Bandsaw Bladeguide Carbide Replacement

Thomas Paine · Nov 10, 2017

Hey guys whats up, i haven't been here in awhile i kind of miss it compared to other forums, people are too nice on other forums.

We have a few large steelcutting bandsaws with 2" and 2.5" wide blades.

The manufacturers are quoting insane prices for new bladeguides, do you guys have an referrals for a US companies that re-braze the carbide inserts in these? We tried doing it ourselves, but my young guys cant keep them flat or the carbide simply just falls off :ack2:

Thanks for your help-

What do you consider insane prices?

If I was going to silver braze pads that large I would be using a rosebud on oxy-acetylene. Anything smaller and it will take to long to get it to temperature. Anything longer than about 10 seconds from when the flux melts until the braze joint is completely finished and your flux loses its ability to protect from oxidation.

If out of parallel is a problem, grind the pads after brazing. Do the bladeguides have to be a specific thickness, or are they adjusted for proper fit on the blade? If they are adjustable, can they be ground once or twice to restore the proper surface before fitting new pads?
