Bandsaw Guides Views
There are many types of guides available, and I will go over a few of the most common later. But in my opinion, no matter which type you have or choose, always go for bandsaw guides that can be greased. There are cheaper guides that are not greaseable but they are nowhere near as long lasting as a greaseable guide. Overtime you will find that you have to keep replacing them, so then any savings made at first are very soon lost.
Your bandsaw's lateral guides keep the blade from twisting as you begin cutting a curve. They also help damp out harmonic flutter and vibration, so your kerf is smoother, cleaner and as narrow as the blade allows. The guides keep the blade from deflecting easily under heavy feed pressure, and they also contribute to keeping straight cuts straight. The closer the guides are to the blade, the better the can carry out these essential chores.
Bandrollers are very cleverly designed to slip right into your saw's 1/2 x 1/2 guide holders, with no new hardware required. They're available to fit Delta 14 bandsaws with one lower guide angled at 45t°, and Taiwan-made clones with all four guides straight. You'll still want a set of Cool Blocks for scrolling with 1/8 and 1/16 blades, but all your blades 1/4 and wider will give you their very best performance when you put Bandrollers on your saw.
Why buy? For the best results on your bandsaw, the blade must cut perpendicular to the table; but blades can twist or wander from the mark. Worn or ineffective blade guides and thrust bearings take the blame here, especially in older saws. These replacement guides, ranging in price from $16 to $150, deliver increased accuracy. Better still, they fit any 14 bandsaw, as well as many other models.
