Ned Posted June 2, 2012 Author Share Posted June 2, 2012 Hey guys. Had a super productive day today! The whole thing has been pulled apart over the last little while and the loctite really didn't make things easy for me haha! i highly doubt those shafts would ever have come loose under normal operation! Anyway, modified the 2 plates to have the motors mounted as opposed motors rather than offset a bit. This way i can put 1 shaft between 2 motors to have a bearing on either side of the shafts. Need to find me a 35mm hole saw for the bearings of the support shaft and the output shaft. Also used my lathe to make up 5 new shafts for the motors. Just need to go to Money Badger HQ tomorrow to use a lathe that is a little better than mine to drill some holed in the end so i can attach them to the motors. Even though everyone says "don't modify your flywheel" etc, i turned 4 out of 10 of them down on the lathe today and will do the rest tomorrow/monday. This was just to get rid of some of the fins that poke out from the mounting face as they will be in the way later. may cut off all the other fins all the way down as well at some point but thats too much effort for now. So progress is being made i'm not sure if i'll have it running before summit, but i sure am trying! Quote Link to comment Share on other sites More sharing options...
Ned Posted June 4, 2012 Author Share Posted June 4, 2012 Take 10 standard flywheels end result; and the new shafts holding the motors together Now i have to get a new sprocket tomorrow and put a 20mm hole in it to go on the new shafts. Then i'll go get a hole saw for the bearings tomorrow as well and then i may be able to try and start 2 of the motors together to try get one running backwards nicely. Once i have that done, i can do the same to the other 8 and have a running motor! maybe haha Quote Link to comment Share on other sites More sharing options...
felixx Posted June 4, 2012 Share Posted June 4, 2012 good work, the thought of this thing running is more exciting than just about anything I can imagine Quote Link to comment Share on other sites More sharing options...
KKtrips Posted June 4, 2012 Share Posted June 4, 2012 so 5 motors will run backwards? Quote Link to comment Share on other sites More sharing options...
Ned Posted June 4, 2012 Author Share Posted June 4, 2012 Yup. 5 will run backwards. I'll still weave the chain and those motor pairs are all setup to run 180deg out from each other. Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted June 4, 2012 Share Posted June 4, 2012 Wont the cranks port timing be out? (assuming these have the hollow crank with the hole in it that opens/closes under the carb) Quote Link to comment Share on other sites More sharing options...
Ned Posted June 4, 2012 Author Share Posted June 4, 2012 Crank ports? I have a reed valve for the carb intake Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted June 4, 2012 Share Posted June 4, 2012 OH ok.... so there is no port timing to think of at all in relation to the crank? The only one ive ever had in bits before was a model airplane engine so i'm learning. Quote Link to comment Share on other sites More sharing options...
bubblegoose Posted June 4, 2012 Share Posted June 4, 2012 you will however need to fix the ignition timing (as im sure was mentioned ages ago) i doubt slotting the coils will be enough so may i suggest available for those little pit bikes so im sure they will fit your fine choice of motor Quote Link to comment Share on other sites More sharing options...
Yowzer Posted June 4, 2012 Share Posted June 4, 2012 Or just file away at the current ones Quote Link to comment Share on other sites More sharing options...
Ned Posted June 4, 2012 Author Share Posted June 4, 2012 Those things look sweet ! Quote Link to comment Share on other sites More sharing options...
DodgySam Posted June 4, 2012 Share Posted June 4, 2012 what the hell are those things? Quote Link to comment Share on other sites More sharing options...
Ned Posted June 4, 2012 Author Share Posted June 4, 2012 Looks like a timing key that's offset to change the timing Quote Link to comment Share on other sites More sharing options...
drftnmaz Posted June 4, 2012 Share Posted June 4, 2012 what the hell are those things? offset dowel Quote Link to comment Share on other sites More sharing options...
DodgySam Posted June 4, 2012 Share Posted June 4, 2012 hrmmm... Quote Link to comment Share on other sites More sharing options...
Yowzer Posted June 4, 2012 Share Posted June 4, 2012 Yah, you take them out, file a mm of them, mash back in, 6 degree of timing advance for more revs etc. Or just get those ofset ones. Quote Link to comment Share on other sites More sharing options...
bubblegoose Posted June 4, 2012 Share Posted June 4, 2012 if you file them whats to stop shit moving? also they cost me around $2 each last time i got some (4 years ago) Quote Link to comment Share on other sites More sharing options...
Yowzer Posted June 4, 2012 Share Posted June 4, 2012 The combination of nut and taper. Quote Link to comment Share on other sites More sharing options...
bubblegoose Posted June 4, 2012 Share Posted June 4, 2012 6 degree of timing advance for more revs etc. Or just get those ofset ones. i was intending these be used to change the now ATDC ignition of the reversed engine to make sure errbody catches my drift/aids Quote Link to comment Share on other sites More sharing options...
Yowzer Posted June 4, 2012 Share Posted June 4, 2012 Yeah, I dunno if you'd get one with enough offset to do that. You'd be better off machining a new channel into the flywheel I'd think. Depends on how much advance they run. Biggest key I've seen is 12deg. Quote Link to comment Share on other sites More sharing options...
