So as you may recall, I hadnt placed the right type of liquid gasket on the water jacket seals, and needed to re-do everything I had already done. I figured I might as well get the other rotor finished before I tried to move forward. Second one went a lot better than the first, but I managed to grind one of the long side seals too short

Took a while to find somebody who would sell me 1 instead of 12, but ended up finding one. Pictured towards the top of the above photo is an old oil injector (in the jaws of the grabber) that I have started to cut open. Those things are tough though!

The water jacket seals need some truly horrific blue goop called Hylomar. Imagine a B grade horror movie where rubber cement comes alive and terrorizes a group of teenagers. Thats what this stuff is. Stickier than just about anything I have ever touched; smells like it could kill you, and half the tube is covered in warnings about touching the stuff. I went through 2 pairs of gloves putting them on, HIGHLY recomend them.

A lot less detail this time around; Stacking the pieces together is fairly established at this point I feel. Not pictured: trying to scrape RTV off of the aluminum rotor housings. I just used an old knife for the Irons, but I didn't want to damage the Aluminum. I ended up finding a lot of sucess using my thumb nails that I hadn't trimmed for a while. Not hard enough to damage anything. I read that wood is useable, but I didn't happen to have a conveniently shaped piece at the time

Instead of a whole team of people, it was just me this time around. I ended up going with a similar Apex seal method from 2 months ago: place the long piece and long spring first, then put the small spring and finally the small apex seal.

As you can see in this photo ^ the tiny piece of Apex seal is not sitting in the corner seal where it should be. thats because I dropped it in that oil channel right there.

Not wanting to take apart everything I had already done, and unable to flip the engine over due to my wooden engine stand, I was pretty down in the dumps at this point. Have you ever bought way to much of something and not wanted to throw it away, cuz you knew it would come in handy some day?

Enter a bunch of magnets I had bought to magnetize some warhammer models. Good thing I didn't go with the ceramic apex seals lol.

@Pᴀᴜʟsᴛᴇʀ2 Third piece on. Paulster This is the Eshaft right here. Basically the crank, but it also has some oiling properties. Here we can already see that the threads for that 54mm nut are not present at the top of the shaft.... because I have it upside down

I can't say for sure, but it looks like it wouldn't have turned at this step. Seems like the triangle wouldn't have anywhere to go. A result of the upside down E-shaft, I hope. The second rotor is a bit trickier because it doesn't have a gear to set on. The gear plugs in on top once the final piece is on and meshes with all those teeth on the inside of the rotor

Last piece on. Not pictured: placing all 18 of those long holder bolts and torquing them. Once that was finished, I went to turn it to make sure I hadn't totally biffed it. With Vaseline covered hands, I couldn't really get a good enough grip to turn the thing. "Ahh, I'll put the flywheel nut on and then I'll have something I can wrench"

Thats when it hit me. Watched the source material again to make sure. Then I layed on the ground for about 13 minutes dealing with my abject failure.

I thought about taking off chunks, the top 3 pieces as a chunk, taking the shaft out, flipping it around, then moving the iron to the bottom 2 pieces and back onto the top 2 in some sort of Tower of Hannoi problem, but after about 2 hours I decided there wasn't a way to do it that would truly satisfy me

So 2 nights ago I swallowed my pride (and some beer) and took the whole thing apart AGAIN. Got most of the RTV off, and it seems like the Hylomar on the water jacket seals is still good to go. Planning on building my 2.5th Rotary engine this weekend.

After doing it so many times, I'm definitely feeling a lot more comfortable with it. Hopefully I can avoid any more drama and put it together the right way this time.
