AR-51 build
« on: May 30, 2015, 03:25:42 PM »
Well, The title says it all.  I really miss having a sandrail.  But I don't miss how wide my old car was.  So after a lot of thought, I went ahead and got plans to build an AR-51.  It is basically a modified and refined version of the piranha.  I sold by dirtbike last summer because it was killing my knees.  I guess with age, comes the cage.

Here is the start of the chassis.  I did most of my cutting and fab work on the chassis at work, on the weekends.

Here is the bottom portion of the chassis.  I love me an acorn table...
 



Once the base was tacked together, I tacked up the nose section.  Im pretty lucky to have a water jet available...



Next up was the rear end.  It is made up of a few plates, and some tube....and lots of clamps holding it together.

Once all tacked up, it was time to start making something that resembles a sand rail.

Just so happens, I had a table there just wide enough to build most of the chassis on..






When I started the mid rails, out came the string line and the square.  It went together really well.

Well, after I got this far, I forgot to take pictures as the chassis was going together, and this was the outcome.  LOL



Kinda looks like a UFO from the back.  LOL

From this point, I brought the chassis home, and it sat in the garage for a while.  In the meantime, I kept cutting plate work out, parts collecting ect.

I made up the jig plate for the arms and got them built as well.  The parts just fit how they were designed to fit.  Once I had all the arms built, I fit them to the car, along with the steering rack, and tie rods.




Just a close-up of the welds on the rear uprights.


And a very loose mock up.

Next up, welding up the rear spool carrier.



And some more mocking up.  Bolted on the rear caliper mount.




And a big ole rotor


and a big ole sprocket


All bolted together, just to take it apart to fit it in place..  DOH!!

The freaking brake was down at work, so I bent the sprocket and rotor skid plate old school style.

Laid out my lines, and cut the plate with a cut-off wheel, a bent the plate, and welded them up.  Worked grrrreat!





A little test fit.


And smoked together.

Nice work but in the pic of  sprocket mounted it looks like a chain won't fit on right next to bulk head plate

But no doubt it's the view

It does look that way, but there is plenty of clearance between the bulkhead and the sprocket.  Poopy picture.  I gotta hire a better photographer.  LOL

The front hubs, and front uprights came from RickS.  Really nice TIG welds.

I really like how high in the chassis the radiator is.  And there really isn't anywhere else for it.  LOL  It has a good size oil cooler as well.

Here is a better shot of the sprocket clearance, and the rear a-arms.

And a couple shots of the car as it sits.  Next week will will be fabricating the fuel cell, and the mounts for the tank.  Also, a few tabs for the rear skid plate.  I think after that, will be sheet metal and some paint.  As for a motor, I dint have one yet, but I am leaning toward a GSXR 1000, or an R-1. 

In the shock department, I think I will go with the King coil-overs with remote reservoir, with compression clickers.

What do yall think?

Way to post a build thread deranged.  Love the build. 

If I believe I cannot do something it makes me incapable of doing it. But when I believe that I can, then I acquire the ability to do it , even if I didn't have it at the beginning.

Damn nice. I take it that you have done this before.
