This surely must be something unique to the RM and RT machines if they get that hot, because neither my regular SSLs nor my Xenon 350 generate anything like that kind of heat.
I can flip the gate out on all of them after a reel and while a little warm to the touch, no problem at all. Never even thought twice about it.
Same goes for moving the framing lever (metal.)
I am glad they don't turn into ovens; I am sure my films appreciate it too [Wink]

I've owned a couple of NT2s. Indeed, I had to open the back to increase ventilation quite a few times. Eikis are fun and easy to use machines. Some units can be kind to film, others can be lethal. Although I've switched to Elmos many years ago, I still think that the rewind system on later Eikis is one of the most reliable when storing films on cores.

Hi Adrian,

You are, perhaps, correct.
I was referring to the possibility that it may have been lying around in a cupboard somewhere "drying out" ( for want of a better phrase!)

By the time the SSL and SNT were introduced, many of the parts that had failed due to time/materials used in manufacture had been replaced. That's why the SNT and SSL are the best choices, the amps are better, the belts are more reliable and the machines have larger sprockets and handle film better.

I'm wondering if the heat problems on the RM/NT machines which all seem to be reported by countries with 50hz power is due to the motor design on that model. The induction motors speed is controlled by power frequency and I think was designed originally for the Japan market (which is a 100volt service by the way). So for the 50hz markets, a change was made in the pulley diameter to speed up the frame rate (thus the motor turns slower, the fan turns slower and they have to handle the voltage variation for the transformer for the lamp as well).

That sounds like a reasonable explanation.

The NTs aren't perfect. Mine do get quite hot. Though the only real shortcoming I find is the racking by moving the aperture not the claw. But I made a decision to standardise on the NT based on availability of parts and feasible home servicing after looking at them ( and a useful phone conversation with Phil Sheard.) The only big scary is the rear sprocket slipping and that's nasty. I check the tightness of that every so often.

The slot loaders may be better but... they're slot loaders and therefore are not real projectors!

I had an SL-1 for about two weeks. Didn't like it. Sold it. I like manual threading and nothing else will do it.

Steven, I agree; "rear sprocket slipping" VERY SCARY! [Eek!]

Rear sprocket slipping??

Can you describe what happens here? I've never seen this.

Well, the sprocket wheel/disc seems to be held from moving only by the large Phillips screw in the centre. If this screw, easily accessible of course, isn't tight the 'nasty' is that either the film piles up in the lower loop OR the take up pulls the lower loop flat and the claw then can damage perforations. Much worse. If you have the service manual you can see that under the black cap there is a little locking collar thingy but these can decay. Every so often I check both centre screws are tight - easily done, actually.

Thanks.
I'll be checking before each use from now on.
