Spindle question
 

Anyone happen to know the angles of the strut mount on the spindle?

Re: Spindle question
 

I have the blueprints somewhere, ill dig them out tonight

Re: Spindle question
 

The steering angle inclination is aprox 13*. It could be fudged a little more or less based on slop of the angle between the strut and spindle bolts when tightened.

Dean, the degree symbol is:

Hold down the Alt key, type 0176 on the num pad with NumLock on, and let go of the Alt key. ;)

Works in ANY program, because it's an operating system function, not an app one.

That's on Windows and *x. Not sure about Scrapple. I avoid the Empire. I may just be a blockade runner, but I can outrun any Imperial cruiser.

Just for fun, try other combinations after the 0.

Enjoy.

Re: Spindle question
 

If deans number wasn't what you were looking for, the mount on the spindle is angled on 2 axis. From vertical off the snout, its 16.5171 degrees inboard and what appears to be 50 degrees of rotation from vertical.

thanks!

wow.. my estimation was close. I estimated 45 and 12.

Re: Spindle question
 

I actually had no clue on the spindle numbers itself. Impressive info. Rarely do I see anyone come up with such detailed specs....Especially when I've ever ask on a board for help.

Re: Spindle question
 

I think it was Costas on FRRAX that had the blueprint.

Re: Spindle question
 

It was. He was selling prints 2 years ago instead of scanning into a pdf.

Try fabricating a steel prototype spindle that would accept a 4th gen hub. This would be far easier and safer direction to go.

Once you cut and alter and cut and alter ,etc etc, etc.....you can fine tune the steering arm and overall specs of the spindle then pinpoint the finished product for possible billet machined piece out of 7075.

Then fab it into a drop spindle application.

This would sell like hotcakes.

If I had time and the machinery I would be working on this as well as a few other goodies I have ideas on.

Re: Spindle question
 

A $$$ piece for 3rd gens sell like hotcakes? I'm not sure the market is there yet. it's long been a problem with 3rd gen products, if you put any real $ into them it's very hard to get the typical 20something broke 3rd gen owner to get off their wallet and spend money on them. It seems like most of us that have been around them long enough to be nearly 2x that age and still tinkering with them are more likely to build our own then spend $$$.

Re: Spindle question
 

true however when it comes to something like a spindle that is impractical to fab up for a one off unless you work or own a machine shop. I would spend to buy them the question is price point... My guess is probably $400-500 is too end of what they could sell at. Question is can it be made for that....

Re: Spindle question
 

Yup, that's where I got my copies.

Re: Spindle question
 

Any chance on getting a copy of this drawing?

Re: Spindle question
 

I paid more like $700+ for the RR Racecraft drop spindles. And they make spindles for multiple applications. They are not a one-off shop.

To match their quality in a less experienced shop, would cost more. I won't even mention liability.

Re: Spindle question
 

My line of thinking is for a fabricated steel spindle that the separate pieces would have 'mortise and tenon' joints that would then be stick welded to structural specifications. More surface area and more safety if a weld did crack.

The front face would be up to half inch thick (a tad bit overkill at this point). The strut mount would be the full 33mm thickness.

The design right now is a 2" drop.

Re: Spindle question
 

Roughly where I'm at now.

Re: Spindle question
 

Just curious why you are going with a sealed bearing hub rather than the "snout" like stock spindles?

Looks like you are doing good work.

Re: Spindle question
 

I want the wheel speed sensor, ease of replacement and such, use of modern brakes, etc. Plus, creating a correct press in portion is a hassle i dont want..haha.

I need to refine the strut mount portion and move it a over a touch, finish the steering arm, etc.

Re: Spindle question
 

I figured it was for the use of the speed sensor. I don't know what it has to do with the use of modern brakes though. Wouldn't adapters for the caliper mount take care of that, just like the standard spindles?

Re: Spindle question
 

I can also design it so I dont need an adapter.

Re: Spindle question
 

any recommendations for steel to use? I would LIKE to stay away from chromoly

Re: Spindle question
 

If it were me, my go to would be 4140 or 4340. Cheap, strong, plentiful and easy to machine.
