One of the most important parts of fixture and tool design is understanding all the tolerances and geometry of the parts you are trying to hold. Hopefully your customer gave you good drawings of the parts. Nice overall concept. 👍
The part does seem to lift even when you hold it down. Perhaps you could reduce the height of the 3D-printed pad so it only touches the bottom? More concern over crushing, maybe, but the part lifting may be a worse choice.
I noticed. I was thinking I could make the plastic bit with a negative slope that would counter act the tendency to lift. I appreciate the observation and possible solution.
@@DudleyToolwright Could also maybe put a thin strip of vulcanized rubber on the face that touches the part just to limit the creep that will happen over time. I also like your idea of putting a flat on that rear pin to prevent any unwanted rotation that could happen with a smaller part as they're locking it into place - although you might have to prevent that pin from rotating also. Love your videos and appreciate you sharing these kinds of jobs.

I agree, but I got no drawings with tolerances. This is a real issue with customers of the laser welding company. They ask, but often do not get.
Nice fixture. We shared this video on our homemade tool forum last week 😎
That was very nice of you, thanks.
I wish we had a McMaster-Carr here in the UK! Great to see your thought process and problem-solving!
That would be a huge win.
Robert - Excellent Fixture - you da man - Jim
Thanks, Jim. It was an experimental approach.
Awesome engineering there. 👍
Thanks, Tom. I love the new metal shade cover you've built. That was a big project, but the results were great.
@@DudleyToolwright Thanks. It kicked my butt, but glad I have it now.
Ditto on the great customer service from McMaster!!!
I am glad that others are having the same experiences as I have.
Nice work.
Very clever idea.
Thanks for sharing. 👍
Thanks for the kind words, I appreciate you watching.
Gday Robert, that’s a brilliant idea and works well, great job mate, cheers
Thanks, Matty. I love new challenges.
I love getting jobs like that,something I've never done before, you learn alot each time, excellent job, great video, keep'um coming..
I agree, it's satisfying when the learning curve is steep.
Hi Robert. Well done, that's a very nice and clever fixture. Good work mate. Regards, Aaron
Thank you for the kind words, Aaron. I appreciate it.
Mc-C has dowel pins with tread holes so you can remove them with a slide hammer puller.
I had forgotten about those. Thanks for the reminder.

12 thousands maybe too little, cause the plastic is gona squish over time, but could print thicker ones.
That is a fear and an excellent observation. As a matter of fact, I printed some slightly thicker press plates before I delivered the tool.

@@DudleyToolwright wont the plastic melt from heat? im not sure how laser welding works. great job on the fixture
