33 Coupe Interior 41        11/20/04

This is how I plan to take apart the cage. I made six of these couplers that will enable me to join two pieces of tubing together and still have it as strong or stronger than the tube. These are made out of the same material as the cage is (4130 Chromemoly) and with the use of a clevis pin, I'm able to pull a pin and separate the two pieces. 
 

 

 

In this shot your looking at the ends that will get inserted into the tube and then gets welded on. The area of contact inside the tube is 1/2" and then the shoulder of the coupler buts up against the end of the tube. The clevis pin diameter is 3/8" and is made out of 316 stainless. 
 

 

 

Here you can see how the assembly will go together. Now these are just some scrap pieces of tubing to show how the coupler will work. Notice the hole in the clevis pin. To keep the clevis pin from falling out, I'm using a 1/8" roll pin that will go through the coupler and pin to keep it in place. 
 

 

 

This is what it will look like once the coupler is in place. The length of the coupler is 1.100" which is also how much the tube will have to be shortened to maintain the same length once it's installed. I rounded the end of the clevis pin so that it would match the coupler once it was in.
