Tap Clamp

I picked up a “almost” complete lot of machining tooling for a set of lathes.  One item that was missing was a clamp for the tapping head.  I reasoned out a quick idea of how it worked and what was missing and did a quick sketch in Fusion and produced a quick part without the outer filet.  I also drilled the corners so I wouldn’t need to broach the corners. Saying still holds, if you can’t find it, make it.

Making something better. Hacking Lawnmowers. Deck Shaft Disconnect.

Sometimes I get something I really like and discover a big flaw in it’s design. In the following case, my nice shiney new riding mower deck shaft had just given way again.  I believe this was the third failure.

The pot metal frame and weak steel direct shaft was a problem and after spending several hundred dollars over the past few years I decided to do something about it.  Off to the big shop.  After some quick layout in Fusion 360 and a quick 3d print of the housing for test fit, I started work on the shaft while the mill was cutting the housing.  I’ve gotten 2 complete mowings now before fall and it works great.  I was pressed for time on this but I did manage to snap a few photos of the new shaft and threading.

I also had to slightly modify a new tool holder I purchased as the ways were too tight for my liking so that took a bit of time to finish up.  Now I have a nice shiney new dedicated HSS cut off holder and a mower that won’t fail me.

As a benefit the deck has never ran smoother and of course within an hour of mowing I found a bend cable plow blade.  The new shaft disconnected like it should and no damage to the mower.
