Rick,
You appear to have your post configured in some way that does not allow a reply from others. Also, a search of topics will explain how to post pictures.
As to your problem of barrel/lock relationship and the hammer position. If the bolster/drum is too far forward, you can simply re-inlet the barrel and tang further back. If the bolster/drum is too far back already, the simplest fix is to cut the hammer about mid way, remove the appropriate amount of material and weld it back together. This will correct the "fore and aft" problem but you will also want to consider the face of the rebate in the hammer nose so that it is parallel with the top of the nipple on the horizontal axis AND centered on the center-line of the nipple. This "Squaring" the hammer to the nipple will require the application of heat to the correct place on the hammer and then make the appropriate bend(s). An acetylene torch with a small tip will allow you to apply intense heat in a small area and control the required bending.
Good luck,
Jim Westberg
