Scrub plane - blade sharpening

[edmund]

Hi everyone,

Just received my L-N scrub plane. Before attempting to sharpen and hone the blade I thought I'd see if anyone has tips for sharpening the cambered blade - as I have visions of ploughing furrows into my waterstones :lol:

Any thoughts and tips gratefully received.

Thanks, Edmund

Hi Edmund

I have just posted a method for doing this . See the thread on the LV Honing Guide Mk II.

Hi Edmund,

For reshaping I use a disc/belt sander.

For sharpening I use a 600 grit diamond stone.

For honing I use a 2000 grit ceramic.

On both stones I move the blade down the length of the stone, rolling it from one extreme to the other, with the blade lengthwise to the stone.

Else I use my MK.II with the cambered roller...You can also use Derek's method of the MK.II upside down as per his post--if you have the MK.II.

Grinder and fine diamond stone in conjunction with the Mark 1 eyeball and my very own Freaky Hands (TM). It's a scrub plane; precision isn't something to worry about, honest it isn't. If you're worried about your waterstones, use Scary Sharp.

Cheers, Alf

If you're worried about your waterstones, use Scary Sharp.

Or a car-boot, 1 GBP, already too dished for other uses, oil stone.

Rob Cosman sharpens (and uses) his Scrub in his video "Rough To Ready"-an excellent view if you can get hold of a copy.
Hope this helps

Thanks all. I ended up using my Eclipse honing guide, which allowed me to rock sufficiently to sharpen the blade adequately - I think. At a 25 degree angle it sharpened about 3/32" of the bevel - will this be enough or should it be at a lower angle to sharpen more of the bevel??

I've also noticed that the blade is fairly magnetised - haven't really noticed this on any of my other L-N planes. Is this something I should be bothered about????

I've had good luck using sanding fids to sharpen a scrub. I make a wooden fid by first planing a trench in some softwood with the scrub. Then I rip it and crosscut it into several pieces and stick some self-adhesive sandpaper to each fid. I have three or four grits to get me to a polished microbevel.

This way I can secure the scrub blade in a bench vise and work the curve with the fids. Works like a charm for scrubs and any other curved blade.

Given what a scrub plane is for, I'd go higher (e.g. 30-35), not lower, and use a secondary bevel.

Agree.
