For the barrels I used 2" drawn brass tube. 1 3/8" long. Faced off nicely in the three jaw chuck.
The four endplates are out of 3/16" sheet. All the centres are drilled and reamed to the 5/16" for the arbors. Two of them will be the ratchets and are turned down to 2 1/8" dia. The other two are 2 1/4 dia with a spigot turned to fit the barrel by using a mandrel in a collet. A spigot is also turned on the ratchet ends only 1/32".
Next I groove/screw cut the barrels. Silver solder on the endplate, mount it back on the mandrel with the tailstock applying pressure in the endplate hole.
Set the lathe up to do 14 threads per inch and take very light cuts remembering backlash so you have to come out furthur (towards the tailstock) to keep on track.
