787 throttle for 737

[jackpilot]

Just to wet your appetite, this is the main axle for the 4 levers...
I am starting the assembly, based on the 787 throttle.


this is a "paste up" of the 787 throttle in my 737.

Woot..  Looks nice..  *DROOL*

Ehem..  though shouldn't you be working on a shell and liners to show us before a throttle quad??  LOL   

[jackpilot]

I know...matter of logistics.
The MGB has to go first.
In the meantime...

Very nice, Jack! More photos please!

UPDATE UPDATE
I know...it is going slow but all parts start to line up and will eventually come together.
The big item were the 3/8" aluminum levers. Most shops asked around $300 to $400 to laser cut them. Finally a HVAC shop cut them today for $25. Worth being patient.
I can handle the finishing/polishing.
BTW: I will NOT use the 737 knobs  (+the fuel cutoffs) , They look too small for this design, selling the lot for $25 +ship.
The flaps and spoilers ones I 'll use.

This looks great Jack. Very good job!

Btw, I will like to buy those knobs from you. I have some from Padraig with faults, so hopefully the ones you have is allright

[ivar hestnes]

They look better than mine.

I will buy them from you.
I will send you my info in a PM

Fantastic Jack..  Looks like waiting proved to be worthwhile.  Great stuff.

[Bob Reed]

Very nice Jack. I am looking forward to watching this come together....

[Trevor Hale]

Frigging Stunning.. I love it..  Good show, I can't wait to see it work out either.

[ivar hestnes]

Absolutely top notch. This is looking good Jack. Keep it up

That throttle arm is outstanding. Very nice!

[jackpilot]

Thank you guys.
Working with aluminum is not easy but rewarding.
Will post as it goes.

Reversers with their mechanism...
When reversers are pulled back they lock into position and pulling again let the levers return to stowage position by spring action.

[Trevor Hale]

Did you borrow one of those from my screen door?  LOL.  Good usage of Hardware components to achieve such a task.  Ingenuity at its best.

Actually these are used for kitchen cabinet doors....hé hé hé !
I used them on my previous TQ and I bet they are good for several million cycles!
Add a microswitch and Voila!

Those are great looking parts. If I ever build another, I'm going to have someone cut mine too. I cut six identical pieces for the main throttle levers out of 1/8th aluminum with a jig saw.

[jackpilot]

I tried jig-sawing, especially 3/8...disaster. I was close to buying a band saw but found that guy who cut it for peanuts. Well, I spent most part of today filing ,sanding ,steel wooling, but the results are worth it.
Actually alu is fun to work with.
Mike what you did is amazing, I can testify today!!!
Cheers Guys

Keep those pictures coming, Jack! Well done.

Today's pic....
Good thing I do not put a value on my hours!!
I ordered two Clutches for friction. These can be used as a break and allow a very smooth action. Torque can be adjusted up to 13 pounds.
Very nice people:

Wow i missed this one, Jack that looks stunning, very impressed, like the reverser mechanism, will keep that one in mind

[Boeing Skunk Works]

Man those look great Jack! I mean really GREAT. I love the look of fine cut aluminum aviation parts. Almost like a work of art.

[jackpilot]

Basically hand made...Tons of filing, sanding from coarse to fine and finishing with steel wool. After that it takes a lot of care to handle the parts for drilling or installing hardware...anyway lot of work lot of fun... Thanks mike.
Speedbrake and flaps lever are done, soon the TQ box will start, metal too.

How much were those clutches? I think I'd have a problem trying to install one on the #2 throttle shaft. Please post pictures when you get the clutches mounted. I'm very interested.
