Work Holding Part 3

When it comes to work holding, Festool products are hard to beat. I have the earlier version of the MFT table which is awesome in the shop or as a portable work bench. Using their clamps, I find it very versatile for sanding, routing and other applications. Certainly beats trying to hold with one hand while using a tool with the other. You can even clamp to the side of the table for edge work.

In the bottom two right pictures you see how I use the Festool clamps on a home made straight edge I use for several things. Recently I have been cleaning up the edge on passage doors using a flush trim router bit. Simply mark your line, line up the rail and clamp from the bottom with no clamp on top I n your way! The T-Track is routed into the board. I have several lengths handy since they are I inexpensive and fairly simple to make to make.

I use a T-slot router bit on a router table for this for this. I find it easier to route the middle part first with a 3/8″ straight bit to hog out material. The router table fence can remain in the same position. Sorry about the picture but you should get the idea.

Work Holding Part 2

Last time I promised to show how I use a router for T-bolts, a very important part of my work holding methods. Since there are several different methods, your choice will be determined by both your equipment and your personal preference. I find I don’t do this the same way every time, basically because I live in a perpetual state of confusion. Actually, my methods are usually determined by several factors–like how many am I doing, what size are the pieces, or maybe even which of my tools are free at the moment. Unfortunately, some of my methods are not available to everyone. However, you may find them interesting anyway.

As I prepared for this blog, I discovered the method that most of you can do turned out to be the most logical way to do just a few slots. This method is not restricted to just slots for T-bolts either. I use a lot of slots for my jigs. For this you need a plunge router with an edge guide.

I laid out pencil lines to mark the ends of my slots. Usually the length of the slots are not critical so you can eyeball that as you route. Set the plunge depth to just over the thickness of your material. Be sure to clamp on top of a sacrificial board so you don’t ruin your workbench. For safety and convenience, do not attempt with out clamping. You cannot control the router with one hand. I like to do this in multiple passes. It is safer and does a better job. This is very basic for using a plunge router. Be sure and hold the edge guide firmly against the work piece. I know some of this I information is a bit basic, but I want anyone to be able to do this no matter what there experience level is.

This is what you end up with. This slot is done with a 3/8″ straight router bit. Then I changed to a 1/2″ bit to router the other side for the T-bolt head. Flip the work piece, clamp the piece and with the edge guide in the same position and referenced off the same edge route just deeper than the thickness of the bolt head.

I also use my router table for this application. I use the Woodpecker Sidewinder router lift. Unfortunately it has been discontinued. I choose it because you can raise the bit through the work piece with it in position. JessEm Tools makes a lift you can raise from the side, available from Woodcraft. I am not sure if anyone else does at this point. I used to have to drill a hole at the beginning of the slot and position over the router bit to start the slot.

I placed tape with pencil marks to show the start and stop positions marked on the work piece

With the bit running I can raise it with the side crank through the piece. Be very aware of the bit position and keep your hands away. The feather board helps maintain control as the bit plunges from the bottom. This method is similar to the first in principal. I frequently use a sled for very small pieces which I will cover in a later blog.

I use my Torque Work Center often for this, but since there are so few of these machines in the US, I won’t go into detail for this method. You can see this machine in some of my previous blogs.

And finally, you can just drill a series of overlapping holes with a drill press and clean out with a chisel, rasp, or file. Of course this is my least favorite method for obvious reasons! I did not show this because it seemed like too much work, although I have actually done this in the past.

I hope you find this informative and as always, let me know if you have questions.

I intend on doing a video soon to cover this more in depth if anyone is interested.

 

Work Holding

 

Last time I promised a blog on work holding. This subject has almost become an obsession with me the last few years. I got tired of making do with  c clamps and other ways to clamp something firmly and safely. I grew up in a shop where safety was not always a big priority and as a result saw numerous accidents over the years. Working in production for years influenced my thinking to do things safely, but yet maintain a certain amount of speed. In the next few blogs I would like to share some of what I do to make my life easier while keeping my fingers I intact. There is a reason at 64 years old, I still have all mine!

This time I would like to show the various ways I use toggle clamps. These are readily available from Woodcraft, Rockler and multiple other sources. They come in a variety of styles and sizes, so you can always find one that suits your needs. The first picture shows a coping sled I built for some glass grills for passage doors. It is the same doors I showed in the last blog. Notice the base on the clamp. These, as well as the handle, came from Rockler. Until I discovered these, I typically screwed the clamps to my jig. That is fine for a permanent jig like this one, but for multifunction jigs you end up with a lot of screw holes.2016-09-24-08-25-56

On this jig I have routed a T-slot which allows the clamp to be positioned anywhere by simply loosening the knobs. Because of the style of toggle, this one was raised with a block to allow for the thickness of the work piece. The grills on the last doors I built had some pieces about 1 1/2″ wide and 8″ long with a 5/8″ wide profile on each side. There was no way I am putting my fingers that close to the shaper cutter. The example is not the actual piece. They were much smaller. Now the task becomes a piece of cake!

The cutter is not  for this application.  I just needed to get pictures to show the clamps

Next time I will share some of the other ways I use toggles, and how I route the t-track.

 

Thanks for looking!
