wood hardness table

[GAKnothead]

Greetings all! Have been struggling with cherry stock over the last week.  Bought a new cutter; Domino still jumpin' all over - even with the stick clamped down and the operator wide awake.  It suddenly dawned on me that it just might be the wood.  Have not worked with cherry before this.

Will somebody please point me to a chart or table of the relative hardness and/or tooling difficulty of the various common woods?  I know it's here somewhere on this innerweb, but it eludes me.  Hoadley's book speaks in generalities.  Thx.

That's because the hardness of wood within a species is highly variable.
That said, I've never found a super hard cherry so I can't imagine that the wood
is the source of your problem.

Are you mortising the face of the board or the edge? How are you holding the Domino?

Just do a Google search for the Janka Wood Hardness Scale.  As mentioned, it will vary greatly within species.

I've used the domino in cherry w/ no problem and have done quite a bit in burmese teak which is harder w/o any problem.  Does it jump around in softwood too?

I've had no problems with my Domino machine in red oak, white oak, birch, cherry, black walnut and African and Honduras mahogany, even in end grain.  As others have said, hardness varies greatly even within a species.

Thanks all.
I'm mortising edges to build up a panel with the board clamped down, hanging on to the machine two-handed for dear life.  Film @ eleven.

somethings wrong with your domino. My domino eats right through anything I feed it. IPE, Ebony, Jatoba, Hard Maple. All no problem. Cherry is one of the soft hardwoods so it cant be the wood, dude.

Edit: Im still on my original cutters and I got the domino on the USA release date. 2 boxes of 5mm dominoes, 2 boxes of 6mm dominos, 1 box of 8mm, 1 box of 10mm and countless homemade 6,8, and 10mm tenons have been used and the cutters are still going great.

Are you plunging too quickly?  My domino goes through cherry like a hot knife through butter

I'm with Jay. I just put together a cherry box yesterday with my domino. If I try to plunge too quickly, the blade starts to chatter and the machine starts to move. Plunging steadily and slowly it just glides through the wood.

Agree with the above.  Something's wrong somewhere....  Have you maybe dropped your cutter on the shop floor?

Anyhow, here's a wood hardness chart

I tend to judge the hardness of a timber by how much effort it takes to saw a piece with my Disston Panel saw ;D

But those links to the Janka Hardness Scale information are quite, well, informative! I learnt from them so thanks for the O.P and replies guys.

Glad I came by your post I am having the same problem with domino, and after reading the replies you got I no my answer.

Many Thanks
