Perforated round metal plate (2"X1.25").
Perfect for maching gun jackets, exhaust covers, heater protective coverings, floor plates, etc.
To use this plate for cylindrical items, you first have to make some careful measurements: length is equal to the piece you need to cover; width should be three and a half times the diameter.
Next, find a needle or rod which is slightly smaller than the piece you need to cover and roll over the perforated plate.
Once you have the correct shape, glue the edges with CA glue.
Obviously for an application that is flat, you only need to cut the plate to the correct measurements.
This will add another level of realism to you modeling project.
