I'm trying to get an old Bell and Howell TQ1 655 working again (after many decades of sitting in a shed). I've cleaned it (a lot) and changed the socket from a bizarre 5-pin thing to a 3-pin. I then powered it up for the first time yesterday. It came to life straight off, remarkably. One of the drive belts has slipped, which I need to remedy at some point, but the motor seems fine.

The biggest issue that I can spot so far is that projection bulb is clearly past it. It's gone all crusty and won't glow at all, despite the filament being intact inside the glass. It obviously needs replacing. What's the best replacement to go for? I see there are a few options online. In an ideal world, it would be nice to get something that has an in-built reflector dish, as the existing one is cracked and will probably smash at some point, if I don't get there first.

Another thing I'm going to have to check is the worm-gear. I've seen a few videos online regarding this and it's obviously a common area to find a fault. Mind you, I'm putting this off for the time being as (rather embarrassingly) I don't seem to be able to locate where the blasted thing sits in the housing. And until I can find it, I can't very well check it. I suspect that it might be lurking behind an additional gear assembly that I believe to have something to do with the animation function.

Anyway, any advice (especially on the bulb and gear) would be very welcome. Never done any work on a 16mm machine before, having only ever used super 8 and standard 8 in the past. So, feeling my way a tad here.

A little over an inch accross and yours will look aluminiumy in the centre and covered with white nylon formimg the worm thread.

It might already show cracks in the whitish nylon.

David Guest is your man if you want it sorting reasonably.

Best Mark.

Thank you very much. I'll open it up again tomorrow and have another look. When I look in, will I likely see it straightaway, or do I need to remove any components in order to expose it?

Kevin Brown's website shows the parts of a Bell & Howell including the original worm and the black one-piece replacement.

The lamp is an A1/215. A conversion to use an ELC lamp was once available for this model.

I love those B & H 16mm machines but they do look awful to work on. Am i right on this?

I've not had a chance to do much yet. Things have gotten a bit busy. However, so far, it's not been quite as complex as I'd feared it would be. They seem quite nicely engineered really.
