Ok Steve, i will start working on it in the morning as it seems tomorrow is last day for good working weather at 13Cs and then it's down the hill from there in snowy weather. I will keep you and all posted as i go along with this rebuild. I go machined fibers to make the paste from for applying after layering up the cloth to smooth out the finish.

Such a beautiful morning was today, took the Arrow out, set it up and before i knew things started to happen!, so now just got conformation that dad has medical appointment at 1pm so had to wrap up everything again and brought the model back in side...what a waste of such a great almost if not the LAST good day to work outside.....[][]

Yesterday i also made for former to be placed in the rear fuselage under the fin area, i want to have some rigidity in that area plus a secure mounts for the thrust tubes also before they get attached to the exhaust nozzles...

Props4ever

Last night i was about to start cutting the cloth to the size and shape needed. Upon final inspection of the foam plug/mold i noticed gaps between the foam and upper parts of exhaust nozzles. I used light weight Spackle on there to fill the gaps and build if up for smooth fabrication. Sorry no pictures of this step. I will see how it dried up and if it needs more filler build up i will do it.

I want to give full credit to my friend Mike Emilio for introducing me to this great filler while we were working on my Super Connie model. If it wasn't for him, im sure i would have been using some other filler that would have been on heavier side the light weight Spackle!..

Very much appreciated Mike, Thanks Man!!....

Props4ever

Filling still is going on, hopefully later tonight i will be able to cut the 1st layer of 4oz cloth to the size and get my Aeropoxy resin ready for mixing..

Props4ever

Finally filler dried up enough that i layed first layer of 4oz cloth on the area to be fixed on the model. I cut the ends bit bigger then actually needed, this way cloth can stick better on the fuselage. After first layer i also went and cut 2nd layer to do the build-up.

Mike,

You can see how 1/4scale servos were initially mounted in the wing of this model. There are 2 of these open pockets on each wing.

Started to sand the old paint off from the nozzles. I used 150 grit dry paper to do this, so far it's looking good. I will do the other side of fuselage also and take off about 2" of the old white paint off so resin adhesion would be good and strong bond can be achieved. I couldn't sand off some of the sink areas as then i would had to fill those areas up first before i could start laying up the glass.

Props4ever

All ready for final sanding now, will start glassing it later tonight or tomorrow.

Fiber glassing Plan:

Resin: Aeropoxy Resin PR 2032
Hardner PR 3630

I will be using layering process on here starting with center flat section between fuselage and nozzles.

Seems as working inside <> out is way seems best for the fiber glass lay-up. Will keep layering until enough thickness is achieved for new section to blend in with original fuselage and nozzles.

Today we can say we have 5cms of snow on the ground presently!, Our first day of snow accumulation on the ground in Mississauga, Ontario.

I went out to snap few pictures around sunset time or just prior to it, here is how it was settling on the ground then....

Props4ever

Well im being a weather man tonight!!

I just went out to see the snow conditions, i hate to say that we are under first snow storm sort of!, it's no more 5cm that on the ground as we mare more accumulation now and it's still snowing here in Mississauga!.

Accumulation is almost close to 3" here on the ground and top of my van, i checked it with my ruler....

It's 00:01 hrs here atm....

Props4ever

Sanded sides of the fuselage more with grit 80 wet and dry paper, i could see some old sinks being filled by another filler in past at few areas. I also should have glued the forward filler piece with main mold before but it's being done now, my Aliphatic resin came in handy this time...

Props4ever

I will start with layering up process starting with 4oz cloth first. Work will start from forward missing section towards back and then wrap around both sides towards top sides of both nozzles as airplane is presently inverted.

Stay tuned for pictures...

Edit: Adding pictures now @ 2:03Am

First mix of the Aeropoxy resin after sitting for a year!, still good to use.


Instead of laying cloth first and then applying resin from top i applied light layer of resin on mold first then added cloth to designated area and then applied more resin from the top to fill the weave using old plastic card. Since i had mixed enough resin to do whole section i continued all the way...(Over view)

The end for first applied layer..all used!!

