Ron,

I copied this to a new topic with new title so it pops to the top of New discussions

I'm using "no flat pneumatic".  Which means it is a mix of open & closed cell foam tires.  I've had one on my wheelbarrow for years now and it works great.

@Zmokin - Your wheelbarrow has one wheel in front in a very low center of gravity position. A top heavy BGE in a nest further elevated yet even higher is an accident waiting to happen. Sorry if I'm offending you - just trying to explain what accident in the future is probable. Good night!
I'm not offended, but now I am a bit confused by your response.  I understand your concern over center of gravity.  My comment to Lit was in regard to his viewpoint that I need to go with hard solid rubber wheels.  I'm a bit at a loss understanding how tire type will affect stability.  The medium egg I will be moving across uneven terrain (natural forest floor with hunks of exposed granite), and then rolling it up and over about a 3 to 4 inch step onto a concrete patio.

    Honestly tire type was never an issue with what I was trying to warn you about. Using a nest in the first place means it is top heavy and then the larger the wheel diameter the higher the center of gravity and the more prone to tip over...that's all. With the terrain you mention I personally would be inclined to bolt that nest to a much wider platform than just those 16" centers. You need a skid!

    Oh, It will be wider than 16" centers.  I was planning on ~20" centers.  And with the amount of weight I expect my base to be, I'm expecting the overall center of gravity to be lower in relation to the egg and the handler than the BGE nest design as sold.

    Here is the caster I plan to use, I will use 2 of these and 2 fixed (non-pivoting) wheels.

    That similar to the wheels I have. They work well, just make sure your base is solidly attached to them. My table was a little under engineered for even a slight hole and the wheel broke from the base.

    @zmokin I didn't realize it was a different type of pneumatic. I know both people I know that used pneumatics are not happy they did but thos emay be different.

     

    As far as it being top heavy thats not an issue at all. The added weight from the angle and the casters as well as the couple extra inches of width makes it very hard to knock over. Pretty sure it would take a football tackle to knock mine over now.

    Well, regular pneumatics are inflatable, just like your car tire.  I have regular pneumatics on my air compressor, dolly, & my son's wagon.  I have to re-inflate them regularly as they don't hold air as well as car tires do.  I had the same inflatable style tire on my wheelbarrow and when it got a hole in it.  I found a no-flat pneumatic replacement at my local Home Depot.  I'm absolutely in love with how well it works.  full heavy load and it rolls great over any bumps in the path and it never ever has a flat, it can't because there is no pressurized air to leak out.

    Yes, I remember your little accident.  Mine will be bolted to angle iron and to the egg nest.  I've built "erector set" type structures with small hard wheel castors for a large rack mount stereo system I used to have and then a big heavy TV set on top (back before flat screens were available).

    two fixed and two pivoting
    :D

    my only concern is them going flat on an egg table, and once they start to its a regular nightmare, maybe if you had a way to jack them off the ground when in position might help them from deflating

    OK, now that I have a job, I'm back into looking at my next egg purchase.  I found I can get 1/4" thick aluminum plate cut & delivered for $120.  This will be 24" by 24".  that should make for a strong base for mounting the wheels and the nest.  The plate will weigh 14 pounds.

    @Zmokin : you could be over thinking this.

    I did this a while back. Google "small nest big wheels". It is very stable. You would have to grab the angle at the bottom and heave to tip it. Or actually push it into the pool in my case. I would still be careful about rolling it over a ledge or drop of several inches, but that's just common sense. You don't need the heavy plate at the bottom.

    Not over thinking, maybe over-engineering.  Yes, I've seen what others have done.  But with my large plate, I will then add thinner sheet metal sides making the bottom into an open top box storage unit.  I'm probably about 4-5 months away from pulling the trigger, but I will post pictures of my finished product.  I will be rolling this up & down over a 4-5 inch step from dirt to concrete patio, although I might make a short ramp out of some split firewood to give it 45 degree angle to roll up and down over.

    Over-engineering then. If you aren't installing the plate to add weight at the bottom, then consider heavy gauge expanded steel to make a shelf at the bottom. The shelf is handy, and getting a piece of expando will be much cheaper than $120. Your idea of a short ramp is a good one if the step is 4-5". I added a pull chain towards the top of the nest to further minimize any chance of tipping when I pulled it.

    I will be buying the nest handler, so with 2 fixed wheels at the back, I can tip it some like a moving dolly to pull it up and lower it down the step/ramp.  The weight will help with stability and the thickness will give me a place to screw into for my box sides.  Then depending on whether I'm annoyed by the bottom cross members of the nest or not, I could cut them out after it is all bolted together.

    I had 8" solid casters on my nest. 4-5" step is extremely sketchy still without some type of ramp.
