Continued work on the cooling system. I applied RTV to create the cooler box door gasket. I also placed RTV in a few other areas around the engine where parts might rub.
Time: 0.5 hrs.

Cooling System 1
I was able to get a good start on the cooling system. I started by cutting lengths of radiator hose and placing springs in them as per plans. I then worked on the cooler box assembly by cutting the stainless steel hinge and attaching the cooler box assembly to firewall.
I need to purchase some more high temp RTV sealant to create the seal so I skipped a few steps for now and installed the oil tank assembly. The oil vent was installed. It required placing a cushion clamp at the location of the gascolator. This was very tricky as there wasn't much room to work in, but I finally got it accomplished.
The overflow bottle was installed along with the overflow tubing which then attached to stem on the expansion tank assembly.
Time: 3

Exhaust System
Started and finished exhaust system today. First place and loosely tightened nuts for exhaust pipes. The springs were then used to attach the muffler. The lower cowl was placed to check for clearance of opening. The muffler was positioned so that there was adequate clearance between muffler pipe and cowl. The nuts were then torqued as per plans. The EGT probes were placed with hose clamps and the wire ran as per plans. I then spent a few moments going through and placing zip ties to wires in the engine area to get them cleaned up.
Time: 1.75 hrs

Cowl Complete
Completed section 38 today. Started by riveting all the hinges to the cowlings. The cowling were then put in place and edges sanded to fit. Plans call for 1/32 inch gap.The 6 holes in front of the cowling were enlarged and nutplates riveted to the lower cowl. The oil door opening was cut in the upper cowling and the oil door fabricated and riveted into place.There was a slight interference with the door opening so it required a little removal of the upper edge of the door. The lower close out was then made per plans and nutplates attached. It is nice to have this section done. Now I can get back to doing engine work.
Time: 4.5 hrs

Cowling trim / hinges
It is a little harder getting out to the shop as it is cold outside. Luckily I have a heater in the shop so I can warm it up some, but it does take some time. I try to find work sessions that will last more than a few minutes to warrant warming up the shop.
I worked on the hinge halves that will go to the cowling. They were cut and marks were placed for future drilling. The eyelets on the curves were beveled. I installed the hinge halves with hinge pins and fluted around the curve.
I think worked on trimming the cowling to the scribe line. The upper one was trimmed with dremel and then hand sanded to the line. The lower was trimmed with the dremel but will have to wait until next time to get it sanded to the scribe line. Not my favorite part of the project but doable.
Time: 2.5 hrs.
