Re: Building the Frisco 1522

Anyone who has been through this process knows the truth in that statement!

Re: Building the Frisco 1522

The latest parts created were the equalizers. These were water cut when the frames were made and needed to be thinned down shaped and drilled. The equalizers rock back and forth against a round bearing surface which still need to be created. The prototype actually varied the pivot point a little off...

Re: Building the Frisco 1522

One of the more unpleasant jobs so far is the cleaning up of the castings and removing all the flashing and parting lines as best as possible. Its noisy, dirty and I've been putting it off until the weather warmed up and I could move this task outside. The trailing truck was in pretty poor shape and...

Re: Building the Frisco 1522

With the cradle frames completed I went ahead and machined the cradle casting. Ran into some really hard deposits in the cast iron. I took the cutting edge right off a pretty large high speed steel end mill. So out came the carbide. With the cradle somewhat complete I found the urge to great not to ...

Re: Building the Frisco 1522

With the frames almost done I've turned my attention to the cradle frames. For this build I had the cradle frames water cut at the same time as the frames. The trailing truck axle sits back an exra 1-1/2" compared to the Heavy Mikado so I couldn't use the cradle frames from Railroad Supply. Also the...

Re: Building the Frisco 1522

I've been making more progress on the frames. After the pedestal binders were built and fitted to the frames I was then able to cut out the webs between the journal pockets and start milling out the pockets. I was also at this time that I drilled all the holes in the sides of the frames. The drillin...

Re: Building the Frisco 1522

That’s the only place that I know it can be accommodated as the bearings are pressed on the axel and there is minimal clearance between the journal box and axle (about a thou it two at most). 0.020” just sounded excessive but makes sense if shimming. The prints call for a slip fit between the bearin...

Re: Building the Frisco 1522

Was kindly PM'ed with information noting that the driver journals were made 0.020" undersize to allow for the use of shims to accurately center the axel in the pocket. It doesn't list what the final clearance should be, Just says things should move freely with no binding. Found the note on the assem...

Re: Building the Frisco 1522

Thanks Dan! Appreciate the correction.

That was a name and address I pulled from an old post so glad to know it is still correct.

Best

Re: Building the Frisco 1522

Another subproject underway is the modeling up of the Scullin Disk driver that I need to get cast. I modelled up the driver in Fusion 360 and I'm hoping to cut the pattern out with a CNC router kit I'm putting together. This will be my first venture into getting something custom cast. I allowed plen...

Re: Building the Frisco 1522

I've been working on a few different things lately. One of the items has been the main journals. When I purchased the castings for the Railroad Supply Heavy Mikado the main journal castings were not available so I had to come up with them myself. Plus my frames are different the journals are a littl...

Re: Building the Frisco 1522

That’s good to hear my thinking isn’t completely all wet. I’m working on the maIn journal boxes now and the RRSC prints list a 12” inch radius for the insides of the flanges. This requires more clearance between the flanges and frames to prevent binding as the axel pitches to the extremes in my mind...
