Inflatable boat question

Hey guys,

I just got quite some amount PVC tarpaulin and decidet to try to make an
inflatable boat, unfortunately i dont have expiriance with working with this but there is enough time to learn I am looking for information everywhere and it seems that tarpaulin is not exactly the best for this use but i have it and my main goal from this project is to learn something about inflatable making tachniqes and stuff...

Firstly i would like to know what kind of machine should i use for twelding the joints toghether.
If anyone knows something cheep that can do the job it will be great.

Thanks in advance and more questions are coming up for sure

 

They use a special adhesive that "welds" the material together, not machinery.

 

The tubes for RIB boats made ​​of pvc and hypalon the solders are made with glue, depending on what you want to stick. Here's a sample http://www.youtube.com/watch?v=eBNf78Fo1I8
