      I was only thinking that exact thing; when Joel mentioned about tightening the bolts via the holes in the gears by slightly turning the motor over, and Rob unsure what they were going to do? Joel was actually a step ahead everyone.....he was already thinking about how to solve that problem before they got to it! 👍
      I kinda think this way when ever I'm working with someone even working on something I'm not an expert at? What I mean is, that Joel has a very good spatial memory and he can visualise everything in 3 dimensions to solve things?
      Where other people might rely (not saying Rob here I'm generalising) calculations, Joel is picturing everything inside the mind 😉
      So taking this all the way back to Joel's beginning, I have to hand it to Rob for hiring a media and camera guy that goes above and beyond his job!
      Now think about how many other UA-camrs are out there and all of their media/camera guys?
      What are the chances of getting someone like Joel? He's literally a 1 in a million..... So that comes down to Rob's discernment during interviewing👌 and that's something I struggle with?
      So I'm going to say congratulations right here and now and we haven't even heard it run yet, but after watching this video and everyone working together....I have confidence that this is going to all turn out great! 👌
      Oh one last thing, congratulation to Tyson on the entire construction of the 12 rotar because he did what 3-4 people did today having had no or minimal rotary experience prior! That's just kind boggling to consider...... And fuck me dead the precision of the E-shafts is just perfection 😲
      Can't wait to hear first start!

    Rule of thumb with O-rings is if what ever your sealing has pressure in it the O-ring fits tight to the out side if it has a vacuum the O-ring fits tight to the inside. That way the O-ring can't move and deform.

      @@dylanzrim3635 It's actually a really important distinction depending on where there is pressure and where there is vacume specifically and if you are trying to keep pressure in or out, or vacume in or out.
      That is if you don't want your O rings to collapse when you're trying to keep oil pressure from the open oil pockets behind the steels from getting into your coolant line because you put the O rings on the outside of your coolant seal groove because "pressure = seals on outside" when the pressure isn't coming from inside the line pushing out, it's coming from outside pushing inwards and would crush the seals if put on the outside of the groove as OP sugests, getting oil into the coolant lines. Think about it in the actual application in this engine. 😉

    Rob, is the gear spline also 60 teeth? If not, then you have a certain grandularity of adjustment.
    For example if it had a 60 tooth gear and a 60 tooth spline, then yes you would only be able to clock it by 6 degree increments. However, if it has a 60 tooth gear and a 40 tooth spline, you can clock it by 0.15 degree increments by changing tooth position of both the gear and the spline.
    The best combination would be a 60 tooth gear with a 59 tooth spline. That way you can clock it by 0.1017 degree increments.

    • @kasuraga
      @kasuraga 10 місяців тому +2

      Yeah, it looked like he was so focused on making the holes line up at TDC on every rotor instead of taking into consideration the fact that with two different spline counts, you have a LOT of adjustment in the gear timing by not caring about the overall position of cosmetic details like those holes. I learned that a LONG time ago that you could do that with gears. Instead of rotating the object you want properly timed and pushing it out of time, you keep rotating the gear till the teeth properly line up with your desired timing.

    @slcbuilds3687 9 місяців тому

    @41:40 where you talk about the oring for the oil pressure passage. It's definitely best to use the larger o-ring that fits on the outer diameter of that oring groove. For oring groove design when the pressure is on the ID (inside diameter) of the oring you design the groove so that the oring seals on the OD (outside diameter) surface. If the pressure were to come from the OD of the oring the oring groove would be designed to fit best around the ID of the oring. A bit of a word scramble there, but hopefully that's clear enough. If you can find the Parker O-ring handbook it explains everything in great detail. If not, PM me and I'll send you a PDF of it.
