Coronet major planer stuck set screw and lock screw

[GeorgeCass]

Recently picked up a well looked after Major with planer , and saw etc . Everything looks good and there is no surface rust in fact it looks excellent but last night I tried to take out the planer blades and couldnt shift either the slot head screws or the allen bolts that hold the blades in place. Thoughts ? Tips . Have squirted them with WD40 and will leave a day , Would you guys try heat ?.

Plus Gas is a much better penetrating oil. Try that first?
