Hi guys. Never done this and just beginning to get things sorted out. Called a steel supply store today and he did not have the 16 ga or1/16 tubing as called for but had 14 ga. He said ther was not that much difference in size and would not be a problem. What is your take on that and would it be useable to go with the slightly larger size? I really would like to stick to the plans but I don't think there would be much difference at all not even in weight considering the amount that is used. What is your opinions on this. I will be watching for a response if you can. Thanks gphil

Personally, Gphil, I'd hate to use 14 gauge. It's pretty heavy.
Heck, the 16 gauge is heavy enough, if you ask me.
I've noticed that even a little 2 foot long piece of 14 feels noticeably heavier.

Thanks for the information and I will go looking elsewhere. I was trying to convience myself on the larger for I want to get going. In the back of my mind knew it would be a little heaver. One would think that here in Atlanta there would be loads of it. I am sure there is and I will ask the fella where I can get it. I did see some in the Home Depot store but it was too short. I will be watching. Still learning how to navigate this site. gphil

Hi Gphil and SirJoey,
Here is a chart I came across while looking for tubing.
http://tubularind.com/square.html

I faced the same problem with getting 16ga square tube.

The local supplier near me only had 14ga and up. They
charge by the pound for all they have, tubing, flat stock,
hardware, etc.. and a 12' length was $26. At the time the
price was $1 per pound. Based on the chart I linked above
a 12' length would be 25.968 lbs so that seems to be an
accurate weight. If I did the rest of my math correctly a
12' length of 2" x 2" 14ga tubing would be ~ 7.25 ounces
heavier per foot than 16ga which would be ~ 5lbs 4.4oz's
more for the full 12' length.

I will be using about 22' for my build so the frame will be
about 9lbs 10 ounces heavier due to the thicker wall tube.
That is not as heavy as I thought it would be. I do wonder
though, when I sit my butt down on this thing and put my
feet on the pedals to get it moving will I regret my choice?

I hope this helps...
Jay :builder2:

gphil - I have always been able to buy all the 16 ga tubing I want at this place. I haven't bought any in at least 6 months, but I would be surprised if they don't still have it.

They have some of the best prices in Atlanta too (about $1/pound last time I bought), and are hobbiest friendly and have no minimum order.

While it IS a bummer to have any unneccessary weight added, I wouldn't sweat it too much.

Consider this... if I'm out on a long ride on mine, & the batts go dead or the system fails for some reason,
(which already happened once with the CycleBully trailer, due to a faulty throttle wire),
I'll have 170 lbs in hub motor & batt weight alone to pedal home, PLUS the weight of the trike itself! :eek:

I figure the TOTAL weight of mine is gonna be around 250, thus the reason for my determination to have this thing geared low!
Hmmm... I wonder how that compares to the weight of a Moped? :thinking2:

Sir Joey - I can't speak for moped, but my buell blast (500cc) weighs about 360 pounds without me on it:

I used 14g on the Baby Wolf, but that's all I could find locally. I didn't want to pay shipping for this stuff also. I may try muffler pipe for one of these creations sometime...

Nice bike, TM! Disc brakes, love those mags, especially!
That sounds like a pretty light bike, considering it's a 500! Not bad!

Yeah being a one cylinder (They don't call em Thumpers for nothing) helps the weight if you can stand the low speed vibration lol. When Harley designed the engine (Buell is a subsidiary of Harley) they just took a Sportster engine and transmission and lopped off a cylinder. All the body panels in yellow are some kind of plastic, so they don't dent and weigh almost nothing. I love the 70 mpg though.

Ooops - don't want to hijack the thread. Back to 16 ga steel lol.

I had a 550-4 some years ago, which of course, is SMALL for a 4, but it was smooth as silk! :offtopic:

Its also a belt and pulley drive, and the engine is part of the frame (swing arm bolts to the engine/trans block) which saves some weight too. The fact that there is zero chain maintenance and the rest of its simplicity was what made me fall in love with it. Its just a big bicycle with a motor and really good brakes :scooter:. I haven't had her up beyond 75 mph, but my son got a ticket going 90 before he sold it to me and got a faster (and way smoother) 4 cylinder metric bike lol. I think that was pretty close to top end.

I managed to find a place close to me here in the Marietta area that has it , I think. This info was given to me from a welding shop locally. The place that wanted to sell me the 14 ga wanted 20.00 and a few cents for two 5ft. lengths. Seems to be in the ball park. I will get it nailed down and get going. Now I need to learn how to weld. I let you know what transpired real soon on the purchase. G

gp - if that doesn't work out for you, this place in Smyrna will sell you drops at good prices (good for practice) and will also sell you what you need and order for you. They also have pretty good prices and are very friendly. I have dealt with them before.

I have driven past that place probably a hundred times. Thanks if this other thing dosen't work out , I'll go there for sure. Thanks for the advice, trikeman, really appreciated. G
