Step 1: The Idea

Picture of The Idea
I loved the idea and presentation of the front cover of Make:'s Illustrated Guide to Home Chemistry Experiments.

The whole science-techno vibe is cool in a steampunk kinda way. Surely a test tube rack would be the most iconic image of a "science lab", and what better way to bring it into the kitchen than as a spice rack?

This gift was made for a relative, recently moved out of home, who is beginning to get into cooking.

Step 2: The Concept

Picture of The Concept
I played around in Pro/Engineer, a 3D CAD program, designing a basic rack for the tubes. Commercial test tube racks are both expensive and not particularly attractive.

The width and thickness of the base and top peices was based on the scrap wood that I had lying around - re-use for the win!

This let me try out various combinations of row/columns, separation, and upper level height.

Step 4: Cut the Wood

Cut the wood you have chosen for the uppr and lower levels. I used a table saw, and cut two peices to size together to ensure they were identical.

I cut the two peices to 200mm length

Step 5: Clean As You GO

Again another oft-applicable step. Clean up as you go - it's easier in the long run. Do it after you make a mess in each step.

Step 6: Tape 'Em Together and Mark 'Em Up

Tape the two pieces together so that in the next few steps everything remains aligned. I labelled one end of both pieces to make sure I remembered which sides went together when I removed the tape.

Mark the centres of the test tube holes on the top level with a pencil. I used a 45mm spacing both vertically and horizontally.

Ah perfect I have been trying to find the test tubes in that size but most do not deliver to Ireland. I have been looking for test tubes and did not think "laboratory supplies" Thank you so much!!

I see your from and/or the United Kingdom. Is that right? In america, the hundreds and thousands are called sprinkles.

Ok, maybe is just a coincidence, but this thing, with the same use (kitchen seeds and spices, mostly) has been already for sale (quite expensive also) years ago in my country.
Yes, he mentioned that, but this is a lot cheaper, and you get the satisfaction of making it yourself :0)
