Re: Scrub plane recommendations.

I made a wonderful scrub plane out of an old Danish horned woodie. This had a blade that was 1 3/4" wide and 1/8" thick. The old Euro woodies are typically constructed like this. Look out for one.
The important points for consideration are:
(1) a woodie is not only lighter than an iron plane (such as a #40), but glides over timber more easily.
(2) The blade needs to be narrow, about 1 3/4" (same as #40 or a #3) is much better than a wide(r) blade, which requires more effort to push.
(3) The thicker the blade the better. The thinner standard Stanley blades (like your #5) will flex under the load.
While you can radius the blade freehand, I made up a jig to do so on my high-speed grinder. Just a piece of timber the same size as the blade, one end radiused as you require. Screw this to the blade, extend as far as necessary for the desired bevel angle, and then use the curve as a template against the grinder's rest to steady and shape the curve.
On my blade I aimed for a 3" radius, which was approximately 1/8" (from memory) down at each corner.
I hope this helps (and my descriptions make sense)
