A distressed looking man is walking towards the doors of the workshop, in his hands are two plastic shopping bags. We unpacked the bags and laid out the contents piece by piece on to the work bench. I started placing the jigsaw of a faring together, the shape it formed was that of a Honda CBR 600F side panel. On closer inspection it became more complicated, there were a number of pieces missing, some of these major.
I looked at him, he said “I was told it could not be done” I replied ” The only limiting factor is price” A smile crossed his face the first bit of good news in his quest to put his pride and joy back on the road. ” This is why we say bring it in let us see it in the flesh.” It was not a lost cause. After fixing the price, he left with a happier look, to return in a couple of weeks.
We had our work cut out, first thing to do was to fix all the bits together so the main part of the faring was in one piece, then we could start fabricating the missing parts, these would be cut from sheet plastic of the same material, if it is not the same type it will not weld together.
We are not like other repairers in that, we do not use two pack fillers to replace parts that are missing in thermoplastic products which a lot of faring’s are made from. Other repairers will do this were they can get away with it or say it cannot be done. If you have a vintage farings on your bike would you not want the best repair possible for this rare item? I know I would!
When you use the same material to repair a breakage it should act in the same way that it did before it was broken. If you introduce another part whether it’s filler or fiberglass it will change the way the panel acts and can cause the repair to fail in the future.
When the man returned he did not believe that it was the same panel until I showed him the back with it’s fine lines of weld. He was very pleased with the result.
Mister street fighter Alan (good friend) decides to put a Ducati 916 seat unit on his GSXR. I said “what’s that got to do with me?” “Well, I want you to turn the square back lights into round inset lights! Can you do it?” he said. “Of course, but you find the lights you want to fit!” “Deal.”
A few days later he turns up with the light housings. Now the work begins.
Turning the square holes into round ones was straight forward. Making the housing to mount the new lights on was not. It means weldingplastic mounts into the seat unit that would take a plate with the lights on and come out with ease once on the bike, not fouling on the frame.
It all went surprisingly well; Alan was over the moon when it was finished. The only reservations I had was the red paint work on a blue and white paint scheme. Turns out Alan had a problem too with the paint work because the next time I saw the bike it was black with polished metal work. Now it looked really sexy!
B.B’s attempt to ride the wings of the angel of the north ended in disaster today. It was his first try which he had nearly completed when there was a spine chilling loud creaking cracking noise as the wing he was riding on started to twist, followed by a snapping as the wing came away from the body of the angel.
Luckily the two spectators standing the closest to the the wing were pulled out of the way at the last minute by two of B.B’s support crew, as the edge of the wing hit the ground.
Emergency services were quick to arrive at the scene. Paramedics treated B.B at the scene before he was helicoptered to hospital. Suzanne and George Hackington were treated for shock, the two crew Sideways Jim and Melted Bert were also treated for minor injuries sustained in saving the Hackingtons from the falling wing.
The police and fire service are investigating how it was possible for the wing to come down. A spokes person for the council confirmed that an engineer had inspected the angel only two days before the stunt was to take place, giving the all clear for the attempt.
When asked a police spokes person said that they were keeping an open mind and would not be drawn on whether or not it had been sabotaged.
Dr Holingwood from the local hospital gave us a statement saying that Mr B.B Boots had had a miraculous escape stating that none of his injuries had been life threatening. He sustained a broken arm, fractured leg and a number of cuts with some heavy bruising. He is as comfortable as could be expected under the circumstances. It will be some time before he will be riding his bike again.
Mitch Dango event organiser said that they would cooperate with the investigation in any way they could and would like to thank and praise everyone involved for their quick responses. It could have ended very differently with several fatalities. He also said that he still cannot believe what had happened.
It is not that well-known among the wider biker community that we were the first to put a set of foxeyes ( head lights from a Honda fireblade) into a Suzuki GSXR 11oo nose cone. We were also the first to do it using sheet thermo plastic, molding it to fit an existing faring and welding these parts into place giving it durability and strength and above all that distinctive sexy look.

I only discovered recently that the nose cone was still about, in good condition and in one piece. But sadly not on the bike it was made for. It turns out that it is sitting on a shelf in someones garage looking for a new GSXR home.
I am pleased to say it has stood the test of time. Just go’s to show plastic welding is number one for repairs and custom work.
When considering whether or not a panel is worth repairing you need to take a number of things into account: Paint, decals, age and in some cases the foam backing.
Some manufacturers stick foam to the back of their side panels to stop the engine/frame
work rubbing against the back of the faring. It also stops any knocking noises and vibration while the bike is being ridden. When a panel sustains damage resulting in a crack or breakage or both, it does not always transfer to the foam behind. Even if it has not, the foam needs to be removed to do a repair. Where plastic welding is used the heat from the machine will melt the foam giving of a noxious gas. In most cases we can separate the foam in one piece from the plastic panel. So it can be reattached after the repair is compete, there by saving the cost of new foam for the customer.
