MASKLESS TOUCH UP TOOL FOR SURFACE COATINGS
A maskless touch up tool having a faceplate and handle. The faceplate is placed on a surface for touching up of a coating on the surface. The surface may be on a rocket body. The faceplate may form a seal around a target region of the surface. The faceplate has an opening configured to receive a touch up coating therethrough for application of the touch up coating to the surface. The handle may extend away from the faceplate and be configured for gripping by a user. The tool may include a reservoir, or an attachment for an external container, configured to collect excess touch up coating from the surface. The tool may be used to touch up the surface coating without the need for masking of the surface.
1 . A tool for touching up a coating on a surface, the tool comprising:
a faceplate configured to be on a distal end of the tool and having an opening configured to surround a target region of the surface to receive the coating therethrough for application to the target region; and
a plurality of sidewalls extending proximally from the faceplate and at least partially forming a reservoir, the reservoir configured to receive excess of the coating from the target region.
2 . The tool of claim 1 further comprising a handle located proximally of the sidewalls.
3 . The tool of claim 1 further comprising a handle attached to one or more of the plurality of sidewalls by one or more support members.
4 . The tool of claim 3 , wherein the one or more support members comprise at least two support members arranged to connect at a proximal end of the tool and couple to the handle.
5 . The tool of claim 1 , wherein the plurality of sidewalls comprises two lateral sidewalls.
6 . The tool of claim 5 further comprising a runoff portion connected with the two lateral sidewalls.
7 . The tool of claim 1 , wherein the faceplate is configured to removably attach to the distal end of the tool.
8 . The tool of claim 1 , wherein the faceplate comprises a seal configured to form a sealing interface with at least part of the surface.
9 . The tool of claim 1 , wherein the faceplate comprises a distal side having a shape that matches a contour of the surface.
10 . The tool of claim 1 , wherein the faceplate comprises an additively manufactured material.
11 . The tool of claim 1 , wherein the faceplate is polygonal or rounded.
12 . A tool for touching up a coating on a surface, the tool comprising:
a distal end comprising a faceplate;
a proximal end comprising a handle;
one or more lateral sidewalls coupled with the faceplate and the handle; and
a runoff portion attached to the one or more lateral sidewalls, wherein the one or more lateral sidewalls and the runoff portion form a reservoir.
13 . The tool of claim 12 , wherein the one or more lateral sidewalls are coupled with the handle by one or more support members.
14 . The tool of claim 12 , wherein the one or more support members are curved.
15 . The tool of claim 12 further comprising a container configured to couple with the reservoir.
16 . The tool of claim 12 , wherein the runoff portion is configured to direct excess of the coating toward a centerline of the reservoir.
17 . The tool of claim 12 , wherein the one or more lateral sidewalls comprise two lateral sidewalls.
18 . The tool of claim 12 , wherein the faceplate is removably coupled with the one or more lateral sidewalls.
19 . The tool of claim 12 , wherein the faceplate comprises a seal.
20 . The tool of claim 12 , wherein the faceplate comprises a distal side configured to conform to a contour of the surface.
