Cutting Nose Gear Well

I cut out the nose gear well using a razor saw and flush cut saw. My kit did not come with nose gear doors and I'm not sure if there are any. Larry is looking to see if there are some in his kit parts. If not I will use the nose gear well cut outs as doors so I wanted a thin kerf so I used the razor saw instead of the Dremel cutting wheel.



The seam line is not the center line so center line was marked after sanding the seam line smooth. I wanted to do the rough sanding before cutting because it would be easier to hold the fuse rather than the small cutout.


Razor saw with pads taped on help hold on to it.


Corners cut with thin flush cut saw


Gear well cut out removed and edges sanded smooth


The seam line is not the fuse centerline. Easy to see on the gun camera housing.

Designing Gear Mounts

I copied the gear mount design from a photo of the kit built by Fighteraces in England. I planned the layout using measurements from the formers that came with the kit that were balsa cores. I then cut fan fold foam parts to mock up and see if my plan worked. Most of the time was spent just thinking it through and drawing. Cutting the foam parts went pretty fast.



Planning the parts layout and measuring existing parts


Side view drawing of gear mount beams and formers


Test fit of mock up parts


Took a couple of tries cutting the mount angle to get the 2-3 degrees forward slant.


Final parts ready for mock up


Gear test fit on mock up. Cutting wood parts s next.

Awesome work nicely done with the build documentation. I still can’t believe Joe Grice let one of these birds go.

LOL..feels like master hacker, not the computer kind. Thx. Gary

Just realized I have to plan space for the rear gear door hinges. Will have to make a relief cut out in the beams for them. Also a biggie is the ground pitch stance. I’ll have to put in wings and check to make sure there is a neutral or positive pitch attitude on ground before I glue in the nose gear mounts.

I've looked at lots of Bob's videos lately. I'm really glad he documented the build so well.

I only came across his YouTube channel while watching random videos about glass (crash) repairs, once I discovered it I think I lost a solid 2 days of productivity to his videos.

I lost about a month - I have seen practically all of them, it is a lot of content. Pretty amusing too.

Finally got back to shop today after finishing all the hurricane Florence prep around the house and got the nose gear mounting templates cut out of wood for a dry fit. I will not glue them in until I get the nose gear door hinges and can determine the size of the relief cut outs for the hinges. The dry fit will allow temporary install of the nose gear for checking the toe in angle of the main gear which is where all the work so far is going.



Rough cuts of nose gear mounts


First dry fit.

Formers had to be sanded some to get correct fit and bottom of vertical rails hand to be rounded to fit bottom of fuse


Nose gear dry fit.

Might be an optical illusion but there doesnít appear to be a lot of meat for mounting screw. Keep up great work. Still canít believe you were able to pry one of these away from Joe Grice

Yea, your correct but the holes are just the pre drilled ones. I’ll drill actual mounting holes later. I just “tacked” the NG in place with existing holes so I can get it on the wheels to check main toe in and NG height for correct pitch on ground.
Thanks. Keep your eyes peeled in case I do something dumb. I can use all the help I can get.

I think I’m actually the second owner after Joe. I know he had five at one time. Not sure what he still has.

No just regular paint and stuff. I'll plan to test fly in primer and then decorate it. Turbine will be a K-310G.

Next steps are to install the wing trailing edge hard mounts. Still working toward getting the jet on the wheels to check the gear toe in.



Projecting the location of the trailing edge wing bolt. The plan is to drill all the way through the wing root to the flap side and install a 10-32 blind nut.




There is a 1/4" gap between the fuse and wing root when the wing is bolted on. I installed a spacer so the bolt will hold the wing firm with out pulling it in.


Pilot hole drilled from outside in spacer location


Wings installed and bolt hole drilled from inside out through wing root


10-32 blind nut installed with bolt


Blind nuts secured with hysol


Wings installed ready to mount gear

That’s a beautiful wall of tools! Keep up the good work. I saw one of Joes in partial FM and by golly that was one gorgeous looking bird.

Cant wait to see yours when it’s done. Fantastic documentation.

Next step is install gear and get it on the gear. Then check the ground pitch attitude and then main gear tow in.



Main gear installed


The gear looks huge, just like the real ones



First look on the the wheels, it sits real tall and the main gear has lots of toe in...bad.


Happy snap on wheels


Ground pitch attitude is slightly positive so the nose gear mounts are ok.


The nose gear strut is slightly forward as planned from the three views I have.


View from the rear


Aligning the fuse parallel to the tables to get a center line to check the main gear toe in


Fuse aligned and centered on table ready to mark the gear toe in angles

I found the main gear toe in angle to be excessive on both sides. Still not sure how to fix the problem yet.


Projecting wheel axle location to table


Marking tow in angle line parallel to tire


Marking line parallel to fuse through the wheel axle location


Measuring angle of toe in


Right main wheel has 6 degrees toe in


Excessive toe in


Left main has 5 degrees


Excessive on left also

After checking the main gear toe in I got a little discourage and and hurricane Florence was approaching so I decided to stop working and make the F-105 a static display for now. This is when I experienced a little scratch building humor.
..


The fin spar blade attaches to a plywood former inside.


OOPS I followed the "instructions" but must have skipped this step...the former will not fit into the tail after the aft turbine rail half former is installed. Note to all you guys building your F-105s don't install the half former until you install the fin former...just in case you wanted to know.


Solution is cut the former in half.


Half former inserted and fin spar clamped on. Good enough to look at for now
