My 170S Build

7 February 2023

Time spent:  6h
Cumulative time: 9h
Main activities.  Going through the boxes and installing temporary protection to sides of car. Installed horns

The day started with more rummaging through the various boxes and trying to consolidate things into fewer boxes.

Next up was a coat of varnish to the timber section of the boot floor. I am not sure if it is an issue but seemed sense to give it an extra level of protection from rot given that it probably will get wet from time to time and with the carpet there, it could stay damp for quite a time.

In common with most builders, I saw the need to add temporary protection to the sides of the car before I went any further.  I have been saving packaging from Christmas so had plenty of boxes left for cutting up. 

Having done this for one side, I thought about the next stage which was installing the IVA trim around the openings for the suspension.  Clearly this was actually going to be easier without the protection in place so I then did the IVA trim on the unprotected side before I covered it over.  I found the bonnet hook could be useful to help hold the packing whilst I taped it up. 

I was a bit confused about the extent of the IVA trim – my understanding from the delivery guy was that it doesn’t need to go fully around the opening so I did the top half for the non-circular openings and the full circumference of the circular opening. The installation was a bit fiddly but not that difficult, requiring cutting some wedges out of the back of the trim so that it could go bend easily.

The other job was to apply some anti corrosion treatment (ACF-50) in the joint between the aluminium skin and the bottom of the steel framework.  Opinions seem divided as to whether this is actually necessary but I decided to go for it as I can imagine this is a place where grot is bound to gather. I just sprayed some ACF-50 on the unpainted side of the aluminium and let it run down into the joint between the aluminium and the steel. Some of it eventually dribbled out and did stain the unsealed garage floor.

Finally, I have installed the first of the parts on the car – the horns.  They come very tightly bolted to a flat bar.  The actual position of the wiring connections means that the horns need to be rotated on this bar such that the connections end up with next to each other, so I had to slacken off these nuts. Once the other end of the bar is fixed to the car, it was an easy job to fix down using the nyloc nuts provided (the studs onto which these go are already on the car). 

Finally, I wired them up using the purple/yellow striped wires (these are bundled up along with a bag of bits tied to the upper chassis member) and then cable-tied the cable to one of the chassis angled members.
