I am looking at buying a bandsaw soon. I got some xmas money that I plan to use to get a grizzly 17in but I don’t know if I should pay $850 and get the one without the CI trunion or $1050 and get the one with. The one without is on sale right now so will probably go back up to $950 soon. I really have no idea what having a CI trunion even means. Should I go with or without?

Other differences in the saws you are considering are
in what the wheels are made of (cast iron in the
higher priced one) and the way the blade guides
are made.

Probably the lower priced saw has a pot metal
trunnion and wheels. The wheels will have less
mass and so forth. Pot metal isn’t bad for wheels
and band saw trunnions especially, but cast
iron has more vibration-dampening mass and
can take harder use. For a small shop the
durability of the metal is not likely to be a factor
for you. My guess would be that the saw
with the iron parts probably runs with less
obvious vibration.

I think it would be worth comparing the two saws closely to see what other differences there are. Also, if the trunnions aren’t cast iron, what are they ? Things like the quality of the blade guides and the wheels, as well as the motor are every bit as important, if not more so.

They are both 2 HP. The other wheels are cast aluminum. •Blade guides: Euro-style roller disc with full enclosure protection. The table is 5in longer, the fence is CI instead of extruded aluminum, guides are ball bearing instead of roller disc, cast iron wheels vs cast aluminum.
What is the trunion?

I didn’t realized the blade guides were different. I really wanted the wheels

I have the grizzly 17” X2BF model and I love it. It has the cast iron wheels, bearing blade guides, cast iron trunnion and a magnetic switch (if the power fails the machine is shut off when the power comes back on).

I would defiantly recommend the more expensive version. Whether you want to have a foot break is your choice. I find that finding the break petal while keeping my eyes on the work is difficult. In an emergency I can’t imagine using the foot break.

I looked at the pictures and it looks like they are both
Euro-style blade guides, but different designs. It’s
hard to speculate as to whether one guide design
will be better.

Practically, all blade guides work. Some saws are
very well made and you can position the guide-bar
post anywhere without resetting the guides on
the sides. Usually you’ll have to back off the
back bearing to change height settings more than
a few inches. Certainly the Euro style guides
tend to be quicker to adjust than the block
style guides. For the most precision I prefer
blocks but height changes tend to be a hassle
with a lot of saws if you want to set the blocks
super close.

Roller guides are fine too, but because they turn
the side of the blade can run against one or
the other and the setups are more forgiving
that way. Best practice though is to back off
the guides if they are set “tight”, change the
height, then readjust the guides “tight” at
the new height.

thanks:) if the cheaper on wasn’t on sale it wouldn’t be a question. But I think that even at $200 more I will probably go with the better one. It will be $1150 with shipping…I’m not sure if that is with or without tax. Do they ever give out coupons?

sorry shelly

in answer to your question
the trunnion is the semi-circular casting
the table attaches to
and lets it tilt

the G0513 (the cheaper one)
doesn’t even show it
so maybe they aren’t too proud of it

Shelly- I went through the same decision you are facing several years ago and I chose the 17” Extreme Series and have never regretted it. The cast iron trunions and wheels add a lot of mass and stability as well as being stronger and more durable. When I looked at the features I wanted: resaw fence, 12 resaw capacity, cast iron, and the biggest table I could get, the decision was made! I got very lucky and ordered mine when they had a free shipping deal going on this saw as well!

Others have reported that if you request a Grizzly catalog they will include a discount coupon. This may be for new customers only (???). Before I was a Grizzly customer I ordered the catalog but there was no coupon in it.

You could post and ask if anyone had a discount coupon they would share with you.

If you happen to live in one of the states where Grizzly has an office they do charge sales tax.

I’m in Ohio so I think I should be good on taxes. Thank you! I didn’t realize that! I love saving money:) I will keep an eye on my email and check my magazine for coupons. Thanks:) I think I will go with the bigger better one. My birthday is 1/8 so maybe I will wait on that money…then I wouldn’t need to spend very much at all!

Shellly,

We have a 17” that came with ball bearing guides. The bearings were shielded bearings not sealed bearings. We use the saw commercially and use it a lot. I had to quickly replace the shielded bearings and I replaced them with sealed bearings thinking it would solve the short bearing life. It helped but on the second bearing replacement, I just bought the guides with ceramic discs. Even the discs require some maintenance but replacing 10 bearings every few months was expensive. The maintenance is just removing, cleaning, lubricating and reinstalling the discs.

Grizzly didn’t offer a cast iron trunion version when we bought our saw. Cast iron is better but we haven’t had any problem with the steel trunions. We do change the angle of the table frequently and the steel trunions are fine.

The one thing the saw doesn’t have is a break. I wish it did.
