More rust removal
As the title says, more rust removal from inside the chassis spine this week so no pictures. Same technique as described in my previous post. I've probably still got a couple of sessions of this to go before I'm ready to weld the cover tabs in place.

Getting rid of the last of the rust
I've now got a couple of sessions of cleaning off the last of the rust. This is inside the chassis spine and concentrated on the lower panel...so the remainder of the original panel where I now have two covers.
No pictures this week as getting shots of rust in this area is difficult and not that interesting.
To get rid of the corrosion I'm using the trusty wire brush on an angel grinder which just about goes up inside the tunnel but is tricky to use as it can catch quite easily. I also have a small wire brush for use with an air drill to get into the bits not accessible with the angle grinder. Lastly I'm using an old screwdriver to clean the seam joints.
Once the loose rust is removed I give it all a blow through and wipe down. Next I use a product from POR 15 called Prep and Ready. It's a liquid that is sprayed onto the rusty areas. It eats the last of the rust away and etches the metal, leaving a zinc phostphate coating. This takes a while to do it's job and requires agitating with a brush every 30 minutes or so. It's good stuff!
Finally once any remnants of the Prep and Ready are rinsed away and the area dried thoroughly it's primed as I have done with the rest of the chassis spine.

Marking up for the cover tabs
This week I'm marking up in preparation to weld in the tabs that will hold the covers.
First up is to mark and drill the covers for the Camploc fasteners.
With this done I attached the tabs to the covers to find out where on the chassis spine they will finally be located.
This was then marked on the spine.
For the rear most cover, the back two tabs needed to be angled.
Final marking of the chassis spine for both covers.
Then the spine was drilled. I decided to use three plug welds per tab.
