Hi All,

While doing some milling yesterday I noticed that the X axis feed on my Beavermill VBRP was slipping intermittently. It would drive for about half a revolution then slip then drive again.

When I removed the feed gear box I found the following.

Attachment 371681

How it was feeding at all I don't know.

The gears are 20 and 24 tooth. I can't measure the small gear accurately due to the damage. The 24 tooth gear has a diameter of 1.3 inches.

Despite much googling, I am unsure of the specifications of these gears. I think they are 20DP and 14.5 degrees PA, but I am not sure.

I have been trying to find a company who may be able to supply the basic gears but have not found anyone listing 20DP.

Can anyone help me to identify these gears and maybe suggest a source for them. I am thinking that the best way to handle this repair might be to turn off the old teeth and bore out some new gears and heat shrink them on to the original blanks.

Alternatively I would be keen to buy a set of gear cutters and have a go at making them myself if anyone knows where they are available from.

Thanks for any help you can provide.
