Quite some work has been going to to finalise the firewall. Where to put things? What will be in the way? Now the coolant pumps have been positioned I can get this done.

This is the expansion tank about to get its clickbonds foxed to the firewall.

I’ve had this tank extensively modified, but it still needs changes. The welder did a great job and what I asked for. I just didn’t really have the right information. The sight gauge needs to go to the side due to the engine mount being too close. The radiator cap is too high and it hits the top cowl so that has to move. I think I will put the overflow bottle on the left side now, so that fitting needs to move too.

I’ve had quite a time working out the sensors for this plane and where to put them. I think I have most of it sorted. I bought an RV sensor block mount and I have cut it up as it will work better separated and take up less space. You can not just mount these brass sensors to the engine. The vibrations will break them in time so remote mounting via a hose is needed.

You get the idea. I’m using little pockets that would be otherwise wasted space.

Once I had things in place it was time to remove the engine to really get this firewall done. When the engine goes back, it may be the last time before a lot of flying happens.

Sure a little messy now. I like using hot glue instead of clamps sometimes. It is soooo much easier for some jobs.

You get the idea.

After the initial glue is cured I get to remove the items and go to the next stage.

Each clickbond also gets two ply of glass to make it really strong.

Two plies of glass in place now. Once cured, I can move on to the next stage
