Hi all,

I know this has been discussed before, but without clear resolution.

CPR does not offer a trim kit to cover the 3/8" un-painted edges of the reproduction backglasses that they sell.

The backglasses are beautiful ! Really nice work, but edge treatment is desperately needed.

I have numerous sets of translite trim for standard translite glass.

I have never had trouble installling trim and a translite.

None of the standard trims fit correctly on this glass. It seems too thick for standard edge trim.

People have successfully installed top trim and lift channels, but always lay off the side trim and consider it impossible.

I have ordered system 11 trim from pinball life and it may be exactly what is needed even if a little friction tape is needed to secure it.

I also ordered wpc-95 trim.

Ill know more when it arrives.

The problem is the rib/ridge inside of standard trims to allow for a translite.

The rib/ridge is not needed in this application.

I have 3 of these backglasses that will be installed at some point.

What is the correct trim to install that will cover the edges and eliminate the light bleed that ensues?

I just received this as the current CPR funhouse glass. $269.00

Some kind of edge trim might cover it, but its a lot of unpainted edge I agree, I was a bit surprised by it.

I have 4 different types of trim, none of them fit correctly and splay out a lot due to the thickness of the glass.

Its disappointing to see the huge area of inpainted glass at the edges.

I dont know it this is correct for CPR glass or I have part of a bad run?

So, Im taking it to pinside for solutions.

I also ordered a IJ and a TAF glass for future projects.

I hope that there is a solution as this glass is quite expensive.

yes, waiting for a response.

meanwhile I ordered these trims from pinball life:

https://www.pinballlife.com/backglass-top-trim-williamsbally-wpc-95.html

The pictures show that there is no ridge inside to adversely affect installation like the ones I already have.

But one never knows what they will get these days

will do.

If the trim has a rib or ridge inside it wont fit.

I have lots of trim and none of what I have fits at all.

Marco is great as they have actual side views of the trim.

WPC-95 trim looks good, I ordered some. as well as some system 11 trim.

I also ordered a 1/8" metal lift channel as it had no internal ridge.

I also have friction tape to help any trim that fits too loose.

I ordered that as well as another one.

They will be here in a couple days.

Ill post the result for others to see.

Here is a full picture

Should look great with the right trim!

My stainless trim arrived for the lift trim from Marco.
I think Im going to use it. Its way better for supporting the heavy glass, the edge doesnt bend as much under weight.

Still waiting for the system 11 trim from pinball life.

I got the system 11 trim today.

Its the perfect fit!

So, its definitive.

Get the system 11 trim.

It has no ribs going down the inside.

Its the perfect size.

No hammering, no stress.

It covers the clear edge perfectly.

The CPR backglass is way thicker than regular 1/8" translite glass.

This is why regular "ribbed" edge trim doesnt fit right.

But the glass is slightly thinner than 3/16" backglass.

So, the system 11 trim fits perfectly but not super snug, yet it stays on ok.

I added 2" long strips of friction tape to the center and ends of the lift channel.

Its super snug and perfect.

The sides and top trim could also use some friction tape but its just not necessary.

The tape slightly distorts the edge trim. However it makes it super snug.

This does not happen to the lift channel when tape is added.

Im leaving the tape off the sides and top trim for now unless its a problem down the road.

The CPR glass is amazing.

Im just surprised that they dont offer the trim for it when you order it.

People shouldnt have to experiment, it should be definitive.

Now it is.

CPR Thomas, responded to my email and said that its normal and that the trim covers it, which is correct..

The image is reduced slightly. It doesnt go all the way to the edges like the translite did,

I bought 2 more backglasses, but havent looked at them yet to compare more or less gap.

I think others have stated that there is a 1/4" or more clear edge that has to be covered with trim.

There are registration marks on the clear areas.

Can anyone else, who might have purchased a glass recently confirm this?

Either way, the PBL system 11 trim is perfect.

I have to agree with a lot of this.

However Im actually very pleased that the backglass is thicker and a LOT more durable than standard 1/8" translite glass.

I think they made the absolute right decision on this.

It does pose a trim problem, as there are a ton of choices for very specialized purposes, but just use the system 11 trim.

Its perfect.

I would just tape off the edge and spray it with a little krylon if its that tight.

I like to put three 2" pieces of friction tape on the lift channel.

One in the center and one near each end.

It makes the lift channel rock solid, although I did have to smack it on with a wooden mallet.

Ive "been there and done that".

Its what started me on this journey.

I have 4 CPR backglasses and couldnt get the first one mounted at all, lol. Near impossible.

The links above take you to the correct trim.

The pinball life system 11 lift channel and trim fits perfectly.

Yeah, the lift channel needs the friction tape.

After applying three 2" pieces of tape its rock solid.

I ordered all of the trims from marco and pinball life during my investigative tests.

CPR backglass is thicker than the regular 1/8" translite glass.

Its in between the regular 1/8" and the 3/16" glass.

This is why the 1/8" trim fits too tight.

It also has to be without ribs or flanges.

Just use the system 11 trim from pinball life and you are good to go.

Sorry to see that.

Its somewhat known that digital printing on glass is still in its infancy.

Printing on glass without a bonding primer is crazy.

I just dont think that there is a good primer thats perfectly clear for glass.

Even the primer for plastic on cars dries to a milky white color before painting.

So, for the moment, digital prints on glass will probably fail as we are seeing now.

Charging people for experimental procedures is a part of pinball sadly.

Put a 30 day warranty and be done with it (Stern).

Blaming a county? Thats just stupid...

It would be better if CPR would allow someone in AU to print them locally.

Maybe that could be made to happen? It would solve so many problems.

Lol, yeah one can only hope.
