I really hope the chain doesn't fall out and hit me in the face.

Live Axle build.  The theory behind this is simple. 
Im having 4 bearings inside a tube, holding a jack shaft with various adaptors and spacers.

I have drawn over mandrel steel tubes with holding the bearings and i have an small tube holding the bearings to the outside where most of the load is. 

I chose ball bearings because they are recommended for higher rpm but the downfall of that is that they are recommend to take a radial load and not so much a trust load, which can lead to scoring of the bearing and premature wear.  I got one sealed bearing for the outside and an open bearing on the inside because i would like the keep the inside bearings greased by making a grease nipple inside tube.

Looking at the CAD model:

I have the purple flange as a spacer to bolt to the CV joint.  The bolt pattern is 4 X 100mm, for a Mazda Rx-7 or Miata, which I'm going with because the price was right on ebay.

The blue flange has the bolt pattern 6 X 5.25" for the sprocket and brakes from Hyperracing.com. 

The red flange is to bolt it to the inside of the engine mount, which is slotted to remove the chain if needed.  Also the inside slot is undersized to hold in the bearings from the axle.

Looks like a Tuba

Putting together the rear swing arm.  I'm really a novice when it comes to welding so the work is pretty so-so.  All that matters is that it's dimentionally correct and that it would hold up.  So cost of this part comes to:

Putting together the design for all the parts that im going to custom make.  I have pictures of other projects that I'm getting some example from.  I have a lot of ideas floating around, the more I get in to it.

I've also decided to keep updating the price of this whole project, just as a FYI for anyone interested in making their own.  Also all my CAD files are for everyone.  Shoot me an email if you want to use any of them.

Intake this!

Building an intake manifold, why? In case I decide to turbo it, I have something to hold the pressure.  Pretty simple to make: tubing + extruded aluminum mailbox = Surge Tank!

Project Gsxr-Cart

Craigslist: $200

Craigslist: $650

Getting started on a new project for the summer.  I want to build a mini sand rail, out of a GSXR-600 engine... possibly turbo.  Again, I'm going to buy everything as cheap as possible, and do as much as I can before buying parts.  The frame i got for really cheap, because the company, Redline, went out of business this year and I snatched up a frame.