Layering up process is started, i just added another layer of 4oz cloth.
You can see first cloth was sat on the area where it would be layered then i conformed it to all the curves first by hand then with plastic card to make sure all compound curves are covered. Once that was done i did the trimming all around so cloth would be right in the area where it should be.

Then i mixed up another batch of resin, took 3 mins mixing in properly and once it was thoroughly mixed i started to apply it with to are cloth from inside out but before i did that i actually applied resin in the flat center section by making sure both edge weaves are filled before moving upwards and wrapping around the nozzles.

Props4ever

Soon as this layer cures fully i will add another layer of same 4 oz cloth and then i am planning to mix resin with milled fibers to make nice thick structural paste and apply it like peanut butter on top and sides of both nozzles. Once this paste is liberally applied and then let to fully cure, i will sand it into nice smooth round finish.

Now my question is for the followers of this thread. Should i apply 3rd layer extended on all edges then the area to be covered or do it like 2nd layer and just fill needed area?....

Btw that small air pocket on the left compound crease of the center flat section is now gone, i had to make light slit and add bit more resin to fill it.

Props4ever

It's well over 24hrs since my application of second layer, i will apply 3rd layer today at some point and once it's fully cured i will add paste of milled fibers and then let it fully cure before i would sand all smooth into nice even finish.

I thought I would send to you a picture of what I think is an Aero taken at an airshow at the CNE grounds in the 60's. The photograph was dated Oct 1962.

Hey Kevin,

Thanks for posting picture of Avro Vulcan for us all to see, i have heard that these Vulcans used to fly directly from UK to Toronto for airshow and fly back without refueling or stopping here at Toronto, now how far this is true maybe you could elight us on it, but none the less its beautiful picture of Vulcan climbing out at approx 45 degrees!!...

Sam

Sammeer has it, it's a Vulcan as seen in the Faulkland Islands.

They would land, rest, refuel at Toronto International (now Pearson) Airport (YYZ), like most of the really big jets at the Toronto Air Show.

Seen it many times. I'm not old enough to have seen an Arrow fly, and may not live that long.

Props4ever

ERIIIIIIIC

You are the MAN!!, yeah that is what i thought of too but our mutual friend
had a different story so thought i'd ask, mind you Vulcan is all wing and a HUGE one too so they do have the range but constant trip non-stop...hmmm

All kool here DUUUUDDDDDEEEEE...

Hey Eric,

What do you think of my fiberglass job so far, any plus or minuses?

ergocentric

One oddity I noticed is that you cut the glass too short to cover the whole patch, I would imagine the point of this excersize is to built a strong aricraft, and you introduced a joint, and you are allowing the composite to cure in layers instead of making one solid structure. It may peel apart under the stress of flying. in my opinion you should have spent another $70 and vacuum bagged it.

Props4ever

You are right with second layer that i did cut it to match just the needed area but not to forget that i still have another layer to put on this one and i am going to cover larger area then required as i did with first layer.

As for Vacuum bagging is concerned how can i do it on this already built fuselage?, i can't bag this section in it nor can think of a way to bag it and fully seal it!. I have to admit that i am not aware of any hand pump type of equipment to this job either, now i know from the picture you posted.

ergocentric

Um, the glass does not cover the needed area in the photo, what about the front of the v-cut?

The way you are doing it you will have a weak spot straight across the fuselage.

Concerning vacuum bagging: stronger and lighter when you get about a 50:50 ratio of glass to resin, and no air. Without vacuum you have too much resin and less strength, fine for a boat.
You could bag it by putting putty all around the area and clamping the bag to it (you'll probably have to make some formers).

Props4ever

The sectional cut in the cloth you are referring to is on second layer of fiberglass, if you go back to post #62 and see second picture and 4th picture and also in post #61 you will notice difference between open foam plug and glassed over foam plug, now being said that i don't think a second layer with that cut would matter as the part in front of it is also glassed by second layer, this makes full layer and now i am looking to put on larger 3rd and final layer from outside before adding milled fiber putty on this area. I am positive it will be strong as there will no pressure or stresses of anything in this area.

I am also thinking on lines of leaving thin layer of foam on the inside and then glass the entire area with single layer also, this should really help strengthen this part of the fuselage
