This is a scraper plane I made from A Fulton 3710 chosen because it has the wide frog receiver from older Bailey styles. I borrowed liberally from (and didn’t execute it as well) as this UK example:
My ability to machine metal is more limited so I soldered two pieces of 1/4” brass plate for the frog with a 15 degree forward pitch. To cut the mortise on the front plate I made a router jig to fit a 3/8” pattern to fit my main router with a 1/4” upcut carbide bit. It cuts like butter. One difference in the UK version is that the fillister screw holes are elongated so I can effectively open and close the mouth. As I’ll explain later, that was not necessary.
The iron is a piece of 1/8” X 2” O1 steel I had in the steel bucket. No fancy machining here: I just drilled the holes, Dremelled between them did a lot of filing. The iron was oil-hardened using a torch. Safety and marriage-counselling tip for those new to oil-quenching: do it outside! The blade pitch is 45 degrees. I’ll round the corners and may draw the burr depending on how beta-testing goes but it works pretty well as is. A depth adjustment like a spoke-shave would be an improvement. For trials I laid it on the bench, slid a piece of card stock under the nose and dropped the blade until it stopped.
Back to the mouth: the nut restricts shavings getting out of the plane. I can thin it a little but may need to remove some iron off the front cross-bolster for better flow. Barring that, no planes were harmed in this experiment. You can tear this off and put the plane stock in a few minutes—no need to even remove the iron. You could also make alternative frogs with different pitches. My plywood crash dummies are in the exploded picture.
If anyone is inspired, read the UK page first. That gentleman deserves the credit. Here’s a list of the parts I used:

FWIW, the precision tool steel bars are very accurate if you need a sturdy straightedge on the cheap. sh
