How to get the axle out??

In place of the rubber inner tube, I thought of using this..........

That makes sense to me.

Getting the springs a the proper angles with a bit of preload on each one, should help to stabilize the trailer.



There's also gas dampers available that are actually dampers. (They're not bouncy)

These ones are for RC cars, so they might not be big/strong enough? (but they're less than $10 a pair)

These ones are for cupboards and tailgates and support 90 pounds.

I'm sure that there's something available that would have the right pressure, length, and travel that would work for you?
 
I just received a post that a Thera-Band may work,
comes in several sizes and lengths,
I wonder if that would hold up..........?

That looks like a good option.
They look pretty durable.

Probably better than an innertube.
(I used to make slingshots with innertubes when I was a kid. They didn't work very well. Those big rubber bands for hockey pads worked better. )

It comes in tubes as well, if that's easier to work with?
Three tubes with different resistance levels for ~$20




(Actually, thinking about it,.. the Theraband might be kinda springy and bouncy?
An innertube isn't as stretchy, so it might be more "muffled" and have a better damping effect? (I just made that up.))

Well Guys,
I tried a bike tube for sway control......with 50#'s of weight, at the rear of the basket, as close as possible to the rear wheels, (1st test for the worst towing scenario for the most sway inducing results).

It does work, now I have to adjust the tension to get the proper sway reducing results.
4 wraps on one side and 5 wraps (different spaced bars), I'll add another wrap.
I used a 16" tube, I need to get a narrow road type tube, longer for more uniform wraps, for/on both arms, for better sway adjustments control.

For an easy way to see the tension on each arm, lay a straight section of rod/pipe down the center of the trailers length, temporary tape in place to hold it there.

Take the fish scale that goes at to least 20 #'s pull, tie a cord to the end of the bike arm arms, (thru the bobbin locking arm spots), pull the arm towards the straight edge, (about the same distance as when attached to the bike bobbins, for the arm spacing).

Read the poundage from the fish scale, (the inner tube wraps tends to pull the bike attachment arms outwards), repeat on the other side and adjust the wraps to get the same pull readings per side, and the twitchy trailer sway is controlled when hauling the load.
Don't cut off the excess tubing until you are finished testing.........Don't ask..............lol
More testing ongoing...........

Here is an update on more information I just found,
Update Update Update
A second option showed up while testing today, you can also use the cross bars on the bike attachment arms and the first cross bar on the front of the trailer.
This second option may provide better results, I used the the available Bungee cords
I had on hand., 24" long and 3/8" dia bands.

If you can find bulk bungee cordage, it may work better for better adjustment results, than the bike inner tubes.

See photo's here,

ps, looking at bulk Bungee cords........

Can you take a picture of your mounts and trailer connections on your chainstay?
I assume that you got your mounts built and connected to your chainstay?

I've never actually seen one in real life. 😁

Yep,
Done finished the trailer attachment brackets.
Had to make them for the bikes, as the usual way is to have the Trailer Attachment Bobbins threaded on the end of the solid 1 pc axle, that wouldn't work on these bikes, as the Bobbins would interfere with the derailleurs shifting pattern etc.

So I used 1/2" thick x 2" wide x 6" long Alum blocks, the used the mill to insert the "U" clamps for holding the Trailer Bobbins, have a heavy coat of Rubber Shoe Goop in the main chain stays arms, that were milled to fit the rear stays..
I only have 3/16" clearance from the top of the brake disc to the alum block,
reason for counter sinking all the bolt heads/"U" clamps etc.
Things are a little tight around the brake disc........lol

Pending photo's..........
Here are the trailer attachment Bobbins that normally fit on the axle,

I'm curious about the trailer attachment and those "circular clamps" as well.


I was considering buying an Old Man Mountain rear rack, but I had a similar axle issue as you were having.

They do have "bobbin" type attachments that thread on to the axle, but I've got a hub motor and the wire comes out the middle of the axle, so that wouldn't work for me.

The "bobbin" would simply replace the axle nut, so my axle would have been long enough.

Here are some photo's, click on photo's for enlargement.........

Full view, trailer hooked up in the right side, left side trailer arm is hanging there,
unattached.
The left side of the trailer attachment arm has the inner tube/Bungee sway control attached for testing.

Right side hooked up, showing trailer attachment arm on Bobbin, the lock is NOT locked down, needs to be pivoted forward.. the "U" bolt threw both Alum plates,
right end of bracket. Grade 3 bolts thru the rack bars and alum backing plate,
both sides are made the same.
The custom made backing plate, is the Black bar that the trailer arm is sitting attached to, 2 grade 3 bolts in the rack bracket.

Trailer attachment locking hook and attachment bracket in the back ground, showing the Trailer bobbin and the right hand end of the Alum bar.

Trailer Bobbin with the 7/16" bolt head and clearance between the brake disc,
3/16" = .186" look close.....lol

Hope this helps...........

Both my bike are mid motors, that was the first thing I checked when buying them, as I had the trailer bug, when buying etc.
You would have to have custom made trailer bracket/Bobbins for that hub motor.
