Been wanting a rotary/wobble broach for ages , finally picked one up, so thought I'd make a small bit driver. Made from brass and titanium, It takes standard 1/4" hex bits . The grip is fitted with 2 ceramic bearings (entirely unnecessary)
Main goal was to stop chips and coolant from hitting the probe, it also stop people from hitting it accitentally.
I'm a 21yo engineer
Has anyone created a ball burnishing tool with multiple balls configuration (side by side)?
Any research papers or designs on this configuration?
Apparently there were only about 100 made. A forum post I found states they contacted Wohlhaupter and the company stated they have no info on it nor do they know the internals or possess a manual. Since it was made in the 40s or so, the people who worked on it are long since gone.
I am currently working at an Aerospace shop. It was was one of them unicorn shops till the owner passed 10 years ago from the stories ive been told. All the guys working here have been here 20 plus years, are super skilled and have decided I am worthy of being taught. His son took over and it was still one of the best place to be, but he sold the company to large private aerospace company shortly after I was hired. It was fine for about 2 years, but not the corporate side of things is getting to me. I have learned a shit ton, I am given tons of opportunities and my direct management and I have fantastic repor. The corporate side of things has now cut our bonus down to sad percentages of what it was. The raise numbers are set to comically small percentage and resulted in me getting the smallest raise I've ever have while still obtaining "maximum percentage of growth." They are killing off the job shop, highly technical work. They want production line Kaisan LTA work. Thats the business model. much less fulfilling for me, and not something I want even if im not stuck in the line of opororations but helping develop the lines. My previous job has offered me a position at a 4 dollar raise, but with no opportunity overtime. I was working 46-50 hours a week before all the changes but im not barely over 40 with my current morale. This other shop is much much smaller. I know the owner well and like him. The reasons I left the shop have all been resolved since leaving. They want to bring me back in as their lead machinist, setting up their new machines and developing their part numbers. I also help with product design with them, create manufacturing drawings, and would have a good amount of pull. The set growth model their seems to outpaced my current place of employment. So I guess whay I am asking is, do you guys think I should stick corporate or go more "mom and pop"? Is it worth sticking it out and learning everything I can from the old timers who are teaching me and developing skills in machining, or is it better to go somewhere else where I will fill more of an "engineering" role over time?
Thank you in advance. Just need some outside advice from someone who isn't affiliated one way or the other.
I picked this up off craiglist today and wanted to get some more info from the group. I wasn't able to find much online.
Looks like the center is a taper (probably MT1 but don't have any tools that size.) Tapped holes are 10-32. Table is about 8" diameter.
A few questions:
Does someone have a manual for this they can share? Or some general info?
How do I use the 0-1 indications on the inner dial? The primary handwheel seems to be divided into 120 minutes. The inner dial also moves the table when I rotate it.
Kinda long and all over here, so bear with me…
I have my 2nd review coming up soon. Currently I don’t feel like I’m making enough. For some background, I have 1 year manual experience, then went to a CNC grind shop for 5 years that primarily was toolmaking, now this’ll be my 2nd year in a CNC machine shop. So overall machining I have 8 years experience. I started classes last year for an apprenticeship program, so this is my 2nd year. My current pay is just below $21/hr. For what I’m doing as an individual, I feel I’m underpaid, but I’m not entirely sure if it’s normal wage, or if I should be asking for more. I’m basically the supervisor on my shift, the only thing missing is the title. Fixing stuff from other shifts, reworking hundreds of parts in orders that nobody else can get (both because they don’t feel like it, or just don’t know how), training others, will to learn, and always looking to learn more, etc, I even know what everybody’s doing on my shift, and can help others… and I was the only person on my shift who had access to get tooling until I told management we need a 2nd in case I’m not there….anyways… with my review coming up, I’m not sure what I should ask for, my first review/raise (70 cents) left a sour taste in my mouth with the excuse of sending me to school, which seeing the bills for each semester, really isn’t much, it’s $400-800 for each course taken, and now that my cars paid off, I can manage that myself…
Question is, with my experience and what I do individually, what should I be making… I’m trying to use sites like Glassdoor, zip recruiter, etc. to find what I should be worth, but it’s ranging me from $18-$30 in my area, so I’m not entirely sure…
Hello all. This is my first post here, so let me start by saying I know I’m not a machinist and I don’t know what I’m doing yet — I’m just starting out.
I had the chance to buy a pair of Smithy Granite combo machines with a ton of tooling at an auction from a gunsmith who passed away. I actually bought my current house because it has multiple workshops on the property and is close to Murray College, which I hope to get accepted into for their gunsmithing program. All of that is to say I’m serious about learning this.
I managed to get the machines inside my shop, but I’ll need to build a base for one of them since they only came with a single base. I had some questions and I’m hoping I can get some help and advice.
First question: Is building a much heavier base for these machines worth doing? Will it actually make a difference compared to the standard cabinets they come with?
Second question: Assuming it does matter and makes a difference, what is the best base I can make for these that is still practical?
My idea right now is to build two bases using cinder blocks filled with concrete and rebar, with ladder wire running horizontally, and then bolt the machines to them. I’m not sure if I should also build the tray underneath out of concrete or just use the tray they come with. Open to suggestions on all of this.
My other questions have to do with the build itself:
Should the bases be bolted to the concrete slab?
Should I use metal shims to level the machines, or is there a better way?
Should I make sure the bases are perfectly level as well as the machines?
Is there anything I should add to the design other than a simple square slab base?
I’m open to suggestions and willing to put in the work if it makes a difference. Thank you all in advance!
This is a rarely used tool for me, but when I need it it’s the best thing around. This one, However, is shit.
Who makes a better one? A good one?
Wood mostly, plastic rarely, occasionally soft brass.
