    Fabrication video, is it a sales gimmick?

    It's fascinating the amount of hate nice welding tables get. I've never understood it and frankly I just wonder if it's a case of "I never needed one of these so why would anyone want one?". I think part of it is a lot of machinists view welding and fab work as "low tolerance" or hack work that...

    Questions about running machine at 100% speed.

    Almost all the parts we make involve 2-3 ops on the lathe, then a couple mill ops. I run the lathe at 50% rapids, mostly because I don't like the machine sheet metal shaking. I'm not worried about wearing it out early or anything, I just don't like listening to the rattle. The mill is at 100%...

    How well is everyone doing with tig work on anodized?

    That's typical of welding anodized aluminum. Welding anodized aluminum is a whole 'nother world compared to unfinished aluminum. It's impossible to remove the anodization from the tubes and keep the finish consistent, and you want to keep as much of the surface anodized, especially around the...

    How well is everyone doing with tig work on anodized?

    Those look like Raymond Martin's welds, that guy is a master at his craft. Martin Marine Design for those who don't know of Raymond's work, it's pretty well known and respected on the Instagram welding community. I've done a LOT of tig work over the years and in my experience amazing welds...

    Installing compressed air lines in commercial space, any guidelines?

    Stan over at Bar Z has some good videos on youtube about installing an industrial compressed air system a few years back.

    OT: Prostate cancer, need I say more........

    My uncle had his treated with radiation, he's been cancer free now for about 10 years, he's in his mid 60's. As far as I know the treatment is pretty straightforward and not as invasive or have the side effects of removal.

    Ercolina bender dies machined incorrectly

    I recently purchased a CE50H3 power ring roller from Ercolina last December. I am happy with the machine itself, no issues with the tooling or the quality of the machine. I did a fair amount of research before purchasing this machine and there's not a lot of options out there for tube working...

    Delrin specific drill bits

    This is very important. Normal grinds will try to self feed in a lot of plastics, especially if your workholding is less than stellar. Even a tailstock handwheel isn't enough to prevent the drill from self feeding, particularly when you're breaking through and it catches the web. I've had it...

    Delrin specific drill bits

    We drill a TON of Delrin, both in the CNC and on the manual machines. Our problems were primarily with the flutes chipping out the backside of the hole when it pokes through, and we found the 60° point drills ground razor sharp would do the best. Blind holes in the CNC we just use a bog...

    Shop Pet Peeves

    Yeah, I guess I'd have words with someone using a drawbar as a slide hammer too. That is some real window licker behavior haha. The way you originally worded it was real confusing, because you do need to tap the drawbar to knock the taper loose unless you have a power drawbar.

    Working hours

    Part of the reason I became self employed is the freedom to make my own schedule. I'm not a morning person, never have been. I typically will get into the shop between 8:30-9, work until my work is done. Whenever that happens to be. I'm happy to work late occasionally if the job truly asks for...

    Stainless passivation dip tank and chemical?

    You're basically looking to do a pickling bath, which is some NASTY stuff. Without the aids of electricity or physical agitation, you're relying on the harshness of the chemicals to do the work. And believe me when I say you need some harsh chemicals to pickle off stainless oxides without any...

    Old Cincinnati Brake Press Clutch Repairs?

    I found a shop over near Warren, MI called Midwest Brake that re-lines and re-machines clutch components for industry. The sales guy I spoke with on the phone said no problem, a clutch this small shouldn't be much money to rebuild and they seem to have the expertise and machinery to tackle the...

    Old Cincinnati Brake Press Clutch Repairs?

    Positive. You can see the clutch hanging off the flywheel. Plus I've ran this machine before, as well as hydraulic cam machines and they behave very different.

    Old Cincinnati Brake Press Clutch Repairs?

    I'm aware of the cost of the tooling haha. Fortunately I don't need overly complex or fancy tooling for our parts. Plain gooseneck punches and a couple bottom dies will cover most of what we need. I'll add as I go. Do you know if the current Cincinnati is the same company? Like, do they...
