The Wiscasset Waterville and Farmington Railway Museum is building a copy of the railroad's original Wiscasset, ME turntable. The original turntable was a 48' wood queen post turntable designed by the Portland Company. Our turntable pit design is a blend of the Wiscasset and Albion turntable pits. Albion was the railroad's northern terminal and had another Portland Company turntable. Except for the excavation work all the labor has been performed by museum volunteers. Our contractor started excavating for the foundation on 7/13/16 and we finished all the site and foundation work 9/1/16.

I'm just copy and pasting my posts off the wwfry forum. The pictures start with the timber delivery and cover up to the present date.

Some pictures of the original Wiscasset turntable. The original turntables did not have a continuous ring rail at the outer edge of the turntable. There is a continuous inner ring rail under the center of the turntable that forms the bearing assembly the turntable spins on. The outer ring rail is only present where tracks connect to the turntable bridge. In the pictures of the Wiscasset turntable the "pit" originally had a timber retaining wall that was later replaced with concrete. The Albion turntable had nothing around the pit area just the ground sloping into the pit area. Our turntable at Sheepscot will have concrete bulkhead with a piece of ring rail in front of the roundhouse and turntable lead area. The rest of the turntable area will be open like the Albion turntable pit.

You can see the outer ring rail ending past the the last track in the foreground.

Image

You can see the wheels holding up the turntable on the inner ring rail in this picture.

The earlier timber retaining wall.

3/9/16 Wayne delivered the turntable castings today.

Image

Image

4/27/16 We pulled up track 7 today to make way for the turntable. What's left of track 7 will be realigned to become the turntable lead from the yard.

Image

Image

Image

5/26/16 Douglas fir timbers for the turntable arrived in Sheepscot this morning. We still have some oak timbers coming for the queen posts and some other parts.

Image

Image

Image

Image

6/9/16 Randy and Phil cutting plywood for the concrete forms for the turntable foundation. The steel rods on the trailer are for the turntable and B&SR 67 rebuild.

Image

Every cross beam is getting three coats of wood preservative along with the main stringers. The turntable won't stay green after a couple months the  wood will weather a shade of brown.

Image

7/9/16 More rebar was cut and bent today. I believe we only have one more set of hoops to bend up.

More gravel was placed in and around the hole to allow the concrete trucks to get closer to the forms. Today the forms were coated with release agent and a bonding agent was applied to the top of the footers. We also started drilling the main beams for bolts today.

Wow! That's impressive. Congratulations. Truly, a museum worth supporting.

Excellent work! A thousand years from now some archaeologist will find that and wonder what the hell it is.

The WW&F would like thank the Amherst Railway Society for a $10,000 grant to help pay for the concrete work necessary for the turntable project. Without their generosity, the project would not have gotten nearly as far as fast as it has.

For those so inclined to help support us, please check out our "21 Campaign":

I'm particularly interested in that Skilsaw with the chainsaw attachment to get through the thick beams. Is that something you can buy or did you guys "MacGyver" it? We are going to have to do cut through similar sized beams in the near future when we replace the deck on our transfer table.

Great work and excellent documentation. I was surprised the aerial photo from your facebook site wasn't included. And others with stored turntables would benefit from some financial info if you could share any with us.

Even those not building a replica would have to do concrete work.

The chain saw attachment on the worm drive saw is a Prazi Beam Cutter. Not the finest of woodworking tools but better than using an actual chainsaw. I started cutting the cross members with the Makita beam saw but flipping 12"x12"x12's over twice for each cut got old fast. It's important when using the Prazi attachment to use something for a saw guide and cut slowly otherwise the cut tends to wander. I just clamp a 12" speed square to the timber being cut for a saw guide.

The folks at the museum are really something special!

They did not mention that a lot of the wood for the table came from their own right of way. They do not call Maine the Pine Tree State for nothing!

P.S.
I hope all of you have fun at the Narrow Gauge Convention there this week!

Great project and remarkable progress! Can't wait to see it completed, and thanks for taking the time to post all those pictures for those of us who can't get there in person.

One question - no taper on the center bearing wheel treads? I know you're not turning big Berks on it, but seems like it would reduce wear and turning effort.

Red Heun took this picture while flying over the Sheepscot Yard area and posted the picture on the museum's Facebook page. I labeled the buildings in the picture and roughly outlined the future roundhouse location in yellow. The red lines are the tracks feeding the turntable. The redline all the way to the right is track seven. Track seven used to run next to the shop building but we cut the track back and relined the track to serve as the turntable lead. The track into the right stall of the roundhouse is a through track and connects into the carbarn yard. Coal storage will be located on this track behind the roundhouse. The original Wiscasset roundhouse had a run through track in the left stall. With our run through track in the right stall our roundhouse will be a mirror image of the original

Anyone visiting Maine should make time to visit the WW&F in Alna. This is the most progressive, positive, railroad restoration in this part of the country. At a time when other railroads are being torn up for trails, WW&F is rebuilding and extending. I should add, their Victorian Christmas celebration is a never to be forgotten event. Wives and children love it too.

Maybe this is part of future phase 2, but I am surprised you didn't put a second wall set 180 degrees out from the one you did for 2 reasons:

1. to support the bridge in case you go past center with a locomotive (assuming an oops doesn't happen.

2. to allow for you to stage a locomotive on a stub track opposite the Roundhouse stall, equipment is going into or coming out of, for movement of non-powered equipment or dead equipment, as you might not have enough room to balance a locomotive and the piece being moved within the length of the table. (something we have discussed adding at our museum). This is safer than towing the piece with a tractor or a locomotive on adjacent trackage.

Nice job either way, I remember how much fun it was handling the 16" saw when we dapped our oak turntable timbers, oddly enough there wasn't a line of people wanting a turn with the big saw. Mainly it was just me and the saw's owner that used it.

Take care,
