    Pro tip.
    You need to have a choke hose on your air to the gun. Two meters of 3/4” hose at the gun end will give you short pressure & volume over air. Use short bursts so compressor can build up and you should find that the gun works better.

    Although we haven't heard a lot about your mother ,
    she sounds like a loving & caring person who is intelligent & very supportive towards her family .
    It speaks volumes for your character & the person you are Jess.
    To have children who love you & are living successful lives, such as you are is the greatest joy for any parent .
    Im sure mum was very proud of you & your achievements,
    drawing much comfort & reassurance from her family .
    If we can celebrate the successful life of a loving parent who has moved ahead ,
    We are truly blessed .

    A Resilient Spring Grid Coupling would have been the best quick fix for any alignment issues and flexing. A BIG plus is if anything gets caught in the prop the coupling spring will sheer saving your reduction gears from any damage. Just rewrap a new spring around the coupling. Another TIP use a mechanical lock like wire lock or bend washers on the bolts and flang edge instead of using LockTight.

    May be opening a can of worms here but we no longer use spring washers on critical rotating assemblies due to there inherent weak design for high torque applications. It is much better to use just a flat washer and rely on the loctite(which has more than enough retention strength as you have seen) other than that, great work!

    I had the same problem on a 100ft trawl boat. He replaced the intermediate shaft and it did the same thing. I was there working on the brine water freezer and freezer hold so he asked if I would check the alinement. I tried for an hour and I get it .001 all the way around, them roll it 180*degrees and it would be closed on one side and .020 thousand on the other. So I told him he had to pull the shaft and bring it back to the machine shop and he told him he would beat my ass if there was nothing wrong. I said bring it to the shop and he called me 2 days later and said the cupping was out .022 out on the face. I didn’t have to go line the engine to the shaft because he seen me do a hundred times lol. No more shaking boat.

    I love what you're doing and have been following along for quite a while. I would respectfully suggest that split-ring lock washers are not appropriate for your use and would encourage you to research and use Nord-Lock washers. I come from the wind turbine industry and we found that split-ring lock washers actually do very little once they're squashed flat...which will happen, of course, when torqued. Wind turbines can be high vibration environments and the Nord-Locks worked very reliably. Then, with those, you could use medium-strength thread locker and eliminate the requirement to use heat for future disassembly.
    One more suggestion for work in tight spaces, where you may not be able to use a long enough breaker bar, would be a torque multiplier. Again, we used these in the wind turbines and they're fantastic.

    Have you ever had the propshaft coupling off, to check surfaces and key etc..
    and the coupling centre bolt (there's a list of possibles)
    Are the bolts bottoming out on the other flange.
    I would have liked to see you use Engineers Blue..
    Plastercine..
    &
    Dry Wipe pens also work, difficult work I use indelible pens.
    I did think you could check things when they've been running and warm.
    Is there a balance issue.. cold and hot.
    Put a dial gauge on the engine block at various heights and positions..
    Engine could need a couple of braces..
    and check mounts above chocfast and use big bolts to stop movement.

    Run out should be checked with adapter on the transmission, secondly is the register in the shaft flange concentric with the shaft, thirdly loctite is great stuff to use as a backup for a questionably engineered joint or fastenings are loosening due to another issue, forthly spring washers , a hangover from way back when things did vibrate loose, get some Cat hardened flats. Go to Hastings Deering, they every fastener and fitting you'll ever need, coppercoat or some other never seize is all that should be used unless the is nobility issue.

    • @ProjectBrupeg

      We did check the prop coupling recess and couldn’t find any measurable run out so we are confident that part was ok. Our ultimate solution is to add a flex coupling and rubber mount the engine but in Aussie that’s 10 grand right there for this boat. We will revisit flex coupling etc when the boat is in Asia as it might be more affordable at that point.

      Would love that but all up to do that on Brupeg is around 10 grand. Many changes need to be made to fit the coupling (itself only $3200)

    Stick the socket on the bar rest the bar on the floor, bump the boat into and quickly out of gear, done it before in a pinch, bit risky though if you dont take it out of gear quick enough

    I don't know about in marine applications but usually couplings like this are dowelled and the dowels take the load and the bolts clamp the flanges. Perhaps in marine it's different for alignment adjustment but accurately machined spigots would seem to contradict this.

    • @ProjectBrupeg
      @ProjectBrupeg  2 หลายเดือนก่อน

      I’ve not done alignment on lots of boats so only have this boat to go off. The two machinists we have worked with over the years are both marine specialists and seem to suggest it’s a normal coupling adapter. I’m sure other types exist but I have only ever worked with this layout before. Dame

    You got to find best way which isnt always the one that comes to mind in heat of battle....easiest way is remove the propshaft coupling then put the clock on the propshaft and clock the inner spiggot diameter of gearbox flange while turning propshaft then move the engine till close as you can get it.....both spiggots should be tight fit into flanges then all should be spot on when bolted up....this does depend on having straight propshaft and very little play in cutlas bearings......this job we always do on hardstand with prop off.....but after propshaft been out and trued , balanced and cutlas bearing clearences checked....we also do it without the throat packing....but you got it close enough while in the water.😂 prayers for family😔

    if the spigots are out the pcd on each set holes wont be in line because the spigot would have been used to line up the pcd on each set of holes

    If your shaft had a wobble in it that would translate into compressing the inner diameter (where it rides against the shaft) of your packing material - creating a larger leak through from the stuffing box and you'd have to keep tightening your packing gland (the part that compresses your packing into the stuffing box). You haven't had that problem that I am aware of, so I think you can assume your line shaft is true. (Ex U.S. Navy Engineer)

    • @ProjectBrupeg
      @ProjectBrupeg  2 หลายเดือนก่อน +2

      No haven’t needed to touch the gland. It’s a grease filled shaft with a bronze sand seal at the prop end, grease in the tube and a packing at the inboard end. We do get grease squeezing through the packing which we wipe off every few hours but we assumed that was normal (love to know if it’s not) and related to excess pressure in the grease needing to find an exit over time. We don’t get water because of the sand seal and full grease tube

      Very specific type of prop design. It’s good but mostly an outboard thing. It’s designed to reduce tip vortex and and increase thrust etc. this is something our nozzle does very well
