Thread: feather to straight

The ol' Robert newsprint recommendationl........gotta love it! You really shouldn't need the newsprint following .25 diamond paste. When it starts to get close, limit your work on the Norton to a couple of 1-3's on the 4K/8K and then try only the .5 paste for 10 strokes. If really close then, try 10 on the .25. I have used the newspaper wrapped around a stone after coming off my Coticule or Escher stone and sometimes it works and sometimes it doesn't. Always worth a try though.

Try not to compare the straight with the feather too much. Those machined blades are very stiff and unforgiving. You need virtually no pressure to shave with them. Any pressure usually causes a nick. No pressure on the straight either, but the shave should feel more comfortable.

Good Luck.

0.25 diamond paste makes a nice edge, but in my hands it won't get the razor to feather levels of sharpness. The newsprint will. If the lap count if bothersome then make sure you've got a big B&W photo on the top side - that can cut the lap count in half. If that still to annoying then put a *very* small amount of 0.1 micron diamond on the newsprint. That can cut the lap count down to 25 laps or so.

Robert,
Is the newsprint lapping done with the edge leading, like honing or like stropping, edge following?
Thanks for the clarification!

You can do it either way. It's faster edge-leading but if you're gonna do it that way then it's critical that the paper be perfectly flat. It's easier to do it edge-trailing. The newspaper is very slow, so you really want to make sure you've done all you can on the 0.5 micron paddle before you get to this step.

I sure hope I get to your experience level some day. This is so much fun.

well I honed my razor on saturday before I read this post. to do the newspaper will I hone it again or just go to the .25 or .5 paste followed by the newspaper?

I found it difficult to get an even coat of the .5 and .25 micron pastes on the strop without some water but water and paper don't mix. What is the recommended method to apply an even coat of the .1 micron paste to the newspaper

I don't try to get an even coat, not even on chrome oxide - it's too easy to get sucked in to overapplying the paste if you go for evenness. I take a very small dab - about a 1mm-long line from the syringe - and smear it diagonally down the paddle at about a 45 degree angle. I apply the line sideways on my fingertip and slowly roll my finger as I rub it across the paddle to help ensure an even track across the paddle. I'll do about 4 smears in each direction (i.e. at 90 degree angles) resulting in a crosshatching pattern, then smear it lengthwise up and down the paddle as best I can. The first couple of razors you hone will smear it around even more, though you may not be able to see this because it's so thin. But it'll still work great. Using a thin coat reduces the drag and makes it easier to strop on the pastes using only the weight of the blade, resulting in a sharper edge.

I use the same technique for applying other abrasive pastes like coarser diamond pastes and chrome oxide, whether the substrate is leather, wood, vellum, cardboard or paper.

Great tips MParker, Thanks. BTW How much coverage can you get from that 1mm line of paste (in lengthwise inches for example) 10 inches of leather strop? Or would that require additional paste?

Sure. How long of a stripe you can run depends purely on how quickly or slowly you roll your finger as you apply it Again, you're not going for density - the paste can be so thin it's invisible and yet still work great.

I'll see if I can take a photo of one of my pasted paddles for illustration... hang on...

Edit: Ok. Attached is a photo of a paddle made out of newspaper wrapped around an 8x3 piece of bathroom tile. The "top" of the paddle is the bottom of the tile, which was flattened by building it up with grout then lapping it flat. The newspaper is pasted with 0.1 micron diamond applied in stripes then smeared with my fingers and later by the razors.
