David Holman Posted February 11, 2016 Share Posted February 11, 2016 Good for you, am sure you will get much more satisfaction from making something yourself than just opening a box - even though many boxes have very nice contents these days!

brianmcs Posted February 13, 2016 Author Share Posted February 13, 2016 Hi Guys , thanks for all the encouraging comments , especially Scahalane whose own excellent build of these was part of the inspiration for me to have a go. The ends were made by casting some machinable wax into a mould and machining them to size on a small lathe . I am working from the drawing on the forum and the photos on the net. These are very good but not great for the smaller detail such as the hatch lids , so if anyone can offer more detailed pics I would be very grateful .

brianmcs Posted April 11, 2016 Author Share Posted April 11, 2016 HI Guys , the day job has slowed progress on this , but I got the mould made . This is the first "pull" from it . It is in a polyurethane resin . The white one is the master . I need to work on eliminating the air bubbles in the resin . Quote Link to comment Share on other sites More sharing options...
Mayner Posted April 11, 2016 Share Posted April 11, 2016 Very impressive. Did you use a one or two part mould? Quote Link to comment Share on other sites More sharing options...

brianmcs Posted April 12, 2016 Author Share Posted April 12, 2016 thanks guys , the mould has one part in silicone rubber and a core made in acetal both of which are inside an acetal box or " shell" . not sure if that makes it a 2 or 3 part mould? Now that I am starting work on the chassis does anyone have any advice re which bogies to use ? Quote Link to comment Share on other sites More sharing options...
murrayec Posted April 12, 2016 Share Posted April 12, 2016 Hi brianmcs The mould looks cool, though it looks like you had an air problem also! the silicone looks like it needs to be evacuated when mixed and before pouring to make the mould- this may help in casting bubble free casts. Also you could try a mould spray loubricator it may stop the plastic cast forming bubbles at the bubbles in the mould! if that makes sence? SSM do the bogies sides your looking for or you could the Y25 bogies from Bachmann which are a bit smaller then Irish ones Eoin Quote Link to comment Share on other sites More sharing options...
Dunluce Castle Posted April 12, 2016 Share Posted April 12, 2016 Very, very nice casting. Reminds me I must try it out some time soon. Quote Link to comment Share on other sites More sharing options...

SSM do the bogies sides your looking for or you could the Y25 bogies from Bachmann which are a bit smaller then Irish ones Eoin Hello Eoin , I am a big fan of your work . There are air bubbles in the surface which you can see but virtually none on the surfaces of the part. This can be achieved by brushing a coat of the silicone onto the part first . If I was doing this professionally I might invest in some vacuum equipment which would produce a better result . I am using a spray on wax on the silicone and a honey wax on the acetal core ( in the day job I work with GRP ) The lubricant will not usually eliminate the air bubbles in the polyurethane resin but there are a couple of ways of doing this . I will try them and post an update . Thanks for the tip regarding the bogies . Brian. Quote Link to comment Share on other sites More sharing options...
murrayec Posted April 12, 2016 Share Posted April 12, 2016 (edited) Hi Brian Thanks I'm now a fan of your work, when I saw the way you put the mould together I said 'he's done this before' - GRP - I did a bit of that years ago working on boats n stuff- a long time ago!! Even the master model for the mould is very neat Eoin Edited April 12, 2016 by murrayec Quote Link to comment Share on other sites More sharing options...
