fitting the mushrooms

[K4KEV]

If it has been turned to the correct specs then it should be a little tight but if it is too tight then use a drill type flap disc on the inside of the upright but only enough to make the mushy less tight or the mushy needs to be put into a lathe and a fraction turned off the main dia.....be very careful prizing the upright as with it being cast it will give no indication as to when it will break if over "prized"
