I'm not exactly certain what you are after- "step above the rear thimble"?- The rod is a 7/16" Hickory, non-tapered, with a tapered rod end for the Bess from Track. There is only enough wood below the rod to maintain integrity- no more than absolutely necessary- perhaps 1/8" between the hole and the outside. I suppose from the wood of the rod channel to the bottom of the thimble, there's 1/2" depth? I haven't the musket here to measure. The swell is slightly smaller than on my Sea Service, although the Sea Service is supposed to be smaller, I think as this area was slimmed by the 1780's. I do think the swell is slightly large on mine, but only measures .440" depth so perhaps Taylor's is only 4/10" or .400" not 1/2". Or, perhaps you mean from the forewood, ahead of the swell, to the forewood behind the swell(thickness?) - that's about 1.4" just ahead of the swell to 1.550" just behind the swell.(measurements from my Sea Service musket, which I might add is becoming nicer looking, the longer I have it.) I can't get over how well it handles. As the original Sea services weren't as nicley made as the earlier Bess's, & I assume this model is the same, I'd also assume a "sporterized" 1756 would handle as nicely and look nicer to boot. I do believe the 1728 French musket to come this fall (to me) will be a very nice looking musket - especially for the price & make a nice sporterized, slghtly heavy, Tulle' as issued in Lower Canada in the very early 1700's, along with the '28's.
: I have a low sight on the Sea Service now, that points very well. As I was able to solder it on a bit to the right of the lug's previous position, I might not have to bend the barrel, and it still points and AIMS well. It was shooting about 8" right of the bayonette lug at 100 meters, and I assume the change I made might be all that's necessary. For charging critters, I have the plug bayonete that is in the picture.(& a .44 :
I do like the plug bayonete as it has an 11 1/8" cutting length and is 1.8" wide ahead of the hilt. It would make a nasty wound.
