That's a real bummer mate, :Doh: but, as has been said, try the plug and redrill trick. :thumbup: |
| mklotz:
After you've plugged the existing hole, you might want to consider turning a steel rod the diameter of the required drill, putting a point on it, and using it as a center punch to mark the plug so the drill starts at that point. |

Right, bit of an update... Spent the weekend doing lots of things, but found little time for my engine, but time I did find... I managed to make the piston and the connecting rod to the crosshead, so that bits done and seems tight yet smooth. I also managed to make the main "bearings" or at least drill them out and machine them down to the correct size and bolt them in place, the good news was a bit of 9/32 bar rotated nicely in them so thats more good news. I had turn up in the post this morning my new valve chest and the new slide vavle, as I decided it was best to give it another go and see if I can make this right as I "think" I know what mistakes i made last time, I just hope I don't repeat any of them...lol. I also "hashed up the crankshaft, and i have my step father seeing if he can supply more heat to it and fix it, he said he will have to strip it apart and have another go. if all else fails then another order to Stuart models for some 9/32 steel bar and 2" of 3/16 x 3/8, hey ho......I reckon i should have just bought a complete spare engine at this rate, lol. 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 :( |

Well bit of an update but without any pics tonight... Progress so far.... Finished the cylinder off, I finally grew the necessary items to take on drilling the steam ways, and all went well, certainly better than expected. Also finished off the inlet and exhaust holes. Started the con rod, got the top end fitted to the cross head, got the pin made to join those and all is good there. Just got to do the bottom end of the con rod to do as and when the necessary parts grow sizeably enough. Same goes for the eccentric rod and cam. Still have the crank to finish off, though I have made all the parts, it just needs loctiting, drilling and pinning. After that, see if the thing runs I guess, then if it does, lots of cleaning up and tidying up. All going well, should be done by the end of the year (ish, give or take) Might post some pics up as and when I get the chance to..... |
