turns out one of the half dozen extra tc tangs i have pulls it much closer to center,, (those cast parts vary quite a bit between lots or vendors!). it still has .005 gap between tang and breech plug,, which is nothing compared to the one that came on it,, & will require very little work to get it dead nuts flush. After i get a white lightning liner in it the flash hole will much better suit me..
The reason i asked for smith suggestions is i've had 3 knee replacements & a lower spine compression that makes standing at lathe or mill uncomfortable. i'd rather pay somebody else to do it these days. I'm not a "shade tree" smith like some of the "trolls" professing suggestions, i've done gun work for 30+ yrs now & shot for more than 50 & didn't ask for suggestions on how to fix it, i asked for the name of someone else to send it to... It has been entertaining to read others thoughts on it however ;>). One guy must be miserable??
Thanks to freedom475!, who noticed the gap between tang/plug in that first photo a simple fix became apparent.
here is photo with different tang,, This might help a t/c owner some day?? t/c had several variations on these over the yrs which makes a perfect drop in difficult..
