Bretsftw, how are you accomplishing that?? I would love to do that to mine.
This isnt guaranteed, its the first time im trying this out YMMV
1. Gather an old cereal box and cut up a strip into some small squares, bigger then the hole in the blade.
2. Somehow measure the size of the hole (For this I used one of the circle templates that are common at drafting stores) and draw that circle out on a square of cardboard, trim out.
3. Layer the cardboard together and glue. let it cure under some weight for best results. (the CC2 has about 4-5layer thickness i find)
4. After a day of curing it should be good to go, trim the rest of the circles. (Here i did the bulk cutting with some a nicely tuned ffg delica, then rounded out the edges with a dremel and fine grit sandpaper attachment)
5. Put the circle cutout inside the hole and add some modeling clay to completely fill the comet tail, make sure to leave one side flush with the blade (I found my old modeling clay used for a game im not gunna mention to try and save face. but the clay is called "green stuff" exactly like the old JB stick weld)
6. Let the clay cure for 24hrs minimum, or as packaging states.
7. Push the whole block out and toss the cardboard, its done its duty, then using a file or dremel carefully remove the access.
8. Using a dremel or file Double bevel all edges on the comet hole and the plug you've created
9. Mix up some JB weld and put it where youve bevelled the edges, Now you can do this one of two ways. 1. fill the whole thing in and let it cure. or 2. be paranoid and act as if this is your 1" plate 1F exam at the AWS. I prefer the latter, though I doubt the results will change to much.
10. It should leave you with a nice round hole and an uglier then all-hell plug but itll do the job. If you really want to make it purdy, sand it up to lets say 1000grit and take some silver paint to it, might blend in, if your willing to try your chemistry add some polish, I have no idea whether this will melt the whole thing or make it look nice, better do some testing prior.
Anywho Like i said im working on it not fiddling with a finished product. Currently on step 6, well see how this goes
To the OP, sorry for thread jacking
