Who has ever said, "If you want something done right..."
For all of those people who want it all in one bar, I am posting my method for building your own 5Line bar with Cam Cleat for on the fly adjustment. The final bar is clean and simple and allows for multiple safety connection points.
Disclaimer: Kiteboarding is a dangerous sport. Any changes or modifications you make to your equipment you do so with the knowledge that it is at your own risk. Safety is first and foremost about using sound judgment. If you don't understand the changes you are making, use good judgemnt and leave it unchanged. This post is considered a guideline, each circumstance is differnet and may require additonal modifications. Use these suggestions at your own risk. You have been warned!
Having said that I think these changes have provided me with more safety options and better mangeability of my 5th line tension. Personally this has allowed me to return safely to land when the wind picked up and I was flying in overpowered conditions. No safety is 100% safe however, and accidents can still happen. I have used the 5th line safety several times to avoid potentially dangerous situations successfully. However, twists in the center lines can reduce the effectiveness of the 5th line safety so be careful when doing tricks and kiteloops to reverese the direction too. More than 5 twists may cause too much friction for the line to slide properly.
What You Will Need:
ClamCleat CL203 Junior W/Fairlead ~ $5
2 X Stainless Steel Countersunk Machine screws No. 10 X 3/4"(or more if your strap is thicker or double layered) ~$1.50
It is good to buy a couple lengths of screws, it is easier than cutting them to fit with the dremel and doesn't cost much.
4 X 10 Stainless steel washers
Autolocking (plastic ring) Stainless Steel Nuts to match (No. 10) ~$1
Slingshot surefire Leader Set (Optional but adds two safety options - Highly Recommended) ~$30
3 X 3/4" stainless Steel rings ~$10
Floats (Optional) ~$5
3 X 5M Leader Line with Loops in each end (Can make loops yourself with a little time and patience) ~$15
Airrush Chicken Loop and Line W/safety (Has a Ring on the collar which is where the 5th line anchors) ~$20
Carbon Bar of desired width with a large center hole ~$50
Slingshot Surefire Leash w/safety (Or equivalent leash) ~$25
Sheeting Strap (Must be Webbing) ~$10
Other Needed Items:
No 10 X 2" self tapping machine screw (Does Not need to be Stainless Steel, used to make holdes in webbing)
Lighter or other heat source (torch, fire, stove burner)
Rubber handled pliers (For holding above screw while heating it)
A Clamp or vice is helpful but not necessary
BAR Cost:
~$175 (You might save money if you find the items on sale or start with a ready made bar and just add the 5th line part.
Add Lines:
5 Line Set (I used 19M K.I.T.E.S. Lines for my small bar and 25M on my bigger bar) ~$75 (check Ebay)
Total cost:
$250 (this can vary a bit if you find the items on sale)
5th Line Cam Cleat Setup:

1. Lay the sheeting strap out on the clean basement floor or anchor it in the vice (Do not damage the webbing)

2. Mark the spot for the Top Screw (Make it in the middle with sufficient distance from the end to avoid pulling out). Grab the Screw with the Rubber handled pliers and apply the heat source until the screw is glowing red.
3. While holding the opposite end of the strap, Quickly and carefully send the screw through the webbing near the center of the strap so the washers won't interefere with Trim Strap operation.

Note: Be sure to melt the edges of the hole sufficiently to avoid fray.
4. Place one washer on top and the other on the bottom and secure the Clamcleat with the fairlead closer toward the kite. Do not fully tighten the screw yet.
5. Use the screw (Not hot yet) to mark the next hole (hold strap snug and push through clamcleat mounting hole into webbing until visibly marked)
6. Rotate Camcleat 180 degrees (to avoid melting it)

7. Heat and make second hole in webbing.
8. Rotate camcleat and secure with second stainless screw.

9. Lock 5th line to 5th line leader by looping through and running down the line.
10. Run leader through camcleat, bar, and Chicken Loop anchor point. Larkshead to Stainless Steel ring.

Note: I keep a leader extension I can attach at the kite side because my BFKs have the ASS. I tie knots at 2" or 3" intervals for the last meter so I can customize it for each kite.
Finsihed Bar (No Lines Attached):

Surefire Leader Setup:
1. Attach Floats to Steering line leaders close to bar. Add plastic washers and tie not to hold in place.
2. Make a loop in the leader lines as close to the end of the floats as possible. (Make it just big enough to fit over the stainless steel ring)
3. Larks head the leaders to the stainless ring.
3. attach the hanldes to the Surefire leaders. Loop and lock the appropriate steering lines to the Surefire Leaders (Based on color)
4. Run the steering line through the correct ring
5. Fold the supplied center line and cut in half. Tie knots at 2 inch intervals and add to your existing Center lines at the bar end. (allows adjusting lines easily to compensate for the longer steering lines)
6. In Light wind hook up your kite and find the right knots on the center line (mark or make a mental note).
