Clamps: https://i.imgur.com/VkjFngU.jpg (I did have 3 but cut one down to try and bolt it therough spoil board - so I'm currently looking to replace them all tbh - they are well used)

Thing with using my router to make the spoil board with counter sunk holes and what not is how would I be able to line up the tee slots, and I need the whole sheet for the signs in cutting out really. With clamps I still get a lot of waste as I have to set my work piece origin after them.

Really I just need more clamps - or at least decent Tee bolts for my clamps to sit in.
