Welders And Sheet Metal Engineers
Good preparation is the single most important factor when it comes to achieving first class paintwork results. Poor finishes are almost always caused by poor preparation.
Here’s what you can do to help us: -
Strip your motorcycle / car part down completely. Don’t leave items such as swinging arms and stands attached. You can leave attached if you dont have the equipemnt to remove, but we charge extra for removal!!
Remove all roller or needle bearings.
There are two reasons for this
1. Roller or needle bearings that are left in can be ruined by the garnet abrasive grit which we use during the shot blasting process.
2. The oil and grease in these types of bearings will run out over your new paintwork when it is heated in the oven stoving process.
All other non lubricated bearings can be left in.
Thoroughly flush out tanks and oil in frame type frames with petrol or white spirit until the fluid is clean. Allow to drain until dry. Leave all filler caps and plugs in place to prevent grit from entering during the shot blasting process.
Remove all small parts such as rubber grommets, plastic and nylon bushes. Most plastics will melt in the oven. Rubber is usually OK.
Most important is to degrease your frame and parts thoroughly. The presence of oil and grease can ruin the final paint finish during the high temperature stoving stage. You can leave degreasing to us – but we charge!!
Our next step is to blast clean everything back to bare material. Blast cleaning not only removes rust and old paint but it also removes surface contamination and keys the surface for the paint to hold. We use extremely fine grit for this process so that bearing surfaces and threads are not damaged. The grit we use is sharp enough to remove paint but not sharp enough to pit or remove underlying metal surfaces.
Once the blasting process has been completed we then carry out the masking work. This consists of fitting tapered rubber bungs into female threads and high temperature stoving tape to machined surfaces and male threads. We prefer customers to leave all masking work to us. There is no need to fit bolts to threads or blank frame head stocks.
Prior to masking, parts are inspected for damage and cracks etc, at this stage minor damage will be corrected by welding (often free of charge) but heavy problem areas will be referred back to the customer for their input. Stripped captive nuts can at this stage be replaced but only if you tell us which ones.
