Thread Nets

February 2011


By using thread nets over the spool, just about any brand of thread or size of spool can be used.  The thread net vertually eliminates tangles that are a problem with stiffer threads if not constrained on the spool.

Getting a straight blank. . .There is an excellent article containing recommendations from leading makers in the March/April 2010 issue of The Planing Form.  Check it out.

Some areas of a blank require more binding pressure.  These include the swelled butt and the swell at the transition to a bamboo ferrule.  Any place where there is a rapid change in dimension more binding pressure is required to avoid glue lines.  For example, when starting the binding on the butt end and proceeding thru the grip area, the dimension of the strip starts to decrease at the start of the swell.  In this area, the binding force is attempting to bend the strips in a convex fashion (enamel on the outside of the bend) which because of the power fibers, is the direction  most resistant to bending.  Unless extra binding force is exerted in this area, the blank will be prone to open glue lines.


An alternate solution to the problems is to “weaken” the strip at the start of the swell and negate the need for more wrap pressure.  Tim Abbott proposed this solution in a July, 2005 issue of the Planing Form.  His solution is to hollow the strips at the point of the change in dimension.  This is very effective and in no way affects the strength of the rod.  The sketch below better explains this technique.


 The binding string is attempting to bend each strip around point "A".  Hollowing at this point makes bending much easier.


The conventional 4-string binder as well as the Bertram 2-String Binder, operate on the principal of minimal thread tension and many closely spaced wraps to multiply the binding force.   To increase the effective pressure on the glue joints, one needs to feed the blank into the machine at a slower pace to space the wraps closer together.  It is also possible to over wrap by reversing the feed direction.

 Whenever I want to put extra binding pressure on a rod for insurance, I secure a length of heavy thread to my workbench and manually over wrap the area needing attention.  By keeping the hands close to the thread, high force can be exerted without bending or twisting the section.

Plugging of the exhaust can be nearly eliminated by using a very simple system.  Use a 2” PVC pipe as short as possible from the exhaust port of the Multi-Track into a cyclone collector.  The collector can be home-made from a 5 gal paint pail.  The combination of the smooth bore PVC pipe and a very short flexible tube from the collector to the vacuum reduces pressure losses and allows the use of the inexpensive 2 gal vacuum unit produced by Black & Decker.  Note from the picture that the beveller was elevated to give the PVC tube a straight shot into the collector.  You will find that 95% of the debris stays in the 5 gal container.


You can also drill a 1/2" hole in the plastic guard to allow clearing any plug ups at the entrance by inserting a strip into the hole.

For those using the Multi-Track Beveller for quads, it is possible to taper two strips at a time in fixture #3



January, 2010


A squaring fixture is now available to trim the edges of the strip and reduce the need for heating and bending to remove kinks at the nodes.

This fixture #1a is available for $35 + 5 US shipping and will fit all Multi-Track Bevellers.  It has 2 grooves, 1/4” & 3/8” wide to accommodate both thin and thick strips.
