I've posted these on a couple of other forums, so might as well share them here as well. I bought a South Bend lathe a year ago and it's turned into quite an addictive hobby. Now everything I own has a bolt knob and muzzle brake. 
First one I tried was for Savage centerfire bolt handles.
bare jig
		
		
	
	
		 
	
I turn off the old knob and thread the stub 3/8-24
		 
	
1 1/2" aluminum blank
		 
	
all finished
		 
	
other designs
