Planing MDF

It planes fine, but I suspect this job would be easier using a router with a straight trimmer bit and guide bearing. You'll want to hook it up to a vacuum cleaner to avoid mess though.

router

Thanks for the reply. I have to confess that I've never used a router. Is this a particularly skilful job? Can I be sure of removing the excess without also cutting into the adjacent surface?

You'll want to hook

Pretty well, if you have a decent plane with a small mouth - a block plane is best, and a low-angle if you have it.

OTOH, it's hard on the iron and you'll see faster wear than timber.

If my experience of using a power planer is anything go by; no.

:o)

As long as you feed in the right direction and keep the router flat against the surface the guide bearing should ensure that you get a perfectly smooth flush finish.

router != planer

Hi Bert

Psychic MDF planes OK but knocks 7 bells out of plane irons. An 8' length shouldn't be a problem though. Use a small block plane like this excellent example

A block plane wont do the last 2" at each end (neither will router or planer), so that will have to be sanded or chiselled by hand.

Thanks to everyone for the replies. very helpful.

Dave,

Psychic MDF? Does it know what you're planning to do to it, even before you start?

thing that's not clear from the description is the width of the blade: presumably it would be fine for my half-inch edge?

I used to have (and maybe still do, somewhere) a very small plane which used Stanley knife blades. That was a useful bit of kit.

Yes, I'd worked that bit out. The bottom doesn't matter as it will be hidden by skirting, but I'll have to do a neat job on the top end.

Bert

It will plane just fine in the way you descibe, but it will make just as much mess as sanding, as you will end up with a fine powder.

I suggest u wear a face mask & glasses, and have some for of "dust extraxion"

Rick,

Thanks for that.
