Topic tags/keywords: cabinet scraper card smoothing sanding scraping burnishing

Hi guys,

First posting, but been reading the forum for a while now.
Just been getting into using the card/cabinet scrapers…. Wow! I’m offically a convert.

I have 5 of them from Lee Valley and Bahco. Over the past month I’ve watched every video on how to prepare the edge and burr. I’ve methodically tried every technique, and I don’t understand the results I’m getting.
When I go through the full rigamarole (file the edge flat, smooth the edge and sides on sharpening stones to 90 degree angle, burnish the sides, then use burnisher on the edge to make the burr) I get crappy results every time. Just some dust.

BUT… When I simply file the edge flat at 90 degrees, it only takes a few passes with some pressure, then I lighten the pressure… then it works beautifully! I’m consistently getting beautiful ribbons so thin they must be a single cell in thickness. It’s so much faster too! In about 3 minutes i can do the edges of all five scrapers, and then just go to town on my black walnut table top till either it’s perfect, or my thumbs get tired. The finish speaks for itself. No imperfections no matter how close you look!

Why is this happening? Am i missing something here? I’m ready to toss the burnisher in the garbage (metaphorically). My file is the kind with diagonal grooves in only one direction, nothing special. Anyone understand this? Why aren’t people in the videos teaching this technique?

I’m perplexed yet thrilled!

Thanks,
yourpaldan

From what I read in your post it appears that you are doing everything correctly.
Have you looked at the newly burred edges with a magnifying glass to see that you have a good burr?

Could it be, just for the sake of arguement, that you aren’t using it correctly?

To me the William Ng video taught me how to get the burr. A little oil on the burnished and the angle is only maybe 5% from 90. I also Stone the edge using a wet wood block so as not to gouge the stone. And reshaping the burr is so easy with Ng approach. On wider panels I don’t even sand anymore.

There have been a few threads pop up as ‘new’ that were originally posted (and answered) over a week ago… something wacky going on with underlying database around here for sure.

Ok, I’ll say it. Not just this, which I was positive I replied to, but some effin DW 734 planer threads. Yall see that? 4 or 5 threads on the same day about the same thing.

Me thinks DKV got banhammered but had more than 1 hinge.

If it looks fishy, smells fishy, rub it with red pepper and throw it in a skillet: it’s fish.

Ok, I’m done.

I had a similar experience and decided that the Stanly scraper I had was made of stainless steel. I now do not burnish the edge after sanding flat at all and it works well. I have a scraper that a friend made from an old hand saw that I do burnish and it also works well for me.

That makes sense… glad it’s not a buglet in the database :)
