mikeandnel Posted August 11, 2013 Share Posted August 11, 2013 I would be very grateful for any advice or guidance on how to re-gauge a Bachmann 0-6-0 loco chassis from '00' gauge to 'EM' gauge please. as I have never done this before. I normally build my own chassis but I have come across a Bachmann loco that I can use if it can be re-gauged. Many thanks Mikeandnel Link to post Share on other sites More sharing options...
garethashenden Posted August 13, 2013 Share Posted August 13, 2013 Which chassis is it? There are two main routes to EM, either replace the wheels or pull them partly off the axles. Ultrascale may have replacement sets, those would be easy to install, just remove the old ones and put in the new ones. But they're expensive and take months to arrive as they are made to order. You could also look at Alan Gibson, they do a lot of replacement wheel sets on the correct diameter axles, but they require quartering. The third method is to simply use what's there and pull the wheels apart a bit. It may work, I've seen it done successfully, but the axles may be too short and if it's an older chassis the flanges may be too big. Link to post Share on other sites More sharing options...
mikeandnel Posted August 13, 2013 Author Share Posted August 13, 2013 Hello Gareth I was beginning to think that no-one was going to reply so thanks for your input. I have always either kit or scratch built my locos but Bachmann are soon to bring out an LBSCR E4 class loco and as I am getting older and the quality of R-T-R models is improving, I thought I would order one and re-gauge it. So any advice on how this could be done is more than welcome Michael Link to post Share on other sites More sharing options...
robert17649 Posted August 13, 2013 Share Posted August 13, 2013 if its any help I have regauged a Bachmann Jinty chassis simply by easing the wheels out to the correct btB for EM gaugeI have done the same with a Hornby Lord of the isles and a T9 care needed adjusting the pick ups however and the whole thing should be done slowly and carefully, with older chassis I doubt its that straightforward as flanges are huge on older models.i am about to do the same to a Hornby M7,although for the prototype i'm after I may change the wheels using Markits rP25' profile wheels( different diameter needed) . I seriously doubt that the same thing can be done with split collection chassis. i any case the moulded brake gear needs trimming thinning or even replacing. I waited ages for an ultrascale drop in set for a pug,brilliant when they arrived! good luck robert Link to post Share on other sites More sharing options...
garethashenden Posted August 13, 2013 Share Posted August 13, 2013 As the model hasn't been released there aren't any replacement wheelsets available yet. I'd be tempted to buy it and try pulling the wheels out to the correct spacing. If that doesn't work then you can try something else afterwards.

mikeandnel Posted August 13, 2013 Author Share Posted August 13, 2013 For Robert and Gareth Thanks for the advice but what tool would you recommend for pulling the wheels further out on their axles? Michael Link to post Share on other sites More sharing options...
garethashenden Posted August 13, 2013 Share Posted August 13, 2013 A wheel puller is the tool you want. NWSL make good ones, not sure how available they are in the UK though. The problem is finding one small and delicate enough. They are commonly used in the automotive world for removing bearings and such. GW make one as well.

mikeandnel Posted August 16, 2013 Author Share Posted August 16, 2013 Gareth Thanks for the tips. The GW puller seems to be the most readily available, but I am going to try the twisted screwdriver method first when I get the loco, even if just to save money. As you know this loco may be a one-off as I normally build my own Regards Michael Link to post Share on other sites More sharing options...
MikeOxon Posted August 17, 2013 Share Posted August 17, 2013 Instead of a puller, I widen the gauge by tapping in the axle using a suitable drift (e.g. smaller diameter axle) The wheel is supported on a slotted plate, in my case resting across the jaws of my bench vice. Then I use a light hammer to tap in the axle, checking the back to back as I go Link to post Share on other sites More sharing options...
mikeandnel Posted August 17, 2013 Author Share Posted August 17, 2013 Mike Many thanks. Your suggestion is perhaps a better way to try re-gauging providing my arm is not in sledgehammer mode!. As I have never done this before, am I to understand that Bachmann wheels are fitted on splined axles? Best regards Michael Link to post Share on other sites More sharing options...
robert17649 Posted August 29, 2013 Share Posted August 29, 2013 For Robert and Gareth Thanks for the advice but what tool would you recommend for pulling the wheels further out on their axles? Michael I basically use the same method as Mike but put the wheel on my vice wit the axle just touching the faces on each side. then drift as Mike. Final stage is to press the wheels in with a Btb gauge in the way.. This does need the wheelsets removed from the chassis Link to post Share on other sites More sharing options...
