Thinking I was going to be moving most of the bottom group of lumber in the wood storage pile to get to the wood for the vise chop. I had MsBubba standing by with gloves on her hands to help find the best board for the chop and maybe save my back and a trip to the E.R. After moving the scrap barrels out of the way what do I find but the perfect 8/4 hunk of Beech on top of the lumber. All I had to do was bend over and pick it up. As I have often said...."It is better to be lucky than good".
Here is the vise chop board in place:
Because the Fujiflim X-Pro1 battery is dead and the charger is in the Motorhome (still in the shop waiting for a part) the photos are coming from my iPhone. Making them look right in Photoshop is more work than I want to do. Sorry. Also the dog holes really are vertical in spite of their looking like they are drilled at 45 degrees in the photo. Anyway here is the bench top with the installed planing stop and a row of dog holes.
Looks like the bench may be finished in time for the Oregon trip.

How is the holdfast holding when skewed laterally?
ReplyDeleteHoldfat holes don't need to be perfectly perpendicular to the top anyway.
It seems the best angle of the holdfast stem with the hole axis is about 7°.

In my view, it works like a pipe clamp, the top acting as the lamellae of the clamp.

Sylvain,
ReplyDeleteWith the slab being 50mm the holdfast work in any direction. In my experience if you get too much under or over 50mm holdfast can become cranky. On my French/English bench with a 100mm slab I've had to counter sink several of the dog holes from the bottom to help the holding of the holdfasts. I'm not sure of the geometry of "why" but that is what experience has showed me.
Thanks for the link, just back from reading it. I had not seen it before but it confirms what I've experienced with using holdfasts. BTW, I have a few Veritas screw holdfasts that work very well but because they are slower to use their use is restricted to long term holding such as holding the Moxon vise to the bench and holding things where it is important that the piece does not move during the securing.
