Twin screw vise #7: Getting it working

12-10-2017 07:37 PM by Dave Polaschek | 6 comments »

I’m a little light on pictures in this post, as I got excited that I was almost done, and didn’t want to stop to take pictures as I went. Sorry in advance for that. When I left off in the previous post, the dowels that will hold long pieces off the vise screws were binding and wouldn’t allow the jaws to close. So my first order of business was to open up the holes in the front chop a little with a tapered reamer. I did that slowly, sneaking up on the fit, repeatedl...

Twin screw vise #6: Both jaws on

12-09-2017 08:14 PM by Dave Polaschek | 4 comments »

Since last time, I finished drilling the 3/8” holes to mount the rear vise jaw to the bench. I bolted the jaw on, then put in the vise hardware with the front jaw to make sure everything lined up. The one departure from plan is that the 5” bolts supplied with the vise were long enough that I needed a little more wood behind the bench apron to hold the nuts. They’re designed to live inside the bench top, and I had initially planned to put a 2×4 behind the apron to...

Twin screw vise #5: Boring the holes

12-06-2017 05:56 PM by Dave Polaschek | 9 comments »

In the previous post, I left off just before drilling the two main holes for the vise screws. Yesterday I did those. Based on feedback from some fellow Lumberjocks, I used my expanding spade bit to start the holes, as it has a nice sharp spur and produces a clean edge. Then I used the old T-handle auger bit I bought off eBay and cleaned up, which has no spurs (it’s designed for drilling holes for timber-framing, so I suspect a slightly ragged hole wasn’t a worry). I built a jig...

Twin screw vise #4: Everything but the holes

12-04-2017 06:08 PM by Dave Polaschek | 15 comments »

I’ve been working on getting everything prepped for installing my vise, and I think I’m running out of things to do. Looks like I might have to drill the holes for it this afternoon if my back behaves. I’ve removed the planing stop from my bench. It was going to be in the way of the vise. I also filled the holes where it had been with walnut dowels and planed them smooth. I’ll reinstall it once the vise is in and I figure out where it needs to be. I’ve ...

Twin screw vise #2: Rear chop and thinking

11-25-2017 04:02 PM by Dave Polaschek | 13 comments »

Having the front chop done-ish, it was time to move onto the rear chop. It was less tapered than the front one, so just a few swipes of the plane took off the 3/32” or so that was needed to get it square along the long sides. But the ends were more angled, and since I wasn’t rounding them off like I’d done with the front chop, I wanted to get them nice and square, so out comes the shooting board. Once everything was square all around, I used a spokeshave to bre...

Twin screw vise #1: The front chop

11-23-2017 05:20 PM by Dave Polaschek | 9 comments »

This winter I want to start cutting dovetails, doing a dovetail a day for a month to build my skills. In preparation for that, I’m adding a twin-screw vise to my bench, using the Veritas mechanism. I’m planning to make the jaws three feet wide, with a full 24 inches (minus a little) between the screws, so I can also use this vise to hold wood I’m resawing with my frame saw. Since the front chop is going to be the most visible bit (even though a lot of it will be covered b...

Work Bench Constuction Journal #1: My Dream Workbench - A Journal of Progress

01-24-2012 10:41 PM by Ron Ramsey | 21 comments »

I have finally gotten around to making a real workbench for my new, and smaller, shop (see my previous entry). I am in the planning phase right now. I’ve been pouring over plans, books, philosophy of workbench design. I guess it’s safe to say I may be over thinking this. But the design is half the fun. So, I’ve put together a journal that you can download and look at. It has pictures and explanations of some of the design considerations I’m mulling over. I am ...

Workbench #7: Twin Screw vise is DONE

08-03-2009 07:52 AM by Rob Drown | 4 comments »

I finally shimmed the brackets on the correct side and added matching shims on the opposite side of the front vice bearing and vola. turns smooth as butter. The front vice jaw is planed and sanded and has bench dog holes drilled in it. The TSV is Done. All it needs is a coat of oil, boiled linsead oil.and it is DONE> You can see the bench dog holes drilled in the apron, it is ready to be glued on to the bench. Then it is time to move the top off the legs, fix the wedged tenons, fli...

Workbench #6: Twin Screw is almost finished

08-01-2009 03:57 AM by Rob Drown | 4 comments »

The front face is mounted. I need to attach the chain cover, then disassemble everything, drill dog holes, finish plane the jaws then apply the oil finish. The tolerance on the holes was much larger than I thought. I put way to much effort into straightening the holes. There are 3/8ths pins that keep what ever you clamp from resting on the screws. The instructions indicate that you are to drill holes for these pins on the inside face of the rear jaw tangent to the screw hole. The sc...

Workbench #4: Base is almost finished. Top is on the base, upside down. Time to build the twin screw vise

07-23-2009 05:51 AM by Rob Drown | 5 comments »

It has been a while since I posted stuff, so first I’ll catch up. I finished the mortises and tenons and assembled the legs and stretchers. The legs are very square and stable but the mortises are not as tight as I would like. They are going to take some fixing. I have put the top on the frame up side down so that I could attach the vices easier. I built a large standard single screw vice and mounted it as the end vise. It didn’t come with instructions, so I must have taken t...
