Question: Are the wheels aluminum or cast iron?
Document: I consider it 'low-end' of the group because it lacks some of the features of the basic Delta, but also of the new 14&quot; Jet which wasn't available at the time I purchased this one.The Jet doesn't have cast iron trunnions which holds up the table, it's cast aluminum, so the table will flex under pressure. How much is ok depends on what you're doing and what you think you can tolerate.
I purchased this tool with the 6" riser block. The quality of manufacturing is great. I found no problems with the saw when I unpacked it and assemly was a breeze.This saw is very solidly made, cast iron. I LOVE the fence. Blade tracking is true. The blade does not wander while cutting. Dust collection is not very effective but this seems to be a common problem on most bandsaws.After using this saw for approx.
One, is the 4 inch dust collection outlets is absolutely useless. It's on the side above where dust wants to settle therefore most of my dust is either on top of the cast iron bed or slips through the bottom where the door opens to alloy you to change blades. It's either that or my Jet dust collector is crap. The latter is not the case because that works great for my other tools in removing dust and chips in my shop.The other complaint is the jet blade that comes with the saw.
The knobs on the Delta are out of the way so you can get your fingers on them a little easier. That's perhaps splitting hairs but it also supports the blade lower on the bottom while the lower blade support on the Delta is higher which supports the blade closer to the table.The Delta has a few extra spokes on its wheels so does the new Jet. Supposed to help cut down vibration.
I agree with another reviewer than a Carter type roller guide system is the way to go and will be installing one of these soon, but the "block" system that came with the saw seems to do an adequate job. I like the easy access to the motor and upper pulley. The hinged doors on the blade wheels are a real treat to someone used to having to remove the covers on the older unit.
These are typical steps in setting up any band saw, but the Jet is easier than other 14" saws.Installing and/or removing blades on the Jet 14" is easy. The upper and lower guides loosen up, and the blade slips out through the table without a problem. When installing a new blade, it's easy to guide it into the blade guard, mount it on the two wheels, and center it. Hint: when installing a blade, make sure the teeth are pointing DOWNward.
First, loosen a wing nut. Then, spin one of the wheels with your hand. As you spin the wheel, turn the tracking knob one way or another until you see that the blade stays in the center of the wheel. Then tighten the wing nut again, and you're done. This saw holds its tracking setting, even after hours of use.The next step is to adjust the blade guard. Jet's blade guard is a step ahead of the other brands.
I've owned this band saw for a year. Before purchasing, I researched others, including Delta, Grizzly, Ridgid, and General. I've written this review to answer the kind of questions I had when I was still shopping for a band saw!Assembly is simple. The manual contains photos of each step, with hardware and parts clearly visible. Aligning the upper and lower wheels is no problem -- they were aligned perfectly out of the box.
I recently purchased this Jet bandsaw and it has quickly become the pride of my shop. It cuts like butter through even tough wood, runs quietly, and cuts straight. The saw will quickly pay for itself through its ability to do excellent resawing, and the fence and miter gauge which were included at the time are excellent. If there's a better band saw out there for the money, or even close to it, I can't find it. Wheels were perfectly co-planer right out of the box.
It runs smooth and quite. I did replace the v-belt with a like belt. That quiets it down a bit more and reduces motor vibration. Which I should mention, getting the belt aligned and to reasonable tension is truly an art. I think some form of reengineered mounting/aligning method is well overdue.At some point I'll get the Carter automatic tensioner. This will essentially make it the new Jet minus the 9 spoke wheels. I might even check the price of the Powermatics Trunion.
