The one I have is called a fastlap TDM-1. Made by Peacock. It is made in japan. The company is Ozaki MFG, CO. LTD. The instructions are in japanesse, but you do not need them. Just remember that when you test your tires that you are a human checking these items. Some people get caught up it having different people opinion on the same tire and then say they are marked incorrect. What I use mine for is to be xonsistent within my own pits. I check a tire to see if one is harder than the other and so on. Not to see is it is the shore that is rated on the box. Hope this helps. If I can find a web site I will post it. And yes they are expensive, but not $500, more like $200.

Jaco uses the PTC Asker C type. I called PTC before I even posted.... yes $650 for a durometer.

How the heck would you order that TDM-1?? There's nothing on the website to order a durometer?

Looks like a pretty blue version of the MaxMod.

There is an order button on the top right (red box) - but don't use that. You might want to try RC Adviser Champ or ProShop Futaba .

I noticed a phone #. Maybe there is a contact us button. Try to e-mail them.

[QUOTE=fraz]I find this funny since Jaco has used nothing but color coded compounds until their fairly recent entry (couple years) into the nitro tire market. Where is Jack? What's the scoop, fill us in?

Color coding was the standard when we entered the electric tire business. Even Arrows used colors back in the day for their gas tires. Durometer readings eventually were adopted for gas only. Durometer readings create more confusion for the average racer than you can imagine. I get calls on a weekly basis asking about why we have two different tires that "read 35". I can give you 5 different tires that read 35, but if you put the 35 gas fronts on the rear and grays on the front, you won't get very far. Durometers are only good to compare tires in the same "family". Gas guys know that- everyone else doesn't. If you want to save money, get a cheap durometer and use it to compare your tires RELATIVE TO EACH OTHER. Don't use it to "verify" Brand X or Brand Y's accuracy in labeling. Make it your own personal gauge of how your tires compare. In this regard, a cheap one works as good as an expensive one.
When the factory grades the rubber they use a Type C Asker. This is a more common method for measuring in Japan. Over here, the American manufacturers use a Type 00. We obviously use the Type C or a similarly calibrated durometer since our industry has adopted these numbers as the standard.

We looked into having our own durometer made a few years back, but it was much too expensive. It really is insane what they get for these things. If you look inside there are only a few pieces. I suppose that since there isn't a huge market for durometers outside the rubber industry they need to make what they can on the few they sell.

This is a good article on how to use the durometer, is for big cars but it can help you out.

www.summitracing.com have durometrs for under $70. REMEMBER, we will use the durometres to check and fine tune our tires,


What I use mine for is to be xonsistent within my own pits. I check a tire to see if one is harder than the other and so on. Not to see is it is the shore that is rated on the box. Hope this helps. If I can find a web site I will post it. And yes they are expensive, but not $500, more like $200.
The scale that we need to use is A, base on this table and the pressure applied to the compound by the point or bit.

The max mod is like what , $80 or $90? Just get that.

garen 03-30-2007 07:35 AM

The Max Mod guy lives/lived in Arcadia, CA. I met him at his place about 5 years ago and he built one for me on the spot. I think he charged around $90 +/- a few $$. I can not remember his name or his phone number though. Maybe someone else knows him?

Superior Hobbies has the Max Mod Durometers in stock.....
