I am not sure where this is from or what it actually pushes but I sure would like an hour or two to play with it.

Looks like a log barge pusher I think. I have seen them or something like them on discovery channel they use them to move log barges around by the saw mills.

looks like a bantam tug,used on canals in uk.

The prettiest small tug I know - 1910 from this page:

Two VERY small tugs: http://www.flickr.com/photos/wsdot/2735777611/sizes/l/#cc_license
One from Toesup posted elsewhere. I do hope you don't mind me borrowing it. If you do I will get it removed.

Those are some amazing boats, and I do know that there is a company out there that sells either the plans or a model itself for the "Canadian Log Pushers"
I would really love to get hold of one for the lakes here, it would drive people nuts if I had that much fun.

You might enjoy this. Stability obviously isn't a problem!

How do they go Ahead to Astern to quickly?

Any smaller and you would be riding an out board on it's own!

Don't build a model of it, just get a couple of large torque servos and you are off :-))
-
How do they go Ahead to Astern to quickly?
Many of them have a voith schneider drive which means that the motors run at pretty much constant revs & all that changes is the blade angle of the "prop". This means that full ahead to full astern is just the equal of changing the propeller pitch which can be very fast.
http://www.voithturbo.de/545950.htm - if you hold your mouse button down over the controls you can move the controls & the whole thing is animated. Remember you are looking down on the unit. The blades stick vertically down into the water.
Having a lot of power & not much mass helps as well!
Actually I have seen a few models of very large ships that were handled in much the same way as that tug!!!!! ok2
I find these advanced drive systems fascinating.
-
Didn't know you could get a commercial Voith Schneider units that small. :o
-
After watching the video, and the ones after it, I have to get one, the real one would be nice but I think the local lake would ban it really fast.
The models look great, and the video of one working is pretty cool too.
-
they dont have voith units dozer boats have a simular drive to a A.S.D tug if you look on this site it show you www.olympicdrives.com

I think that you are right & I am wrong. When I do a search for this there are boom boats with Voith Schneider drives but they are all much bigger. The broncs of this size are either steerable kort nozzles or the various steerable outboard leg type drives. As the latter were apparantly much the most common in later years I guess it likely that the one in the bronc in the video was one of those.
Funny thing is I am sure that I have seen pictures of broncs with drives sticking out the bottom that looked unbelievably like Voith Schneider units & not at all like outboard legs - but I can't find them now.
Thank you for challenging me & making me think.

Searching for the answer above I found this site with some lovely photos of very (the smallest yet?) tugs:

Specifically have a look at these:

http://angel.library.ubc.ca/cdm4/item_viewer.php?CISOROOT=/macmillan&CISOPTR=628&CISOBOX=1&REC=13
They look more like the motor boats that you used to hire in the local park when I was a kid but I am sure that they were as tough as hell & worked really hard.

Looks like it can handle well in heavy weather to. I found this on the 'related' links on the other youtube link.

For a moment there i thought it was going down :o , must have a really good seal on the decks .
I have just acquired a pair of schottles (the big graupner ones) and three of the smaller ones used on the seabeck kit . i plan to use the big uns for a new tug but the smaller ones would be perfect for a boot boat or even a rotor tug.
love the pics , keep them coming

I'm going to build one these great little tug.
Any more advice on the drive assembly would be good?.
Looks like the only suitable one I kind find is the Graupner Schottel Drive Unit I (1761) Drive Set. (A bit expensive :o)
Have the model plans purchased from 'trapletshop' but looks like the graupner unit would be probably be a to big to suit the 1ft tug on the plan.
Any help would be great :-))
-
Hi Roker
I would be interested in that build - pm me when you start please so I don't miss it.
I had never considered these tugs before.
Dave

An ice cream tub would make a nice hull for one of these - might try one when I've finished the schooner!

Have a look at this: :-))

I expect Krishna could come up with a plan of how to make the drive mechanism, Whats happened to him ?, he has not been on since the crash.
Len.

Hi Len
Krishna posted on the 28th so he hasn't disappeared (love his posts too)

krishna did a drive unit on here using a twin shaft one inside the other and a servo looked good and worked slug
