Ninety minutes of resurfacing work barely made one third of the lumber surface flat.

I made a straight cutting jig.
2020 Aluminium extrusion
M4x12 cap screw x3
M4 T nut x3
M3 Philips screw x3
40mm x 40mm, 2mm thickness of metal plate x3
40mm x 40mm, 5mm thickness of wooden plate x3
2040 Aluminium extrusion as the guide

Each plate has one M4 hole and one M3 hole.

Assembled jig


Attaching a lumber to the jig before the cut.
The aluminium extrusion provides straight line so that when the lumber cut through by the circular saw, the cut surface will have even surface.

Some twisted lumber even after its side is flat, when it’s being cut, it exerts uneven repelling force against the guide so that the cut pieces of lumber become uneven. So I came up with this idea of securing the lumber by the jig and C-clamp.

I processed six straight bars within an hour.

Drilled six M6 holes on the three bars

For cosmetic reason, I installed the bars underneath the top of workbench.

It had noticeable gap at the end of the bars.

This setup removed the gap between the bars and the top of workbench.

My first line of defense gears – safety glasses, earmuff – against injury. I personally recommend wearing safety glasses if possible whenever uses a power tool. I’ve encountered at least five incidents that probably could cause eye injury so far. Flying tiny debris is unpredictable.

Winter sucks. The workshop hasn’t have heat source yet. The old house manages temperature difference between ten to twelve degrees. Indoor temperature of the workshop is around fifteen degrees when the outdoor is close the freezing point.  I’ll have to carry extra weight over the body for good three months.
Work clothes:
Beanie, light work gloves, winter jacket, long sleeve, T-shirt, pants and long underwear pants, work boots.
