Re: Bogie Control

Tim, I'd place the chassis on a mirror (this helps you see what's happening underneath) or a sheet of glass, surface table, anything dead flat and smooth will do. Slide the bogie from side to side in the manner in which it would move as it enters a turnout. If it slides smoothly raise it slightly wi...

Re: Quiet Please!

Following Tim's comments about a thin cork gasket, maybe you could simply slip some thin cork between the boards and the table, or even some thin rubber sheet. Might save you having to fill the baseboards with foam. Also, rubber underlay will help.

Re: Hornby Stanier to P4 around 3' curves

I will have to investigate on my Hornby Maunsell's.


Steve - take care here as the Hornby Maunsells are already a touch too high, although it hardly notices. I have found that with true wheels and the Hornby sprung close coupling they run beautifully anyway. Not a trace of wobble.

Re: Beer and Buckjumpers

Paul, Rather than make up new frames perhaps I could suggest folding up some strip into a U shape and soldering it all the way around the milled hornblock slots? if you use the right thickness of strip hopefully the High Level hornguides will slip in nicely. Seems a shame to waste the frames. Philip

Re: Really, really small collet needed...

My TBM220 came with a Rohm drill chuck, ostensibly down to 0.5mm but in practice I find it will hold 0.3mm. It's also dead true, so I've never thought about collets. Rohm's website would be worth a look. I understand that Sherline use Rohm chucks now on their lathes in preference to Jacobs. I've bee...

Re: Soldering iron problem

When I moved to an Antex Iron after many years of using SRB irons I found I just didn't get on with the iron plated bits. I had similar difficulties trying to tin them, and also the tips do not have clean sharp edges as they are dipped in the plating which gives a rounded edge. I like to pick up a t...

Re: Maunsell chassis and restaurant issues

The Hornby chassis is a completely separate item that simply unclips from the body/roof moulding. It might match the Kirk body, but bear in mind that that has a reduced tumblehome; come to that you might argue that Hornby's isn't quite enough either (nowhere near as bad), but perhaps we shouldn't st...

Re: Planning to buy a modellers lathe

Thanks to the efforts of Vincent (Camden Bank) Worthington, I now have a much rejuvenated Unimat SL lathe. You can tell it's old because it's got Selecta Unimat on the motor housing. The 3-jaw chuck was well past its sell by date, although there was no play at all in the headstock bearings. I know t...

Re: The path of less resistance? J72 conversion

I'm not a springing man, but on pickups there's only one rule. On every wheel at least on an 0-6-0 and if it's got a tender, at least two more on each side. The more pickup you've got, the less likely you'll have a stall or unsteady running. Two axles on a six coupled chassis is not enough, even if ...

Re: Crankpin problems.

Howard You're quite right, a metal wheel centre is in theory going to be stronger than plastic. But in practice, given the loads that we place on wheels, the right kind of plastic will grip a smooth axle and be plenty rigid enough. Gibson wheels, like Sharmans of old, are a bit more flexible than Ul...

Re: Coupling rod clearance

A drill will not produce a hole exactly to the size it says it does. I think it usually ends up a trifle oversize but in any event the drills that we usually buy are often slightly undersized. For example, I've just measured a 1.5mm (nominal) bit and it's actually 1.47mm. Which will probably give yo...

Tony, Clearance should be the minimum you can get away with, but this depends on how good your workmanship is, how accurately the rods match the chassis (yes, even with jigs there can be a few thou in there) whether the crankpin throw is exactly the same on all the wheels (not necessarily a given!) ...

Re: Converting a Conversion...

If the conversion set wheels have the extended bosses moulded on the back then of course you'll have to remove those. If you want to return to 1/8" axles you could always ask David Rogers if he would re-mould the centres for you.
