Re: spiller and burr revolver kit
sounds like you have made up your mind for a kit.
not much work on the wood grips, basic shaping & final sanding, staining.
depending on the maker of the kit you could be faced with hours of hand filing, to remove milling marks, then more work to remove file marks by hand sanding and further metal polishing then bluing or browing of the metal.
then, you have to check for proper cylinder indexing & timing. you could have hours of work ahead of you or just a few...all depends on the quality of the kit.
my own opinion is the kits are thrown together with parts off the assembly line that haven't even been seen by quality control inspectors.
50% chance everything will fall into place 50% that lots of work is needed.
and why should there be a complaint...the buyer wanted "A KIT"
my advice is to purchase a single shot muzzleloader pistol kit with a blank stock. or a kit that has a stock somewhat shaped & inletted but needing final fitting work.
that will provide you with the wood working experience you desire without all the metal work & possible mechanical issues that you may not want to tackle.
good luck & enjoy!
