Just because you have been told something long enough doesn't make it true. The world is not flat so you can't fall off the end of the known world.
1. Because of the design of the frog on a Bailey designed plane, the frog moves forward and backwards on corresponding seats.
The beauty of the design is, hypothetically speaking, the the two machines seats on the plane body correspond to the two machined surfaces or the frog and the distance is the same at any given point, so that no matter where the frog is positioned when moving forward or backward, the distance between the two mating surfaces remain the same. I say hypothetically because there is always tolerances in machining so it may or not be a prefect
rectangle.
2. Carbide inserted cutters or a jointer or planner are considered by most to be a must have option on that type of a machine. How ever it has come to attention a lot of people that tightening the inserts as tight as one can get them is resulting in a lot of broken inserts. The wedging effect of the flat head screws is expanding the inserts and cause the insert to brake. And by torqueing the insert to a specific foot pounds, the insert breakage can be eliminated. Okay so what are you saying? I am saying that just because it is possible to over tighten something doesn't mean it is necessary to do so.
It is said that a frog needs to be fastened to the body when flattening so that the screws don't distort the body of the plane. The thinnest part where the the screw goes through the frog and the thickest part is of the plane body is where the taped hole is. To put it bluntly, if you think you can distort a plane body by torqueing a screw with a screw driver then maybe you should rethink your position. Just because you have been told something like the world is flat doesn't make it true.
3, On a hand plane the cutting force wants to push the blade back. Science says for every action there is a reaction. The hand pushes the plane blade into the wood being cut. But the resistance of the wood not wanting to be cut pushes the blade back. Also the wood being cut rises in the cut therefore pushing the blade back down against the frog. So the cutting force or splitting force of the wood being cut or split is down against the blade and back toward the frog.
4. On a table saw it is always a good idea to use a push block, or push stick, when ripping a piece of wood. Most push sticks have a little something that hooks over the end of the board so that when a board can no longer be pushed by the hand it can still be fed passed the blade. It takes a little downward pressure to keep the board flat on the table, but not as much as the pressure required to complete the cut on the board.
5. The frog adjusting screw is able to move the frog forward or backwards because of the little piece screwed on the back of the frog which, by the way, takes all of the cutting force ( resistance to being cut) away and the amount of pressure that the screws need to hold the frog down is minimal. All that the screws that hold the frog down in place is minimal.
6. So what are you saying? I am saying is tat all you need to do is to tighten down the frog retaining screw tight enough so that the frog can't be lifted up , but can still be moved forward or backward with the frog adjusting. I move my frog once in a blue mood so I am not going the wear out the adjusting screw or the threaded hole .Just tight ant over tight on the screws.
FOR the RECORD, The cutter can be advanced forward or backwards on a Bailey plane without removing the lever cap or blade and chip beaker or making any adjustments because it moves on a parallel design. With the Bedrock flat top design the cutter can be moved forward or backwards but still the cutter has to be readjusted.
I conclusion every body know that the Lever Cap and blade assemble needs to be remover to get excess the the frog screws on a Baily plane and that the Bedrock is far superior because every one has been told often enough by people that it is so. The Bedrock design which says the design is better is only better because marketing says so.
I have proved over and over to myself that the Baily design works and I hope you try out what I have written. And just because it can be tightened enough so no one including yourself can loosen it is not always the thing to do. Sometimes just tight enough to do the job is good enough.
