Pigeon-Rat - Opel gambler build

[imiceman44]

When I get back from blazerbash and have it back up on the lift I'll have to take a video of the beam cycling. The only possible bind point is the heim joint at the frame side. The axle side can stay rigid because it is free to move through the arc the same as the beam.


Yeah, I assumed I'd need to do that, but so far I haven't seen any issues with binding there at all. My guess is the uniball is more for strength and durability. I could see a lot of hard jumps and extreme cycling of the beams wearing out those bushing fairly quickly. Luckily, the change to uniballs is pretty easy to do, so I'll just keep an eye on it for now.

I never had one so all I know is what I have seen with my friends and the research I did years ago.
The fact that there's a product developed for this means there's a situation where it binds.
From the geometry side of it, the axles swing in an arc in a vertical plane inline with the housing.
The radius arms swings in an arc that is 3 dimensional because the hinge point is on the frame but it follows an arc hinged at the axle.
So there will be binding on extreme stuff and droop.
If the hinge point is rubber bushings they will squish and take it and eventually fall apart.
If it's solid like a uniball or heim something will break.
Just a heads up.
The only way there is no bind is if the housing is only attached in the middle and the axle ends can pivot back and forth or the arms are so long the arc is pretty much a straight line.
For that to happen the angle of the full swing needs to be no more than 10 degrees.
That might be the case already and if so it's all good.

Working adapting my power steering lines. The toyota steering box uses inverted flare fittings, but evidently the flare nuts are specific to toyota. Where I have it mounted, it's fairly close to the A/C compressor so I don't have room to make the bend with my normal tubing bender, plus room to pull the flare nut back far enough to get the flare on the tube.

The above quote was what I could get out of AI. It appears that will work, but I'm going to take everything down to the local hose builder and see if they can hook me up.

One side note, I'm not completely positive which port is the supply port. Both ports take a 10mm inverted flare, but one has the nut threaded at 17mm and the other at 16mm. Normally I would assume the bigger size is supply, but I've seen info that suggests it's the other way around. I'm going to try and have the hoses made in such a way that I can easily swap them if I get it backwards.

Looks like it's the fitting closer to the motor. Not sure if this is exactly the one you run.
