Help buying bandsaw blades

I picked up a very clean Delta 14", HP bandsaw from the 1980's. It's in great shape, but the blades that came with it need replacing. I'm just a hobbyist. Which two or three blades would be good to keep on-hand for general-purpose work? Thanks.

The 3 blades I use ...

The narrow width blades like 1/4" will turn a tighter radius, so that's a good one. The number of teeth per inch, I use is typically between 6 and 10 TPI.

A 3/8" width blade I use for general purposes, like making tenons, average curves in plywood or 1 1/2" thick hardwood. I like an 8 TPI in this width.

Finally, for resawing on a 14" saw, I use a 1/2" wide blade with 3 TPI.

Watch this informative video on how to set up your saw and the tracking of the blades. By tracking the gullet on the center of the upper wheel, changing the blades guide for each different width is minimal or not needed at all.

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

Thanks very much, that's exactly the info I need; and thank you to whoever uprighted my photo :-)

I watched that very video yesterday and promptly disassembled, lubed, reassembled and tweaked the guides, bearings, table, etc. Good stuff.

I am sorry to deliver the bad news: There is no general purpose blade for a bandsaw. You can buy a general purpose blade for your table saw, but not your bandsaw. Sometimes you have to suck it up and change the blades more often than you want. It took me a while to learn that lesson.

Bandsaws do three things:

1. Resaw thick boards into thinner boards, as thin as veneer.
2. Cut straight lines - rip cuts, crosscuts, etc.
3. Cut curves.

The choice of blades varies by:
* The type of cut you are making.
* The thickness of the wood you are cutting.
* If you are cutting curves, then the choice of blade also varies by the radius of the curve itself.

I was going to write another long treatise on choosing a bandsaw blade, but I found this article, which may help you as much as anything I could write:

P.S. After a warning for purists, at the bottom of the article, they say that you can use a 3/8 inch 4 TPI standard-tooth blade as a "general purpose" blade. I am skeptical. ... but the next time I am near Industrial Blade, I might buy one to try. :-)

P.P.S. I buy blades from Industrial Blade:

P.P.P.S. Another great bandsaw resource is Iturra Designs, especially if you own an older Delta bandsaw. They are totally old school - no internet presence at all. They still have a printed catalog, and you call them to place mail orders. The catalog is a treasure trove of bandsaw wisdom, and prices are good:

Another good read:
