Well, new suspension on the way. Given the total ineptitude of UK suppliers, I have some being shipped from Oz by Chris Blakemore at FNB. Full EFS set up with a 4" lift rated to take all my kit. Absolute pleasure to deal with. UK suppliers should be hanging their heads in shame frankly.
In anticipation of this, I started making the adjustable panhard rods. Yes yes I could buy them but given the cost and frankly what little they need to do, I figured I'd save a heap. Follow me into the man cave ..
Did make a start the other weekend but scrapped that lot and started again today.
Chopped a spare PH rod in the saw. Measured up around 26 mm.
It's seamed tube so I needed to bore that out to make it lovely and smooth ready for threading.
I threaded the RH tube first. 26mm 3.0 pitch. I measured it before cutting so that the short end would go through the chuck from the head end of the lathe, and used a fixed steady to prevent deflection whilst cutting.
Then I cut the bottle screw for the short end
Pretty simple. 3.0 is a bit of an ugly thread though. 2.5 or 2.75 might have been better.
Threading the inside of the long half (?) was easy enough. But setting up to cut the left hand thread on the bottle screw took a little fiddling.
Both ends threaded. Just need to add a little finesse to the central section on the miller so I can turn it with a BF spanner.
It all screwed together very well indeed. I took the lazy option to start cleaning the arm up in the lathe whilst I was about it.
Amazingly when I popped it in the lathe and measured the run out I got a total of 3 thou. Holy crap. That'll do for me.
Engagement of the threads at each end is 85mm. I think that given the typical extension following a lift is only about 1/2 an inch, this will be plenty. I may actually have to short the arm once I get the springs on. I may have made it too long to kick off with. But that's a five minute job. I cut a piece out of the arm to begin with to allow for the central section of the screw.
I then made up a couple of 26mm left and right locking nuts. Once locked off there is no detectable wobble or anything in the rod. I figure it's job, jobbed. The front one next. I shall over-sleeve that I think as it's solid.
So there we go.
