Comment about Jason being tired - your resilience never ceases to amaze me. Kia Kaha whanau.

So much information shared about engine/gearbox/prop shaft alignment. For Dame, even when aligned, it's still not perfectly aligned. Almost there. Jobs within jobs. Boat life. Amazing the difference when the engine bay is cleaned out and fully repainted.

You've come a long way Damien and the boat is looking great, and your not too far away from a launch either. Looking forward to that day. To see the smile on your face from all the hard work you've all done.

I love the sound of clicky-click-click (the torque wrench). Progress mates. Love when the Project BruPeg notification sounds. Cheers to the crew.

I went to one tenth of a mm and she seems nice and smooth but your going to be perfect, very nice.

Daminan, it is great to see you working so har to get the things in alignment. What I have learned from a long life as an engineer is, that no two shafts can be in alignment when separate parts are assembled. So always use a coupling that compensates for the malalignment. The coupling also prevents shockwaves and bendingforces from the main axle from ending into and harming the gearbox.

I'm here with you from the beginning, what an achievement! Congratulations, can't wait seeing you afloat.

Dear Jess and Damian, Willeke but in special I found this vlog very interesting because lining the gearbox with the propeller shaft is crucial for a long life of the gearbox and the same is valid for the propeller shaft itself and even for the engine in a way. You’ve solved this perfectly as well as a watertight tank under the gearbox. Brupeg is again a step closer for launching and your “to do list” is becoming shorter and shorter. We wish you all the luck of the world in getting Brupeg ready for launching and send you love from the Netherlands

Thanks Craig. Feel like we are getting there. Got the adapter remachines and took out 12thou of run out! Might actually be able to get the numbers to work now

Looks so good to see the engine and transmission sitting where they belong. Glad you found the source of the misalignment.

It is a shame when other's work is not up to standard. Install your corrected adapter and torque all the bolts THEN check for runout. If all is good THEN do your alignment. Take this time to scrape the outside edge of the shaft flange clean. You can use 3:00, 6:00 and 9:00 for the co-axial alignment if all 3 numbers match.

Love watching your logic and brain process...Keep going....

That chart you showed at 45:23 shows measurements in mils (thousandths or an inch), not mm. So your tolerance of 0.1 mm or less is 3.0 mils which is good for 900 RPM.

Amazing progress.. Can't wait to see the culminating of all the effort on launch day!!

Make sure you do the final adjustment after you put it in the water. That is where it is going to sit for the most part of its life. On the hard the boat might have hogged a bit and with all the cutting and welding putting unknown stresses on the hull. to make it easier, clock 3 and 9 then set 12 to what 3&9 are. The chart you were referring to is imperial. It looked like there was some crap imbedded on the faces of the gearbox coupling and the adapter plate. It is a lot of playing around to get it %100 but it is well worth it for piece of mind when a thousand miles from nowhere.

You prob have finished this but maybe this might help if you haven’t. Always adjust height of engine and GB first then as you make sideways adjustment this will not effect the height. You only need 180 deg rotation of dial gauge 3 points 90 deg apart is all you need. Get engine position first then push shaft back to it. Don’t pour chock fast till it’s in the water. You will need sole plates unde engine mount feet. Has anyone done chock fast calculations for this installation. I am only 500m away if you want me to come and chat about it.

BTW, regarding torquing: Learned from a car mechanic that the reason they torque to "tight" (ca 90Nm) and then do a fixed number of degrees is because it proved to be more accurate when you have high torque specs (for example head or flywheel bolts). Which made me a bit sad because I had hoarded an old beefy torque wrench /(because it'd come in handy one day), and when I finally thought I'd be able to use it, the spec's just wanted a specific number of degrees instead of an insanely oversized torque wrench :P

Making faces parallel on a lathe is actually pretty simple. Having a test indicator rather than a dial indicator is the key especially when you have a through hole in the center of the part. If it doesnt have a through hole you can make one,or you can bore out some soft jaws and you can easily hold .001 surface parallel. But yeah a surface grinder would be the easiest way to go.

@davidhtims

It’s relatively easy to get faces parallel on lathes because that geometry relies on the accuracy of the lathe and it’s related wear factors. What’s not as easy is concentricity of various cylindrical components if repositioning is required between setups.

