Re: Chas. V. Arnold Tiny Power Northern

I think that I may have answered my own question. From deep within my files.

I still don't know what happened to this locomotive though.

Chas. V. Arnold Tiny Power Northern

Does anyone know the history of or know what happened to the 3.5" gauge Northern which Chas V. Arnold of Tiny Power constructed? I know that it appeared in some of the original Tiny Power's catalogues and the all copper locomotive boiler was pictured in the book Chas wrote on miniature boiler constr...

Re: Constructing The Josslin NYC Hudson Lead Truck

After slicing and grinding square the ends of all the leaf springs (17 in total), the next operation was to roll the curvature into the leaf springs (which was 3/16" setup on the bottom longest tripled leaves). Each subsequent leaf was then rolled slightly shallower until the next leaf became flat. ...

Re: Constructing The Josslin NYC Hudson Lead Truck

Back to the production of leaf springs. The starting sequence. As I have said before, the way one does this is often according to the equipment one does or doesn't have. For the cutoff operation, as seen in photo 714, one needs to have a controlled/firm grip on the material but do not push the cutof...

Re: Constructing The Josslin NYC Hudson Lead Truck

Drilling and tapping the lead truck frame brake lugs for the brake shoe hangers. The setup to do this was exactly the same as was done with the Langworthy truck frame. However, as the slots in the brake lugs were machined correctly this time, having the correct offset from the frame so that the cent...

Re: A Real Dirty Job

I went back to the 4 wheel trailing truck to make some additional items. On the trailing truck rockers, the Langworthy drawings say nothing about the rocker bearing plate projections which are needed to constrain rocker movement. I do have a book which shows this in a drawing but with no dimensions....

Re: A Real Dirty Job

Some newly machined brake linkages for the engine.

The lead truck reinstalled.

This locomotive has had the h..l run out of it. The locomotive is still very dirty and needs a good steam cleaning all over which it hasn't had yet.

Re: A Real Dirty Job

The final machining and assembly of the brake assemblies. The first three photos show the simple holding fixture made and the fixture in use to machine the I beam centre sections of the offset brake hangers. The final fitting of the offset brake hangers was a problem due to the hanger offset interfe...

Re: A Real Dirty Job

Pressing on, I first hand held and carefully roughed out the offset brake hanger outlines by band sawing followed by belt sanding. These parts become very trick to hold at this point so proceed carefully. Followed this by my " favourite" rotary milling operation - end rounding both ends of a hanger ...

Re: A Real Dirty Job

I decided that the most straightforward way to solve the two misaligned brake shoes was to machine a couple of offset brake hangers. I found that the problem lay with the brake lug slots which had not been offset correctly at the time the original brake lug slots were machined. I was not going to wi...
