"Some lashing points made up from bits of scrap etch."

 

Say that again slowly, with diagrams and a scale rule...

 

I've recently built a whitemetal G&SWR wagon that came out with wonky axles. In 00 there's enough slop that it runs sweetly enough but I'm thinking of MJT inside bearings. However, previous experience shows that they can be a bit stiff, even after opening up the holes a little. Any thoughts?

I'm interested in your internal compensation units Dave, can I ask what make they are - or did you fashion them yourself?

Dave has widened the bearing area by soldering on some washers, Stephen.

They look like MJT units, Mikkel. I am sure Dave will be along soon to confirm or deny this supposition.

Ah, so that's the purpose of the washers on the MJT etch. I'd presumed they were for packing to reduce lateral movement. Perhaps I should have read the instructions, if any...

If we are lucky!

Yes they are MJT. the low height ones, though both sizes are useful. A sideways pic. Just solder it all up generously then run a 2mm reamer through it.  Perhaps not quite as free running as a pinpoint in a brass bearing, but their usefulness   is the key .  Dart castings do a good range . 

 

 

 

 

 

A couple  of pics of the Lashing points. Not very good pics, its at the limit of what I can see. The plate and O-- shaped bit are bits of etch. Shackle, bolt  and ring are 0.3 ns wire. Old fashioned lead solder and bakers fluid to fix it all together .  The trick is a fine pointed bit with just a tiny amount of solder on it, then be quick, you hear the hiss of the flux and then away. 

 

 

 

 

 

Oh, and a glass of cold water to plunge your nose in when you get too close..............

Thanks, that's ironic as I use MJT but didn't recognize them in the first shot. Maybe I should try using them as they are actually intended! 

Excellent work sir.
