Ranger Posted August 21, 2019 Author Share Posted August 21, 2019 There is no mold as such 6Stelab9. It would probably be easier if there was but I like sand casting but it’s slow, well until you have done it a few times then you can speed up a bit. I am in no rush though and if you try and rush it then your increasing the chance of a failed cast. You just use or make a master and reproduce it in sand. I will make another tomorrow, it comes out (hopefully) just like the one shown here. I cast up hands in metal the same way for the big foki I made about. 3 years ago. It has its limitations as to what you can reproduce though. When it works it’s rewarding! Large Foki hands I cast up below. I made one in wood first.

RoboDerby Posted August 22, 2019 Share Posted August 22, 2019 In case it needs to be said, I too would love to be on a list if such a thing comes to pass. The hand looks great Paul. It all looks great! Link to comment Share on other sites More sharing options...

robothut Posted August 22, 2019 Share Posted August 22, 2019 Some guys that cast metal parts are using 3d printed plastic parts as the master that they burn out of the sand mold, There vids on you tube any way. That way they can make a master part that is the same every time when making the sand mold. Link to comment Share on other sites More sharing options...
Ranger Posted August 22, 2019 Author Share Posted August 22, 2019 Yes John, as long as the part is strong that’s a good way to do it. I can use my masters or whatever I find to use as one over and over until they get worn out. That’s when the printer would be a real time saver as you could print as many as you want. I don’t have a 3D printer to try it yet. Not something I am really bothered about getting even though the things you and Brian make with them are truly amazing. I will leave that to you guys, you have 3D printing nailed for sure. Dunno, maybe I may venture into 3D printing one day but my stuff is a lot more basic so I don’t feel the need to get one. I am happier with a pencil and paper and a few hand tools etc than sitting at a computer. Hmm, I suppose I might be able get Brian to print plastic parts for me to cast and I could cast metal parts for him. . Link to comment Share on other sites More sharing options...
Ranger Posted August 31, 2019 Author Share Posted August 31, 2019 Ok, my daughter is safely back in Australia now so it’s on with the foki today. Need some small brass screws for the ears. That or just paint the heads copper/gold. It’s all just balanced loosely together at the moment. I just need to fit the feet to the legs, the legs to the body. Then cast another hand and fit them, put on the brass face surround, fit some lights etc, a bit of tweaking and it should be done. As I have said ,this one is just a rough version to see how it might look. For a small robot, it’s heavy! Link to comment Share on other sites More sharing options...
RoboDerby Posted August 31, 2019 Share Posted August 31, 2019 This is simply marvelous Paul! I love it! Link to comment Share on other sites More sharing options...
Ranger Posted August 31, 2019 Author Share Posted August 31, 2019 It’s got a few errors but it’s a learning curve. I have since thought of better ways to do a few aspects of it. It will look ok for a first attempt at this scale. It’s been harder to do than the big one really. Link to comment Share on other sites More sharing options...
Golddalek Posted September 1, 2019 Share Posted September 1, 2019 Very shiny and impressive. I like the different blends of metals. Link to comment Share on other sites More sharing options...
Ranger Posted September 1, 2019 Author Share Posted September 1, 2019 Foki with ‘Death Ray’ Its as good as it’s going to get for now. Not at all perfect but I can see how it looks and what needs changing etc. Could do with some small brass fitting for the ears but I haven’t any at the moment. Feet could be bigger and he could also be a tad taller. I will post a short video, when I figure out how to do it! Link to comment Share on other sites More sharing options...

RoboDerby Posted September 1, 2019 Share Posted September 1, 2019 Yes!!! Very cool Paul! Looks fantastic and very cool lighting effect. Wow! Seeing the Foki next to the Astro Spaceman really puts the size in perspective. Must be a real challenge working in that scale. Well done! Link to comment Share on other sites More sharing options...
