  • Okay understood. Only printed out one prop on my fdm machine, and I was pretty pleased with the way it came out. As you iterated it needed a lot of supports, but they trimmed away easily, and the prop needed a light sand anyway to remove the lines you get with fdm printing. No experience with resin printing, are the supports a bit more tricky to remove?

      The resin is quite hard so the supports tent to breakaway when removing them, and that will leave a pit or in the worst case take an edge of your part with them.
      Also, with resin printing if you print a bore that is placed under an angle, you are not ending up with a cylindrical shaped hole, it will be deformed at the top. But once you figured all that out the hard way, it is very enjoyable (except the post-processing, that is a real mess).

      • I see. PLA is quite brittle too, so I tend to trim the supports away with a scalpel, cutters etc. and then clean back any remains with small files, sanding strips etc.

        • Needed to free some space on my workbench, so I decided to tackle the tools for the stern.
          It will be a 3 piece tool.

          First, I casted the inner core of the stern in RTV silicon rubber, this tool will be used to make the stern hollow. You can see that the index ring, for paring the stern to the hull, is integrated in this tool.

          Next up was the tool of the stern master, various cores are inserted, used for: prop shaft bearings, rudder stockís and alinement pins to align the rudders and planes with the rootís that are integrated in the stern.
          It took me a while to get everything properly aligned, you can see the small bushings on the brass rods that I had to order to make it happen.

          Next up will be tool of the other side of the master and then the casting of the stern in resin.

                If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.

                • I could completely retool the back end of the 667 to keep up with Bart, but can anybody? I don't know if I have the energy.....

                    • The fwd grating on the sail was integrated in the print but it didnít turn out as I wanted. Before making the mould I had to address that.

                      Traced the contours of the new part on the sail, contour was cut out and grinded to take the new part.

                      New part was glued in place with CA, applied baking soda to fill up the gaps, air dried putty was used to fill up the small imperfections.

                        • Me too, you Belgian muffin. Some of us have genuine excuses for not posting (and some others come from chocolate making countries)! Get with the program; I'm dying (literaly) to see this thing finished.

                          • Hi Guy's, I'm stil around. I'm busy for "who must me obeyed".

                            Kids outgrow the garden so we desided to turn it into our little paradise.
                            Landscaping the garden is almost finished, new shed, paving and flower boxed (don't know if this is a word).

                            As compensation we agreed that I can move my workshop from the basement to the garage were I have daylight, yes.
                            The content of garage (now acting as a laundry room) has to move to the basement, need to install an additional pump for the washing machine and replace the stairs, the one in now is to steep to be save (I was used to it but it will be to dangerous going up and down with the laundry).

                            So I'm busy on all front except on the sub, I haven't a workshop anymore, beginning of march is my goal to have it ready.

                            Grtz,
                            Bart
