I'd say .030" is definitely worth fixing. Country: USA | Posts: 6794 Orionvp17 Fireman Premium Member Posted - 06/21/2020 :  2:12:56 PM     Looking Good, Dave! Another "check gauge" to use is your ears. If you can run an appropriate truck through the crossing and not be able to hear when it goes through, then you're golden. If it clicks, groans, rattles or whatever, then you still have "issues" that will manifest themselves only when you have visitors.... Don't ask....

Looks OK! dave Modeling 1890s (because the voices in my head told me to) Country: USA | Posts: 8831 railman28 Fireman Posted - 06/21/2020 :  5:12:34 PM     It does look good Dave. It's coming right along. Bob It's only make-believe Country: USA | Posts: 5707 Michael Hohn Fireman Posted - 06/21/2020 :  6:57:59 PM       Excellent! Country: USA | Posts: 7189 deemery Fireman Premium Member Posted - 06/21/2020 :  8:13:32 PM     And assembly is DONE! I tested this by pushing some standard gauge cars through the crossing, no problems. Then for the narrow gauge, I took a truck and started it uphill from the crossing. It rolled down and through the crossing with no problems. It also passed the Pete Test with no unexpected noise. There are clicks as the wheels go over the gaps, but no one click sounds worse than the others. Before I installed it, I took a variation on the older carpenter trick to check how smooth/aligned a joint is. I put blue dye on the rails, then ran a sanding block over the crossing to see where the low spots (that kept the dye) were. Then I filed down to where most of the dye was finally removed. The rails will need to be polished after all that abuse, but at least I know there are no high spots to pick on a wheel. I washed the entire crossing in water, then scrubbed it with acetone to remove the residual dye and any flux, etc. dave Modeling 1890s (because the voices in my head told me to) Edited by - deemery on 06/21/2020 8:36:14 PM Country: USA | Posts: 8831 BurleyJim Fireman Premium Member Posted - 06/21/2020 :  9:38:12 PM     Machinist's trick Dave, carpenter's were only allowed to use pencils.

Bruce Country: USA | Posts: 33265 deemery Fireman Premium Member Posted - 06/22/2020 :  11:46:03 AM     The question of the day is how to add more PC Board ties and cut the gaps so the assembly remains strong and in alignment. Here's my current thinking (red lines are the gaps) Each corner of the crossing is its own 'electrical section'. I think if I add these PC Board ties, they'll be sufficient to hold everything together. Because of the brass shim underneath the crossing, I'll have to substantially file down the back side/reduce the thickness of the PC Board ties underneath the center of the crossing. dave Modeling 1890s (because the voices in my head told me to) Country: USA | Posts: 8831 jbvb Fireman Premium Member Posted - 06/22/2020 :  1:08:23 PM       If you cut on the two straight lines, you divide the diamond into three pieces. I suggest you trust the gaps you've cut into the copper of the ties and stagger the rail cuts so the outer long ties can hold things in alignment. Also, to your question in the Lounge, I'd glue the wood ties to the roadbed, check the fit by putting the diamond in place, then cut the gaps while the glue dries. Finally, spike the diamond to the wood ties and complete the installation. Country: USA | Posts: 6794 deemery Fireman Premium Member Posted - 06/22/2020 :  1:12:39 PM     Yeah, I realized that as I looked at it some more. So here's the latest gap & PC Tie plan: I'm not sure I can cut those gaps with a Dremel wheel with the crossing in position. My strong preference was to cut them using my jewelers saw, but I'm still pondering how to make the cuts. I don't want the Dremel disk to cut the PC Board ties. Maybe the plan is to do the cuts in the diamond on the workbench, and then do the cuts on the running rails on location. Or to take BurleyJim's idea to solder keepers on top of the rail before making the cuts... dave Modeling 1890s (because the voices in my head told me to) Edited by - deemery on 06/22/2020 1:19:17 PM Country: USA | Posts: 8831 Page: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 of 53 Topic    New Topic |    New Poll |   Reply to Topic |  Previous Page | Next Page Jump To: Select Forum Railroad Line Administrative Forums       Forum News       Administrative Posts General Forums       WorkShops, Garage, Machines and Tools       The Tour Bus       The Arrival Track       RR-L Member Personal Websites       The Crew Lounge       The Classroom       Interchange Tracks       Rail Events       Reference & Research Model Railroad Forums       The Sn3 Branch       Mike Chambers' Craftsman's Corner       HOn30 and HOn3 Forum       Early Rail Forum       Dead Rail Forum       The On30 Line       Railroad Photography Forum       Small Scale Model Railroad Forum       Mid Scale Model Railroad Forum       Large Scale Model Railroad Forum       Logging, Mining, & Narrow minded       Model Railroad Construction       Micro & Mini Layouts       Layout Design / Operation Sig Forum       Startin' from Scratch       DCC, Computers and Electronics for Model Railroads Shop Talk       Vehicle and Non-Rail Transportation Modeling       The Steam Shop       The Roundhouse       Rolling Stock: the Car Shops       The Diesel Shop Company Store       Railroad-Line Swap Meet       New Product Announcements Fallen Flag Railroad Forums       Erie / Lackawanna Railroad Forum       Raritan River Railroad Forum Railroad Software Forums       Atlas Right Track Software       Railroad Line Software Library Model Railroad Club Forums       The Model Railroad Club Forum Sponsor Forums       Rusty Stumps Scale Models       KingMill Enterprises Railroad Line Weblinks       Badger Creek Lumber Co.       Central Missouri & Southern RR       Raritan River Railroad       Thor's All Gauge Page  -------------------- Home Active Topics Frequently Asked Questions Member Information Search Page Railroad Line Forums © 2000-2020 Railroad Line Co.
