Thread: Ci1 Easy Rougher

Because the sharp edge is tilted ever so slightly up at the front, I'd say that it is part way between a scrape & a peel cut.

On some timber, particularly the wet Hoop I used it on, the shaving peels off like peeling an orange.

On a harder piece that I tried, while it was cutting the dry outside of the blank, the waste came off as splinters until I got into the smoother, damper timber & then it also peeled off in a streamer.

When the tool is moved sideways with the cut happening on the side of the tool, that side is angled back ever so slightly so it is more like a shear scrape.
Again, if the timber is smooth & wet, the shaving peels off but if it is hard & dry & uneven, it tends to splinter/chip/shatter.

Scaper or not? I'm no expert but I've probably used the Ci1 more than most here in Oz.

Much depends on the timber / hardness and whether you cut above or below centre. And whether you cut end grain or not.

Like Cliff, I've had curlies stream off the tool, even on hard redgum (a timber that Craig will not know of, so maybe someone could give an American equivalent?).

But curlies are no definition or test either, as my HD scrapers peel fluffy curlies off the tool as well on face-plate work.

For me, the acid test has been with peeling cuts on between centre work, mostly on KD redgum. With a sharp insert, the finish is superb. But that goes against the grain for the pros who argue that scrapers have no use on such work.

But the Ci1 DOES well at this task. You can't argue with the finish. So that says to me that the tool cuts. I certainly can't get the same finish with super-sharp scrapers.

That said, I won't be using the Ci1 for that work ordinarily. I prefer to keep the inserts sharp for end grain work!

Scraper.

interesting from what i know of cutting implements on wood they bevel rub then you angle them a bit more to put on the cut so whit this ci1 kept flat to the work piece its more like how metal tools cut (metal lathes and the like) where they don't bevel rub but have clearance and its more to do with the shape of the tool as to how the cuts are taken. so is this sort of how they work or does the bevel rub? wait before that do they have a bevel?

Great thread, I'm learning so much, thanks for doing this Craig, most tool makers are not interested in any discussion about how their tools work.

I'm lucky in that the Yen is stronger against the US dollar than it has been in years, but, I'm so busy with other things I'd have to look to find my bloody lathe

Cheers!

I would be happy to call it a scraper type tool, Craig!

It takes no skin out of anyones nose, what type is, really...! is no less "value" on one than the other, all have their purpose, now does this type tool does what is intended to do, remove large quantities of timber, of any timber, very quickly, so called timber roughing? yes, it does, and it does it better than any other tool I've seen or tried so far (considering that I haven't used an original, yet!), maybe one day...!

Cheers

wow this tool sounds very good i don't know if id get one (money troubles ) oh just to clear up confusion, when i asked if it was a scraper i didn't mean that its any less of a tool i simply wanted to know how it cut. thanks for answering my Q's and all the best with your product

Where abouts in Queensland are you? (bloody big place)

There is one floating around that you may be able to test drive.

robutacion,
You are right, at the end of the day it makes no difference (to most people) wheither it is this cut or that cut.

It would be nice as a craft though to get a firm definition on many woodworking terms, such as types of cuts.
I am NOT saying this should be solved on this forum and really have little interest in going any deeper into the subject myself, at least for a while. Just thinking about the new folks getting up to speed more easily.
