  1. I should add some details about Dad's installation.  The Ruckstell was installed in the later axle with the bigger brakes.  The brake pedal is modified with linkage to operate the rear brakes.  I think the internal brake band was eliminated.  Of course there is also a foot throttle since the right hand can be rather busy.  Backing off the throttle was probably part of the ritual. 

  2. Motoringicons, you mention that you should back off the throttle and press the left pedal halfway.  Regrettably, it's been way too many years since I was in the driver's seat, but I recall Dad gave me different instructions.  The quickly/firmly motion rings familiar but the clutch motion is not.  I'm not sure about the throttle.  I was wondering the effects of shifting without using the clutch.  Background, after numerous other cars, mostly T's in the Thirties Dad installed the Ruckstel and a Warford in his 15 roadster and drove in up and down the East Coast.  He later installed this set up in his 24 hack which I drove a couple of times.  I still have both cars and expect to get back to them after retirement.  I'm looking for confirmation or "warning, don't do that", so that I'll have a better idea of how to drive it.  I'm most confident these units were salvaged back in the day and doubt highly he ever had them apart for repairs.  He just put a lot of miles on them.  I also wonder what type of oil I'll find in there.  Thanks

    my question- do these new cars burn out starters with the on and off?????????????

    Maybe some engineer will figure out that a starter isn't necessary.  With computer controlled ignition and then with a combustion chamber pressure sensor, or just the crankshaft positioning sensor any remaining intake charge could be ignited with some momentary timing change like manual advance cars could.  However, the fuel is typically shut off when throttle is closed.  

     

    Some golf carts shut down as soon as the go pedal is released and then run the starter when the go pedal is depressed again.  Well at least the Harley Davidson ones when I was caddying.

    I have a question about Rock Auto's warehouse system.

     I'll go online to buy the part I really need and find out what the freight is and what warehouse the part is coming from [warehouse A]. I will then order other parts I will need down the line always trying to stay with warehouse A [and trying not to raise my freight cost. I will then get to a point on my order where the next part I order will still be warehose A but the part I want will then be switched to warehouse B. I then have to cancel that last part and once again that original part goes back to being shipped from warehouse A. How does that happen and how do I get around it?

    I'm also a fairly regular Rock Auto customer and at times it seems like you can't win with the shipping.  At least now they let you know the warehouse differences.  It seems like once I'm done and send the order, I go duh, of course.  It really only matters when different parts can be put in the same box, which really only means small parts.  Many major components are shipped in their carton that sits on the shelf and they will not open it to put in an additional part you order.  The result is another shipping label and each one is costed by itself so different warehouse really doesn't matter.  It's really only the little parts that are shipped in another box or envelop and it you calculate the shipping with each item added, then you'll see which ones are free and which ones require another carton.  One short coming to online purchases is the shelf carton is not always a shipping carton and may not protect the item well enough during handling.  The manufacturers and distributors and still geared for traditional sales where a skid is sent and then broken down at point of sale and the customer carries it out of the store.  Don't even try to expect a discount item to be combined except with other discount items.  They must store them in a special out of the way warehouse.

  5. Naturally the driver for most people is some past affection for a particular vehicle.  Usually, the car one desires is  roughly their age.  Back in the Sixties when we we going to the local shows there were many early models and most of them had been restored to some level or another, usually not just a used car that was spruced up.  Here's my question since virtually all of those pioneers in the hobby are no longer with us, where are all those cars?  I can see some were sold and some were stashed in the back of the garage and may have been passed down a couple generations, but where are they?  Or has the hobby grown so much that only their representative percentage is lower and the absolute number is the same but tend to stay home since the later model travels better?  Or asked a different way would someone actually recycle grandpa's pride and joy because they can't find a buyer?  The good news about people aging and passing is the once pampered antique still exist and the price should adjust to the market demand.  Also the beauty of the very old vehicles as their tech gets older and older, the world of manufacturing technology continues to expand such that even some of the most obscure vehicles can have replacement parts made.  I think in the long run the early vintage vehicle will out live the highly tooled mass produced vehicles of the second half of the century.  

  6. My grandfather built a cutdown Model T for his family about that time. He had two daughters followed by four sons who were more than capable of doing it themselves. The youngest daughter would have turned 16 by 1921 and she would tell the story of driving it from PA to upstate NY in the winter, just once.

    Practically, it probably won't make any difference with the use of your car, but personally it would bother me every time I looked at it and realized that somewhere in its past a mistake was made and that I had done nothing to correct it.  Thankfully the Rudge wheels were installed correctly by the factory on my 300 SL and have worked perfectly for the 54 years I've had it.  They do take some "thumping" to loosen however.  M-B (Rudge) uses the more common variation where one strikes toward the front of the car to loosen and toward the rear to tighten.  Why Lotus pursued "a better idea" and reversed directions we'll leave to the devotees of that marque to argue. 

    Thanks ejboyd5 for those articles you posted earlier.  I just had a chance to scan through them and they confirm that the principle of the Hula Hoop is at play.  I didn't see mention of internal tapers on the knock offs.  Perhaps I missed it.  I was thinking that the same principle applies to the lug nuts as well as the wheel starts to squirm if the lugs are loose.

  8. No professional connection, just a mechanical engineer by birth and several trips around the Sun.  I just try to apply simple physics and a lot of observations to concepts.  I may not always get the complete set of details correct but do tend to look where others are not.   Still don't understand the logic behind left handed lugs nuts on the left side.  (Never tried to either)  As I recall the one time I had lug nuts tumbling in the hub cap it was on the right side with right hand threads.

    This is why knowing if the taper is an inner or outer is so important. Bob

     

    Why is everyone ignoring this very important difference in the knock off style?  British cars have an internal taper on the knock off while these wheels have an external taper on the knock off.  Under normal conditions there is no movement.  However, if the wheel loosens a bit, the wheel taper will on the knock off taper now there are two different diameters involved.  In one case the contact point is on the outside of the wheel hub and in one case it's on the inside.  This difference will generate rotation in different directions for each case.  The splines stop most of the movement but there will still be a tendency to revolve, but the weight of the car is to be transmitted through the tapers. 

     

    The confusing bit on the British hub is the inboard taper is external on the hub, but the loosening effect is on the knock off.

  10. Isn't the principle in play the one where a smaller diameter rotating inside a larger diameter has a net rotation in the opposite direction?  Then as Spinneyhill pointed out the direction depends on the style of locking taper and that is why you get two different answers.  Once you confirm internal or external taper, you will get consistent answers.  MG and Jaguar are external.

     

    Sorry it was 1937hd45.
