My Fokker DVII Project

I need to confirm, but isn't the available Parker Steel St.35 and St.52 similar to the 1020 mild carbon steel that was used on the original Fokkers? We don't really need 4130 steel, do we? I know its stronger, but is it really necessary in a Fokker design?

I have to jump in here and support ulpilot. NEVER tell anyone that you want something from, that you're working on an aircraft. If you need engine services done (say having pistons cast), or buying supplies like steel or hardware, never say the word airplane -- they will shut you out in a New York minute just for fear of lawsuits. I always tell people (no matter what I want) that I'm working on a boat. Boats for some reason inspire people to help rather than run for their lives (or lawyers).

And NO -- do not try to use 4140.

And No, you don't really need 4130 either. It wasn't available in WWI and almost everything was made from simple low-carbon steel. 1020 steel should be adequate for almost anything, if you're building to the original design. And the European steel of that time varied quite a lot in carbon content. You would probably still be safe even with 1015 or 1012 steel.

I've never heard of having a problem buying from Parker Steel. But, in any case, I have an account open with them and will gladly order what you need drop shipped to your address. Just let me know if I can help.

Thanks for the support Spadmaker, I've run into problems myself because of that nasty "A" word. Boat,tractor or antique furniture restoration always open's the door.

Wish I had known you were set up with Parker, my company is too now.

"Hello" ... Yes? ... I need some Steel. .... for what? ... building a ship. ... O-building a ship? ... Yes! ... Whats her name? ... Titanic .... " Click!" ... Hello?, hello?

Yes, never mention the " A " word, I did once, only once.

Also try Maryland Metrics:

I have been working on the control column. I made these triggers, but I am stalled on the auxiliary throttle mechanism. My plans don't have enough details to get one machined. If anyone had info they could share, I would appreciate it!!!

P.S. Scott, Ross ... I'm not a big fan of this new Photo format either ... can we go back to the old method? It took me FOREVER to figure out how to post these photos and now they look SO small after they are blown up!

Hi Jeff,

If you can wait a week or so I will scan and post up the detail for the aux. throttle housing from the sands drawings. Got married yesterday and off on honeymoon so dont have time right now but will do it when I get back if no-one else has.

Jeff,

We happen to work on the controll grip as well and seem to miss some vital details. What drawings do you work from? Ours are the Dick Funcke ones.

I am using the Kiger plans, and an original Fokker drawing (I believe) #51119 and No 51093a. they show the part that is used to attach the Aux throttle, but that part isn't drawn out with dimensions ... just numbered as a part. then there are not drawings of the aux control mechanism. the funcke drawings give me outside dimensions, but nothing inside. i'm sure I could hazard a guess and make it work if I had to.
