Wbnemo1 Posted July 25, 2007 Author Share Posted July 25, 2007 Posted: Tue Jul 24, 2007 10:48 pm Post subject: -------------------------------------------------------------------------------- Howdy gang, I just wanted to update everyone interested. I had a chance to do a little on the Firefox. I started laying the sheet wax into the bottom half of the mold. Now, perhaps the method I'm employing makes a little more sense. there are a few gaps you will note and these get smoothed over using clean clay. Also, I didnt go all the way up to the edge. Again this gets finished with clean clay to ensure the proper edge. see the pics, as always, questions welcome. Once I get the clay into the gaps and smooth everything over, pour sprue and vents applied, a liberal amount of mold release will be applied, then final rtv rubber poured. this will complete the bottom half of this stage one mold, then this process is repeated on to the top half. Enjoy the pics. Sincerely, Will Link to comment Share on other sites More sharing options...
Wbnemo1 Posted August 1, 2007 Author Share Posted August 1, 2007 ok, I clayed up the wax in the bottom mold last night. Now I just need to add vents and pour sprue and she's ready to pour last half..as for the sheet wax, you can get quite a few different thickness(in thousandths), adhesive backed or not. note for those interested, the adhesive backed is a little more pliable, I chose .100 thickness. I think that will be thin enough, but still have strength once resin is poured in the cavity created by the sheet wax.

Wbnemo1 Posted August 20, 2007 Author Share Posted August 20, 2007 Howdy, just a quick update, I finally engineered how to finish this mold process and will be showing new pics shortly. stay tuned... Sincerely, Will Link to comment Share on other sites More sharing options...
LSP_Matt Posted August 21, 2007 Share Posted August 21, 2007 Very interesting. Great pics. Will stay tuned for more as I'm very curious about the hollow casting process. It looks very laborious. Thanks Matty Link to comment Share on other sites More sharing options...
Wbnemo1 Posted September 4, 2007 Author Share Posted September 4, 2007 tiny update, I had time to work on the patterns for the landing gear doors. they are as accurate as I can get em based on my reference and look pretty darn nice if ya ask me...pics soon Will Link to comment Share on other sites More sharing options...
Wbnemo1 Posted September 4, 2007 Author Share Posted September 4, 2007 Here's a pic... This is what they look like so far. There is still some detail to add to them before remold. Will Link to comment Share on other sites More sharing options...
Wbnemo1 Posted October 9, 2007 Author Share Posted October 9, 2007 Update!, Ok, as promised here we go..I'm quite happy with the final result of this casting so it will become the lower fuselage for the new "hollow"master pattern. The inside will be super smoothed out like an injection kit for final molding process. This series of links, in order, will hopefully give everyone an idea as to the casting and demolding process. I couldn't pour this casting under pressure and due to that fact ther are a couple airbubbles. the most prominant one is on the starboard side intake on the inside. There is also one on the front of the belly intake edge as well as the side of the belly intake, both about the diameter of a No2 pencil lead. on to the pics..enjoy Best, will Link to comment Share on other sites More sharing options...

Steve C Posted October 10, 2007 Share Posted October 10, 2007 Couple of questions about the mold. How long (how many parts) will the molds last? Do the masters have panel lines and if so how well do those lines transfer to the cast parts? Thanks, Steve Link to comment Share on other sites More sharing options...
Tsrjoe Posted January 19, 2010 Share Posted January 19, 2010 a beautiful piece of mould engineering there Mr.B, definately looking forward to seeing how shes progressed best wishes, Joe Link to comment Share on other sites More sharing options...

Wbnemo1 Posted January 19, 2010 Author Share Posted January 19, 2010 Howdy, Boy... it's been a while since I've visited here.. I had a tragedy take place in my life that stopped the project for a time. First my Dad had passed due to a heart attack, then same year in November, my son was stabbed through the eyes with a military dagger. He's ok now , but due to stabbing lost left eye and very minimal in the right leaving him legally blind now. What makes it more horriffic is that is was my sister that assaulted him. No more details on that, it's pretty much all available online anyway. So recently I've gotten back to work on the project, started waxing up the top half for the final premold... I'll show pics tonight. Joe send me an email please... Cheers, Will Link to comment Share on other sites More sharing options...

Glad to see that things are getting better and the build is back on. Kev Link to comment Share on other sites More sharing options...
