joe123 Posted March 1, 2019 Share Posted March 1, 2019 Hi Is there anyone on the site that put the Magorail car system together? If yes would love to hear from you. Having a big problem with the chain tension. Cheers Quote Link to comment Share on other sites More sharing options...
0 Broithe Posted March 1, 2019 Share Posted March 1, 2019 If there's anyone who was involved with O'Connell Street you may get an answer, if theirs is Magnorail, of course. . Quote Link to comment Share on other sites More sharing options...
0 murrayec Posted March 1, 2019 Share Posted March 1, 2019 Hi I have some knowledge on Magnorail- What is happening? What length is the Magnorail chain? if over 1.5m do you have more than one motor? What are the radius curves your using? Any other info you can give may help- especially photos of the Magnorail layout Eoin 1 Quote Link to comment Share on other sites More sharing options...
0 joe123 Posted March 1, 2019 Author Share Posted March 1, 2019 Thanks Eoin for your reply. I am away from the lay out at the moment but I will get back to you ASAP. Thanks mate. 1 Quote Link to comment Share on other sites More sharing options...
0 joe123 Posted March 2, 2019 Author Share Posted March 2, 2019 Hi Eoin Sorry about the delay in getting back to you. I have the rail fully laid. And had the chain in place, with a temporary road bed laid on top. But I cannot get the right tension on the chain. Here are some photos. Thanks for your help.

0 joe123 Posted March 2, 2019 Author Share Posted March 2, 2019 Sorry Eoin forget to mention the full length of the rail is 610 cm. And I am using the two 12v motors . I tried to measure the radius of the rail, using the 18 inch tracksetta . See attached photo. Thanks. Quote Link to comment Share on other sites More sharing options...
0 murrayec Posted March 2, 2019 Share Posted March 2, 2019 (edited) Hi joe123 Thats a lot of Magnorail. When you say 'cant get the right tension on the chain' - what do you mean? Is the chain connecting up? or, Is the chain slipping? or, Does the chain run OK without cars on, and doesn't when their on? In the third photo I see a rather tight curve! for a curve that tight one should use Magnorail's return loop (modified) which will reduce friction. For 6 meters of soft curve rail you should have at least 3 motors- which may run up to about 6 cars. With the layout you have done and if you want to run more than six cars I would put a motor in per meter of track = 6 motors! If you use the return loop unit on the sharp bends or increase all sharp bend radius you may get away with 4 motors. Am I right in saying that you have two separate Magnorail tracks of 6 meters long each? If thats the case you'll need to up the motors on both! I know that might be not what you want to hear, but Magnorail is really designed for nice wide radius loops and small layouts!

0 joe123 Posted March 2, 2019 Author Share Posted March 2, 2019 Hi Eoin. The chain runs but then pops out of the rail. It’s one rail with 2 return loops at each end. I had all the chain connected up with a temporary road bed on top. No cars. But it keeps popping out of the track. Using 2 motors at the moment Quote Link to comment Share on other sites More sharing options...
0 murrayec Posted March 2, 2019 Share Posted March 2, 2019 (edited) Hi joe123 If the temp road bed is held down somehow so that the chain cant push it up that might help! The chain relies on the under road surface to keep it down when there is to much friction. The reason the chain pushes up is because of friction on the bends- the chain on front is going slower through the bends than the chain following behind, the chain behind will go where the least resistance is- that's up if it can push the road surface out of the way! More motors and return loops on those acute bends should help with countering friction- but do try fixing down the road surface first and test again. It would be best if the chain glides around without the road surface on! Eoin Edited March 2, 2019 by murrayec Quote Link to comment Share on other sites More sharing options...
0 joe123 Posted March 2, 2019 Author Share Posted March 2, 2019 I know what you mean Eoin. I will give it one more try and if that do not work. I will have to relay the track again , minus the curves. Thanks a million for your help regards. 1 Quote Link to comment Share on other sites More sharing options...
0 murrayec Posted March 2, 2019 Share Posted March 2, 2019 Hi joe123 Here is a thought- what about removing the two acute bends and have the return loop there! that may be an economical solution. Eoin Quote Link to comment Share on other sites More sharing options...
0 joe123 Posted March 2, 2019 Author Share Posted March 2, 2019 Yes I see what you mean. That makes perfect sense. Could hide the loop with a building or something similar cheers 1 Quote Link to comment Share on other sites More sharing options...
