Phil Cooke Posted June 2, 2019 Share Posted June 2, 2019 Superb work Dirk! The methods and skills demonstrated in how you're ably applying them is really impressive to see explained pictorially like this - we do have some serious talent within our ranks here that's for sure! I'm looking forward to seeing how you join and reinforce the 2 wing halves! Quote Link to comment Share on other sites More sharing options...
dirk tinck Posted June 6, 2019 Author Share Posted June 6, 2019 Thanks Bob, Steve and Phil for the nice comments,i really needed a little boost after a windless PSS weekend in France.Driving 1600km to put a electric glider in the air isn't funny at all. Not much new to show ,exept for the 4 flaps en ailerons being ready to take on the second half of their mould. Quote Link to comment Share on other sites More sharing options...

dirk tinck Posted August 12, 2019 Author Share Posted August 12, 2019 The last image shows the root-side ready to mould. This will be the last of 22(!) moulds for the wings. the reason it took so long was the high temperatures we've had the last few weeks,up to 41 °C. It's impossible to work with epoxy at this rates so i had to wait till late at night to start laminating. It's in the twenties now so i can move on.Just a few day's and i can start making wings : FINALLY. Next post will show the whole of the 22 moulds. Stay tuned and comment please! That's what keeps me going ! Quote Link to comment Share on other sites More sharing options...
McG 6969 Posted August 13, 2019 Share Posted August 13, 2019 Still there and watching, Dirk. It's amazing how many little bits you have to prepare and mould, but I guess you'll be rewarded soon now. Looking forward to seeing your first results leaving their moulds... Cheers Chris Quote Link to comment Share on other sites More sharing options...

dirk tinck Posted August 13, 2019 Author Share Posted August 13, 2019 Hi all ! Another evening in the shop and mould nr 22 is a fact! Next step is to reinforce here and there , bolt everything together , clean-up the edges and get that wing out ! Quote Link to comment Share on other sites More sharing options...
dirk tinck Posted August 15, 2019 Author Share Posted August 15, 2019 Foto's of the mould reinforcements.To prevent the mould from warping i placed some wooden scrap over the wing.They're glued with some epoxy mixed with cotton flakes to make it less liquid.The fillet is then covered with 1 layer of 200 gr glasscloth and resin.Strong as hell when dry!! The reinforcements also serve as a support when the mould is upside down to form the actual wing(to prevent a warped wings) Quote Link to comment Share on other sites More sharing options...

Stephen Jones Posted August 15, 2019 Share Posted August 15, 2019 My word there is a lot of work involved in making these molds. You have shown some patience and dedication sir. Steve. Quote Link to comment Share on other sites More sharing options...
SR 71 Posted August 16, 2019 Share Posted August 16, 2019 Truly superb Sir, i have built one jet using this method, very dificult and not in the same class as yours Ill change that remark, not even in the same school Thank you for showing Tony Quote Link to comment Share on other sites More sharing options...
Reuben Saliba Posted August 16, 2019 Share Posted August 16, 2019 The thing that always amazes me is how does one work and take photos at the same time. Epoxy and cameras do not mix otherwise there could be a second person taking the shots who has clean hands or gloves. I do make this stuff as well but am unable to work and take photos at the same time as I do not have anybody assisting me. I usually take photos after a session is done. I truly understand the "pain" one goes through in making a full composite model but in the end it is worthwhile as copies could be made in the event of something happening to the model. Very nice work! Reuben Quote Link to comment Share on other sites More sharing options...
Chris Freeman 3 Posted August 16, 2019 Share Posted August 16, 2019 Very nice work. When you see the amount of work and materiels it takes to make the moulds you have admire the commitment to making them. I had a little involvement with a P51 and I think I would rather stick to using balsa. Quote Link to comment Share on other sites More sharing options...
