--- Quote from: Bernd on March 31, 2011, 11:42:16 AM ---Sorry to hear thar Doug. For a while ther I was wondering what 1/2 6-32 thread is. :palm: :doh: Then I realized reading further what you meant. :( Time for a little, what is it, alm or something of that sort to melt the tap out.? Bernd --- End quote --- It is a blind hole, so I can't even drive it through and build up the hole with weld and re-drill and tap... I tried to grind it out with a diamond tip dremel bit, worked some, but it was about a 1/2 inch of tap in the hole. I even tried to heat it up with the torch to soften it up then drill it out, HSS was still no match for it. It is one that is one the bottom and the other 3 will hold the cylinder tight, so I might just let it go this time. It's not worth rotating the cylinder 45 deg and drilling and tapping 8 new holes. :bang: I try to find my happy place.... :med: Doug |

--- Quote from: Da_Kengineer_Meister on March 31, 2011, 02:36:54 PM --- Probably better to find a small mold or tooling shop because a larger place like Atlanta EDM looks like the kind of place that is going to charge through the nose because your job is to small for them. Guess you could call and find out... --- End quote --- Its nice to have good friends like that with the tooling needed to do the job... Funny that you should say Atlanta EDM... I had them pulled up and was about to call... they were too busy to help little old me, and would probably charge a ton just to do this one hole, but did give me another place to go. Where this one is broken is not critical and not visual, it is on the bottom of the cylinder and there are 3 other bolts to hold the cylinder to the block plate. I think I will just fill the hole in the aluminum plate with alumiweld, re-drill smaller and tap the block plate, then put in a short dummy bolt to fill the hole. The only ones that will ever know it was like that are the ones reading this post... maybe I will rotate and re drill some day... I need to buy some better taps, I guess.... Doug |

I did some work on the V4 today.... two of the cam supports are drilled and shaped. Two more to go then I start working on the block and crank. The valves and cams will be done after the block, pistons, and connecting rods are done, in other words, after I figure out how I want to do them... and feel like working on all 16 of them for a REEEAAALLLYYY long time... More to come... Doug |

Made some progress on the V4 16V Quad OHC today... It's starting to look like something and not quite as huge as I thought it was going to be... still big, just not huge... The washers are an approximation of the size of the timing pulleys. They will be about 5/8 inch thick with a 3/8 hub turned down to about 3/4 inch. The flywheel is just roughed out... most of the middle will go away. Still designing the intake manifold. If I go with 4 carbs, it will be easier to build them (4) but a pain to sych them all up, so I think not... more to come... Doug |
