Push trailer help

I'm tryin to build a good push trailer. I am getting frustrated to say the least. i have managed to build a strong hitch point on the bike, and a trailer i could easily mount the motor on. I am unhappy with the way the trailer is towing. i used a single wheel hoping the trailer would lean with the bike during conering. that works but it does not turn well at low speeds.
Perhaps i should go to a two wheel trailer, or perhaps i can build a better hitch. I havent seen much on push trailers in the forums here, just enough that i wanted to try it too. I would like to ask those with working push trailers to post some pics, if you have any and dont mind sharing.

I was able to cure my towing problems. on to mounting my motor!!!!!

i'll take pics,i will have to read the thread on how to downsize em. i've tried before to upload pics on here but come to an error.

Pic one, still need a throttle hook up but pretty well everything else is ready.

Here is a better pic of the hitch, dont mind the unfinished look....lol. Pls dont confuse the steel legged table or the scrap pile in the background.

Well in this case i challenged myself to build from things i had around the yard as much as possible. The clutch, chain and rear sprocket are the only exceptions so far, and i will likely have to buy something to build my throttle cable. I was thinking to of a really long brake cable too. The other thing i wanted was no welds on the bike, a back yard bubble gummer like me has a hard enough job sticking like metals together, so a bolt on hitch was a requirment for me. The wheel is a 16 inch off a child's bike (sorry son), i was suprised it had beefier bearings and spoke's than an adults bike. I may well have to use something other than the 32 tooth sprocket for better low end.(was all they had in stock in this one horse town that day).. I have purchased others since then. my hitch incorperates a heavy duty hinge which will at my estimate , have to be replaced often. I originaaly had the hinge at arond 135 degrees but it didn't tow right at low speeds. By adding the trailer hitch tung and putting the swivelling hinge at 180 degrees greatly improved towing. Now that Canada day is over am hoping to get a cable for the throotle today. will keep you posted.

Oh one other deatil, in pic one you can see some shiny bolts holding thicker metal on opposing side of the motor, thats my ballast wiegt...as others did my motor is not centered, so i used counterweight to balance the one wheel set up. at top pedaling speed the trailer tows well and leans with the bike which is why i wanted a one wheel set up.

First test run went poorly. In fact poorly enough i may start all over. too much sway in my trailer made for a very hard to control bike. IF i do go any further with it i will post results.

My arm up to the bike is too light and or the trailer is too heavy. Im thinking about getting on to my next build though....this was an experiment and not meant to redefine push trailers as we now them now...lol. It was great practice building it, and thats what i want the most. I would like to build motorized bikes, and im learning more all the time.
Oh by the way im glad you like the bubble gummers comment, i guess it is a local thing....round here we always call a not so good welder a bubble gummer....
