Woodturning Bobbin For Wire Weaving Jewelry


Hi, Alan Stratton, from As Wood Turns. (www.AsWoodTurns.com)
My wife decided to take up wire weaving which then added one item to my honey do list. It is a weaving bobbin which, by rights, should
be a very simple project except that it has five cotter pins here in a circle that need
to be equally spaced. I use VicMarc chucks and they seem to have
this very nice indexing mechanism on the back and on the side. But, I have never seen any official way that
you’re supposed to use this, or any attachment to the lathe so that you can actually use
the indexing arrangement. It does look like a good idea rather than
to have a dedicated indexing ring. So, I decided to make myself this jig which
sits on the bid of the lathe. It has a little nail here at spindle height
that engages the slot. Then I can index as I go around. I’d be very interested in, if anybody knows,
how they actually intended these to be used in an indexing situation. Meanwhile, let’s make the wire weaving bobbin. This wood is a scrap piece of walnut. I’m mounted it between centers and tool
it to round. But, most importantly, cut a tenon on one
end for a chuck mount. Now that the wood is in my chuck, I’ll use
this opportunity for skew practice – something I always can use more of. I’m targeting a diameter of about 2” for
this end. That should be enough to drill and to retain
a set of stainless steel cotter pins. As I approach the target diameter, this is
a good time to drill out the center. Unfortunately, my drill bit will not drill
entirely through the three inch length. Then sand this area. While I’m here, I’m cutting a shallow
groove where I will want to drill for the cotter pins. Now to index for the cotter pins. I’m covering the dark walnut end with masking
tape so I can see the markings. But, since I could not drill through the length,
I’m cutting a shallow groove near the end that I can use for a dovetail chuck mount. Then trim down the opposite end to a pleasant
but simple shape. Now for the actual indexing. I’m made an L shape out of scrap with a
small hole drilled at spindle height. I’m holding the L against the chuck with
a dulled nail. Then mark off in 75 degree intervals. Actually, this is slightly more than one full
rotation but it will do. I’ll drill the holes later on the drill
press. Then quickly sand before parting the bobbin
off from the base. I’m swapping chuck jaws for a set that is
slightly smaller. Then drill out the remainder through the spindle. Since this is the “output” end of the
bobbin and does not need to hold cotter pins, I’m enlarging the hole a little more. This will avoid a kink in the woven item. Then sand and apply brushing lacquer. Later I drilled the holes for the cotter pins
where I marked them and set them with a hammer. Here’s where I usually say how I like my
project. But all that really matters this time is that
it works for my wife and she likes it. I guess it is true because she has now ordered
more with different sizes and different numbers of cotter pins. I’ll save my admiration for the wire weaving
jewelry she makes. That’s it for this weaving bobbins. Please give this video a thumbs up, subscribe
