My Pacman Shelf ...

[Jasonmm]

Hi Everyone

I always wanted to make one of these ... and boy was that a bad idea   ...



but I have no wood working skills and no tools , then a TechShop opened near me ...

http://techshop.ws/index.html

now I had tools but no skills ...

well 6 weeks later and 17 safety and basic uses classes , software classes and workshops later ...

I was able to draw this in corel draw ...

(note this is my final edit not my original)

Its a 12in 4:1 scale model ...

I could then use my corel draw file in the laser machine to create these protypes ..
I used cardboard as i have no confidence in my math and it was ofcourse free ..
Then as I grew more confident with my file I used acrylic ..

I was then able to create import the coreldraw file into the vcarve program and scale to 4ft by 4ft and set my tool paths ...
(note this file is still currently under construction )

I am going to finish this file , order my tmolding and cut the wood later this week ... to be continued ...

if you end up liking my design , I will send you my file , then you can use my math and scale accordingly ... Jason

[Jasonmm]

profile and pocket cuts ...



cutting this tommorrow !!!

woohooo !!

[elkameleon]

I appreciate your offer, but I work exclusively in SolidWorks, its a pretty simple design, doesn't look like it would take more than an hour to replicate.

[Jasonmm]

a solidworks elitist !! 

1hour , nice ...

Jason

[drventure]

Nice. Definitely would fit into a gameroom theme!

[BobA]

Nice work and may your cutting go well.

Haha, I guess I never thought of myself as an elitist, but if the shoe fits...

If corel can export to dxf or dwg, it will be a matter of few minutes to have te sldprt setup

Corel Can export to both dfx and dwg ...

yup np ...

[Jasonmm]

Update

Well I cut this out of MDF the other day and I learned a few things ... apperently the laser cutter can cut a perfect corner and the CnC machine cant ...

So the word of the day is ... FILLETS and the number of the day is 0.135

Back to the war !!

Your saying that the Shopbot can't cut a perfect corner?? Why not?

[Jasonmm]

I guess it can make a perfect corner , had I created a better drawing , I am adding "Fillets" now ...

Mike, I am now using Vcarve Pro instead of CorelDraw for the Shopbot , do you use Vcarve ?

thanks Jason

[Jasonmm]

Update

I wasnt happy with my 1st cut and I redesigned the whole file today in VCarve pro like a man !!!  ...

 ( who knew mdf board from Lowes actually callibrates out at .76 !! geeesh , thus my slots werent perfect )
 


TMolding came today ... cutting this in a few days !!

Wish me luck again BobA !!

Jason 

i was also able to export my new file to .dfx ... so after I cut ... pm me your email and I will share ...

NO you can't cut a perfect corner. with a CNC or any tool using a round cutting tool. this is half true, it depends on the side of the corner cut you want to perform.
external corner : Perfect
internal corner : Impossible, you will always have the radius of the cutting tool used.

just remember you cut using a rotating tool that follows the tangent of your cut. just draw a schematic of a square and try to fit the round tool  in the corner, you will see   

in order to have a perfect Straight corner, you woould have to use a tool of a zero dimension (impossible) that's why laser can cut quite perfect internal corners. it's much more thinner than any other tool 

[Unstupid]

It is possible with a 5 axis router and a 60 deg chamfer bit.  In fact I did one today

[mountain]

I see what you were saying now Jason. It's really only a problem when joining two pieces of wood, usually in a pocket or locking feature. I use what some call dog bone fillets. On a 90 degree angle, the tool needs to travel its radius past the angle. Here is a good example in some parts I cut recently.



Sounds like you have it figured out. Vcarve lets you choose this type of fillet. Good luck cutting.

[Jasonmm]

Here it is , in all its glory , it wasnt perfect , but it was good enough for me ...







cutting tmolding slots tommorrow ...

thanks for looking Jason

[Le Chuck]

Hey, that came out pretty slick man.  Good work.  Can't wait to see it painted and trimmed up.

[Drnick]

It's gonna sure look sweet    Do you plan on putting lots of game memorabilia on it?

[yotsuya]

Here it is , in all its glory , it wasnt perfect , but it was good enough for me ...

Jasonmm-

Looks good. Are you planning on cleaning up the edges where the shelves touch the outline of Pac-Man?

[dandare]

That looks wicked! and using t-molding is a nice touch.

[Jasonmm]

Thank You All

Saturday , I will be sanding those edges , slotting in the tmolding , and painting ...

Really      

It was alot funnier using the software .... 

 

Jason

[Jasonmm]

Does anyone know how to fix those cornors ? I dont ... I butchered them ... ugggghhh !! recut the shelfs ffs ...

I tried the bandsaw , the horizontal bandsaw , 5 different grinding wheels , a jig saw and the throw on the floor trick .... tripple ffs ...

[Unstupid]

To clean up the corners what you really want to do is recess/shorten the shelves by about 1/2" so that they don't overhang the back pacman shape and the vertical support.  However that would mean recutting the arc side of the that was cut perfectly with a cnc router.  You will not be able to recut those curves with the same precision as the router...  Chalk it up as a learning experience and recut new shelves on the router. It should be easy enough to reprogram.  Also if you are goin to be recutting parts i'd recut the middle vertical piece as well so that the slot for the middle horizontal shelf does not go all the way through.

[yotsuya]

Looks great, man!  You really fixed those edges!

[Jasonmm]

Looks great, man!  You really fixed those edges!

hey thanks , I wish I could take full credit , after 2 days of sulking , I was ready to do your plan above , but sometimes the guy at the club , working next to you , might be a professional wood worker from italy, claiming ( and I believe him cause he was hand carving a chello !! , lol ) to have made 10,000's of thousands of video poker , slot machine and video game cabs in his lifetime ...

he said "do this , do that , and becareful cause that tool is sharp" .... in broken english ofcourse ..... and they came out nicely ....

more pics to come .... painting the walll black now ...
