Chain morticer - Ryobi CM30

[Andy Dingley]

Anyone got any experience with chain morticers, particularly the small Ryobi?

Should I buy one that's going cheap ?

Sorta like a tiny fixed position chainsaw.

You know what a mortise is ??? You know what a chain saw is ???

And while you're there click on the ProtoTools image and have a look at a 16+ inch hand held circular saw!

The contractor that did my house addition used one to cut a big beam for the ceiling. At the time I'd never used anything larger than my 7 1/4 worm drive SkilSaw but I knew enough to stand way clear of that beast. The kick from the start up torque was scary enough but the sound it made after spinning up to speed wasn't just gut wrenching (sp?) - it was sphincter clenching!

Imagine a kickback where the board stays put and the saw AND operator gets thrown. THAT's a scary tool.

I don't think "timber framing" is for the "faint of heart or "the light in the ass" category.

I went to a Timber framing class a few years ago

and they had both the chain mortiser and 16" saw. One of the two had been refitted with an1/2" magnesium plate that eliminated the starting kick completely. The difference was enough that most of us would wait for it after using the standard saw one time. And the chain mortiser was lots of fun. Joe

I think kickback with that saw is pretty unlikely. the large diameter blade is being turned by a motor about the same size as a skil 77. the amount of torque at the tooth can't be too high. it *should* be pretty easy to stall....
