Thanks guys. They will be taken to and from various sites so will need something robust. I wont be buying the festool bag as it only has padding one side now.
Plus the job i am on at the moment requires cutting sheets length and width wise. So i will need 3 1400mm rails.
So i will make the case big enough for 3 rails.
As to the kit at the moment i am undecided between the 2 rail kit and the 2 rail/ angle guide accessory kit.
Due to working through agencies and the way the expenses work, i can only claim for a max of £500 in one item. So the 2 rail/ accessory kit puts me over that limit.
I might even pop to axi after work to pick up a rail in readiness.
