Well I guess I'll have to "tap" all day then, ay?

Then you're hitting it too hard.

Did not...

Put down the big mallet. Get a small, light hammer (about 4oz) and tap
it _quickly_.

I did exactly that.

It may take some goes, but I've never met a plane this
wouldn't unstick unless the iron was actually rusted in.

That's reassuring

If you're recovering a junker, then you may need to be brutal to the
wedge. But this is very much a last resort.

No, as I said they're both new.

Making new wedges isn't that easy either -

Not needed.

Thank you Andy! Really appreciated! A great answer of help. CHEERS!
