Mossys 3D Models

Thanks for all that Paul, yes your right the front is slightly curved, another thing to look at. I have the boiler printing at the moment, but that like the body is really a test to find errors on my part and to get some idea of optimal printing. I am going to concentrate on the chassis as if it won't run smoothly there's little point having a fancy top dressing is there.

 

Finally all 3 major components have been printed, almost a week of work
Chassis Run 1 9hr failed
Body Run 1 11 hrs catastrophic failure
Chassis run 2 with the chassis inverted successful (sort of)
Body Run 2 again with the body re aligned successful (sort of)
Boiler run 1 7hrs successful (sort of)

47 hours of printing over 4 days. The chassis and boiler have minor problems, all easily corrected, the body more fundamental problems with the print and again minor niggles,
all of which was not unexpected, it's the first time I have drawn and tried printing a loco body and chassis. With the 3 bodies pushed together a lookie likee Clas A loco



The next task is to test build the chassis and all it components. It's been drawn with a rigid chassis, but could easily converted to sprung horns blocks if required, also after discussions and advice from Rob P, it has proper radial trucks front and back (a new one on me). Cleaning the radial mountings has been frustrating but once clean the truck move quite nicely but worrying the trucks with open top and bottom are very flexible so I may well print new ones with closed top and bottom.

Initial fiddling with the brake gear looks promising, 1 minor blooper with needs the hangers reprinting but that's about all. Most of which is for next week as we are going to a 3 day Indian wedding with over 500 guests (another new experience), I'm told the parents house is valued at over 2 million with 5 acres of grounds and boasts a large outdoor heated swimming pool, so my mates son seems to have done rather well for himself!

 

It may look the biz but there are lots of bits that need tweeking, there a world of difference between drawing the thing and seeing it in resin. The worst problems are the distortion of the drag beam, (probably a lack of moral support) and which I haven't even looked at is that the smokebox door is at least 1 and more likely 2mm undersized, how, who knows lost in the mists of time.

I will defer to any answer Paul comes up with but I would have thought better to leave them open resin is quite light were as with open space there is somewhere to put additional weight. Would printing them separately cause a problem, 11 hours is a long time to wait and find out, I will stick with them as they are.

 

Cheers Paul,

Yes they are nice looking beasts this one is modelled as originally designed by TW Worsdell (built without coal rails) If you can find a colour photo of one in it's original livery - wow! Saxony green panels, black and white linings and the outside a rich maroon colour, polished brass Ramsbottom cover, brass polished ring between the smoke box and boiler and lots of other fittings either polished brass and or copper. Just beautiful, but way beyond my painting skills.

Sorry should have said my TVB bands have arrived I am just setting one up now and hope for a quick test before leaving for Brum tomorrow morning.

 

Paul,

Your right I could print the body and boiler as a single unit, but I drew the fitting for the retaining bolt on the smoke box, so printed as one would block it. Having said that both can and will be printed as a single print run, that's already been checked saving the 7 hours. As for the chassis, it will be ASB like not Craftsman so need to be printed on its on. And yes the void behind the side tanks is ear marked for any additional weight needed exactly because it's directly over the wheels.

Paul,

The boiler feels very smooth so I guess no vac traps needed, equally the chassis is fine, but there is a district ridge on the side tanks extending all around the body. That needs investigating. In the mean time the only thing I have manged to get done is the number plate. I found an excellent diagram in one of Ken Hoole's books, down to heights of font down to 5 5/8", 3/4" etc, BUT no font details, of course it could be a company specific one. so for the moment I have just used a generic not very lookie likee.

 

Paul/Andy,

I agree using word to locate the best fit is the way to go, I just haven't had the time to do so, also since I have over 200 true type fonts installed, curtesy of loading Pageplus to edit the 2 books I have had published it going to be a long and tedious task even assuming 2/3 of them are instant rejections.

Tom I like the 2 enlargements but interestingly visually they don't fully match up to the diagram in History of NER loco on page 211of Ken Hooles book. He quotes 3/4" for the lettering which I calculated to be .43mm (but I am crap at maths) and 5 5/8" for the number, I have rounded that down to 5 1/2" and calculated it as 3.2mm. So why did I specify .6 and 2.75 on the drawing? Anyway those are fixed looks better but still not quite right. I have also fixed the mounting to match both Ken Hoole and the scans. Just a suitable font to locate. I think the rails that the text wraps around needs adjusting to get closer to the plate rim, that's for another day.

It amazing isn't it taking so much trouble over something which will be almost invisible and as Andy says will have primer, base and top coats sprayed over the top, but it's still good to do, I must be stark raving ^&**(((.

 

Thanks Paul,

I think I got a dose of detail contagion from Rob Pulham and just can't seem to shake it off.

 

Collar and Cuff don't match.

I'm not talking about dyed hair v au natural, but body and chassis. Parking the number plate for a few days I have finally made a start on making up the chassis. It fits perfectly when married up to the body, but, temporarily fit the wheels to chassis and they no longer marry up. The rear wheel cut-outs of the cab floor are to small for the wheels, which also means the potentially the cab internal side bodies will also be to small. I tried figuring it all out in Fusion but in the end gave up and chopped up a copy of the body to produce a test bed.



The rear splasher cut-outs are over sized but when fitted to the wheeled chassis I can get proper measurements and set about adjusting the full body and probably (but hopefully not the cab interior splashers). It's printing now so I should have time to see what's going on later today, not a happy bunny but such is life!
