Has anyone lightened a TT frame? I'm tempted to install holes down the side rails.

Figured I would ask if anyone has already done this and if so - how did it play out?

Uh why? It is already very flexable and holes may allow cracks in stress areas. I don't see how 5 or 10 pounds of shavings from holes is going to help anything in the long term.
Now if we were trying to trim .0003 seconds off our time at the drag strip I could understand!:-)

I agree with Mack completely. The little weight removed is not worth the risk of cracks.

What are you trying to achieve?

If you're building a speedster with a TT frame, then driling it lighter would make sense. Not if you still have it as a truck :-)

Large diameter holes should take off a ton of weight. No drag strip just power/weight as usual!

Roger gets it - no one has done this before?

A speedster built with truck parts reminds me of a quote by Ettore Bugatti referring to Bentley racing cars: " Mr. Bentley builds the world's fastest trucks".

At risk of sounding like a smart ass, just how does one 'install' holes?

If your BMI is 25 or more, do something healthy and start with yourself. Not by drilling holes, however. :-)

Tim, if you would have an economical way of getting it, Im pretty sure there is a good size brass era car frame in a friends frame pile.It came out of my frame pile. No springs. Has sub frame to mount engine, originally had pan under engine. Forget what it is. In Indiana

Tim,

That is definitely VERY COOL speedster. However, from the look of it, weight was not a big consideration. :-)

Fire truck conversion?


Top of pagePrevious messageNext messageBottom of page Link to this message  By Henry Petrino in Modesto, CA on Friday, October 07, 2016 - 02:11 pm:

It looks like an American LaFrance Fire truck conversion, but I'm not certain.


Top of pagePrevious messageNext messageBottom of page Link to this message  By Jim Eviston on Friday, October 07, 2016 - 02:16 pm:

That's what I was thinking. I have mixed feelings about those. Provided a good complete fire truck was not destroyed no problem.

American LaFrance firetruck conversion in the pic - yes.

Jim, that is a very generous offer but as it stands now I only have TT wheels to work with. If I had a set of A wheels and tires all set to go I would be using T car running gear for the gearing / weight.

If I go with a car frame I will need to lengthen it and adding more than one foot to a car frame worries me.

If I use the truck running gear I still need to lengthen frame at least a foot (aux tranny).

All depends on what parts I can scrounge and I'm currently on a "barter only" budget per the Mrs.

I wouldn't drill lightening holes unless the frame is boxed or doubled.

One of Dad's friends in Saginaw Michigan years ago, Martin Tanner, built some very successful race cars. He drilled or cut round holes in EVERYTHING. It was before my time, but I have seen pictures of his cars, and he took it to the extreme. I would say on a lightweight speedster, you aren't risking anything. https://www.google.com/search?q=tanner+special+race+car&biw=1366&bih=638&source= lnms&tbm=isch&sa=X&ved=0ahUKEwi8v-PjwMnPAhXJ34MKHf23CM8Q_AUIBygC#tbm=isch&q=mart in+tanner+special+race+car&imgrc=GVZr6ezAQHTfCM%3A

A lot of race cars used modified TT frame rails. And TT axle shafts. Anybody interested, look up Delagrange Hisso. That car has TT axles.I have sat in that car on several occasions. Would not fit now.

Considering that TT rear wheels are made of near-unobtainium, you will likely be able to trade them for some car wheels and other stuff.
