Wyvern Posted November 8, 2011 Share Posted November 8, 2011 Can anyone recommend a wheel puller for use with ultrascale wheels - fohrmann has been suggested would this be appropriate? Also how would you reduce the back to back? advice greatly recieved Cheers Guy Link to post Share on other sites More sharing options...

Also how would you reduce the back to back? advice greatly recieved Cheers Guy I use a fohrmann wheel puller. It works but can be a bit of a knack to use on some wheels - especially on pin-point axles - but there are tricks. To reduce back to back use a wheel press. fohrmann also do one and I believe so does GW. Link to post Share on other sites More sharing options...

craigwelsh Posted November 8, 2011 Share Posted November 8, 2011 Why do you need a wheel puller with Ultrascale wheels, you can normally push fit them on the axle until they are pinned/glued? I normally just push them up against the back to back gauge to set that measurement without needing any tools. Alan Gibson wheels usually need a tool to push them on as supplied as the fit on the axle is much tighter. Link to post Share on other sites More sharing options...

Wyvern Posted November 9, 2011 Author Share Posted November 9, 2011 hi thanks for the contributions so far. Perhaps I should elaborate on what I am trying to achieve. I bought a second hand Bachmann 08 with an ultrascale wheel pack. The quartering had gone so I fixed this and pinned the cranks, it now runs smoothly. I now need to open up the wheel s to the correct p4 back to back of 17.75 and pin them to stop them moving during wheel cleaning . It was my concern that as these were previously glued I risked pulling them out of true when moving them along the axle. Many thanks Guy Link to post Share on other sites More sharing options...
craigwelsh Posted November 10, 2011 Share Posted November 10, 2011 You'd be better off twisting them to break the glue bond first before pulling them out i'd think anyway. The wheels shouldn't matter to the quartered cranks. The GW Models puller should be ok with the cranks in place Link to post Share on other sites More sharing options...

smokebox Posted November 10, 2011 Share Posted November 10, 2011 This is a wheel puller used to fit, adjust and remove wheels from axles Link to post Share on other sites More sharing options...
bertiedog Posted November 10, 2011 Share Posted November 10, 2011 The problem with all wheel pullers and both Gibson and Ultrascale wheels (also older Sharman wheels), is that the rim is not attached to the spokes, except by a force fit. A traditional puller grips at the rim and pulls or pushes, but this can shift the rim on the modern wheels, they are not keyed to the centre like the Hamblings wheels were. So to be safe using the pullers, it is best to cut out a washer in brass or aluminium sheet to fit over the entire back of the wheel to spread the load. This can be a slot fit to go over the axle, and can be as thin as 10 thou brass sheet. But the best advice is not to use pullers or pushers, both makes go on fine with simple hand pressure, or the assistance of a large bench vice, it does not need brute force, just gentle steady pressure from the big jaws. To adjust outwards, then gentle pressure from a lever will work fine, but a firm twist will usually work, don't try to get the back to back right on levering out, take off the axle, and press in again to the correct figure, it is easier. With both makes it is vital to prep the axle end with a chamfer, it does not need a lathe, just put into a power drill and gently chamfer the extreme end with fine Emory paper. Then run a scalpel around the rim on the hole to remove any flash, then they will slide home easily, and can be locked with adhesive if too loose.(or Cross pinned). Stephen.

craigwelsh Posted November 10, 2011 Share Posted November 10, 2011 http://www.fohrmann.com/spezial-werkzeug-fur-modellbahner/mini-wheel-puller-3942.html is more like the GW models one with the variable jaws. I guess you could modify a vice to do a similar thing fitting a pin to push out the axle on one jaw and a slot in the other jaw for the axle to sit in while you close the vice.

Stephen. I was under the impression Ultrascale cast their wheel centres into the tyres? I think Exactoscale are the same. I know Gibson are a push fit hence the issue sometimes with tyres coming out, especially if there was still a moulding pip on the centre. Link to post Share on other sites More sharing options...
bertiedog Posted November 11, 2011 Share Posted November 11, 2011 I apologise to Ultrascale if they are moulded into a slot, I have never removed one, but was told they were identical to Gibson, which I have had apart. Exactoscale are different, but very specialist P4 society items, and need no pullers, just a quartering jig and slight pressure. Stephen Link to post Share on other sites More sharing options...
