Found this one, the foil was to figure out the max height of the foam. Of course in the end all the notches where filled with crossbars. But is lighter than a full plate. Topped it with a 3mm plastic sheet so you don't feel the crossbars trough the foam.
I made it more like a slatted base, to save some weight. Will see if a took some pictures while building it. The handle will fowl indeed, i just took it off. Placed the bolts back, so it will not leak inside. Not sure what the original solution is for the handle.
Why would you wanna have a thinner oil in the more tuned engine?
The racing oil i used to use in a different brand motor was 10W60. Then if it would heat further up, there is still thickness in the oil, so pressure is still remained.
I have the indel cruise 49 fitted in my cabinet. But then also the water tank needs to go. Put a standard fridge slider kit on it, so they open together. And hold it in place with a magnet while closed. It works great, doesnt use a lot of power and even has a small freezer compartment.
