  It’s an early model of a razor scooter. For some reason it wasn’t popular with the kids.

  Here is one.

  Not a, "what is it?".

  Just a, this is what it is.

  You don't see them everyday.

  Most blokes have seen hand woodwork planes that are used to TRY and make bits of wood flat and square, like the ones in first pic.

  But what if you want to plane curves?

  Well this fucker is just what you need.

  It is called a compass plane and was included in a second hand Patternmaking tool kit I bought doing my apprenticeship (1980), from a just retired guy who worked for the N.S.W Railways Foundry in Sydney.

  By turning the dial the arrow points to in the next picture you can change the base of the plane to any diameter curve, convex or concave you want.

  Just posting for general interest and perusal.

  So it planes both inside and outside curves FC ? 

  How are you supposed to hang onto it without getting blisters on both hands?

  When you screw the adjuster from outside to inside does it go with a jump?

  Yes it does.

  Pretty much like a regular plane. Blisters do not usually happen.

  No. No jumping. (No Jumpers, Jacks, Sweet Mary Jane)

  Well if we must be technical then you are correct Hoodeng.

  Spokeshaves as the name suggests were really for making square (spoke) sections into round ones.

  You know, aerodynamics of wheels and spokes on horse drawn carts was very important back in the day.

  Compass planes would have been more suited to the wooden rims.

  Those "power bomb" exhaust bulges have been around for a fair while. On a YZ450F which we had developed quite a lot, we had one crack. Cut it off and welded up the holes. Bike actually ran better, it was a very small amount, never find it with the butt dyno.
