homemade mushroom adaptors

[RAYLEE29]

Hi, I made my own out of ally I adjusted some of the dims a little and I didnt bother with the taper on the top just stepped it with a radius tool.
I didnt bother with the notches either.
Not too sure if i am going to use them I might make some stainless ones as the ally ones are a bit soft.
I did mark the offset whilst they were on the lathe so its easy to tell where the max offset is.
