When figuring out the temperature and timing, I find it helps to hold the iron in one place and count out five seconds, then remove the iron and roll (or press) the spot as it cools. Then check underneath for melt-through before ripping the weld apart to see if it’s bonded fully. If five seconds isn’t right, try six (or four, etc.). If no amount…[Read more]

Thanks Matt, I figured it was fine but wanted to double check.

The iron is up to max, so I think I’m moving a bit slow, I suspect I may need more practice to find how quickly to move.

Hi Blair, it sounds fine to me. If it is 1000D then you should be able to get a good weld without permanently altering the appearance of the fabric – just move a bit faster. It takes some practice to get the timing right. Cheers

I figure instead of starting a new thread I would tag onto this one.

I’ve been doing some testing and I can heat seal the tube fabric to the flooring (1000D I think), but the heat seems to be coming through a little to the underside of the flooring. If it put more tube fabric underneath the floor it kind of sticks, but in a way that there was…[Read more]

Hi, I bought a v3 kit  2 and a half years ago and have finally found time to work on it.

I see them now – it looks like your iron might be a bit too hot, but it’s hard to tell in the pictures. I don’t normally see the woven fabric get shiny like that. (What I see doesn’t look like a problem though.) The fabric shouldn’t melt at all, just the TPU. Lowering the temperature a bit will also reduce the chance of it melting through to the…[Read more]

Thanks. I’ve tried adding pics again although they don’t show much. I’ll get on with the build and keep my fingers crossed!

Hi – your pictures didn’t seem to work (I just see an “image not found” icon), but from what you’ve written it sounds like it’s probably fine. I designed the seams to be way more than wide enough, so even if they’re not perfectly sealed they will be strong enough, within reason. Cheers!

Haha, no worries!

Ah. I just found the link to installing the zipper on the UL, which covers both the position and orientation. I’ll get my coat.
