Reply to "Maui garage find Intermeccanica rebuild"

Just a little more front end progress before 2019. I used the battery box for the A/C evaporator so the battery needed a new home. I'm using an Odyssey PC925 battery (around 26 lbs) and wanted to put it as far forward as possible. Here's how I approached it on the IM.



Why not in the nose as far in front as possible? Just have to figure out a strong way to support it. I'm thinking it needs a lip to rest on.


A little tray made out of aluminum flashing taped to the nose and wiped with oil so it will release seemed like it should work as a mold for the fiberglass.


It's amazing how much resin and cloth went into that little mold. Halfway through, I stuck a bolt and fender washer into the mold and filled it up around it. Boy, talk about an exothermic reaction - this thing was hot for 2 hours. Be sure to use a level so the lip matches the tilt of the bottom of the battery box, otherwise the board won't lie flat.


Test fitting the board on the lip and looking at various battery orientations


Figure out the battery orientation that fits your nose the best way. Don't forget that you'll need to be able to replace the battery at some point. Since I was making some relief cuts in the front of the battery box to let fresh air get into the evaporator, I had room to sit it vertically. It's still tight in the nose. I drilled a large hole in the board on the far side of the battery where it sits on the lip bolt. Four holes in the bottom of the battery box match up with the support board to give vertical and horizontal support. The strap across the top is just a Simpson Strong Tie strap slightly trimmed and rounded at the ends. The board got three layers of fiberglass cloth on the bottom and two layers on the top.

finalSecure and easily replaceable (without having to disconnect the A/C!) The structural bolt is a little bit overkill, but it  make everything secure, easy to disassemble and it fits the Strong Tie strap :-) Just a note, on my car the battery only fits in from the passenger side and I have to hang the tie-down strap on it while putting it into the slot on the board. Tight fit, but it works...hosesEverything locked down. The evaporator ventilation hoses fit well and should find their way into the dash and floorboard without too much fuss and muss. 

Whew. Again hope everyone has a prosperous, love filled, interesting and fun New Year. May you only get warning tickets...
