"Spook" can it be done? - Page 4 Empty Here are the rib templates that I have

Post  happydad on Sun Nov 01, 2015 2:48 pm

All: Here are the rib templates that I have. The Top one is what Ron and I were going to use at first, but we thought the chord was too thick for a TD .020 engine and I thinned the chord to the bottom template. As you can see the top template is the same as the wing profile so you would have to thin the rib the thickness of the sheeting on both sides, usually 1/16 inch sheet balsa. The 2nd idea was to use a 1/4 inch triangular balsa piece for the leading edge and shape it for best wing profile and use 1/16 inch balsa sheeting on the trailing edge and shape the trailing edge as well. In the end we went with a "D" shaped leading edge and a triangular piece for the trailing edge and cut the appropriate amount off the ribs. It was easier to slot the leading and trailing edges and insert the ribs than trying to shape both leading and trailing edges to match the profile of the ribs-wing.
NOTE: On the bottom rib template the top shape is more uniform than the bottom so I would copy the top side, then turn the template over and copy the top side, now reversed, to the bottom of the ribs as you cut them. I used a jig saw to cut up to 4 sheets of ribs at a time, reversing the template each time.
   Also note a 1/8 X 1/4 slot shown on the top and bottom of the rib template. I used a 1/8 X 1/4 inch piece of spruce hardwood for wing reinforcement. A 1/8 X 1/8 inch piece could be used to save a little weight.
I also considered using lightening holes or slots in each rib, but it seemed that would make the balsa rib too weak.
Two Cents

Top rib 6 inch X 1 1/8 inch thickness, bottom rib 6 inch X 15/16 inch thickness. adjust ruler accordingly.

the fullsize 24 inch version was for the .049, but Ron C. wanted a smaller version for the TD .020, so I made the smaller rib, and slightly smaller Spook .020 plane.

I have sent the Spook plan to Hip Pocket and it is now on line if anyone wants a copy. I tried to add the Mine Nemesis but Ratz says that model airplane news is still selling the plan. I have another practice 1/2A plane that was in the MACA news letter years ago and I will send that one to Hip Pocket if I can find a copy. It was actually a better design than the Mine Nemesis.

Ron C. and I both have fullsize drawings of the original Spook. The plans are roughly 4 x 6 feet. If any one is interested I can scan portions of the plan at 8 1/2 X 11 inches or 11 x 14 inches and send the files, or I can send you the original print ONLY if you promise not to build over the plan. What I did was copied each section I was working on, cut and pasted the 8 1/2 x 11 inch sections together and put a layer of waxed paper on top and built over that.

This is the email I received from Steven Fauble...

"Please feel free to send this around to the rest of the guys that are interested."

Along with that note was a copy of the 1/2A Nemisis plans. Pretty sure Steve is the designer so if he is willing to share the plans then Hip Pocket shouldn't have any beef about it.

Yes I am the designer of the Mini Nemesis but I think Ratz does not want any hassle. As I said the Whetstone MK IV is a better flying plane and I hope that it will be up soon. I had a Sickle F2D design that when scaled down made and even better design but I can not find a plan so I guess that 1/2A will remain unpublished.

Well, don't I feel dumb now Embarassed

I think I understand a little better. I guess it's not a big deal as those who want the plan will still have access.

I just added the plan of the Whetstone IV to my gallery. It is not very clear but if you Right click and "save as" somewhere on your computer it becomes clear. The ribs tail and stuff are full size with a dimensioned drawing of the plan form. It does tend to come out tail heavy with a teedee so keep the aft end as light as possible. I had machined some brass spinners and that helped with the CG on all the combat planes.

Yep, got that, many thanks! The photo-construction is a great help too, it's been a few years since I made any balsa-dust, so I guess I'm back on the learning curve again.
