shear embarrassment

I've had a harbor freight knockoff of a beverly shear for a decade, at least. I've followed all the online advice about adjustments, improvements, blade regrinding, etc. For years i've been cleaning up slightly ragged cuts by planishing them flat again and running them along a flap wheel bench grinder. I keep the blade aligned and gapped per the instructions.

Somewhere in a drawer there was always a little bocx with replacement blades I bought from someone here. Once a year I'd stumble across them and think "Oh, I don't need those yet." After all, my original blades are only mildly chipped...

Well, today I had to take the shear outside to help a neighbor cut an 8ft long sheet into strips 2" wide. As soon as I hit sunlight, I noticed my lower blade had a definite crack 95% across it, just barely held together at the cutting edge. Finally, time for the replacement blades. 10 min to find, install, gap, etc.

And then I cried.

Well, on the inside.

The first cut was water jet smooth. Laser smooth. God's Divine Will smooth. Required no dressing.

I cried for all the time I'd wasted cleaning sloppily cut edges... easily tripling the time to make any cut. I cried for the wasted energy, electricity, abrasives, etc. I cried for my own pigheaded frugality that made everything cost MORE just to save on the use fo a little set of clean blades.

40 FEET of smooth perfect no additional work cuts.

Sometimes [like the last 8 years of work] i make more work for myself out of stubbornness.

Y'all probably already do this, but check your shear and keep it sharp. Saves a heck of a lot of embarrassment, even if just internal.

Edited to add this image, both cuts direct from the shear, no cleanup. New on the left, old on the right.

Set aside a few bucks when you can to upgrade.

Yeah so where did you get the replacement blades? I would have replaced mine long ago just for the one chip right at the back where every single cut starts.... but I am not sure who sells them.

Or better yet, buy a B2 and keep it gapped for thick, and keep the perfectly functioning knockoff and gap it for thin. Works great for me.....

I bought them from Clang 6 years ago. viewtopic.php?f=3&t=105403&hilit=shear+blades

They're unavailable now. I vaguely remember someone [here or on Anvilefire.com] saying that real beverly replacement blades would fit the HF shear. Looking at the blades, I think its possible to simply make replacements out of O1 flat stock. Just need to get the curve right.

95% of what I do is .060 and thinner, so I don't think I'm spending extra for a real Beverly anytime soon. I have a band saw for really thick stuff.

These look extremely close to the HF ones, and I've seen the eastwood shear first hand, it might as well be the exact same casting.

There are a handful of company's selling beverly knockoffs.
It wouldn't supprize me if there where just rebranding at the same factory.

That's exactly what's going on -- they're all from the same Chinese factory, and just maybe there are replacement shear blades available on one or more companys' websites.

Or you go find a regrinding shop you like locally. They can generally cope with this sort of thing. If you have a band sander, you can generally cope if you can reliably maintain the factory angle. You need an angle-adjustable table to prop the blade on.
