Flip Board Maker... anything like this available?
« on: August 27, 2021, 15:42:29 pm »
I stumbled upon this interesting technique for proper aligned two-side operations...

https://www.instructables.com/Flip-Board-Maker/



...It looks interesting, I never liked the "alignment pins" way...

Do you know of a script or plugin that can do the same on CanBam?

Stefano,
In my opinion, that design wouldn't work.  Try 'flipping it' in your mind.  When I did, no matter how I oriented it (once flipped), NONE of the fingers of the work-piece would fit in the slots of the base board.

At least, that's what I 'saw' when I envisioned flipping it.

Lloyd,
The fingers don’t align with slots when flipped, the fingers touch each other. This removes the cutter gap when flipped. The problem I have with it is that the cuts would have to be much more accurate than a couple of pins to get the same location accuracy.

Just two pins (broken cutter shanks) along X or Y axis and flipping works like charm.

Gary,
The way I saw it, the workpiece would have to sit atop the alignment board, instead of dropping down into the same spot it was when 'right side up'.

Hi Stefano
A long time ago I was supposed to compile this plugin see here:

******************

It does look interesting. I will say this. If precision is secondary, then by all means use this method. For me, the locating pins (tooling pins) as we used to called it the way to go.
 But, each its own..

Hallo Lloyd,
tahnks for your reply!
It does work, I tried this technique a couple of times and a can confirm.

You can see this in action on this video for example:

Thank you Armando,
but the script I linked is supposed to "make" fingers that don’t align with slots when flipped, the fingers touch each other when flipped.

Sure, I don't want to blame the "locating pins" way to do this sort of things. If everyone use it, if it is the "de facto" standard, well it is because it is "the best way to do it".
But at the same time I love to experiment, try others way, learn from mistakes, and I write here because, moreover, I like to learn from you all.
Do you mind to explain to a novice like me why do you state that precision is not achievable?  :o

Thank you!

That didn't even come close to properly realigning the work, when 'flipped'.  Perhaps that's 'close-enough' for a wooden spoon, but not for anything more critical.

And it would 'work' with only one specific diameter of tool.  If you change the tool diameter, you also have to change the amount the tabs 'zig-zag'.  (Yeah, I understand the software does that for you, but with pins, you never need to change anything.)

You really should check out alignment pins.

:D :D :D
Sure, I'll already use alignment pins, and I'll keep using them.

...and since this thread has evolved in "Reasons to not use the zig-zag technique"  ;) I'll add another consideration against it: it's way way slower than using tooling pins.
