Robert Buncher Posted November 27, 2018 Report Share Posted November 27, 2018 The end cap on my venerable 416 has pulled off a couple times when removing a softie. What would be the best thing to use to glue it back on without it being a permanent bond or messing with the sound. Thanks, Bob Quote Link to comment Share on other sites More sharing options...
The Immoral Mr Teas Posted November 27, 2018 Report Share Posted November 27, 2018 Since it's off just take a look inside down the barrel to see what would be obscured: my guess is sellotape around the edge would do it, trying not to cover the front. I don't have a 416 nor have pulled one apart but have pulled apart it's ancient predecessor, the 805: to find the interference tube inside is in fact a tube with holes along its length (bearing little relationship to the grooves on the fancy exterior) - the important part however is not to cover the (slightly expanding) holes at the mouth of the tube. So a ring of ordinary sellotape/scotch around the side edge might well be fine making sure to not obscure the barrel front. I think the front cap of the 416 has 3 or 4mm edge to play with?

afewmoreyears Posted November 27, 2018 Report Share Posted November 27, 2018 Thats a good question followed by good advice... I thought about it and had no good answer... Tape around the outside would work well and not "glue" the pieces together.. as suggested.. and being clear tape, you would most likely not notice the hack..

Robert Buncher Posted November 27, 2018 Author Report Share Posted November 27, 2018 Thanks for the suggestion. I ran some clear packing tape from the side of the cap down along the sections of the tube with no slots, so not covering any openings. I’ll see how that holds.

Glen Deakin Posted November 27, 2018 Report Share Posted November 27, 2018 Iif that doesn't work and you don't want to tape it up what about a replacement shell from Sennheiser. I'm sure they'd sell you a nice new one. Quote Link to comment Share on other sites More sharing options...

Robert Buncher Posted November 28, 2018 Author Report Share Posted November 28, 2018 I originally thought of using a couple small drops of loctite, the non-permanent red version. I’ll give the tape a try. Quote Link to comment Share on other sites More sharing options...
The Immoral Mr Teas Posted November 29, 2018 Report Share Posted November 29, 2018 Bob, I actually just meant a small ring of tape around the barrel at the end. Looking first at the 'real' interference tube inside the barrel making sure not to cover the 'final' hole. This all being based on my experience of the old 805, not a 416: but whatever is inside the latter, do the smallest possible mend making sure to not be obscuring any 'hidden interior' holes/slots/whatever. (Glue of course would obscure nothing inside nor out, but could be somewhat permanent)! J Quote Link to comment Share on other sites More sharing options...
Robert Buncher Posted November 29, 2018 Author Report Share Posted November 29, 2018 Mr Teas, Inside the upper part of the tube, directly underneath a circle of screen, is a type of filling or padding. I could not see beyond that and really didn’t want to be digging into a mic that has been performing well. Are you saying that it is ok to cover over a couple of the first slots?

Hi Robert - 'maybe yes, maybe no!' I'm basing this on my taking apart an 805 which was the '60s long mic which developed into the 815/816 and 415/416: inside the outer tube, inside the 'padding' (basic windshielding), in the 805 the interference tube was (surprisingly to me) a metal tube with little holes drilled along it along the top - and nowhere near as many as the slots suggested in the outer tube. Importantly however the diameter of the holes slightly but gradually increased at the mouth end: so I would assume it's important sound-wise not to cover the last hole(s) with any mend. Perhaps the 416 (or mics later than the 805) didn't have the internal metal tube beneath the padding - but if it is there I would run a little finger or cotton bud inside to locate the 'final hole' (or holes if more than one line - or indeed slots if that's the case). If the innards are such just make sure you don't tape over any part of the final hole. If however there is nothing within the padding that must mean that the (inside) of the outer tube is now the 'real' interference tube design and you possibly can't cover any outside slot. I was surprised at finding the inner interference tube a few years back simply because I'd never been told or read about it in 20+ years of using MKH shotguns! I have no doubt the design will have changed but the difference between the inside and the outside was so significant I have been intrigued (and wanted to pull apart a 416) ever since. If you can't see or feel inside the 416 however (or if the design has radically changed) I would just go with a spot of epoxy and you wouldn't be obscuring anything nor altering the sound. Best, Jez WAIT ! Sorry I understand - I think the 'filling/padding' you're talking about is just a short bung of sponge inside the tube? For 'from the front' basic wind shielding? If so does it look like there is secondary inner tube or is all obscured? We might well have to wait for a (good) Samaritan here with a dead 416 to pull it apart and tell us! I would guess it's just a short bung up front but I wouldn't want to encourage any needless destruction that you're trying to avoid! Go with the smallest amount of tape you can - a few millimetres, obscuring nothing! Quote Link to comment Share on other sites More sharing options...
Robert Buncher Posted November 30, 2018 Author Report Share Posted November 30, 2018 Thanks Mr. Teas. I’ll continue on with the small amount of tape I have applied. If that fails I use a small amount if non-permanent adhesive. Quote Link to comment Share on other sites More sharing options...
