737 Throttle Qaudrant question...

[mauriceb]

Maurice,

Yes, I actually did check out that site and got some very useful information from it. If you notice though there are no measurements for the levers, metal guides etc. BTW, I also checked your site out as well, great work. Thanks for the reply.

Ian,

If I can just give you some advice or rather some observations I made, I think you are placing way too much importance in the exact dimensions. In my throttle, I literally took guesses for everything by just looking at pictures from Airliners.net. I did not know about Markus Pilot and I agonized over these dimensions while trying to measure parts of the throttle in the pictures and comparing them to parts with a known size in the same picture.

Strangely enough, I came pretty close & the end result on my throttle is definitely not exact, but it is now more than close enough for me. I don't even think about the dimensions anymore and I really could not care less that they are not exact.

All the handles feel right to me when I use them and in the end, that is what really matters (to me at least). Now, I know that everyone is different and to some, this would be heresy. But I really think Markus Pilot has all the dimensions you really need unless nothing but an exact replica will satisfy you.

That's a decision that only you can make, but I just wanted to point out that many of the things that tear you apart when building will fade away as distant trivial memories once 'the thing' is finished. It did in my case and I can't believe now that I wasted so much time on so many trivial details.

Having said that, if I was to build another assembly of some sort, I'm sure I would still agonize over some details, but maybe not as much now

I used a lot of photos and extrapolation of measurements as well as some dimensions sent to me and drawings by Delta for mine. It's not 100% exact, but it's close enough to fool 727 pilots.

Hey Maurice,

Upon your urging I went back and checked markuspilot's site again, and your right, he indeed does have the dimensions for the levers, not all, but enough so that I can make some decent judgements..... I had actually downloaded dimensions for the throttle stand's height, width and depth from his site and somehow missed all the other stuff. Thanks again to you and all who replied.

Now I have another question regarding the levers.

In regards to the Spd. brake and Flap levers....are these levers somehow spring loaded ie. I imagine they have to be lifted out of the slots on the metal guides. Do they just moves up and down on a shaft manually or is there some kind of spring loaded device built into the levers?

Thanks guys

Yes, both the SPD Brake and Flaps lever are spring loaded in the real AC

Have you checked markuspilot.com? I think you will find most or all the dimensions you need there

This site is great, however, the most of the measurements are absolutely inacciurate. If we talk about TQ, the centre axle positiong is totally wrong. I am making 3D model of the TQ that I plan to build. I have a real AMM - taking some scale drawings from there. Unfortunately they dont match the measurements from mentioned site.

I asked for help from couple of people who's got the real one, but no reply so far.

I asked them to help me with this dimensions.

The schema or the 737 classic TQ, not exactly NG type. Its slightly differs from NG with levers design. All the rest is pretty much the same.
In fact to complete my drawings I need to know only trim wheel shaft position against TQ body. With this I can calculate the rest from scale AMM drawings.

Notice - TQ upper-down view is not the box shape! Most of commercially available TQ's costs a fortune, but the level of realism is far from desired - those are box shaped.

Speed brake lever is spring loaded in the lever assembly. But speedbrake detends are loaded in the forward speedbrake drum (connected with lever by 2 rods) on arm detend and flight detend. Off position is fixed by the lever in the forwardmost position.

If you show me a drawing of what measurements you want i can make pictures of my throttle.

Please take a look on the picture. The dimensions 1 to 6, but 2,3,4 are the most important.

Better quality here http://picasaweb.google.com/vitabutc...54196456413250

Btw most of the TQ's I've seen in the projects doesnt have 5 as zero.

Cheers, Vitaly

vitaly,

i will make the pictures tomorrow and post them here.

You seem to have the maintanance manuals. Do you have it in electronic form ? I would love to have a copy of the throttle part. Will help me alot taking apart and motorizing my throttles.

This is quality work. Compared to mine anyways. This gentlemen did a Awsome job. The metal work is impressive

Everybody here has done great TQ work.
