10 USRA Mikados

Post by hwboivin3 »

Started a group build of 4 Mikados with Brian Tusin and two others. I wanted to wait until I had some pictures before I
posted. So, here's the first update.

The frames were Laser cut and Blanchard ground to .812.

We have to decided to not use Railroad Warehouse castings early on and since they no longer supply them, it was definitely the right choice. I have a bridgeport cnc and soon to be two. So, I am planning on making most of what was a casting out of steel.

Here's more pcs

The frame crossties are made from 1/2 thick steel. I didn't particularly care for the thin casting design.

The Pilot Truck Frame. These were fun to make. The finish program was 12hrs long. I set a piece up, went to work and it was done about 10 mins after I came home.

Instead of bending the lower pilot braces, I opted to machine them. They worked out well. About 30 min total per piece and an hour to make the fixture. Plus a pic of the pilot truck so far.

Nice work, these are great engines. I would like to build another one someday if I could find some castings that were reasonable.

You must be accumulating one serious pile of swarf. Your finished product looks outstanding.

Swarf! You made me dig out my dictionary on that one! And yes, I typically fill a 5 gallon bucket per week, but not all from train parts.

Swarf.... I've never heard that word before, I'll have to remember that one.


Tim, no help from me on castings except for the 2 castings from Dave Sclavi. Nice quality , reasonable price, speed delivery. Railroad supply currently has some and in process of making more, but .... Brian Tusin had problems with them with well over 6 months for delivery etc..

I always see the USRA Hvy mikes. Does anyone build the Light mikes? Many roads used them and they would be a pretty engine.

You've never heard it because it's poor use of a word for the operation at hand. That, however, may be a "regional" thing.

Take note that when you read information on large CNC machines, a "chip conveyor" is offered. Not a "swarf" conveyer.

The word swarf generally applies to very fine particles---swarf being the waste material generated by the grinding process, for example. Some nations (and/or individuals) apply the word across the board, to represent chips as well. It's much like the word "tram", which is totally foreign to me as a journeyman machinist. Information I've read indicates it is a term that had its origin in steam ----- when tramming was setting timing on engines. Trammel points were used, thus one "trammed" the engine.

I use DTI when truing the head on a mill----not trammel points. I "dial in" the head. I don't see where tramming applies.
