Vintage bicycle frame repair is one of the most costly repair expenses for people who purchase and restore vintage or antique bicycles. Repairing a bicycle frame is a very costly expense, especially with vintage bicycles where the primary goal is maintaining the original bicycle parts, especially the frame.
Steel Connected by Lug Nuts
Most vintage bicycles are made of steel with the parts connected by lug nuts as compared to welding, so if you're working with a vintage bicycle with a steel frame connected by lug nuts, bicycle frame repair is going to be a bit different.
If you have a steel frame on your vintage bicycle that has no dings, rust, paint chips, or bends, you're in luck. If the only frame problems you're experiencing are related to lug nuts that have come lose or fallen off, the repair of your vintage frame will be simple. All you need to do is tighten or adjust the original lug nuts, or fix the parts by purchasing new lug nuts. Simple and clean fix.
If you have a steel frame vintage bicycle with bends or cracks, your bicycle will probably have to undergo professional repair and welding.
First, the whole bicycle will have to be disassembled. Paint will also have to be removed. The parts will then be welded back together. The frame will then be submerged in a solution and aged in an aging room. The frame will then have to be checked for proper alignment making sure the process hasn't altered the dimensions of the frame. When the frame is welded and inspected, everything will be cleaned, painted, and put back together. It is a long and expensive process.
Tip: Always perform rust removal before repainting your bike.
Rust removal can involve tools as varied as heat, steel wool, anti-rust primer and sandpaper. Some of these tools can scratch or dissolve paint.
Make sure you always perform rust removal before repainting your bicycle frame. Otherwise, you might end up having to repaint the frame again which is a waste of time and money.
Since most vintage bicycles are made out of steel, the most common problem vintage restorers notice is rust. If your vintage bicycle has chipped or worn paint, rusting can be an issue.
For bicycle frame repairs involving rust, clean the frame, aggressively removing the rust. You can even use a wire brush to scrape off heavy deposits. Use sandpaper to remove any remaining bits of rust.
After all of the rust has been removed, protect your bicycle frame with anti-rust primer and repaint the bicycle. To prevent future rusting, take the bicycle apart occasionally. Lube everything and put it back together, make sure you put your bicycle away dry, prevent your bicycle from getting wet, and make sure the paint job on your bicycle has no chips or worn areas to prevent the steel from rusting.
