Quick Pic: The View From Down Under

Today was board-shear maintenance day. We changed the blade, replaced some worn screws, and trued the cut. It takes two people to change the blade. One person under the shear (usually me) and one person to tighten the screws. We have the maintenance down to about half an hour.  A while ago we showed you the view from above, ever wonder what the view from below looks like?

That is not a very flattering angle. It’s a very good thing Rachel has a great sense of humor.

Changing the board shear blades

Today was board-shear maintenance day! It takes two of us to change out the blades on the shear. That’s me under the shear, and Jennifer on the right.

The arm-blade is easily removed. The base-blade has bolts holding the screws on, so they need to be loosened from underneath. Once the blades are changed we replace the clamp and check to see that it cuts square. I also put some new lithium grease on the catch basin gears while I was down there.

It’s always great to put a sharp blade on the shear. It cuts “like butter” and makes a wonderful “swishing” sound.

Note to self: don’t wear black pants on blade-changing day; and closed-toe shoes are probably a better footwear choice.
