The Carter Guides
The first thing you wonder when you attempt to install the Carter guides is: 'Boy, can these directions get any more puzzling?' Included with the set for my saw was only one page of instructions. All the pictures on the page show my machine with the guides attached, blade installed and the saw table removed. Unfortunately the directions don't specifically address this and I was wondering do I remove the table or not?
Removing the table is no big deal on this machine - remove the two star wheels from below the trunnions and lift it off (after blade is removed). I tried it without removing the table and leaving the blade installed. This worked fine until I got to the lower section (left photo) when I had to remove the blade to slip the lower guides behind it. The two slotted machine screws from the original guides aren't used but are replaced with two Allen-wrench capscrews which seem much more substantial than the original.
After reinstalling the blade comes the alignment procedure. Carter suggests adjusting the top bearings first, then the bottom. I had a problem with this considering a variable which isn't addressed by the instructions. Depending on how your tensioned blade sits on a crowned wheel, it can come off the wheel at a slight angle. Whichever angle it is isn't important as long as it keeps this angle both top and bottom - no twist in your blade. Since they suggest a .002" free-space between the side-bearings and the sawblade, it seemed important to make sure the blade stays parallel to the bearing edges.
The upper guides can adapt to this angle simply by rotating the whole assembly slightly right or left on the saw's guide post. Without anything from the instructions, I mistakenly tried to adjust the bearings parallel to the blade by rotating the assembly slightly off center to the thrust bearing. When the upper assembly was finished, I found out I couldn't do the same for the lower assembly as it isn't adjustable. Instead, I backed off the bearings, re-tracked the blade to adapt more parallel to the lower bearings and then started all over with the top. (Groan)
One more glitch. The whole upper assembly relies on three set-screws to mount to the guide post. A bothersome design fidget is the set-screw directly behind the upper thrust bearing. In order to tighten this screw, the blade needs to be loosened and the bearing assembly removed if you are using a regular Allen wrench (not supplied by Carter). Fortunately I had a ball-end Allen driver (yellow handle - top photo) which let me tighten this screw from an angle. If Carter isn't going to supply such a wrench for their customers, perhaps they could move this screw to another point around the post. Any other point would be better than where it is.
Et un autre sur Wood Magazine
I spent a mere 15 minutes installing the Carter Conversion Kit on my 14" Jet bandsaw. It replaced not only the guides, but also my saw's entire upper and lower blade-guide assembly. I was surprised, however, to find that the two Allen wrenches needed to install and make adjustments to the bearings were not included in the kit.
I immediately noticed improved performance from my bandsaw as the bearing guides gave it a huge boost in accuracy. When cutting arcs and circular shapes -- and especially in resawing -- the bearings proved much better than my old graphite guides at holding the blade perpendicular to the workpiece with no twisting or deflection. Aside from the price tag, the only drawback I found was the increased noise as compared with my previous guides. But I'm willing to trade a little noise for the greatly superior cutting results.

Delta écrit: Ici leur kit de conversion , ils mentionnent que le roulement arrière est dans le même sens que la lame pour améliorer la direction.
je trouve l idée interessante . ca fait travaillé le bearing d une facon plus normale qu en poussant sur sa face comme la plupart des scie a ruban .

Je ne l'ai pas encore reçu. C'est moins cher que les Carter mais ça ne comprend que les roulements du haut.

j'ai mis le Carter Micro-Adjust sur ma Delta 28-276 (le petit modèle 14" d'entrée de gamme, similaire à la King) et je dois dire que c'est le jour et la nui comparé aux blocs standards. La lame répond mieux quand on découpe des courbes entre autre. Je ne retournerais pas en arrière...
Je les ai pris chez Dumais, et comme toujours service hors-pair.
