If you only plan on doing a couple maggard is the way to go.
I restore quite a few for my personal collection so I buy in bulk
I buy washers from microfasteners size #0, you buy them in packs of 100 if you start restoring they go faster than you might think especially as you lose them on the floor I buy 1/16" rod from texas knife supply, if you buy several feet the shipping is not bad.
My local hobby shops ( RC / planes etc) sells brass rod for a buck . I got 6 ft for $2.79 . Packs of washers for one razor is $3.00 but even if you don't use them all and plan more restos Microfasteners sells 100 for around $4.00 or so. This gives me enough to do around 25 razors for around $8.00.
