It's not fully housed in well it won't be in real life.  

Depending on cost etc it most likely be out of two pieces any way but just for ease on sketch up I have drawn it one full length.

It will only be slightly housed either side with an upstand piece left in the middle and the perlin will have a slot.

Any way what you think?  Why should it not be housed?    It will have a support bracket behind the perlin I just ain't drawn it on.

i would think about lowering the heels of the arched tie. that will increase the tie effect and get it away from the pulin intersection. i would lay on the purlin ,in full section, with a butress block.  if you can, carefully select the knee timbers and butresses and arch tie. grain orentation will be critical in those components.

cheers.

The drawing was only more of an idea than what it will truly be like due to the time it takes to draw on sketch up.      A butress block I was always intending to use with a nice shape on it because I like the look of them just didnt draw one on the sketch up like I said to DeanSocial.  

Non of this is set in stone yet it could just end up being a standard oak truss like the picture I linked to below.

Thank you for your advice appreciated.

Brett,
I would not call those standard trusses and if you produced trusses identical to those , your client will be over the moon and you should be well happy with what you have created. The nice thing about doing stuff like this is it will be there for hundreds of years into the future.

lol

I know I know,  Its just that its a common truss I see often and I like to be different but also I don't feel its a very challenging truss to build but I can see its the one ill be going for mainly because of time and the client does want to keep the cost down.    She said you recon it will take 2 weeks to build...........?!  ummm I think I could easily do it in two weeks?!

I prefer machining up the oak to get it straight and square but I dont enjoy doing that because the weight of the oak moving it about to much but I have found NO ONE gets it as straight and square to how I like it but getting it done for you will save ALOT of time and back problems and is cheaper lol

I quite like the matching old and new, where stainless steel plates and ties are use, much less material needed for components under tension

So this topic might come to a stand still for a bit sorry!
