Here's a cleaning tip
On my Big Boy 45LC (and should be the same for all Big Boys) -- There is very little room to depress the hammer completely down while trying to remove the bolt. It is tedious to say the least.
Find one of these hook and loop cinch straps that have a buckle. Then to remove the bolt, simply take one screw out to remove the lever and strap the hammer down tight. It will give you about .050" clearance on the bolt. Easy peasy with no marring anywhere.
As for the cinch straps -- I bought a combo package of Envisioned from Amazon. Various sizes for which I use in other jobs. I guess there are other outlets but this was the easiest for me.

For the Henry, I use the 3/4" x 8".
