Bridgeport issues

If timing helps, there was a person using a long drill bit like the one in the photo at 5:30 - 6:30 Sunday during the HAAS practical portion of the class. It looked like they were working on drilling a hole (longways) into a flat pinion style gear.

I left after that, so I can’t say 100% that was the person in question but 6:30 is before 7:41.

From my point of view that is the whole point of the DMS. The fact that people don’t feel comfortable asking for help for fear of looking stupid or being belittled is the real problem.

If it helps, anyone who asks me for help typically takes priority of whatever else I was doing, and I try not to belittle while helping others out.

With respect to heavy machinery and “winging it” I think the main issue is, the person who makes the mistakes doesn’t have the feedback loop to know they did something wrong. Not to pick on the person who messed up the above, but the collet being bent doesn’t harm their work, and the parallels being out of true didn’t matter for how they were using them. The next person who wants true parallels and a tight collet is the one that suffers.

Also, there is the cost associated with the mistakes, which in the machinist world is far too expensive for the lesson learned.

With all of that said, I do agree that some people may be afraid to ask for help with the perception of our attitude being, “you fucked up, so you’re banned forever”. We should be working to change that.

I have looked at some of the footage but haven’t got that far into it.

Same here: that’s a large part of the enjoyment I get from the Makerspace.

I’ll also suggest a safer way of doing something if I see someone using a tool in a manner I feel is unsafe to themselves or the tool - better to offer a suggestion than to deal with an injury.

Part of the problem may be not knowing what to ask.
You have a task you need to get done, so you look for a means to an end - never mind the damage done in the process.

Pardon my ignorance here, is there a reason we have not went to an rfid system on these tools? I realize that a plc/relay solution takes some time to engineer but would seem to fix all that ails.

Thanks

That presumes that they were damaged on the Bridgeport. Obviously that is possible, but they could have damaged them in any number of ways we can’t imagine.

I believe in this case the collet was found in the Bridgeport

I was really thinking about the parallels, but yes, the collet is unlikely to be used in other ways.

We humans have this terrible habit of making up false realities to ourselves when we don’t communicate or take action.

I can’t speak for what they believe the reality to be in their head, but I can speak from experience of what actually happens.

Just about everyone who asks for help is treated with enthusiasm, I can site many examples over the years both from myself asking for help coming into this organization and from what I have witnessed of how others helping others. On the other hand I cannot think of a single time someone has been looked lowly upon or mistreated when asking for help.

It’s not the people that ask for help that are the problem, in fact, that personality trait is a tell tale sign of excellence. It is the person who has the attitude “leave me alone I know what I am doing” and the person who doesn’t really have an interest in learning the tool that are the problem.

I think the 3/16th Collet is damaged
It shattered my Carbide bit today

Please explain what happened. Thanks

When I joined in 2015, I had a vague idea on a milling project involving some interesting oval tube (example). The reaction I got from the people I spoke to was less than encouraging - ranging from “do it on a lathe” (yeah, really) to “hire a machinist to do it for you”. Quickly decided that I wasn’t going to get anywhere on that project at the time and almost dropped my membership.

Interesting project. Did you ever go forward with it?

Nope. Still have some ~20’ of the material - 1.50 x 1.00 flat oval, 0.125" wall, bright finish.

Would have needed to make some joints for what I wanted to do. I wanted the lowest possible profile, so a spline joint seemed like the best way to go, but snaking a wire around the perimeter would have been tricky. External couplings would have added bulk and been more trouble than I wanted to go through.

Well, now I’m curious. What’s the end goal of the proj?
What do you need to mill on the oval tubing?

Yeah - a bit off topic.
It’ll be OK.

I think this would be firmly in CNC mill territory. I don’t see an easy way to do this.

We were punching about 1000 holes in an aluminum pole straight up and down in aluminum tube. I have my own new full carbide bits for this. 3/8ths go fine, no problem with 1/4”, and then about 90 holes into using 3/16th the shaft about half way up Shatters. Tube is still held firmly in vice. Used a pair of pliers to pull the stick pieces of the bit and put up the colet. Then I walked around shaking my head trying to think of why that happened. I’m going to order another bit on amazon. Should I buy a new colet also? If so is there a certain type or name
