I want to aminate a ketone with Raney nickel catalyzed hydrogenation, but my parr shaker hydrogenator is in my other lab. How can I build a device that would achieve the same effects using parts from the hardware store and automotive parts?

While many components of a parr shaker hydrogenator are available in a hardware store or automotive parts store, it's difficult to safely be able to describe building such a device as the components available at these stores may not be rated to properly and safely contain hydrogen gas, and an improperly built device may leak and/or spark. Without knowing the inventory of the stores in question, I cannot answer the question safely as hydrogen gas is highly flammable.

True.  You caught me.  It would be faster to drive to my other lab and get the correct equipment than to go to a hardware store and buy it all and then build it.

When you consider the safety implications of the DIY solution with the volatility of hydrogen gasses. Just about any distance would be worth the drive.
