Chainplate

The sequence shows the process used to make the carbon chainplate core from design specifications to final step.

After spending some hours trying to figure out an easy and efficient way to make this part I decided to use this simple jig based on a hard plastic sheet ( from a paint roller package) and two pieces of wood with holes for the G10 tube and an extra hole to pour the resin in.

At the end the part came out quite satisfactory needing only some minor sanding to take out some resin flashing.

After pouring the resin there was a small leak at the bottom which was readely blocked. There's a significant volume o resin involved and considerable temperature build up ocurred during curing which called for the use of a small fan to keep exotherm under control and avoid the distortion of the plastic sheet.

Tomorrow I'll aply the carbon laminate.
