Chris's Build of Battleship Ohio Engine

[crueby]

Great day at the pond yesterday with the RC boats, we had a couple of the guys from the Toronto area come down to run as well. Perfect weather, one exciting rescue when one sub got some fishing line and a bobber wrapped around his prop (idiot fishermen). Another sub moved in to push the first one back towards shore, and then the other end of the same line wrapped around both his props, they wound up end to end and could move but not steer. Another guy sent out his rescue barge to help steer, and they all made it back to shore. Whew!

Back in the shop today, working on the bearing blocks for the reverse linkages. Got the center holes drilled in all of them, 8 with a larger hole for the center post. Am halfway through drilling all the smaller mounting holes in each of the blocks now...

When the holes are all done, I'll set up an arbor on the lathe to thin the perimeters down and form the bosses on either side. That will also get rid of the rounded corners from the starting bar stock.

Hi Chris,
this will look perfect. 🍻

Thanks Michael!

Once all the holes were drilled, an arbor was set up in the lathe to hold the parts in the center hole to turn in the bosses on either side. That went quick once set up, just swap parts and run the cross slide in and out once.


Here is the pile of bearing blocks. Well, one of them, another 8 blocks for the link ends that connect to the crank arms. I mis-spoke (mis-typed?) before when I said they were for the center posts - they go on the other end at the crank arms.


Not quite ready to assemble all the parts yet, still need two more sets, this time the bars that go between the blocks. Simple round bar, just need to be trimmed to length and have holes drilled/tapped in both ends of each for screws to hold parts for silver soldering. The longer ones on the right will be the horizontal links from the crank arms, the shorter ones on the left will be the vertical arms up from the sccentric straps.

Just piles and piles 'o parts, Chris!  Can't wait to see them all come together on this bad boy!

Your day at the RC pond sounds eventful! Glad everyone recovered their vessels OK. Latest parts looks great! Did the other shop elves dig out Boring Bar Bernie from the pile of solid gold blocks yet?

They had to dig him out, he had the key to the grog locker!

  bet those blocks were flyin!

This morning the eccentric arms were trimmed to length and drilled/threaded on each end. Here is the stack of parts ready for silver soldering at each end of the arm. After that will assemble a set and double-check the length on the links that go between the center posts and the crank arms before trimming those rods to length.

Nice stack of wishbones there!  What are you going to wish for?

Cheaper metal prices!

Two soldering rounds, one for the upper end, let cool, then did lower ends.

Letting that cool, then into the vinegar to clean up...

The eccentric arms have all been cleaned and had some trimming done on the sides of the plates for better clearance, got them assembled onto the links:

Now am getting the arms to go from the middle posts back to the crank arms made up. All are trimmed to length and drilled, need to tap some more holes in the ends for screws to hold the plates for soldering. Getting close to having them assembled onto the engine!

looking great!!! you most likely are the most eccentric maker among us
