Hi

I am starting to make my first cart, I am not that handy so I am taking my time. I have suprised myself by how well it is going.

:shock:

I will be using 25mm Aluminium tube as the main material, The wheels are from a golf buggy, they sleeve into a steel tube(which happpens to perfectly sleeve inside the 25mm Tube) and were held in by a threaded t bolt and nut welded onto the side of the steel tube. Anyway I have done away with this and sleeved it and used r clips to keep it locked into place. This will allow for the wheels to be taken off when I need to store them on my kayak somehow. this is where I'm at.

I need some advice b4 going forward.

The cart wheelbase is 900mm, is this going to be too wide?

The uprights are spaced at 600 mm, my Tempo fisherman I am getting is 820 mm wide at it's widest point. I have measured the Tempo in the shop and the rear bottom section ribs are aprox. 450 mm wide in the centre of the yak, so I think the yak will sit in between the t pieces that I will mount on my uprights. I plan to have these t pieces at an angle to match the progressing width of the yak.

I have made this unusual step of making the cart b4 I own the kayak as I will be picking it up on my holidays and I want to be able to walk the kayak to the waters edge comfortably.

I have attached two pics

Any suggestions appreciated b4 I move on.

Cheers

As you say 900mm is quite wide but that can only benefit with stability.

If you feel comfortable with storing the cart that size then stick with your design

Too much width is better than not enough.

Gday Mac Fish - it looks like you are using pvc connectors for the pipework? - my only suggestion is that I found with my cart that the pvc connectors are the weak point - if anything breaks it will be here. after mine broke for the first time, I decided to overlay the connectors with fibreglass, and then put some cheap electrical ties around them - and (touch wood) this seems to have given them significantly more strength.
If you are anything like me you'll find that you will need to modify the cart slightly each time you use it until you get it 'right'. good luck - half the fun with kayak fishing is mucking around with these bits and pieces!

cheers

Fisher, I have considered your point and I can see they may be the weakest point and they will also be bearing all the weight.

I thought if I filled the tubing and fittings with that expanding foam it may give it more strength, what do you think? :roll:

It will likely to be bearing some weight with all the gear stored in the rear of the yak for my paddles.

On another note, my friend has just decided to join me in my new venture into yak fishing and has today ordered a Viking yak, a Predator. Another guy to our ranks.

Anyway a thanks to everyones comments, they have encouraged me more.

Cheers

Here is the finished cart.

I did shorten the width by 100mm.

The second rail above the axle gives it more strength however there is some flex at the top near the t pieces where the foam covered rails are.

Also when it's on the stand with myself applying some pressure the is some flex on the bottom near the axle.

Time will tell if it works out, and until I get my kayak I won't really know.

Q. What is the right angle for the stand or is it just there to hold it in place while you lay your kayak on top?

If this works, in the end I may take it to an aluminium welder and do away with the conduit pieces to make it stronger.

Let me know how you think I can improve it or have I left something out?

Cheers

Looks the goods MF. Only way to tell is when you yak it up.

Comments:
It looks quite high. Don't know how stable this would be and what would happen if you drag it through say sand. Would lowering it provide more stability?

How useful is the leg in this sort of cart? Will it get in the way - limit your lift? I assume you can only lift the nose of the kayak so high before the leg digs in. This may also be problematic over uneven terrain.
Because of the length of your support arms, the resting cart would form a triangle. If you laid your kayak beside the cart and then lifted the kayak end onto it, the cart should correct itself. Besides, this type of cart probably allows you to lift the kayak end with one hand and flip the cart under with the other hand - its not like the plug in carts where you have align the cart into scupper holes - next to impossible fully loaded.

HiRAed has posted a similar cart of pvc on this forum.

Yep,I think your comments are right. I will drop the height tommorrow and I think you maybe also right in the fact I may not need a stand if this is done.

Oh well, as I said it is my first attempt and I think I will get it right tommorrow.

Thanks for your help, Philip

Its looking near the money now mate.

But would it be worthwhile putting a diagonal brace from one of the horizontal bars to an upright one; I think it would remove any flexing in the structure and make life easier on the PVC fittings.

The majority of alum ladders have a brace to stop twisting.

Also agree with Philip re the height

 

[PeterJ]

The only thing against the pvc fittings is that when you take it on sand they will be put under alot of stress and perhaps break.

With the Tempo being around 30 kilo's plus your gear it's alot of weight.

Nice job though.

Hi

This is the lastest instalment and this is what I will try first with the yak. Where I'm staying on holidays has all concrete and bitumen surfaces to get to the water so I will think about strengthening it when I get back.

I took that stand off and dropped the height.

So this is whats left.

I'm sure it will work on hard surfaces anyway.

Thanks everyone for the comments.

Those golf buggy wheel are so stable it stands up by itself.

Cheers

that looks good, similar to mine. Finished it now, but havent had time to take any pics.

 

[PhilipL]

Nice job from someone who claims not to be too handy.

 

[Guest]

Back to the drawing board for this model. The only good thing about this protype were the wheels.

Turned out to be unstable and not much support for the kayak. On hard surface would stay on but in the soft stuff the kayak would not stay attached.

I am going to a aluminium welder now to do it properly and change the design.

I will post pics of the new cart.

Cheers

Pity MF
Keep us posted on the results. Have you seen the paddle boy carriers? nice simple concept

 

[fisher]

Gday Mac Fish - your cart is very similar to the one I built. I found that I needed to run some light cord (loose fit) across from one arm to the other, front and rear. This stopped the 'arms' from spreading as the cart took the yak weight. Also attaching the tie downs to the arms front and rear stopped the yak moving around on the cart. But I agree - an aluminium cart will go a long way to solving the problems associated with a pvc cart.

Well here's the lastest. :shock:

If this don't work its all going in the bin and I'm buying a real one'. :roll:

I would like to get the real "Humble trolley" this time!
http://www.cadkey.co.nz

The real test for this trolley will be next weekend at Wivenhoe dam where I will need to trolley the yak to the waters edge.

Under load there is a bit of flex in the axle area and the t pieces coming up from it. I might get some fibreglass matting and resin this week and give them a bit more strength. I think the aluminium will flex but won't break.

Anyway check it out and give me some comments.

Oh, and my Mum kindly made me a bag for the storage of it and made it so some noodles would fit down the side. A nice seal of velcro sewed in all the way across the top. If I tip the kayak it will give me something to hang onto. :lol:

Gee Mum's are good

Anyway take a look

Cheers
