Resin fixing

Well that's what I was going to use. I had a few 7.5inch hilti ones from work which I was planning on bedding in the wood slightly so it would then be in the wall a good 4inch, (spacing of 400) but my farther mentioned about using threaded bar with resin as he could get his hands on some,
Thus I'm just wondering which would be better... It makes no difference to me as I can get either for no cost..

If the bricks/mortar are on the soft side, you might be better with resin, as expanding bolts can sometimes crack the bricks. On the other hand, resin is harder to do as you have to work quickly and get the positions right first time.
Why are you using 8x3 on the wall? Why not 8x2?

Only using 8x3 for personal preference really, I know 8x2 is suffice but I don't intend on moving so I'm over engineering a lot to make sure it will last...
I was thinking the same about the resin and getting the bar lined up in time as there are quite a lot of fixing points, I'll try it on one side and see how it goes I think,

There's no real benefit to using a thicker section as a ledger board. The bending and shear stresses on the timber will be tiny. If anything all you will do is nominally increase the tensile stress on the wall fixings. Savev yourself some money and use an 8 by 2.
I'd use resin and not thru bolts or sleeve anchors. As said previously, it's more dependable if the masonry is weak. There are lots of different types of resin, just make sure you get one that is suitable for use in brick, as some aren't. Rawl and Sika are popular and you will find their brochures online. They give shear and tensile forces for their fixings, but you need to know how to work them out. The forces will be small anyway.
Resin is only required to give added security to prevent the bolts being pulled out - ie horizontally.
If there is no, or insignificant pull-out force, as in this application where the load is vertical, then resin fixings are not required
Things stay up perfectly well without resin

As the morta is old and crumbly in some spots I will opt for the resin with M12 bar, i'll use some of the expansive bolts where I can find a good solid stone,
And as for the 8x3 I didn't really think about the shear force E.T.C so I will revert back to the 8x2.. Thanks for all the info/help

Also, the holes need to be really clean for resin, else you can bond onto dust.
