I need to install perlins for a pergoal and they need to be 18' 4". My lumber yard said they would cost a pretty penny for them to get the pt company to make 2 x 2 x 20'. Any other ideas on what to do? Should I just take 8' and just have splices over the rafters?

Any chance of you making them yourself? The couple of pergolas I have worked on we cut all perlins in our shop.

I'm just not that sure that splicing them would hold up in the long term.

What material are you making them out of?

When you talk about making them myself you mean ripping a 20' 2x to 1.5 inches wide?

Just splice them over rafters. It's pressure treated. It will look like crap at the end of the summer anyway.:no:

Ok, first there is no problem getting PT 20' long. Now get a rip guide for your skillsaw (wormdrive ) Rip the 2x lumber to the 1 1/2" and brush on the pt stain.

Done, piece of cake :thumbsup:

8' and 12' pickets (2x2)with breaks. 8 and 12 should be perfect unless your framing layout doesn't quite fit the numbers, then 2 - 12' pickets per run.
