--- Quote from: -steves- on November 14, 2011, 03:05:09 PM ---Yes I can buy the bar cheaper from Ebay, but cant get a small amount of the 3/16 x 3/8 anywhere other than Stuarts :( --- End quote --- Couldn't you just buy some bigger (cheap from ebay) bar & turn it down to size? Surely cheaper than buying scrag ends from Stuarts? And good turning practice too... If you don't already have a set of dial calipers (or digital - but dial is better, no batteries to go flat & you can read between the marks for extra accuracy) then a set is well worth getting; also, a 0-1" (or 0-25mm) micrometer would be a wise purchase too. I can't remember where you are, but if you're anywhere near Merseyside you're welcome to borrow mine in the interim. Nice looking engine BTW... I've not dared try one yet - it's all very well doing a monster project like that sump, but there's no real "10th mm" or "thou" accuracy needed on that, not like a tiny little engine... |

I have re-made the crank webs now am happy, more or less, with the result, as always, you look back and think, I could have dome that better, lol. I have a set of digital verniers, as well as a set of metric and a set of imperial micrometers, but to be fair, I am not 100% sure on how tight to clamp them to get the correct readings, so tend to stick to the digital verniers for now. I am sure I will work things out as I go along.... That sump is an amazing bit of work, very very well thought out :) If I can take on a set of castings as a first project then anyone can, though the running bit remains to be seen, lol, it just might need some tweaking, who knows :thumbup: I truely believe this little 10V is a brilliant learning curve on so many things, even though at times, those learning curves can be very steep as a first step....all is good :) |

On the very end of your micrometer's twist handle, there should be a smaller twisty bit which, when the anvils touch the work, should start clicking like a ratchet handle. That gives you a constant pressure, and - in theory at least - constant readings. One of my mikes is a bit on the stiff side, so the ratchet doesn't work as it should do. If you don't have the ratchet handle on yours, get 'em sold off on eBay & buy a set that do.... Calipers are great for rough & ready readings, but when you need to be certain down to that last 0.001" (or less), then you just can't beat a micrometer. I'm sure you'll get a runner out of this project, just don't give up until it's going! Easier said than done, I know... Cheers! Ade. |

Thanks Ade, they do indeed have those ratchet bis on, each set is a set of 4, roughly from 0 to 100mm and 0 to 4", I did wonder what they were for, they also came with some fixed length bits, which I guessed were for setting them up, but again, I had no idea how to do that or if they needed doing, I will have a play with them and see how I get on :) |

I think you are very good at following directions. Real nice build, love your write ups. :beer: Nelson Collar |
