Hi,
I was checking out a Eumig P8 and found the internal rubber belt had gone all licorice-y.
I removed most of the bits of the belt but there has been a fair bit of 'tar' deposited on the pulleys; any tips to safely remove this would be appreciated,
John

Hi John

I use an evaporative spray on Brake Cleaner, which dissolves the old rubber bits, then disappears completely.

Get it at any large Auto Spares retailers.

Hi Frank,
thanks for the advice, you are in real danger of becoming the resident expert.
I popped along to the local Halfords who don't have the brake cleaner (I think the days of being able to seriously maintain your car using Halfords has gone).
They did sell a spray that was designed to remove tar and sap from bodywork so I bought that to try.
I'll post up how I get on

If it doesn't I have decent luck using film guard on an elmo where a belt had done that, key is to then clean with isopropal alcohol after ....before putting on a new belt as the film guard with lube the belt and cause slipping...

Thanks for the advice Dino and Frank, I tried the Halford's product, left it for about 30 seconds and then picked and pushed the rubber residue with the end of a wooden keebab skewer (basically an oversized cocktail stick), in all it took about 20 minutes. I then rubbed the grooves with kitchen paper to finally clean up.
I think Frank's suggestion would have worked better as the Halford product was probably on the mild side to avoid damaging paintwork.
Anyway the belt's on and the P8 is running quite happily again. Thanks for the help,
John

Best way to clean a P8 is with a sledge hammer!

You could be right, but it would require a pretty substantial sledgehammer - these machines are BUILT.

"these machines are BUILT"

Out of 'easy-snap' plastic. [Big Grin]

Sorry, I just really don't like P8s. I'm of the 'pinch the tranformer and chuck the machine' school when it comes to P8s.

Hi Mikael,
I've got the Novo version which has the autofeed mechanism, after initially trying this I've removed the autofeed and just manually feed.
I am curious about 'easy-snap plastic', there's not a fantastic amount of plastic, especially without the autofeed - what are the weak points?

It was mainly the autofeed I was referring to. That and the weak light and the fact that they have the Sony C-series betamax fault of almost never just working if you find one at things like car boot sales (yard sales to our friends across the pond). Great projectors back in the day but so much better was to follow...

This is all just my opinion of course.

Hi Mikael,
I tried the autofeed but the 8mm films I had fed off the bottom of the reel (a la super 8), so when I tried the mechanism the film, having the curve going the 'wrong' way, simply missed the first curved channel. So I just unscrewed the retaining screw and removed the auto feed altogether.
I was interested in trying this model having seen other members' comments. My initial impression is that it's quite a nice little machine and certainly different from anything I've tried before. I popped a new Xenophot lamp in and centred it up and think the light is quite respectable (using a f1.3 lens).
I know from reading various forums that these machines were produced in vast numbers and, because of this, I'm sure that there are a fair number that have been badly mistreated.
My experience with my one is that it has been well looked after.
Incidently Stephanie Marriot has produced a terrific little reference on their site http://www.marriottworld.com/pieces/pieces25.htm
well worth checking out.

I'm sure it is but I'll put it up against my Siemens anyday (oo-er!) Glad your getting on well with yours, I detested the one I used but for all I know you'd hate my Siemens, I guess it's a case of each to their own. Fortunately there have been enough projectors made over the years to suit most people.

My standard 8mm films look brighter on the Eumig P8 (12v 100w lamp) than most Super 8 films look on the common 8v 50 watt halogen bulb used by the silent Sankyos, Chinons that sell on Ebay for $150 and up.
