Step 1: The Idea
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
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 3: Safety Gear
Step 4: Cut the Wood
I cut the two peices to 200mm length
Step 5: Clean As You GO
Step 6: Tape 'Em Together and Mark 'Em Up
Mark the centres of the test tube holes on the top level with a pencil. I used a 45mm spacing both vertically and horizontally.
Step 7: Drill Pilot Holes
I used the drill press stop to drill right through the top level and approximately 3mm into the bottom layer.
If you are using a hand drill or press without a stop, a trick it to mark the depth that you should stop drilling on the drill bit using masking tape or similar.
Step 8: Drill Post Holes
Drill through the bottom level and approximately halfway into the top level.
I am using 8mm dowel for the posts, so I used a 7.5mm drill bit so that the dowels would be an interference fit with a tiny bit of sanding.
Step 9: Drill the Tube Holes
Use a spade bit or other large bit as applicable to drill the full through holes to hold the test tubes in the top level.
My test tubes were 21mm OD, so I used a 22mm bit.
Although it looks like I haven't separated the layers in the photo, the lower piece is just a scrap piece of wood.
Step 10: Admire Your Work So Far
Step 11: Create Divots
I couldn't fink my countersinking bit, so I used the bottom of a step-drill bit. I beleive dremel-type tools have round head bits that would be suitable.
Step 12: Cut the Dowel and Insert
Insert into the base level, hammer down until flush with the underside. I needed to sand them down just a LITTLE to get a good tight fit.
Step 13: Add Felt Bumpers
Step 14: Put on the Top
Step 15: Slim Down Corks
Use precaution for this step - it would be easy to also reduce the diameter of your fingers.
I used the end of the belt to take a bit off each side going around the cork, then used the top of the belt to smooth out the sides.
Take off a little bit at a time until the cork is a good fit. Don't take off too much each go - it'll end up being too loose.
Step 16: Fill the Tubes
Clean the test tubes using soapy water and allow to dry completely.
Fill using kitchen supplies that you (or your reciept) will find useful. I also went for contrasting colours for aesthetics...
- mixed herbs
- hundreds and thousands
- curry powder
and left one empty for my recipients choice.
