PostPosted: Fri Oct 09, 2009 12:04 pm 
I am about to buy a heat gun for Yost designed PVC coated polyester fabric/HH-66 adhesive kayak construction and am asking for advice on brands/parameters/sources. Of course I would like to find the least expensive tool that will do the job well.

The cheapest heat gun costs about $30 at Home Depot. Only hair blower can be cheaper, I think. I found working with heat gun somewhat tricky - you have to learn how close to hold the gun to the material, and how fast to move it along, and on what setting (mine had 2 settings). Too close or too long time at some spot - and polymer coat will melt.

Like Alex said, a cheapo $30.00 heat gun / paint stripper from any Big Box store will do.
Mine is a "Milwaulkee" with 1300 watts with 2-speeds.

Another option is a monocote gun from an R/C hobby shop, or online. I used one for many years.
Mine was a "Royal" and had 1000 watts and 2 speeds.

A hair dryer is a bit too low powered for this application and doesn't usually concentrate the airflow like a heat gun.

The MonoKote gun from a hobby shop will run you about $15, but will be substantially slower than the $30 gun from Home Despot. Once you own one, you will find uses for it. Nothing better for shrinking shrink tubing onto electrical connections, etc. Just make sure no one tries to use it to blow-dry hair -- it will burn open skin.

Stripping paint off as well - though chemical stuff is often better. My heat gun is collecting dust after I've sold the only PVC hull that I owned. Electrical connections I insulate in a very low-tech manner, with electrician's tape (also has many other uses both at home and in a folder frame, I even carry a small roll in expedition repair kit).

I built my Sea Ranger using an old hair dryer but for my Sonnet I bought a heat gun (Steinel HL 1910 E electronic).

I don't remember the price but I think it was around 60 €.
I strongly recommend that you buy a heat gun with temperature control.

hi thomas

what's the reason why your sonnet has so high contrast airtubes??? a kind of glueing???

in this way it looks very similar to the grabner discovery

I hope I don't missunderstand your question but the color of the sponson sleeves is more bright compared to the color of hull.

Regards from Werder,

Thomas

Das PVC der Schlauchhülsen ist deutlich heller.

*g* I know this scribble and thaught, that the stringer is inside hull between the tubes and not between tubes and skin. It seemed to me that the tubes und skin are melted together where in the scribble the stringer is drawn

Dschin,

Scroll to the bottom at the link below for a description of how the sleeves and aluminum tubes attach. It's PVC hull, glued PVC sleeves, aluminum stringer... in that order.

No... you didn't get me right. Why would one inflate the sponsons before attaching the aluminum stringer ?
The inflated sponsons trap the aluminum tubes, not the other way around as is thoroughly described in the manual.
