Get an A4 sheet of Baader solar filter material [aluminised Mylar] for ~£14 from Telescope House or other dealer. Make a tight fitting cell from card for the Baader filter to fit over the end of the scope. Check [without an eyepiece] there are no light leaks or pinholes in or around the filter before inserting eyepiece. Cap the finder - use its shadow to aim scope at sun.

You don't necessarily need to the full 5" scope aperture [seeing is frequently poor in daytime] and could make a small off-axis Baader filtered aperture that's clear of the secondary obstruction - I've used an oval mask [long axis parallel to tube wall] in the past to increase the effective aperture slightly. Good luck and safe viewing. Solar pics via URL below.
