Re: Hand planing survey

>I have a question for all you hand planers out there. I'm wondering how much time it would take you to plane the following board: 16 inch wide poplar, 2 feet long, rough sawn, dry, 1+ inch thick, slight cup and twist. How long would it take you to flatten it and thickness it to 3/4 inch.
Hi Adam (nice to have another Adam around here- that way I can blame any wrong or incendiary posts on you!)
When people made their livings using hand tools, they worked incredibly quickly (probably faster than any of us and faster than many with power tools.) 2 hours is absolutely an unreasonable amount of time to surface a board. 10 minutes is pretty much the tops for a board that size.
The process you describe doesn�t sound unreasonable. The difference between 2 hours and 10 minutes can be accomplished by:
1) Choose straight-grained stock that will be less prone to warping or casting. When working wide boards, choose only those close to the heart of the tree. Your 16� piece of tulip (it�s probably not poplar) is probably pretty close to the heart, so cupping should be minimal.
2) Only one face, the outer face needs to be smooth. And it needn�t be very smooth. Tear out from tiny knots or other imperfections are acceptable and often sought after. They enable people to distinguish between solid wood, and ply wood, hand made and machine made.
3) A slight cup can be clamped out. It needn�t be planed out. One advantage of dovetail joinery is that it will sufficiently restrain a board flat. Just remember to keep the board restrained all through the joinery process I usually choose heart side out for carcass sides (similar in size to your board) because the strain will be in the middle of the board (wanting to bow out). Complete the assembly in one day (should be no more than half a day for a carcass).
4) Thicknessing stock is almost never needed. You are probably just doing it because that�s what a power tool would do. Herein lies the problem many of us face; We are taught to work wood with power tools. The use of electricity isn�t the only difference between using hand tools and using power tools. There are different approaches.
1. How long would it take you to do a piece of wood like I mentioned above?
No more than 10 minutes. Probably more like 5. If it was a front or top, I MIGHT spend as many as 10 minutes to smooth and maybe scrape if need be.
2. What is your process?
1) Look the board over. Look at each edge. Try to understand exactly where it was in the tree and what it wants to do now. Select the outside face.
2) Remove saw marks with 16� wooden jack/fore plane, cutting 30-45 degrees across the grain. Its rounded iron cuts narrow, shallow grooves. Since the board is probably cupped in the middle (I probably choose the heart side for the outside), I�ll spend my time there.
BTW: This sort of heavy planing across the grain really calls for a bench with a rear stop of some sort. The all important tail vise is less helpful since we're pushing the board sideways.
3) With majority of saw marks removed, I�ll switch to my wooden smoother. No need to flatten using my try plane since the customer doesn�t care how flat the sides of his dresser are. Working the smoother lengthwise, I�ll freshen up the surface and remove any of the grooves left by the fore plane.
4) The dovetailed ends need to have a consistent thickness. I�ll set my marking gauge to the middle of the board (thinnest part) then gauge across the end grain. A few swipes directly cross grain with the fore plane will do the trick. Be careful to plane in from both edges to avoid tearing out the edge grain.
5) Lastly, I�ll straighten and square one edge with my try plane. This will take less than one minute. The back edge probably needs nothing. If the edges aren�t parallel, I�ll plane the back side, but if they are close, I�ll skip it. Usually, I do both sides as one board. As long as they are the same, it really doesn�t matter what the back edge is like. Since I pay extra for wide boards, I don�t want to needlessly plane away their width.
Although own many planes including a european scrub plane, these three plane suffice for 90% of my surface work. All have curved irons, as they should, IMHO.
3. Do you own a power planer? (I'm not in the market for one, just wondering.)
No.
