I’ve seen (and skim) numerous clamp evaluations over time. Most of them cobble collectively a collection of pseudo-scientific testing parameters and torture checks that appear necessary, however truly do little or no to inform you how the clamps will carry out over the course of years in your store. So after I determined to conduct a evaluate of the Harbor Freight Bremen Parallel Clamps, I knew I needed to method this with a typical sense state of mind. We gained’t be testing the flatness of panels, the squareness of the heads, or the clamping power out there (watch this video to see why – The Fact about Parallel Clamps). As an alternative, we’re going to do one thing extremely ground-breaking: we’re going to make use of the clamps for just a few months. I bought 4 clamps immediately from my native Harbor Freight and used the clamps in quite a few glueups. In between glueups, the clamps had been uncovered to day by day stress by way of mock glueups. One of many clamps was designated because the “abuse clamp” and obtained somewhat extra tough remedy than the opposite three, which included some tough dealing with in addition to repeated dragging of the pinnacle over the serrated bar.
TLDR Conclusion
The video goes into numerous element so you should definitely watch it if you need the total story, however right here’s a fast abstract. Out of the 4 clamps, one failed after just a few months of use as evidenced by fixed slipping underneath strain. After dissecting the clamp, it appeared that the malleable head materials was floor easy, which result in the untimely smoothing of the serrated tooth on the bar. In consequence, the pinnacle may not grip the bar. Oddly sufficient, the clamp that failed was NOT the clamp that obtained the extra abuse. We examined the Lifetime Assure by returning the clamp to our native Harbor Freight and the clamp was exchanged for a brand new one with no questions requested.
General, I used to be pleasantly stunned by the standard and efficiency of the Harbor Freight Bremen Parallel Clamps. Despite the untimely failure I skilled, I believe many woodworkers could be well-served by these clamps particularly given the fee financial savings and the peace of thoughts offered by the lifetime assure. However for those who put numerous hours on these clamps, I believe you’ll be testing that return coverage earlier than later.
