I have been experimenting with vinegar over the last few days. I'll start a new thread on it with a couple of pic's tomorrow. Is the magic Bog water anything similar John? |

I was looking at John's clips the other day and came across that elbow engine.. and I have to say.. I sat there with my mouth open all 10 times I watched it. :jaw: It is likely the coolest, crazy bizarre thing I have ever seen. I get it.... but WOW. I cant wait to see another one undertaken. I feel like a cave man seeing a I-Phone or something... |

Fly wheel:- I like the idea of a composite fly wheel with a brass rim and an ally hub. At the scrap yard I found a chunk of brass that looked about the right size to make two hubs, and whilst there I spotted a pile of scrap pistons, that looked just right for the hub. Rim The chunk of brass was trued up with a DTI in the big 6” four jaw chuck and the bore cleaned up, and a small stepped turned in it to locate the hub, the diameter was cleaned up and the rim parted off, it was then trued up again and the parted face cleaned up. At this point I realised that there was not enough metal to make two rims :hammer: OK I’ll have to look for something else for the second rim. Hub First job was to run a ruler over the piston to check if there was enough meat to do what I wanted, there was, so it was roughly trued up in the big four jaw, faced up and the diameter turned up oversize to the rim. It was then parted off in: this was done in stages using the tool to open out the grooves to give clearance at the sides to stop the tool getting fouled with swarf because it was such a deep part off. The pistons machined more like free machining mild steel forming nice chips, a small squirt of bog water improving the surface finish. That all for now got some domestic duties to attend to next posting in a couple of days. Cheers :wave: Stew |
