Hello friends,Happy New Year for everybody.

At this time I would like to share an idea I had and made reality.

Sometimes we need to use our Forstener bits for European hinges and we are far from a good quality bench drill or the job doesn’t permit this use and we need to do the hole using a portable drill machine.

I made for use at hinge services but any size can be done and other Jobs wich controled deep is needed.

Works as precise as possible (not NASA tolerances of course) but precise because the stop works at rotative way and need do be equilibrate as a car wheel to avoid vibration.

I made the tool using a holesaw and a bench drill.Any wood scrap will work.I choose good quality wood because in Brazil I can find many at “garbage”.

First I made the round part using a holesaw.Ready for sand

A dowel give you back the wood for the next step

Using a 35 mm Forstener bit I made a hole deep enough to fit the entire height of bit

Change the position of dowel to do the next hole at back

This small hole fits the neck to lock the stop at bit shank.Use the dowel for centering perfect during glue time

Finished and ready to use

The carpet protect workpiece from scratches

You can use small bits too.In this case a 26 mm bit (very popular hinge size in Brazil)

Thanks for attention

Thanks for all comments.

If you need to make a many the best way to do it is using a PVC pipe redution.You need to choose only the better sizes for your necessity and insert a wood neck on center and is ready.

If you need to glue a carpet you can melt the PVC using a hot tray.

This PVC redution is easy to find in any country

This is a 40 mm bit.You can find the redution in many sizes

You need to glue or screw a wood neck here

A hot tray improve the área to glue a carpet if needed

Clean the leftovers

The wood neck fits nicely inside

You can cut way a piece of the neck to fit your necessity

Thanks for attention
