General Discussion / Drop Box E-Mail Message
« on: December 01, 2016, 07:31:41 AM »
To All,

If you receive an e-mail from me (Dave Crow PE), that mentions a file within Drop Box, PLEASE DELETE the message!  I received an e-mail from another museum member and I trustingly tried to open the attachment - since it is close to the Christmas holidays, I figured it was an electronic Christmas card.  Nope, I had phone calls and e-mails from several folks on my various e-mail address books, so it is not good!

My three e-mails are:

david.e.crow AT parsons dot com
dcrow1050 AT aol dot com
dcrow1050 AT yahoo dot com

My work laptop is now quarantined from the corporate server until the gurus can come in and scan the hard drive for anything nasty.

I am truly sorry for this inconvenience.

Work and Events / Residing the Carbarn/Shop

Stewart, for the carbarn residing from T-111 to B&B, did we cut battens from extra boards by trimming the shiplap edges off and then cutting the boards down to batten width?

UK (Welsh, British) Two Footers / Brecon Mountain Railway No. 4
« on: September 18, 2013, 09:07:26 AM »
I surf the Welsh web sites to look at the progress on their lines.  While reading the Brecon Mountain's locomotives page, I noticed the description of No. 4:

"No.4 'Forney Type' Locomotive
This again is a new locomotive which we are building from the original Baldwin USA drawings of No 10 Ex Sandy River Railroad in Maine.

The original loco was scrapped in 1936 when that railway closed. It is a 2-4-4 T Forney type.

Work is well advanced and it is expected to start construction of the boiler in early 2014."

How similar was Sandy River #10 to WW&F #7?


Are there any public-domain photos of the Trout Brook Bridge available?  A 45-year bridge expert in my company just retired; he's a railfan and is willing to work on bridge projects that, in his words, "being in retirement mode, I will only accept projects that are fun and require a limited amount of time (8 to occasionally 20 hours per week).  One major retirement criteria is that I will not accept any deadlines, but, if it is indeed fun, I will not be able to stop myself from working on it so I may actually be quite fast."

Or, do we already have the design developed in adequate detail for all necessary permits, etc.?

Work and Events / Rail Machining for Frogs and Points
« on: February 03, 2013, 12:28:44 PM »
I spent yesterday in the machine shop at the Baltimore Streetcar Museum cleaning up the 96" bed Cincinati mill, getting some tips and pointers on setting up the parts, and finally starting on the first rail.  While the bed is 96 inches wide, one can only machine over a distance of 62 inches; trying to go beyond the stops might cause this big monster to tip over!  And that would be VERY bad!

The first step was to make a slight bend near the end of the rail - just under a foot from the end - so that the web of the rail extends all the way to the "point" of the frog.  After several passes in the hydraulic press, we got the dimension we needed, just under 3/4 of an inch.

Next was to clamp the rail to the bed of the mill and set the proper angle to machine a notch into which the other rail will bolt to form the rest of the frog point.  Using a 1-1/2" cutter we started making the notch; we could take 3/8" at a time with coolant and the proper bed travel rate.

Attached are several photos.  The last one was at the end of the day; I need to acquire a 1-1/8" cutter so as to make the final 9/16" radius corner of the notch.

The next work day will be this Friday; I believe Wayne Laepple might come down to lend a hand, as it takes two people to operate the hydraulic press - one to hold the rail, and one to operate the press.
