Looks good! Thanks for posting the picture so people can see how it’s done.

you’re welcome

and thank you 😉

Hi Mikkel, I have just posted an update about this here. I will add the green fabric to the shop so it’s available for pre-order – that’s a good idea. Thanks!

I have used a similar sealing iron (I built my first packraft with one – you can see it in my older videos) and it works fine for sealing, but the ironing surface is too wide for most purposes so it is a bit slow because you have to use the tip or the edge of the iron instead of the flat surface.

The heating tools that I have used do not have…[Read more]

I have my hot plate set at about 244C or 470F.  I have no way to test the exact temp other than the adjusting knob’s markings.  I have my home made irons on the hot plate preheated.  It takes approximately three seconds to weld with a single application of the preheated iron on the fabrics to be welded.  At this temperature the fabric will not bu…[Read more]

Hi Matt.

Any thoughts on when in april the “green stuff” will be available? Could you make it available for preorder?

I’m also looking at this. I live in Europe, so I’ll need a 22ov appliance.
I can se a lot of people using hotair guns, but then you’ll need an extra hand to apply pressure.
There is also a lot of heat sealing irons around that seems interesting, but few of them seem to get hot enough.

This raises a question. I guess the the fabric has specified…[Read more]

This is something similar to what I use,

Be sure to check to see what the temperature range is before you buy one

You will need a hot plate that can hold a steady temperature.  They have some used commercial ones on the big auction site that should do the job for under $100.  The one I have is about $400 but it is more than necessary in my opinion.

I preheat the hot plate to 240 with my irons on it.  I like to have two of each size on the hot plate.  I use…[Read more]

Sounds good! I think if you lay out the patterns efficiently then you might even be able to get away with just one meter for doubling up the outside of the tubes (depending on how high up the walls you want the lamination to go); I think 2 m should be plenty, and you might have enough left over for other things too.

Hi Mike,

I’m interested in trying this method, too. A cheap hot plate would probably work as a heater, or even a clothes iron held in a cradle – anything that would maintain a consistent temperature.

About how long do the irons stay hot before you need to reheat them, and how many of a given size do you need to make so you can switch between…[Read more]

I’d like to add another option for your heat sealing.  I use a commercial hot plate and some “irons” in various sizes to make my welds.  The hot plate is pretty simple and can maintain a steady heat of about 240 degrees.  The irons are home made with aluminum square stock cut to different lengths from 3/4″ to 3″ affixed to cedar blocks with JB we…[Read more]

Interesting – thanks for the post!

I picked up a military surplus Valad Heat Sealing Iron off eBay like one of these: http://www.ebay.com/itm/VALAD-SEALING-IRON-HS3T-150W-120V-HEATING-PARTS-TOOL-HOT-ELECTRIC-MILITARY-USED-/172624490089?hash=item283138ae69:g:Sb0AAOSwoydWqAl8

I didn’t have much luck with the clover either, this is much heavier and seems to hold the heat better.…[Read more]

I see it as a valuable addition to the toolbox that will be used on other jobs too. I have the 1500W version but there is a 1080W version on ebay for the price of a Clover iron, though you need to get the 20mm nozzle separately. Anyone who’s done any gas welding will find this a natural tool to use, though you need to develop some specific skills…[Read more]
