All,

Thank you for the support and great discussion on this topic, sadly after trying for the last three months I can't get the price low enough to be competitive and made in the states without an...

Thanks for the continued discussion!

On the topic of harbor freight clamps, I went out and bought a few for myself and there is no way I would like working with them. I feel like they are going...

Fred,
I have two people who are willing to test out the prototypes and compare them to other clamps. I've done my best to not disclose any details that may give away the design structure of the...

Once again, thank you for all of the solid advice! I cant tell you how much I appreciate it!
At this time I am prototyping a basic bar clamp. There are no extreme difference from the standard style...

Thanks Brian! That is solid advice!

The larger the throat depth the heavier the clamp has to be. It increases the moment against the main beam. For Dubuque they have a very small throat distance for their style of clamp which allows...

I really appreciate all of the responses even if it has became a slight debate about fuel use haha. Through my design process I utilized FEA software to get a baseline of needed sizes/dimensions....

I am about to start making prototypes. I have the prints and models finished but I won't post anything until I have it all lined out and ready for a production run.

It really is a fine line between ergonomics and overkill on the hardware. I think 95% of the battle is simply using quality parts in the first place so you dont need to overkill it to make up for a...

Peter, I agree with your mini rant. As an ME it bugs me as well, I just used it since most people know the term generally refers to a higher grade of aluminum. I will be utilizing 6061-T6511. I...

The Aluminum clamp will be utilizing all Aircraft Grade materials. There wont be any cast aluminum. The idea behind the aluminum series is that it'll be easier to move around and for someone who...

Thank you for the replies, I really appreciate it!
Im looking to have two series, an aluminum series for smaller duty work, and a steel series with a very similar stiffness and load rating to...

Hello,
I have been a long time lurker of this forum but just recently became a member. I am looking into manufacturing bar clamps made completely here in the states. I think we have all had our...
