There are a lot of Disston saws available on eBay, problem is you don’t know exactly how straight of a blade you are getting till you get it. I blelieve the D-8’s and D-12’s are good saws and you can usually find good deals if you look long enough. The #12 London Spring is their best saw, but you will be competing with the collectors, they get pricey. Here is a tip that may help find a bargain, in your search field, type in “Diston saw”, sometimes folks listing the items will make a typo and you can take advantage of that.
Thats a great trick Stephen, I will definitely use that.
Spent today making a new handle and front knob for the plane. Got a chunk of rosewood from the local wood store. Both the rear handle and knob are now soaking up some linseed oil. After a lot of chopping and shaping I now discovered that my home depot rasp and files are not so good. Will have to look for a decent set of rasps and files for shaping.
