Micrometer Holder

[BaronJ]

Hi Guys,

I hope that this is the right place to post my "Micrometer Holder" thread and pictures.

This picture is of the three parts cut so far. This also shows how the wings will be mounted. They were cut from a 95 mm diameter by 10 mm thick steel disc, retrieved from the scrap bin. I used the M6 threaded hole in the middle to mount the disc on a mandrel, in order to face it and remove the flame cut edge.

The two 20 mm wide wings were cut using a bandsaw from the disc. I also cut the top flat edge off to remove the laser start hole. All the other holes and groove were already in the piece when I got it.

When the other edge is removed the base will be 75 mm in length.

Each wing is 20 mm wide. These will be trimmed lengthwise to match the base.

I will be doing a drawing at a later date when I have figured out some sizes.

A couple of drawings !

The base drawing blue dots are 4 mm diameter pilot holes used to mark the hole positions in the wings. They will later be opened out to M5 clearance. Material thickness is 12 mm.

The blue holes are drilled 4 mm to a maximum depth of 15 mm then threaded M5 . The wings are the off cuts from the base disk. Nominally 75 mm long and 20 mm high.
