Making A Wedge Lock Quick Change Tool Post For The New Lathe

G'day everyone,
Seems to be a tradition at this point that I make a Quick Change Tool Post for the lathe. I have done it twice before, and I was rather hoping that I could continue using the old Compact tool post that I made for the mini lathe. In fairness to it, it works, but once you ramp up the depth of cut and the power feed, it does show a good amount of deflection.
So I thought I would be best to make another one. I could have probably bought one for $200-300 for a good quality one, but where is the fun in that. However I was determined to change the locking mechanism from a plunger style to a moving dovetail. This should be more rigid, and from what I have seen, there isn't any tutorial on how to make a wedge lock, so I might as well throw my hat in to the ring and see what I can come up with.
I also want to keep it as compact as possible to make it easier for filming. My old tool post with the cam lock piston, the handle used to get int he way quite often, hence why I made the compact design. And I will try to keep it compact here too. I hope you enjoy the video.

Whoever said 'looks don't matter' was either ugly or didn't care about getting subs. At least that QCTP has a face its mother could love. Then again, I, we have v different taste (eg., buying a new lathe at retail vs a used lathe that's 10x nicer but needs TLC). I know you know the appearance of your projects is directly proportional to the rate at which your channel grows, bc you're a sharp guy. But it makes it confusing when you ignore the finish of your projects given it's impact on growth rates... Anyway, still a fan of your projects, just hoping you'll go the extra mile eventually.

Where can you get a horizontal bandsaw for $100? Your point still stands but I can't find one new for less than $600, and that's the smallest cheapest one I can find. The portable ones are even $450 minimum.

@agentcovert 9 месяцев назад

@@wyattutz each region is different but my point was to pick up a used bandsaw..just an example a new 64.5 inch blade 250lb cast iron metal cutting horizontal bandsaw is $325.USD and used they are $75 -$200 with $100 being very common on different market places..even cheaper a metal chopsaw new is $100 for the abrasive blade type and $250 for metal cutting chopsaw with the carbide type blade..or even better a metal cutting porta bandsaws are $100 new as well..point being there is many choices better then a hacksaw..that's all..

@ED_T 9 месяцев назад

If I would have one point of feedback on the design it would be the following: At 17:39 when you clamp the tool holder in the tool post you can see a gap on the left and right on both sides of the dovetail. The contact surfaces of the dovetail are in the middle of the tool holder. If the two outer flat surfaces of the tool holder would contact the tool post that would spread the bearing surface out and make the connection much more rigid. Looking at commercial tool holders that's the way the high quality ones are manufactured. Either way, I'm very impressed with what you are able to make in your small shop!

@AJBtheSuede 9 месяцев назад

Was about to comment on that too :) Halving the supported width is 4x more deflection per newton of force. And it increases the free lever length of the tool :/ The male dovetail part should only pull the part in, it should never be the main registering surface. Now the entire tool is basically hanging off the narrow part of the dovetail neck, not supported by the available surface on the solid toolpost

@artisanmakes 9 месяцев назад

I didn’t catch that. That should be an easy fix and hopefully net me a bit more rigidity. Cheers guys

@ourtube4266 9 месяцев назад

I just made my first QCTP at work with inspiration from your steel design. It’s 4x4x4 inches and I made the dovetails with wire EDM since I work in die making. It was a big help to see the mechanisms in action before I sat down to draft the model.

@dougberrett8094 8 месяцев назад

In the early 1970’s I learned machining on the job. Tutored by several established machinists. These were the days before ubiquitous NC or CNC, DRO’s, and quick change tool holders. We did use Trav-A-Dials and dial indicators. Every lathe had the 4 tool set up, BUT rather than index at 90° each move, they had indents every 15°. This allowed the same tool to cut a plurality of angles. Think different chamfers here. Now I have two lathes in my garage. They are toys more or less. Both have quick change tool holders. I miss the old set ups. I could rotate the 4 tool holder much faster than changing the so called Quick Change tools. However, one must keep in mind that in a production run, the time to shim was insignificant compared to the one of a kind cuts made in most hobby work. Still, I am tempted to modify the 4 tool holder that came with the smaller lathe.

@wizrom3046 9 месяцев назад

When you tighten it, shouldnt it pull the toolholder flat against the block? It looke to be pulling the toolholder against the dovetail and there is a big airgap between tool holder and block. And, I'm sure you noticed, the moving part of the dovetail is on the wrong side. It should be on the rear and the fixed part of the dovetail closer to the chuck. Anyway, fantastic video and cinematography as always! It's great to see your new lathe getting pimped. 👍🙂

@FWSwart999 9 месяцев назад

If you watched closely, you would have noticed that this is not like the traditional Aloris AXA wedge type tool post/holder. The dovetails are reversed like the Hardinge type. So in this instance the cutting force from the direction of chuck rotation pressing down on the tool in the tool holder will also press the wedge down further tightening the tool holder in the post.

