Trans Protection and Rear Wing Chassis Mount

I am long overdue for an update so here goes. I have been slowly working on the rear car and putting together a solution to protect the transmission and also provide a rear wing mount.

These were the inspirations.

Welded some mounts to the rear chassis brace.

Set up the frame for this structure. I used clevis ends on the tubing ends to attach to the chassis. That way I can remove the whole structure if I need to pull the engine.

Fabricated some saddle gussets to reinforce the cross members.

I cut away a lot of the rear bumper. The plan is to replace the cutout with a black metal mesh and then just go with a pair of circular tail lights on the ends. The rear wing supports would then attach through there along with running the exhaust through the center.

I have a cross member that protects the transmission.

The whole thing can rotate up or be completely removed.



SIP – Protocol Overview, History & Basics

What is the SIP Protocol?
Definition: SIP, or session initiation protocol is a signaling protocol for IP-based telephony applications. A signaling protocol provides the control layer for communications such as the establishment and release of a voice call.

History of SIP
Previous signaling protocol such as SS7 were designed for circuit-switched networks. These networks use dedicated T1 channels for carrying telephony communications and signaling. With dedicated T1 channels, SS7 is able to provide high-quality voice communications, but at high cost due to the requirement of end-to-end dedicated channels. With the advent of IP and packet-based networks, telephony traffic could be routed more efficiently and cheaply. But this required a new packet-based signaling protocol to be developed. SIP was born. Initially designed for voice communications, today it can manage instant messaging, video conferencing, and file transfers.

How to access the ExtraHop REST API using Java

Although ExtraHop provides a powerful visualization system out of the box for viewing and analyzing your network traffic, you may need to retrieve your ExtraHop network data for integration into other systems. Perhaps you need device data for an overarching inventory management system. Or you may need specific application metrics for custom calculations involving other data sources. ExtraHop provides an extensive REST API for these purposes. It provides access to just about anything that you would want to know about your network. If you are looking to export a large amount of your network data in real-time, then you may want to opt for our Open Data Stream.

How We Log Exceptions in Production Java Application Servers

One of the challenges of Java web application server development is catching and analyzing exceptions from your web application after deployment into a production environment. Whether your web application is deployed on Tomcat, Apache Geronimo, Glassfish or JBoss/Wildfly, analyzing exceptions involves digging through application server logs to isolate an issue.

More Panels, Tabs, and Rivnuts

I think I am overdue for an update!

My goal is to rivnut most of the panels. This requires fabricating and welding on a bunch of tabs.

Front underbody:

Side body panels (with CF splitters):

I picked up a JD2 M3 tube bender for building my own rear chassis wing mount/transmission protection.

Digging the open rear end and the rear attached wing supports; wonder if anyone has tried this.

Tube Bender

Got my new JD2 Model 3 Tube Bender in preparation for building the transmission protection/chassis mount wing. I ordered a 1″ die. Most use concrete anchors to fix the pedestal to the garage floor. But I want a temporary location, so decided to use the lift. I fabricated a mount for the lift. Then tube bender pedestal bolts to it.imageWelded up the mount frame.

Front Firewall and Intrusion Panels

Finished most of the front firewall, intrusion panels, and interior panels. Rather than using rivets and drilling into the chassis tubes, I ended up welding on a bunch of tabs and using 1/4 and 10-32 rivnuts.

For the intrusion panels, I used 6061-T6 1/8″. The interior panels were actually the FFR exteriors, but I trimmed them for the interior. All the panels are then fastened using 1″ counter sunk spacers.

Also cut away the door mounts.



Bye Bye STI

Off to a new home in Oregon…

Shafted

Man, you guys make it sound so easy! Tried the hose clamp method without any luck. I am using the STI rear shaft. The groove in the FFR shaft is deeper and looks wider. I think that makes easier. Yet another STI issue it seems.
