BYXCO Manticore or SharpeningSupplies Double-time SIC bench stones to flatten coarse bonded diamond stones?

[scottc3]

Title says it all. Looking to re-purpose one of these, though I will be getting the Manticore anyhow for training freehand.
Manticore extra coarse 8" x 2" and 260 micron / FEPA F60.

Micron for the much thicker 10" x 4" course side of Double-Time Silicon-Carbide (SIC) -which was designed for flattening water stones- is 120 grit. I surmise this is a shop flattened dual sided Norton Cystolon Stone 120 /320, as fine side is 320 grit?
If I could rough up coarse side of Double-Time stone with 40 grit SIC or pool filter sand would that make that slab rough enough? The attraction is it would be it is a nice big stone and it is flatter then back of a piece of tile.

Looking at Mr. Wizard's Gritomatic chart and thinking about Konstantin for Venev, and Diemaker's flattening advise (for his coarse bonded diamond stones, both Columbia George and EdgePro form factors), makes me think both stones might not be coarse enough for my Venev first gen bonding on the 60 grit-225 micron and 80 grit -180 micron grit KME stones.
Historically, I have never flattened any stones, just replaced them... of coarse bonded diamond's are a horse of a different color.

The Manticore is not formulated as a flattening stone. It's an ultra-coarse stone for rapid bevel forming and repair, and will not perform well in contexts that it wasn't formulated for.

Thank you for the info on the Manticore. I'm going to pair it with a finer stone for training freehand sharpening to the boys.

It's "coarse."

You'll probably want at least a medium grit stone to go with it rather than jumping straight to a fine. The Manticore is only a 60 grit stone, which is considerably coarser than most stones on the market.

Correction edits made... I was consistently wrong ...

Yeah I need Norton Crystolon 120 /320, along with your American Mut medium/coarse since we are getting Manticore.

This morning, David from Sharpening Supplies in Wisconsin returned my voicemail from Friday. Some folks report using their Double-time flattening stone to good effect with other then water stones, unspecified. I'm not gonna get a rougher surface on the 120 side, so it would be an experiment with my finer Venev's compared to loose 120 SIC... not sure we have some still, need to look.

Also we are going to mod plastic on bottom of Sharpmaker to hold appropriately sized coarse/medium SIC rectangular stone. in addition to the dual rod slots.
