But knowing the right tool, including the tool's durability and reliability, directly influences your abilities. I find acrylic work to be some of the most exact and precise work you can do. Its not like cutting wood where you can simply fill in the cracks and mistakes with putty, or just cut another because the material is cheap.
While I am not saying that owning any tool determines your skill level, to deny that the tools abilities directly effect the craftsman's output is like saying that a marksman's ability with a rifle isnt affected by the quality of the rifle...as then skeet shooting would be done with 'sawn-off' shotty's and sniper rifles would be replaced with pistols.
When that cheap tool breaks or ceases to work (or heaven forbid, injurs someone), I would call that a direct effect on someone's craftsmanship. Otherwise, if a cheap saw worked as well as one 5x the price...why would the more expensive one be sold? Come on guys...there MUST BE A REASON.
I started out with some 'less than adequate' tools. A ryobi drill, an old table saw, a radial, and a DIY router table with an old underpowered router. I couldnt make an acrylic tank with those tools to save my soul. I would be better off with a hand saw. When my uncle first offered to cut acrylic for me, I asked him "whats the tolerance on the precision?...how much will the cut vary?...l.ike a 1/16, 1/8, 3/8?" He said "None". I said,"come on...no really"...and he cut the acrylic. Sure enough...it was as straight as a ruler...and not even a chip in the plexi. I didnt have to go back over the cut with a router or flame polish even. That wasnt skill, that was the machine.
Of course, if craftsmanship depends only on the craftsman, then all the automated assembly lines should be replaced with human workers. Yeah, right.
You must admit, its a combination of both the user's skill and the quality of the tools that determines the output...one depends on the other. At that, if a certain tool is all a person needs for a given application, then thats all that matters.
For acrylic work, I would use at least a 4' fence and large surface to keep the acrylic flat and stable. The accuracy of the fence is mort important. Now, if you go and put a $300 fence upgrade on a Ryobi table saw...fine (as long as the blade has a good arbor system that prevents it from wandering). You can always luck out with cheaper tools...its just not as likely.
