Band saw Blade Guides

Our blade guides are very simple but sturdy devices for use only in tight radius sculpting.  Their main function is to serve as a visual reference for the operator that tells him/her when the blade is getting off its nominal center.  We know from experience what happens when the blade gets wrapped around a .5" radius roller guide (even briefly) at 1725 RPM; you start breaking blade welds (metal fatigue).  Lower Blade Guide Extension or LBGX post on custom-built industrial band saw

They're spaced far enough apart to see a little gap on each side of the blade.  If you use blade guides to bully the blade through a log by over-driving the feed, you're just going to end up with squirrelly cuts and wasted wood.

Check out the video (#1 below) of the Mesquite log we ripped without any blade guides if you doubt. 

But then, if you really want to cut tight corners, these are the blade guides you want to use.  To see 1/2" radius turns, see videos #2 & #3 below.


Video demonstrations of blade guides' inaction:

Radius Plug Demo Narrative

A demonstration of band saw blades with high set angles both ripping and turning.

Radius Plug Demo Prequel

You can hear the blade guides squealing and the wood ripping. The trick was to keep the blade in the guides without going forward; it’s a slow, steady, twist: letting the set angle turn the blade into a .5” radius.
How many woodworkers can turn .5” radius with a .5” blade?

Ripping Without Blade Guides

Truing this mesquite log without blade guides shows how properly tensioned blades on properly crowned wheels are hard to deviate and how much resistance they offer against the force of feeding wood into a cut. Even thrust support bearings are optional if you let the blade do the cutting.
