I have the plans for a die wrench and for a machinest jack, I know the
wrench had milling on it can't recal if the jack did or not. Also im
making a floating reamer holder at the moment. Have to think about some
of the other plans I have, I am in an intermidiate/begineer machining
class at the moment. I have a schematic for a hammer but as others have
said it seems like a boring/pointless project concidering you can go
buy one anywhere.

In my beliefe if your going to take the time to make it it better be
something worth that time involved, thats one reason why im not to fond
of my machining classes however there are some good projects.

For example in my machining 1 class we made, 2 sets of bolts 1 single
point threaded 1 die threaded, a set of parelell bars a set of 1-2-3
blocks and I don't even recall what else if there was anything else.
But none of it was worth making in my book. Yes I learned how to use
the machines etc but still I think there could have been better
projects that were actualy usefull that would have tought the same
things.

Example like about for a threading project practice threading a
paintball barrel on roundstock then eather making a paintball barrel
getting real cheep ones or whatever and threading them then letting the
students make custom fake muzzle breaks/flash hiders/silencers etc,
even if they didnt have a paintball gun if you did it to a spec that
some painball guns already use for muzzle break threads they could sell
there projects to others. The real reason I bring this up is a guy in
my machining class was making a barrel for his paintball gun and
another student was milling off parts of his and re contouring it to
make it look better. Its not just a good idea they do this stuff
anyhow.

Of course at my school we make the muzzle breaks/flash hiders for real
guns but most colleges don't have a gunsmithing department "talk
about fun machining projects" make a .50 bmg action put a barrel on it
then shoot it in the indoor rifle range.
