..are made closer to the vintage patterns, of course (and they look wonderful). I'd guess his plane (with the thicker iron and slightly more substantial lever cap, etc) is probably 6 ounces heavier than a typical norris A5 (I had two of those, both were beech - there actually fairly light - if more than 4 pounds, I"d have been surprised, but they weren't good planes in later trim in beech, either, and required a lot of work just to be tolerable. Tolerable was all I could get out of them. The adjuster was coarse and tough to use, and adding tension to the lever cap increased cutting depth, so the lever cap would become a secondary adjuster of sorts and allow several thousandths of adjustment in shaving thickness.

I copied (buying the lever cap and iron from Ron) Ron Brese's pattern for a "sort of" norris #13 single iron. Same metal thickness that Ron uses and bois de rose (boy would I like to have that blank of wood back - didn't know what it was) infill for a 2" plane and it came out around 5 1/2 pounds. It's a very pleasant plane to use if you use it for what it's good at, but not very productive for more than finish smoothing.

It'd be great to see a huge spectrum of weights, but it's hard to find good information. The first time I was really alarmed about the weight of a plane, there was a small spiers dovetail smoother on ebay, and the seller said that it was 2 pounds 15 ounces. I passed on buying it as I feared it wouldn't be heavy enough to work well (open handled and dainty). On the other end of the spectrum was the loopy...can't remember the weight, but I think that plane was a ruse (at least at first).

CS lists darell hutchinson and holtey a13s at 5lbs 15 oz and 6 lbs 2 oz, respectively. Karl's 98 at a little over 4 pounds.

at 5 1/2 pounds, my #13ish copy does feel heavy at 2" of width and it would be awkward trimming small things.
