Hey Alex, like what's going on with these three posts, because they are all the same, except the attachments? Would you like one or the moderators or I to delete them for you?

Alright,

To day I made a mini rope tow
Just to see if I could do it, It took about 6 hours to build.

Here it is:







Dr Frankenstein:

Although I like the Idea I really don't think that that would work, as a matter a fact I think that it would just lay on the ground and pull the rope to it. And if not then I would think that it would place WAY too much stress on the lower hub/rim.

SkiBachelor:

I live on the top so I'll want the motor on the top of the Slope and the counter weight on the bottom.

liftmech

If you could do that for me that would be awesome. (calculate the size that the block needs to be.)

Thanks, in advance.

I also like the idea, I rather use that type of counter weight then my winch Idea. But I don't know about the 3rd sheve down (from the top) It seems as though it would get in the way. I think that I'am going to have the moter at the top of the hill and the counter weight at the bottom.

ROPE TOW:

I have a movie of my mini roe tow working to but I'm not sure on how to put it on the boards. It is about 25 ft. long and uses a 1/2in. rope. I had to place both of my shoes in one of the tire to make the tractor deliver all of its power to the one side, other wise it would just spin the side w/o the rope around it.

ok, thats all I have for now.

[Benbosnow]

dose anyone know how to make a rope tow??? i have know clue! i want to have a control planell at top and bottom and a phone at both ends.

Try driving the rope from the side you put your shoes on. Differentials have one side they favour, and you probably just put the rope on the opposite side. If that doesn't work, get a long piece of steel and drill two holes in one end to match two of the lugs on the wheel, then let the steel jam on the ground. When you build your permanent installation build a bracket to that side to hold it steady.
I'll see what I can come up with as to your counterweight. If you could get me relatively precise numbers for vertical and length I'd be able to get you a reasonable weight.

Benbo- read all the posts in this thread to get an idea of building a rope tow.

I see That My pics in my last post did not work, and nor did the movie.

:help: I think that I need a little help. Every time that I select my file that I want and click add this "attachment" I go's in a little box underneath. Then I click "add into post" (Thats were the problem is). It says  Mini_rope_to_010.jpg (135.53K)
Number of downloads: 112, and does not show the picture and it does not show that the picture was even uploaded. Ending in a result of only haveing text shown and not my picture. WHAT'S THE MATTER? (I had it working before as you can see from my first post). :help:

I found out how much the rope would cost spliced and shipped. About $536.60.
Thats for 4 600' spools of 3/4in. manila rope. So that is about 2400'. I am going to try and get to the store tomarrow and buy one of those 'measureing wheels'
that tell you how far you've gone. That way I can get an exact measurement. I'am also going to try and get the exact vertical ft. so liftmech can do the calculations on how big the "block" needs to be. hope fully I can eathier get another 200' out of the lift or maybe it is'ent as large as I thought, and I can save a little money .

[ISMrider]

now that you have your camera working on the site could you share a picture of the hill you are doing this on?

[Alexvb222000]

Ok,

I'm giving up on posting the movie for now. I can't get it to go.

Yeah I can take the pics of the hill tomarrow and I'll try and have them up before 4:00 eastern time. It'll be hard to tell (I think) because it's "peppered" with trees. There every where, but there is a small area that I had started on a while back that put a pretty nice hold in the top of the forest. I'll try to show the entire thing. And maybe a pic of my fan gun (that is not finished yet).

By the way, does anyone know about fiberglassing? I'am ready to fiberglass my fan gun and I really have NO clue on what I'm doing. The "suction" frame on the back is all framed up with chicken wire and ready to go. I just need to know how thick of a mat should I get so I can do as little amount of layers as I can -too expensive-

And by the way if your wandering, this is no small home based fan gun. It's got a full size trailer and everything. Sorry for going on about it, I'm just proud of it. But right now it looks bad with the see though frame half done and all.

If you can help, please do.

Thanks,
Alex

I can't see the pic...

[Alexvb222000]

I had typed what everything was, but for some odd reason it did was lost when I tried to post it. So I'll type it again here.


1.) Pic of the rims I have so far

2.) Pic of the hole in the tree tops that I was talking about

3.) Another pic of the tires

4.) Pic looking down from the very top of the hill

5.) Looking down the hill from about mid way down the hill

6.) Same as 5.)

7.) Looking down toward the half way point of the hill

8.) Looking back up the hill from the mid way point of the hill

9.) Looking down from the mid way point on the hill

10.) Left side of the midway point

11.) Right site of the midway point (notice how steep it's getting) :D

12.) Looking down the hill from the 3/4 point

13.) Looking up the hill from the 3/4 point (lot of trees)

Looking at were I want to put my rope tow. I want it to come straight up to the side of my halfpipe. I want the 'shack' to come off the halfpipe and I want to place the motor and electric panels inside.

A little closer look. The little bar holding the "V" part up is no longer there as of today. I needed it to be shorter, one to fit out of my garage and two to make it stop wableing as much. Looks much better now.

[ISMrider]

you have some weedwacking and tree cutting to do. nice halfpipe :) hmm i was thinking about building a fan gun but not really sure if i can do all the work.(I heard it was pretty hard)

[Alexvb222000]

Liftmech:
I was mistaken about the rope tow needing to be 1000ft. Seems that my feet are a little smaller then what a real foot is. The rope tow will run about 500 ft. maxium. The slope it's self is about 900 ft. But it also curves ab bit.

So I now have the length for you (500 ft) and tomarrow I will try to get the vertical height.

That kinda sucks though because I thought that its was longer then it is and I wanted a much larger run. But it is still large, I "thought" that is was bigger then it is so I guess thats a plus .

At least this cuts my costs in half. :D Now rope will cost me about 300$ (I would think, I need to talk to the rope guy again).

[snowboardguy]

how do you find vertical height? Some Trig? Or is there and easier way.

[Alexvb222000]

ISMrider :

It's to an extream point of hard. Mostly it's just the time and all of the errors that you make along the way. For example, I've redone the osilator on the gun three times, that takes about 10 hours from start to finish of continuous work on cutting welding and everything else (a radio helps pass the time)

I started it in oct. of last year. (plans) And to build a large one worth the money you'll spend on it and the amount of snow that it will produce you'll need a lot of $$$ equipment at your fingers. (Large welder, torch set, large air compressor, Lots of drill bits, Circular saw with lots of blades, etc.)

[snowboardguy]

Plus tons of water once it's done^

[Alexvb222000]

snowboardguy:

I think so. Thats the only way that I can think of finding it, But I think that it will get a little hard to do because the hill does all kinds of weird things.

[Alexvb222000]

O yeah, heres a pic of the pond spot that needs to be dug.

To find the vertical, can't you just purchase of of those geo mapping devices for like $100 or maybe you or your friends might have one already. They can give you the height at where you standing so it will be an easy way to find the vertical.

Fiberglassing seems pretty easy. I helped my friend out today to patch his surfboard, and all you really need is the fiberglass and the resin. You lay the fiberglass down, and coat it with your resin mixture and let it dry. It is quite an amazing thing. Once it is all dry, just sand the rough spots, and you are good to go. Ill talk to my friend to get the resin mixture, or you could go to your local hardware store and ask someone. It looked pretty easy, but to make sure maybe test on some foam or some other sufrace to test your abilities.

[Alexvb222000]

Kz:

I have the resin a fiberglass, but I have some questions about it.
Like does it stick to duck tape? or will the tape deteriate and the fiberglass be weak? Do I need to add a lot of layers and sand after each to make it smooth and strong? How thick of a mat do I need to use for large areas that are curved? How many layers of resin should I use?

Stuff like that.
