Re: Marking gauge?

...I've seen thin sheet cut by scoring with a skrawker (like an Olfa cutter ground from old hacksaw blade) and snapping, like plastic. Still needs cleaning up though. That's the way to do it. Hold the sheet between two steel rules in a vice with the skrawker line just showing and you can break off ...

Re: Marking gauge?

I think spring dividers are nearer the marks for this job, like the ones from the same supplier a bit further down the page. However I don't think you're going to avoid using a file to finish the job. You're unlikely to be able to cut smoothly and accurately enough to give you a reliable width (at b...

Re: Brimsdown-The last grand project.

Back in the day when peole were a great deal less fussy about fitting realistic tie bars to points I too had switch blades solder to a PCB stretcher/tie bar. The solder joint was indeed inclined to fail. The solution was to reinforce the joint with a little L shaped piece of thin metal strip. I used...

Re: Rigid Chassis Locos?

For me this is not really to do with a propensity, or otherwise to fall off, the real problem is electrical pickup. So a rigid 0-6-0 chassis is likely to have no more than 3 wheels in contact with the rails, so that's just one on one side or the other. Your loco then becomes very sensitive to dirty...

Re: First chassis in P4

The simple solution, surely, is to have a central fixed pivot/bearing point over the rear axle. The axle hole in the chassis frame would need to be narrowed so the axle can move vertically but not horizontally. Net result 3 point compensation with no fixed axle.

Of course you do realise that the wire isn't supposed to go through the holes in the fence posts.
