I don't have the used pontoon yet, but they will run about 16 - 20 feet long and I'm not sure of the width of an average pontoon.

1) Not exactly sure how big? I would like it to swing/move out of the way when we are trying to transport the pontoon by trailer so the conveyor doesn't get in the way during travel.
2) Something simple but that is going to work well with out a lot of up keep?
3) Not a ton of money as we are just getting started with the buisness and have put a lot of money in other parts of the business.
4) Weld or bolt should work as my father in law is really handy.
5) Couldn't really tell you as we still have ice on our lake, but most of the weight comes off as soon as it is out of the water. We used pitch fork and it was really heavy to lift a full fork out of the water, but about 2 - 3 seconds later the weight was not to bad.

Hope that helps, not a very good description on my part but I tried.

Thanks again for all of your help and great ideas on this project.

I had someone else come up with another great use for the pontoon. He said that they have seen a pontoon used to reach out and lift a dock slightly of the shoreline and then the pontoon backs up pulling the dock out into the water for spring set-up.

Not sure how that would work either?

THANKS !!!!

I'm starting to get curious about what you mean by 'pontoon'. To me, that's just a floatation device, and generally pretty small. It sounds as if you're talking about a barge.
In any event, I'm going to alter my scale and start over. Since your father-in-law is handy, I'll start with a 3/4" steel tube framework instead of a ladder; that should be easy enough to weld up. I'm still thinking motorcycle chains and sprockets for the drive mechanism. I'm having a hell of a time trying to get the hang of Inkscape, so pictures will have to wait. I might have to drag my G3 out of retirement and do it in Illustrator 10, but that restricts the time that I have available because it's in a very uncomfortable location to work in.
Anyhow, just wanted to let you know that I''m still on it.

really an interesting project~
curious about what is the average weight of a forkful of sea weed? a few lbs perhaps?

From the description, I'm guessing about 50 lbs. when water-laden and 20 lbs. drained.

Hmmm. I used google images to look for some representative pontoon boats...

Thanks, Berkeman; that cleared up a lot. I had somehow gotten the impression that he was talking about a single float, rather than a pontoon boat, and so couldn't quite figure out what he was up to.

Hi,

This is closer to what I'm looking for in a used Pontoon.
http://upload.wikimedia.org/wikipedi...ntoon_boat.jpg

But without the seats a very stripped down used pontoon boat (The two floats, deck which would be replaced with some type of mesh floor to drain the water from the weeds and maybe modify the sides to keep the weeds inside the pontoon).

Oh, joy. I finally figured out Inkscape enough to get some sketches done up, and now it turns out that it doesn't output any file formats that ImageShack supports.
Illustrator had the same problem, and I would filter the output through Photoshop. I tried that with Gimp, and the programme crashes every time that I open it. I'll keep trying to find a way.

Can you maybe scan the hard copy output, and post that in JPG format? It won't be as crisp as the original, but would let the OP start to see your ideas...

Or else, maybe see if Primo PDF Writer (free) will install its printer driver so that your Inkscape program can print to PDFs....

I'll give the scanning a shot. Unfortunately, ImageShack doesn't support PDF. It would save me an awful lot of trouble if it did, since that is one of Illustrator's and Inkscape's formats.
If worst comes to worst, I'll do what I did before we had a scanner; print it out and take a picture of it with my camera which outputs JPG.

Hi.

Thanks again for all your time and effort on creating sketches.....

Okay, I finally figured it out. I had to install Gimp on my boss' computer at work, since there isn't an Intel Mac version. So I save from Inkscape as a PDF, upload it to my thumb-drive, import it to Gimp, resave it as a TIFF, and upload to ImageShack.

I'm afraid the design isn't much, considering how long you had to wait for it. I've made no effort to put it to scale or even include any details; I just wanted to get an overview of the idea up for you while I work on it.
For the belt itself, some kind of tough mesh would be nice, but I'm thinking along the line of a strip of AstroTurf or other outdoor carpeting. Anyhow, here's the basic idea.



I really wish that I knew why all of the rollers in the chain are missing from the picture. They're still in the original.

Nice drawing, Danger. Instead of bolting the belt to the chain to move the belt, could you just use a rubber roller at one end that is powered, and an unpowered one at the water end of the ramp? The multiple bolting points between the chain and the belt may cause some tearing forces as the belt goes around the endpoints. Also, the metal chain may not weather very well being cycled through the water at the low end.

I went back and followed the links I posted earlier with the pic of the water skimmer boat. Turns out there is a weed cutting boat with some kind of ramp already commercially available, the "Weedcat". You can use google images to find a few images of the Weedcat boat, or try the company's website directly (which is not very well designed, and has some frustrating circular links....):

http://www.trashskimmer.com/weedcat.htm

The "Trashskimmer" model is for picking up stuff off the surface of the water, and may also be helpful in thinking about ways to do this in a home-brew way. Here are some videos (I didn't take time to watch them yet):

http://www.trashskimmer.com/videos/videos.htm


EDIT -- I just watched the start of Video #4, and it's pretty good. Good view of the ramp and operation.

Jeez, man... nice research! Now I feel like a total dummy for not thinking to check that out; since the OP didn't mention it, I just assumed that no such thing already existed.
I hadn't considered the possible detrimental effects of water upon the chain, simply because it doesn't seem to bother motorcycles in the rain. It does make sense now, though. Your idea about the rollers is valid. I just never design anything with them because I've experienced too much slippage in the past when trying to use them. This isn't a high-torque situation, though, so that shouldn't be a problem.
Your observation of the possible tear stresses upon the belt when negotiating a cog is something that I was a bit concerned about. I was hoping that keeping the anchor nuts absolutely centred along the links, and keeping the chain tension as low as possible, would minimize that, but I wasn't really sure.
Excellent observations, pal.

Hi,

Thanks for the initial sketch, I will show to the father in law and see what he thinks.

I did find a couple of other websites that have the larger conveyor system but nothing that is for the smaller size like the pontoon that I can afford to start with. Here are a few other links for ideas, some may be to much but it looks like you wanted more research on this topic.

inland-lake.com/popups/hdbelting.htm

Inland's heavy duty belting tension rating is 1,350lbs per one foot of width. Using 1" x 1" flatwire belting with 6 gauge rods, our customers get longer wear, less distortion and less maintenance. (May be to heavy for this small of a project or too expensive for me?)

inland-lake.com

Most of these large harvester machines cut the weed and then it goes up the conveyor as they drive to harvester ahead. These harevesters are very expensive and don't have the ability to go into the shallow water by the shoreline.

But being that we are cutting most of the shoreline weeds by hand standing in the water we needed a pontoon style boat with a conveyor to carry the weeds to the dump location.

weedcutter.com/gallery.html

This is a cheaper/smaller weed harvester that we looked at but it still wouldn't pick up the weeds from the lake as this is another reason we are looking for some type of transportation boat or pontoon with a conveyor system to make things easier.

P.S. - Our current website is lakeshorepotential.com so you can see myself and my son and what we are working on trying work up to in the future.

Thanks again for all of your help and ideas as we really didn't know how to get past having to handle the lake weeds several times and would really like to figure out some type of conveyor system to make things easier for both of us.

LakeTetonka - Sorry I couldn't post any URLs to other sites until I have made 15 posts or more so I took off the http and www
