Thread: Lifted P38 on air - questions

Thanks Paul. Looks like I'll have a good bit of experimenting and playing round them to find what to wind the values out to. Main thing I'm aiming at is to have the sensors near, but not at, their value before faults when the shocks max out. Good news is it sounds like the faults happen well before making the sensors physically max out, so gives some good warning before breaking. If faults keep happening unexpectedly then I guess I adjust as necessary.

As far as sensors go I extended the originals by way of cutting in half and fitting to a s/steel turnbuckle type centre so that they are very adjustable in situ so getting the values you require is quite simple. see attached pic.
I also have GenIII and 33" KM2's for your info.

Martin - do you have final adjusted lengths of the lower arms, front and rear? To give me an idea of the extension amount involved. I have a selection of rod ends and ball joints from midwest controls (Home - Midwest Control Products Corp.) sitting in the garage at home and wanted to check I'm in the ballpark for length.

Cheers - Sean.

Keith and PBrown - would you let me know the o.d. and i.d. of the disc used for the 2" spacers - assume 5mm thick is enough. And the angle used for the rear. Wanna get some laser cut for welding up at home.

4mm steel, if you go thicker you won't be able to put the "r" clip into the bag piston.

It's easier to explain via the drawings, the rear bags especially as they sit 180 degrees to each other so you need to get the direction of the piston pin right when welding.

Peter has the latest drawings (minor updates made after mine were cut). I'm sure he would be able to assist in your quest!

Mine were laser cut and came out a touch sloppy but still good enough to do the job.

Cheers

I'll upload the drawings once I'm back in oz in august. They are on my work laptop and need a little revising before releasing to the forum.

But I can tell you that we made the hole diameter 37mm but the pin of the bags are actually 35mm diameter. The slack should sorta work in out favour once the final design is finished. Off memory the flat spot on the D for the hole was made to be 30mm (28mm on the bag). The rear spacers for mine had 32mm/12mm taper for the uprights (middle 22mm with 20mm difference between for and aft) , with the front a flat 22mm (total height 30mm when you add the two thicknesses of the top and bottom plates) . Keith's were 20mm higher all round. Diameter of top and bottom plates was 125mm.

Hope that helps a little. Bit hard to describe in words.

If you can wait a month or so I'm back in oz and Keith or myself have actually installed them, I/we will be happy to share.

Well said Peter!

Much appreciated guys. I've just ordered the discs.

We would have offered the auto cad files sooner, however we were hoping to put some real world testing behind the designs prior to letting them out.

More a "if someone hurts themselves using our design" thing. That said - these are not engineered yet, nor are we a business and as such we claim no responsibility for anything that may/may not happen as a result of the design.

If you can hold off a month or two ill have mine fitted and tested, as will Peter no doubt, We can then advise on what worked and what didn't work on the kit.
