I used a 5’ section

3 inch pellet pipe or B-vent will have a 3 inch inner wall and a 3.5" diameter outer wall. Pellet pipe has a stainless inner pipe, B-vent has an aluminum inner pipe. Both can be bought off the shelf at Home Depot.

Thanks in advance!

Oops. I didn't mind your asking, I was just unaware since I had not revisited the thread. But I think you have your answer.

Also, as an update, I sure hope mine holds up, because now it is blocked in pretty well by the new cross-bracing.

For the next guy that needs another way. Here is what I am gonna do with my 72 Deluxe. Maybe I should say gonna TRY to do.

I had to cut the original tube flush with the large lateral beam that it runs thru. I could, I suppose dig out the remainder of that tube and make the ID a bit bigger. For now I am working with 2-5/8" ID on the rear and 2-9/16" on the front.

REAR

FRONT

Here is my plan using 2-1/2" OD exhaust stuff from Advance Auto. The btm of the pic below is the front. I figure to wedge the coupler piece in the brace then slip the Flex pipe over that. However, the flex pipe will fit snuggly in the hole without a coupler piece. In the rear, I will use a piece of cut tail pipe and slip the flex tube over it.

It is all Nickson Brand pipe. THe pipe pic is flipped with the right being the pipe I will cut for the rear. Just need about 6" of that 18" piece. Wish me luck.

Lastly, I will need seal up the joints, insulate it and support it.

I did not cut out my Y. Only straight pieces.

Here is my fix:

Stainless tubing with silicone couplers all from Amazon. Super cheap and easy. Not going anywhere anytime soon.

Looks good. My problem is that I cut the tube flush with the cross member, so I need some way to attach. Going to have to insert a pipe. Maybe seal it and tek screw it thru the cross member. Just have the parts, but have only dry fit everything together. Stainless seems like a good way to go. I am gonna have to paint my exhaust pipe parts.

re-energizing this post,

I have the paper tube for the center heating.

Thinking of just wrapping the paper tube with asbestos cloth, used for welding. Securing ends with fiberglass ties. material does get wetted, but it dries. Not sure if it does a wet through, will have to check that out.

I see someone has used aluminized fiberglass ( aluminum with fiberglass backing) - ( but it looks thin) with ceramic wool

( about 3/4 down)

any comments for this approach. Wanting to insulate my heating tubes a bit.

Thanks

I am using the pellet stove vent for the main pipe and flexible ducting from Lowe’s. I also found a Y vent piece I found on Amazon. Also exhaust connectors from Autozone. To fit pieces together, I either used an exhaust pipe expander or stretched the metal with a hammer and dolly.

I am also using a bilge blower to boost the airflow except it will be connected via the Y piece which fits in the same location as the long gone diverter thing. The blower will draw air from the floor vent behind the walk through.

That is a nice setup for sure.

I am going with wrapping the tube with two layers of fiberglass blanket used for welding, then wrapping that with vinyl wrap to make it water proof.
Pic.s later.

Sounds exotic!, I went the simple route with the foil backed bubble wrap for water heaters and the foil tape that was beside it on the shelf at Home depot, spooged the sh*t out of it with rubberized undercoating afterwards, 10-15 years so far with no issues. YMMV.

The dream would be to have air inlets from inside the cabin and being force blown back into the heater boxes.

Why the cross bracing?

This isn't the best picture of what I want to show, but this is my center duct, beta addition. The bilge fan is now gone, and now sits in the flexible duct near the front torsion bars, but the rest of the center tube is the same. It is a piece of fairly thin wall stove pipe with the crimp for the seam snipped off. I just fit the split pipe over the two "nipples" on either end of the span, use some band clamps to draw it tight and then use pop rivets to hold the seam together. I then wrapped the pipe with a couple of layer of foam insulation followed by covering the whole shebang with a split piece of thin wall pvc drain pipe held on by band clamps. This was done about 14 years ago and is still working well.

Any difference moving the bilge fan forward?

I made lots of changes to the stock setup at that time. Think I get about 3-4 times flow through the heater boxes as a stock setup and its noticeably hotter. Its all layed out in the Blumaxx thread.
