Thread: Dmt 1200 for setting bevel

6 months.i use a lot for set a bevel. i bought same time dmt8000 and it is almost in new condition. i don't use it very rare i may use.aa

Referring to DMT (Dia-Sharp) diamond plates here...... I started out with the 325 to lap my Nortons and what have you. Shortly thereafter I bought the D8E 1200 to set bevels. I did find that the plate caused micro chipping on some razors but not on others. I had 'broken it in' by rubbing it down vigorously with the shank of a large Stanley screw driver. After awhile I took it to work along with a couple of Nortons and figured I would hone on my down time and the 1200 could double as a bevel setter and lapping plate.

I'm not sure how many times I lapped the 4/8 with it but I started to notice my Norton would have a gray residue left on it after I lapped it. Around that time it came out that Dia Sharp recommended lapping with the D8X or coarser. Up until then they had said the D8C was cool for waterstones but the old CYA came into play.

Anyhow, what I am doing now is lapping with anXX for an initial lapping and then going to the C. If I feel like I want to smooth it out even more I give it another pencil grid and wipe it off with the D8F 600. By then it is flat enough that the 600 isn't sufferring too much and I haven't broken the XX or the F in at all. I'll let the waterstones do that.

Meanwhile since then I don't lap with the 1200 at all. What lapping I did left it cutting but less aggressively so that it doesn't cause micro chips and it is still a fairly quick bevel setter. I'm glad to have the Shapton pro 1&2k to follow it if necessary or to use instead of it. That's enough out of me.

I have several 1200s that have received pretty heavy (almost daily) use over several years each; one for over 15 years. None of them cut as fine as my 8k EE's.

Was your 1200 ever used for lapping slurry stones? Will it still cut or "frost" the edge of a piece of glass? If the diamonds were never undercut, I would guess a defective unit.

i never used this one to anything else except for razor's. i killed first one and then i bought 2 more. this is second one which is i am talking about. i don't know it may be defective can't argue that but this is what i am seeing.
i tried it yesterday again to set a bevel just get tired of using it. i stop it and turned to norton 1k and job was done in less then 5 minutes.

I use the Norton 1000 also------
