Hot air

Post by Mark R » Wed Oct 05, 2011 10:21 pm

I still haven't popped out the stove-in end of my creek boat, after this unfortunate miscalculation...

I tried hot water to no avail. So...please recommend me a hot air gun, and any tips on how to use it most welcome.

Be sure to try the broom handle in addition to hot water inside and a hot air gun from the outside. Good luck

For what it's worth I had a particularly badly pig nosed Habitat to deal with in Chile 2 years back. It also resisted simple hot water in the end treatment and I finally ended up stringing it from the rear grab loop in a tree with the nose hanging into a giant pot of boiling water (with the camping stove beneath) and another massive pot of boiling water poured inside (after preheating it with earlier hot water). Then some serious force with a blunt long object (aka Brush handle, baseball bat etc) from the inside.

Needless to say Health and Safety don't approve this particular setup!

I use the hot water method then hitting it with a fat head mallet, seems to work

Not the first or the last to be scalped there! It looks like such an insignificant amount of water going down the drop, surely not a problem for a creeker!?

Simon, I think you might be pushing your luck trying to get the dent out of your boat...

I'd be tempted to leave it as is, Surman-style!

Hmm, my hot air solution can turn steel or cast iron cherry red and melt brass, silver, aluminium.... need to be very careful waving it around the end of a boat!

I have one of these:

I use it to weld splits in boats, but a friend recently used it to dry foam.

You can get a cheaper version with no LCD and just on/off, but I liked the thought of having some idea of how hot things were getting.

I've got an old one of these which looks like it would help with the job if used with care. There is a picture of one being used by Paul Mason in his book.

(Price doesn't include a gas bottle)

More seriously, Earlex and Black & Decker have common parentage and as far as I can tell the Earlex wallpaper stripper I have is identical to a B&D stripper but about 2/3 the price. By that logic the Earlex hot air gun (which I also have and have not had any problems with) is probably identical to and significantly cheaper than a B&D model.

Probably not super helpful, but if you've got a handy Sauna lying around chuck it in there for a few hours, works wonders. I saw a boat that looked more like a pancake pop out completely after a few hours in a nice toasty sauna in Switzerland.

I seem to remember one of my modified H3s reverting to more like it's former self whist spending 2 weeks in the Alps. I suspect it was whilst on the roofrack in the sun rather than on the alpine rivers. Gentle heat is the way forward.

I think the local leisure centre might get fed up of people walking into their sauna with dented kayaks :)

After lots of comments and askance looks on the river yesterday, I gave this another try.

I'd previously tried the gallons-of-boiling-water-inside-and-out method, with no success.

Today I tried boiling water inside, hot air gun outside ... it had some success, but the dent is mostly still there and I'll give it another try later in the week. The plastic can survive multiple heatings, right???


Precariously hanging a boiling-water-filled kayak from a wonky fence above a 600 degrees C hot air gun and associated electrical leads ... easily the most dangerous thing I've ever done involving a kayak.

Keeping the nose at a safe distance from a real hot fire with embers should get it soft enough. The plastic has a memory from its molding and usually goes back to place.

Of course if all else fails Mark see this thread http://www.ukriversguidebook.co.uk/foru ... =3&t=84299

Hope the hot air/water treatment works well.

I tried to push the dent out of mine the other day. So I poured the hot water in and watched it all come out of a crack in the nose that I hadn't noticed. It explains why I kept getting so much water in the boat whilst paddling it though I guess.
