[modeleng] Re: Releasing taper

I accept what you say, Tel, but there is a big difference between a shiny morse 
taper that has been gripped in the DW spindle, equally well oiled, with a 
modicum of push and twist, and an axle and 4" journal that has been subjected 
to all the grunge associated with grass-cutting; so, whereas WD40 appears to 
have worked on the taper, I imagine that more persuasive methods had to be 
applied to your mower axle and journal.
   
  Best wishes,
  Jem

  In fact, Jem, the penetrating qualities of WD40 and it's clones is not all
that good. A recent experience trying to pull a mower drive wheel off it's
axle pointed this up to me. After soaking the offending axle from both ends
of the 4" journal overnight, when I did finally get wheel and axle apart I
found the WD40 had penetrated no more than 5/16" each end.
