Our next project in class tune a smoothing plane. We bought a No. 3 Stanley for Kristin at the Swap Meet and I bought a Stanley No. 4C on E-Bay.
My plane before tuning.
Step 1: Flatten Sole or pay a guy to do it
The sole of the plane before grinding.
We set up wet-dry paper on a granite plate and tested the soles.
Given the condition of our planes, we decided to take our teacher up on an offer to send the planes to his machinist friend who ground the soles and squared one cheek for $25. We are just running out of time for lapping.
Here are the planes after machining:
Step 2: Sharpen Iron
Just like sharpening a chisel.
Lap the face.
We set the honing guide for 25 degrees up and honed up to 8000 Grit
We ground camber (curve) into the blade. Both of them are aggressively cambered and we plan to regrind and home one to make it more subtle.
Step 3: Tune Chip Breaker
We ground the chip breaker so that it sits flat on the plane iron.
Smoothing the top of the chip breaker so that chips rise easily.
Step 4: Tune Frog and Bed
We removed the frog, taped the lateral adjustment and then ground the frog flat on a diamond plate.
We put a silicone carbonate powder in grease and then ground the frog against the bed to seat it properly.
Step 4: Assemble
Now I should say that I did lose the frog adjustment screw and tote nut to Kristin’s plane. A few days later and a new set arrived it in the mail. I left the dog house.
The planes cut like a dream.
Next time: Block Planes
