The 2nd box is being made as well now. Waiting again untill the glue is hardened.

Will continue with this again tomorrow and also start with the 3rd box. The 4th one will be a bit tricky, there's an extra corner in there. But I don't think I can start with that untill next week.

The first box is all glued up now. It's very sturdy but I think I'll still weld the outsides just to be sure. Will also look better I think once it's sprayed, won't see the edges anymore then.
Also found a way to be able to get the batteries out once they're in, just put a cotton ribbon around one of the batteries. Can then pull this one out and just remove the other ones after that.

This weekend I'll saw the plates for the other 3 boxes as well and glue them together. Then I can start with the smaller pieces.

Today I received the hole drill bits so I could continue again. First I drilled the holes for the cable glands in the plate. After that I glued it again. Now I just need to wait again untill it's hardened. The batteries do fit quite nicely already.

Think I'll start with the next box after this instead of adding the smaller pieces. These pieces are almost all the same size for all the boxes anyway so I could do that in one go later on.

Today I continued with box #1. The glue is hardened and it's very sturdy. Wonder if I really need to weld the outsides, already seems sturdy enough to keep batteries together. I glued another plate now. Just not the last one yet where I still need to make holes as I don't have a hole drill bit with the right size. I only placed it there for the clamps to have some more grip.

Have to wait now untill I receive the hole drill bits I need.

Today I was finally able to start making the battery boxes. Here are the definitive drawings of how I'll be making them. With 4 battery boxes, should all fit nicely. Just still have to see where to place the sensor plate for the display and the fuse with fuse holder. Will probably be as close as possible to the emergency switch so I can keep the cables short.

I started with the biggest box. It'll be the most difficult so I just want to get it done and over with. Here are the plates, nicely tailor-made with my table saw. Only the back plate (as it'll be in the frame) and cover are slightly bigger so I have some play. This will be evened out later on.

I glued two of the plates now, will have to wait untill this is hardened.

Tomorrow I'll continue with the other 2 plates. I just still need to make holes on one side for the cable glands.
