MANY thanks for the reply, really helpful, I appreciate it.

Those bulges don't need to be rectangle they could be any shape, e.g. I guess round following the shape of the holes? I just need something to give the holes a wall thickness, you know what I mean? I drew them as rectangles because I sort of assumed it's be simpler to machine, probably completely wrong!

I'm also re-doing the drawing to make the pocket corners a radius rather than square which i assumed would also get the drawing thrown back?

Thanks for advice on tolerances too. I don't really know yet what tolerance I need! I know that's the WRONG thing to say but I am going to work it out somehow before submitting drawings/files for quote...

I'm working on re-doing the drawings now will post asap, if you get a chance to look again, that'd be really cool!

Thanks again :o)
