737 Throttle levers

[Steve A]

I have started my home build throttle and have been searching across the net for various parts i can purchase, This is so i can save a little time with the build but mostly because i just dont have access to the certain tools needed to do a high quality job.

I have sourced throttle knobs and handles from a few suppliers but what im really looking for is the actual Throttle levers, They are quite intricate in shape and i would be kidding myself if i thought i could be happy with what i could make with the tools i have.

So do any of you guys know of a supplier or even a freind here who would make them for me?

Thanks Steve

Have checked out some of the throttle tutorials http://www.mycockpit.org/fileshare/showentry.php?e=31&catid=27.
All you really need is a jigsaw, a file and a drill. Easier then you think.

Another option would be to give the CAD drawings to a fab shop with a CNC machine and they could cut the pieces out for you.

I'm sure some nice person will help you with a supplier....but don't be too hard on yourself.
In the dark early days, i used the cad drawings that float around to cut handles with a jigsaw.... then filed them and sanded/primed again and again and again.
a router is also handy to sink the micro switch for the reverser's too.

you will get them absolutely perfect. might take all weekend though.

then you deserve a nice cold beer.:)

Thanks for the encouragement and link to the tutorial and drawings. I just need a link to drawings for the levers now and im all set to start cutting ;)

Edit found what i need

[Geremy Britton]

Steve, So your building one yourself then!

I wish you the best of luck and i'm happy to provide you with the resources i have. Although this isn't my work i don't take any credit for it. Someother kind person has both this together. Look at the pictures and also the PDF attachment at the bottom for some dimensions. once again i have no claim to their accuracy though.

Enjoy :) :)

Hi Steve,
Here's a pic of the workings of the levers I made...

The real thrust levers!

Geremy, those pics are of the 767-400 TQ not the 737, and the PDF is for the number 3 lever for the 747-400 TQ, i know i did it :) just so no one gets confused.

I was bored so gave it a go also, based on bits of measurments floating around on the internet so I CANT BE 100% SURE OF ITS ACCURACY, but somthing to help you along

autocad 2D of one of the levers, and a 3D .IGS file of the same lever, ohh and a picture.

Must i must stress again chaps, it wont be 100% true to the original, its just to give you an idea and somthing to play with :)

Enjoy

Fantastic response!!

Strangely a workmate offered to sell me a router today, so its all systems go :mrgreen:

[Geremy Britton]

It certainly is! Plenty of stuff there for you to make a good go of making throttles. Must be a good response because you're builder of the month. Lap it up whilst you can ... 7 days left until your succeeder ;):p

Live up to the name ... builder of the month... go ahead get building! :mrgreen:

LOL

I could do with just a little bit more help before i dive in.

I want to use slide pots but im a little confused about how to physically connect them to the levers, all i can see from pictures is a little square tab on the pot. Does anyone have a picture or drawing?

If it's this method you're using:

Download here:

it looks like a bearing from a roller skate or a small metal cylinder running in a groove up the shaft of the throttle. It works in much the same way as a piston in the cylinder of an car's engine.

If it's this one:

it looks pretty self explanatory and quite elegant if I say so myself.

Good luck :)

the link is dead any other links for the throttle tutorial

[Buddym]

Great tutorials! Does anyone have a link for similar tutorials for the A32o throttle units?

How are your levers? I was planning to cut them this weekend from mdf, .. but I too am convinced that I won;t be able to make them properly. I recently bought a 2nd hand electrical scroll saw but I canl;t seem to cut a straight line with it.

Someone should introduce complete throttle levers to a collection.... I think they'd be a good seller. Oh well,... back to the shed I guess ...

[Steve A]

Yeah i searched the world for the lever's.... i even emailed some manufacturers to see if they sold the levers seperately. These were the biggest reason i didn't want to start my throttle because of the complicated shape and interfacing. In the end Jackpilot gave me his prototype's, they are generic with a swing toward boeing and they are awesome, made from aluminium. Good luck mate.

[mariodantas]

Yeah I've the same problem, the f*******ng throttles, would like to find an autocad file to bring it to a friend of mine wich works in a big enterprise who works with big CNC machines and could made me an aluminium throttle.
