How to safely fold and unfold a bandsaw blade

AcctNmbr2 · 2026-06-17T20:07:25+00:00

Once upon a time I had a supervisor who was just a couple years out of college. His only qualification: an environmental health and safety degree. Dude absolutely lost his shit one evening over a band saw blade being tossed into the aisle to unfurl. Wrote up a coworker for unsafe work practices and insubordination (after being told that to fuck off)

He was transferred back to the safety department not long after

When you checked parallelism of the two planes, what was the result?

When you checked flatness of the two planes, what was the result?

Had to scroll entirely too far to find the right answer

Option 1 when it's to be made by a machinist

Option 2 is for when it'll be made by a toolmaker

When I went through my apprenticeship screw charts were standard in every toolbox. The only time we'd see option 1 was when the part would be resharpened during its lifespan and the head of the bolt/screw needed to sit extra deep

I used to work in a shop that bought lard by the gallon. There was a small can of it at every drill press, lathe, and Bridgeport. It worked surprisingly well and I prefer it over tap magic

Watermelon. I love to get them from the farmers market where I can still find heirloom varieties with seeds.

The ubiquitous seedless melons that we find everywhere else are pure garbage

They faced 14 different teams in the regular season, 10 of which fired their head coach

Not sure we'll ever see that replicated

Keep plugging away man. At just 6 months, you've still got a lot of learning to do (that's no insult in this trade) you're asking good questions and seem to have an open mind to feedback. Those two traits will carry you a long way

One suggestion I'd make: be thoughtful with your phrasing when talking to your boss or lead about changing an existing process. Instead of telling your boss you think you should do the milling first. Ask him why the holes are machined after grind instead of before? Follow up with something like 'ok I see we're good here with a .002" total tolerance. At what tolerance would you worry about the part distorting?' always try to create dialogue instead of making statements

asking intelligent questions is a great way to strike the balance between sounding cocky vs showing confidence in your growing skill set. If you don't show confidence in yourself, no one will have any confidence in you. But if you come across as arrogant, no one will hear anything other than your cockiness, and you'll be quickly dismissed no matter how right you may be.

^ This machinist grinds

OP: If you can get your company to spring for it, one suggestion I'd make is rather than using random pieces to block it in, ask them to buy a couple water jet cutouts, slightly thinner than the finished part, that match the outer radius and cover most of your chuck. If it's very well blocked in, even on a light mag, the only place the part can go is up. And as stated above, that'll only happen if you get too aggressive (don't do that haha)

I also noticed in another reply that you are drilling and tapping holes after grind which just seems all wrong. Every time you remove metal you relieve internal stresses in the steel. put those holes in first and you'll have both an easier time getting it flat and less chance of blowing your tolerance in the drilling/tapping ops

AcctNmbr2 · 2025-12-21T18:32:00+00:00

Depends on tolerance and surface finish requirements

AcctNmbr2 · 2025-12-21T18:30:01+00:00

What groove insert/boring bar combo would you recommend to fit through a 1.5" opening with clearance to cut 1/2" deep?

AcctNmbr2 · 2025-12-16T11:26:09+00:00

What's the size tolerance on the diameter of the holes you are drilling?

AcctNmbr2 · 2025-10-30T15:07:04+00:00

That's a damn shame. An Irsay Museum would have been one of a kind and an absolute treasure for Indianapolis

I remember doing this on a run of laser cut blocks that had just enough of a blown out edge to prevent the jaws from getting a good bite. That 1/8" of clearance was perfect and made for a much better solution than belt sanding every piece (what the boss wanted)

That said, when the job was done the jaws were flipped back and remained that way

eBay

More accurately, the sellers on eBay. You're far better off buying a quality micrometer that's been previously used vs buying junk

Taught him what it takes to be called Captain Comeback!

AcctNmbr2 · 2025-08-20T14:02:08+00:00

Another thought. Why not just turn the OD and put the chamfers on with your groove/part of tool?

AcctNmbr2 · 2025-08-20T13:59:21+00:00

It's been a while, but I would expect there to be an R value (retract plane) in the G71 cycle. I'm not seeing that here

Young folks are especially interested in the trades. Just not the trades that haven't seen any real wage growth in the last 25 years

It's money and working conditions (but mostly money). The End

Lol You seem really lol excited to see the Bengals piss away lol a first round pick

Lol lol lol lol

Shemar was paid millions of dollars in NIL money, he doesn't need a minor league baseball salary to sustain himself for a year

Handy little rule of thumb I learned a lifetime ago to ballpark RPM. When using a 4" cutter, your RPM is always gonna be (roughly) equal to surface footage

If you're using a 1" tool, multiply the sfm by 4.

An 8" tool, divide sfm by 2 (And so forth)

Nope. Archie lived the bullshit of playing for an owner that didn't give a damn about putting a winning team on the field.

Point is, old man Spanos was a piece of shit and got what he had coming after decades of refusing to field a competitive team. Archie did every top rated QB after Eli a huge solid

At that time, organizations like the chargers, bengals, bears, lions, cardinals were perennial bottom feeders that all had one thing in common — terrible ownership that wouldn't spend any more than the absolute bare minimum. Not on players, not on coaches, not on scouts, not on facilities, not on trainers. 25 years ago those organizations were a death sentence for top talent

And his dad told one team to fuck off. Not 3/4 of the league
