Topic tags/keywords: burnisher stainless steel

I am buying a couple of Bahco scrapper – they will my first ones… I am considering to purchase a stainless steel PH2 to work with my very rare stainless screws and to use the same screwdriver as burnisher when sharpening the scrappers.

It sounds logical to me as stainless steel is very hard but perhaps I am missing something.

Your experience and advice is very welcome.

Thanks in advance for your input.

I was wondering the other day if a metal knife sharpening rod could be used.

It might work. I know some stainless varieties can gall or smear. You’ll know pretty quick if it doesn’t work. Worth a shot.

Might try to find an old Stanley #3 phillips screwdriver ( I have a couple..) the kind with the long shaft on them. Should be plenty hard for what you need. BTW: old means those older, wood handled ones. Phillips instead of the flat tipped ones, to avoid running out of round shaft. I have two that are about 8-12” long on the shaft.

I have had to make do on job sites using a putty knife for a scraper and a Phillips screw driver shaft for a burnisher. It works surprisingly well.

Like Fridge sez… give it a try and see! I’m more curious about those stainless steel screws though, and why they are so rare!

Cheers,
Brad

It will probably work to some degree – might be too soft. I had some success with scrwdrivers, drills, etc, but carbide works much better.

Thanks guys for your fast answers! Great comunity here!

I will try a Wera PH2 stainless steel screwdriver… at USD 10 it is cheaper than an “actual burnisher” and probably that German steel is harder than most of the offered burnishers.

Have all of you a great Christmas.

Yes, you can do it but probably not well.

Good Scrapers are about Rc 48-52. The shank of a screwdriver is probably not that hard because you want some ductility in a screwdriver shank so that it will bend before it fractures. I have some screwdrivers that are bent but none that have fractured.

The burnisher needs to be harder than the scraper.

If your burnisher is too soft you will not get as good of a hook on the scraper. You can buy a burnisher for about $20.

Here you can get the hock burnisher without a handle for $16 and it’s hardened to HRC 64

and here you can get a carbide one from Lee Valley for $11.

From what I’ve read, the finer the cabinet work you want to do, the more important the polish is on the burnisher.

The stainless driver will probably work ok, but not great. Stainless steels that I could find hardness data for are pretty much all under 100 for HRB which is equivalent to an HRC of about 23, way less than tool steel. There are apparently hardenable alloys, and maybe a driver would be made out of that, but I couldn’t find how hard they can get.

Have your say...
