I am looking for some times that you guys are running on a 32 ft best track. I am trying to get my car ready and want to make sure I am at least close. If some of you guys would be willing to share your times on a 32 ft track it would help me out a lot. If any of you guys are in Ohio and would want to meet up at my house or yours that would be cool too. Thanks

I just took off a section and made the pddr track a 32 footer... I just ran one of my pure stock cars and it ran a 2.483 ave 2.485's hope this helps...

Wow thanks for taking apart your track and doing that for me. Now I say wow again because I am way off the pace. I am only running around 2.577. My best ever run was 2.566. I do not know what else I could possibly do to gain a tenth. I have tuned and tuned on this car and several other I have built and can not find those times.
I am running 2.5 degree on the rears, 1.5 on the front, grooved BSA axles, lathe turned wheels, coned hubs, 4.99oz, 1/16 offset front, raised wheel, com is about 1inch, hob-e lube.
If you have any suggestions for me please feel free to let me know. I am stumped on what else I could do. I have two "stock" cars that have the Pro SS wheels and they do not even run that fast. They are only running 2.546 or so on my track.

I have not stopped sense i was 8 years old... welcome to pddr the fastest builders and cars around...

It takes me all day and then some. I'm going to get a block but I have to convince my wife that I really need it . Maybe if I tell her I could be helping out around the house more instead of in the basement all day she will let me get one.

I have not been bending my axles. I have in the past bent some out of frustration, but never to race.
I have been drilling my holes on a angle. I have been using my drill press. I have made fixtures for the drill press that allow me to drill at different degrees. These have been made of wood, but I know someone that is going to machine some out of aluminum.
I too was wondering if the difference is in the track or in the car. I have my track level and my starting gate is set so that as soon as the pin moves it activates my timer. It is so sensative that it does not alway reset the timer when the gate closes. If the gate travels at all the timer starts.
I ma looking forward to this racing season and my sons derby is Jan 17, so I wanted to make sure we are as fast as we can be by then with our pure stock cars.

You need to get THE BLOCK from Glenn & David, or MB4hire.com a no fail way to drill canted axle holes ;D

Mood, I have no questions about the block. I have watched the video many times and I am sure it is a great assest to many of the builders. How I am drilling my holes is very similair, but with my own jigs. I believe that my jigs are providing the same level of accuracy that the block provides. I may be wrong on that and if someone wants to loan me a block for testing I will be more then willing to state a product is better after testing. I am not willing to spend $80 to find out I am no better than I am already.

I bought a The Block and its the best investment for this hobby I've made yet. Last year for my son's pinewood race, we tried canting the rear axels...what a disaster! Now that I have The Block, I have drilled a couple blocks with canted rears and its amazingly simple to get the cars to run straight down a tuning board. After seeing the speeds of the builders at PDDR, I knew this tool is a must have...thank you Jewkes boys! And the help that everyone is willing to share is fantastic too.......(segue)......with that said, what is the best technique for bending the front axle for rail riding? How much bend do you give it? Any help would be great!

It is the little things that make the most difference. You should listen to Glenn when he tells you how to gain speed. There are little things along the way that he says are very important i.e. the deg of slope for track setup. I have a couple of cars that are faster than others on my 32 ft track but slower at pddr. I listened to Glenn's advice to check the slope and my track was set at 26.5. I adjusted it to 27.1 and it showed that the car that I thought should be the fastest, had a wiggle in it at that fast speed/slope. Made a small adjustment and... I also listened when Glenn told me to use the Block. I thought the same thing, how could that be any better than what I am doing now? Instead of over thinking it I called John and bought the Block . John unselfishly showed me how to use it, I built my first car and.... A friend of mine owns a McDonalds Franchise. I stopped by one afternoon and I found my friend washing the windows outside in the pouring down rain. I asked him "why are you washing the windows in the rain?". He said, "the book says if you want to make money wash the windows at this time of day rain or shine. I am making money so leave me alone". If Glenn wrote a book it would say buy the Block.

I can build 20 cars all the same, yet in some way there was somerthing a tad different. They all run differently. You might look at your axle prep and polish on the wheels also. I have been debating to send in a car also just to see how it compares for times. We run on a pentosi track here, 32 footer wooden, finish line at 29 feet. 2.16.20 is are fastest time. but it seems just with them taking it down and setting it up the next year. We have seen different times with a faster car. 2.17.60. you sound plenty fast to me. Aside I always like to add, everyone wants to win or be very fast. takes time, we still work on it. I've only been at it for 8 years. sporty If your cars run different it is not the wheel prep or axles prep... I think birel33 has the wheels and axle prep down... your cars run different because your alinment is not the same... I have watch your video on how you align cars.. sorry, I am not trying to be mean. but when i see cars fall to the floor it is hard for me to see how your alignment would be good... the alignment is the most important process in a fast car... you could have the best wheels and axles but if your alignment is out of wack then the wheels and axles mean Nothing... I think that most builders understand that they need there axles and wheels prepped and if they dont, the wheels and axles are available... the only thing left is alignment... and now that is taken care of, for anyone... ;D

I do not dought that some people are having a lot of luck using the Block. I am using a jig similiar to it. If someone is willing to loan me a Block as I am getting ready to build a few new cars I will be more then happy to try it. I have boxs of tools that people said would be great and save me time and money. They are not in my tool box, they are in cardboard boxes as they have not helped me. I just can not spend that kind of money without testing or putting my hands on one first. If someone is willing to loan me one for a few days and it works then I will be more then happy to purchase one and sing it praises.
I did manage to find some time on one of my cars today. I found .015 in it and it was my wife that said I should try something that worked. It was a design problem with my car that is why I am going to build some new ones. I think I can get the cars to 2.550 or so with the new design.
I have checked my slope on my track and it is around 27 degrees. So I do not think that is the problem.

Mine is also set at 27 deg. I just ran 2.484 with a 2.487 average. I sure it's not the Block though. I'm sure the alignment is no better than my other cars.
