They're....ok after a lot of modifications
Like a lot of other recent reviews, I had massive issues getting them to hold. After spending a lot of time with some files they are kindof ok. Mine had some really terrible mold lines on the front and back that I filed down to get them back to somewhat round. I also used a triangular file to rough up the front and back faces (the faces that touch the holes) and they now grab a little bit. Not well, and not always the first time, but I can get them to grab finally. I've also found they grab a little better if you whack them at about a 45 degree angle on the bent portion of the neck instead of straight down. I certainly wouldn't recommend them, but I at least got mine to somewhat function if anyone else is in the same boat.
Does not hold
Bought these for my bench top. Recieved, followed directions to drill holes, and they will not hold!!! Highly dissatisfied with this purchase considering i spent 2 months building my bench only to drill worthless holes in it!! Not happy at all.
Not for 4" Thick Benches
1 star for me but might work well for others. Two issues with these holdfast. First, for me, is they do not hold in 3/4" holes in 4" benches. I finally tried them on 3/4" holes in my bench legs that are about 3.24" thick. They worked but not great. The problem appeared to be the finish on these holdfasts. I sanded and scuffed them up and now they work great in bench legs only.
Holdfast v. Sjoberg clamp
The large holdfast has worked well on the Sjogberg tables which have 1" diameter holes, but I needed to cut off a portion of the long support to get it to fit. The Sjoberg clamp works better but not as quickly.
Speeds things up!
Received one for Christmas. Drilled 3/4" inch holes in 1 1/2" tabletop and the holdfast works great! Bought one more afterwards. I wanted them for carving, and chiseling operations but I used them on a board glue up and they worked so well I will probably buy one or two more.
Too smal for 3/4" dog holes
Bought in store Jan 2019 and had to return them. Two different brands of 3/4 bench dogs fit a bit too snug, but these were really loose. If I whacked them hard enough to hold anything down, it would bang up the dog hole opening and even then they would slip with a little bit of movement. Measured with calipers they were just shy of .7" Bench is pine, 2 1/2" thick. Holes cut with carbide forstner bit.
So far so good
I've been using these for a few months now, and they have been working well. I lined the pads with cork to prevent marking the workpiece, and also to give it a little more grip. My only complaint with these is that they are fairly stiff, so every so often it takes an extra whack to get them to hold completely. Overall, I'm pleased with them in my 2" thick benchtop. Some other reviews have mentioned using an 11/16 hole instead of 3/4. I don't know if the design has changed (some of those reviews were from 3 or 4 years ago), but mine would not fit in a 11/16 hole. I drilled both sizes in a scrap piece, and the 3/4 inch hole worked for me.
I use this product to hold down boards as I chops mortises or remove the waste from the pins and tails when making dovetails. Anything that needs to be clamped to the bench top can be done easily with this tool. All you need is a 3/4 inch hole and a mallet. Just give it a real good whack and you are set. To remove just smack the back of it with your hand. I did add some leather pads because the foot was leaving marks on the wood.
It's not what I expected!
The catalog description says to use a 3/4 in. hole; now I see that 11/16 (or something smaller) is the recommended size. Too late. Also, the holdfast is a painted casting, not forged, and very rigid--a combination that produces no grip. From Woodcraft, I would have expected consistent instructions and a product that would work 'out of the box.'
So easy to use and so effective!
This holdfast is great to secure pieces especially closer to the center of the bench. It is quicker and easier than using clamps at the edge of the bench. Perfect for holding flat pieces down for edge treatment or boards for end treatment. If you have to move the piece often, this holdfast is easier to ise than the bench vise because you don't have to deal with moving bench dogs. One cation though! The item description says 5/8 inch shank. This is NOT accurate. The shank is 11/16 inch. And as someone else pointed out fits in and works great in an 11/16 hole. I have 5/8 dog holes on my bench and thought that this would fit in those. It does not. I had to drill strategically located 11/16 holes for this. While I can or use it in the dog holes, I still find it very effective and easy to use.
test it on a scrap first
This dog works great in a 11/16 hole. the instructions say to use 3/4. I wish I had tested it before I drilled those 3/4 holes in my bench top.
What can be said about a holdfast!
I use the holdfast to hold parts fast to the work bench. It is fast to clamp a part and equally as fast to unclamp.
It's what you want from a holdfast
These are simple and shouldn't be scrutinized too much. It's simple and does what you want it to. The only downside is that TAIWAN is stamped in the neck, oh well, better than CHINA and not as good as USA. nice and heavy/sturdy. Enjoy.
Holdfast works as hard as I do
acquired an Oak woodworker's bench with 3/4" bench holes. bought the bench dogs and the holdfasts to help set up and work on porjects. Both work better than I could have imagined and they will be in use until I quit doing the work.
Unpack, Drill 3/4'" holes and put to use. Wish I had done this a long time ago!
Works great on a 2" thick top
This holdfast is simple and quick. To improve its performance, glue a piece of leather to the clamp pad so it doesn't mar your workpiece. If it slips, roughen the shaft with 60grit sandpaper. It needs friction to work, so if it slips it is an indication it is too smooth.
I'm probably doing it wrong
I most likely drilled too big of a dog hole (3/4"), but it's a great benchdog, especially used on the side of the bench - plus it looks oldschool cool. I'm not recommending it because I haven't got it to work - I'll probably get a Veritas stay and just have the holdfast as a benchdog.
