Blackwood Timber Opinion's

I solder my bandsaw blades until they get too short. I made a jig to align the blade. Good alignment is essential. Soldered blades will break next time at a different spot.

Markus,
I should look in to doing repairs to my blades. I can weld and braze , I have never done much soldering though.
Do you scarf join them?
And do you know if silver or bronze brazing would be better, or not necessary ?

Hi Rob,

Generally the "soldering" employed is silver soldering/ silver brazing. Not sure which exact alloy is used tho', as I got given a small amount by my local friendly bandsaw blade supplier. Have used that succesfully for blade repairs, as well as other silver soldering, using appropriate flux, and MAPP gas.

I have scarf joined, but was informed by the saw mob above that they in fact butt join. That said, I have never had one of their blades break at the join either.

Right: silver brazing. Not soldering, sorry for the confusion.

It does not really matter.

I opened a new thread over in the tutorial section.

I decided to Rip some backs out and stack them like this, I did it this way with some wet Indian Rosewood that was wet and it dried OK ,
Any one had any bad out comes doing Blackwood this thin ? some are 4 mm some 7 mm
We dipped the ends in beeswax first, I might add a bit of linseed oil to the Mix , the straight hot beeswax is peeling in a few spots.
