Yes I do tend to get wide eyed and a bit nutty when I am working on old iron. When you know the number of Widell tap from memory you got it bad. It is a sad day when I know to call 1-80 and ask for Hank from memory. If you are going to work on such stuff, you had better have a lot of bastard taps too. Most steels also tend to snap off half way down the hole, from thermal shock. Regular bits tend to cam out or slip, because they are tapered, or just don't fit snug enough. I find M2 holds up better, to hillbilly brass hammering and twisting, when one end is fourty below and the other end is jammed tight in a brass seat that is in a red hot Marvel-Schebler TTX iron carb casting. I have a huge assortment of custom ground screwdriver bits for carb work. I have to get one of those EDM things for home use. Drill presses are for those too poor to have real 'hand' tools. Mistress Bridgeport punches such pretty holes, in such an easy manner. ![]() Rozen I use my Starrett pointy edge finder to find center, when possible. I use filtered bacon grease, cut with ethyl alcohol, when going into such territory. JimRozen is also most correct to always use cutting fluid. They are holed to my long shank center drills. I have a homebrew set of tapered brass plugs for finding the center of holes. Ridgid extractors include hardened centering plugs for the standard sizes. I get twitchy when I must use 'the force'. I keep a spray of freezer on the end and apply heat to the offending casting. They do not deform the bugger as bad as those tapered, or square things. You pound it in to the drilled hole and slip on the adapter. ![]() There is an adapter that slips on the extractor so you can crank on it with a hex wrench, or socket. Ridgid screw extractors (Ridge Tool in Elyria Ohio) are round cylinders with straight ridge 'teeth' running down the length of the barrel. For carb jets and screws I normally use the smoke wrench with freezer spray. On average,I rebuild five updraft carbs a week and my right hand is getting numb from bitch slapping Engineers that have no buisness near tools. I spend half of my life doing jobs like this. They also come with left hand drills and pilots for getting to the middle of the problem. The parallel Rigid screw extractors are a thousand times better. I also say to chuck those tapered 'ezy-outs'. It is also more likely to 'catch' the original threads. A plug tap will follow old threads better than a taper tap for these jobs. Since you say you have a thread above sticking up, the tap will just peel out the old screw threads from the aluminum. A solid carbide drill center is the cat's meow for making a center dimple. An end mill is sometimes needed to start the first drill true. When the ezy-out is gone drill the brass out with the size of drill that is for seventy-five percent the thread depth.
