In response to a request from a customer, I’ve started selling pairs of wooden heat sealing forms in the DIY Packraft shop. These tools aren’t required for making a packraft, but they do make joining the tubes together a bit easier compared to draping the fabric over an overturned bowl (see the Heat Sealing page for details about how this works).
The pair of forms weighs over 600 grams (well over a pound), so adding them to an order may increase the shipping cost, especially if you’re overseas.
Note that the forms pictured above are made from dimensional lumber, but the forms I make now are MDF (medium density fiberboard) and are very close to the same width as the packraft’s seam strips.
If you have any questions, please leave a comment below. Thanks!

Seems like a large round log of firewood might have a similar radius. Could that work instead?

If you cut off a thin slice and sand the edge smooth then yes, but if it’s too long it will not work in corners and if it’s not smooth then you won’t get even pressure under the iron… I think a scrap of lumber would be easier to make serviceable.
