CR Steering Box Project

[ArdenK]

We have one here in Durham, NC, called Tech Shop,

COOL !!!

I didn't know they were on the east coast! AWESOME !!!!

Now where can I get my hands on a CR box? the last one I saw was $1600 on ebay, I bid 1550, lol.

TY for the Info!

[ArdenK]

Bruce,

Get an estimate to have the regular gears made, I'd be interested in getting a couple sets. I think I know where I can get a CR box, the Big question is how much. If I remember correctly the guys box has a bad spot in it but that should be repairable in the CAD process or with modeling. I'll give him a call tomorrow.

[brucedemuro]

Exactly, its definitely repairable.

When I get the totals I'll let everybody know.

Cheers!

This is something that will get alot of interest once it gets fully moving, how many turns lock to lock is a QR box?

[JasonBird]

Im up for that as well. I will happily pay if someone can get a Normal and a CR box internals scanned. So four gears made in plastic. And I will pay the shipping to the UK.

Means I can start this with my project over here.

[brucedemuro]

Same thing here!

If anyone is willing to go and get them scanned I'll cover the expenses to do so and get them shipped!

[nbcbird]

Sort of a stupid question, are the RHD and LHD boxes the same (or are the internal gears reversed, so two different versions have to be made)?--Jim

[brucedemuro]

I'm almost certain that they're both the same...

[JasonBird]

If I can find a LHD box here in the uk in the next week I will rip it apart and have a look although I am sure some one on the board may have also hold the answer to this question.

Here's another place that might be worth a try: http://www.emachineshop.com. Email the CAD file and they will make the part for you. Haven't used them yet.

As bruce has mentioned a few times these parts should really be cast, hardened then ground down. Hence the need for a mold of some sort. That's where the 3d scanner comes in.

So for Bruce and I, is there any volunteers with access to such kit?

Jason, guys,

This afternoon I took a little time to get things started, I took one of my own Stock Steering Boxes and took it apart, contacted some of my friends and got in touch with the shop that will replicate the parts to get an estimate.

Here are the pics of the dissembled box (after a dishwasher über cleaning process)...

Next week I'll go and get them quoted...

Funny, I pulled a junker apart today, too.

I don't mean to pee in anyone's wheaties, but DAMN that is a complicated

shape for the screw... getting it right AND hard enough is not going to

be trivial.

'Hardened and ground' indeed.

Good luck- I hope you can get it to work...

Strangely, I *may* have access to a scanner and printer... at our company's technology center. I remember seeing the 3D printer there.

I don't know if I can get into the city next week to confirm if they have gotten the 3D scanner or not.

So I am not promising anything, but we are not out of options yet.
