Ever had this happen?

Vlad


>I'm using my LV block plane to square up an edge on a very large bench that I'm making for my shop and noticed that the center of the sole immediately behind the blade has changed colour. It's a bluish grey colour. I'm thinking it's a result of heat. I can't imagine anything else. There must be some micro vibrations/chatter between the blade and the sole/frog. My shavings are approx. 10 thou thick. Much thicker than normal. I haven't checked it with a straight edge, but I will. Weird eh??

>Hi Vlad,

Same block plane you had trouble with the mouth slipping lately? Is it just stained from the wood? What kind of wood?

Funny problems seem to keep happening with the same plane if it is the same one. Once again, you do know you can return it, right?

Take care, Mike

>I suspect a small bump in that area, behind the throat, possibly caused by overtightening the spin wheel, combined with a reaction from the Tannin in the timber.

Have often noticed this with English oak and sometimes cherry.

>Hi David,

You're right. It is oak but not english - if it makes a difference. As you can imagine I am putting some kind of pressure on it to get a 10 thou shaving. So you suspect it's tannin? If it is it should clean off right?

Hi Mike, Yes I'm sure LV service will let me return it but I don't feel right doing it as it's 3+ yrs old.

Cheers

Vlad - go Ghana :o)

>Almost certainly tannin/steel reaction.

Wire wool and metal polish will fix it in a trice.

I still suspect a micro bump.....

>That's why I asked what kind of wood. But note that sometimes the reaction can discolor deeper than just the very surface due to porosity of cast iron. Doesn't hurt anything.

As for the possibly sole issue, I would merely afix some 400 grit paper to a known flat reference and take a few swipes. Not only would it help the discoloration, but would also remove any possible micro bump...just retract the iron above the sole ...

Take care, Mike
