Eccentric clamp alternatives?
Hi there, just wondering if the Felder eccentric clamp is worth it? No Felder shop in Australia, so we pay a premium with delivery to Australia. Can anyone help me with the T nut dims thread size? Is it M20 right into the tnut or am I missing something.? What's a great aluturnative? Is there planes for a retro fit,?
Thanks Chris. |
开云体育Chris, I have a brand new one if your interested in it. ?It came with my saw, but never used it. Thx, Wade On Dec 27, 2023, at 2:30 AM, Chris <Hope752@...> wrote:

guys- Chris is in Australia. ?I don’t know if you have ever done international shipping, but it is EXPENSIVE!! ? The Felder eccentric clamp is seriously heavy and big. ?It’s likely going to cost you another $250 USD just to ship it uninsured to AUS! ? Likely not worth it, unless he really wants this clamp, lol.
Chris - those of us who have not gotten Mac’s air clamps will generally use the following combination for Felder sliding table slots (with Australia seller links): The Kreg bench clamp works great and is fast and easy. ? Just keep in mind that the Kreg clamp tends to pull the material back just a big when clamping down (like about 1mm). ? The 6” Kreg clamp will actually reach over the Felder crosscut fence, so you should clamp down that forward clamp first. ?It will pull the material against the fence. ?Then you can clamp down the rear clamp. ? Or make sure you hold down the material while clamping and you should be fine. The Felder clamp, on the other hand, will tend to push the material forward when clamping, so it works great as a rear clamp, but not so much as a forward clamp (reaching over the crosscut fence). -Aaron |
I’m not really a fan. I used mine a lot when I first got it. To the point that it stripped out the holes from repeated use and I had to re-tap to use beefier bolts. I’ve switched to using a modified Kreg clamp behind the fence and a modified quick action track saw clamp on my side that I snug up against the work. By modified, lol, I mean I welded on a couple washers that fit exactly in the slots of my slider. I’ve been happier with this setup than with the Felder clamp.?

开云体育I ship stuff to Australia often, $250 is not going to happen. I send a parallel fence, 11 pounds, 9x9x36 box, insured for $1300 and it’s less than $200 last time I did it. I just went to the USPS website and calculated cost, a 15lb box, 12x12x12 is $182.90. It’s based mostly on weight, so depends on what those things weigh.Brian Lamb blamb11@... www.lambtoolworks.com

开云体育My experience echoes that of Aaron. The eccentric clamp is heavy and awkward. There is a learning curve for achieving just the right depth setting, and it moves the workpiece forward. Perhaps there are situations that require the extra strength of the eccentric clamp, but for the work I do with 3/4 inch sheet goods and up to 8/4 hardwood, the Kreg type clamp is adequate and more convenient.Steve

开云体育I had eccentric clamp on FD250. The part I disliked most was that, when unlocking, if the handle got away, it would travel all the way and eventually stop after hitting the material. Not sure if this happened because my clamp was old. If it happens on a new clamp, it is a shame because it dented soft woods like cypress and cedar.Someone on FOG gave me the idea to flip the puck in the clamp. This swapped the clamping and unclamping motions - clamping with handle moving towards material and unclamping with handle moving towards the horizontal bar. This solved my problem.

开云体育FYI I ?would never use usps international as the last time. They stole 700.00 from me .?They insured my package and charged for it then customs refused the package in Chicago saying ?I couldn’t insure it for that amount!!!!!!! Trying to collect from United States Postal Service priority they said go to United States Postal Service to collect United States. Postal Service said. They do not support anything shipped with United States postal online shipping.? I took it to postal court and quess what ,, lost. .? So I than put a claim against visa debit and after 3 months WON .? They could fight the__________! I only use DHL for international. UPS is stellar in what they do . Anything over a grand gets white glove treatment. fed x never does what they say there going to do .

I’m not a big fan of that Felder clamp either. It’s too big too heavy bulky and difficult to adjust. I used to have a Mini Max, and theirs was just right. I’m going to find a different one to use. Actually thinking of hijacking a Mini Max clamp and finding a machinist to mill and drill a bar for me. Anyone already done this?

What I'm really interested is the tnut and top oversized washer dimensions if any one has them. Does the tnut have an M20 thread and the top washer just a pass through? Or is the tnut and washer connected regardless of the M20 post? Any pictures would be appreciated. I can design my own clamp system. I should know that I haven't received my kf700 yet so can't measure the slider slot etc.
Thanks, Chris. |
Chris, ? The dimensions are not super critical. ? You want the T-nuts to slide easily in the slot. ? If you are making them, check the fit along the entire length of slider as some of us have found that the extruded slot is not completely uniform and you may have a tight spot. ? Make several nuts and insert them on both sides of your normal fence set up so there is always one where you need it. ? Make the large washer at least as big as the Felder one so you don't distort your table. ?Add a soft face to the underside.
Below is one of my Kreg clamp t-nuts. ? I did not come up with this idea but it is brilliant as these clamps are much easier and quicker to use. ? You just drop them in the keyhole slot and slide them over. ? These do need to be pre-adjusted for height as you don't screw them in (which is why they are so convenient). ? A couple of set screws allow you to adjust the nut for a nice sliding fit in the slot and match the top surface height for all of your t-nuts. ? This allows the cap screw head be set once at just the right length to engage any of the t-nuts without any further adjustment (some thread locking compound is helpful here). ?? There's an ever easier option if you happen to have Festool clamps and lack machining access. ? ?A simple piece of off-the-shelf T track can be put upside down in the slider slot and and used with the Festool track clamps. ?The fit is a little sloppy but this is a 5 minute project if you have the parts handy.? |
A few months ago I purchased a Compass AH-3 from Harvey $220 and it works great. I will not used the eccentric cam clamp again.?

Chris, I purchased one from Just Tools (in Perth), but they have closed down in Oz. I searched on the Web and noted these ones on Ali Express.

Hi Bill, The T-slot version (AH-3T) fits my SCM slider with no modifications.?
