ashtray thing in the past with commercial pistons with a bowl in the top, machine the bottom off and smarten up the top part and they look well.
thanks

I am planning on doing a few more with my logo on them to put out at other businesses. The flames do draw a little more attention to them though. The silver one was the first one I did last year so it was simple.
