Thanks Condor,
Shimmy in the bike, has to be coming from the trailer.
Yes, I have a 1/8 inch toe in.
I had to make do as I used an aprox. 3x5 retangualr steel tube.
I mounted the torsion 1/2 axle inside the tube, effectively making a whole axle.
I than turned the axle over to create a low profile torsion axle, swing arms going up instead of down
There are 6 holes per 1/2 axle.
By the time I drilled the holes, reversed the torsion units to fit inside the tube I was going to have to either over drill the holes quite a bit or settle for a slight toe in or toe out.
I have about a 1/8 inch toe in as I am told this is OK and normally preferred.
I double checked the hitch point to wheel and I am aprox. 1/8 on the out at aprox. 53 inches from wheel to hitch point and other wheel to hitch point.
Torsion springs rated at 550 lb., trailer frame aprox. 150 lb. empty
Have about 100 to 200 lb weight in gear.
Have of hitch weight, cooler will be filled with carbonated beverages.]
Tires rated for 90 PSI at 1000 lb.
Loaded trailer with aprox. 100 lb, put 40 PSI tire pressure, took it for a ride with my wife in the van looking on.
Still a bit of a shimmy (wiggle) (handle bars ) (instrument cluster)( mostly with such a smooth riding bike I don't notice any shake in the instrument cluster. I have something in the instrument cluster that normally stops vibration.
I have a very short wheel base, aprox, 23 inches. This will be a contributing factor.
I had someone weld front and back supports on the homemade axle yesterday, thought that would take care of it.
Hard to find a good road in Manitoba, but it acted better last test(loaded trailer properly). My wife couldn't see anything wrong from the van.
I am thinking I am spliting hairs.
The engineer at Flexride said I needed to be 1/2 degree + or - from perpendicular.
As this a trailer, I found that hard to believe.
I am thinking it's as good as I am going to get it.
Any ideas though, I would appreciate.
take care,
Tom
