Matt, you've had that problem for quite a while, haven't you, it was like it when I last ran those machines, some months ago now, but as far as I remember, it was ok the previous time I was there, a year or so before that. If I remember correctly, it's the right hand machine, and opening is ok, it's just closing that's slow, is this correct?
Did it suddenly happen, or did it gradually get worse? Kinoton changeovers do seem to be rather sluggish generally in my experience, but that one was certainly worse than usual.
Steve Wilsher warned me about it, but I tend to run adverts and trailers on the right, and start the feature on the left anyway, but it still seemed slow to me, when closing after the adverts.
I wouldn't have thought it would be a great deal hotter after an hour than after 15 minutes. Is the 1600 Watt figure correct, I thought you were on 1k lamps, or am I thinking of somewhere else? Either way there's not a great deal of heat there. How is it when the machine is completely cold? It's not a remote box problem, it's just the same from the buttons on the column.
I've run plenty of Kinotons, but I haven't looked inside one for years, and I think the ones I have seen inside were all early 20s, they may have changed the design since then. Are they solenoid opened and spring closed? [ 01-12-2004, 11:49 AM: Message edited by: Stephen Furley ]

Thanks folks,
I can't say i was expecting someone who's actually ran the projector in question to pop up! I don't think we've ever actually met, Stephen - you've probably only ever seen Steve Wilsher. Yes, it is the same problem that we've had for a while although it's become much worse recently. At the end of the film we've been getting a fair bit of leader on the curtains!
I'm told by Steve that they are 1.6ks but we underrun them. It definately a 2k Lamphouse.
Apologies for the lateness in replying - I've been waiting to see whether the fix was permanent or temporary, but it seems to be permanent. I also keep getting stung by your "Bookmarking Not Allowed" function which seems to disagree with my use of the back button. I can't find any settings for HTTP_Referer anywhere, so if anyone has an idea what I'm doing wrong, drop me an e-mail. matt_frankish@croydon.gov.uk. I'm running Mac OSX.2.8 and Safari 1.0.1
Anyway, back on-topic:
We took the gate cover off and had a poke about inside. The stopper is actually made of brass or a similar metal and didn't seem damaged in any way. So, we opened the other one (that works fine) and did a compare and contrast. After a bit of back and forth-ing it seems that the spring that closes the shutter was fitted slightly differently on the two mechanisms. We put a lot more tension on the dodgy one and it seems to have done the trick! There is some bounce, but it isn't visible onscreen.
So thank you all. It seems our problem is dealt with.
