Clean inside of the frame?

[gfleduc]

Anyone have a nifty or slick way to clean the inside of the frame?

On my '65 - I am thinking of trying to drag a wire brush or something, down inside it (front to rear). I was hoping someone may have had a cleaver method.

TIA

all I did was take off the two bumpers and use a 12 foot piece of 3/8 steel line coupled to my pressure washer and blew it out from one end to the other. after it dried out I used the same piece of steel line coupled onto my corrosion proofing gun and blew in a coating.

Copy that

What did you use for the corrosion proofing?

thank-you

I had bought one of those cheep pneumatic undercoating guns from NAPA , used 3/8 brake line and brass unions to connect the 12 foot line to it and I threaded the tip to fit the spray nozzle . made a 12 foot spry gun inserted it all the way, pulled the triger and walk backwards pulling the spraying line out. Worked perfect.

I used an aviation corrosion proofing , Dinatrol AV 8 now called ARDROX AV8 is a wax based liquid that creeps through the seems and after a couple days dries up to a wax coating that can be washed off with paint thinners or varsol. goes over rusted surfaces well and seals them from continuing to rust

Thank you for the information!
I expect I will follow your lead ...

Can we see your setup/nozzle. I would like to copy what you did.

I dont have it any more, it was a one time use thing and it was tossed 4 years ago.

Eastwood has an aerosol rattle can rust reformulator product with a hose and nozzle. I used it to coat the inside of the rockers front to back. Worked great. $15.00 a can. Im going to use it for the door hinge jams when I get to that point in the project. Im fortunate that I have an Eastwood store nearby...A bit expensive but they usually have the right tools for the job...

Think about it....
If there is no repairable rust damage along the out side if the formed box tube frame rials by now.
You will more than likely be taking a dirt Nap.
Before you will ever have to visit whats left of this vans body with a welding machine.....

Initially at first had a hard time pushing a snake though the frame (the plumbing snake was no help), my tape measure made it!

Once I got the tape through I pull a steel cable back through. Now I go back & forth with that...



updated - I just ran an air hose through it - lots of sand, some acorn shells & about a baseball's worth of insulation (mice I presume).

Are those mud wasp nests. they kinda look like Toll house cookies and someone sucked out the chocolate chips!

[gfleduc]

Nice aren't they, almost like rocks.

[m1dadio]

better to have all that moister holding crap out of there.

Agree - I made multiple passes with the air hose. I would like to run something abrasive through the rail now - thinking about a 3" flex honing tool - rigging up a rotating long reach item if my currant contemplation.

I plan to run some Alspho - then corrosion protection as you did...

[gfleduc]

I used MIDOs idea for a template & did the following:

a) I ran a steel cable through the rail for pull from the front / /pull from the rear.

b) Tapped a Ø 1/4" hose fitted to my air compressor. Cycled it through by pulling the hose back & forth to clear out debris. I got acorns, mud wasps nests, grit from sandblaster & a baseball's worth of insulation to blow out.

c) Same 1/4" hose attached - I made a bullet shaped nozzle fitted to one end & hooked an air gun with reservoir on the other end (Truck bed liner sprayer; I think a sandblaster gun would work also) . Sprayed ALSPHO through it (back & forth about three times). Let it sit for a while - hour or two. .

d) Removed the nozzle and spray gun. Then again blew air though the rail back & forth to clear our excess ALSPHO. Removed hose & cable.

e) Sprayed Cor-Ban 22 through the frame using the 4' nozzle / tube (see attached) that can be ordered with the Cor-Ban.

What about using a chimney cleaning brush with the typical extention rods or a cable to scrub it out? I seem to recall they Make small diameter ones for pellet stove flues.

I used an endoscope camera to checkout the space between the nose of my van and the interior wall. It was $36 on Amazon. https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

It Bluetoothed to my phone. Found lots of pine needles and dirt/dust. To clean it out I put a spray nossle on the end of a garden hose, put it in the channel via the hinged air vent inside the cab on the firewall, then turned it on and slid it back and forth. Worked great. Got out much more than I thought it would.

Also used the endoscope to view inside my cargo door to figure out and help me take apart the door latch and rods. I could hold the camera with one hand and a tool in the other to then watch my phone screen and manipulate things inside the door. Real helpful.
