But I couldn't help myself! I said earlier that I wouldn't be working on the CVA '58 kit until I finished another project. Went to the basement last night to work on that project, but kept looking at the box of kit parts. Finally got the frame out along with the hammer, cylinder arbor and trigger guard. Those are the parts that wouldn't fit (may be more fitting of the action parts later). A bit of filing with a fine toothed flat file and the hammer falls into place! Just milling and drilling burrs on the inside of the frame. Same with the arbor, trigger guard took a little more filing and now it too fits nicely. No more than 10 minutes filing time. I am in a better frame of mind now about the gun.
