  2. Where we are now: The site is back up and running! The character set encoding issue has been fixed so old posts should now look ok. I am currently working on themes/skins etc and I will be deleting the temporary green skin very soon as it has many issues. I will do a very quick variation on the stock blue skin first just to get a light-grey background and san-serif font, and I will set this as default. Later this week I will hopefully add a professional third-party skin in pfm colours (life is way too short to do this crap myself, and I've found one I really like than needs next to no tweaking). We are getting there slowly...

I ask as I’m getting countless bounce errors as the server fails to send notifications through etc. I’ll eventually figure out how to send these to a black hole somewhere, but it makes sense to address it at source as quite a few folk are obviously not getting the thread and conversations notifications they have set in their preferences.

    I use the side of a hot soldering iron bit (not the tip)

    Same here, I use the lower part of my soldering iron tip. Make sure it's clean first. I sometimes use one of those long lighters with an adjustable flame.

    I use the side of my soldering iron, just held close, no direct contact.

    A hair-dryer won't get near hot enough.
    It depends on the size and what you are sleeving. If you can rotate the item being sleeved, and hold it several inches above a cooker ring, that will produce a better finish more quickly and more easily than using a soldering-iron.

    The soldering iron method is quite good for one or two applications but if you have much heatshrinking to do a heat gun is preferable. Proper ones are quite expensive but I have used a Black & Decker paint stripping gun for many years now, normally on the lower setting.
    I haven`t tried a hairdryer but I suspect it wouldn`t be hot enough, also difficult to direct the heat only to where it is needed.

    I have a hot air station which works brilliantly but if the iron is already heated up and I only have a couple of items to do then I use my iron. I also have an Iroda Pro gas iron (well three of them actually) with blow torch and hot air attachments which are easily the best tool for the job. They have proven invaluable over the years for field work both on PA systems and Auto installs.

    By far the best thing I have ever used for heat shrink is a cheap electric hot air paint stripper. They start from about £12 new, but I paid £4 for mine second hand. i'm sure it would be pretty crap for its designed purpose, but offers fast heat up and very hot air. Works a treat.

    Hot air gun. Or a lighter in an emergency. I have reels of the stuff, up to 2" dia, and an adjustable hot air gun is the only sensible method.

    Heat gun is awesome, but usually I use a gas soldering iron and the exhaust on the side is perfect in most occasions.

    Your Weller gun looks great Pete!

    Just after putting some of this onto the wiring loom of an old motorbike. Got a box of assorted diameter sheaths from the local motor-factors. Looks to be a fairly basic rubber compound - no fancy braiding or suchlike. It ss marked '125 deg C'. A hair-dryer worked perfectly on it.

    Hold it over an open gas flame on your cooker if you have one, works a treat for me, takes a few seconds to shrink.

    A hot air gun does work very well.

    Anyone up for a loan of my 2 belden home made cables.

    Have a 5m extension lead too, fitted with iec.

    will happily post them out to anyone who wishes to give them a go, just pay return postage.

    Maybe the op would be interested, he seemed curious.

    A bit tricky when you have all this to do.

    Would be best avoided :)

    Great for cables though.

    Late to the thread, but another vote for a paint stripper/heat gun.

    Nothing like the satisfaction of watching the heat shrink reducing in size over a good joint. (Solder not the, err, other type)

    Heat gun here too. Great for getting certain types of sticky labels off LP sleeves too!
