Ah, rust - my old nemesis

 So, the amount of force needed to remove thermostat housing bolt on the left, vs the bolt on the right ... not that much different. Left one is out. Right one is missing its head.

Engine Hoist supplemental

Image
I took some measurements and designed a "Dancing Chic Productions" custom knob for the valve on the engine hoist. The first draft took about 15 minutes to design in TinkerCad and an hour to print. It was a little tight and because I built it just to size. It broke in half as I tried to remove it. I expanded the center hole by 0.1mm which seemed to be the only dimension that needed fixing. I reprinted with 4 perimeter shells and 40% fill density which is a combination that makes for good strength with a reasonable amount of material cost. I used PLA - PET, ABS or Nylon would be 'tougher', but I have very good results with PLA and it is so easy to print. Plus it was what was in the printer when I went to run it. Since it broke on the shank the first time, I reenforced the part where it actually torques the screw by making it oval instead of round. Just putting more material structure to back the turning force. The finished product took about 2 hours to print and used ab...

Not really a hateful 8 ...

It was more like one apathetic and one stubborn and 6 who just needed to be told what to do. The OCPOTI* gave me LOTS of good advice about why the motor was stuck. Some of it I was even able to follow. pistons are rusted to the cylinder walls, why not check the rod bearings, and that timing chain looks rusty. So I pulled a couple of rod caps and looked at the crank journal. Not only do the crank and bearings look pretty good - I think it is so cool that they stamp the "FoMoCo" logo and a registered trademark symbol on the underside of a piece of metal almost no one is ever going to see. A nice show of pride there. Mid-week, Other_Doug dropped by to look at the machine. I told him I was having trouble removing the crank bolt - and so he asked if he could borrow my breaker bar, put it on the bolt and threw his shoulder at it like he was doing the shot put. It turned right out. That seemed to ignite a flurry of activity - and so while the engine still world not turn, we removed ...

Catfish-ed

 Catfish Hunter that is. He is quoted as saying [the sun don't shine on the same dog's butt everyday]. Or maybe the phrase is [even a blind squirrel never finds a nut sometimes]. My favorite is [the race is not to the swift or the battle to the strong, nor does food come to the wise or wealth to the brilliant or favor to the learned; but time and chance happen to them all]. I set out today with the ambition to remove the transmission. I ended the day with the transmisson where it was at the beginning and covered in rust. The transmission is held to a mount with 2 bolts that go into threads on the transmission body. The mount is held by 3 bolts to a cross member. You get to the bolts for the transmission by way of two holes in the cross member. I figured that out as I worked. I did not see the transmission bolts at first, so I started with the ones on the mount - they turned quickly enough, but then I realized they are a bolt and a nut - I was just spinning the bolt on the top s...
