The last two days were just sorting out the two fasteners and a bit of glass on the top seat back edges.

It took me a little while to get my head around the Camloc fasteners. I bought these years ago when I was going to update my present Long-EZ cowls, before I even started building. I had to grind a little off the back of this one to get it fitting in the slopping seat back. I made a light aluminium plate, the plate got some alodyne, I added the rivets and used fast set epoxy to get it in place.

Next up I prepped that small cutout area for flox corners and did a two ply layup on the top. That took the afternoon.

Today I got the camloc working and all lined up.

I thought I’d just need two and put the second one in the armrest.

All done with the fast set West epoxy. That is strong enough for this sort of job. I allowed a little epoxy into the sliding area of the nut plate so that was an extra hour with dental bits getting it mobile again. The build can be unforgiving at times.

Here’s my trimmed oxygen holder, with fasteners. You really can make odd shaped things quite easily with fiberglass.

Here’s the unit fitted and locked. I need air circulating at the front and rear so while I’m tempted to use that triangular space at the front of the unit for the voltage converter,  I’d better not. There is slight movement when the whole unit is in place that I will have to address. The vibration of the plane in flight would over time fatigue something. I’m thinking about a removable holder that ensures the unit stays plugged in. This could double as my final fastener.

Meanwhile there are two more issues. I need to see how much rear stick movement might be restricted by the unit. I may have to placard for no rear stick when I have the O2 unit on board. The other thing is deciding if that brick in the picture above is staying or will it be removable? If it stays, I can hard-wire the ‘adapter’ end and have one less failure point where it would need to plug in. I could also permanently mount that brick. The downside is one pound of weight that stays in the plane even when the O2 is out.

Let me know now if you have any ideas! It is tomorrows job.
