Had to make way to pull tight the braid on the tube. Use a pull clamp with couple vice grips, it worked but need to be improved .
Tube is .266 and nib and center band is .328 so you don't have much left with braid pulled very tight and a coat or two of thin CA , blank is at .318 before casted in Aumlite clear. Another thing is the tube, even with braid pulled very tight the brass tube shows a little in the back round, that is why I was was looking for nickel tube, which I found from my good friend Warren White as he has some in his stash.
At first I tried to just use CA to coat the braid blank but results was not even and that is why I casted with alumlite clear.
