I believe they were invented (or become mainstream)for the devlieg so you had a fixed bar for production work, once set the operator didn’t touch them.Microbore must of been light years ahead back in the 60s
I had a permanent kuroda and Narex and d'Andrea search on eBay set up but they're just mental nowadays. Wish I bought a set when they were about £400-600 used with all the bits.
Gave my Wohlhaupter boring and facing head away many years ago, hardly ever used it and I knew the the guy I gave it to would.
Also gave away my smaller one and I am kicking myself about that every so often I need very precise holes bored, and I have just got a small job in that I could do with it
I did...and it arrived 2 days later. .Will you lot pack it in. I'm getting enticed here.
I bought mine at a roup for about £20 many moons ago, prices are crazy now.....
Following Brad's comment about the prices, I had a quick look on ebay and I best get on and sort out the CNC familiarity as I could sell the Kuroda for about seven times what I paid for it
