ditto on the sharp bits, cobalt bits usually blaze through just about everything short of serious hardened steel, remember cobalts are a low speed bit and will burn out at average drill speeds, a cordless drill is about ideal, just watch for bit walk that it doesn't get out of hand and get your hole too off center to use with a helicoil.

on colds what i've found working for me the last couple years i alternate 2k mg of vitamin C and a couple multi vitamins in the mornings, C's one morning and multi's the next, since i've started doing that when i eventually do catch something i whip it's ass in short order, while everybody around me is dieing with the **** i just have the snots a couple days.

weather, supposed to hit 28 tonight and tomorrow night and 25 tuesday night, glad after a month with no heat the bastard finally came and fixed the heat pump, **** i hate heat pumps, especially this mongoloid air to ground weird bastard, next house i am building the system from scratch myself

Heat pumps suck....thermo heat pumps suck too....it's safe to say that all heat pumps suck.

Build a fire and burn something winfred...stay warm.

i've got 3 fire places and they all suck, literally, they exchange whatever heat that's in the house for smoke and a little radiant heat (another wonderful design, i don't think they got something right like flue size or the deflector plate or something), that's displaced by the cold air that gets in when you open the door for more wood, the one in the living room i made better with a snazzy set of doors a couple years ago but i still don't think it's worth the bother, mom seems to like it though

posting this weekend, but I'm sick and bored so i'm posting... I have a cabriolet waiting for me tomorrow though so i won't be around to bug anybody then.

Sorry to hear you are unwell Bill. Post away to your heart's content - always worth reading.

38F huh ?

I think what you need is a few weeks in Oz at the moment - 110F the other day and more sunshine than you can cope with !

We do have cars that need fixing here as well you know !

Bill don't feel bad it's officially 30 degrees here. I have a headcold (have for about a week now) and an ******* room mate who goes home on weekends, comes back and in the first 2 mins of getting in goes, "Its hot as **** in here..." and turns the A/C on. What he doesn't know, is that the best he'll get is "FAN" because I desoldered the switch for the compressor. If he weren't moving off campus in a week and a half, I'd have jumpered that A/C switch to ****ing heat.

huh? what's all this vita-veeta-vegemin nonsense people speak of. one of the completely unexpected side effects of going off of meat was that i don't get colds for longer than a day or two (or if its the two week flu, i just feel a little icky as opposed to vomiting my guts out like my friends or roomates). also, i can eat shiiite that would give normal people food poisoning and just get a 12 hour 'gastro' affliction

nice fiero, jeff (jealousy made me do it)

bill, your posts are always a good read... ive read dozens of them at a time

sounds like yours have, since grade 5 is usually not that bad to drill... then I would go with your second idea of a dremel but I use a dumore flex shaft instead that will take 1/4 inch shank carbide grinding ball mills. The dremel will have the same result ,it will just take a lot longer and a lot more patience. I think your right about it being electrolytically fused to the aluminum and you'll probably be grinding it out completely and helicoiling or tapping oversize

I bought cobalt bits and tried them--hardly make a dent. Then, tried diamond ball bits on my Dremel, with cutting fluid. That hardly makes a dent, either. So, I think the grade 5 steel in the sheared off bolt has hardened and fused with the aluminum intake manifold into which it was screwed.

Now, I'm wondering about two possibilities:

1. Use a plug-cutter type bit, sorta like but smaller than a hole saw used to cut holes in wood or steel doors to put the doorknob assembly in. Diamond hole saws are commonly sold on eBay, in various sizes, for cheap. A ~3/8" plug cutter bit would effectively use the 5/16" steel bolt shaft as a pilot, cutting the softer aluminum from around its circumference. Perhaps this cutting action could be supplemented by using an acid that eats up aluminum. (I forget what type of acid that I used once to dissolve aluminum that had fused onto a steel crankshaft from the alu. connecting rod on a seized lawnmower engine. It cleaned that fused alu. right off the crankshaft and left it looking brand new.) Anyway, the softer alu. has got to be a lot easier to cut than the hardened steel, and the alu. would have to be tapped out for helicoil installation.

2. Since electrolitic action apparently fused the alu. to the steel in the first place, could reverse current also reverse the process? In other words, is electroplating reversible? This steel bolt has been in the alu. manifold in close proximity to coolant water, for years. One theory holds that the combination is, in effect, a battery with electolisis. So, is that rapidly reversible?
