I like this way of contact very modern. From 77 year old customer!!

Excellent video guys! Much better to narrate separately to the activity.

Great video - first time trying and worked very well. WARNING - make sure you drill a wide enough hole for the latch first time - enlarging it is a nightmare (note: you will need a wider bit than the dimensions of the latch - next time I'll drill a hole in a piece of scrap wood to test first)

Very concise, useful and informative video. Thanks.

A very clear and concise guide. A have a gripe though, that forstner bit looks like a 22mil not a 20, as the latch goes straight in, which it wont with a 20mil. Anyway with a forstner bit, you can make adjustments that you cannot with a spade drill.

Have always used a 25mm bit to drill out for the latch 20mm is way to small

Belting cordless that, it still makes noise when it stops after first countersink at 3:54 ;)

Hi. Is it common to use a forstner drill bit in a power tool rather than a drill press? I'd have normally used a spade drill. what are the benefits of the forstner bit, simply cleaner cut, or less chance of splitting?

How do you change a heavy duty spring to a light weight spring in a noisy latch please?

Good tutorial on the latch part, but the marking out and positioning of where the keep sits needs to be shown for those who have never done this before.

Is that definitely the correct size flat drill bit to drill out the latch? I can never get it right first time and always end up using a chisel in order to fit the latch properly.

[kinderkid]

good video only needed to no how to measure the latch to get a replacement

I wish they had this stuff in the US. The giant predrilled knobs are all ugly

Do not use 20mm drill!

It's small!
