Okay, with most of the headaches behind I figured it was time to dive into the twin screw for the front. This should be easy right. I look at the lumber pile. It is much smaller than a lot of the other jocks here, but it does have a couple of options. I had planned to use poplar, but was thinking it may just be too soft. I had picked up some 3/4in oak at the HD for a project that I haven’t gotten to yet. I figure the oak is a better choice for the vise.
Front chock V1
I second thought this design near as soon as I cut the wood. But I glued it up anyways. A little later natural selection kicked in…
...in the form of low quality wood screw from the borg. Guess it is for the best. I would have wanted to redo the chock sooner or later.
Enter front chock V2
It is just 3 pieces of 3/4in x 8in red oak from Lowe’s. Cost way more than it should have and I had to dig through the whole pile to locate a straight board. I skipped a few steps in haste here, sorry for the poor documentation.
I had located and drilled the screw locations in the mounting block earlier.
I used a forstner bit to transfer these locations to the front chock. I sized the chock to the mounting block and drilled the screw holes in it.
I used the vise screws to clamp the chock and mount together and transfered all of the mounting holes to both parts. Next I drilled pilot holes (a bit size bigger this time around). I also used parafin wax on the screws to aid in thier installment. Between the hole size relief and the wax things went together much easier this time around.
A final test fit.
I am going to have to get some longer bolts to attach the vise mounting block. I have decided not to glue it to the bench, so some big bolts are in order. I may just wait for my giant brad drill bits before drilling, so I can punch through bench top and block in one shot. Accuracy is a bit hard to maintain with these deep bores.
I also took a few minutes to cobb together my temporary vise handles. Nothing pretty. Maybe down the line I can bribe a fellow woodworker to turn me something nicer. For now the 1in oak dowel is capped with some left over closet rod held on with no6 screws. It gets the job done and I don’t worry too much about the kids coloring on them.
I did a quick check to see where I stood with respect to sag.
Doesn’t look too bad. It is less than 1/8in. I had feared it would be more of an issue using these budget screws and loose bore diameters. Time will tell, but for now things are pretty tight.
The vise gives just under 20in of capacity between the screws for dovetail work. I didn’t measure the depth to the screws, but I imagine it is about 5in deep. I get about 6in of clamp at either end. The max open width looks like just over 10in. Anything wider than that I will put on the bench and use dogs to secure. I am excited to get this thing bolted to the bench and see just what it can do. My only disappointment is that the skew is fairly limited. By bolting the chock to the vise screws it has a limit to deflection, probably only 5-10 degrees. If I wanted more I would have to release the 2 screws on the front of each vise. Honestly I don’t see many wedged projects in the near future, so it is not much of a setback.
Stay tuned for completion of the bench.
Time log: Dunno? I have probably dropped 6 hours into messing around on the vise so that puts our total to about 30hr
