Band saw blades

[kool55]

Where do you buy your band saw blades from? My grob 4v18 is ready for one.

Any local mill supply company that's worth their salt should be able to cut and weld you a blade. You just have to give them some specs as to length, blade width and tooth count.

I've been buying Bahco brand from Williams. They were the only ones I found that were cutting really tough steel and not breaking. I get them from some industrial supplier, local.

I have broken blades that I can't weld because they're too short if I do.

If by some crazy chance they'll work for you, this might be a cool way to recycle them. What size are you looking for?

 

[kool55]

My saw takes 150'' max. I ordered a 6-10 x 3/8 bimetal for steel and a 3-4 x 1/4 for wood. I found a place called Bandsaw Blades Direct. I think before its over I will have an assorted collection of blades.

If I recall correctly, your Grob had a blade welder installed.

If that's the case, you can buy coil stock and make up your own blades as necessary. It's convenient and will save quite a bit of money in the long run.

 

[kool55]

Thats correct. I got a couple of blades with the saw that are to short. I am going to practice welding on them.When I feel like I know what I am doing I will buy coil stock.

The welding is the easy part. The trick is in the anneal. You'll find that out when you discover the blades breaking at the weld.

+1 for finding out the hard way

I made a new video over the weekend that might be helpful, Kool55.

How to: Weld a Band Saw Blade

great video, that's what I do on the band saw at school. the video doesn't show much of the annealing process. basically you press the bottom, each time the electric current goes through the blades turns the weld and surrounding area red hot, but only let is last about half a second, let cool for 15-20 seconds then repeat 5 times.

A Pmech, Thanks for the video. Hope I can return the favor sometime.

Glad to be of help, Kool.

Enjoy your machinery!

Thanks! I tried to dim the lights enough so that the proper color of the blade could be seen. Unfortunately, my camera isn't the greatest and not much of anything was captured.

I've found that it is helpful to make a few "test coupons" from 4" sections of blade to refine my weld and anneal practices. With practice it is possible to weld, anneal and grind a coupon that can be bent back on itself into a U-shape until the ends touch. If one can pass that test, the weld should last longer than the teeth.
