Wheel pullers
|
I have a GW Models wheel press and a GW Models wheel puller. I think my gear puller, for getting worms off motor shafts, may also be GW Models but I've had it so long I can't remember! The wheel press sets plastic centred wheels perfectly at 90 degrees.? If you are modelling a 3 cylinder NG loco (can't think of one offhand) you are stuck but, who can see both sides of a model at once!! When using the wheel puller with plastic centred wheesl remember the advice given years ago in MRJ (and possibly also in the Review) to make a disc to go behind the wheel so the plastic centre isn't distorted as it is pulled.? Its a few moment's work with an Olfa compass cutter but saves the cost of new wheels.....how do I know.......... :-( Adrian |
开云体育Adrian is dead right, don't pull a wheel, particularly a plastic spoked one by the rim. ?My preference is to use a plate with a slot in it, placed behind the wheel, set on an open vice, and tap out the axle. On pin point axles use a brass, copper or aluminium drift to protect the point. ? Worms attached with superglue can be removed with a soldering iron. Apply it to the end of the worm away from the motor. If there's room, keep a pair of pliers on the shaft between worm and motor as a heat sink. Big wattage, big bit, high temperature, absolute minimum dwell time, As soon as worm comes off dab shaft with wet Q tip. So far, I've always got away with it! ? Frank ? From: O14@... [mailto:O14@...]

Hello Adrian and others, Sorry for going off topic, but while I can't help you with a 3 cylinder NG loco, the Tasmanian Government Railways had two 8 cylinder Garratts, provided you're prepared to accept that 3'6" is narrow gauge. They were, I believe, the only 8 cylinder ones ever built. ? Their classification was?the?M class, wheel arrangement?4-4-2 + 2-4-4, with 4 cylinders at each end.? I've never seen a model of one, and I guess it only adds,?with the TGR K class, to Tassie having had some of the weirdest?Garratts built. ?? Regards Ian Johnston |
