Set up the correct angle on your rest (in this case 2.3 degrees) and grind against the vertical platen or disc. Keep it cool to avoid them coming adrift or warping.

When complete carefully remove from the block, sand off all glue and pin together as before. Sand the bevels and front edge using 220, 400, 800 and 1200 grit as shown and buff lightly to finish. The final sanding on the underside of the bolsters should now be done on a sharp 220 grit disc.

You can now completely finish the blade bevels and ricasso and tape it up, use a slow setting epoxy underneath the bolsters to prevent moisture penetration. Ensure your rivets are a good fit and rivet them down in sequence. Example: front-top, back-bottom, front-bottom and back-top. Go over this sequence a couple of times until they meet your approval - Don't Rush! - no clamping necessary.

NOTE: Shaped bolster can and do pose a problem in cutting the handle material to match; this can be alleviated if you work from a template.

Two Perspex templates are made - one of each side and located by drilling through a few rivet holes. Bevel the top front edge of each template as shown.

Paint the rear of the bolster and nearby tang area with Vaseline and fit the templates in place. Now using "Ceramic Clay" push this onto the bevelled template area and back of the bolster as shown, set aside to cure - use the next day.

NOTE: "Ceramic Clay" obtainable from most art shops, is similar to "Pratley's Putty" with the added benefit that it does not shrink as much when curing.
