MrWolf Posted July 5 Share Posted July 5 There's always a way around these things: Obtain measurements of popular 7mm scale wheels and bearings as appropriate to the model. Design the inside of the axle boxes to suit. Create rest of model with your usual aircraft quality engineering. Offer kit sans wheels, recommending the type, Slaters for instance that you worked from, or offer to supply inclusive at £X. I suspect that if you have the space and money for an O scale layout with the type of detail you can offer even in 4mm, buying a set of wheels is already factored into the hobby budget or is possibly insignificant. A safe way forward would be to share the pictures of the CC7 with the 7mm areas of the site, plus the scratch/ kit building threads and asking if anyone would be interested in a scaled up version? Apologies if I'm stating the obvious. Also, rest in peace Donald Sutherland. Hope you're drinking wine, eating cheese and catching some rays whilst Moriarty fixes the busted tank. 6 Link to post Share on other sites More sharing options...

Thank you for explaining. As elsewhere in life, if you know, you know. But if you don't, it's nice to be told. I would have calculated approximately by working out the volume of three cylinders (two wheels + axle). But would need to know the wheel and axle diameters to achieve that. 1 1 Link to post Share on other sites More sharing options...

When I did my O gauge GWR N6 Coal Wagon I designed it to use Parkside wheels & bearings (621/627) and buffers, 3-link coupling & drawhook (622/623), which as you say adds at least £20+pp to the cost. Parkside was the easy option as they’re easily obtainable from many model shops, and I’ve no experience of any others. They appear to be more than adequate for the job. Then add transfers, another £5+. But in O gauge a standard Dapol van is typically £47 at discounted prices. I’d be interested in an O gauge CC2 if you decide to proceed. 2 Link to post Share on other sites More sharing options...

I’ve recently purchased a Peco O gauge wagon kit to use as a guide for dimensions (buffer height etc) so it is something I’m seriously looking at although I would probably supply the ‘kit’ without any hardware such as wheels/bearings/sprung buffers etc However the first one will be fully built as a test run so I might possibly consider selling the prototype…maybe? 7 Link to post Share on other sites More sharing options...
RMweb Gold Popular Post chuffinghell Posted August 3 Author RMweb Gold Popular Post Share Posted August 3 (edited) As mentioned previously I have been thinking of resurrecting an abandoned project, namely an attempt to recreate this The main reason for resurrecting this project is due to buying an Andrew Barclay from a well known auctioning site that arrived with damage to the cab So instead of returning it I destroyed dismantled it and stripped off the paint I had the cab printed by shapeways a well know ‘digital manufacturing platform based in the Netherlands’ well before I had my own printer (and before their prices became ridiculous) As with all my projects I don’t expect to make any rapid progress And yes I am aware the the 701 in the first photo is an incorrect reproduction of the actual 701 but I like it and fancied modelling it Edited August 4 by chuffinghell 21 3 2 Link to post Share on other sites More sharing options...

RMweb Gold chuffinghell Posted August 4 Author RMweb Gold Share Posted August 4 (edited) Well I’ve gotten further than I did last time I tried to model 701 The chassis is in primer 😮 Had to use an etch primer unfortunately* because the only other I’ve got is plastic primer from that well known automotive shop (the one that fits windscreen wiper blades for people that are incapable of basic car maintenance) *It’s thicker than I would have liked but certainly not as thick as the paint that was already on it from the well know model railway supplier that sadly closed I also found some H****y dummy screw link couplings in my bits box so I’ve opened up the hole in bufferbeam and repainted the couplings I appreciate it seems daft removing black paint to repaint it black but as previously mentioned the thickness of the paint was shocking and it was also too glossy….plus it was chipped in places and there is no way I could have touched it up successfully Edited August 4 by chuffinghell 12 Link to post Share on other sites More sharing options...
RMweb Gold chuffinghell Posted August 4 Author RMweb Gold Share Posted August 4 Having looked at the cab I’ve decided that I’m going to attempt to print a better one with more detail After applying primer I noticed a lot of surface imperfections that I struggled to correct It was originally drawn using primitive software and the print itself isn’t great I was being lazy thinking I would get away with what I had but I might be able to print one much better. Unfortunately the original drawings have been lost so I will have to redraw it At least it gives me the opportunity to add more details like rivets etc 3 Link to post Share on other sites More sharing options...
RMweb Gold chuffinghell Posted August 4 Author RMweb Gold Share Posted August 4 (edited) I’ve invoked rule one again and replaced the short chimney with a more convincing GWR style from a pannier…. ….how I ended up with a pannier chimney in my bits box I don’t know, waste not want not Don’t care if it’s wrong mainly because its been glued on with solvent now Just need to try to sand away the join Edited August 4 by chuffinghell 9 1 Link to post Share on other sites More sharing options...
RMweb Gold chuffinghell Posted August 4 Author RMweb Gold Share Posted August 4 Put a bit of primer on so I can see where needs sanding or filling, I’ll strip it off once I’ve got it right not perfect and I can still see the join 12 Link to post Share on other sites More sharing options...

RMweb Gold chuffinghell Posted August 5 Author RMweb Gold Share Posted August 5 Filled and sanded it as best as I could, removed the guide coat back to bare plastic and applied an even coat of primer I can still see the join 🙄 but it will do I glued up the handrails while they were on the body then removed them to give them a coat of etch primer in the hope it won’t rub off the brass Handrails glued in place, once I’ve drawn up and printed the cab I’ll give the whole lot another light coat of primer Brass handrail knobs and wire look much better than the plastic handrails it came with….in my opinion of course 11 4 1 Link to post Share on other sites More sharing options...

I used 90% IPA and a soft tooth brush after soaking for an hour to get the Vallejo acrylic paint off it. I suspect you could probably dilute the IPA further (mine was 90% from the bottle) and still get a result, but this was my first and only time I've had to strip a paint job, thankfully, so I've not had a chance to experiment. 2 2 Link to post Share on other sites More sharing options...

I specifically qualified the paint i was stripping as I've not tried it on any other brand or factory finishes, so what works for Vallejo, may not work for other paints. 1 Link to post Share on other sites More sharing options...
