After reading Mads’ blog on his new bandsaw fence, I postulated that an old blade that had been used to cut curves could not not be used for resawing. See https://www.lumberjocks.com/mafe/blog/130837
So I set up a scientific experiment. I will be using my outdoor laboratorium.

First I cut 4 staves of 1/4” plywood, marked both centerlines. Staves were 365mm. x 45mm. The Alex Snodgrass set up can be found here. https://www.youtube.com/watch?v=XYYG91fr_2w
1: Snodgrass old blade.
2: Snodgrass new blade.
3: normal setup old blade.
4: normal setup new blade.

I then set my fence 45mm. from the blade and started cutting.

This is Snodgrass with old blade. 20 mm. at one end and 25 mm at the other.

This is Snodgrass with new blade. 21 mm. at one end and 22mm. at the other.

This is regular setup with the old blade set in the middle of the wheel. 18mm. at one end and 24 mm. at the other.

Regular setup with new blade. 21mm. at one end and 21 mm. the other.

As this is not a rock solid proof experiment it just shows me that blades used for cutting curve and blades for resawing are two different animals.

As for my outdoor laboratorium.

Wauuuu thank you!
I will order some new blades and do some testing once this virus is at ease again.
I also found my saw most accurate with the blade centered.
Lovely to see your outdoor shop now.
Looks more like spring than here… we have 23°f / -5°c here at night now – stange spring here this year…
Thanks again my friend.
Stay safe and take care.
Best of my thoughts,
Mads
