dirk tinck Posted February 13, 2021 Author Share Posted February 13, 2021 Hi all ! It seems like , the more i finish items , The more i find other things to do before moulding ... Fitting the motor hatch , i thought it would be better to put on the bigger radius on the hatch now ,and sand it together with the fuse , to blend it in completely. x Here you can also see , all the panel lines are sanded away or filled. These were made on the pss mould with the tape system. They will be done on the new mould with the engraving tool for a more realistic vieuw. x x 1 Quote Link to comment Share on other sites More sharing options...

dirk tinck Posted February 15, 2021 Author Share Posted February 15, 2021 Hi all ! With everything sanded to the right shape , there's nothing left to do before the fine sanding can begin , exept...the panel lines !? There is about 20 meters to do , so better get started ! I used just about everything to get them right : the dremel tool , saw blades , needle files , U name it !! They are a bit deep for now but primer and paint will fill them for a big part.After that it's just sanding them to the ideal depth. As you can see there's still a lot to sand ! This is the work done in two hours , so my best guess is , this is going to take a week or so... 2 Quote Link to comment Share on other sites More sharing options...

dirk tinck Posted February 16, 2021 Author Share Posted February 16, 2021 Thanks Dwain ! Nothing more to show than a few more panel lines i'm afraid ! At this pace it's going to take forever ! There is a lot of mesuring involved , so the other side will go quicker i hope ! More tomorrow !! 2 Quote Link to comment Share on other sites More sharing options...
alan p Posted February 17, 2021 Share Posted February 17, 2021 Dirk how do you maintain a constant depth to the panel lines? What depth are they?. Impressive work as always? Quote Link to comment Share on other sites More sharing options...
dirk tinck Posted February 20, 2021 Author Share Posted February 20, 2021 Hi Alan , sorry for the late reply ! The panel lines have a depty of aprox. 1.5 mm but the bottom is often very rough. That's why i fill them with some filler and go over them with a finger , lenghtwise , to wipe most of it out again. This leaves a smooth finish and all i have to do is give it a little sanding with sand paper wrapped around a sharp , thin knife or a toothless saw blade. That's the easy part...The most dificult , is to form the lines on the round surfaces. This is how i do it , in a few steps : First i draw the lines with a pecil Then i place a double sided tape along the line . I use double sided tape for its thickness ,so i can follow it with a sawblade and ''cut'' the first time.It's very important to get it right the from the first time , because the saw blade will follow this ''guide'' the next cuts.I repeat this untill the line is deep enough. I also use a sculpture tool to get there (forgot to take a pic). the last thing i do is clean out the line with sandpaper...Done ! I use the Filip Avonds drawings as a guideline in this process...There's like a milion lines to do... x x Quote Link to comment Share on other sites More sharing options...

Nigel Sharp Posted February 20, 2021 Share Posted February 20, 2021 Super impressive! To keep faith I suppose you have to remind yourself one less to do. How do you do the Elliptical one's, compass perhaps? Quote Link to comment Share on other sites More sharing options...

dirk tinck Posted February 21, 2021 Author Share Posted February 21, 2021 Thanks for the comments guys ! The elliptical ones i do with wooden templates Nigel , or flexible plastic drawing tools. these are the hardest to do !! I'm afraid i'm still drawing panel lines ...The ''good'' news is that i'm halfway this process ... Some images : Getting bored with these lines i tried another detail yet to do :some 60 DZUS screws. These were also stickers under paint on the PSS fuse but i'm testing another methode : Real screws ! About 5 minutes per screw , that schouldn't take too long ! Thanks for watching ! x 5 Quote Link to comment Share on other sites More sharing options...
Phil Cooke Posted February 21, 2021 Share Posted February 21, 2021 Superb work Dirk - fantastic to read and see your methods. I like the DZUS solution too - that way they'll all look identical for sure only the 1/4 turn alignment to worry about! Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted February 22, 2021 Share Posted February 22, 2021 Hi Dirk, the conventional way for panel lines like this is with Chart tape and build the edges with primer. Then remove the tape. This model below is at about 1/7 scale but they do wider tape for larger scales. Are you worried that by scoring/cutting into the glass work you are creating potential fracture lines? Cheers Danny 1 Quote Link to comment Share on other sites More sharing options...
dirk tinck Posted February 22, 2021 Author Share Posted February 22, 2021 Hi Danny ! I used the chart tape on the PSS fuselage but... By the time the primer was sanded , the plug was painted , moulded ,sanded , painted again , the lines were as good as disappeared ! I think it's a good system for direct use , not for plugs. I would never trust cutting so deep in a composit fuselage ! I even have spots where i cutted right through ! (with the system i'm using now , not the last pic ) Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted February 22, 2021 Share Posted February 22, 2021 Ahhhh okay i hadnt realised this was the plug, must pay better attention ☺️ Quote Link to comment Share on other sites More sharing options...
dirk tinck Posted February 26, 2021 Author Share Posted February 26, 2021 Hi Danny ,it's propably me , making it complicated ! The panel lines are history ! Well , there might be some forgotten ones , i can always add them. The last few days , i got some hatches done with the dremel tool and templates. I made these out of abs sheet which is easy to cut and sand and is also flexible to follow the round fuselage shapes. After sticking them to the fuse with double sided adhesive tape , the hatch outline is milled in the epoxy. The bottom of the lines just need a little cleaning up to get a smooth finish. After primer and paint they will have the correct depth...I guess This is going to take a couple of days ! Quote Link to comment Share on other sites More sharing options...
dirk tinck Posted March 5, 2021 Author Share Posted March 5, 2021 Hi all ! I'm not used to skip 5 days without posting some progress here but i don't want to bore you guys with the same pics every day... This evening was hopefully the end of 3 weeks engraving panel lines. Just the dummy screws to add before prepping for primer. Some of the lines need some repair too , as it doesn't always goes as it should ... 5 Quote Link to comment Share on other sites More sharing options...

dirk tinck Posted March 8, 2021 Author Share Posted March 8, 2021 Thanks Ron, It doesn't look like much progress , but i just finished 106 dummy screws on the fuselage... The big clean-up can begin ! They are not glued in yet , primer and paint would make them less visible so that's an'' after paint'' job when their seats are re-machined to the correct depth. 2 Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted March 9, 2021 Share Posted March 9, 2021 Lovely work Dirk I am sure you will have close-ups of what you are doing, so forgive me if I am wrong but usually straight slotted screw heads are DZUS fasteners and not actual screws. As you will know a DZUS sits at an angle perpendicular to the panel, so when observed they all align, a very quick way for the maintenance crew to know if one is not done up is to look for one not aligned. If a screw is used it is usually a cross-head. Cheers Danny Quote Link to comment Share on other sites More sharing options...
Stephen Jones Posted March 9, 2021 Share Posted March 9, 2021 Don't say that Danny, You will have Dirk fill them in and start again. ☺️ Steve. 1 Quote Link to comment Share on other sites More sharing options...
McG 6969 Posted March 9, 2021 Share Posted March 9, 2021 No worries about "filling them in and start again", Stephen. Dirk wrote that they are just a dry fit so far. But Danny's right as Dzus fasteners are a 'quarter turn' and the underlying spring wire is always - read 'preferably' - fixed in the same 'orientation', making the 'closed' Dzus slot appear all in the same direction. Mostly 'horizontal' on a fuselage, but not always... Cheers & stay safe Chris 1 Quote Link to comment Share on other sites More sharing options...
