Default HF Throatless Shear, or I bought a project

HF Throatless Shear
Last Friday I ventured into HF and came back with a throatless shear, or as my late dad would say, I bought a project. With 20% off, the bill came to $120 plus tax. This shear is a knockoff of the Beverly shear, and it really stretches the term knockoff.
After unpacking and getting rid of the cosmolene, a bit of examination turned up some major defects. The moveable blade casting has a high spot instead of a low spot for clearance, nothing is planar, and the thicknesses are all over the place.

Photo 1 & 2: Mapped out where the clearance should be and relieved the high spots with a (t)rusty angle grinder on the moveable blade

Photo 3 & 4: Thickness variance of the riser that anchors the moveable blade

Photo 5: First cut with a fly cutter. The castings are low carbon steel, not iron, and they cut real clean

Default Bought a project

Photo 6: Second pass after having to run down to Lowes and buy another set of Allen wrenches because my nephew decided to take them to his new job and then taking care of my tramming issue. The uncut square in the middle was knocked down with the help of said angle grinder since that area is not critical

Photo 7 & 10: Flipped over and cutting on the back side. There is a small area that didn’t get cut due to clearance issues, so said angle grinder will participate again

Photo 8: Back together. Turns out the gear part of the handle is now thicker than the riser that holds the moveable blade. That issue may or may not be addressed down the road. The sucker runs a lot more predictably now. One thing I did notice is that if the cut is started with the handle all the way up, the blade gap tends to fold the sheetmetal over instead of cutting it. More to ponder.

Photo 9: Replaced the chintzy Phillips head and slotted screws with socket head screws. Cleaning up the major defects introduced some weird geometry and clearance issues. Notice the gap between the stationary blade and the rear of the pocket?

If we all had the money...

What is in that glass? That looks like stuff that doesn't work well with machining. :-)

Looks like a good start on having good shear.

My 86 proof buddy Evan. As long as you take your time, it doesn't interfere.

IIRC, either Cutter or Dubby mentioned in a previous thread that the blades are prone to chipping. I plan to temper the blades back to a slightly softer state before that happens.

That was me, several years ago.
The original blades chipped immediately. Googling told me that the replacement blades had been performing okay. My store replaced mine without question & they've been fine ever since.
I suspect they would have used up all of the original run. Yours will probably be of the "new improved" variety.

Well, I just couldn't leave well enough alone.

Pic 15: Silver brazed a washer to the moveable blade

Pic 16: Finished with the clean up cut of the mating surfaces

Pic 17: Back together. The gap between the stationary blade and the moveable blade is somewhat less. The shear now runs like it should. I can raise the handle completely and start a cut with the material all the way in

HF gives you 5 days (I think) to return an "open box" item...

Two days of screwing with this thing...

Are you suggesting I return it now?

Where's my buddy Evan?
