Topic tags/keywords: bandsaw blades crosscutting recycled beams timber band saw blades question pine bandsaw milling modern traditional shaker

Hey All- I’m looking to embark on a project that would involve crosscutting some recycled 10”x10” beams. (think: the back cover of the latest Fine Woodworking.) The wood will most likely be some hemlock or pine.

I’m wondering what type of blade would be the best option for this job. I know that with table saw blades, you want more teeth per inch for crosscutting, but in the world of bandsaw blades, more TPI generally means a narrower blade; and my application seems to be more resawing, which would require a wider blade. I’m looking for recommendations on brands, width and TPI. Thanks so much in advance for your help on this topic.

I’m no bandsaw expert, but I would go with a resaw blade (3-4tpi), as wide as your saw will tension. 1/2” Woodslicer from Highland would work excellently in this application me thinks. If your saw will tension a wider blade, say 3/4”, then go with that. Wider the blade, straighter the cut.

The general rule for bandsaw tpi is that you want no fewer than 1-2 teeth in the thickness of the material at one time. That’s why you want higher tpi for thinner stock. For stock 10” thick, on a bandsaw you want fewer tpi so that there won’t be too much heat generated during cutting. I don’t think you can expect to get a smooth finish cut on a bandsaw – you will need to do some sanding/scraping/planing of the cut surface regardless.

Thanks live- I’ve been leaning towards a 1/2 – 5/8 for those reasons. You’re right with the sanding/planing aspect- but i used to own a woodslicer, and it boy did that leave a great finish- so i’ll probably go with theirs again.

Have your say...
