« Part 1: And so it begins Part 2 of Infill plane construction series no next part

I finished making the vertical cuts for the dovetails in the sole plate. I clamped a piece of scrap wood cut at 75 degrees as a guide for my hacksaw blade. The guide block began to wear and lose accuracy after a couple cuts. At that point, I made enough guide blocks to use a fresh one for every cut.

Before removing the waste form the dovetails in the sole plate, I decided to open the mouth. It was easier to clamp the sole plate in the drill press vise with the sides still intact. I used a small diameter drill bit to perforate the perimeter of the mouth opening. I then drilled as much of the waste as possible without letting the bit wander. I tried to knock the remainder loose with a cold chisel, but it didn’t want to pop free. Now I’m left with the task of filing out the remainder of the waste.

After I clean out the mouth, I will then remove the waste from the tails in the sole plate.

thankĀ“s for the update :-)
and smart to cut the mouth now , most I have seen have cut the bottom plate over so they
easelyer can make the mouth when the peene the sides to the bottm plate

but its difficult on the first picture to see what and where the guide block is used and why—too close taken i think

on the second it seems to be a real big mouth but again that can be the picture that cheaten me

looking forward to the next instalment

take care

I think some of my holes wandered and the mouth was not as tight as I hoped. I also tried to punch the waste out with a cold chisel and it deformed some of the metal. I cut my losses and started a new plane. I got the mouth open and the bed angle is established. Then life got busy and I had to put the project down for now…
