Rob G.

I replied to your request for some additional photos of the fixture but the reply is still sitting in my outbox of the PM after 5 days.

Re: Constructing The Josslin NYC Hudson Lead Truck

For completeness, the axlebox side slot shaving operations in photos and a verbal description. As stated previously, the cutter must only be swung back and forth by hand throughout this operation. The cutter is operated to shave down a slot wall advancing with 0.001"-0.002" horizontal increments per...

Re: Constructing The Josslin NYC Hudson Lead Truck

I normally don't do this here but I am including a couple of photos of the special shaving tool needed to relieve the side slots on the axleboxes. The semi universal holding fixture was made from a couple of commercial tools which I had. It allows the grinding wheel to relieve the cutter bit in two ...

Re: Constructing The Josslin NYC Hudson Lead Truck

A little further along.

Now that all of the lead truck axlebox frame opening slots have been machined, the next step is to relieve the side slots.

How I do this is quite interesting.

Re: Constructing The Josslin NYC Hudson Lead Truck

The first real operation is to machine the side slots in the axlebox blanks to precisely fit the frame axlebox openings. Select the surface ground side to be against the solid vise jaw then center the end mill over a side. To do this I use a graduated scale having a drill angle stop, an eye loupe an...

Constructing The Josslin NYC Hudson Lead Truck

Nothing like jumping around wildly and not doing what I said I was going to do next but that is just how I operate sometimes. I have built two and one half of these lead trucks to date. The first completed lead truck is on the Hoffman Hudson here and it does not have the added on brake lugs. The sec...

Re: A Real Dirty Job

To finally finish the re-building of the lead truck. Slotted the top of the last two axleboxes and painted the remaining two wheels as described previously. Only when I pressed the assembly back together, I noticed that, obviously, the original constructor had not bored the center hub axle holes squ...

Re: A Real Dirty Job

Next, reassemble the painted wheels/axle boxes/axle assembly. Ensure that you have all of the component orientation marks set correctly to keep the assembly as it was originally. Press a wheel back on an axle and check that the gauge is correct. For 3-1/2" scale, the inside wheel back to back distan...

Re: A Real Dirty Job

After slopping the paint everywhere on the front faces of the wheels and letting it dry (the Halogen hot bulb lamp did speed the high heat enamel paint to dry faster), a lot of paint now had to be removed where it was not wanted. Where excess paint ended up on the wheel tread, it was removed by soak...

Re: A Real Dirty Job

Next job was to repaint the lead truck wheels prior to re-assembling them. I admit it - I don't like painting - I don't have the proper painting/spraying equipment or the technique and I don't spend the necessary time on this aspect of the project. So don't ask for any advice here; my painting looks...

Re: A Real Dirty Job

The next operation involved machining slots in the top of each of the bronze axleboxes to hold captive the ends of each equalizer. The slots were made 1/16" wide and 0.078" (5/64") deep. First, carefully locate and mark where the end of each equalizer sits on the top surface of the axlebox when they...
