All looking good Nick! :thumbup: When I wor a lad, they used to say...... By the time a turner/ fitter retires, there`s been enough bits knocked off to make another of `em! ::) Let`s be carefull out there...... Re your flywheel recess tool. I used this one. Didn`t have to disturb settings....... Forward rotation for rim area..... Reverse rotation for boss area...... David D |

Many moons ago I did an article on making recesses in a flywheel. Unfortunately the accompanying vid went pear shaped ages ago, but there is enough on the post to give you a good idea of how to do it and what the tool looked like. http://www.homemodelenginemachinist.com/index.php?topic=844.0 If you go to the middle of the post, there is another link that will take you to where it shows you how to make flywheels out of plate material. http://www.homemodelenginemachinist.com/index.php?topic=228.0 Bogs |

Thanks for the replies guys, appreciate it :mmr: hopefully I'll have something to show later on tonight! :ddb: The thumb has been aching a bit today, was deepish but at least it's only a cut! I took the plaster off this morning and it hasn't fused back together yet, started opening up so new one has been on all day, should be ok now. It's amazing how much harder things are without your right thumb though, so guess the only good things to take out of this are that I shouldn't do it again, and it's just a little reminder that you definintely can't afford to lose one. David D, I like that tool, it would save quite a lot of time. Bogs, looking at your tool, I'm not sure whether it would chatter on my lathe, probably not though, shouldn't do. Interesting about grinding tools, I often get colour into them and do hack a lot off, basically until it's too hot to hold so I'm doing it all wrong. I have started quenching in water but only when I can't hold it! Might try that tool profile on the other side tonight. My recess is only 1/16" deep though so I would probably just do it in about 4 cuts. Will be interesting. I still haven't decided whether to drill the holes in the flywheel yet. I was liking the look of it plain, but it's a bit more fancy with the holes and I was trying to jazz this one up a bit with the columns and, radii and bolts so maybe I should stick to my original plan ... hmm! It will probably make the flywheel function better taking more mass away from the centre getting the moment of inertia up too. Stew, I didn't think of loctiting it to the shaft, don't know why but I like to be able to take things to bits! That loctite that's been in the fridge at work is 648 which I think is the high strength stuff, had a look the other day and it's never been opened, will ask if I can have it! I was going to loctite the columns in and the bearing but I don't think the bearing needs it and I've just realised taking that out gives enough clearance to assemble the piston onto crank and into cylinder short of taking all the 8ba bolts out which is a PITA! Very fiddley to get back in when the piston rod is in the way! Nick ps if I can do a video, not sure how effective it'll be, I don't really have a good compressor, if it runs it'll probably run from the car tyre pump thing but that is dead noisy, will have to make some sort of adaptor too. |

That rocker of yours is coming on a treat - Very impressed with your engineering a block of wood idea. Have fun, safely. Hope the thumb ok now. Gerhard |

So, I went & did something else instead....... ::) It might be ok now, with the taper bearings installed. :thumbup: David D. |
