........" why me in my workshop with simple tools regularly finds simpler ways to make this stuff." 'cause your good!!!!!!

Rob ......... the plasma reduced the heat signature but nonetheless when the top and bottom cuts were done by hand there was the Odd Boing as some tension released...... and the cut out piece had a definite twist in it.

Not sure what kind of steel alloy they used when fabricating them but it is not easy stuff to weld with a Mig......almost like zinc coated angle iron used in hydro towers.

They do seem to be an odd mix of metal. Whether that is the result of being made in Chine using recycled Hondas, or intentionally made that way to better resist saltwater is the question.

I had the job to put a window in a sea can, for a neighbour, that is being used as a mechanical room at a grain elevator. There is a special alloy used in the construction that is corrosion resistant. I can't recall what it is called but there was a post on the unit saying to repair with the named metal. I used a angle grinder and disc to cut the opening and bolted a metal frame onto the side wall.

Door is finished..... now toooooo heavy for a one man install.... in fact I think we will use the bucket on the tractor to raise it in place and slip in the hinge pins.

Heavy door so we installed 5 HD hinge...... had a bucket full of them.

Frame is tacked in place and will need a continuous bead of weld to make sure it does not leak.

Art work below.....

Looks good. As for doing a full bead weld I'd skip that. Just use that spray sealer for sealing screened for bottomed boats. Surly it should work for sealing some seams that aren't in a sea salt sea environment. Now tell me how many "s" I've used in this post.

Hi Gord

Yes I have seen a similar sticker inside the containers specifying that a certain kind of steel needed to be used for repairs.

Jordan

With the many freeze/thaw cycles in Ottawa I want to make sure no water infiltrates around the frame. Maybe just one welded on one side then caulked will suffice.

Now I just need to salvage the special hinge brackets from the cab 12 that will allow adjustable/folding mirror arms so I can drive in the sea can without having to unbolt the cast rigid mirror arms.

A final coat of paint then voila!!!!!

......and maybe my pictures will come through this time

With the house generator hooked up to the MIller 210 It was a more pleasant than using the 110V baby mig I used for the tacking.

Even with the shielding gas turned up for outside welding the steel alloy of the container is a bitch to work with. As I did the outside seam a lot of smoke was generated..... turns out there was water already trapped between the flanges.... and what I though was paint burning off was steam..... and the water made the spattering worst. I blew most of it with the air line and there was enough to form a small puddle on the floor inside.

So decided to do a continuous weld seam on the outside......(sorry Jordan) and will caulk the seam for good measure. The inside got a few more robust tacks for my peace of mind. Noticed that the cold steel of the square tubing is already flash rusting......while the container steel that was ground of any paint for welding still looks shiny!!!!!

Hopefully the door will go on later this week.

Sea cans use Cor-Ten steel, also known as weathering steel. It combines the properties of corrosion resistance and tensile strength. The idea behind this is a steel that requires little to no paint and will withstand many years of outdoor usage.
It is difficult to weld using regular weld materials due to the specific alloys used in it. The alloy materials include copper, nickel and chromium. Suggestions for non structural welds include the common E7018 electrode.

Well done guys. That should make it a lot more functional.

First, my apologies for not posting more frequent updates on what the barn people have been doing. I will try to catch up.
Recently the barn team went on a parts recovery roadtrip. Not a crosscountry or crossborder trip but with some interesting results. Rob got some interesting parts for the M-37 series and I ended up with most of the CMP Cab 13 parts. 2 seats of a pattern I didn't recognize, a cab back panel in fairly good shape, a cab floor of a pattern that I had not seen before (but should have known would exist, a cab nose in less battered than average condition, a couple of 20" rims, PTO tire air compressor and transmission and transfer case (also of a pattern I had not seen before). We were told the CMP parts had all come from a C60L operated by the RCAF. This is consistent with the parts provided and the yellow paint on them that didn't appear to be a recent respray.
