    Come on, now. That would be like finding the haystack in a needle! [:-clown] just kidding!
    I'll enjoy watching this project!!

      For some reason that last picture is not correct................

      No stock was removed from the thickness.........

      I see now after looking back at your pictures and the underside of mine, that you just removed stock from the lettering and hump that said "Made in China" on the underside. :erm: I see now, missed that subject lesson!

      At first I thought you cut a grove down the whole underside cover.

        Yes, that's exactly what I did. This allows the PC board to sit lower into the cover. The "hump" has a draft angle on it and removing it gives more area to the PC board to solder wires to.

        I'm thinking of epoxying the board to the cover instead of screws. Less to do to fasten the board. What's the consensuses of the guys following this thread? For - Against epoxying? Constructive comments welcome.

          Well, I personally think epoxy is the better choice here, for one it is an easier mounting fix and once applied it isn't like it would need to be removed at any time. You have it to where you can get to the cover mounting screws. And even if you needed to re-solder or replace wipers it can be done in place. Just my thoughts here! Lets see what others my think.

            Did a little research on 2-6-6-2 tank engines over the holiday. Sitting in an air conditioned camper trailer posting this. Will be heading home in a couple of hours.

            I wanted to see how the prototype engines had there drive rods mounted to the wheels. I found a nice example on BrassTrains.com. The high end brass engine use the same coupling as the prototype. The front rod is couple to the rear rod on it's own pivot. First though I think this is interesting how they pick up power from the rails. The front engines picks up power on one side and on the other side on the rear engine.



            Here's a close up off how the rods are connected. I'm going to attempt this some where down the line on this project. Also notice how short the screws are holding in rods on the wheels.



            That's it for now. Getting ready to leave in a couple of hours.

              Interesting find on the power pick-up wipers, however, I think you making it to where both the front and rear drives pick-up power from both sides of each is better in the long run for positive power pick-up. Don't you think?

              Also, have a safe trip back home. Hope you Holiday weekend was great.

                Yes, definitely having pick-up on both sides front and back is better. You'd have thought they would have used a piece of PC board instead of using separate pieces. But, I can see why they did it, easier to bend the pick-ups in a jig and screw them on then making separate wipers.

                Got home save and sound. Didn't go to bad, had many things to fix and it was hot and humid. Tomorrow I make hay. It rained here Sunday like crazy and of course that made the grass grow. So guess what I'll be doing for the next couple of days?

                  Bernd,

                  I'm putting off making hay but probably will do one field (front yard) shortly.

                  Meanwhile, your information here is going to be very useful as I think about reworking an MDC kit I did twenty years ago. It actually runs pretty good but I'd like to improve the pickup.

                  Glad you got home ok. I've been on the road a lot or I might have considered a trip up to Rochester to see family this weekend.

                  Mike

                    Hi Mike,

                    If you ever make it up here let me know. I'm actually 20 miles south of Rochester. The town is located on Rts 5&20. Give me a shout if your going to be in the area.

                    Trip home wasn't to bad. Traffic wasn't bad except for a few not so good drivers.

                    I've got a few Mantua's that are going to need wiper up-grades also. There on the list some where.

                      Wonderful photos of the Brass locos pick-up system and rod mechanisms. Why MRC/Model Power/Mantua built so much slop into everything is beyond me!

                        Precision costs money. I would think if one of those manufacturers held the same tolerances as on the brass engine the price would be a bit higher. I'd like to see the procedure they use to assemble those rods on MRC/Model Power/Mantua engines.

                          "Precision costs money"

                          Never were truer words spoken, in the brass example, probably about a $1000.00 more worth of precision. We have to ask ourselves, how much precision do you want to pay for?

                          I wonder what minimum radius the brass loco can handle? I'm not too worried about the rod slop, I do need to add electrical pickup as this thing is bad with #5 Peco dead frogs.

                            Bernd, Geared Steam, is correct'. Those brass babies are expensive.

                            And I would think well worth it. However, in O gauge, I just can't justify the cost. But I'm thrifty'...

                              How much money does rejected and returned products cost?

                              I would be surprised if the cost of better parts, actually cost anymore money to produce; but, even if they did, how much would it add to the $254.98 suggested retail price? $5.00...$10.00...$25.00?

                              Good luck, you guys!

                                Take a closer look at the rods, the screws and the pins holding the linkages together. Precision takes time and time X per hour wage = expensive. The rods on both engines are stampings. Doesn't take much time to punch out parts. Notice the side rods on the brass steamer are stepped. That take's time to machine. The pins to hold the linkage together are probably held to high tolerance dimensions. I'd have to say there's much more time spent on making those parts and assembling them on a brass engine versus the Mantua/Model Power/MRC engines. After all they have to keep the cost down on those plastic versions or they would sell.
