Size the blank to over the 3” desired diameter
at this point. The amount will depend on the alignment of your lathe
and its ability to drill on center. Drilling for the shafts may cause
some slight out of trueness that we will have to correct for later. |
 |
Rough the blank down to the sizing cuts.
The barrel will be finish turned later so do not worry too much with
surface finish at this point. |
 |
True the end of the blank in preparation
for drilling. An uneven surface could cause the drill bit to deflect
off center. I am using the long point of the skew. |

The funnel shaped starter for the drill. |
 |
I am drilling to a depth of 2” with
a 1/2” drill. The tape is my depth stop set for the 2” plus
the length of the tenon. |
 |
Chamfer the opening. |
 |
Seat the tailstock center in the blank and true the tenon
for the chuck if needed. We want the hole and the tenon to be concentric. |
 |
Reverse the blank and perform the same truing and drilling
operations on this end. |
 |
The Oneway cone center I will be using
to hold the barrel for the final turning. The small dummy rod holds
the center while screwing attachments on and off. The threads on the
center are ¾” 10 threads per inch. |
