Another Jig is this:

But I guess the jasper is a better choice.
Bubbleboy: Ofcourse 2269 would be nice
But they will cost 3 times more than the BMS and I think the result will be simular. The 2269 cost extra with shipping, tax and duty. The BMS I can get 2 for around 1050euro ink shipping.
Regarding the baffle step I don`t know how to do it with reasonable work and a ok result. Most likley I skip it and do a simular construction as the other DIYers.
My first plan was to paint the boxes in high glossy white but now I thinking of black because I will use them in my HT.
