--- Quote from: dawesy on November 28, 2014, 02:56:42 AM ---Very nice. Good work. Just as a thought if you ever need to do another is seamless pipe. I used some sch10 316L when making an exhaust manifold. It's a bit more expensive but has no seam to worry about. --- End quote --- Thanks Lee. That's good to know. If I ever have to do another....... --- Quote from: vtsteam on November 29, 2014, 02:11:21 PM ---Nice work David! --- End quote --- Thanks Steve. It's good to see you back among us, again...... :thumbup: David D |

Time to tackle the cylinder head. From a piece of 8mm stainless plate, 100mm square. (Room for a spare. If it all goes pear shaped). :( It was at, (only), this point, I realised I am not as young as I would like to be........ Several rests, and the following day. It was free....... I usually knock the corners off, by friction turning. In my mini lathe....... No chance! :palm: So, I mounted it in the r/t. And milled it roughly, round......... Normal lathework followed. Finally finishing the o/d between blocks....... The new head fits as a cap, over the cylinder flange. Giving .150" extra headroom, for a thicker graphite piston crown...... Looks rather nice, like this. Seems a pity to go poking holes into it....... Twin port! Because the new shim blade, was occasionally sucked into the full width original port........ Inside....... Much shorter inlet passage. Less heat absorbed into the head. Mebbe........ Shouldn't rust in there, now........ Thanks for looking in! :thumbup: David D |
