If I had a customer require precision holes that small, I'd be the first to sadly admit the task might be beyond my skill set
I could claim I had that skill, but I'd be lying. I was looking for something in .5-1mm or so range, maybe. It would be relatively easy to make spade bits out of music wire in small sizes. They'd be good for light jewelry work, soft metals, shell and bone. Making anything like that to cut steel, probably not! Honestly, my desire to learn machining was a result of the step-father who expected Armageddon any minute now when I was 10-14. He was planning on living off the wreckage, where I wanted to be able to live better than that. He was raising my brother and I to be soldiers, and I wasn't all that interested.
I guess I should have known Harold Hall would have plans for a miniature boring head! The Kaiser boring head is also cute, but I expect it's way out of my price range! And I'm sleep-deprived, so probably wouldn't have recognized even mild sarcasm as such unless maybe it bit me.
I'll make it a point to make my sarcasm more biting next time. :-)
I figure the 1 (one) watermelon my daughter grew this year probably cost around $30, and it was worth every penny for the experience of doing it.
I don't ever see myself making drill bits this way, but knowing it can be done puts another tool in the toolbox.
Last time I grew tomatoes, we got one tomato. I figure that one tomato cost right at $300/pound. If someone else wants to try it, I'll let them, but I have proven to my (dis)satisfaction that I've got a black thumb, not a green thumb. Definitely agree about making drill bits. Not likely to do it, but glad to know how one could be made!
