It startles me that nobody already told you alcohol and operating machinery don't mix very well... Milling can be very dangerous if you don't know what you are doing...
First off some things you should know from a professional (yeah, i CNC mill for a living)
- NEVER wear gloves, not even the latex ones. If they are caught by the mill you lose more than some blood.
- NEVER wear rings, for the same reason
- Always wear safety glasses, mills can shatter and you have only one pair of eyes. There is a reason why they print this on mill casings...
- If you have long hair like i have, make sure it's out of harms way.
- Always clamp your workpiece securely. If you can't, make a jig or something to hold it securely instead of clamping it half assed and trying it anyway. Also a stable workpiece will alllow you to increase feeds when roughing.
- Heavy milling can produce alot of noise on unstable machines - wear earprotection in such cases and please lock all axis that are not in use!
- Use proper ventilation when grinding carbide mills. They contain cobalt and other stuff that is hazardous to your health.
- Use coolant when milling metals, it increases tool life. (even with bronze or brass)
- Tapping steel should be done with cutting grease, not with coolant. Softer metals can be done with oil or coolant.
- Reaming - the best result you get with cutting oil
Maybe i forgot some things to mention, but there are lots of people here on AO that can fill in the missing bits.
Good luck with making your ionized mag, look forward to see it soon!
