737 Throttle Quad

[James Twomey]

Hello All,

After viewing all of they neat throttle work on this site, I have decided that I want to tackle making my own 737 Throttle Quad. However I have no Idea where to start, especially with any drawings. Anybody out there have any good drawings or web site with good drawings and instructions on how to go about it?

Thanks All

Regards,
James

Hi James,

I could describe the building of my quad but it would take a week to type, check out the pics im my album there is a lot of detail revealed there.

I can help if you have specific questions.

Same here. I used very few drawings, sketches really, of ideas I had at the time that I didn't want to forget until I could get to the shop.

I did most of the layout work using measurements sent to me by owners of the real 727 throttle.

A throttle consists basically of a number of varying sizes of bulkheads assembled together with a common axis for the throttle shafts and then skinned in some fashion. There are a thousand details and everyone's throttle is different.

If you need specific component information, please, by all means ask.

Pictures, and lots of them from every conceivable angle will take you miles. The longer you stare at them the more ideas you will discover for building your own.

There are a couple of shots of mine during the build in the gallery as well.

Gwyn,

I believe that you are the principle reason that I have decide to take on this venture!!! I really enjoyed looking over your work and inspired me to teach myself about Potentiometers and Servos and applying them to the TQ. That is an area that I have not a clue about, so this should be a good challenge and learning experience.

Besides, after what I saw a complete powered 737 TQ was going for, I about fell out of my chair and thought that I should be able to figure this out. (with some help from the friends here at Mycockpit.org)

James

Yeah that's the way to go, if I was to build another quad I would use the "sandwich plate" assembly method. Mine is overcomplicated, I got a bit carried away I think! I'm not sure about the timber lever handles, white teflon looks a heap better. I can produce lever handles and might be offering them for sale soon.

That's the same way I built mine, except that I used a ot more aluminum than the other guy. Especially for the throttle shafts and other levers and such.

After looking at several pictures of Boeing throttles in various stages of dis-assembly, I figured if it was good enough for Boeing it was good enough for me.

If you don't have the skills or the time you can go this route http://www.symulatory.com/english/pr...g/throttle.htm . I also heard that http://www.flightdecksolutions.com/ is coming out with one but haven't seen an ETA yet. They also have a couple of nice throttle tutorials on their tutorial link http://www.flightdecksolutions.com/view_tutorials.php. You can also maybe get some ideas from this guy http://www.hanskrohn.com/BuildingTip...o_Throttle.htm . Here's an interesting thread where Phidgets cards are used to run the servos for a home built throttle system http://forums.trossenrobotics.com/showthread.php?t=883 .

Hi,
If you want to make your TQ4 yourself, you can find some ideas here
http://www.737ngproject.be/throttle.htm - probably unfortunately in French (There are even CAD files)
I just have the impression that the dimensions are not quite right, but you can adjust that by looking at some other sites such as

Succes
