Welcome Edgar, Nice post. I'll just cross reference this here as an fyi. As much as the viability of your copper spreader is of interest and it is, I join curiousity and will like to hear back after a season of use that all is well (or not). Myself, fwiw I'd go with brass anyway. Copper bottom pans have me thinking yours should work fine. Years ago I was able to use the tow ball and large socket method (in link), the credit goes to Sam for that and btw he suggests option of just a ball peen hammer as well in his closing comment. thanks omc
I like the idea of making things. I roast coffee, bake wild sourdough bread, make my own seitan, etc. But I think with the availability of an original part for sale, I would go that way. But, YMMV. Ken in NC
Cottage-Hill-Bill: Of all the hobbies that I have....to date, I have never needed a jeweler's or a coping saw. Now that doesn't mean that I will not need one next week, but not yet. I have often thought that I needed one and each time I have found a solution to cut with something that I had on hand. I will keep it in mind thank you. I am not sure that I could cut a very smooth line with a coping saw that would save me any filing time. I could not possible show all my work in the pictorial above but I am pretty handy with that little pneumatic cut-off wheel. I just finished a pictorial on the Sniper Forums using my cut-off wheel converting an ADL to BDL, using the ADL magazine. Any way, thanks for the advice, Ill keep it in mind, but that only thing that I can think of that I cannot cut ever so gently with that cut off wheel...would be something where I would have to insert the coping saw blade through a hole to begin cutting. Like removing the back ground from the inside of a coin to use for a medallion. I still would need some MICRO files for finishing.
OMC...thanks, I really didn't know what I was doing when trying to "cup" the flame spreader. It wasn't until after I found an appropriate sized socket that I realized that I should have used the socket in the first place to "cup" the flame spreader. It would have worked more uniformly. Your Idea to use a Tow Ball and a socket is another great idea that I will remember if and when I ever need to "cup form" something else. THANKS !
