One final note on this topic - this one covering bevel down scrub irons. I made up a jig and took an old Stanley #40 1/2 blade through grinding and honing. http://www3.telus.net/BrentBeach/Sharpen/scrubjig.html I have also reorganized all the pages dealing with cambered blades. I think one...

A reader of my camber page, Mark Wells, figured out a simplification of the jig that I have documented http://www3.telus.net/BrentBeach/Sharpen/camber.html#jig2design His modification can be used with any shape iron, but it works particularly well with cambered irons. Other threads on this...

When you tilt a circle you get an ellipse. The major axis of the ellipse, the horizontal axis, is unchanged. The minor axis, the axis along which we measure the camber, does change. When grinding/honing an iron to have camber I don't worry too much about whether the resulting shaving has...

In fact, I show grinding and honing for all three primaries. In an attempt to look all around the problem, I modelled each angle Lee Valley sells. These models are like engineered drawings - they are exactly what you have. All lengths are accurate to fractions of an inch and angles to...

Hi Some time ago, perhaps even a couple of years, there was a discussion about cambering plane blades and the difference between low angle and regular bench planes. I have been learning Google Sketchup and have finally been able to draw a model of a cambered plane iron. Using these models, I...

I have given some thought to side sharpening (google "side sharpening" to find my thoughts -- sorry I am a newbie and cannot include a URL) and would be very interested in reading David C's comments online. Brent

Ivan was a little ambiguous when he said . When the abrasive is wider than the blade, the edge can be very straight. With Derek's wide abrasive belt, he can put straight edges on very wide blades. However, when the abrasive is narrower than the edge, there are problems. Notice that working a...

Well, as one who has read a lot of results that worked in practise - that is, some one claimed to be able to do something - but were not reproducible, I have to take BugBear's side in this. In fact, in Mike's own (and several other people's, including mine) recommended solution, he explains...

A very interesting discussion, in which I have learnt a number of things about cambered blades. The similarity between the template and the blade shape leads one to the conclusion that one can only lead to the other. BugBear has noticed and explained well the weakness of the linkage. People...
