I don't drill many holes anymore......since I put the cnc plasma in my shop. On very small holes I will cut them undersized and then drill (ream) them with a cobalt drill (due to the nitride hardening that an air plasma creates on the face of the cut).....but on most holes 3/8" and above the holes are acceptable for use as bolt holes...and are accurately positioned by the cnc.

A few pics of parts/holes cut on my cnc (a PlasmaCam cnc machine with a Hypertherm Powermax85 plasma, also have a TorchMate cnc with a Hypertherm Powermax45 plasma).

1st pic, 3/4" steel with 1-1/2" hole. 2nd, 1/4" steel with holes from 3/16" to 3/4". 3rd 3/8" steel with holes from 3/8" to 3/4" Last pic, a bracket cut from 1/4". The tapped holes were plasma cut to .188 then drilled with a .201" cobalt drill (to remove the hardened surface), then tapped 1/4"-20.

I do the same thing with my Dynatorch cnc machine and my hypertherm 1000 setup.

It's only cheating if you don't have a CNC plasma machine...which I don't; but wish I did.

At the bottom of all your posts you say that those who can do and those who can't work for the gumint. Maybe you misspelled government but that is okay I'm not a very good speller either [hopefully you didn't mean it as a slurr] But anyway I wanted to ask you something about that but first let me give you a little detail before asking the question if that is okay. Last year I had a nephew that retired from the air force and he was involved in every conflict that our nation has been involved in for the past 24 years. I have had two retire recently from the army and they also were involved in every conflict that our country also has been involved in for about the same time. I lost two friends in the Vietnam conflict one was killed in about 67 or 68 and one was killed in 70 might be off a year or so but I will look the next time I go to the wall. My Dad and my Father in law both served during World War II. My Uncle was paralyzed during World War II and I reckon the US government paid their pay through the military. Now My question are you saying that these brave family members and friends couldn't or lacked ability, is that what you are saying?

Some of the recent retirees in my family still work for the government. One of my friends that was killed in action in Vietnam went to Sunday School with me and one was a high school friend.

There are a lot of [in my opinion] fine people that work for the government and there are some that are just hold outs bidding their time for a retirement but to label them all the same is wrong.

Than why are you still posting in this thread if you bailed out as you say you did?

I apologize for taking the original posters thread off of its original topic, but at the same time each time that mjcad enters a post he also enters these derogatory comments about a lot of people and I have been kindly wondering where he is coming from. He may have legitimate reasons for his thoughts or beliefs or he may just want to bash someone to feel good about himself. Maybe if he started a thread and explained it maybe it would help me and maybe others to understand him better. I brought out just a few of the people that I hold in high regard with the utmost respect, that being said I have also dealt with some government employees that were less than pleasant to deal with. I am also a union member and I know a lot of hard working union brothers and sisters that I am proud to know and they work hard on their job and a lot of them it is not because they are being bossed but it is because of their ethic. That being said I have known a few union people that I would just as soon not know but to bash all because of a few isn't right. If he is bashing Unions because of their members pay, then I have in earlier years worked at nonunion jobs and I know about the defrauding in wages by some employers and I know that nonunion sites have their share of people that don't have a good work ethic either and it is to the same degree and most often it is worse. I worked at a couple nonunion jobs that were really good places to work, but by far a union job is the best.
I have a lawyer in my family and I know a lot of people don't like Lawyers and they don't like them until they need one and then they change their minds.
Again I apologize to the other members for taking this thread off the original topic but if someone is insulting me or my friends I would like to know why since I don't know him and he don't know me. I too would rather talk about or read about drilling or burning large holes in metal than talk about this so again I didn't mean to offend anyone.
