    The Diving Peregrino

    It’s machined like a fine shotgun... a Purdy perhaps. It would pair well with such!

    Lawnmower blades

    Many of the mower blades that I have spark like pretty high carbon steel! I even have some brand new ones that spark test like pretty high carbon metals. I’d not hesitate to use them for utilitarian cutting tools. Clearly mine are different from what you have though. My new “Oregon” blades have really nice spark showers!
  3. The sparks look good, but... you need to compare with a known steel sample. It could be an old axle or some such thing.

    Old Chisel

    Thomas; Look up 2” roughing gouge on google. You’ll see near duplicates of that tool. I don’t turn anymore but I used to own a couple almost exactly like it. They are very useful for turning square to round or rough smoothing log or branch stock.

    Old Chisel

    The fact that it says cast steel would seem to make it pretty old. Others here will know more on that topic. I can speak to the shape. It appears to be a roughing gouge for wood turning. While there’s a chance that it could be useful for timber framing or bowl carving... I’d bet on it being intended as a turning tool. Similar ones are being made today... but they don’t use cast steel anymore.

    The vinegar treatment is not just to remove rust. It will actually sharpen the file teeth as it undercuts the tooth edges! I usually soak them for a day or two and use a nylon brush to clear gunk and bubbles two or three times during the process. I rinse them in a baking soda solution afterward and then clear water and dry very quickly with heat (not enough heat to affect the temper). I follow the drying IMMEDIATELY with WD 40 spray... to inhibit rust. Most dull or semi-dull files will cut like brand new ones after this treatment!

    It followed me home

    That is a raising hammer. It’s typical use is to make bowl or cup shapes in copper, steel or silver. That’s an unusually large one. Those tongs are light duty fire tongs. People used to use them to get a coal from the fire to light their pipes with.

    Wooden Handles

    You might want to get some persimmon wood. It is related to ebony and usually has dark heartwood and IME interesting figure. I’ve never seen it commercially available but local tree trimmers occasionally run into some. I personally love pecan wood! It’s in the hickory family and truly tough with beautiful colors and figures!

    Pferd files are excellent! They are currently one of the largest manufacturers... so... widely available. Grobet (Swiss) files are superb, though costly! Grobet does have many specialty styles available. For standard types of files I find the Pferd brand is difficult to match up to... especially if your budget is not very overfunded! if you’re not committed to all new files. You can often get good bargains at flea markets and antique shops. I’ve acquired many from such sources that were nearly as good as new after a day or two soaking in vinegar!

    Clam shell rapier guards!

    If it were my project, I’d probably use an old rotary mower blade for material. Most of mine (mostly from high end commercial mowers) are about 1095 or 1080... something like that. At 1/4” thick they’d be pretty heavy! I’d probably thin them to no more than 1/8”... by forging.

    Get a load of my new Grinder

    Hmm... much to consider in Latticino’s post! I find most of it in complete disagreement with my own experiences though. Let’s start with slack belt work. I vastly prefer slightly convex grinds to other types! I control the degree of convexity with pretty good precision by adjusting the pressure which I apply. My viewpoint is... “why grind a secondary or micro bevel, when I can do it all at once and have a smootherblade that slices more effectively?”. I do have a 10” contact wheel which is always available if I move off the slack belt area. I use this for heavy removal work but move to my slack belt for refining edges. BTW I usually use a bit more acute angle for my edges which allows the slightly convex bevels to present just the optimal angle right at the cutting edges! Now as to my buffer. I use my buffer as an integral part of my sharpening sequence. I remove the wire edges with my buffer and also polish the edges just enough... just enough to make them sharper and longer lasting than any other type of edge finish that I have tried! The one exception is to polish the edges with polishing stones to a mirrored surface. This takes days or even weeks... but the results are stunning! My buffed edges are very nearly as good with mere minutes invested! Because of the lower number of cutting edges, I find that for blade grinding, any grits beyond about 50 or 60 grit will actually slow my work significantly. If you do lots of grinding on annealed stock or mild steels you’ll find more use for coarser grits. All the work that coarser grits would do for me... I achieve by forging! I am really confident of this advice and use it regularly myself. If you disagree, well do it your own way... but here is gold if you want to pick it up! Joy of the forge to all of you! I’d buy a round if we were close enough!
  12. I have often experienced poor results from partial quenches. IMO you’d be better off doing a full quench and then drawing temper differentially. You might also consider a few normalizing cycles to address grain growth BEFORE heat treating. For beginners, grain growth is a common problem. They tend to heat too much and move the metal too slowly... a good recipe for excess grain growth. I agree with all the advice above re oil quenching too... it is my standard method. Water quenching can work well in certain situations... IMO it is best used by experienced smiths.

    Feeling Lost.

    I have to agree with JHCC, nails are useful and good practice. Tongs are kind of tricky work... lots of pretty good smiths are not comfortable making them. Handmade nails are not at all the same thing as what you can buy in the hardware stores... they can be vastly more useful. Hooks are also great projects to get you started. A good J hook is quite useful and an excellent skill builder!

    What did you do in the shop today?

    Vaughn; Sharpen your punch with a slight point on it... like a center punch with a pretty steep angle. The slight point helps to prevent sliding or skating off center. It won’t affect the punches function otherwise. I do like to finish up with a drill bit... just for efficiency sake, it’s faster. I do like to use a bob punch to create the countersink, which I sharpen as above and then it’s easier to just drill the through holes cold.

    The road to the workshop.

    I did not know that. Thanks!
