[Restauration] Crazy Kong fase 2

[liquidx]

We Dutchies want 1 guilder inserts !

I've got a file for Atari one's, but now need them f.i. for my Berzerk...

I may have some guilder ones too but they suck because, for some weird reason, they're opaque and don't let the light through. Not sure who had that great idea.

You can't really print these like the atari ones, they're screened straight onto the plexi.

Since i needed the control panel to test the lately acquired PCB, i decided to create a temporary CPO
The final CPO will take some time because i need to vector that, let it print etc. etc.
First i found a piece of scrap plexi, big enough to cut out a CPO  




I did a query on some DIY fora for possible ways to cut plexi, and the advice was;
1. carve the line you like to cut and "break" it after that
2. saw it with a circular saw
3. melting with a wire

Since i dont have any equipment for option 3, i tried option 1
First i clamped a straight piece, and then i carved the plexi using it as a guide:




It dit not budge!, I jumped even on it, it would not break...
I dont know if it is because it is 5 mm plexi , or that i did not carved deep enough.
Anyway, that screems for option 2, lets bring in the powertools  




A clean cut  
I measured the cutted piece and it was long enough for 2 CPO's, so if i screw up with the holes, i have a spare  




Time for another powertool  




Also here no trouble!, a perfect round hole..
 



The temporary cp with all the holes is the result..




Because i marked all the holes in this position, the holes are perfectly accurate..




After sanding the original bolts, the are ready for painting..




As you can see i am using the famouse pattented "darthnuno mushroom painting technic"  




After the spraypaint wich i did outside, i put them to dry in the shed (it started to rain so i was in time)




Ok, lets see, i got the original stuff, and a piece of plexi, whats missing ?
Yes, a temporary print of the artwork, so i printed the scan from bela on 200 grams cardboard




To make the holes, i used the old CPO as a guide, the bigones with a scalpel, and the small holes with a drill




after assembly of the parts i rewired the wireharness




Assembly complete, including the bottomcover




Not so bad for a temporary CPO if you ask me  




Time for the coindoor resto...

great job, etienne! i've never worked with plexi before but it seems there's no problem cutting and drilling it, right?

[Belike]

You have great skills and useful tools for restorations!
Absolutely nice job!

You do need to be careful drilling perpex. Too high speeds and it will start melting. In theory you should use a special drill, but a specially ground normal drill works good too:

With my SW cockpit perspex, I was both lazy and didn't want to screw up (pretty) expensive perspex so I let my Perspex dealer (http://www.stoutperspex.nl/) recreate the bends and the holes with their professional tools. Worth every penny.

Nice work though Etienne !!! Very creative !

[Etienne MacGyver]

Thanx guys,

The cutting and drilling was no problem, exept for the smell 

Andre is right about the melting, but i did not "forced" the drill in, i let the drill do the job so there was not too much heat from the friction

also a saw with a lot of teeth is recomended, the more teeth in this case the more sharp the cut is

and also there , no force, let the saw do the work 

and the case here is that its a temporary CP, so there are also some scratches in the plexi , but they where already there since it was a scrap piece of plexi..

Looking good Etienne. And I'm glad that you finally are able to play Crazy Kong. It's one of my favourites games, I played it last Saturday for a few hours, did set the (not too high) High Score. But then again, I really sucked at DK, didn't I André!

Clean job Etienne  Congrats !!! 

[Etienne MacGyver]

Last Friday i visited Robert (the marktplaats guy) because i wanted to see wich of the coindoor covers was in the best condition.
I have a little crack in mine, and his was clean as far as i remembered, just a little damage, but no cracks.
After a close investigation i find out that unfortunately his cover was also cracked, and was in much worse condition than mine  
A big chip of chrome was missing next to the "coinslot" i guess there where many guilders that touched that part and "scraped" it off..

There was a big   after all, his had a guilder instert !, so i exchanged my 5DM instert for his 1 guider one..

its a little different than my 1 guilder inserts, but i will put it in the middle position so it does not look strange.
The rest of the coindoor was stripped exept for some steel plate wich was assembled with original screws.

I missed some screws, and Robert was so kind to donate them to me   Thanks robert !




Then i figured, its a plastic chromated cover, so why not try to polish it  
I started with the bottom, to test if it was possible using silverpolish..




Great results !, totally shiny again! its nice to have some silverpolish around the house  
 



I know you guys like before and after pics, so here they are..

Before:



After:



I glued the crack, and its drying as we speak..
im happy with the result, still there are scratches in it , but hey, what you expect from 30 years of duty 

Time to give that metalcolored coindoor also a go with silverpolish...
But not today, my finger still hurts from this polish job...
maybe i will look for a machine that does the rest of the polishing job  

[liquidx]

Look what I found in my bits & pieces. Yours if you want it.

[Etienne MacGyver]

Yes please !, kind of you to think about me !

Thankx!

this fits in an enveloppe i guess ?

Ill send you a PM with adress details.
do you have paypal, so i can transfer the postage to you ?

[Superully]

before and after pics are my favorite! that thing is shiny like hell now

[gyruss]

You are doing a great job, that crazy kong is going to shine again. 

[Etienne MacGyver]

After the pain in my hand "healed", i thought it was time to do the next step by machine.
Luckily there was a offer in my local Aldi for a "dremel clone"  
I went to the store and bought myself a nice gift..




Unpacking and inspecting time  




The extention makes it easyer to work precisely




I installed a brass brush, because there is alot of oxidation on the "coin return button" (how you call that in arcade terms ?)




Carefully i polished the oxidation away..
You maybe ask yourself; Why he dont remove that from the door? , well simple, it did not came loose, and i did not want to damage the fromt by using pliers to hold it for the unscrewing of the nut in the other side..




Time to take care of the inside first..
Before polishing:




during polishing: (yes by hand  )




After polishing..
Looks like NOS to me  




The front i did with a polish disk in the new machine.
there where some heavy scratches there, and also this side is "brushed stainless steel" so it will never shine like the inside..
Before polishing:




After polishing:
Not spectacular, but good enough for me



Time for the next step.. put it back together again..

Very nice. Euro stainless doors rule !
