Hi guys, I am building a wood turning lathe and want to keep to standard spindle sizes. I want to go with a 1"x 8 TPI but I don't know what type of thread it is. I want to order a die and thread the shaft myself as doing so will probably cost me less than having a machine shop do it for me but I don't know what type of thread these are. Are they National Coarse? Whitworth? What? You know what I'm getting at here.
I'd like to be able to buy all standard accessories from say Delta that mate to a 1" by 8 threads per inch spindle thread.
Please advise. Thanks
