Tivoli Phil Posted November 12, 2012 Share Posted November 12, 2012 I'm sure someone with more experience that me will be able to help with this, I'm doing a clean out of some old PR Pilot 150 units this week, and upon opening the first one I noticed one of the dichoric filters was rattling around in the bottom of the head. My question is what type of glue or silicone or whatever should I be using to re-attach it to the wheel? It's just not something I've ever had to worry about before. Cheers,Phil Link to comment Share on other sites More sharing options...
Mr Steve Posted November 12, 2012 Share Posted November 12, 2012 At risk of making a pointless post, I used some high temp silicone adhesive when repairing some 812s a few years back. I can't remember the brand but was good for 300 deg and came in a toothpaste style tube. Link to comment Share on other sites More sharing options...
Tivoli Phil Posted November 12, 2012 Author Share Posted November 12, 2012 Sounds like the stuff I need, just wanted to make sure there wasn't some standard thing I'm not aware of. Sounds like a trip out is called for tomorrow. Link to comment Share on other sites More sharing options...
timsabre Posted November 12, 2012 Share Posted November 12, 2012 I have used standard bathroom silicone sealant from B&Q for this. Make sure it really is silicone and not acrylic though.Also when applying the silicone, use a small screwdriver to put a tiny blob on each corner, it's very easy to get too much on and make a horrible smeary mess of the dichroic.

Richard CSL Posted November 13, 2012 Share Posted November 13, 2012 I use standard bathroom translucent silicone all the time, works just fine, even for heat lenses. B&Q about 2.99. Link to comment Share on other sites More sharing options...
Tivoli Phil Posted November 13, 2012 Author Share Posted November 13, 2012 I went with a maplin special good for 220 degrees, I'm sure it will manage. Thanks for all the advice guys, I'll try standard bathroom sealant next time though I promise :P Link to comment Share on other sites More sharing options...
Tivoli Phil Posted November 13, 2012 Author Share Posted November 13, 2012 Hi guys, sorry to go off on a tangent but new issue; One of the units has a colourwheel issue. The stepper motor will not return after its travel. Suggestions? I'm thinking lubricate the wheel first (as it does feel a little stiff) and then if that fails swap the motor for one from a different unit and check for the same problem. If the turns out to be the issue, anyone know a good place to get these motors? Thanks in advance, Phil Link to comment Share on other sites More sharing options...
AfroAlex Posted November 14, 2012 Share Posted November 14, 2012 Give Miltec a call, they are the UK distributors for PR Lighting. :-) Link to comment Share on other sites More sharing options...
Richard CSL Posted November 14, 2012 Share Posted November 14, 2012 or try opening the stepper, a good clean, and flush the bearings with isopropyl alcahol will work (lube with WD40), if not a dremel drum sander , clean the windings laminates, then a good clean, reassemble. Works for me mostly. get at least another year or 2 out of the same stepper. Link to comment Share on other sites More sharing options...
Don Allen Posted November 15, 2012 Share Posted November 15, 2012 I use Loctite 596 Gasket Maker Sensor - Safe / Hi - Temp Silicone. It is high temp up to 316 degrees C and is recommended in the Martin handbooks. It is red goo. Link to comment Share on other sites More sharing options...
Tivoli Phil Posted November 15, 2012 Author Share Posted November 15, 2012 Thanks guys, but as it turns out I was just being very very foolish, one of the screws on the motor shaft was very slightly loose. Tightening that seems to have solved it, for now at least. Link to comment Share on other sites More sharing options...
