Here's my latest 3D printed pilot, Baron Otto Von Schnorkel. in my 25 year old Magnatilla which I've been restoring to take part in float plane events. He's on Thingiverse if you want the files. https://www.thingiverse.com/thing:2845436

Hi Nev. This is as near as I could find for this. There doesn't seem to be a simple method of sketching straight onto a curved surface but if you follow this you tube vid and replace his text for a blister shape sketched as he shows I think you might have a starting point for the blisters. https://www.youtube.com/watch?v=pK3YqXD8jGY

Hi Trevor, sorry for the delay in replying. The Mills 1.3 tank was printed in translucent PLA. I'm not sure how ABS fairs but PLA, even at 100% fill, isn't water tight (or fuel tight). PLA doesn't seem to be affected by diesel fuel (glow fuel does affect it) so I rinsed the inside out with Plastic weld solvent, poured in in, swilled it round and poured it out and left to dry and it's now fuel tight.

Just back on here. Definitely the revolve tool is the way to go. The tank on my Mill 1.3 was designed the same way.

hi Ian What I was wanting was to have the first post with all the guides on it and add to it as and when I completed them but it doesn't seem to work like that. When I realised I'd made a couple of simple mistakes and corrected them and resaved the file the link then goes dead. So you need to look for my last post about the guides, currently on the end of page 1, and all the guides are there. What I should have done is have a link to a folder on Google Drive and I could have done what I was wanting. Hope this helps Bob

A tank for an India Mills 1.3cc engine. The tank was printed in translucent PLA and tank top in silver grey PLA. I've been testing PLA to see how proof it is with fuel. I cut a few length of PLA filament and dropped them in jam jars or Diesel fuel and Glow fuel (standard Diesel and Synthetic 10% nitro Glow). Left them for a month of so and the diesel doesn't seem to have had any affect on the PLA. The PLA softened slightly in the glow fuel but didn't dissolve and didn't seem to get any softer than after its first day in it. The print was porous slightly and the inside has been sealed with Plastic Weld solvent. The files for the tank and top are on Thingiverse if anyone wants them.

Sanding sticks, a bit more involved but again available on the Thingiverse download page if you want to give them a go.

A switch cover plate. A simple print but useful for colour matching with your model. Available to download on the Thingiverse page if you want it.   Edited By BobW on 20/04/2017 13:27:38

Very nice What plastic did you use for the wheel and what have you laced it with?

Hi, I've done dummy cylinders in two ways. I decided to do some for my Flair Baronette triplane, I reckoned I could get 3 dangling below the part cowl so made them as you thought by drawing out the full cylinder and splitting it vertically, printing two halves and gluing them together, also added the valve gear on the top along with the weirdly curved inlet manifold (a pig to draw). I got 3 all made then spent half a day kicking myself as I couldn't fit them cos the engine silencer was in the way!!! Ah well. Also done it the other way by printing individual fin disks and stacking them on top of the other engine parts and each other, a much better result. See my pic of the Mills 0.75 electric in the Show us your 3d prints thread. But yes a dummy cylinders might also be another good project.
