Bangles & Bits
|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.|
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.|
