"Dowty" washers I think they are called?  I have them on a couple of banjo fittings here

People like me who have a few gen heads but know nothing of their innards could learn a lot from this thread and it's digressions

I wonder if it is WOK material?

It seems to me there's good basic stuff here I might like to refer to later - so possibly others are in the same boat?

Cheers

Am I right in thinking that hot-bulb technology was in place before diesel cold-start compression/combustion chambers were properly understood?

Must be somewhere around 10F/-10C?  or maybe 11 or 12?

Surely three or four bullets would be better?  Politicians breed faster than lawyers or lab rats

There's a Polar engine a lot like this in an old generating plant in town here, but it just has all the exhausts into a single stack & doesn't sound as good IMHO

Sorry for large pics and multiple posts, learning to use  new tablet

Pic shows full rack  1 inch of travel




Hey Butch,  when you have an image open in whatever viewer you use on your tablet - somewhere probably at the top of the screen there will be a little box telling you what percentage you are viewing the image at.  Those ones you posted are large-ish so maybe you are viewing them at 30% or something.  They will be shrunk so the whole image fits on your screen, see?

Somewhere else there will be a tool that says "resize".  If you are viewing an image at, say, 30% for it to fit on the screen, then if you resize it to, say, 29 or 28% you'll see it's a nice fit on screen usually with OK resolution, and a good size to send and for others to open at their end

Just a thought.  Every time you get a new tablet/laptop it takes ages to get it sorted - or that's my experience anyway

Happy 2019, Mike

Wonder if this guy was one of the students? https://www.youtube.com/watch?v=5B34BmTqWg4

All those years I've had a couple of those steel foot-rules in the toolbox & never knew what they were for . . .

Like cutting into a big old Macrocapa hedgerow tree and hitting a steel fence standard from 40 years ago with the new chain on your Jonsered

Cool.  Good to hear, Mike

I'll be interested to hear how you get on with bolts.  If you have found a grade of bolt that is tough & durable, I'd be very interested to hear what it is so as to consider using it in other applications

Whereabouts are you located with that bad weather, Mike?

Cheers

Mike, I could very well be talking through a hole in my head about that

I just know that over here there are hundreds of old Listers that ran for many decades bolted to a couple of bits of timber bolted to a timber woolshed floor.  Even after the timber disintegrated and the floor sagged - they just continued to run . . . .

On here there is a big thread (several big threads) about balancing "Listeroids" and about how some are "hoppers" and some are "drifters"

Have a look and form an opinion . . . .

http://listerengine.com/smf/index.php?topic=6158.0

Try the link above to get you thinking?  There are several such threads

Meantime - there's probably not much to lose by playing with different bolts?  However, if there are odd forces at play, and you lost two bolts during a running session without noticing & stopping - maybe there would be a danger of snapping a corner off of a casting?

Again, better-informed folks than me will know

Good luck

My own off-the-cuff diagnosis - FWIW - is maybe you haven't got a bolt problem . . .

Maybe there's a load problem, in that if there is imbalance in the flywheels, the forces they are generating as the imbalance rotates - maybe lateral, maybe vertical, maybe tangential - but all forces wanting to lift/move the base off its mounts . . . maybe those forces are greater than the bolts can withstand

If that is the case, imbalance may have to be addressed?

just my $0.02
