I was advised by a member of this site to do it in the following manner, which is what I did. Get a piece of 15mm copper pipe about 6 inches long; hold the end over a flame to heat it (in my case I used the gas hob on the cooker); holding the other end of the pipe with a rag or similar around it as it gets hot; then, having secured the acetate sheet on the backboard, pierce the acetate with the heated pipe through the holes. I would imagine whatever method is chosen it can get a bit tedious but worth it in the end. I used a panel pin to make the screw holes.

Perfect!
Looks so much better and it works now, which is a big bonus. Quite easy to do once you start - leather punch kit is man's best friend.
Thanks to everyone who helped.

Top Job there will be no stopping you now..lol.

Too right Stu.

It's amazing how much dirt there was under that old plastic and how clean it came with a bit careful cleaning.

Does anyone know where I can get some plastic sheeting that would be suitable for cutting and making a new backflash for a Defiant allwin?
This sort of stuff:

Thanks.

Never thought of painting it.
Thanks mate.

I am finally getting around to putting a new backflash on my Bryans Fivewin.

As you only get one chance at making the ball release hole in the backflash, before making a mess of it, can anyone recommend a tried and tested way of getting the best result.

I intend firstly to glue the backlash in place, then when dry to cut the holes.

Any advice out there greatly accepted.

Put a light behind it to locate it and use a pin to pierce through the outline.
Tidy up with a hobby knife.

I'm not sure why you want to glue the backflash. The fittings should hold it in place perfectly adequately. Bowing and warping of old plastic flashes was caused by expansion, particularly when machines were operated outside in direct sunlight. Had they been glued, I think the plastic would still have moved, tearing off the underside graphics.

I would not advocate gluing the flash for one very good reason. The solvents in most glues will dissolve either the backing layer and possibly the colour layer. I would follow pennymachines' advice. I used a sharp flat wood bit to cut the hole on a very slow drill, having tried a hole punch, which simply split the plastic.

Thanks for the information.

Hi all,

I'm attempting to make one decent machine (Whales - Win a Kit-Kat) from a complete door and a "butchered" complete machine.

I guess I have all the bits to finish-up with one complete machine but WHERE TO START!

I am currently working on a new backflash, but how do I position it on the existing fixing holes and what is the best method of cutting the holes for ball release/gallery.

Any advice will be much appreciated and let me know if anyone needs the file of the backflash when it's done.

Thanks in advance. M_ick

Coincidently we were talking about this very thing less than a month ago .... (now merged above - Site Admin.)

I like to use a dremel style sanding wheel to smooth out the allwin ball entry/release holes. Either used in a Dremel or just in a standard hand drill. The sanding wheels are slightly smaller than what's needed so after drilling a pilot hole from the back of the artwork you can clean up and make sure there is no lip. Looks pro.

Assuming you're starting with clear plastic - hold it in place while you mark up the holes with a non-permanent marker pen. Otherwise, use a piece of tracing paper.

I'm sure it will prove useful if you upload it to Resources.

Hi everyone I'm currently restoring a large case B M Co. 24 cup allwin. I need a new backflash. It's red and a thinnish plastic like material but I don't know where I could get one from. I have brought some red card close to the colour and was going to have a play with getting one laminated and one sprayed with clear lacquer as a trial and error. I hope someone can help and give some advise please
Regards Dave.

Hi Dave, have you tried searching "backflash" or "back flash" in the Resources section of the forum?

I haven't done yet as I'm relatively new so getting used to how it all works, will have a look now thanks

I'm not promising you'll find what you need, I know there a few in there but I don't go out of my way for allwins.
You might need someone who is into BMCo and can photo one.
But it's worth a look.
