Tagua Nut Advice Sought
 

Hi,

I am not quite even a novice turner. I've bought a lathe, had one lesson,
and I'm playing. I've successfully made a couple of very small vases, 1-2"
tall.

Now I'm trying to work with a tagua nut following the instructions in the
article in the FWW compilation, Lathes and Turning Techniques, and which was
originally published in the July 1990 FWW. The article suggests sanding
down flat one end of the nut and gluing it to a 1" dowel with Super Glue.
I've tried this with old glue, new glue, waiting an hour, or clamping it
overnight. In all cases, the glue joint has failed as I begin trying to
rough the nut into round, no matter how gently I try to work with the gouge.

All further suggestions are welcome.

Thanks.

George

odd - I've never had that problem - is the glue failing by releasing
the nut, or by not holdng to the dowel, or is the glue spltting in
half?

my first guess would be that you aren't getting enough surface area in
contact, sand a flat that is at least 3/8 inch in diamter - and it
must be flat - use 120 grit or so to leave a bit of roughness, let it
dry and then test it and see if it's gripping well.

If you want to be extra secure, you can turn a 1/4 or 3/16 tennon on
the nut and make a matching hole in the material you will use for the
base - I usually use something dark - ebony or cocobolo - for the base

Hi George,

I turn a waste block mandrel about 6 inches long with a taper near the
end. I turn the small end a bit larger than the end of the nut I'm
going to glue to it. I make concave indentation in the end a little
larger than the end of the nut that will fit in it.

My mandrels are mounted on homemade faceplates but before I made them
I used a scroll chuck to hold the waste blocks. Except for the short
taper on the end, I make the mandrels a large diameter to prevent
flexing (2 to 3 inches).

I use 5 min epoxy glue to glue the nuts on. After mixing the glue, I
fill up the concave end with glue and stick in the nut. I use the
tail stock to apply just enough pressure to keep it from falling off
until the glue sets.

Rotating the waste block by hand until the glue reaches the gel stage
prevents drips but just in case I cover the lathe ways with a piece of
cardboard to catch any accidents.

Once the glue has set, I remove the mandrel & nut from the lathe and
allow the glue to cure fully. I usually wait overnight but I have
turned some after a few hours. I use the tail stock for support as
long as possible.

I've used this method for a while and so far I haven't had any
failures do to the glue joint.

Hello George,

Welcome to the world of woodturning. You don't say what form of CA glue you are
using. The super thin stuff will not generally hold a tagua nut or two pieces of
anything together very well. It fills cracks very well, but I've always had
problems trying to glue two pieces together with the thin glue. The medium CA
glue is the proper stuff to use. It takes a bit longer to set, but generally
holds well. Coat both surfaces with the glue by rubbing them together. Separate
them and spray one side with fixative. Then quickly but them back together and
hold in place for one minute. Allow a couple of more minutes for it to set up
properly and you are ready to turn.

I have done a few of these, and I use the thicker CA glues and the
accelerator. The thinner stuff doesn't fill any of the gaps, and won't
hold. With the accelerator (I spray the nut) it is ready to turn right
away. I mounted it on flat grain wood, as I feel that makes a better
glue joint.

George,
It also helps to bring up the tailstock until you have the nut roughed out.

Now that you mention that, Tony... you sparked a memory that a senior moment had
blocked..

When I'm gluing something to a scrap block, or in this case a dowel, I do it in
place... hold the block in the chuck or between centers and use the tail stock
as a clamp to keep pressure on the adhesive...
I've found that a bit of clamping gives me a little better feeling about even a
CA joint...

adding to the other good suggestions, it sometimes happens that a nut
that is not 'quite' dried will have a bit of oil in it, so when you
try to glue, it is not gripping well. A little solvent wiped over the
flat spot before applying glue may help. Being sure both the dowel and
the nut base are flat is important, as is using the medium-thick
glue. The tail stock allows you to do the bumpy roughing with relative
safety.
