3/4" INDESTRO RAT QC ISSUES??

[dimwittedmoose51]

Most rats I've taken apart have for the most part been smooth on the interior surface from the machining and plating process.  This one(the one that has the bent handle) has several grooves/rings in that bore that make me think it was either abused due to lack of lubrication, or left hat way due to cost cutting or maybe thay did it intentionally for lubrication retention.  The bore currently looks like a badly oil starved main bearing on an engine.

Anyone have any thoughts on this??

TIA

As i am fairly unfamiliar with wrenches, I have to ask, " Is rat short for ratchet?

That's classic tearout from a dull cutter, notice also the tree bark like appearence on the bottom? same thing, but what you get at right angles with a dull tool...(it's chattering while cutting)

Probably just trying to push out just a little more product before changing the cutters....
(Or joe was out for a quickie while the machine was chattering away...)

Hope Joe came back with a smile on his face....just glad I didn't pay retail for that "workmanship....

Also it didn't mater because in a perfect world nothing rides on that. Notice it isn't polished/worn at all? A drive plug riding there would have buffed up somewhere, but its not. Only the hole is polished out. 

 Its just a clearance cut so the finish matters none at all. The dull cutter cuts slower, but if its still cutting maybe you can get a few more before grinding the bit.  This one was probably a semi-dull cutter and a very heavy feed rate. Slower feed makes for a better finish too.

  People sometimes sand the back of cabinets they build. Drawer bottoms, undersides of tables etc. etc.
This is the mark of an amateur. Professionals waste no particle of time futzing where the sun don't shine.

Scott:  True, but try to convince my proctologist about that....lol

Moose, my take on it is that the bent handle was from cornering the ratchet way too hard. The resulting bearing damage was caused by low lubrication levels and no baffles in the sump.

"Honest, Mister Moose, it was like that when I took it out of your toolbox this morning."

Sometimes it is better not to know....

while back in the shop...

"Hey, sorry, we bend your 3/8 extension"

"How did that happen?"

"We were using it to wind the spring in the garage door..."

"uhh....don't tell me the rest"

A great laugh to go to bed on!!
