Hi Jeff,

The template I am looking at is the M series 4&5 in the Cozy MK IV Third Edition plans.

G'day

 

Steve - I'm not sure about your drawing. Where in chapter 4? I am building from the Open EZ templates and Terf CD and don't remember that back in chapter 4. I have finished 4,5,6,7,8,9,14 and will finish 10 in the next couple of weeks. Please point out where the picture you posted is in the plans.

 

Thanks, because I don't remember it.....

PS - Saw the discussion on last-a-foam. I am using Divinycell H80 instead.

You can get all the foams from Nupol here.

Hi All,

Just wondering what your opinions are on the M series templates.

I am almost at the end of CH4 and cut the foreward landing gear bulkhead last night..

I used the written dimensions from the templates to draw out the shape with a pen on the foam rather than trace the template. Admittedly this took a lot longer than expected but was concerned about accuracy. It turns out once I was finished and had cut out the shape it was too short horizontally !! This means for sure that I had errored somewhere.I basically used the measurments as noted from the the centre line -> RHS and then duplicated symetrically. So what gives ? Either the template stated dimenstions are wrong or the template lines themselves are wrong. Any thoughts out there ?

Araldite works great. No smell. Wets out very nicely.

Thanks to all who have replied !

The Resin decision has been made. After some discussion with Peter Karanges (SAAA CH 15 President and T.C.) we reckon the best way to go is the Araldite K3600 System. It's tried and tested in Australia on Jabiru Aircraft and will more than likely always be available for the life of the build. Details are as follows:

Supplier : CG Composites - in Hendra, Brisbane (Scot Hood)

Araldite LC3600 20kgs $310.00 plus GST

Hardener 6.7kgs $241.00 plus GST

Total: $635 inc GST with delivery.

Should be here tomorrow which means I can get back to work on the weekend.

Post Cured Properties :

Glass transition (oC) TM22 90 DegC

Tensile Strengh (N/mm2) TM48 70

% Elongation TM48 3.5

Flexural Strenth (N/mm2) TM46 102

Flexural Modulus (N/mm2) TM46 4800

Does anyone know what TM means ? as in TM22, TM48, TM46 ?

My latest discoveries :

ATL Composites - Southport,Gold Coast

-------------------------------------

R246 Kinetix 18Kgs $281.90 inc GST

H128 Fast Hardener 4.5Kgs $148.63 inc GST

CG Composites - Hendra, Brisbane

--------------------------------

Ampreg 22 20kgs $433.25 plus GST

Hardener Extra Slow 5.6kgs $227.00 plus GST

Araldite LC3600 20kgs $310.00 plus GST

Hardener 6.7kgs $241.00 plus GST

Jabiru use the Araldite LC3600, its the top of the range stuff.

Ampreg 22 they uise in Germany for Gliders.

Can't find anyone that uses R246 but it looks good on spec. Good Glass transistion, strength and hardness

Resins in Australia

Hi All,

I have a resin question.

I know that this dicussion has been going on for some time and have read all there is on the forum but was wondering if there had been any development of late with alternatives....

I bought the West 105 / 206 system and started the first layup (started building for the first time yesterday) I thought it was an approved resin for the Cozy as it was listed in the beginning of Chapter 3. On going back to the construction notes in the evening I found a footnote stating NOT to use it for laminating. This was abit of a blow as I have just spent about $500AUD for 20 litres with hardenner. Not to worry I can use it later for other things...

So the question is this ? What other alternatives are there here in Australia ?

1. MGS locally with in Aus.

I know we can get MGS from Ironbark composites but I refuse to pay the monopoly price they are asking and I have heard from various people who have dealt with them that they are not entirely shall we say good to deal with.

2. MGS outside the US.

Does anyone know of any pacific rim distributors ?

And whats the go with getting a HAZMAT clearance to get it into Australia ? is it cost prohibitive ?

3. Aeropoxy

Are there any local suppliers of this stuff ?

Has anyone tried it ? Any good ?

4. Araldite ?

I heard rumours some are using this

4. Vinyl Esters

Was talking with another builder friend who is a very experienced mechanical and aerospace engineer and he suggested Vinyl Ester. They have the same if not better properties over epoxy resin and its a lot cheaper. Has anyone trail blazed here ?

(Derakane 311-350 or Vinyl Ester 470-300)

Any thoughts greatly appreciated ?
