I struggle to get a good edge on my cabinet scrapers, will I be able to put a bur on my scrapers with the T4?

Hi John,
if we're talking about the same type of 'blade-only' cabinet scrapers, I'm afraid you can't use the Tormek for the burr.
Usually the scrapers' old burr is removed by grinding, and a new burr is raised with a solid piece of steel, round or triangular. (I think it's called a burnisher.)
So I'd say you could use the Tormek to prepare the scraper, but not for raising a new burr. Yet I don't know if that would be better than using a file.
If I misunderstood the term, just forget the above :)

Burrs on scrapers are indeed done by turning the edge over with a burnisher made from a material that is significantly harder than the scrapers themselves. The edge is usually ground straight and flat, before applying the burnisherhttps://paulsellers.com/2015/02/scraper-burnishers-that-work/ (https://paulsellers.com/2015/02/scraper-burnishers-that-work/) to turn the edge over in a couple of steps, first to turn it a few degrees. Tormek can be used to prepare the edge, instead of using a file. If you still can't get a good burr, you could try grinding the edge for a 45-degree bevel before burnishing it.

I should have said "good edge" before putting a bur with the burnisher.
OK. I thought I saw a possible setup for the intended purpose here in the forum, but can't find it now.
This video: https://www.youtube.com/watch?v=yyp_sxp3OmE shows that setup around 1:16, using the side of the stone.
That works great. I sometimes use the Tormek for squaring the edges, but still carry a file with the (straight) blades and the burnisher. The first method requires a Tormek :) , the latter a bench or vise and some scrapwood to fix the blade, which is helpful for burnishing, anyway.
