Face grooving tools – how they’re different from radial grooving tools
The face grooving holder is very different from the radial grooving holder. In a radial grooving holder the support section under the insert is straight, while in a face grooving holder it is curved.

Without the curve the holder will not enter the groove at all, and will foul with it. Also, because of the curve, each face grooving holder will only work within a certain groove diameter range.

Gothic architecture – what is it ?
I keep coming across buildings in India that are a mix of architectural styles. CST (alias VT station) in Mumbai is an amalgam of Victorian Gothic + Traditional Indian architecture.

I wondered what characterized each of these styles, and decided to start my education with Gothic. I learnt that Gothic architecture was characterized by three things: the pointed arch, the ribbed vault and the flying buttress.

A vault is a ceiling that is an arch-shaped structure, built over large spaces.
The ribbed vault has a complex rib structure supporting the roof, unlike the more common barrel vault has a semi-circular roof. The ribbed vault allows far more complex architecture.
The buttress is a support structure built against a wall to support the wall. The wall tends to be pushed outwards because of the weight of the roof, and the buttress prevents this.
Unlike an ordinary buttress, a flying buttress does not support the whole wall. It transfers the load from the top of the wall to a vertial column and thence to the ground.
