Hi there. Just wanted to let you know I’m still working on the Lunar SPORE project.
Work on the project today:
- I changed and added some things for the SPORE Pressure Experiment 1.
- I went to Home Depot to look at some of my option from yesterday’s post.
- Black iron pipe
- None of the Home Depots in the Tampa area carry black iron pipe. Mindblowing! I used to see this stuff all the time in other places. Even Lowes only had the 1″ diameter pipes. I would have to order anything larger online.
- HD had galvanized steel pipes, but again, only up to 2″ in diameter. Plus, galvanized would be awful for this application. The galvanizing would flake of from the impacts and contaminate the sample.
- Fence post driver stamp mill
- HD has one of these and it looked pretty reasonable. About $40. Unfortunately, it didn’t make much sense without the black iron pipe as the “hammer”. I walked around and tried to find a decent substitute but nothing seemed to work. The splitting wedge (see below) would have been great but it was slightly too big to fit.
- Modified iron skillet and hammer
- I bought a 2′ by 3″ (internal diameter) pre-cut PVC pipe. It wasn’t exactly the dimensions I was looking for but close enough. I also got a small, fine toothed hacksaw to cut the slot for the hammer handle.
- This is now Plan B (or is it C?) because I think I have something better.
- Iron skillet and splitting wedge
- I think we might have a winner here! I found a 5# wood splitting wedge made of steel that fits the PVC pipe perfectly.
- The idea is that I’ll attach a paracord sling to the wedge and drop it down the PVC pipe. Hopefully resulting in crushed basalt.
- If this works then I won’t have to cut up the pipe. Yippee!
- Black iron pipe
OK, so tonight I’ll get the paracord on the wedge and tomorrow I’ll take the gear out and test it.
