4 September 2018 progress.

This part has been dangerous! Trying to prop the engines in position alone, against the side of the Viper to check for fit. The modules aren't that heavy for a one person lift, but they are EXTREMELY cumbersome. Mainly because they haven't got a hard shell on them yet, so I can't grab and lift from convenient edges.

Now they are in position, I can plan and weld on the attachment struts from frame to frame, using engineering geometries to strengthen it for support.

Today was my one day in a fortnight to spend entirely on the Viper. I got a lot done. The second engine nacelle, (starboard) is now fitted and welded to the frame. It is still modular and breaks in half along it's length then slides off two mounting posts welded into the central fuselage.

Once it got dark I got into rerouting all the power to a panel on the starboard side between the skin of the aircraft and the interior wall. It's a bit messy at the moment, but it all works so now I can tidy it all up.

Update:

Vinyl stickers done, thanks to my friends Ken for printing and Andrew for generating the printable PDF artwork. I got some aluminium plate to put them on and screw them to the interior walls of the cockpit, rather than stick them straight onto painted plywood. They will last a lot longer.

Not sure how durable vinyl is, but have you considered laminating the labels so they last even longer?

Today I ended up buying a $99 digital photo frame. From Andrew creating the file, to David editing it’s settings, James tweaking the format as well, we got this little moving display to play. I had to make a decision about the size, as it is a little bigger than the show’s prop, but I am pretty happy with it overall. I cut the hole bigger and have done without the buttons along the bottom of the screen.

This is awesome. What would your best advice be for someone who is easliy carried away by grand ideas but has trouble sticking to the long haul of actually building something like this? That is if there is any other advice you can give besides the development of hard work and patience, (and love of the subject matter) assuming there is no secret. :D

Thanks. I'll keep that in mind.:) There's a distinction between hard work and commitment. I had to think about that a minute before I realized that.(y)
It's like when you think about the devil doing his utmost to destroy you, everything you love and every plan you have. That's his mission. My mission is to say, you know what shithead? I have much better and stronger people on my side, you are not welcome and you will not succeed in destroying my dreams. Now F off ol' devil.

Whether you commit to a marriage, your offspring, a career or a major project, you have to accept that everything will try to come against it and thwart your plans. Puff up your chest, make fists, strike an attitude and grit your teeth. Face the raging wind head on and push through it.

Fitting the undercarriage.

I really want to make this safe around people. My plan today was to get all three legs attached and supporting the spacecraft, but it took all day to do just one and get it right. The craft modules are light, (except the cockpit), but I am well aware of accumulative weight and the effects of cantilevering over a support.

Over-engineering is the way for me, so lots of steel. I had engineering friends calculate the failure points for me and then I added extra strength to have absolutely no doubt.

I found a 10mm height difference on the horizontal centre line from front to rear over eight metres. I'll fix it in time.

Cockpit canopy frame, MkII.

It's time to replace the temporary plywood frame with a solid aluminium one. Using the ply frame as a guide, I calculated the amount of aluminium I needed and bought it this week. I over-calculated by 170mm, which was pretty fortuitous, considering I just stood in front of the Viper one day and guessed that I would need fourteen metres of flat bar.

Thanks go to my friend Ewan, for helping me roll-form this aluminium bar stock for the cockpit. The piece still has some obvious clean-up and cut to length, but bending it was a lot harder than we both thought it would be. This piece is the very back of the canopy at the top where it seals against the headboard. It's messy, but the basic curve is there so I can now tidy it up with the grinder.

Oh the mathematics...ugh! I hate calculations. I got the radius worked out from the known values of my arc and scribed an accurate radius to tool the edge.

Right now, I am bracketing it all together and grinding in bevels so all the work is done when the TIG welder, (person) welds it all up, hopefully saving me money. If I deliver it to him clean and ready to weld, then all he has to do is fillet all the joins and it's done. I will take it home from there and grind-finish where I need to.

Dog tags for the flight suit arrived as well. I cut them out, drilled, sanded all the edges. Now just ageing them a bit. Another costume prop done. Big shout out to my friend Dar from Gelandangan Marking System for laser etching these for me and another friend Chris for providing the template.
