My MacBook is a 2015 model and has been having battery issues for a while now. I've been limping along for a couple of years with short battery life, but it finally got so bad that the battery was physically hot and it would shut down randomly even when plugged in. I finally bit the bullet and sent it off for a $500ish battery replacement, only to be told a week later that Apple considers it obsolete and will no longer sell replacement batteries or otherwise service it. Drat. I got that sorted with a replacement a couple of days ago and finally got around too getting everything essential migrated over today. Based on that, as well as a bunch of other extraneous stuff, it's been about 3 weeks since my last entry, or really since much progress on the project. This entry represents probably 10-20 hours over 3 weeks, with a lot of that being scheming and planning stuff that should be easy but just wasn't. Installed the throttle and mixture cable brackets on the engine, and trial fit the cables that I had on hand. I'm not happy with the routing and am going to order a 54" mixture cable to replace the 51" that I had picked up from somebody on VAF. Also, I had the original RV7 oil cooler lines so I used them for a trial fit. Due to the placement of my oil cooler, I'm not able to use standard RV7 or RV14 routing for these lines. Or at least not without causing potential problems on down the line. Specifically, the outboard oil cooler port is just barely located where I can get a b nut from the line onto a straight fitting and I don't have much confidence that it won't rub as stuff vibrates and flops around in there. It would have been a lot easier if I had located this cooler 1" lower and 1" inboard, but here we are. Ultimately, even though it would have been really nice to be able to use standard prefab hoses here, the reality is that the bend radius requirement for the hoses cause an issue for the outboard hose and the fact that I have to pull the P-mags for inspection every 100 hours lead me to not want route the other one behind/below the mags for the other one. After a lot of though and monkeying around with mockups and whatnot, I think I have a solution that makes sense. The hose from the r/h accessory case port comes over the top of the oil filter and mags to the inbd. fitting on the oil cooler, and the l/h one does off the accessory case in a gentle curve between two engine mount tubes to the outboard oil cooler port. The black hose in the picture is a mockup made from a kit I bough on amazon intended for roll your own race car lines. In oder to clear everything by a comfortable margin, as well as have some assurance that it won't be able to unscrew itself as a result of engine torque, there is a steel 45 on the back of the engine to a 45 on the hose, and a similar setup on the cooler end. This will obviously require a custom hose, but I was planning to have TS flightlines build these with firesleeve anyway, so no harm done and I think this will work well. It's 15 degrees outside right now and not a lot warmer in the shop, so I'm spending my shop time today catching up on this entry and getting a list together for stuff I need to order to move forward with these plumbing and engine rigging projects.
