Reverse Gearbox

Been very busy with university work recently so not had a post for a while, this is one of the reasons! This is the reverse gearbox i had to design and draw for my coursework. It's been a very long day... sorry about the photo quality. The drawing on the left is a view from the left and on the right is a front section, you should be able to spot how things line up. As per usual click the image for a more detailed view.
