Machinists....Ever used an inverted Fixture ?? You'll like This One !

In this video I'll demonstrate a technique I call inverted fixturing. It solves a lot of holding problems. Take a Look !!

Machining is 90% trying to figure out how to hold or fixture a part to complete that task. Joe just presented another master class on doing just that. Thanks Joe!

Wow, whoever made those truck sideframes absolutely hit a home run; these are certainly a match for the best (styrene) slide-molding I’ve ever seen, and way better than some of the cast (metal) sideframes I’ve seen in HO scale. 😅 These two-axle trucks (bogies to those in other countries) are typical for EMD railroad locomotives in their “GP” lineup.

Your fixturing skills are amazing! Nobody else teaches how to hold parts like you do.

Never ceases to amaze me with his forethought when thinking of a fixture…😊

Bar none; you have the best channel on YT related to workholding tips/tricks. THANKS!

@Joe Pie The wisdom you shared about work holding is true gold. There are a myriad of challenges gripping such small parts precisely but not distorting precision fit. Thank you.

Great point on the inverted bridge. One point I have seen several times so I will bring it up since you pointed out the "integrity" of the countersinks and the threaded holes. In the aerospace world that was not allowed. The countersink fixes the location of the c'sunk screws. The threaded hole also fixes the location of the threaded screws. There is no "float" to allow for tolerances. It can be made to work but any typical manufacturing tolerances cause trouble because you have four surfaces trying to align the parts. Chances of all four having a perfect fit (zero tolerance) are slim to none.

taking time to hold things firmly so broken tools or entire setups from the floor is the best time ever spent on a job. You continually show us the value of doing that. Who knows, perhqps one day the holders will be used again giving them real value in time saved. Have a beauty weelend Joe.

Be glad its O Guage instead of HO or N 😁. I used to have C/Sinks and C/Bores for small screws that had pilot diameters on them. Two flute. Worked great for small screws

[MyLilMule]

As usual, wha a great tip! As a hobbyist, I rely on professionals like you to learn from. Thank you, Joe!

[johnjohn-edqt]

Your videos are a nice addition to Colvin and Haas in how to fixture

[HenryArndt-hhfx]

Thank you for solving a problem we encounter from time to time.

Good fixture, Joe.We badly need some leadding.Thank you.God bless us all.

[ramonching]

Thank you. I was trying to find a solution to this similar problem. Thought of you. 😁😁😁

Machining parts is like Painting Houses or anything else, you spend 90% of your time figuring out and doing Prep/Fixture work to make the other 10% Machining go smoothly. Neat fixture Joe, I'll have toss this one into my bag of tricks! 👍👍

[jaybee]

Beautifully done. Thanks for posting this, Joe.

Got my fixturing fix fixed. Keep up the good work

[KevinLeyerle]

Looks great Joe! Seeing your method of doing this type of work is extremely interesting. Really looking forward to putting these in service on my layout.

[skwerlz]

Nice! My gut reaction was a couple of soft plastic fixtures but this is far more elegant.

[Dagonius.]

Brilliant Fixture Joe!
Turning a difficult part into an easy part!
