I had scrap MDF, which I turned into a bigger, bespoke to my tools version of their tool stand. A very small faff to drill the various correct holes. Finished with leftover bathroom paint from my DIY cabinet
I also admire ADAs tools and accessories but if my wife found out that I paid 115 USD for a root tab insertion tool, she’d kill me.
So, I’m making my own at 1/4 the cost. Made a working prototype out of 1/4” PEX tubing, a 3/16 dowel, a spring and two oak drawer pulls. Inserted 20 root tabs for the first half of my quarterly fertilizer. I’ll me re-doing it again in 304 stainless as soon as I get the parts.
