Madjack, Thanks for the tip - I honestly don't know why I didn't think of that. I was thinking of all sorts of stuff, making a custom boring bar with an offset drilled with packing (as I now know how to do that!) I didn't see the wood for the trees! I think I have a boring bar like that, just depends whether it's small enough, if not, I could use the one I made to fix the vice by chopping it off probably. Not sure about making the 2nd frame, it's taking ages! I know you're right though, if I drop onto 1 I'll end up with 1 engine and a nice box of bits that'll never get a frame to go with! Might take your advice then! Nick |

Nick, good going :clap: And very good close-up photos by the way; I struggled to comprehend the size you're working at, until you showed the drill for the 10BA - tapping drill size for me is 1.4mm and clearance 1.8mm, so that gave a bit of scale. You commented in my thread about machining marks - well, you are on the exact same level, or even better, with me from what I can see - nothing a bit of effort with files and emery won't clean up. One thing I did notice is your drilled holes - a smooth surface with a kind of "screw-thread" marking across it. That always puzzled me on my own work, until I realised I got that when I drilled through, and "quickly" removed the drill from the job. Try a test next time; when you bring the drill bit back out of the hole, do it as slowly as you fed it in ;) - but be prepared for a slightly over-sized hole. Build that second base as well :thumbup: - I'm sure you won't be sorry. Kind regards, Arnold |

Hi Arnold, thanks for the kind words and advice. I'll try that with the drill, I have a feeling you're right, I probably withdraw the drill too quickly. I should have mentioned something about scale, keep forgetting to include the coins in the pics. I was quite surprised when I realised I'd need to tap the pinch bolts 10ba. Never threaded anything this small before and it's deep in aluminium so I'll have to be careful. I got some ba bolts for Xmas but 8 was the smallest, never thought I'd need 10. I've found a couple of counter sunk head screws which will do if they are 10ba. So some bits are quite small on this engine but the bore is actually quite big at 11/16". No progress tonight but some good news for me ... I've got 1 of the broken cars back. I found a similar forum to this for Renault Clio Sports and a local enthusiast took the car away, took my engine out and put his in for an unbelievable price! He's doing a conversion on his. Chuffed to bits! Back onto this tomorrow, think I will do another frame and I've reconsidered about the base plate that goes under them, got an idea in mind for those. Nick |

Nick I think I've some 10ba you can have bought them because they were so small I though they were cute. :D Stew |
