Preparing Segmented Blanks |
|
|
|
|
Make sure material for segments
is planed square and true. |
I use a chop saw fitted with a
simple plywood stop, a bit of spring steel helps push cut piece away from
blade. |
Once required length has been set
it's a case of just turning the stock over against the stop to alternate
cut direction. |
|
|
|
|
I like to check for correct
angles with the disc sander. . |
Using the inner face against the
fence as the reference. |
I tend to do a whole batch of
similar segments whilst the machines are set up, then it's just a case of
assembling them in sets and gluing up..
|
Once glue is set they are rough
turned to neaten & bored near size before setting aside to allow wood
moisture levels to equalise. |
Making a Bangle and matching wood Ear-Rings |
|
|
|
|
Slice up a suitable dry log, this
is Cherry that is down to 12-15% |
Roughly mark out and bandsaw
blanks |
I work with a screw chuck so
drill shallow hole to suit |
Fit a piece of sacrificial wood
on screw chuck |
|
|
|
|
and screw on Blank. |
True up face and periphery, clean
up back face with parting tool. |
Mark Bore diameter, nominal 65mm for adult. |
Using slim parting tool separate
most of Bangle wood from core. |
|
|
|
|
Leave 3-4 mm of material at base
of cut, don't part right through. |
If doubtful about judging depth,
mark parting tool with masking tape, |
and use as depth guide. |
Turn outer contour. |
|
|
|
|
Apply Finish, I use Melamine
Lacquer. |
Complete parting off, remove
Screw Chuck but retaining Core on chuck for later. |
Mount Bangle on Chuck Jaws and
clean up parting edge and check bore size. |
Using half round scraper hollow
out just over half depth of bore, |
|
|
|
|
Make sure you don't hit Jaws.
I do it with lathe reversed for ease of use and vision. |
Sand and apply finish |
Reverse and clean out - blend in
second side. |
Apply Finish.
Note: Because inner rims are narrower than jaws, which are over extended,
dovetail does not mark. |
Making the Ear Rings |
|
|
|
|
Re-mount screw chuck & core. |
Contour face and apply finish. |
Make initial parting to width
with narrow tool. |
Contour rear face with narrow
tool & sand to finish, apply finish on rear as far as possible. |
|
|
|
|
Lightly mark centre and
measure/mark offset in required direction. Complete parting off. |
Prepare dished depression to suit
in MDF waste. Position disc in depression, adjusting disc and chuck inner
align offset point with tailstock centre. |
Apply small tacks of Hot
Melt Glue. |
Drill pilot hole. |
|
|
|
|
Open out, I use 13mm. |
Turn inner dish to back edge of drilled hole. |
Sand and apply finish. |
Gently prise glue off MDF, peel glue off finished surface. |
|
|
|
Note:
Take care not to let abrasive wander onto Glue, friction heat will melt and
smear it all over the place. |
Reverse disc and use drill to align, re-tack with glue. |
Turn and finish second side. |
All that remains is to carefully drill small 1mm hole for finings eye. |
