Tamiya P-51D, Sinai, 1956, Finished, 2.1.18

Recommended Posts

Thank you, Wrench.

 

Thank you, Bud. Ahh yes, the engine. I've been thinking about the engine occasionally while working on the firewall. The more I work on the firewall the more I'm realizing how much work the engine, and the firewall, will require to tie each to the other. Deadline? What deadline? I'm afraid I'm defineately going to miss the deadline. Oh well.

 

Thank you, Richard. I have not looked at using a material other than plastic. I don't have as good of luck with brass as I do with plastic. Sanded plastic grips well with CA. Sanded brass doesn't work that well for me. I'm much more comfortable cutting plastic than brass. I never fail to lose the x-acto point with brass, or, when the blade isn't sharp enough it 'chatters' down the brass leaving a poor cut.

 

I shall do my best, Joe.

 

Thank you, Maru. It's only 'flawless' on the sunny side. This build has taken a lot of evolutions to get to the photo stage.

 

A minor update, that believe you me, has taken a lot of back and forth to reach this point.

Need 6 of these for show. But I probably made about a dozen. Different firewalls have different cowl panel mounting conditions, and I did them all! This is the beginning of the the 'chosen one'. Cut .005 sheet into 1mm strips.

 

DSCN6591.jpg

.060 square rod. .040 deep x 100 strip.

 

DSCN6592.jpg

Trimmed with a single edged razer.

 

DSCN6593.jpg

.020 drill bit hole. I probably should have used something smaller, but I'm going with this.

 

DSCN6594.jpg

Glued to a backing. Trimmed excess. Sanded to shape.

 

DSCN6597.jpg

Ugh! The top and bottom firewall taped together. The bottom firewall attaches to the wing section. I didn't bother taking a picture of the other side. I removed the engine mount toward the center of bottom of the top firewall. You can see it's shadow. The rear part of the engine (I guess it is the carburator inlet) has a pin at its bottom that sets into the top of the carburator inlet 'channel', I guess it is, that gives it some stability. So I took off the mount. We'll see how that works out later, I suppose.

 

DSCN6598.jpg

Starting some detail work on the oil tank. Located a mounting condition at the 'feet'. Oil dip stick and oil cap. Located some pins to help set the top mount. Removed a few fasteners when I was working on a different type of cowl panel mounting condition so I needed to replace them. Not perfect. Oh, well. The wavy bottom of the bottom panel has holes drilled into the 'waves' as the cowling bottom panel is fastened into that.

 

Thanks for looking in. Appreciate your comments a HEAP!

 

Sincerely,

Mark

Another wonderful update Mark! The fact that you haven't employed any aftermarket stuff but scratch-built everything is particularly impressive. I myself will be using some aftermarket stuff, I'm much too lazy, LOL!

 

Keep up the fantastic work Mark.

 

Cheers,

Wolf

Mark, awesome work as usual. Every time you scratch-build some set of tiny details or other, I get more and more impressed. Those cowl fastener brackets are amazing! Thanks for the lesson.

Hi Mark,

I've just caught up with this and am absolutely floored by your skills and their results on show here.

It's obvious you've got at least three things I don't; the patience of a saint, eyesight equivalent to a microscope and the fingers of a micro-surgeon.

I'm thoroughly enjoying your work and can't wait for more.

Grant

'Another wonderful update Mark! The fact that you haven't employed any aftermarket stuff but scratch-built everything is particularly impressive. I myself will be using some aftermarket stuff, I'm much too lazy, LOL!'

Thanks a heap, Wolf. For me it seems to be less expensive to buy or find the supplies to make the parts than it is to buy aftermarket. Aftermarket can be expensive on a per plane/tank basis. Supply cost can be divided over multiple builds. I've been known to be wrong. But I have bought stuff I can't make, tho. You're too lazy. That is a laugh.

 

Thank you, Bud. It was a lot of back and forth work to reach that point, but it was so small.

 

'Mark, awesome work as usual. Every time you scratch-build some set of tiny details or other, I get more and more impressed. Those cowl fastener brackets are amazing! Thanks for the lesson.'

 

Thank you very much, Kevin. This build is pushing my envelope. It has taken a lot of work (read: failures) to get to the photography point. Thank you for the compliment on the brackets.

 

You are most welcome for the lesson. I am only too happy to share. I have no secrets. What I do is open source. I had found early-on in my scratch-building efforts that many who did it were secretive, and didn't want to share. I didn't 'get' it then, and I still don't 'get' it now. Learning is fundamental.

 

'Lesson for me today: jigs keep the results consitent - see the fasteners!'

All it takes is taking the time to make one. The simpler the better.

 

'. . . am absolutely floored by your skills and their results . . . '

Thank you, Grant.

 

'It's obvious you've got at least three things I don't; the patience of a saint, eyesight equivalent to a microscope and the fingers of a micro-surgeon.'

I don't know if it's patience or tenacity or a bit of both. As for eyesight, a magnifier helps a lot. Don't tell anybody, but I use tweezers because my fingers are so stubby.

 

I thought I would be able to include an update but SWMBO is a-calling. So, I shall return!

 

Thanks for looking in.

Sincerely,

Mark

Made ya look. Just kidding.

Chores and errands are complete so it's back to the drawing board.

 

DSCN6601.jpg

Added a few bits. I don't know what that pipe with green insulation is but I saw it and liked it. The business to the left is wiring to the switch box below. Lost a couple of cowling fastener bases. Oh well.

 

DSCN6602.jpg

Firewall bottom. This connects to the wing. On the left is an engine oil drain box. To the right the fuel strainer.

 

DSCN6604.jpg

The 'U' shaped item is the oil system tank vent. The right top line is the overflow line to the cowling former. The bottom thin one is the drain. The bottom thick one goes to the engine. Although the image I have has it going back into the firewall. I guess I need to correct that direction. The plug to the bottom right is another drain location. The green wire insulation and the top red wire insulation represent neoprene/rubber connections. The other red insulation is so I can attach the line to the firewall. A couple of hex nuts.

 

DSCN6605.jpg

The top. I forgot to add insulation to the oil vent line connections, and, it looks like a connection to the firewall fell off. Oh well. A couple of hex nuts.

 

DSCN6607.jpg

This is the Line Assembly, Combat fuel pressure system check valve to tee. Whatever that is. .015 rod

 

More below.

Firewalls, oil tank, and fuel line assembly attached to fuselage.

 

DSCN6611.jpg

Another angle. I sure wish these were in focus.

 

Well, that's IT! With the deadline next week and I knowing I won't complete this build by said deadline I've decided to put this aside and torture myself until I complete the K-4.

 

Many, many thanks to everyone for looking in, your continued interest, and wonderfully inspiring comments and compliments.

Until next time. May the force be with you.

Sincerely,

Mark
