Functional Test
- Prior to any work carried out, we will where possible make safe and carry out a functional test of your item.
Disassembly
- The necessary disassembly will be carried out and we sometimes take photos at certain stages for our gallery 'before and after'.
Cleaning/Degreasing
- We do a quick degrease with brake cleaner for metallic parts followed by two Acetone soaks. This is done to minimise contamination of our sandblaster as we only use expensive top quality aluminium oxide for our blasting. Sensitive parts such as plastics, polymers or carbon fiber are typically cleaned using a simple green mixture or IPA (Isopropyl Alcohol).
Partial Blasting
- As an example, for a barreled action we will blank/plug the chamber and the muzzle, then only blast the areas where there is likely to be trapped oil, in this case where the barrel is threaded into the action.
Gassing Out
- The gassing out process consists of heating the parts at curing temperature to force out trapped oils. This can be a lengthy and sometimes painful process as multiple heat cycles may be required.
Sandblasting
- In our case, aluminium oxide blasting. After successful gassing out and appropriate masking/blanking we will blast the whole part to achieve an etching surface that the coating will adhere to. We may use Scotchbrite to achieve an etching surface on some more sensitive materials.
Spraying
- Finally, before coating, clean, dry high pressure air is used to blow off any dust or residual media from the blasting process. Parts are then sprayed.
Cure
- Parts are then either left to ambient cure or baked to the appropriate temperature.
Reassembly
- Reassembly is then carried out and CLP applied where necessary. For barrels, an oily patch is run down the barrel. We will for the most part also apply the relevant Loctite to locations where it was noticed during disassembly, with the exception of scope base screws unless the customer explicitly requests this.
