174-000

Often I run impromptu sessions in the garage. These times are usually highly satisfying for me as they usually occur when I have just cleaned the shop, everything is organized, and I have available to me the equipment and supplies. Often I spend the time, when I should be sleeping, laying awake brain CADing the next project. The spontaneous projects are great because I just start to wing it and make whatever I have work.

I have a couple of friends that work at the local Audi and Hyundai dealerships in town. The Audi friend is a service manager and the Hyundai friend is a partsman. I figured their desks may benefit from a customized, one off, business card holder.

I scrounged around the shop looking for automotive related parts that I have stashed in various corners. I collected a few components that would lend themselves well to some modifying and decided to build some unique card holders. Below are the pictures showing what I came up with off the top of my head.

Sorry, no shots of the milling of the piston top. The first card holder consisted of a old BMW piston and an aftermarket rear spring lowering perch for a mk4 VW. The piston top was milled to fit business cards and then both the perch and piston were polished.

The polished piston top was taped off and the bottom half was the glass media blasted.

The Glacier White powder coating was fogged on and the assembly was baked.

I plotted out Hyundai decals on some gloss black vinyl to add to the customized look.

Done deal! Quick and easy.

As you may know I am I big fan of retro and vintage styling. I keep the polishing down to a “not so gleaming” level as I think it looks better.

The spring perch height was a little too tall so trimmed it down a bit. The base was cut on the lather in order to ensure it would press fit into the piston base. The jam nuts were left untouched.

I think the style suits a parts persons desk.

My next card holder took a little more machining. It started out with a rod of 6061 aluminum. I offset it in the lather chuck and drilled an off center hole straight through. I have a four jaw chuck that allows me to offset the stock properly however in this case I was lazy and the precision was not required so I opted to just toss a spacer into the 3 jaw. It works.

Onto the mill where I used a ball nosed end mill to cut some slots through the narrow side.

174-110

Next I moved onto a section of 1.000″ 6061 solid square bar where I dropped an end mill part way through it.

174-120

Next I hogged out a section where the business cards would slide through.

174-130

Onto the band saw where the milled bar was trimmed to length using a 45 degree angle.

174-140

All the components would get bolted together so I drilled, and countersunk, the hole for the stainless steel fastener.

174-150

Here are all the components that make up the card holder. The large valve is from an air cooled Porsche 911 and the the small valve was from my Honda CB160 cafe racer.

174-160

The aluminum components received a brushed finish. I like it!

174-170

Both valves received a polishing.

174-180

An Audi rings decal was plotted and applied. Done deal!

174-190

The small valve was secured with a set screw. The large valve was press fit into the aluminum rod and the secured using the stainless steel socket head cap screw.

I hid a GG logo on the bottom of the 911 valve.
