David Bigcheeseplant Posted August 20, 2015 Share Posted August 20, 2015 (edited) Can any one point me in the direction of a Manning Wardle 3ft wheel drawing or has a close up photos? The Gibson wheels have a 1/8" axle and the tyre looks very thick, giving a very chucky look. I have some Exactoscale P4 3" wagon wheel tyres and thought of 3D printing the wheel centres with a 2mm axle to get that delicate wheel look.

peter220950 Posted August 20, 2015 Share Posted August 20, 2015 Not sure if this is any help, MW 2025/1923 Class L 3' 01/2" wheels? Peter Link to post Share on other sites More sharing options...
AMJ Posted August 20, 2015 Share Posted August 20, 2015 Here is one of the wheels on Sir B sorry it's black with black frames. Earlier MW wheel style or it should be classed as an EB Wilson style but I have seen similar on early Hunslet locos as well. Link to post Share on other sites More sharing options...
David Bigcheeseplant Posted August 20, 2015 Author Share Posted August 20, 2015 It's the earlier style I was looking for, what is the crank throw, as I can draw something up from that. Link to post Share on other sites More sharing options...
AMJ Posted August 20, 2015 Share Posted August 20, 2015 This is a 3 foot diameter wheel which is standard for a MW L class 0-6-0ST. Without taking a tape measure to Sir B as the photo above is fairly square on I think it could be feasible to size from that. Link to post Share on other sites More sharing options...

45609 Posted August 21, 2015 Share Posted August 21, 2015 My wheel so far now to 3D print Looks nice David. Just a couple of thoughts for you. I'm not sure if the Exactoscale tyres you are proposing to use have a counterbore and shoulder to put the centre into but Is the rim radial section thick enough? I know you wouldn't want to add any material to the inner diameter as you will lose the delicacy of the prototype but what about a small allowance on the O/D that could be trimmed/machined off when fitting the tyre. Also why not add the tyre retaining bolt head detail? Cheers....Morgan 1 Link to post Share on other sites More sharing options...
David Bigcheeseplant Posted August 21, 2015 Author Share Posted August 21, 2015 The Exactoscale tyres have a groove on the inside rim. I am not too sure how thin I can make the rim of the wheel centres does anyone know how thin you can print? I will also add the tyre retaining bolts although there is only so much I could do in my half hour lunch break. Above is wheels with tyres and axle.

David Bigcheeseplant Posted August 24, 2015 Author Share Posted August 24, 2015 Wheels now with hex head fixing bolts. looking at the Exactoscale tyre there is a shoulder which the centres sit in so I have amended my wheel centres. I have asked Alan at MODELU if he can print it which he can, so hopefully maybe on the way to a better looking Manning Wardle wheel, the Gibson wheel has eight spokes while mine has the correct ten spokes for the K class.

David Bigcheeseplant Posted August 27, 2015 Author Share Posted August 27, 2015 (edited) First print of the wheel centres, some sight adjustments to the diameter needed but looking good. These wheels are very small. Thanks to Alan at Modelu for doing these really helpful and will be at Scalefourum in September.

Thanks to Alan at Modelu for doing these really helpful and will be at Scalefourum in September. That looks very convincing. Will these be released to the public generally?

David Bigcheeseplant Posted August 28, 2015 Author Share Posted August 28, 2015 I don't really plan to sell them to the wider public but if anyone is interested I may have a few spares, just PM me. They will fit the Exactoscale tyres so P4 only Link to post Share on other sites More sharing options...

davknigh Posted August 11, 2016 Share Posted August 11, 2016 No sign of any change should there be? I was just wondering how they held up to being put on an axle as compared to, say, a Gibson wheel. Yours have the advantage of the right number of spokes. Cheers, David Link to post Share on other sites More sharing options...
Killian keane Posted July 26, 2017 Share Posted July 26, 2017 I wonder if there would be interest in doing Hackworths plug wheels in the same manner? I would certainly be interested Link to post Share on other sites More sharing options...
