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.

Novice Machinist 3 - More Small Tools

So here are 5 more small tool plans from "Metal Projects Book 3". These projects are excellent, useful, projects for the beginning hobby machinist. If you own one of the inexpensive import lathes and/or mills, or even better have built your own, these will get you started with set-ups and procedures. Materials are mostly crs (cfs), tool steel, and aluminum, materials that are easy to source and work with.

"Cutting Tools For Metal Machining"

Here is a book that will prove very useful for hobby machinists. No matter what sort of machines you have, none of them can perform up to the standards they were designed for, without proper tooling, properly ground.

"Cutting Tools For Metal Machining" was authored by Max Kurrein and F. C. Lea in 1940 and published by Charles Griffin and Company.

I did not clean up the djvu file, but the file is a reasonable scan with pages complete and reasonably well centered.

Novice Machinist 2 - Small Tools

As mentioned in the Novice Machinist 1 post I have a few books of projects for the student machinist. These are full of small tool and accessory projects that are both, instructive learning exercises for the novice machinist, and useful tooling for the hobby shop. Degree of difficulty ranges from simple to advanced, with the majority of projects falling between. Look for other posts from these books titled as "Novice Machinist ...".

These projects were designed for the student machinist. I can't stress enough the need to exercise safety practices in the shop. The lock on your shop door should not let you in, until you put your safety glasses on, no exceptions, and I know your tempted, I am, but never clear swarf with your fingers while a machine is running, if you enjoy having fingers.

The first book is titled "Metal Projects Book 3" by John R. Walker and published by Goodheart-Willcox in 1977. There are 3 or 4 good posts here. I will start today with 4 small tools that will find use around the shop. The accuracy of a tool like the adjustable square will be the biggest challenge, in this little collection.

These drawings are sized to be comfortable to work with. To save, first expand to maximum size (may require two clicks depending on your tech.) and then click "save as".

So we got nailed with 15-20 cm. yesterday and over night. Those snow banks are starting to get deep already and we just started into December. As one CBC comedian said "Damn it Winter slow down, at this rate you won't have any snow left for March." LOL. In my case thats probably April, those Torontonians are spoiled. LOL.

Novice Machinist 1 - Machine Stops

So here are plans for 3 machine stops for the novice machinist. These come in handy around the workshop no matter what material you work with, for producing repeat cuts and finishing to a positive stop. I have at least three books full of small novice projects like this, I'll post more in the future.

I found this plan on the web back in 2006, so the source escapes me now. G.W. Farquhar did the fine drawings.

Pipe Carrier And Static Balancer

The first project plan here is also from "Arc Welding Projects" Volume III. This one is a pipe carrier, but not just a pipe carrier. This is another one I will be looking to build in the new year. I will be widening out the distance between the wheels. Why? Making it wider will allow me to use it for pulling heavy logs out of the woods, as well as moving pipe and steel sections out of storage, to the workshop area.

I have seen more complicated ones that couldn't do what this one will do.

The second project is a 1 page plan for a nice static balancer. My apologies I can't remember where I got it from, I found it printed off in one of my project binders. The plan is sized for balancing dirt bike wheels, so it may have come from one of the many motorcycle sites out there. It is sized for bike wheels, but of course you can balance anything that will fit inside the frame.

The plan is only one page but it is very complete, with full instructions. Dave Gingery built a smaller one in one of the Workshop Series books, but this is nicer and probably easier.

12-Ton Shop Press

Here is a nice clean 12-Ton Shop Press welding plan, from The James F. Lincoln Welding Foundation's "Arc Welding Projects" Volume III.

I currently have a smaller bench mounted 10 ton shop press. It is handy for smaller work and gets used often for bending, straightening, and pressing jobs. I have had occasions when a larger press would have come in handy. The plan has always been to build a larger 20 ton floor mounted press. To that end I acquired two 20 ton jacks, long time ago when the price was right. One for the press, and a second one for back-up.

Now that the steel I need is sitting in storage, I am looking at building the 20 toner in the coming year. The plan will be very close to the 12 ton plan below. I like this plan, it is overbuilt for 12 tons and I will beef it up again, for the 20 toner.

If your interested, there is nice complete step-by-step build instructions here, for building this tough looking little guy.

How To Make A Metal-Bending Machine # 10

So from Intermediate Technology Publications comes another of their Workshop Equipment titles. This one "How To Make A Metal-Bending Machine # 10" is the last of the paper copies I have. Like the other two, it cleaned up nice and is complete.

The first half of the manual shows you how to build the bender. The second half of the manual shows you how to build a steel wheel for a agricultural cart. Now your probably thinking "What is wrong with this "Bozo"? What am I going to do with an ox cart?" ha, ha, lol .

But of course you can bend up countless other shapes, for many different projects, with this bender.

A Forged Bear For My Future Gates

So when I first built this place I installed a couple of wood gates at the entrance, hung on two 8' X 8" drill pipes sunk into and filled with concrete. They served there purpose of keeping scroungers off the build site, while I was still living off site. Shortly after I moved in I left them unlocked one day, a strong wind blew up and pulled them off their hinges. Rather than reinstall them I brought them up to the house and installed them as a wind break and snow fence alongside the turn around area.

So as you can see in the picture above the posts are still there, waiting for a new set of gates. The plan is two bend up two large, shaped frames to which will be attached verticals every 6 or 8". Adornment will be in the form of forged wildlife shapes common to this area, attached to the verticals and peaking around corners. A nice idea but I am not getting any younger.

So below is a nice step-by-step plan for forging up a bears head, perfect for my gate idea, I have a number of other plans for forging other animal shapes. Mark Aspery is the author, a blacksmithing instructor, he forged this bear head while attending an instruction class at a school in North Carolina.

An Easy Guillotine Tool

Guillotine tools are very useful helpers for the smith who works alone. A good one will cut your time in shaping and cut-off operations depending on your selection of dies. Dies are easy to make, so it's a simple matter to have a good selection on hand to suit the type of work you are doing.

I have seen many ideas for making guillotines around the web over the years, some are more complicated to make than others. Many have probably seen the one I am posting today before, it has made it's rounds on the web. It is one of the easiest I have seen to build, a few workshop scraps and some welding is all you need. A small price for the huge help this tool can be.

The plan was originally published in ABANA's "Hammer's Blow" newsletter. I got this copy from the "Saltfork Craftsman" newsletter of August 2005.

Atmospheric Forge & Heat Treat Oven

So I spent yesterday morning running errands and settling in for winter. I was almost home when the blizzard started, It blew hard all night and is supposed to continue all day today. Nothing else to do but cook up some tasty treats (winter's coming on, like the bears, a little insulation will help, lol) , fire up the wood stove, and settle in in front of the computer, for the week end. Life is good ha, ha.

Near the top of my build list is a forge, soon I hope. I have lots of plans for forges, and some ideas of my own. One plan that I have always found attractive was published by David J. Gingery Publishing back in the 90's. It was built and the manual written up by William T. Goodman and Robert W. Holmee. It has a very nice appearance but I would make some changes to the shape and refractory of the firing chamber. The refractory in the plan is a little thin in my opinion and there are more efficient materials that can be used today.

It took me a while to find this book, I think I eventually found it on a torrent site. The scan is not great (I cleaned up the two pages below), but it is complete. So if you would like a proven plan for a nice and very convenient forge or just want some good ideas for building one, this should do it.
