DR-1 (Sands): Builders Group

[Jim Bruton]

Dogtail2, Nice cutting work. I am always amazed how great everyone's work looks. Too bad there isn't a big market for this stuff! I think the builder of the ribs was going to make as exact a DR-1 as possible and even made these ribs in the original, but with the proper and eventual improvements, and perhaps has decided to tackle a different Fokker instead. I am sure that sometime, someone will be perfect for them. Glad you made your ribs! With the spars done, it's like you are over the hump. Now on to the fuselage, so I'll turn it back over to our new fuselage expert, JoePilot. Take it away Joe!

Hello Jim,

is there a way you could post some good overall and close up images of those ribs?

Cheers!

let me see what i can do Achim!

Waterjet cutting for these 4130 parts is actually very inexpensive, and the accuracy is great +/- .002. All that is left to do is cleanup the edges (light buff). The bending and shaping from the flat stock isn't included. I would offer to have some stuff cut; the shipping costs would likely exceed the cutting costs, however the offer is open if anyone is interested.

Completed the cutting and placing of all the tubing for the right side of my fuselage. It is in the jig awaiting welding. Ran out of time to tack weld. Got to fly a 4-day trip, so I hope to tack weld on Wed or Thur. Hopefully I will have my camera back from my college son to post pictures. If this works, then by Friday I will have two fuselage sides and a rudder.

I spent yesterday building my fuselage table, and today began laying out the fuselage lines. But after only a few minutes found a discrepency in the measurements on the drawing(sheet 17).

If stations 28.00 and 40.25 are correct then the 11 13/16" dimension cannot be correct.
(12.25" minus half the 5/8" tubes = 11 5/8")

So my question is ; How critical is the 11 13/16" dimension

[Fokker210]

It looks to me as though these are two different measurements - the distance between stations 28.00 and 40.25 appear to be measurements to the tubing centerlines whereas the 11 13/16 seems to be the actual opening for the spar. I'm not at this point yet so please correct me if I'm wrong, Gents !

Ron made a big mistake on this part of the print. Look back to my post on pg 122 post #1212. The landing gear needs to go where that front vertical 5/8 tube is placed so on landing the V shape takes the force. Also the little angled tubes that connect the V tube to the longeron should go to the sleeve that the wing mounts to. What I am saying here can be confirmed by looking in the wind sock data file on the DR1, there is a picture of an uncovered fuselage which shows these corrections. Also remember that these tubes will only get added after you mount the gear and mount the spars.

Dogtail2,
If you check the width of the spar at this point, it might give a clue
as to what the proper dimension should be. I'm not familiar with the whole
plan, so this is just a guess.

Please disregard, Thanks
