This "big hat" is from a 1930s Canadian Coleman 228B. As these are hard to find in Australia, I decided to repair this one so that it would be usable on a "user" lantern until another turned up somewhere. Given John's (@presscall) recent about construction a Tilley hood (Constructing a hood for a Tilley X359), I thought I'd post these photos of my resurrection of a Coleman ventilator. As it came Rust had eaten large parts of the central perforated cylinder piece. The repair I removed the rusted part from the refector section and the top cap. I then cleaned up and treated the rust on the remaining enamelled parts. I had a piece from a sheet of perforated stainless steel cut 42mm X 237mm. I annealed it, then using brute force by hand, a rubber mallet, and a curved steel block, I formed a cylinder that I then sil-brazed at the seam. Note the brass strip (far side) that was used to sil-braze the seam of the perforated stainless steel cylinder. The stainless steel cylinder was then carefully fitted over the remnants of the remaining cylinder and forced into a friction fit on the reflector part of the ventilator. Note: My intention was, that if the perforated stainless steel cylinder did not stay in place, I would devise a way to permanently affix it to the reflector. This was not required as the two parts have not loosened even after some use. I did not intent to affix the top cap to the cylinder. I've used this a fair few times over the last few weeks and its working well! Cheers Tony
Excellent work Tony! I’ve been away at the Festival of Light, so the Tilley hood project is still a work in progress. John
