Re: 3/4" Scale J1e
Because the big guys don’t have a washer and nut with cotter pin holding the trucks to the rolling stock frame.
In a derailment once enough separation occurs to pull the pin out of the bolster the truck just take off. There are plenty of derailment photos showing the trucks in every dimension imaginable.

Or an employee with a big enough wrench to tighten it
Too many things going on to bother listing them.
Re: 3/4" Scale J1e
Heh! That makes sense! I suspect that the chain wouldn't serve much of a purpose in a derailment in keeping the truck properly oriented. It would break all too easily, as would the attachment, but it would most likely serve adequately in keeping the truck from moving far enough for the pin to disengage. All depends on what the car is going through in a derailment, I suspect.makinsmoke wrote: ↑Mon Aug 15, 2022 3:57 pm Because the big guys don’t have a washer and nut with cotter pin holding the trucks to the rolling stock frame.

That said, is it safe to assume that a safety chain was attached to all four corners?

Re: 3/4" Scale J1e
Hello My Friends
Yes there will be working brakes on the tender. Clasp brakes with two brake shoes per wheel. Here is a drawing showing the general arrangement. I have made all this baloney in 1-1/2" scale. On both Buckeye, and commonwealth trucks. It will be a real hoot to make in 3/4" scale. Clasp brakes work amazingly well. Sorry the drawing doesn't reproduce well here. There are four safety chains per truck, one on each corner. Totally unnecessary on a model. But then, the entire model is unnecessary

Jack, I think you’ve given me the best line for people who ask what I do in my shop. Something totally unnecessary
Re: 3/4" Scale J1e
Depends on one's objective. If a faithful model of a prototype is intended, each and every detail is important, including surface finishes. You've done an excellent job of providing these details in my opinion.
Does anyone know why they were eventually abandoned? Was it an economic decision, or did they fail to live up to expectations?

Re: 3/4" Scale J1e
You`re absolutely right! All which is necessary to have working engine are 4 wheels and a fat boiler
By the way, Jack: The brake rigging of your J 1e -tender is very similar to that of my A. Such a lot of parts to mame, mostly 12 or 24 of each type But a brake working perfectly as the result, so
One question: I found no hand brake at most of the US tenders? They were very common and (helpful) in Europe and used the same rigging by means of a lever or hand crank. Thus I decided to add such a device to my tender for inhenced safety. Other ideas?
Best regards

Brakes on my 3/4". Hudson tender are for parking only...since as you say...they work very well.

Hi Jack
Amazing work as usual. I though I'd share a couple of picks of my fathers work in 1" scale in the late 1950s I road on this engine sitting in front of dad on the tender in the early 60s.

Hello My Friends
Here is a drawing of the type of brake cylinder that I will be making. It has a several interesting features. First it utilizes toggle bolts to hold the cylinder heads in place. It has a clevis on the end opposite of the piston rod. It also has a hollow piston rod. I'll explain that in a minute. Here is a drawing showing what the clevis is for. The two brake levers are tied together by the brake cylinder, and a turn buckle for adjustment to take up slack in the rigging. The outer end of the brake levers is linked to the equalizer beams. Also notice that the brake cylinder has a hollow piston rod. This last drawing shows why. Inside the hollow piston rod is a floating push rod. This does two things, it directs the pushing force to the piston, and allows the clevis end to move in an arc with the brake lever.
Just some things I thought you might fine interesting.
Have A Great Day
