Remember my brother's hacked moped? ( http://sidecar.com/mbbs22/forums/thread-view.asp?tid=10827&posts=32&start=1 ). He fell in love with 3-wheels ride and didn't want to detach a sidecar when winter ended. Now he's getting a motorcycle drive license. What will be the best gift? Hacking his motorcycle, of course. This time, with passenger tub for brother's wife. Here the new project starts 🙂
Ingredients/skladniki/zutaten:
-one bike. Brother's Romet K125
-Wheel (18" cast aluminium, similar to bike's rear wheel, with the same brake model), damper, 15mm axle, thick-wall seamless pipe for swingarm, crown-type drill to cut pipes, swingarm bearings from Suzuki GN:
-Velorex 562 body
-whole crate of "other ingredients"
-some seamless pipes. 34mm, 3mm wall thickness, as in Junak 350 or Pannonia sidecar.
Two pipes are used but in excellent condition, they were cut form old coatrack (colleague's grandfather made almost everything heavy and war-proof). Almost no rust, when you compare it to new pipes that you can buy from locksmith/iron yard.
New, Izh inspired frame came into being this saturday:
Then I made a new swingarm. Caliper base is machined, to mount wheel as close to swingarm as possible. The closer, the better (shorter arm to brake/bend the axle):
Frame, swingarm, wheel, damper - everything put together.
Frame still without gussets. Front upper strut's eyebolt will be placed in thick, triangle-shaped gusset welded in place, where front tube meets bike-side tube. Welds between gusset and frame are much longer than between eyebolt socket and frame. And this will help to make better triangulation on this bike.
Keep the pictures and updates coming, always interesting to see new projects in the works, looking good so far.
I build stuff now and then, but not always so neat, kind of an old farmer cobbler. Last thing I built was a log skidder for my ATV, looks like a refugee from the scrap heap but works very well. I just don't have the patience to make things pretty, so I admire those who do.
Bear, if you could see my first rig, that I use until today... Looks like on picture, but after few (or few tens) mechanical experimepts and changes, with half lb of rust and mud on it, still being "tuned". Picture is 17 months old, so it's not very actual. But it's a base for its today condition.
My first rig built from scratch:
Brother's hack has to be usable and not look like scrap.
Masseltov Igor,
You beat me again with Your speed. Things improove in each new project.
Myself I never have been a friend of welding, as for I made for years a living with bedway scraping, where any heat source is the worst you can have.
With the 15mm axle I hope You got one from a Jawa or made it out of good crome molybden steel. A too soft chineese one with only one side supported I would not trust.
Best of all luck.
Sven
I love welding and I do it better and better. But it must be done really well, with good deep melt and few other "parameters". And with some redundancy. Weld is never such good as welded material itself. And you must be aware of heat bending. "Managing with heat bend, tips and tricks" could be separate, really fat book and a long (probably life long) course:)
Making a swingarm was an example of heat-bend fight. I welded few things to axle tube, with tack welds in proper places, against the place where arm is welded. Thanks to these stiffing things, my axle tube is straight sill. But I had to cut these things off after heat has radiated.
Fortunately, sidecar is non-symmetrical thing with many ways to set it up, so it can be as crooked as it only could be. So don't worry about heat bend. (JOKE, of course).
It's original Jawa axle. They had excellent parts. I bought a bunch of them. One works in brother's moped sidecar and is in excellent condition. "People say, that" the other option is to buy 10.9 grade screw and turn it.
"Massetlov"? Hmm, I don't recognize what it could mean.
looking forward to seeing more pictures. Looks very good.
This weekend I have discovered why my MIG welder doesn't always want do weld. The more people in my neighborhood comes for a weekend, the lower voltage available for me. This (sunny) weekend 205V instead of 220-230... MIGging (not glueing) anything thicker than 2mm impossible. Rain season has its pros. One of them is almost no people come. I can work with open doors, make noise, weld etc. And the daylight is almost shadeless in wet, non rainy hours.
I made few small things for the car. Rubber bushings for car's body:
Rubber bushing pads made of belt from old belt transporter, 12mm thick
And few engine guards for different bikes:
Another weekend, another works, and another hours taken for my private project. Results:
Suspension almost done. Upper mounting for damper not placed yet. Suspension bushings/sleeve bearings transplanted from Suzuki GN. But in GN they are placed in two separate, open slots. I have placed them in one tube, so I colud add greasing point.
Yesterday fabricated lower front mount (with 16mm heim joint, thick-wall seamless pipe) and front left body mount "in action":
Yeah, sidecar ready. Low-budget project but fully usable and mechanically correct. Only aesthetic suffers a lot from costs. 1150km done in one trip - 2 weeks with trekking periods - car attached temporarily to my bike, identical like a destination one. Works perfectly. Happy crew (me and Little Mi):

Now, thats darn nice lookin.
congratulations Igor,
my grandmother only learned little jiddish, polish and russian by hearing and speeking in former Königsberg/ now Kaliningrad
so what i understand as masseltof is jiddish for splendid/excellent.
grandma's sister in law Lene who is from Vilna/Vilnus has nearly never used polish since she had to flee using grandma's passport.
a polish woman married to a german would have had a hard time in 45. grandma stayed until 49 or so.
Aunt Lene is still going strong and the soul of the family.
