I stumbled across this video in my FB feed (which I look at, occasionally, don't judge me). It's worth watching, in my opinion.
And just in case you did not have the pleasure to hang out with the metal folks as much as I did, and are not familiar with the power hammer thing - it's a machine that replaces yourself or someone swinging a very heavy hammer to hit whatever is held underneath.
Now... if you don't have a power hammer, you can wield the heavy hammer yourself, or you could have a helper (the striker) who will hit the place on the item that you point to (by hitting it with a smaller hammer, in counter-rhythm to the rhythm of the striker). It makes things easier in some way, and different in some other - as you have to turn and place the item at the right spot for the power hammer to hit it in the right way now, instead of having control over the hammer as well now (like angling it a little bit, or varying the power with which it hits at the last instance).
You might see it a little like using an electric spinner instead of a treadled spinning wheel - it takes away the (stunningly boring) effort of powering the machine, but you lose a little bit of the flexibility and control. (Yes, you can use a pedal to adjust the speed of your machine, but I found it to be much less sensitive than my foot on the actual treadling pedal.)
For some people, an e-spinner is out of the question for this reason - they want to do all the work, not just some of it. Some might prefer the full control, while they wouldn't mind skipping the treadling work. Some might be happy to accept the changes because they do not want to treadle, or are not able to. There's always a range of individual decisions and evaluations behind that choice... if you have it.
For some people, buying and storing one spinning device is the most they can afford, and the question about which tool to use is rhetorical. In that case, you decide once (hopefully wisely to best suit your needs) and then you use what you have. If it's not perfectly suited, well, if you are familiar with the tool, it will usually work in some way after all, and you will make do. (As one of my teacher once said - "The best tool for the job is the tool that you have.")
Will I judge anyone for using a power tool? Unless it was used for an experiment where the aim was to learn about original processes, or if it was used for a reconstruction where the primary goal was to do everything as correctly and historically accurately as possible - no. Not at all. A power tool, or a modern variant of a tool, might make your life and work a little easier, and a little faster, but it does not mean you don't need the knowledge, skills, and experience to achieve a good result. Or, as the man in the video says: A power hammer does not mean you take a lump of metal, place it on the power hammer anvil, and an axe comes out all by itself.
Myself, if I am working on a project that does not require the complete use of historical means for one reason or another, I will happily go use my modern tools to make my life easier, and, yes, to make ordering such a bespoke piece more affordable for my customers. I will also happily replace original contraptions like a two-post construction to hold up a tablet-weaving warp by two modern clamps. It's two solid thingummies to tie my strings to. This does not change anything at all in the process of messing up my tablets trying to finally reproduce the pattern correctly.
If, however, you cheat for something that was supposed to be done all medievally, and you use a power drill to ply or a power hammer to forge, or an e-spinner to make yarn, well, I will definitely give you the Evil Glare of That Should Not Have Been Done.
There you go. I hope you always have the tools you need to do the job, and that you will choose wisely when getting new ones.
