  1. I've got a '73 240 that needs a little work. Posted details to this WTB ad:
  2. Hey, I've got a 73 240z with a 2000 LS1 and T56. I've had this car since 2004 and I've just stopped working on it. At one time it ran and drove but it needs a bit of TLC to finish/put back on the road. Mods/Features: No EGR Valve. ECM edit to remove VATS and after CAT O2. 3"x2" 14Ga tubing from front sub-frame to rear sub-frame. Q45 3.54 Viscous LSD Machined aluminum mustache bar bought from someone on hybridz. Fancy heat treated/cryo'd half shafts bought from someone on Hybridz some number of years ago. Q45 CV joints on half shafts. POR 15'd Fuel Tank JTR narrowed radiator. New Willwood Clutch master cylinder. New adjustable brake proportioning valve. Last time I took it for a test drive around the neighborhood I clipped a brake line. Someone who owned the car before me had gutted the proportional valve so I lost all brakes. That was excited. There is a little brake line work left to be done. All the work I did was with the Cunifer brake line. Enough line to finish included. 4-wheel disc brakes Dual exhaust. Crush bent but pretty darn good. i put the car on a rotisserie and undercoated it. Sandblasted down to bare metal. The rear wheel fenders have been replaced before I bought the car. I tried painted base/clear. I did something not right because the clear is coming off. There is a touch of rust in about two places. I included a picture of the worst spot. Professionally redone front bumper. It's a work of art. Deleted rear bumper. New tach and speedo Overall the car is in great condition. Needs some work but I've got a baby on the way and I've not really touched the car in a few years. I calculated some number years ago that I have about $15-20k in materials in the car. I need someone who wants to finish it to take it. I'd like $8k for it but I'll negotiate.
  3. I would have been really angry when I figured out what was going on, but I was too thankful that no one got hurt and that no real damage was done. I suppose I shouldn't have assumed that the stock valve was working. Something learned. :/ Thanks for the reply, I wanted to be sure that the tying the front brakes direct to the master cylinder and putting one of the one-in/one-out proportioning valves in the rear line was the correct solution. I am pretty comfortable with the installation. have a good one. -Gabe
  4. I almost have my '73 project up and running. I was test driving around the subdivision and one of the lines rubbed up against a half-shaft and put a hole in it. As a result I lost all hydraulic braking (Three cheers for a working hand brake!). I knew that there had been some changes to the braking system, the front has a Toyota conversion and the rear has ZX disks, but I did not know they had gutted the proportioning valve. I have searched and looked through several threads trying to find a recommendation for a proportioning valve and haven't had much luck. This is just going to be a street driven car, so I don't need a racing set up, but losing brakes is something I don't want to do again. So, recommended set up? new master cylinder? proportioning valve? if a proportioning valve is the answer, one-in / one-out or two-in/two-out? What am I forgetting to ask? Many thanks, -Gabe
  5. In theory, there is no difference between theory and practice. But in practice there is.

  7. I'll go ahead and toss a +1 for the older guns. I found a nice Mauser '98 in a gun store on consignment that had been fully worked. It's a scout rifle and it seems the previouls owner was a big guy and it didn't fit him well. new everything, with a scope, chambered in .308. shoots like a dream.
  8. Currently I am working as a contractor on a DOE reservation completing construction/startup/testing of a depleated uraniumhexifloride reprocessing facility. It's about 40-60 field-office work. I think i would enjoy it more if i had been here from the start and if it was not located in southern OH. My last job I worked as a project engineer for manufacture of capital equipment for pharmaceudical clean utilities. I really enjoyed this job. I got to help develop solutions to help customers meet their needs, design the equipment, oversee the fabrication, resolve issues that arose from testing and help with onsite start up. say, anyone out there looking for a clean utilities process engineer? self promotion> The nice thing about mechanical engineering is that it is (IMHO of course) the broadest engineering discipline. In college my non ME friends complained that the F.E. (Fundamentals of Engineering) exam should be renamed the M.E. because only ME's had all of the topics covered by the test. Best of luck! -Gabe
  9. There are 10 kinds of people in the world: those that understand binary and those that don't.
  10. I dare say it would only roll if the center of gravity fell outside the outer support. else it would slide just the one with zero friction (btw, if you find zero friction let me know, we can make some money! ) Also, I find both the statisticians and table engineer jokes to be almost too true to be funny. almost
  11. Wouldn't that be the one with the lesser mu because mu is the coeffecient of friction? And to add my favorites ----------------------------- An engineer, a physicist, and a mathematician were on a train heading north, and had just crossed the border into Scotland. The engineer looked out of the window and said "Look! Scottish sheep are black!" The physicist said, "No, no. Some Scottish sheep are black." The mathematician looked irritated. "There is at least one field, containing at least one sheep, of which at least one side is black." ------------------------------ Q: How do you tell and extroverted engineer?

  12. I assume this boiler operates at greater than 15psi? if so, then it should have an ASME stamp. if it has an ASME stamp you cannot weld on it or you will void the stamp, your warranty, and be liable if it ever goes boom. the fact that the cast iron is really clean makes me think you have a corrosion issue. I think the cast iron is supposed to passivate into a black oxide layer. This should be checked out. formation of a pin hole after 12 years might mean that the boiler is corroding and thin. this could result in a boiler failture and that would not be good. I also don't think that $5K for installation sounds right unless there are inspections and such that goes along with it. Being a fired boiler i don't think that just any plumber can work on it. I would check with your state boiler inspectors to make sure that you are working with people legally able to work on boilers and what the rules are for reinspections if any. better to do your homework and not have someone hurt with a improperly repaired boiler. I suppose i rambled some, let me try to summerize 1) have someone qualified to inspect boilers check to insure you do not have a corrosion problem with your boiler that effects more than the cast part that is currently leaking. I would also check that this unit is designed to suppy hot water. mostly hot water boilers are closed loop to help curb corrosion and prevent the issue you are experincing. 2) check with the state to insure what inspections/qualifications are required to repair this boiler. if you don't it might mean redoing this if you ever try to sell the house. I would also ask the state if they have a list of persons/companies that are qualified to do this. 3) find someone that can perform the repair/replacement at a fair price. best of luck, -Gabe
  13. Ok, so a little looking about shows that Mobil uses some kind of silica based scale inhibitor, not the more common phosphate type. From the warnings that they put on their products i don't think mixing the Mobil product with a "normal" antifreeze is a great idea. This is not to say you could not drain the blue stuff and put normal antifreeze in it's place, it is just the mixing that is frowned upon. http://www.fioresebernardino.it/schedetecniche/Mobil%20Antifreeze%20Extra.pdf I could not find the blue stuff as a US product, only brittish. It also looks like this phosphate free stuff is more of a Europen thing. Again a warning about mixing your inhibitors. http://www.prestone.com/carcare/faq.php I would say for the volume you're talking about i'd go out with the blue and in with the green with a 50/50 mixture. be sure to dilute with distilled or Reverse osmosis water. hope this is a little helpful.
  14. the owners manual should have a coolant spec. maybe an ASTM test number or such. if it says ethylene based, then you cannot use the low tox stuff as it is proplyene based. a little disclaimer, i'm not a "bike guy" but I am an engineer that does design/build/startup for thermal systems of various sorts. if you can share a spec or a product you're looking to replace i'll give what advice i can.
  15. do they make small fire truck horns?
