Hello,
I am making the valve chest and slide bar for my 3/4" miniature traction engine, both out of CZ121 brass. I need to bore out holes in them, both 8mm dia., one through hole (25mm) and one blind hole (30mm).
Can anyone direct me to a suitable boring bar? I'm having trouble identifying any, I do not have any small enough. I've considered reaming but surely boring is easier for blind hole.
