Cutting my first gear

Here's a few pics of the spring loaded plunger on my VDH. It's just a stepped spindle with a spring inside that body that screws into the pice of flat bar bolted to the existing index plate holding bracket.Easy to make without drawings.

I made this non-standard right-angle mounting for the plunger so it can engage with the outside teeth on the 60T gear, which allows you to index more numbers, including fives and tens etc.

I did what you said…. Not perfect, but works!

If it will help to keep the chuck tight on the spindle, rotating the blank for the next tooth in the direction that tightens the chuck, to take out any backlash, MAY help.

It is taken as read that everything else is locked whilst the cut is being taken.

You are doing the right thing by experimenting and gaining experience on spare material, rather than on an expensive, or irreplaceable part! Fortunately, when I found the errors, the material could be replaced, so all in all, it was a useful learning curve.

Exactly Howard, this was a nice little thing to try with bits of scrap lying about, It didn’t cost a penny, unlike pretty much everything else I seem to do!
