Morgan sierra 100

I see you have bolted the longerons together at the tail and there does not seem to be much rake for the fin post. Is this temporary? Getting the fin post absolutely vertical is critical. I used a plumb bob & 1 metre level across the fuselage at the steel subframe & blocked the fin post with some full 20 litre drums so there would be no movement when rivetting the post to the rear frame. It was easier to do this before the firewall was installed as I didn't have a bench short enough to have the firewall top & fin post hanging over each end.

Hi Kevin

have set at 5degrees as per drawings but will fix plumb and exact 5 degrees know that it is turned over ,we will be temp fixing airframe to table for stability of any fixing off that we do ,+ we will be using laser levelling and plumb ,thanks for the input

Mine is set at 7 deg which is why it didn't look like much rake in the photo I guess. Most of the later Sierras are at 7 deg. Doesn't make any difference just aesthetics with more slope on the vertical stabiliser/rudder.

Garry changed it for a more streamlined look but the original plans still say 5 deg. You may want to check with Garry as you have a wider cockpit than standard but I think it looks better with a 7 deg rake.

I agree.

Front skin over new alum tank and fire wall between tank and cockpit

 

Hi Gareth

Have you guys built your own alum fuel tank to replace the normal fiberglass one? Have you got any more photos of it

Cheers

Jamie

Hi Jamie

yes we built a 95 litre full alum tank temp installed untill we get the fuel sender and flow valves then we will install and final skin off ,the tank will be coming out tomorrow so that we can seal off the area that tanks it sits in as a fire guard ,we will be making a mock up dash tomorrow (our cockpit is 180mm wider than normal so the dash supplied is to small) then we will make a plug for the fibre glassing also set the brakes and rudder pedals in place ,we are also getting the rudder control cables made up to fit ,we have the elavator glass spars ready for fitting and alignment will take a few more pics tomorrow

cheers gareth

Your fuel tank seems an interesting design. Looks like it slopes down to the floor so if that is the case the fuel gauge will be a fair bit out of whack. Is there any sort of sump/collector and internal baffles? How do you intend to seal the riveted joints?

Hi Kevin

the fuel tank is the same shape as the fibre glass one, what you see is aluminium bulkhead around tank area, cut folded and riveted in pos then sealed up in ternally ,this (in theory) should if tank is punctured in the event of damage ,will not allow fuel into cockpit,(fire in cockpit alarms me) fuel sender will be into sump as per normal

Umm. Dumb question, but assuming you're not aiming to fly it off, how are you going to get it off that platform when the time comes? I think I'm almost as jealous of your work space as I am of your project; almost, but not quite! :thumb up:

LOL ha ha yellow safety rails slide out, long tynes on fork lift, table as well as airplane will be lifted down .work space is utilising space above our heads we pay for it so built the mezz to work on , it will come in handy for storage later on

Great progress Gareth. I have the fuselage of mine around the side of the house while I build the wing spars. I presume the white tubing over the fuel tank carries the electrical cable or is it fuel line. I am not riveting the front deck on till after the engine goes in.
