- It sounds like you have a good idea what you are doing so...
-
- I routinely use a piece of 3/8" * 12" * 48" plate glass that I glue
- sandpaper strips (3M spray adhesive) end-to-end to get a 4' long perfectly
- flat surface. You could alos purchase the long roles of PSA paper sold for
- finishing sanders - I haven'y had a problem with either one. Do not use an
- abrasive directly on the glass because it will wear the glass too.
-
- 1) On metal soled planes, I use water-proof silicon carbide paper and
- plenty of water. Remove everything from the plane before starting (handles,
- iron, etc). Pick an appropriate grit of paper, depending on how bad the
- sole. Do not push the plane down as you take long smooth strokes - the
- longer the better. Use a very light touch and a lot of patience. Look at
- the sole every 25 strokes or so. You will see the high and low spots
- clearly; the high spots look matted from the sanding. Do not change to a
- finer grit of sandpaper until the sole is flat (no hi and low spots are
- visible). Move to the next finer grit of paper and repeat. You will still
- be able to tell the difference between the previous grit and the finer one.
- Continue like this until you get to 600 grit. At this point I switch over
- to mineral oil for the final polishing. I have been able to true up some
- really bad soles this way. I use the plate glass instead of my jointer bed
- for these reasons:
- 1) plate glass is cheap, jointer beds are not
- 2) I can use water on plate glass
- 3) plate glass is plenty flat enough for this type of work
- 4) I don't get glue and sanding particles all over my jointer.
-
- To recap: use lots of water, do not push on the plane as you stroke, take
- the longest strokes possible, take your time.
-
- 2) On wood sole plane I use the same procedure but without the water and
- oil lubricants.
-
- 3) I have had plane soles machined but it was expensive ($30.00 for 24" 8
- years ago). The other problem is that machining will inevitably take off
- more metal than needed. This may not be a concern for modern (new) tools
- but it is for antiques.
