So, issue found.

 

A brass bearing was loose and oil passed by the valves, i was the first to have this issue.

 

Engine should be back next week.

Good to hear. Also what is very promising is that the factory appears to be very happy to sort issues as they arise and are not trying to duck the issue or pass it on elsewhere.

Yes, that gives me a lot of confidence. Clients/Customers want solutions, not excuses. It seems as if D Motor is providing solutions.

Ok, they are upgrading my oil pump from one that needs to be bled to one that can suck oil, a newer version.

 

While they are pulling the engine apart I also asked them to anodise the engine mount since I've got light surface corrosion, I'm the first customer who asks for this, the engine has bare aluminium parts and I have a cold storage hangar that can get very moist and cold in winter.

 

Engine delayed till end of august.

They drove back up to me and helped me assemble the aircraft again, new oil pump was really good, instant oil pressure.

 

They wanted me to change the flow of water so now i have a thermostat directly after engine, the thermo bob is gone and in came a simple one, thus making water flowing through the radiators and not shock cooling the engine when thermostat opened, when rerouting the water i no longer got flow into the cabin heater so im moving the hoses around for that.

 

Also another weird thing is that now after water is cooled, the cylinder coolant inlets are positioned right by the coolant temp meter, so i get 20C less measured at efis compared to the ecu´s water temp meter that is positioned after engine, i told them i dont agree on the position of efis coolant temp meter, i'm now installing a inline water meter after the cylinder outlets so i can read same temp as ECU/thermostat, this worked better when i had the thermo bob.

They should probably be paying you for beta-testing the engine for them. You haven't had a good run with it so far.

Ive been out visiting friends.

 

And a new year has begun.

I poured foam over it and it looked like this.

20190426_180857.thumb.jpg.fd3a042d03bc7cb9ef503da989c3baf0.jpg

And then i sanded it down a bit to get a feeling, and i like it allot more than the old one that was a compromise.

That cowl really alters the looks of the front.

Got the shape ready, was a pain in the arse to sand the 2 part filler and now i have used liquid filler, next is to sand the filling one more time and then spray with 2 part paint and then on to the polyester mold.

Nice work; that is why we call the sanding / shaping board a 'Torture board' :)

Hi Dennis

Looking a nice shape. Hope you don't mind this question. Is your finish surface product suitable for the tooling gel coat or gel coat and layups? Wax alone will not protect certain coatings from reacting in a bad damaging way. Some coatings are damaged during the cure of the gel coat layer and result in a wrinkled mould surface. If your unsure about being a satisfactory product check with a local fibreglass shop experienced in moulding off patterns or atleast trial a sample piece before doing the mould layups on your cowl pattern. I learn't the hard way years ago. Cheers and best wishes

Gelcoat time.

20190522_144859.thumb.jpg.0ce183a400e91d5455f9801ba5530821.jpg

And as Seperator i used tongue depressor and hot glue.

20190521_183311.thumb.jpg.a6b56192193c29ef81ff40dcc4f000af.jpg

And another intresting fact, temperature rose from 5C to 24C in the pas few days, so filler expanded and i had to sand some spots...

Yeah thanks, i did a test sample and it worked out nice, the liquid filler did not like the curing heat so i lowered the mix volume of hardener and i used allot of extra wax.
