All pointwork terminology reads from the toe of a turnout (the blade tips) towards the heel of the turnout (where the roads diverge). cheers, Martin.

RMweb Gold martin_wynne Posted December 13, 2020 RMweb Gold Share Posted December 13, 2020 One reason for removing the infill at the far end, is that your only competitor (based in America) inserts a ludicrous infill there which makes it look like a cast bullhead crossing, which are extremely rare. So you can make a point of no infill as a product feature in your advertising. cheers, Martin. Link to post Share on other sites More sharing options...
Wayne Kinney Posted December 13, 2020 Share Posted December 13, 2020 Thanks Martin, I added the infill for strength and cast-ability. I believe I can reduce this and still have it cast fine, as the other end is unsupported anyway. 2 Link to post Share on other sites More sharing options...
Chuffer Davies Posted December 13, 2020 Share Posted December 13, 2020 Hi Wayne, thanks for the pictures of the vacuum formed moulds - fascinating! Would I be correct in thinking that the sleeper bases have to be injection moulded, in which case you have a lot of moulds to engineer? Are the moulds made using traditional methods or is there a new way of doing this these days? Frank Link to post Share on other sites More sharing options...

Frank Thanks Frank, The bases are manufactured from a specially researched mix of resins and colour pigments using a high quality professional 3D printer (which was a large investment). It took me 4 months to perfect the resin mix, working with 3 different resin companies. Also, finding the right machine was very difficult. The advantages of this approach, compared to injection moulding, are: Manufacture of a HUGE variety of formations not financially possible with IM. Fast 'prototyping' and revisions. Opens the possibility of offering different standards (00 'Standard', 00-SF, EM), again not financially possible with IM. Possibility of making 2/4 bolt chaired versions as 'custom' orders, rather easily. Inclusion of more specialty chairs as per the prototype. To go from idea, CAD and final product in weeks rather than months. More intuitive to tweak the design, test and make improvements (for example, rail fit to chairs). So the final material for the base is a mix of 3 different specialty resins to attain the desired properties.

I just couldn't imagine how you were going to prepare so many IM's. A year or so ago Colin Ashby gave our local area group of the EMGS a tour of his manufacturing facility and demonstrated the process of creating injection moulds. In the past Colin had been responsible for creating the moulds for many of the small kit suppliers of wagons and coaches. I just couldn't imagine how you could turn around so many traditional moulds in such a short space of time. I really must invetigate this 3D printing malarkey in more detail. It has come on in leaps and bounds in the last couple of years. Thank you for taking the time to explain this in so much detail, I really appreciate it.

This is a marvelous product, mostly because it bypasses the traditional high tooling costs and design inflexibility of injection moulding to allow for a very wide range of items. But as that manufacturing technology can be purchased, I would think that PECO and soon after, Bachmann, are going to be major competitors, and very quickly. Or it will be another case like Facebook vs. Instagram. Tim 1 Link to post Share on other sites More sharing options...
Michael Hodgson Posted December 14, 2020 Share Posted December 14, 2020 One of the reasons some modellers build their own track is because they want to run mixed gauge - I couldn't help wondering whether that might be less difficult a proposition if the bits for these points are made available separately for those who want to do that sort of thing. It's not something I would ever want to do and obviously it's a very small niche market. 1 Link to post Share on other sites More sharing options...

RMweb Gold tomparryharry Posted December 14, 2020 RMweb Gold Share Posted December 14, 2020 It looks very, very interesting. Peco bullhead is alright, but the confines of a limited range mean that it's difficult to get away from 'train set' geometry. Nice.

robmanchester Posted December 14, 2020 Share Posted December 14, 2020 Hi Wayne, I was expecting some high-tech workshop facility but to see the vacuum machine in the lounge with the wedding photo(?) in the background was quite a shock Shooting too early isn't usually a problem - gives time for getting your feet up and a cigar...... Off now to solder up some crossing vees. Keep the thread rolling and well done. Rob 1 Link to post Share on other sites More sharing options...
