Tom Mallard’s Workbench L&B Manning Wardles in 7mm scale

Cast iron as a material may not take too kindly to broaching, especially if the wheels are to be broached full depth of the axle hole. I'd be wary of splitting a casting or wheel boss. I assume Tom is replicating some vintage practice.

Expanding on Adrian's suggestion of using a taper reamer - the taper at the end of a regular hand reamer would suffice.

(Hand reamers are easily identified by having a square at the end of the shank. Machine reamers have parallel flutes full length and no square on the shank.)

It was ‘vintage practice’. Bond’s, Leeds Model Company and others all used a system where the wheel had a square central hole for quartering but the square hole was only about half the depth of the wheel. The end of the axle had a screw thread and the outer face of the wheel boss had a recess for a slotted nut that was used to secure the wheel. It meant the wheels could easily be removed and replaced (e.g. for replacing the mainspring in the motor) and the quartering preserved.

Hello again,

here's a short update and snapshot of the L&B Manning Wardle project. So many little things needed either making or attaching (I'd avoided all the oilpots and lubricators - 4 types on the cylinder assembly! - plus completion of the cab fittings' installation til now). There was also the small matter of making the things run smoothly with all the properly working Joy valvegear...

Proper photographs will be done soon, but I was excited to show where these two had got to after a long gap in updates. The weathering is much needed now to highlight the small details and bring them properly to life.

The madness of the lone model maker exemplified in narrow gauge form.

Best regards

Tom

They do look stunning - be great to see them when weathered.

Top drawer Tom, stunning models!

 

[Giles]

Quite exquisite! There is nothing at all to give away what size they are. They're going to be someone's absolute pride and joy!

 

[Hawkeye]

As good as it gets. It has been a joy to follow this build.
