Does the bridge still need to be narrowed?  If so, what will be the process to do so?

Harold, thanks for the clarification.

Harold, the "cups" in the ends of the carbody in which the ends of the truss rods and tensioning nut go - are those castings?

I'm sure Josh Recave will be able to determine the minimum size required for the electrical distribution building, based on the National Electrical Code's minimum access requirements in front of the equipment.  If the panels or other gear have rear access then the Code has clearance requirements as well; you're talking at least 3 feet in front of the equipment at a minimum.  And... nothing can be stored in the access space in front of the equipment.

Just my two cents.

Would there be any copies of station registers showing freight shipped or received in Two Feet to Tidewater?

Glad to hear your friend was able to access Coach 8 for a ride.  Maybe you need to have him come back and see how much of the campus he can explore.  And there are several levels of that exploration; how many places he can access, and compare that to how many areas he can access comfortably and easily.  Wendy uses both manual and electric wheelchairs, and while she can get around, a lot of bumps cause her back pain due to the jolting.  And pain can be a major deterrent for keeping wheelchair-bound folks away or from enjoying the total experience we are trying to offer.

Off my soapbox now.

Do we happen to have a copy of the order that was placed with Jackson & Sharp for Coaches 2 & 3?  Possibly the colors for everything would be on either the order itself or on the order confirmation from J&S?

Just a thought.

Many of the pressed glass patterns can be sourced through stained glass supply houses; older commercial glass houses also have a lot of specialty glass options available due to old home restorations and other architectural demands.  Baltimore Streetcar Museum has used Chaudron Glass for years; I remember looking through books of glass samples when researching "ripple" glass for one of the streetcar restorations.

Harold, it appears your patterns for the dies were a large part of the reason the formed sheet looks so good!  Congratulations.

Bill, the following are some photos of the baggage section of the SR&RL combine in Portland.  These are the slats to keep parcels and boxes from jamming against the door.  Also included is what the door from the passenger to the freight section of the combine looks like:

See you in a couple of weeks.

Bill, normally there are a set of vertical wood slats inside the baggage area into which the door slides. These slats probably kept the baggage person from stacking or leaning items such that the door could not open. In any case, they would block the view out the window.
I believe our caboose has similar sets of vertical slats as well, if you need a reference. I can send a photo or two on Mobday when I'm back at my computer.

We have a smaller version of the same mill - with a similar adjustable-angle head as well - in the heated portion of the shop; right now it is cutting babbit to the proper radius for a replacement bearing.

Thursday, April 6th, Wayne Laepple came down to Baltimore to work with me on the switch points; we also had a session on March 9th.  The second set of points have the first several machining steps complete: both sides of the head machined to 15 degrees (wheel side) and 6 degrees (mate side with stock rail) as well as the one side of the base machined off in line with the 6 degree taper so it can nest up against the stock rail.

Yesterday we machined the base off of the left side point and then flipped it on its side to start the tapered undercut so the point can rest up on the stock rail.  We managed to undercut a little under 6 feet of the point, but either a second set up on the mill or judicious use of an angle grinder will be required to finish off this point.  I plan to undercut the right side point next week; the points can then come north for final tweaking before installation.

A second pass undercutting the base of the rail:

An end shot (not the best photo quality) showing the undercut:

Thanks again to Wayne for coming down to Baltimore to help out with the machining!
