IMAC Dalton 300 ml build thread.

here is where we are now, just glued in the tabs!! hey, be careful here not to glue both halves together.

i put the tabs in so that the wide part goes in from the top, apply a little Hysol before getting it down further, then move tab all the way back, and finish putting glue all over the tab rectangle.make sure to again check that the tab is pushed all the way back.  i then clamped this together.

just got back from Boston! i tested the cowl set up and did a trial fitting on the fuselage, and so far. all looks good...

 i still have to mark all of the hinge points, the servo boxes, the hard point locations, etc... Then, i will glue in hard points and drill out the holes for the point hinges. i have to cut out the servo box areas.  

 

once the hinge point holes are drilled, i will then have to core out the foam to create a tunnel for the servo box. i am not using a traditional round hard point. Instead, i will be laminating 1/4" plywood blocks to fill the area from the top to the bottom of the elevators, then sand flush. I am also going to use the metal control horns instead of the screws thru the hard point.

That is the slickest cowl set up ive ever seen, jealous, I have like 7 bolts and t nuts each side, looks perfect . Good work.

i need help with a project.  i want to find out what is the best way to cut the canopy, so that the cut is super straight, smooth, clean?

 

should i outline the area with masking tape to make a straight line?

 

but then, what do i use to cut it with?  dremel cutting wheel will not be a clean cut.  scissors also are not straight???

 

what to do??

I use a sharp tin-snips like this one:   Snips

Get it the best I can then use a sanding block with sticky 180 on it to smooth out any imperfections.

Second the tin snips ! Tried everything on lexan, tin snips cut cleanest.

Cant seem to find it but I cut a groove in a wood block both sides and sticky back sandpaper lined it, rounded and sanded the edges quite well, small block, like inch by inch half , one side 180 other side had 400 to finish but not necessary.
