Making A four Flute mild duty Dovetail Cutter, by using Clickspring. The "unattainable Dovetail" undertaking requires a instead detailed narrow taper dovetail cutter. So on this video I make my possess from oil hardening (O1) tool metal. There's a lot of lathe and mill work in the mission, as good as hardening and tempering of the cutting device with normal shop gear. The "inconceivable Dovetail" undertaking will also be discovered right here: https://youtu.Be/a3V42KwLTeE if you want to support support the creation of those videos, then head on over to the Clickspring Patreon page: https://www.Patreon.Com/clickspring ask me A question: http://www.Clickspringprojects.Com/contact.Html comply with Clickspring: https://www.Patreon.Com/clickspring http://www.Facebook.Com/Clickspring1 http://plus.Google.Com/u/0/113668471124073837794/posts http://instagram.Com/clickspring1/ https://www.Tumblr.Com/blog/clickspring1 https://www.Pinterest.Com/clickspring1 Abbreviated Transcript: 00:06 one of the vital cutting instruments required to make this inconceivable dovetail puzzle is a slim taper dovetail cutter like this. It has an incorporated attitude of 22 degrees, and four teeth shaped via milling 4 straight flutes. 00:19 each and every teeth has constructive rake generated from the way in which the flutes are milled prior the centerline, And i'm going to grind in some alleviation angles at the back of every teeth after its been hardened. 00:30 step one was to turn the basic profile to form. And of direction i'll want something for the chuck hold onto after I start forming the tapered component of the cutter, so i am turning the profile for the shank first. 01:10 The slicing enamel have to be concentric with this shank, so i am taking away the three jaw chuck, and using an ER Collet chuck from here on, to provide a better effect. 01:33 there's quite a little bit of labor protruding from the collet, and its all supported through that slender shank, so somewhat of tailstock help will likely be needed to get an correct reduce. As soon as that aid used to be in situation, I fashioned the tapered profile of the cutter. 02:30 At this factor the workpiece is practically a cutter blank, ready to have some enamel formed, so your next step was to transfer it to the mill to cut the 4 flutes. 03:13 Now that most of the shaping of the cutter is complete, it can be taken to a purple warmth, quenched in oil to harden, and then slowly tempered it to a light straw colour. 03:30 Now ideally i would kind the remedy angles making use of a software cutter grinder, but I wouldn't have one, so i'm freehand grinding them utilizing this bench grinder. I am maintaining the contact with the wheel really quick to preserve the warmth generated to a minimal, I don't need the temperature to upward push a lot that it softens those slicing edges. 03:54 And at this factor the cutter is clearly complete, it just wishes to have the small burrs eliminated, and the slicing edges honed. And that i observed that its a especially easy cutter sharpen; it sits secure on the bench, and a small oilstone runs neatly down the flutes. 04:14 adequate, so with all edges honed and capable to reduce, provide it a run and see how it performs. I've used a usual end mill to take away the majority of the waste inventory from this experiment piece of aluminium, so that I put the bottom possible burden on the cutter. And for the most phase, it appears to perform particularly good. As continuously although, there are some barriers. 04:32 For one factor it cannot be run very rough. If the cutter heats up too much, the carbon steel will end up annealed, and instantly lose its cutting edge. Its a gentle duty cutter suitable to fairly soft substances. 04:forty four The velocity of the cut at the high of the software can also be much slower than on the backside, and the slicing geometry at the prime is not up to excellent too. So while the bottom is forming first-class chips, the top is a bit more inclined to rub the metallic as a substitute than cut it. 05:00 It wasn't a gigantic predicament, and a partial solution was once to take a completing cross on either aspect, as well as use some abrasive paper to knock down the burr, but nonetheless, it's now not ultimate. 05:08 And subsequently, it can be unlikely that the taper I shaped on the lathe has survived my freehand grinding of the relief angles, chiefly as I resharpen it. 05:sixteen The accuracy was first-rate for the project I used this cutter on, however I suppose its fair to say that freehand grinding of the relief limits the cutter to moderately low precision work like profiling and contouring. 05:28 Having stated all that, it cuts aluminium incredibly well, and looks like an inexpensive alternative for low volume, low precision work in softer materials, mainly if there's nothing available commercially.
