I have a Reliance Barber hone with a grey and brown sides. The description indicates that the grey side is silicon carbide. This grey needs lapping. I was wondering if I could use silicon carbide lapping compound and a glass plate (i.e. using silicon carbide to lap silicon carbide)?

Another alternative is a diamond stone (1200 grit) www.leevalley.com/wood/page.aspx?c=1&p=33005&cat=1,43072
Any ideas?
600 grit wet/dry sandpaper on your countertop. Do figure 8's or X's.
I lap about 20 stones every week and I use a DMT Coarse continuous diamond in the kitchen sink with a warm stream of water carrying away the swarf. The DMT is a quality tool and will give you consistent results for years.
Sorry - Newbie alert
What is Lapping?
thanks

So do I stick the wet/dry to the surface and rub the hone over it or rub the wet/dry over the hone?
I'm guessing there is actually a difference. Does it matter?
Stick the wet and dry on something flat like a piece of glass, tile, I've even used concrete/pavement at a push. There used to be granite dump near me and I have used polished/faced granite from there in the past.
This tends to embed grit on the surface of my Norton 4k/8k, do you run into this at all?Quote:

Just to confirm, are you sure you're using Wet/Dry sandpaper?Quote:

Only the first one or two times I did it. This seems to be a reasonably common occurrence for new nortons judging by the comments on this forum. I don't know if there's a sealant on the hone that is causing this or what. It's been a long time since this has happened to me.Quote:

I've got a reddish 3-line Swaty - both sides of the hone are extremely smooth - such that, when I put some lather on it, the razor just slides like it's on a piece of glass - no evidence of any cutting action.
I was wading around in the archives (ah-ah-ah-CHEW!!!)(excuse me - dusty in there!) and I found this:
http://straightrazorpalace.com/image...ize/Swaty2.JPG
down in the lower right corner, it makes reference to
"5. Should the rougher side with long use get too smooth, rub it when dry with rough emery paper or with a flat piece of pumice stone and plenty of water.
6. Should the finer surface with long use get too smooth rub gently with fine emery paper."
My question is the reference to a 'rough side' and a 'fine side'. My Swaty seems to be made of the same, reddish-brown material throughout, and both sides look and feel the same, i.e. smooth as glass. The only difference is that one side has the makers mark, and the other side is smooth (I use the back side for honing - the makers mark takes up too much real estate.)
So-o-o-o-o, my questions are:
A) Did Swaty make a 3-line, 2-grit hone, or are all 3-line Swaty's the same?
B) Does my reddish-brown 3-line Swaty in fact have 2 different grits, and I'm just too ignorant to tell the difference (entirely within the realm of possibility)?
C) Is my Swaty too smooth?
awaiting your replies with bated breath, I remain, as always.....
....here to serve.

Your stone is glazed. Scrub it with 1000 grit wet/dry sandpaper or fine emery paper.
IIRC the back side is the coarse side and the front side is the fine side, but I can double check when I get home. The material looks the same but it definitely doesn't feel the same when you're honing. I don't think there's a huge difference though.
Sandpaper grit has ceased to be a problem for me since I started using Keith's stuff from Handamerican. I think it's even higher quality than 3M.Quote:

Thanks :tu- I've been using mine for a couple months, now, and had no idea that there were two different grits! duhhhhh!Quote:

Yes you can lap silicon carbide with silicon carbide (shorthand is SiC). You could even rub two stones together and get them flat... eventually. My daily practice is to lap on a DMT continuous diamond Coarse stone under running water in the kitchen sink. The DMTs are very flat and will flatten your stone quick quick. I do 20 or so stones a week like that.
