Re: [TCML] Table Saw Blades for Phenolic LE

Terry -

Almost all the major saw blade manufacturers offer "blade stabilizers" for 
table saw blades.

These are 4"- 6" diameter circular plates that clamp against one side of the 
blade to stiffen it, reduce runout and damp resonance, which can cause a 
rough surface finish and a kerf wider than the actual blade width. All the 
ones I have seen have the blade-facing side "relieved" a few thousandths of 
an inch so they contact the blade only at their outer diameter. Some have a 
rubber o-ring inserted in a groove on the blade-facing side to further damp 
out any resonance or ringing.

These almost always will improve the quality of a cut, but will obviously 
reduce the maximum depth of cut. With the type of plastic materials usually 
used in Tesla coil systems, not an issue, as most plastic stock will does 
not exceed 1" material thickness.

I don't know if this is an option, but I would find a blade that is as
rigid as possible (sounds odd, but let me explain). The blade I
currently use seems to fall into some kind of resonance (blade will flex
laterally) and will cause the cut to widen periodically as I cut this
kind of material. I'm not sure why (feed speed has no effect on this) it
only does this on this material. Wood, aluminum, etc will not do this,
but for some reason, the phenolic and carbonate type material does.

Dan,

Carbide tipped wood cutting blades are fine for this.  There
will be
lots of dust.  I don't know how toxic it is, wearing a mask is
advisable.
