Hobelbank restoration #248

Open Duehok opened 2 years ago

Duehok commented 2 years ago

The older woodwork workbench has some issues that should be solvable and make it a lot more useable. Right now a wood piece cannot be held to saw it nor plane it, the bench has maybe 10% of its potential usefulness.

  1. Worn out vise jaws: the main vise only grips in the middle.
  2. Disformed dog holes. The dogs should fit in every one of the holes designed for them, it is not the case
  3. Falling dog/sticking dog. The dogs have a spring leaf that it supposed to hold them in place while still allowing them to be hidden
  4. WTF bolt. There is a big bolt sticking out exactly where the tail vise is and prevents it from closing.

Proposed solution to 1: Remove the vise and its jaw, flatten the jaw (router table? Planer? router + jig?) Cut out the corner of the bench, glue there a new piece of wood, plane it to be level with the rest of the bench.

Proposed solution to 2: Carefully chisel out the holes that need it

Proposed solution to 3: bend the spring leaves to a useable angle

Proposed solution to 4: First check why the F is that bolt there. If it is to repair a crack, replace the bolt with some epoxy in the crack. If it is to hold something, design a less ridiculously dumb solution.

The do-something day might be used to plan when and how to do all this.

Sounds great! The benchtop is also not flat, but that would be a bigger project I'm afraid - good idea to start with the workholding issues ;-)

Just make sure to double-check the dogs before changing any holes in the bench, please: I seem to remember there were two different kinds, and the thinner ones could fall through bigger holes? Maybe it was only differently bent springs though, it'll become obvious when they are all placed next to each other.

Some accessories may also be hidden in the drawer.

Good remark, I will measure both dogs'size(s).

Duehok commented 2 years ago

There are 4 dog holder. 2 have a shaft section of roughly 29x22 1 is 28x22 the last one is 26x22.

In the four holes of the tail vise, all dogs fit in the two outsides holes, none fit in the two inside holes.

Their springs are all different. My guess is that we have a set of two dog holders design to work together plus two other that have been orphaned and repurposed for this bench. PXL_20211015_185008262_2

Front vise: contrary to what I remembered, the bench is OK. The vise face will need some serious work. PXL_20211015_185145640

New problem: there is a very flimsy wood covering that protect the tail vise screw. It is broken. PXL_20211015_185835529_2
