One step forward, one step back...
To make the acrylic sheet, the ufo assembly needs to come off again..

Tough stuff to work with if you don't have a laser

Acrylic sucks man!

#1458 7 years ago

This will work really well

The acrylic playfield protector is ready, it still has protective layer on it

The acrylic makes it nice and shiny

#1463 7 years ago

So the left side is the ufo shot and if you shoot to the right , through the monster, you enter the backboard shot which represents the rollercoaster ride from the movie and extra ball will be collected there,but only when you have all 4 yellow targets lit.
That is the plan for now.
We owned a " jolly park" from spinball a few months back...that inspired us for the acrylic layer over the artwork.
Simply indestructable

Here with the shiny acrylic

#1465 7 years ago

Have you tried using a jigsaw plastic cutting blade for the plastic? It should make it easier and cut clean lines. You can also use the dremel sanding barrel bits to trim it further.

#1466 7 years ago

Yeah we used the dremel, it worked okay.
But it is still a lot of work

#1467 7 years ago

You guys are soooo committed. Or you should be committed. Can't decide.
Such a fun thread and you are entertaining people all around the world. Awesome stuff.

LOL we are for sure balancing between the two
Ironically, our second machine will be "Crazy Mansion" and indeed inspired by an insane asylum.
So i am afraid we bend to the crazy side a little..

#1469 7 years ago

Just out of curiosity, How long did it take to cut that acrylic?

#1470 7 years ago
Quoted from Bonnevil69:

I bet we spend a good hour on it,this acrylic cracks easily in the wrong direction and it is ruined.
So we took our time,slowly.

#1471 7 years ago

Acrylic/plexi cuts very easily with a hand held jigsaw. They sell blades specifically made for acrylic, but a metal blade works fine too. The trick is to clamp it and keep downward pressure so it doesn't jump around. I have an art framing business and usually use the table saw and a composite blade for square cuts. The edges sand down by hand pretty quickly to get it to a point where you can polish.

Ok thanks for the advise,we want to make a big acrylic sheet for the big playfield too, so we will use your advise.
We want the playfield to last,our jolly park pinball was still in excellent shape after all these years.

Why not clear coat? I think acrylic will scratch very easily?

We have gble, if stern can't do it right, we will screw up for sure.

Haha point taken!

If you have cell cast acrylic available it's much easier to machine and cut

We bought this sheet at the hardware store, we vacuum form it, saw and cut it.
Quite expensive but not the best stuff out there.
What is the retail name for cell cast acrylic?

#1478 7 years ago

Never heard it called anything but cell cast so don't think it has brandings like extruded acrylics do

A lot of the material I get for framing is this Arcylite brand, most often OP3. Your regional distributor will probably only sell directly to you if you have a resale certificate, but you can buy the material from an art framer or some other type of fabricator at retail too. They will probably cut to size for you at minimal cost.

I pay a little less than $3.50/sq.ft. for OP3.098 (about 1/8" thick). You might not need UV filtering stuff.

Using sharp tools and moving slow you should be able to drill and cut it however you want.

#1480 7 years ago

Oh yeah check out that link- OP2 is the cast stuff. Might want to do some other google searches as there is a lot of other info out there.

#1481 7 years ago

There are two types of transparent/clear acrylic. Cell Cast and Extruded. Cell Cast is made by pouring liquid plastic between two sheets of glass. Extruded is made by heating plastic and pushing it through a slit. The result is different cell structure and at least for me (I do vacuum forming) the Cell Cast cannot be vacuumed formed (Well maybe in a big dome)...at least not in detail. So if I want to vacuum form acrylic it must be extruded.

Your will find lots of colors in the Cell Cast and limited colors (and availability) in the Extruded. Any plastic store/supplier knows (or should know) the difference. There is a store here in Seattle that sells acrylic and the colors are only Cell Cast and their clear is only extruded.

Thanks guys,very useful !

+1 for Arcylite. the other thing to look into is once you have everything measured correctly, getting the pieces laser cut which would give you precise, clean lines and a perfect fit.

I've been using ponoko.com. I believe that they have a couple of locations in europe, so everything could be cut and shipped within your region and the costs pretty reasonable

Yeah, to manually do this really stinks, we need a laser!

We have to drill the playfield and the acrylic at the same time, bit tricky as it tends to crack

Dick has a phone that makes way better pictures than my low megapixel iphone 6 , every now and then we use his pictures

These things are in the way for the upper playfield, we'll figure that out later, for now we have clearance on the space killers boot