@artisanmakes 9 месяцев назад

I did mull over about which side to put the moving dovetail on. My logic was that the tool experiences a good amount of force pushing it away from the work, so you’d want the face that experiences a chuck of that force to be the fixed dovetail. Cheers

@wizrom3046 9 месяцев назад

@@artisanmakes ... I think of the tool like a long lever, the end of the tool closest to the cut gets the most force so the rigidity needs to be highest at the tool end closest to the cut. But thats just me.

@wizrom3046 9 месяцев назад

@@FWSwart999 .. yeah that is a good point. I think I would still put the non moving edge at the front, and based on your point, the moving dovetail on the rear but inverted.

Turned out really nice, also looks way more solid than the push type holders. One idea tht came to mind while watching: for the holders you could get a big piece of steel and machine a long dovetail along the flat side, then just saw it into pieces. That way the dovetail should be really consistent. Still wondering when you'll cave in to getting a bandsaw :D

@davidbillington9654 9 месяцев назад

Really nice work as usual, I really enjoy watching your videos even though I don't need to make these things. A comment about your radius filing technique though, the way you do it is the obvious one and what I used to use until a lecturer showed me a better way which is counter intuitive to most people but yields better results. If you start the filing with the contact point furthest away from you and as you push the file forward rock the handle downwards so the contact point moves towards you, you should find it results in a better filing action and resulting radius.

@johannriedlberger4390 9 месяцев назад

At 10:20 I see you filing the radius to the wedge. An easy trick is to use the bolt circle of the DRO and plunge with a cutter. Whith a decent number of plunges you need to file only a little bit. Much faster than to use a rotary table and more accurate than just filing.

@user-qo3dc5ww6h 9 месяцев назад

Great video, I admire what you are able to pull off with tools and machines you own. Keep going! Small advice I would give you tho* when reaming.Use a reamer in the collet chuck, because reamers are much tighter tolerances that the runout you get out of the drill chuck. Feel free to measure it with dial comparator, on every single one I measured so far was around 0.05 - 0.1 mm. :D

@jesseservice7828 9 месяцев назад

@MattOGormanSmith 9 месяцев назад

I think the positive dovetail on the toolpost is a better plan for the following reason. When you tighten it, the tool is clamped front and back to the static face of the toolpost. The sliding part of the dovetail is only pulling it tight, with ideally no contact between the "top" of the dovetail and the toolholder. With your design, the toolholder is either clamped only by the face of the dovetail, or you are trying to clamp against the front and back while one of those surfaces (the moving dovetail) is still trying to move under that clamping force. You could put clearance for that in every toolholder so they only contact the solid parts of the toolpost, but you did say you wanted simplified geometry on the toolholders.

@MattOGormanSmith 9 месяцев назад

Or you could take the moving dovetail out and shave a bit off its base so the unmodified toolholders don't clamp against it, as a quick fix

I have a suggestion for your next Shop Upgrade Build Project... Build (or buy) a bandsaw...you really, Really, REALLY should have one... Please get one...watching you hacksaw your parts before cleaning them up on the mill or lathe is painful... 😄😁😆😅😂🤣 After buying or building a bandsaw, may I suggest a Milling Machine Upgrade that should increase the available power at the spindle to take advantage of the increased rigidity... Specifically, machine up a pair of steel gears large enough to span the gap between the motor shaft and spindle shaft converting the Mill from a belt drive to a gear drive and also allowing you to make the motor gear a larger diameter than the spindle gear to allow you to reduce the Frequency you're running the motor at to something closer to what it's designed for while still maintaining the spindle RPM you need for machining...

2 suggestions - 1. remake the wedge to be smaller - that will give thee dovetail a wider more stable footprint while fixing your offset concern 2. integrate tension spring at the bottom of the threaded bar that carries the wedge - that wil ensure any tool vibration will neve shake the tool fully loose

@windrk_6754 9 месяцев назад

Noticed that the dovetail used here is the opposite to a typical Aloris style- especially with the wedge type, I always thought pushing out with the wedge & pulling the 2 ends in against the toolpost gives it a little more stiffness... also, making things interchangeable with something out there lets you take advantage of finding a deal on commercial holders somewhere, since, I find, I could always use just one or two more... But, otherwise, very nicely done - especially the spiral milling!
