It's more upright, and your weight is further forward. (some make them with out the bevel) I made a quick mock up using 3x2's and then measured the angle.

compass plane

I've alway known it as a flexable sole plane. this was give to my by my Dad (89) who was given it by his foreman when he was an apprentice

Thanks, the back is 115cm tall from floor, and the top of the slot is 28cm from floor and 20cm wide, the total length of the slot through is 120cm with seat being 34cm front to back. (all approx give or take 0.5cm)

15 degrees, it works for me.

Thank you. Sir.
