HICAS Lock bar

[Race__24]

Hi guys,

just thought I'd show off the HICAS lock Kit I Designed and manufactured for my R33. I'm pretty happy with how it turned out.

It replaces the rack/motor, rose joints attach the new shafts. The other end of the shafts screw into the existing outer joints. I could have got away with screw cutting the original shafts but I wanted the be able to swap back if need be.

Tell us what you think

that is neat. one off?

I'm tempted to make a couple more but i want to run this one for a while just to make sure it'll do the job. Then after that i'll look at getting a couple made for people.

[Nozila]

if you do decide to make more please inform us as id like one of these.

[Race__24]

Yeah, no worries. I should have it on later this week.

looks good, its exactly the same design/style as i used to make them when i had the time except i used mild steel

Nice piece of work. Looks like it's well designed. What grade of ally billet and what rod material are you using?

I'd recommend rotating the rose joints so the grease nipples can be accessed on the car though.

I've also seen one that uses longer rods with the rose joints directly bolted to the subframe. Might save some machining and material.

I can't remember what exact grade the aluminium was, i know it was a structual grade tho. The rods are M238 tool steel(P20).

I was thinking of making longer rods going directly to the subframe but i thought that i'd replicate the geometry just in case it was critical. Having said that the difference in the angles envolved probably wouldn't be too great anyway.

A good high toughness steel like that should be fine to run the full length. The loads ar not great and you'll save a bucket on the ally.

Interesting choice of steel though. Used in the plastic moulding industry a bit.

[Race__24]

I'm a toolmaker by trade, but i specialize in CNC machining, CAD modelling of electrodes and EDM operations. That explains the steel. Figured i'd go for P20 as it's pretty much indestructable

Actually the aluminium only cost me around $35, through work tho. The full length rods would still be cheaper but they wouldn't look so fancy!

if u make a few put me down for one as my hicas is on the fritz and lock kit would be the solvent i need keep me in touch with what ya do cheers

Fitted my lock yesturday,

had to make a slight adjustment as it just fowled on the subframe, nothing major tho.

My mate and i wheel aligned it by eye and got it within 1mm each side! How ARSEY is that!!!

An easy $50 for the bloke that wheel aligned it, although my frount end was out by more.

Everything is working good so far
