Finding a replacement to fit that threaded insert if it isn’t a standard thread is going to be difficult. May be a case of drill out the insert and then fit a new m10 one so you can use an m10 dowel screw

Find out if you can take a sabbatical. If you can that’s a risk reduced way to give it a go. Otherwise I’d spend the evenings, weekends, holidays building skills, finding what you like making and then trying to build a market for them. When you know you can make x in y hours and sell for z...

What screws onto the threaded section? May be a case of get a 3/8 and see if it works.

The edges failing from carbide fall out is exactly why proper heat treatment is important, grain refining cycles, preheats, soaks at temp are all there to give uniformity and smaller carbides. The Ward doesn’t suffer from this as it won’t have the alloying elements forming carbides. The A2...

If you get desperate, the thin cutting discs in an angle grinder can be used to make the grooves, an angle grinder stand helps. A milling machine will be far easier and neater though! If I had one I’d offer

It’s funny knife forums think the people who do the plane tests are crazy and seemingly vice versa XHP is effectively a stainless D2. Being PM it’ll be finer than D2, but if hardness matters more than grain size, and rust resistance isn’t needed, why not just go for D2? Especially if you...

It’s probably industrial tool making that has funded the metallurgical research rather than knife making. Nearly all the heat treat specs talk about nominal thicknesses way above what would be used in knives. Yes there are some modern cutlery specific steels, but they aren’t what’s being...

This gives a quick overview- toasting or charring barrels isn’t for a smoky flavour, it’s to change the flavours coming from the oak or to add charcoal which will filter out some of the flavours from the spirit...

As you mention A2, with suitable heat treatment you can reduce the carbide size and give a decent performing steel. It’s extra steps in the process though, and so usually foregone. Unfortunately it’s ability to tolerate a wide range of temps in heat treating and tempering, and still give fairly...

52100 won’t really form chromium carbides as there’s not enough chromium in it, it’s just there to improve hardenability. and anyway cryo is a way of completing the phase transition from austenite to martensite. I wouldn’t say it’s popular for 52100 to be cryo’d, but it’s an experiment to see...

Toughness is different to hardness and often you trade one against the other, you can cryo 52100 to drop the RA to practically zero (and get a resultant increase in hardness) but as a result you get much less toughness, particularly at higher austenitising temps. 1095 and other low allowed...

Don’t forget the nut and fruit woods.

Commonly 52100 is referred to as bearing steel (it is a bearing steel) so would be a safe guess. Where it has different alloying to a more basic steel like O1, you can vary the outcome of heat treating a lot by the temperatures and times used during austenising. Kevin Cashen did a lot of...

I’m surprised by this as 1.5 thou is probably less than the amount steel moves due to the temperature difference between winter and summer. If I made sure my planes were always flatter than that, I’d have much less time for planing, if I ever got to that level of accuracy to start with.

On the one hand we complain that people won’t pay going rate for handmade furniture, and in the same breath criticise toolmakers for charging for their time in designing and making tools. A handmade table has little more functionality than an IKEA table. If people have the money and desire to...

When the whole thing is duck tape it somewhat diminishes the aesthetics jokes- so far no duck tape has been harmed in the name of secret Santa

Mine is testing my ability to make mistakes into features at the moment, two steps forward one step back! I hear how well you hide mistakes is a benchmark for a craftsman though

Trying to lap the sole by rubbing it back and forth on abrasive isn’t the way I’d go. If it was bad enough that it needed it just work on the toe and the heel separately checking often with a straight edge. Also, and this may not be the case here, but when jointing boards it’s really easy to...

I was happy to see it again, feels like every time I see it I notice something new
