Mr. Stickler: Yes, I meant .02mm/turn. The mechanism has a total range of 40 turns or .8mm, designed originally to accommodate the range of cane thickness worldwide described in Ledet's book ' Oboe Reed Styles'.
Used to adjust sidewall thickness it is easily possible to crash the edges of the cane stops, but the adjustment is so slow that one would have to be careless to do so...
The known .02mm adjustment makes it easy to try something new and to return to your known starting place in moments rather than hours
H.F.: The machine can be set up to your specs, but is essentially the same machine in any flavor. The adjustments work identically side to side and up and down. The difference between single and double radius gouging would be the user's choice of bed/blade&guide radius, since the adjustment will accommodate more than any necessary side to side change.
I am assuming (and hoping this BB will provide enough input for me to be more assertive in my beliefs) that a single radius machine will have size on size bed and blade/guide sets, whereas the double radius will have a smaller blade/guide radius which can be offset without stepping on the sidewall dimension.
I haven't spent time describing the other adjustments, but for the sake of completeness, here they are: the blade is indexed against the back wall and on an adjustable pin whose function is to accommodate blade wear as the blade changes length with sharpening, rather than to set gouge thickness or chip thickness. You would not expect to change that adjustment until you had sharpened the blade a number of times.
The front guide is adjustable so as to expose more or less of the blade to the cane, thereby giving a thicker or thinner chip thickness without changing the final location of the blade (which determines the gouge thickness). That way you can take more of your softer cane and less of your harder cane get the cleanest chip possible.
Both of these adjustments are .25mm/turn, relatively crude compared to the fine adjustments, but
