Build the Dream, Live the legend, Fly your Own Fighter!

Good Morning,

I did a little bit of work on my custom tank. I hate proseal...almost as much as I hate fiberglass. This time I used the proseal a little different than before, I do not rivet it wet. I seal it up and clecko it together in every hole and let it dry completely for a couple of days, then later apply a little bit of proseal in every hole and rivet it. Less of a mess.

Here is the Tank sumpy flange glued and riveted in place
Image

Tank filler neck flange glued into place
Image

Tank sight gauge fittings top and bottom respectively
Image
Image

Tank sumpy, bottom fitting is for water drain and 3/4 up is the fuel outlet. It is just Alutube with an Alu plug that fits on the tank sump flange.
Image

The sumpy installed and glued to the bottom of the tank on the bottom flange.
Image

Then I glued the 2 sides in the tank and close the top lid, reached through the inspection/access hole and sealed the insides. I put a clecko in every hole and let it dry for a couple of days. Picture below is of the Top of the tank with filler flange and inspection/access hole
Image

Right side up, front view, with sumpy down.
Image

I specifically planned the side flanges and rear baffle flange so the rivets sit exterior of the tank to aid sealing and easy rivet squeezing, instead of trying to reach inside the tank to try and set those rivets. Sometimes taking it slowly helps with the thinking process.. :mrgreen:

This week is Battlefields Fly-in, so I will let the tank proseal dry some more and next week rivet it complete.

Till next time
Groete

Hey Arie, affirm! The filler neck is going to extend +/- 150mm above the tank and then I will drill a small hole in the fuel cap.

Build the Dream, Live the legend, Fly your Own Fighter!

Good Morning,

More custom tank building...I riveted the sides, and mounting brackets, this was much easier and less messy if the pro seal dries first with the cleckos in every hole. Then I rivited the nutplates for the inspection cover.
Image

I bought some gasket material from Midas, and use the repurposed cleveland wheel cover as the tank inspection cover, and cut and created the gasket.
Image

Installed the inspection cover with some fuel lube, because I want it removable in case of leak detection.
Image

Then I did the balloon leak test, seal all the tank exits and pump the tank full air to inflate the balloon on one exit, basically putting the tank under internal pressure, then I and used soapy water over all the joints to inspect...SUCCESS a leak-free custom tank!
Image

I turned my attention to the Firewall Forward, and started to mount the Oil Tank on the firewall. I want to see if i can complete all the Firewall forward mounting stuff, before the tank goes back into the fuselage, since the tank is in the way of drilling and mounting stuff on the firewall...more pictures on that next week.

This custom building stuff takes a lot of time and planning...then you have to find and purchase and wait for delivery of the right stuff. Comparatively the Vans RV kits make it very simple, everything is thought out for you and everything is supplied...you just do and no waiting time cause everything is in the box! That said I am enjoying this build and there is a different kind of satisfaction doing scratch build/custom build stuff.

Till Next Time,
Regards
Rudi

This custom building is also seriously affecting all of us following your build... the updates don't come nearly quick enough!

Well done! Can't wait to see the next installment.

Build the Dream, Live the legend, Fly your Own Fighter!

Good Afternoon,

I think when Professional Builders / AMO's look at us home builders the laugh at us. We can fiddle with a bracket for hours and get satisfaction out of it :mrgreen: ... this week was one of those.

I finally fitted the external oil tank for the HKS, it is a dry sump engine just like the Rotax 912's. Everything is custom and I worked out the oil pipe routing and it necessitated the tank being moved off the firewall for one oil pipe to route behind it, and P-clamped to the Firewall on the hidden side behind this tank photo. I could not P clamp it on the engine mount because that pipe run will be too short 100mm to the engine and the engine movement on 100mm straight run will put strain on the pipe if I clamped it there...so I created a non-chaffing point on the engine mount if it touches due to engine movement and clamped it on the firewall instead, behind the oil tank. PS: Engine mounting nuts are temporary before someone erks... [-X
Image

Then I repurposed some Angle Iron that came with the crating of my RV10 Lycoming Engine, to aid as Oil Cooler brackets. Marking out the 1st bracket. This is where all the bracket fiddling came about, creating a custom bracket with hand tools only.
Image

Handtools and hacksaw it
Image

Clean and fit and fiddle...Ah, satisfaction it fits!
Image

Repeat and make the mirror image
Image

More hand tools and home builder fiddle fiddle...satisfaction done!
Image

Trail fit the oil cooler and custom brackets on the engine...perfect! (Tempory bolts) Front View
Image

Side View (Note I still need to put a custom exhaust into that space behind the oil cooler and forward the firewall.
Image

Dissamble and paint steel brackets, put it aside to try for assembly later this week.

Then I packed out the Ignition coils, CDI units and Regulator, to start to figure out where on the firewall I wanted to install these.
Image

This week I want to complete the oil cooler installation and route all the oil lines, then I also want to mount the above to the firewall and route their wires and spark plug wires. All custom work, cause there are no firewall forward plans.

Till Next Time.
Groete

Hi Rudi
This is a quality build =D>
You might have too much cooling with that cooler, but suppose one can always close it a bit later.
Cheers

Hi Johan, thank you! This engine came out of a savanah/oribi and in that installation, it had 2 of these coolers, that came with when I bought the engine. I am re-using only one, but it will be easy to close off a bit with velcro to tune it for summer and winter flying.
