It also said that drivers tend to drive their cars appropriately with regard to condition and age. In other words they compensate for condition and age. I wonder if reliance on a new car being safe is perhaps effecting the way people drive them in a bad way for the same reason. Mind you the Russians are a bit mad in any case! I agree with you about the Crab. I did some silly stuff in mine as a young bloke and it was always well behaved!
Just to clarify it didn't say all cars will necessarily perform well when rusty! Just the surprising result that some may stll perform well when rusty!
Certainly is an interesting subject. I had a look at a report from Monash Uni about the effects of roadworthy testing on safety. They had some interesting info in it. In one study it said your chances of surviving a crash even in a roadworthy vehicle 20+ years old are considerable worse just because new cars are so much better designed! It also said that a study which crash tested a rusty vehicle proved that the vehicle still performed well in the test. It did say that the vehicle did perform well when new, but suggested rusty dosen't necessarily suggest a death trap! In general though what I got out of it was if you want to maximize your chances of surviving on the road you nead a new car! Most cars of the landcrab era perform poorly even if they are roadworthy in comparison to modern vehicles!
Interesting to see your comments guys. Like I said QLD don't require testing. This is not age related it includes all vehicles. I have to add that the cops over here are not silly and have the power to put you off the road pending a roadworthy. Also you can't transfer registration without same. Seems to work just fine here! People who don't maintain their vehicles tend to have a vehicle that stands out somewhat and attract the law like flies! Mot as was when I was in the UK is no guarantee of a roadworthy vehicle! It even says that on the MOT from memory! Spend the money you save not having a test on you car, you wont miss the MOT!
You hit the nail on the head with the "heap" reference Chris. My dad coined the phrase "The Old Heap" for my UK car and it stuck. Hence the name 1800heap. It has faced the scrap yard many times since it has been in the family and has made it through just! My Dad bought it as a junker just for the tryes when I was 15 or so! That was the first scrapping close call 30+ years ago!
This is an interesting one. I live in Queensland where there is no annual check of vehicles. The requirements are for a road worthy only to sell a registered vehicle. The weather is good and we lack the salty roads of the uk which is a big factor in favour of the MOT. Having said that there are very few bombs on the road here surprisingly! I would say from the reaction on here already, most wouldn't want to drive a death trap, so you self regulate! A 40 year old car in the uk thats not a museum piece is getting looked after by someone. This person becomes very liable if the car crashes due to a roadworthy issue. Its a mad mechanic that dosen't let owners know of this kind of issue! Queensland do spot checks but this is rare. Even so it dosen't seem to be a problem here! Im for it I think given a similar set up.
Looks like your beer fridge should be well stocked after this lot Chris! Or is it a love job! Don't suppose you feel like moving to sunny Queensland and helping me with my crab! I am lacking inspiration at the moment and I have only done a little bit!
Thanks for the heads up about the oil thrower. I have managed to sort out the involute gear drawing I think yes. I am not happy with the pitch so I will probably change it. I have printed the new part and actually fitted it to the engine roughly. It just fits with a slightly modified tensioner. I am going to have to move the tensioner to improve the angles. There is a new problem I have noticed. One idler ends up close to the water pump so my plan for the timing cover will have to change!
Anyway here is a video clip which shows the operation. Not quite there but works more or less!
Thanks for the Moss links they were very interesting. Should help when the time comes.
I am almost ready to print version 5 of the assembly which should fit much better I think. I will shim the cam cog 0.05" to improve my clearance issue, then I think it will be ok. I will have to do the same with the crank gear obviously, so I hope that doesn't cause any unseen problems. The cam locating plate is part of my assemby so adding 0.05" to that is easy. I am just trying to get my head around how to CAD draw an involute gear properly for the mechanism. It takes about 7 hours to print the idler plate so I want to do a first try of the gear section on this print! Watching plenty of utube videos about it!
A useful tip that has helped me with many problems with difficult software is getting a program called "Team Viewer". It is free. You must have internet access on your laptop for it to work! What this allows is remote access to your laptop. You can then phone the supplier and get them to remote access the software and have a look for you! Marvelous as they can drive your laptop like they are sitting in front of it! You can watch them do it on the screen while you talk to them on the phone and tell them what you want. What happens is you open team viewer which then displays a number and an access pin. You give them both numbers and they are in. Most places we deal with support Team Viewer athough there are a couple of other versions that do the same thing.
