May I ask about wheel Bearings?
 
3 Attachment(s)
i'd like to have these wheels suport and function like those on a lawn mower or yard fertilizer. these certainly work, but not very well and end up damaging the wood frame.

this is the chicken "tractor" they are used to move - http://www.backyardchickens.com/web/...ractor-cooprun. no ideas on how to affix wheels have come yet.

any ideas? i don't have a welder.

let me know if this post belongs in another forum...

You need a straight Axel-The bolts move in the wood and will soon rub the side of the frame.

Your hardware store will have 1/2" steel rod in lengths long enough to go all the way across the frame and stick out each side long enough to put a stack of washers--the wheels--another washer--and a cotter pin.

The only tool you need is a hack saw and a drill(to make the hole for the cotter pins.) There are screw on caps made to avoid the cotter pin--however I find they fail a lot.

Better wheels--with bearings-- may make your cart more usable if it weighs a lot--Harbor Freight is one source.---Mike---

Use Tee Nuts http://thm-a02.yimg.com/nimage/78934ebd20023dd0

Very good advice here. I'd also move the cross brace back to where the wheels are now and move the wheels out to the brace position so they extend beyond the frame ends, then cut a little off the bottom corners of the frame at a 45 degree angle. As it is right now, you don't have any ground clearance when you tilt it up to move it.

i'll look at switching the wheels and cross-brace. possibly cutting the frame back. i'm afraid any more screws or holes will cause the frame to crack badly. it is old wood.

Thanks all!

Just about any big box store or decent hardware store.

Box store? as in a place that sells cardboard boxes? Home Depot and Lowes have shut down most all locally owned hardware stores. :tank:

do the "Tee Nuts" have threads? it seems if they didn't i could use "hayewe farms" and "oh'mike's" ideas together.

Big Box store means Lowes and HD among others.

Yes the tee nuts are threaded, If you use them on the outside of the board and the nut and washer on the inside then the
wheel will be the only thing turning so the threads won't eat into the wood.

do you mean a threaded metal rod? i thought you'd suggested a rod w/o threads and am wondering about the "nut."

THX!

hayewe farm 06-13-2010 03:41 PM

I'm talking about what you have now. The wood gets torn up by the threads on the rod. The Tee Nuts will prevent the threads from being in contact with the wood. By reinstalling the nut and washer on the inside you will lock the units together so only the wheel turns.

If you are planning on going to a steel rod across instead, you should install sleeves in the wood to prevent damage.

rosco 06-13-2010 06:35 PM

Right. the objective is to minimize wobbling of the wheels and maintain what integrity is left in the wood frame. What is recommended? a steel rod across w/ sleeves or the Tee Nuts with bolts?

sorry about the confusion. i'm prone to it

hayewe farm 06-13-2010 06:55 PM

Either will work, it's up to you.

rosco 06-13-2010 07:33 PM

What will be the secret to minimize wobbling?

A solid axle like I mentioned will not wobble--this could also be attached to the bottom of the 2x4 frame

using metal pipe fasteners--thus giving you a bit more ground clearance.


Take a look a a garden cart (like garden Way) these use a straight axle and wheels --with a ply-wood box on top--Holds a lot of weight--no wobble-

ah, the problem is that the 1/2"x4" frame must sit on the ground. i love the steel bar idea! finding one is a bit difficult. it is as if no one has ever heard of such a thing.

i think as soon as i find a 5' steel rod i'll use it with cotter pins. the design i dreamed up was to have the wheels detach. i only move the thing once a week. Popping wheels onto the bar, in only a few seconds, would afford the chickens much comfort.


To explain: there is 4"x4" wire on the bottom of the chicken tractor and the chickens already hate the wire on the ground. they'd stop laying if i lifted the wire off the ground.
