    Calculating compression ratio...

    http://members.uia.net/pkelley2/DynamicCR.html Here is some interesting reading on compression ratio,s hopefully it explaines it better then I can. Cheers

    1915 Hudson kingpins needed - who would have these?

    the steel was 4140 ,then heat treat and grind. Cheers

    Calculating compression ratio...

    Batwing the more important factor is the valve timing.Compression ratio is the volume of the cylinder at bottom dead center to top dead center then squeezed into the combustion chamber.Right? But what about the valve timing are both valves closed when the piston starts upward on the compression stroke? No the intake valve depending on the engine will be still open so you must subtract the amount the piston moves upward from your stroke length.Example a 4 inch stroke of piston movement may only be 3. 3/4 of piston movement with both valves closed. This is tricky and difficult to find understand at first but a good head scratcher. Cheers

    Marty king pins are one of the easiest parts to make or repair. If you do not have the equipment get a machine shop to make them,depending on we're you live getting them heat treated before grinding can be a challenge. I made new ones for my 12 McIntyre and repaired the ones in my 06 Cadillac by having them hard chromed and ground to a size larger then the loosest bushing thereby keeping all original parts cheers

    Are the hobby members getting that old?

    I’m getting confused. Are the replacement parts for the cars, or for the owners who might need the services of the funeral home?

    How do I select a replacement spark plug?

    There are a couple of sparkplug vendors at Hershey by the stadium,and ebay buy them one at a time ,may take a couple of months. I have bought from Don McKinsey. Great guy 765-785-6284 has probably the most plugs of anybody around,tractor trailers full.

    How do I select a replacement spark plug?

    I like running old n.o.s. plugs form the era of the car.What I do is measure down the spark plug hole and measure what clearance I have in relation to the piston and valves in the open position and then get a plug that will put the electrode the deepest into the cylinder.I do not worry about heat ranges like in modern plugs because the compression ratio of older engines is not hot enough to cause worry.I don't even know when spark plug manufacturers started making different heat ranges for the same application.Also index the plug so the ground electrode is opposite or away from the combustion chamber--old drag race tip--but it works for more complete combustion. Hope this helps. Cheers Pete

    Help Me ID These Traction Bars

    46 woodie. If you were starting to make some good power and high rpm launches they did there job. However most were not installed properly as you alluded to.

    Help Me ID These Traction Bars

    These are after market bars for a leaf spring car. One end bolts under the spring to the two axle u bolts the other end the u bolt goes around the leafs toward the front so you can preload the bar. Most traction bars just had a rubber bumper at the front and was then hard to get a preload. FYI ladder bars were for cars with coil springs,traction for leaf springs

    Anyone need a small restoration project?

    I think it’s actually from Manchester according to the registration. It didn’t quite look like a London bus radiator

    Oil Leak Remedy Sought

    For the cleaning of aluminum oil pans etc. I have a 5 gallon bucket of carb cleaner(expensive but worth it) that I use and after cleaning paint/seal the inside with armature paint,works excellent. I would agree use the dye,diagnose the problem and repair as my old service manager used to say you can not repair what you don,t know is broke.. Cheers pete
  13. Also remember that the judging is a points system, not a first, second and third. Its a little complicated but if one car in your class totally knocks the socks off the judges, it means all the others in that class have to score well on the judging sheet to get any award. Similarly if the best car is a little worn, the bar is a little lower. So it could also be that all the cars in a class score a first or they all could get a third.

    Pre war cars insane prices

    I don't know how old your kids are but you need to be laying some groundwork so that they go Ooh and A ah and think dad getting some old weird car is the coolest thing. Take them round the Science and Tech museum in Ottawa, particularly on Open Doors Ottawa weekends that you get to go in the storage areas. Ask them what they would buy! You might be surprised by how enthused they get and it all helps your case when you finally find something that fits all your criteria. Good luck!
