  1. S - Sinistra - as in Sinister for Left. Apparently Lefties are considered sinister in Italy. D- Destra is for Right hand thread You need one of each because the drag needs to act to tighten.
  2. Some Cole pics. In the second, the Cole is labeled No 5 in the center. They are 1913's. http://www.earlyaviators.com/ecolejj.htm
  3. A "double welt cord" would probably not close up as tight as the photos seem to indicate. On the top of the seatback it looks like one cord is significantly bigger than the other. Along the top edge of the arm, not so much, it looks like not as much difference in size.
  4. That doesn't look like ordinary "hidem" to me. Maybe more like a "double welt cord" like in this video. For reference -
  5. Well, the vehicle may not be a 1925, but the photo is, at least supposedly taken in 1925. Thank you.
  6. This is what my vehicle looks like under the hood, for the sake of disclosure or whatever other reason. You've never owned an Alfa have you Bernie? A 1967 is by no means an antique by any standard, but it has no power steering, power brakes, air conditioning or electronic fuel injection. Open touring and gives more road feel than any modern car. If I drive directly to the west, you know where I end up? Bodega Bay where the Alfred Hitchcock movie The Birds was filmed. Do you happen to know which car was featured in that film?
  7. Collecting a bunch of small non-refundable deposits to "hold it for inspection." Not the dumbest way to run a scam I suppose.
  8. My mother's '85 Buick V6 Regal had valve cover oil leaks. And I think she was charged $400 to have one replace, then shortly after paid $600 to have them both replaced. And no they are not easy to work on because all the air conditioning equipment is in the way. I tried to change the spark plugs on it, and a couple of those were practically impossible to get to. I thought, you can't be serious, I need to remove some air conditioning equipment to change spark plugs? So I'd say if the valve cover is leaking a little oil, maybe the best thing to do is ignore it. Get one of these to do spark plugs instead of a regular socket wrench and extension, because it can get around obstructions better.
  9. Have you compared an Imperial 5/16 inch Whitworth side by side with a M8-1.25, meaning 8 mm and 1.25 mm per thread ( pitch ) ? I've never seen a Whitworth, but 5/16 inch is about 8 mm so I am thinking they might be close. I just can't imagine why FIAT would mix metric with Imperial ?
  10. 1949 DODGE D-29, D-30 FLATHEAD SIX WATER DISTRIBUTION TUBE Water distribution tube for all the 1949 Dodge 6 cylinder engines. Wayfarer, Meadowbrook and Coronet. When these things go wrong bad things start happening, ie overheating water loss, etc. Pull the old one out the front of the block and slide this brand new reproduction in and your back in business. We have been making these for years and have sold a lot of them. Coated in Cosmolene for protection, which is why it looks ugly! Link - TUBE
  11. Lovely. View of Lake Gleason - Deltona, Florida
  12. That "fretting precession" sounds like the real reason lug nuts on the left had left-hand threads, not the Coriolis nonsense I mentioned earlier, haha.
  13. Yes there is no reason to care at this point since it's been figured out. But the point is when a wheel and the associated spinner is rotating as it is traveling down the road at a constant rpm, there is no net torque of one relative to the other. They both have angular momentum in the same direction. So there should be no tendency to either tighten or loosen regardless of whether the threads are left or right or which side of the car they are on. Constant rpm, angular momentum, they continue to rotate at the same rate and the spinner and wheel at the same rate. It is the rotational equivalent of the Newton's law, "A body in motion will tend to stay in motion." It is when you have either friction or angular acceleration that a torque of one relative to the other (spinner relative to wheel) can be developed. For instance if the brakes were slammed on locking the wheel, the wheel would stop rotating, but the spinner due to it's angular momentum would be inclined to want to continue rotating, and this tendency would put a torque on the spinner relative to the wheel, so it would tighten or loosen depending on the thread direction. Or if you hit the gas, spin the rear wheels, the spinner will want to stay stationary due to it's "rotational inertia", not rotate. So it will want to tighten or loosen depending on the thread direction. A body at rest tends to stay at rest. As anther example : if I try to loosen a tight crankshaft pulley nut with a ratchet and a socket, I will just turn the whole engine over as the nut, pulley, and crankshaft all turn. But if you hit the nut with an impact gun it will come off, because the rotational inertia of the crankshaft will not let respond to the high angular acceleration the impact gun can deliver, so you get a torque of one relative to the other, nut relative to crankshaft. No traveling down the road at a constant speed should not tend to tighten or loosen the spinner no matter which side or thread direction. Just trying to clarify the physics of it. And why lug nuts on the left side had left thread is very difficult to understand, truly understand the physics of. One needs to study and understand rotational dynamics, vectors, angular acceleration, the Coriolis effect and all that to truly understand where that came from. But in fact the Coriolis effect is so small that it doesn't much matter anyway, and using right hand threads on the left for lug nuts is OK.
  14. You're not understanding something there.
  15. That is a nice looking engine. No I did not notice you had it for sale. This one is for sale, 14,000 US Dollars. Not in my price range anyway. Car Fiat 501 1923 for sale.
  16. I was in Sears just now and a lady was exchanging "fire wrenches." They are giving replacement wrenches for all those scavenged from the burned properties. Not surprising they are on the road to bankruptcy. I wonder if you took those to Lowes would they exchange them? Probably so?
  17. I just bought a set of wrenches for $20.45, 50% off. I'll see if they say made in USA when I pick them up. The set includes 11 wrenches in 8, 9, 10, 11, 12, 13, 14, 15, 17, 18 and 19mm.
  18. My local pawn shop has a ton of craftsman. $1 each or less. 5 wrenches or sockets for $3. Build yourself a complete set by searching through the bin and organizing.
  19. Sears was a place i could get a 32mm socket and a 36mm socket. These are used for crankshaft pulley nuts. And 22mm socket and wrench, which happens to be the same as 7/8 inch so you don't really need 22mm if you already have 7/8. And a 17mm and 14mm allen wrenches for transmission drain plugs. And you could buy a 15mm wrench if you somehow lost the one from your "set." A wide selection of individual tools, so it you need something including something out of the ordinary you could get it. Now Lowes just wants to sell the small sets, sockets and wrenches 8mm-17mm and that's it.
  20. So you put a right-hand thread knock-off hub on the right front side. Hmmm... under ordinary circumstances that should stay put anyway, even though it is wrong. At least we're thinking that is wrong at this point.
  21. You can't confuse lug nuts with knock-offs because the physics is different. Yes, for lug nuts the left side uses left hand threads. But that is because of the "Coriolis effect" or force, which does not apply in the knock-off case. The reason the Coriolis force comes into play with lug nuts is that the center of mass of the lug nut is some distance (radius) away from the axle which is the axis of rotation. That is not the case for the knock-off, where the center of the knock-off and the axle axis of rotation coincide. Left hand threads for the right side knock-off makes sense, because if you think of a moving car scraping against say a wall the friction force would tend to tighten it, the friction would be in the opposite direction of wheel rotation, so if the threads on the right side were left hand that would tighten it. In other words I think they chose the thread direction so that an accidental impact with a stationary object would be more likely to tighten it, not knock it loose.
  22. Looks like an eccentric mechanism that levers down. Interesting mechanism.
  23. So there were different types, and Dean Martin had a "humptrunk."
