A Bench in the making

First the design stage using 3D tech drawings to highlight the process, It will have a full length leg vice with a self righting mechanism to eliminate the need of a lower pin system to help alignment.

Here are a few shots of how it will eventually look.

I will now add some JPG’s of most of the component parts with sizes and manner of construction methods, these are my own methods but can be adapted for personal use and sizes if needed, there is no hard and fast rule to what height and size these parts can be, in all a pointer of how to do something to get a working bench.

The bench is 500.00mm wide using 100×50mm sections of solid hardwood, in my case beech, held together with biscuits to and bottom along the sides, I will build it in two separate halves before joining the two halves together.
Shown below is the narrower front section at 1.8 meters wide.

Next shot shows the layout of the tail vice, this is made using an extremely strong box jointing method using a 50.00mm framework where the 20.00mm top and bottom plate is either screwed or glued together afterwards

Seen below from the rear side is the layout of the vice, the retaining sliding block and the vice anchor arm to which the screw fastens.
Also seen is the rod housing which has the metal rod that runs along the inside of the vice, this compresses the anchor to the arm and guides the vice as it closes, rod is 12.00mm dia ground/tool steel, retained by external and internal bolts.

Here is the framed section showing the interlocking joints, the top and lower boards complete the structure.

More to follow, vice anchor, screw types etc.

Next showing the vice runner and retaining system along the inside of the vice.

I made my own threaded block but you can use any ready made thread and block or even make a wooden thread also, there are two slipper plate inserted above and below on the vice anchor arm and the square block is also inserted into the anchor by 10.00 mm to prevent it from turning under pressure.

A few sectional shots for reference, end and side rails of the vice box and the retaining block hole, which is 30.00mm deep with a through hole of 10.00mm to the outside edge where the retaining bolt passes and aids lateral adjust after the vice is fitted.

The 20.00mm thick top and bottom boards form the enclosed box section of this vice, which is extremely strong.

All rebates are 15.ppmm deep.

Next is the full length leg vice, I have used and modified a system that has been around for quite a while for the lateral advance of the legs, it goes as follows.

It looks real good, but is it me or is the bench higher at one end? I do think the base looks flimsy for that heavy top. What makes me think that? I have almost exactly that same base on my Swedish bench, although with much wider stretchers (read more stable) oriented like yours, and my bench racked so much that I finally had to attach it to the wall, with a spacer between the wall and the back of the bench to make it stabile enough that I could do hand planing on it. I’m only pointing this out in the hope of saving you some grief, so I hope you don’t take it the wrong way. Good luck with your build!

The version was drawn along the lines of a ready made European bench one of my friends has, which is nice and stable, but it could be altered before I finally take to cutting into any timber, the drawings are in 3D so it might give the impression of not being level on screen.

My friends bench and frame work is joined together by bolts and rounded tenons, and has stood up to a lot of hard work so far, my version will be glued up using through tenons at the ends making it much stronger, the corner where the leg vice is positioned has a 100×100mm post for maximum support and the others could be given the same size if needed.

Solidworks has a stress factoring tech called Cosmos, which has given a 100% stability versus strength analysis vector, which is very reliable and trustworthy technology, but nothing is set in stones as yet.

The cross and side rails are 80×50mm section and slightly thicker than the Sjoberg another friend has.

Only one critique about some benches made from solid top sections as I have witnessed, they tend to move slightly, and why I opted for a laminated top section, using Tite Bond glue for a superior water tight finish.

I will try to make this as cheaply as possible using some recycled timber where I can, a ready made unit is way out of my purse range at over 2G so the saving will be well appreciated in house.

Nearly all of the sections are 50.00mm thick so machining cost will be kept to a minimum.

Thanks for your imput Stefang much welcome.

Looks like a great design, cant wait to see it come together.
