Hello everyone I have added pics of trigger breakdown and the painted parts. Need to wait couple days for paint to harden.

 

Please note the cannon trigger retur stop screw and nut is missing.

ITs a #6-28 x 1.5 " screw that will be cut to about 1" long.

Wile I was redoing my post Agrasyuk got my link to work. Thanks , AND even though I removed it, it still works. Agrasyuk Did I make a spelling error? POSTING PICS ARE HARDER THAN BUILDING COCKPITS!

I have been asked for more Info on Trigger . I have started a new one,and can better document the method that I am using.

There will be some changes to the new design . One peice weapons trigger.Slightly larger shaft with steel inserts "bushings" for better ware resistance and a change to the cannon ready switch . untill its finished, there could be more changes, as some times good ideas come before the part is made as aposed to after . The steel inserts are an example of this .

I will post a drawing right away

Here are the cut parts. cannon trigger,leaver arm are allready bent. The cannon trigger was wraped around a piece of 1/4" steel plate in a vice with a hammer.

 

NOTE: TRY TO BEND THE MATERIAL YOU USE BEFORE THE PART IS LAYED OUT AND CUT. very frustrating when it cracks. I found some aluminum just wont work. Keep trying .The older stuff seames to work better.I think they keep rolling it longer and longer to get more and more . bend slowly with light blowes from a hammer, about 40 wacks for a 90 deg. bend.

[Panthro]

awesome stuff!

Bearing installation. Steel tube 1/4" dia., threaded into hole, cut off both sides flush with a hacksaw.

Do this for all 6 holes.

 

Hole placement: ........................................................ FOR LESS CONFUSION MEASUMENTS WILL BE REFERED TO PARTS IN THEIR FLIGHT POSITION.................................. After bending First mount shaft in base . The shaft is horizontally centered on the base, 5/8"fwd. of the back side of the base [mount point].Next mount the cannon trigger.Horizontaly on center {about 1/4" from top]. The trigger rides close to the shaft . looking down there should be a gap [clearance] of 1/8" between the fwd. side of the shaft and the back side of the trigger. Lay the trigger face down on a table and measure from the table surface up on both sides. For the weapons trigger add 1/4" to the cannon measurement. so when viewed from top down, there is a gap of 3/8" between fwd side of shaft and rear side of weapons trigger

needs finihing with a file.

[acemark]

HERE is how the weapons trigger is offset. With 2 scrapes of the same material as the trigger placed on either side of the offset in a vice squeeze real hard. there is a 1/4-3/8" gap between the 2 pieces of scrap. this is where the offset will transition.I used tape to mark the bend.

Here you can see the shaping of the weapons trigger [top] so that it will open wide. The new shaft dia. is still throwing me suprises. NOTE: After bending the legs on the triggers, they may need to be shorter to mount on base with shaft.The cannon trigger legs can be cut short . The inside weapon leg is more complex. The end needs to be cut on a radius from the center of the shaft bushing.The length of this leg is 1/8" short of contacting the base when weapons trigger is lifted.The outside leg wont need any trimming. A drawing will follow. MARK.
