I'll be up for the fall work weekend. I should have the pistons and piston rods for #9 done by then. Ed G is coming by this weekend (storm warnings aside) to help get the VERY tight bolts out so that I can remove the rings and machine the pistons down to match the new bores. Jason, Have some stuff ready for me to machine while I'm there. I'll be happy to but some muscle on a shovel if needed.

See you in October!!

Journal boxes in the 2 foot gauge size could easily be made from bar stock. If they were going to be cast, I would make them of cast steel. This gives the shop folks the opportunity easily to weld them up if they break or get worn. Even wheel centers and truck frame parts should be made from steel castings for the same reason - ease of repair and rebuild when necessary. In the journal boxes I repaired for the 0-6-0 I am working on, I chose to use continuous cast bronze tube for the crown brasses. With the aid of a CAD drawing, I figure out the ID and OD of the material so that I can get 2 brasses out of a round tube. This cuts the material cost by 1/3 since the brasses go a little more than 1/2 way around the axle.

Bernie, Beautiful pattern work!! It was nice to see you up at ST. Wish I had more time to chat with you. Maybe next time.

I will be bringing up a tool post grinder and if all goes well, I may be working on getting the driver journal surfaces trued up on the #9 drivers. If time allows, I will take a look at fitting the driving box brasses to the axles.

 A pair of "disconnects" might be a good idea. They have a low load height and a fully adjustable ta handle any log length. Be careful with loading logs. They can get away from the handler and make a mess of whatever/whoever might get in the way. A flat car mounted grapple with a single operator might be the safest method. A simple portable hydraulic pump could be the power source. This would be handy for doing other remote work as well.

Is there a set date for the Christmas event? I would like to bring my wife up to Maine to show her where I have been enjoying my spring and fall weekends.

Great pictures Stephen. I wish I could have been there for the fall work weekend. Is a date for the spring work weekend set yet? I don't want to miss it.

25 foot reach?  I am having visions of an even "BIGGER" Joe.

 I brought my DR mower up this past weekend and ran out of time to give a demonstration. The big lathe is all lined up and I put some time in helping with the rail car. Dana took a quick look at my DR mower and may now have some ideas for a ROW mower. This flail mower seems like a good piece as well. A good sized counterweight may be necessary.

What will be happening next (Sept. 30- Oct.3) weekend? I'll be up with Ed G. for the weekend. I just want to be prepared tool wise before steaming my way up to Maine. I'm bringing some parts for the lathe and my walk behind brush mower....so far.

Gordon,

I'm not sure exactly when I will be coming up this fall but when I do, I will bring my older machine with me. The newer model has air tires, a lower center of gravity and a forward-reverse transmission. More advanced than my older model. You will be able to see how well it cuts and if the basic idea will work for you. These machines have a dead-man control so if one does release the handle, all motion stops.

The company is located in Vermont. It may be to the museums advantage to see if they would have a demo unit for the MOW team to try.

Glenn,
 Thanks for the offer. I may just take you up on it. I will be done with the parts for the bog lathe in the next day or so. If I find it may be a while before I can get up to Maine, I may have you bring the parts. My friend Ed may be visiting me sometime this fall, and I could send the parts with him. I may even get up there sometime this month. Either way, I'll keep you in mind.

Mike,
I use my DR to mow the pond ban, model railroad fills and drainage ditch sides around my property. It has been at a 45 degree angle and sill moves right along. It has a low oil shutoff switch so if the oil pump does suck any air, the motor immediately stops. 

 On a 1;1 slope, even a human with a weed wacker would have a tough time standing. I have seen the ROW up there and most of it could be mowed with a machine like the DR mower. Keep in mind, will will not mow the 5-6 inch diameter stumps that are still sticking out of the ground, but it will handle any 2 inch saplings with ease.

Have you guys ever used a DR Field and Brush mower? I have an older version of one of these and it handles anything I can run over. The newer models even have reverse (mine does not) so mowing the tough spots are quite manageable. The two behind version might work well to.

It's been a while since I posted here and here is a good place to get back into the swing now that summer is over.

 As Jason mentioned, the material used for the pins was chosen for it's characteristics. It just so happens that it's the same material used for axles. Also, it was about the same diameter for both parts. Originally, I was to make all of the the axles for #11. It was later decided to make the crank pins. So I just used the chosen material to make the crank pins instead.

Great work on the patterns Bernie. Am I sensing another circular "backshop" style BBQ in the spring?. Right now I am making parts for the big lathe at the WW&F shops so that future projects, like #11's wheelsets, will go smoother. I will be coming up this fall to get that machine back in running order. My buddy Ed G. and I plan to spend some time on the machine improving some of it's less than desirable traits.

 Removing 1/4 to 1/2" of material from parts as big as wheel centers is not a big deal. When not in mass production, it's better to have more than enough material to machine off rather than not enough. This eliminates some of the "we shoulda' left more meat on in that area" discussions. It's far easier to take material off than to add some on.

 As far as taking time away from the #9. Like someone said, it's easier to make parts from afar to engineered drawings for a new locomotive that will be built from scratch where known fits can be predetermined.  I live in PA and to travel to Maine for more than a couple of weekends a year is difficult for me. I have a desire to help the WW&F museum achieve it's goal by offering my machining experience. I can do that by making parts here in PA and bringing them up when I can or shipping them with someone who will be Maine bound. The #9 is up there in Maine and many of the parts are already there awaiting rehab. This rehab requires having the mating part(s) on hand to check for fit and operation along with decisions being made on whether to make new parts or reuse the old ones.

 Also, to have a big part of the #11 on hand is good incentive for some to keep the project moving forward. It shows that the museum is serious about building the #11. In the not for profit museum world, this is a good "seed" for getting the funding needed to keep the project moving forward. When benefactors and granters see their donations become something tangible, they feel good about donating again.

 Time to go off to the shop and make some chips.

Looking forward to my next visit.

James,
If you could do a review on the spring work weekend, I would greatly appreciate it. Although not an operator (yet) I would like to learn the rules of the WW&F so that I am aware of operations as a safety measure while working out on the line or in the yard. One of those "it doesn't hurt to know, but it might hurt if you don't" things.  Thanks.
