根据各个木友给的意见，为了安全和更紧固，已经将3螺帽改成4螺帽。另外，安全起见，为了防止螺丝在高速运转时飞出来，已经更改为反装螺丝，昨天有木友提到“接触工件的地方改成锥头效果会更好”。所以我将螺帽处全改成锥形，下午使用时效果很明显，工件卡的非常紧，即使电机卡住不转，工件依然没有滑动或变位，安全系数大大提升。（由于是自制卡盘，主要用在DIY小车上，没有那么专业车床那么大的转速和力度，所以请那些用专业车床的朋友不要喷，是否安全已经经过亲自证实。不是谁都会买成品卡盘，实用性是一个原因，价格是另一个原因。可以评论但请不要下什么绝对性的定论，谢谢！）
螺丝倒装以后，在螺丝尾部用角磨机切开一字型，这样可使用一字螺丝刀进行紧固。（由于是单边手工紧固，要想工件转的正，诀窍就是上“卡盘”先别紧固螺丝，然后用 后顶尖 配合固定（同心水平），在旋转调节4颗螺丝的松紧度，然后退出位顶尖，即可正同心，且工件不会偏转！亲测！）
不会磨圆刀。刀头不够锋利，掏的深度还不到位。

Homemade Jumbo JawsFor some time I’ve wanted an easier way of reverse mounting a bowl for finishing the bottom, and have seen several options. Seeing that you can build several of these options, I knew that was the route I would take, as I could not justify spending around 100 bucks for a set of jaws.I’ve considered the Longworth chuck and the donut chuck, but recently I saw some homemade jumbo jaws for a scroll chuck, and thought I could make a set of these for my Talon chuck.The first thing I did was to cut a square of 3/4″ plywood. My two lathes both have a 12″ swing, so I made the square 11″. Since the Talon chuck has about a 1 1/2″ range of travel, I figured this would give me enough travel to accommodate any size bowl up to around 10″ in compression mode, and up to the full 12″ in expansion.Cutting and drilling layout linesI laid out cutting and drilling guide lines, first by drawing from corner to corner, then from side midpoints, and then bisecting the resulting 45 degree angles, resulting in 8 guide lines.

I couldn’t find a compass, so I just marked 5 1/2″ from the center down each line, and connected the dots. Then I cut the square into 4 smaller squares on the tablesaw, and rough-cut the corners on the bandsaw.Cut into quarters and rough roundedNext I laid out the mounting holes using a set of jaws to locate the positioning. I then drilled them on the drill press.I then mounted them on the chuck, and retracted it all the way in. I mounted it on the lathe, and turned the jaws round, and to a diameter that would allow about an inch of travel before hitting the bed. I also turned grooves in the face of the jaws, spaced at 1/2″.I removed the jaws, and then drilled holes along the pin layout lines, spaced at 1/2″.Drilling the last holeHere is a shot of the back of the jaws.

Jaws attached and expandedI made the mounting pins by turning a piece of maple down to 7/8″ and drilled a 1/4″ hole in the center, and parted off 1″ lengths. I used 2″ x 1/4″ carriage bolts, and 7/8″ chair foot bumpers to finish the pins.Mounting PinsThe correct holes to use is determined by expanding the jaws out an inch, and then placing the bowl centered on the jaws. Here I am using a bowl that I originally turned probably 5 or 6 years ago, but never got the base completed. It was green when I turned it, and has warped considerably.

Pins attached to fit bowlThe bowl is then mounted in the chuck. Considerable pressure was applied, and it was held very securely.Bowl mounted in jawsHere it is mounted on the lathe. The tailstock was used for additional security.

Mounted on lathe with bowl attachedI turned most of the bottom before removing the tailstock. I used my homemade carbide tool for most of the bottom.The bottom mostly turnedI finished the rest of the bottom.
