Re: What is This?
Are those iron bearings let into the ends? The cracking suggests so. That would up the weight.
Otherwise without bearings lignum would be a workable but expensive solution. That would agree with the look of the turned surface, as there is no obvious grain that you would see with old elm.It really is quite difficult to build an ugly wooden boat.

Re: What is This?
Nick, I'd like to think I'd have noticed iron lets but the thing was so aged and weathered I didn't notice any.
If you look at the other picture it's clearer. As I recall, the piece was completely symmetrical.
But I see what you mean about the checking stopping.
It must have been and I missed it, but only on the one end...Last edited by Tom Christie; 03-06-2016, 04:33 PM.Comment

Willin,
I joined the USN at the same time as you, but had no idea there were still diesel boats in service. I joined for the same reason. Don't feel bad, you are here.
Took me about 4 years to get to a Nuke boat but that was like a cruise liner in comparison.
Now that I think of it we did have a Chief who had just come on the boat who talked about being on diesel boats all his career. He was astounded at how good we had it.

I have heard the same things.
That's how I know how horrible it could be on one of those diesels.Comment

Re: What is This?
Yeah, living conditions on the diesel boats were pretty rough, but believe me, until you got qualified, the crew made life much rougher than that. Of course, once you got your fish you were part of the family and life got much, much better. Regardless, there was never enough water to shower and you always stank.
Living conditions on the nucs were much cleaner and roomier and no one was monitoring your water usage, but there was that whole nuclear reactor just one bulkhead away from you and nuclear weapons down in the torpedo room to think about.
I remember a lot more guys waking up screaming in the berthing spaces on the 2 nucs I was on than on the diesel boat.
All in all, the Navy was a 4 year turn in the barrel for me. Highly un-recommended regardless of whether you're on a skimmer or a boat.
As Upchurchmr mentions, at least we're still here. Probably wouldn't be the case if I'd let myself be drafted, so I guess I'm lucky.
Sorry for the sea story driftage, Tom!Plures Naves Quam Mentes!

Re: What is This?
I don't know where the density thing started. Elm was used for hubs because it was resistant to splitting, but nothing said that it was exclusively used. The bearings were usually cast iron. As for 'American wagon wheel', I think that when it comes to technology, the US Canadian border is of little consequence.
As Nick said, the long hub looks like a wheelbarrow hub, but the large number of spokes isn't consistent with western wheelbarrows. The Chinese were serious about wheelbarrows since Zhuge Liang 'invented' in 231. Never mind the illustration from 118, the big shot took the credit. They used more spokes on the heavy duty ones, but it is hard to find a pic with both long hub and lots of spokes.

Even sailing wheelbarrows:

Re: What is This?
Thanks Dave.
The density thing came from earlier in the thread ( Post # 15 ) where I mentioned that it was really heavy and I doubted it would float.
I agree the border between us means little as far as technology goes but it seems significant in the patent department - the zipper, Robertson screw driver head.
We had a strong Chinese influence here years ago. In fact, Victoria was the home to Canada's first "China Town".
Can you say opium? Ahhhh, those were the days.

Re: What is This?
Aye laddie! If you look at the extended ends as line spools, you may be on to something there. I've never seen wheel spokes that wide and thin, but I'm Willin' to learn.Plures Naves Quam Mentes!
