Well I have spent 4-5 hrs a day for 5 days and still can not find out enough information to make a Router Purchase for the table I will build. Why has it taken so long? It is because manufacturers and reviewers do not show detailed pictures and leave you hanging on features.
For instance they will say this router has an arbor lock. Big deal. That means nothing to me. Now if they said this router has an arbor lock plus two nuts that means something. Which ones do, which ones don't? Who knows.
Here are other examples: these certain routers are said to have an automatic arbor lock. "When the arbor is raised up, it automatically locks.) Well that's cool, MAYBE. No one has ever said how it gets unlocked. Does it "automatically get unlocked when it gets cranked back down? They never say. Now If one has to reach under the table and try real hard to find that lock to pull it back out then it's only partly automatic.
I personally do not want a router that as an arbor lock, unless it is an option where there is also two nuts for removing or replacing the bit. For one thing it is a misnomer. Usually they only lock as long as one keeps their thumb mashed down while pushing and holding a spring loaded lever or button while fumbling around with wrenches and bits, ridiculous. My old Stanley had a real lock. The operator pushed lever to a de-tent and it stays there until you are done. Also, while it was in de-tent the router could not be switched on. Novel huh. What happened to that nowadays? I know, unplug the router, ok, I will, maybe. Hopefully I will always remember
Another reason for using two wrenches is that I can tighten the arbor better by the opposing wrenches.
Okay all you owners out there, let's here what you got and how it works. Perhaps I/Mike/or somebody could compile a chart. Say like,
Router-------Arbor Nuts----Arbor lock-----type arbor lock
Bosch 1617= -----1----------yes-------------manual
Porter C. 892-----2----------yes-----------auto on, auto off
I do not know if these examples are accurate because I can't lay my hands on anything yet, I've tried. Big orange box store has very few routers.
Thanks for your patience in reading all of this, signed, frustrated in Utah
