Hi,
How long should a blade cut well before resharpening.
Does the lack of continued use ... affect the blade.
I shape about 15 -20 pieces of cane every 6 weeks or so.
After one year .... I always notice a routine decline in gouging ease.
Maybe I gouge the max 150 pieces per year.
More likely 120 or so.
Comments?
I use a single radius Ross gouger.

It depends mostly on the hardness of the blade (as it does with your reed knife) and to a lesser extent on the cane. I don't know how to account for the abrasive qualities of cane, but we all know some is harder than others.
A sharp blade (again, just like your reed knife) will give a nearly polished surface to the cut. As the blade dulls, the surface gets fuzzier. When it starts to get rough looking, the blade is crushing and tearing fibers instead of cutting them. This is counter-productive, so rather than counting pieces, look at the surface finish of your gouged cane and correlate this with when your reed results start to drop off. This is the best indication of when you need to resharpen.
It might be worth returning the blade to Dan Ross to regrind - that way the shape will be the same. And 2 blades would allow you to have a sharp one on the machine and one in the process of sharpening, so you don't get forced by your schedule to use a dull blade.

Mark,
So do I & that sounds about right. One pound of tube cane give or take. When it stops being easy to gouge, send it back to Dan for an "oil change." It'll come back to you rarin' to go.
Best,
john

And as long as you keep the blade free of moisture - maybe resting it on an oily reg or wad of cotton after you dry it - the length of time between uses will not matter.

Hi,
I do keep an extra blade now .... no need to deliver the entire gouger back to Dan once a year.
I do keep the blade over an oily piece of cotton.
There is no question that when the blade becomes dull - harder cane does not gouge well .... maybe that's what confusing - since it works well on some cane batches and poorly on others.
It's good to know that after 150 pieces of gouged cane means the blade needs to be resharpened.
Thanks to all.
By the way - I have the gouger for almost 16 years.
And my custom blades made by Dan ... which work quite well.
Mark