@TrulyUnfortunate

@@davidhtims Even a clapped out lathe will give you parallel faces with a fresh set of bored soft jaws. Concentricity is easy if you have a Buck Chuck but those are far from cheap. And again using a set of freshly cut soft jaws really help. You can also wack the master jaws with a brass hammer to get parts to line up on an old chuck that has a worn out scroll and master jaws.

Hi both, been a while since I’ve seen in touch. As usual I float back to the surface. Suggestion, why not use a shim that can absorb the vibrations? All the best both.

I think you should pull the prop shaft back 3mm or so, depending on the adapter plate spigot length, to keep them apart still for checking runout. Measure exactly how far the prop needs to come forward and use feeler gauges with a shim to set that distance between the coupling faces, then adjust your angle and runout with feeler gauges and dial indicator. Slide prop shaft forward and you should be finished. If you set them up apart with the prop in final position, as you bring motor/gearbox back, the height will change and you’ll have to do it all over again.

Props on spending time to allign with your biggest fan!

Shame there's no room what so ever for a yoke between the prop shaft and reduction gears. Other way to align shafts is to remove or slide the prop flang back so you have that messurement shaft to shaft. 🤔🤔Flanges will never align. Take a secondary messurerment off the bildge brackets and ceiling to realinge the shafts. Once the prop flange is reinstalled. An over head cross lazer is a big help narrowing engine gear box and prop alignment.👉👉We do the same for pump to electric motor alignments in the U.S. Navy. Another trick for tight spaces install a flex coupling between the prop and gear box. To make up the difference and done.

look add Aquadrive antivibration system. No aligning and vibration problems.

Forget converting to steam - there should be some warp drives going spare now that Star Trek: Picard has ended.

Thought. Instead of messing up the paint work adding two "push" gearbox alignment fittings, can you just build two "pull" gizmos, that can hook over a convenient edge, or only require small non strategic welds away from the mounting surfaces.

I assume he is going to grout it, he explicitly said he is going to grout the transmission mounts, e.g. @44:30 "I want to get my dam in for the Chock Fast", I'd think he do the front mount too, the end of the one screw in the center is providing minimal bearing surface for long term operation, fine for static alignment but not so much for a running diesel engine bouncing through heavy seas.

I am glad you are doing the alignment to this degree of accuracy (I would have done the same) , check if the grub screw on the prop shaft flange is good and can hold hard reverse thrust, should you need to power away from rocks you wouldn't dream of the shaft slipping out when you need it most. I love your level of patience and accuracy y-all. I wish you many years of good voyages and good health .

That’s a real engineers woodsaw..

Why is it so difficult? Usually, alignment is important and difficult to fit into, so why don't you connect the axes with Universal Join?

Why not a flex coupling between the flanges, easier and noise damping.

check propshaft coupling run out before reassembly this will throw out alingnment also as to properly face align couplings you need to measure the same point on each coupling as you rotate both together

Are you going to fit a vibration meter so you can monitor your awesome work? You know. sipping your morning coffee with the overlay on the big screen wondering what sort of vibes the surrounding vessels are contaminating you with.

47:34 - Regarding the pivot point for the alignment being "too far" forward, is it possible to swap the transmission mounts port->starboard and starboard->port and move the pivot point backwards that way? Not sure if everything would line up, but if so, that would shift the points back from where they are now.

How about pushing the shaft up until the two disk are just touching then rotating the shaft so the two surfaces hone themselves to a perfect fit?

Yes the surface needs to be paint free to get an accurate reading. The outer diameter of the prop coupling will have been machined true when it was made it’s it’s practically impossible for it to go oval after that process. So yes it’s possible but unlikely to be out of round

What about thermal expansion of the shaft line ? Wondering if it is significant. Maybe necessary to offset in the cold state so that it becomes aligned in the hot state. You would need to know what the vertical growth is expected to be.

@jaytalbot1146

The shaft is axially constrained by the gear box, the only "alignment" shaft expansion would affect would be the sand seal. That might be why he compressed the O-ring by 3mm? But I'd expect the shaft tube and shaft to be at a similar temperature, the shaft might be a little hotter, but I bet it not a huge amount more.
