Novice Machinist 4 - Two Vises

So here are a couple of more advanced projects for the novice machinist. The first, a model makers vise, is very handy for doing small work on the workbench. It is all made from cold finished steel (crs).

The second vise is a nice woodworking vice. If you have been looking for a nice aluminum casting project, this might be it. Many years ago when I built my first melting furnace, a drill press vise was one of the first projects I did. This plan is a little more advanced but I would not consider it difficult. The patterns are relatively straight foreword, note the draft lines in the drawing. Draft is generous in the deep section to ease pattern withdrawal from the mold, without damage.

Both of these plans will produce very useful shop accessories that are becoming quite expensive in the retail market, and you will have the satisfaction of having made them yourself.

An Indicator, A Vise And A few Quickies

So back to the metalworking shop here is a plan for a nice clamp-on model maker's vise, a cleaned up and clearer scan of a test indicator for the lathe and around the shop. There is another method for cutting keyways in the lathe and a quick little jig for drilling round work.

Keyways are a characteristic common to most shaft, motor, and pulley assemblies in shop built machines of wood or metal construction. Just set screws can come loose and score shafts, keyways and set screws are a better way to go. Above is another idea for cutting keyways in the lathe. If you have a compound slide or have built one from the couple of plans I have posted, you can cut keyways using the above idea in the wood lathe as well. Don't try to hog it off in one pass, feed slowly taking a number of passes to reach the depth required.

If you use this method use a high power low speed drill, like the one below. I purchased this one shortly after "Mastercraft" came out with it. I liked it so much I bought a second one. Lots of power, it draws 7 amps, and the reversible variable speed runs 0-650 rpm. I work them as hard as my Makitas and so far they are holding up well.

Machine Vises

Well looks like this long winter has thrown off even the bears. Timmins is already having a bear problem. Easier to climb into a dumpster than dig through 3 ft. of snow, ha ha.

I found a nice plan for a welded steel vise, so I thought I'd do a write up on vises. Machine bench vises are often subjected to heavy, rough work. I have found over the years that they are not always made the same and going with the cheaper imports often turns into a lost dollar. A statement like that needs some qualification so here goes.

When it comes to imports quality seems to have taken a hit since China became the dominant player. I have two imports that I purchased back in the early 80's. I have them mounted on mobile 3 legged stands and they have been subjected to huge amounts of abuse, rough handling and over tightening. Never a complaint, they are like the day I bought them. Back then the imports were coming mainly from Taiwan.

Since then my shop space has increased and so has the need for more vises. I have 6 vises mounted around the different shops on benches, (yes I know, overkill ha ha). Importers will go with the cheapest suppliers so when China dominated the market, thats where they came from. Unfortunately they do not hold up to my 2 old imports. Over the years I have destroyed three, a 3", a 4" and the latest a 5", a couple of years ago. Here's whats left of it. The rest got melted, back when I tested my furnace. I now have more small bench anvils than I will ever need, lol. As you can tell from the dimples, the iron is too soft, (Poor metallurgical control??).

If money is no problem, heres one that is industrial quality all the way. Wilton makes a full variety of sizes and types, you couldn't break one of these if you wanted to.

So I am to poor to dish out the kind of money Wilton wants, and I would prefer to avoid the imports, so whats the alternative? Weld your own. I have seen many pictures of guys welding their own over the years and some of them are truly outstanding.

Going through my files I found a plan for a welded vise that looks solid, without complication and made from easily obtained materials. In my case, it wouldn't cost a penny, I have everything required. You can easily size it to suit your needs. Here's the plans.
