Quick in Mexican time perhaps. In Oregon hours it was long and arduous!!! lol
There were two things that I found difficult. One is typical...slowing down...taking the time needed to do a proper measuring and then translating the measurments onto the block so that things were "square", meaning that the places that were supposed to be right angles were really 90 degrees...and that one corner matched the opposite corner in that same way. Getting it right before starting is something I typically have too little patience to do well. The other was translating those painstaking measurments into physical reality...via the cutting and filing of the block into the needed "pre-shape" to get a totally circular bowl and one that had the proper perpendicular rim and the canted bottom. Also, so that the shank ended up centered exactly on the center line of the axis of the bore and the sides of the shank were lined up properly. As I think I've said, I think that pipes that are 'standard' shapes, that are supposed to turn out a specific way...are much harder than doing something that's a freehand design....curves are easier than straight lines...circles are harder than following the contour perhaps presented by the flow of the wood's grain...etc. Now, if I had the right vices and cutting tools, the right angles, etc. wouldn't be so much of a problem. But as an example, once the block was cut into a square, the next "cuts" to get a 45 degree slab off was done with files. As I was cutting the briar down with the file I had to visually ensure that the resulting panel was an exact rectangle...all the way from start to finish...or it would have ended up as a trapazoid (or something) and the bowl would have been skewed off a bit. Painstaking is the term that comes to mind. At least, without the proper power tools, I have really good hand tools, so that made it OK. To do things this way you have to really LIKE doing things this way...you have to enjoy the feel of the tools cutting into the wood. ..or it would be a pain. Anyway, that's it.
