scottishjohn 561 Posted June 2 is there any cost advantage in building your own I say cos I went to an auction and part of the room contents were loads of packs of the metal work for making joists - 300mm +450mm any interest to any one/ Share this post Link to post Share on other sites
PeterW 3,294 Posted June 2 The webs..? They need decent presses and very good jigs to make them work correctly - if they are Wolf Systems ones, the machines are well into 6 figures Share this post Link to post Share on other sites
ProDave 3,579 Posted June 2 The issue would be certification. What timber are you using? is it the right spec? who is going to declare the loading? I would have no problem doing that for a shed or other building that did not need BC approval, but for the main joists of a house? I think not. Share this post Link to post Share on other sites
scottishjohn 561 Posted June 2 just a thought as they are there as you say maybe good for making shed components probably could not the right wood at a good price anyway if not buying in truck loads Share this post Link to post Share on other sites

During my build I have had to learn life is not long enough to do everything. On my build I have done what I am good at / enjoy and contract out what I am not so good at / don’t enjoy. 1 Share this post Link to post Share on other sites
JFDIY 117 Posted June 2 I watched a YouTube clip on making them, not complicated, but you need fairly large flat press plates, the ones on the clip I saw could do a 6m joist in one set-up. But I'm sure if you could press one full web section (2ft?) At a time it could be done Share this post Link to post Share on other sites
ToughButterCup 1,835 Posted June 2 I went to the factory to see ours being made. Talking to the lads, the key thing they pointed to was the quality of the timber : before use, they dropped each piece into a former - a sort of guage - and if it didn't fit, then it was rejected. Without the jig for both the timber and the assembly, I would hesitate even if I were as Just-Bloody-Do-It as you are John. 2 Share this post Link to post Share on other sites
joe90 1,309 Posted June 2 I even considered making my own i joists as I am fairly good with woodwork 🙄 Share this post Link to post Share on other sites
