Step 1: Think About Your Source Bike.

Feb 07,  · Finishing a old mini chopper build i started about a year ago.I hope you all enjoy!We also encourage and accept fun ideas and items from our fans that we can.

This is an instructable on how to build a chopper bike on a budget. The main inspiration for this came from AtomicZombie and Koolkat's instructables. I've recycled as many parts as possible, and used scrap materials when I could.

I took a 25 year old Raleigh Wisp ladies racing bike and converted it to something a bit out of the ordinary. These need to be quite heavy gauge as the forces involved will tend to bend the tubes. The diameter of this tubing should be either slightly smaller than the existing frame tubing to fit inside the cut tubes or slightly bigger to fit over the tubing.

Butt welding tubes of the same diameter is more difficult and will not be as strong unless your an expert welder and I'm not! I had some 1. Buy two cheap chains to join together. Read on for instructions on how I did it, and the mistakes I made along the way. Above all, enjoy building and don't give up! My sister's year-old Raleigh Wisp. I've wanted to build a chopper for a while, but surely we can't do anything with this Wisp, can we? It's an unusual frame - it's got twin top tubes which go from the steerer tube all the way down to the rear hub.

This is a really distinctive look and I wanted to keep it. I could use the twin top tubes as a nice place to mount the seat. OK, lets move on to the next stage - preparing the forks.

First thing - get the forks right. The look of the bike is defined by the forks. First things first: 1. Dismantle the front end of the bike - remove the handlebars, the stem, the headset and finally remove the forks.

Position the bike so that the headset is at a nice ride height. Don't worry about the angles at this stage. Make a measurement on how long the forks should be. I've measured the distance from the top of the headset to the front wheel's axle. It comes to about 4 feet! Wow, this is going to be a long bike. Next, I cut the steel pipe in half with an angle grinder. Stand the two pipes vertically and use the grinder on the ends so that they're exactly the same length.

Right now, our forks are just two tubes. There's no way of attaching them to a wheel, so we need to make some drop-outs. Pic 1 shows what we want to achieve. The drop-outs need to be strong. I used some scrap steel plate, about 3mm thick. This is ideal. Pic 2. Overlay one of the existing fork's drop-outs onto the steel to be cut.

This will give an indication of the size and shape of the piece to cut out. Use an angle grinder to cut out two pieces from the steel to form the drop-outs.

Pic 3. Angle grinding is never exact, so the drop-outs were not exactly the same. I aligned the drop-outs in a clamp and used the grinder to get their edges identical. Pic 4 Use the grinder to make the edges neat. Remember, the straighter the surface, the better the join will be. Pic 5. Clamp the two pieces together and cut out the slots for the wheel axle.

This way, you can be sure that when you use an angle grinder to cut the slots, both slots will be identical. Take your time here - don't cut too much of you'll risk the wheel popping out. Your aim here is to cut a slot just big enough for the wheel's axle to fit snugly. Keep trying to fit the wheel axle into the slots until they just fit.

A tight fit is needed - not a lose fit. Pic 6 Next, we need to weld the drop-outs to the forks. I used a magnetic mount to hold the drop-out to the fork. I only discovered this later during a test ride when a wheel's spokes were rubbing against the inner side of the fork tubes.

Luckily, I was able to use another wheel which fitted better, but take heed of this mistake! Pic 7. Tack weld the drop out to the forks. Check your alignment. When your happy that all is well, weld it securely.

Here's where the time taken to make a straight edge pays off! Ok, we have our two tubes and we've welded drop-outs onto them. My plan is to be able to bolt a steel plate to the tops of the forks, so we'll need to work out a way of being able to screw a bolt into the forks. Next step - make a threaded top for the forks. First of all, you'll need to get some nuts, bolts and washers. I bought a pack of M10 bolts, nuts and penny washers. All these are M10 size 10mm hole. These are really cheap from any hardware discount store.

Pic 1. Assemble a bolt, washer and nut as shown in the first picture. Weld each face of the nut to the washer. Remove the bolt, so you'll be left with a welded nut and washer as shown in the second picture. Now you should have a solid mount on the top of the forks This will enable us to screw a bolt into the forks. Let's move on. To recap - at this stage we have two tubes. Each tube has a drop-out on one end and a threaded nut at the other end.

Next step: Build the forks Cut the legs off the forks. Try and get the base at flat as possible. Using a bit of cardboard as a template, draw a semi circle around your new fork tubes. Use a marker to draw the shape of the new forks on the fork crown. Use an angle grinder to cut the shape of the new forks out of the crown.

Take your time here, try and get the shape as close as possible to the new forks. Attach the wheel to the ends of the forks. This will give use the correct width for the forks. If you've been careful, it should fit snugly. Using another bit of cardboard, mark and cut holes where the three tubes fit.

This will form the template which we'll use for the base plate and the top plate. Trim the cardboard so it's a nice neat shape. Make the base plate: Using the cardboard template, cut a shape from some sheet steel.

I used some scrap 1. Draw the two outer holes where the forks go onto the sheet steel. Use an angle grinder to cut the sheet steel so you have a base plate as shown in picture 3. Tack weld the base plate to the fork crown. Be careful not to get any weld spatter on the bearing races! Next we have to make a stem. If you like, you can cut the head off the existing stem.

I've chosen to make my own stem, as I had some steel pipe which fits inside the fork's steerer tube. Pic 4. Use the angle grinder to cut a 45 degree cut on the end of the tube. Cut the tube so that its length is correct for the steering bolt and wedge.
