Hello, I think you mean momentum, not inertia, but your point is correct and what I have been saying. Mike.

Hello, Whatever the number, there really should be an odd number of tenons, so three is as good as any. What does the OP intend to do about the look of the BB ends when the wood movement of the main tabletop makes them not flush anymore? I have made BB ends deliberately longer and put some...

Hello, Not going to get into a silly *** for tat, as I said plane weight is personal preference, and I have used light planes and heavy ones and in between ones, it really doesn't matter. BUT, you can't go trying to prove lighter is better, by spouting twaddle. No, you cannot have a massless...

Hello, The momentum required to make the cut is the same no matter what plane is used and who is pushing it, otherwise it will stall. Momentum can be achieved with speed in a light plane, but since the action of cutting wood acts against the plane, there is only so fast a plane can go. Mass is...

Hello, I use a ramped shooting board, and they are very useful. Mine is ramped high towards the fence end, so it does not have a tendency to lift the stock off the board, and the ramp angle was decided on, by the maximum width of stock I anticipated planing. I figured about 8 in wide would be...

Hello, Concluding that a close set cap iron negates the need for the blade back to be as finely finished as the bevel, is about the worst logic I've come across. It is the meeting edge of the back and the bevel that does the cutting, the level of polish that we see is only an indicator of what...

Hello, A paring chisel with a back bevel? That would be a fairly useless tool. A dovetail chisel chopping to a knife line with a back bevel, similarly useless. As regarding finding lots of old chisels with back bevels, so what? If we look to old tools for how they have been looked after, then...

Hello, Just lifting it a bit, prevents cap iron effect, since the cap cannot be put close enough to the cutting edge. The ruler trick offers consistency so a longer back bevel can be produced, into which the cap iron can be set and therefore close enough to have a cap iron effect. If the iron...

Hello, This is all correct and essentially what I was saying. However, there is no free lunch. A 45 degree EP or not, the cap iron set close has an effect that setting it back does not have, there is no magic (as good as it is). The leading edge of the cap iron pushes the shaving harder than...

Hello, Yes, I agree that a surface of a difficult wood planed with strong cap iron effect IS better than a scraped surface, but is still not quite as good as a plane with no cap iron effect in a wood that will accept that, or a very fine mouthed plane for the very last finishing strokes after...

Hello, I agree about the best surface coming from very sharp, moderate angle planes. I think this is most true without a strong cap iron effect. A strong cap iron effect actually turns the plane into a scraper, and I find that although tear out is tamed, the finish on the wood is never quite as...

Hello, Using a smoother to plane to a finish ready board, requires very thin shavings. In fact in hard wood, they are not ribbony shavings at all, but wooly, crumpled up fluff. Now 'shavings' this thin require a camber on the iron of such an imperceptible amount, that any scallops to the...

Hello, I suppose it depends on what you mean by commercially. For a one off piece maker, who does expensive work and who wants to enjoy working tools rather than electric sanders and extractors, then hand planes are actually very efficient. Commercial makers doing volume work and to a price...

Hello, I'd be interested about the thought that Krenov keyed the surface from the plane before gluing. I have read all krenov's books and cannot recall that ever being written, though memory might be failing. He was anti sandpaper, in fact and wanted surfaces straight from the tool, whenever...

Hello, Just a bit of info that might be useful. Technically paste wax and the like IS an oil finish, so is compatible with Danish oil et al, before after or between applications. Linseed oil darkens with the absence of light. Use BLO or Danish oil with a high proportion of linseed and keep that...

Hello, Half section glue ups are done as a complete cylinder, just omit the glue from the centre staves. Tight joints and the facility to true up a slight error. This is useful on large cylinders, for sure, where a bit of twist in the staves can be a pain. Mike.

Hello, Funny this, a few years ago there was a thread about scrub planes, and Jacob did not know what they were for! When he was put straight about their use, he began to repeat the correct usage as if he'd invented the damn things and when queried as to why he was doing so, replied. "I changed...

Hello, Hmm, I wonder what the cause is, when someone very experienced with tools finds a new tool a bit crumbly for the first few sharpenings, then improves? It would have to be some myth! New tools that are ground before hardening will have a brittle edge for a while, as the thin edge will...

Hello, There are definitely more than one way to skin this particular cat. I have made and seen others make, (we made an exercise of doing it) planes that could plane directly against the grain without tear out utilising no cap iron effect and all narrowness of aperture. It is plain daft not...
