Some general weight adding tips from my side:
- cut of a nail, welding rod or whatever of the desired weight to add to your front end
- make a jig to asure you'll drill right along the axis of each shaft
- from the front and befor cutting the taper drill a hole into the shaft, diameter according to point one above
- make sure each hole is the same depth
- epoxy the "insert" into the shaft
- cut taper
- glue on WW as usual
In addition to the above you can also epoxy a .357 Mag casing (cut bottom of first
behind your Bhds.
Use havy hardwood footings to give more weight to the front end of your shafts.