There are some situations where it can not be removed in one piece. Foam, like plastic, deteriorates with age but at a faster rate. There are two types of foam backing – open cell and sealed. The former gets impregnated with road dirt, oil etc, this helps to degrade the backing more quickly turning it to dust, making it impossible to remove in some cases. Because the later is sealed it repels most of the detritus thrown up from the road and stops oil soaking into it. This increases the life of the foam, therefore making it a better candidate for removal when a repair is needed. The sealing helps to keep it in one piece making it easier to remove.
The pictures show.

We do from time to time get asked to repair plastic on bikes that are more than thirty years old. These panels present some unique challenges. Panels made of ABS, age, this leads to deterioration that shows it’s self in a couple of ways. The first are fishers appearing in the panel as you pass heat over the area to be repaired and secondly moisture leaching from these hair line cracks. It is well known that untreated ABS is hydroscopic.
Recently we had a gent in with two very old Triumph battery covers that had stress cracks. I say stress but to be honest these were signs of their age. The next indication was the way little rivers of water came running out of the plastic as heat was passed over the repair area, with numerous fishers opening as well. This complication turned a straight forward repair into a bit of a challenge.
It is difficult to know how far to to take repair’s like this. It was handy that the owner was in the workshop to experience what was happening. We agreed between us to only make good the cracks and some of the fishers that lead into those creaks. Otherwise the repair would have become very expensive.
We are often asked to repair plastic petrol tanks and motorcycle windscreens. In the case of the former we say no even though we have in the past repaired one. We only did it as an experiment to see if it could be done and the customer had spare tank material we could use to plug the holes. Did it work? As far as we know; we tested it with water in the workshop with no leak but petrol is another matter. We are happy to try another as a test to see if it works or not. BUT the material has to be identical to the tank you want repaired.
As for motorcycle windscreens we can repair them as long as they are made from Polycarbonate and the crack or piece broken off can not be seen when repaired. There is nowhere to hide with clear materials as you can see from the picture. Once repaired and prepared the plastic go’s a milky colour. Imagine how that would look running down the middle of your screen.
On a more serious note, in some cases broken screens are less expensive to replace than have repaired.
If you have been looking for our web site it no longer exists. It was a hard decision to make, we had become quite attached to the ageing site. To be honest it had been on life support for sometime, the number of patches it required to keep the ‘ailing body’ secure was taking up to much time.
So at the end of the month we allowed it to pass away…quietly! Now that it has gone we have more time to concentrate on the work we do. It just go’s to show what a lot of time was wasted on keeping it! We now have time to do the repairs,write and think what we would like to post on the blog again!
From what I understand, the only people that are really missing our presences are the scammers and hackers. They no longer have email addresses that they can fill with rubbish that wasted someone’s time to delete everyday! … it was no surprise that the person who looked after this side of things took all of us out for a drink to celebrate!
We were warned that it would impact the business big time, but as yet we have not seen a drop in sales, if anything the phones are ringing more. Life has become simpler and healthier.
So what next! a new web site? All in good time, you may see a new one. At the moment we are enjoying the freedom, it allows us to concentrate on our customers more. A big plus for our second to none service we already provide.
Don’t forget you can still get in touch on twitter @plasweld1 or you can find our founder Mitch on Facebook. We are happy to take questions on both sites. You will also find lots of images of the repairs we have done.
Even though plastic welding has been around since the seventies it is still surprising when a faring from that era comes in, how much fibre glass has been used to patch up the damaged areas. We were asked if it was possible to repair the plastic panel on a GSX 750 Katana the one with the pop up head light.
From what I have already said you would have gathered that these panels were in a bit of a state. Of all the farings that turned up it was the left and right side nose panels
( the nose cone in this case is divided into three section two sides and a Bezel that fitted around the pop up head light) that presented the biggest challenge. The customer wisely turned up with two panels for each side. The problem was to work out how much of each panel was the original plastic and which pair had the least fibre glass holding it together.
Fortunately the headlight bezel only had a cross shape lug missing. In itself not a difficult repair
but time consuming to reproduce. All the side panels were heavily damaged where the side mirrors would be mounted. One of which had a big bit missing.
The first thing that needed to be done was to get rid of the large quantity of fibre glass from the damaged areas.
Once it had been ground off the outside of the panel. The stuff caked over the inside was gently persuaded to leave home, coming away in one piece. Almost leaving it clean enough to weld. It just go’s to show if it had not been fibre glass both sides it would have fallen out ages ago.
The one thing plastic welding does not like is contamination of any kind. Which meant we had to remove as much of the residue as possible to be sure it would repair properly.
Once that was done new plastic was cut into shapes to replace all the missing bits. Because alot of the damage was concentrated in one place we had to be careful about over heating. By phasing the repair it would keep the heat shrink to a minimum, making for a better repair over all. You also have to take into account when renovating old plastic it has a tendency to get very brittle. A way round it is to temper the area with some heat before you start welding it together. This also helps to drive out any water that the plastic has soaked up over the years. This leads to a stronger weld and a satisfied customer.
Not all the plastic that turns up at our door can be repaired by gas welding. Dare I say it that we have to resort to two pack bonding don’t get me wrong it is a good repair but 90 seconds to apply the adhesive is not on some occasions enough time to get the job done.
