Well... The spray was a failure, now onto a brushed Dulux Gloss paint. Safe and easy. Fraser

I'm sorry guys, My girlfriend convinced me to get spray enamel paint... So much for traditional! :( So far it's cost me about £40 just to paint it :( Fraser

Sorry Jacob, didn't realise you were a saint. Fraser

Actually, the lazy carpenter I am when it comes to sharpening, I wouldn't be surprised if my jack had done over 800ft. Yes, it's not sharp anymore, yes I should sharpen it, but yes, it still works for what I need it to do. You remind me of someone I knew at school. When someone was persistent in...

I am yet to understand why, when one was doing an experiment, that someone could not make 800 passes on a piece of wood? Do our bodies stop working after 100 passes or something? Whether or not you think you should hone before this, this experiment merely shows what happens when you don't. Why...

Did you not read the post? It's a drawing of the blade edges as wear forms. It's irrelevant that it's a shoulder plane, it could be any plane with the same angle. It's probably also largely irrelevant what wood it is, a harder wood will wear the blade faster. It wasn't there to tell you not to...

It's a lot, it would be reached slowly, and in reality the plane would be honed many times before you got there. So because you reckon 800ft would take a long time to get to, then you're skeptical of the science? Fraser

The point was Jacob, showing how quickly 800ft could be reached. 800ft is not an unfathomable amount. Fraser

Personally, I dry grind all the time when I get old tools in and want to get them going quickly. I also made a knife recently and even after hardening and tempering I still dry grind. I switch to the tormek when I want a good clean bevel, as with the guide it's much easier to get a nice grind...

Not him, just his argument! :mrgreen: Fraser

Jacob, your argument is somewhat ridiculous here. You mention that a door has 8ft of shoulders, and given that the shaving thickness is 0.002" thick, I highly doubt that you would be giving each shoulder 1 pass. Extrapolate this out to 4 passes per shoulder, and you're suddenly at 25 doors. 4...

Corneel has nailed it! Thanks! Fraser

Yes we do, or I do at least. However, so far we have ignored the coefficient of friction, and the energy needed to overcome friction. Fraser

Actually Jacob, Mike has made a good point here. My physics only work up until the point where the impulse on the plane is greater than the energy needed to push the plane. For small knots, this will not be the case, and therefore the above stands, but for larger knots Mike is definitely right...
