Pedrag It would appear that constructing one's own hydrogen maser would be easier since purifying the hydrogen via a heated nickel or palladium leak is much simpler. Also the vacuum hardware is simpler and there is no need for a caesium detector etc. The biggest hurdle may be coating the storage bulb.
