Furnace?? More like a craftingtable...

Hi everyone, i'm Darkwither and today i've got a small problem.

You see, i wanted to make a mayonnaise maker, that basically worked like a furnace, i followed this tutorial https://www.youtube.com/watch?v=0vnkebRDZfY. as you can see at the end of the vid, there is no progression bar! and in my case there is no time between putting the ingredients and getting the product, and in my case i also wanted the brewing stand feature that uses blaze roads to power itself, so you know it does not really work properly or how i wanted to.

By the way, extra information i also want to be able to display on the texture if there are the eggs in and if the final product is in the machine too.

So in short i need to display whats inside the mayonnaise maker on the texture and have progression bars.
