Off-Center-Turned “Sammy” Spook
I always liked the shape of the Lucky Craft Sammy, which is a freshwater walk-the-dog lure. I wanted to make a larger version for saltwater use, and I wanted to make it reproducible for the Vega.
The Sammy isn’t cylindrical so I had to learn about off-center turning.
Below is a picture of a plastic Lucky Craft Sammy 128, which I based mine on.

Planning - Dimensions
The Sammy’s belly, top and sides are all different shapes, so I needed three different Vega templates. To make sure they were proportionate, I overlayed pictures of the Sammy onto a Vega template grid to trace the arcs.

Planning – Turning Points (Axes)
Now that the bottom, top and the sides of the lure were laid out, I had to figure out the head-on view, which was going to determine where the multiple turning axis (axes) needed to be. To do this I made a grid representing the end-stock of the wood blank. I placed a few turning points and drew arcs until I got the shape I wanted.
In the picture below, you can see the arcs created by each Vega template. The purple rectangle indicates the minimum dimensions of the wood blank (1.125” x 1.25”). I decided to use 1.5” x 1.5” x 9” stock (EWP).

Preparing the Turning Stock
Accurately measuring and punching 4 turning points on end-stock can be dicey, so a centering template can be useful. You can make one out of 1.5” x 1.5” x .75” hard maple: - Carefully measure & awl the four points
- Drill them through with a 1/16” bit on the drill press
- Insert 1” nails through from the rear
- Place the centering template on a simple square jig and tap the ends of the turning stock into it.
Remove the template and you are left with 4 turning points accurately punched into the ends of the turning stock.

Pre-Seating the Turning Stock
The biggest risk with off-center turning is breaking the piece. There’s a few ways to reduce risk of breakage, and the first is to “pre-seat” the piece on all 4 turning points before you start turning.
To do this, seat the piece in the lathe along all 4 axes -- compress it deep enough for the teeth on the head stock to bite into the end-grain. Now that the teeth marks are in the wood, you won’t have to compress the piece as much when you change turning axes.

Turning
Nothing special to say about the actual turning, except be sure to cut shallower and make slower passes than you normally would – and be especially careful to not touch the squared ends of the blank with the cutter – this is when most breakages occur.
Did I mention to take shallow, slow passes?

Nice Eric!! I watched a PBS special on off center turning for axe handles a few weeks ago.

Very nice. I've not done much off center stuff but supposedly a Steb Center makes it easier.

Very nice 
does the tailstock center go in offset the opposite on all three of those setups as well? just wondering |
The United States Constitution does not exist to grant you rights; those rights are inherent within you. Rather it exists to frame a limited government so that those natural rights can be exercised freely.
1984 was a warning, not a guidebook!
It's time more people spoke up with the truth. Every time we let a leftist lie go uncorrected, the commies get stronger.

Thanks, I wrote something up about the chip control box about a year-and-a-half ago (see link below).
I love the box -- almost every single chip goes into the dust collector.

Yes, the turning points are mirrored on both ends of the wood blank -- I haven't experimented with off-set axes yet. |
