I should reiterate, signs would be in wood(which I thought the 90° V bit could be handy), while etching would be in acrylic/polycarbonate.
The V tooling which we sell cuts wood quite well.

Aside from the V, what other endmill might be helpful in that area? I dont have endless funds to throw on them at the moment but, figured id try to get a few to broaden my #201 limitation.
The #251 is one of my favourite tools to use in wood, the other from our shop being a 1/8" downcut such as the one in:

That pack, plus the drag, and I’d be set then? Just to clarify, as I could remove the other two items in my cart.
I think so.
The thing is, endmills are consumable and an on-going expense — you have to budget for them (says the guy who gets them free from his employer as a perquisite (for the most part)).
Two excellent resources to learn about endmills are the Material Monday videos (linked above) and:
I used most of my favourites in:
and explained why each was needed.

Awesome, thank you! I’ve got a bit to catch up on, and excited to try out some new things. That box, is pretty freaking cool! I know I’ll be back with some questions soon, as I try to better understand toolpath settings.
I did start to get the hang of Carbide Create a little more, still unsure on a few things though, as I sketched something out in Fusion 360, and unsure how to recreate it in CC.
First pic, is a sign I’m wanting to engrave for a personal project.
Second one, however, has me stumped, on how to make it in CC(it’ll be a finger joint box, as I’ve not yet finished it).
Note that finger (well, box) joints require a vertical fixture at the front of the machine — I worked one up ages ago:
but am disenchanted, either w/ my clunky fixture, or the entire concept — cutting traditional joinery on the machine requires at a minimum 3 setups:
- cut parts to size and machine internal features
- mount all 4 boards in pairs in the correct orientation on the machine/fixture and machine joints at two corners
- reposition all 4 boards and cut the opposite corners
We’ve tried a bunch of other techniques:
and I’ve been working on various designs:
and see the pages on joinery at:
I’ve pretty much dialed things in w/
The bamboo pencil cup had joinery so tight that when I clamped it up for a test fit, I couldn’t get it apart:
which I need to finish writing up/documenting — the issue is one of balancing the size of a V endmill against number of passes w/ a V endmill — the former can be a budget and spindle capacity issue, the latter gets tedious to draw up and arrange toolpaths for (in the current Carbide Create).

Would I be able to utilze the tape and glue method for the joinery, as my stock would be .25" polycarbonate?
I believe so — it comes covered in plastic right? Put the tape on that?
It does, yes. I’ve gotta figure a few things out in the design first but, have a small sheet I’ll practice on beforehand. Is there a specific glue folks are using for this method?
We sell:
(which is painter’s tape, cyanoacrylate glue, and accelerator — I just buy glue in the smallest possible container whenever Michael’s sends me a $5 reward if I don’t have too many)

I was thinkin it was CA glue. I’ll have to snag some, as I’ve got plenty of painters tape.
