I have some gunsmith specials (American sxs and singles) I purchased with the intent of trying different wood finishes. Some of these guns need the checking cleaned up a little. All the checkering is present it just needs to be recut. I've seen the different checking sets with 60 and 90 degree cutters, veiners, multi-line cutters, and the different LPI sets. I do not plan on starting from a blank canvas and checker a new stock just recut the existing so any input with the minimum tool(s) I would most likely need.
I always for forward to informed answers from this site.
