David Thanks David. I was thinking of massacring a couple of sets of Exactoscale wagons wheels. This might sound like a dumb question, but if going down the Ultrascale route, I just need to measure the overall diameter and width of the rim. No funky math to make sure its a interference fit or anything? J Link to post Share on other sites More sharing options...

J I sent the tyres to Alan Butler at Modelu so I think he may have adjusted my original design slightly to fit the tyre, so I cant tell you want the inside diameter of the tyre should be, also the Exactoscale tyres are less than 2mm and the wheels where designed to match, so probably best to get a micrometer out and check.

49395 Posted June 24, 2020 Share Posted June 24, 2020 Apologies if this has already been asked, having recently taken delivery of a Hattons 14” Barclay I was wondering if wheels for one of these might be possible with a view to P4 conversion? Many thanks Mike Link to post Share on other sites More sharing options...
David Bigcheeseplant Posted July 24, 2020 Author Share Posted July 24, 2020 I have been playing with my wheel generator and printed centres off for the 3' Peckett and Barclay wheels in P4 They push nice and tight in to a Gibson tyre and on a 1/8" axle. I had to create a variant of my programme to design the square spoke rather than oval on the previous designs. David 2 4 Link to post Share on other sites More sharing options...
davknigh Posted July 24, 2020 Share Posted July 24, 2020 (edited) Those look very good David . I suspect I am not alone in wondering when and how they will be made available for purchase as I have need for four axles worth of the Pecketts. Belated addition, in P4 please.

Stanley Melrose Posted July 25, 2020 Share Posted July 25, 2020 I'll order 2 x Pecketts and 1 x Barclay (all P4) whenever you want to start supplying. Stan Link to post Share on other sites More sharing options...
David Bigcheeseplant Posted July 25, 2020 Author Share Posted July 25, 2020 I am going to get some people to do some test builds on these wheels first as want to ensure others are happy with the way they work etc. Also currently these inserts fit a standard Gibson P4 3'1" wagon wheel tyre. The prototype Barclay wheel is pretty close to this although the Peckett maybe an inch or two out has any one got the exact dimensions for this wheel as I may do a version that fits the wagon wheel or another one that is spot on. I need to cost these up but at the moment I am looking around the £6 for four wheel centres. David 1 1 Link to post Share on other sites More sharing options...

I know it's bad practice to measure the model as a datum but as I've used the Hornby wheel centre to fit a slightly thinned Gibson P4 tyre.

Middlepeak Posted July 25, 2020 Share Posted July 25, 2020 David, If you're pondering over tyres, I have used Ultrascale tyres on my Peckett, fitted to turned down Hornby wheel centres. Worth investigating, as the range he can produce is quite varied and I found delivery times not too long (about a month).

David Bigcheeseplant Posted July 26, 2020 Author Share Posted July 26, 2020 This is the Peckett wheel with a 3'2" tyre, I can make these centres for Ultrascale tyres athougth there is not a lip at the front of the tyre for the centre to locate up to. Although this would give a finer edge to the tyre. David 1 Link to post Share on other sites More sharing options...
David Bigcheeseplant Posted August 5, 2020 Author Share Posted August 5, 2020 Mike Trice has printed some wheels centres off in a harder machinable resin, Also the 9F wheels he has popped a Romford style axle fixing although I can do this or a standard 1/8" 3mm or what ever size plain axle is required.

Gordon A Hi Gordon, Can I ask please; do these wheels run true? Did you machine the edge of the printed wheels before fitting the steel rims? They are really impressive and I'm hoping at some point that you will allow me to exploit all your hard work so that I can fit the correct profile wheels to the LNER loco's that I am scratch building (sort of) for Clayton.
