Dust collector for angle grinder

Whenever we cut dry walls inside the house, everything is covered with fine dust no matter how much effort we put into covering the furniture.

The attachment shown here is an easy way to solve the mess and avoid the dust. It collects all the dust generated when cutting stone and dry walls. Of course, one can buy such upgrades but I had nowhere to buy it during the weekend so I built my own.

Made from 2 mm sheet metal and mounted to the grinder using modified blade guard.

Tablesaw Fence Jig

Even thou I have not used it much I believe this easy to make jig has potential for cutting obvious tenons but also for more complicated cuts such as compound angels and other difficult to handle cuts.

The initial built was made in order to create shelves, for a bookshelf, which multiple angles creates a unique bottom flowing from full thickness in the back to blade like front. This worked well and the cuts came out as planned but I never built that shelf or used the jig again.

Nevertheless here it is, with sample of compound cuts and hopes to make it more useful.

Bosch table saw riving knife

This post is relevant to owners of older models Bosch table saw (4100 and GTS 10) who may be interested in using a cross cut sled without removing the riving knife. Well, once you removed the guard you removed the riving knife as well and therefore the only work around is to create an alternative, a metal stand alone riving knife.

 

As you can see in the pics below, this is a simple metal plate cut to shape which you can copy from the existing riving knife. There are no critical measurements here except for the part held within the saw and the thickness of the plate which should be kept at blade width or thinner.

Workbench wheels lift mechanism, failed

Everyone knows the wheels lift mechanism you install under the workbench to lift it off the ground and on the wheels, the one that is shown below.

Installed several years ago, it worked very well and served me by making it really easy to move the workbench around the shop and keep it in place without moving when needed. Apparently I needed it to move more than stay at position and only now I discovered that keeping it on the wheels most of the time caused the wheels plate to bow. It is made of hard Ipe and I expected it to hold forever, but it didn’t.

In the pics below you can see the deformed board.

Backlash probe for Mach 3

As a result of struggling with backlash issues much longer than needed I built this probe and wrote a small VB procedure to help read backlash values within seconds. The probe is similar to edge finder which rises a bit on the parallel interface when grounded. The electrical connection is made between the probe and the spindle using two alligators and required an isolated base which is made of clear Polycarbonate. At the base are two rare earth magnets which holds the probe on the milling vise or alternatively between its jaws. The audio jack plugs into a connections box which leads it to the controller.

The script is self-explanatory, just notice the settings under “User Inputs” and make sure to select the correct values:

Resolution – If you need an immediate low-res (i.e. non-accurate) backlash reading you can run at 10 or 100 and the feed rate will be set respectively (the resolution will be low but the speed will be high). For final reading always use 1000.

Active Axis – Simply set to X, Y or Z and place the spindle (or tool or whatever is attached to the spindle) between probe’s brackets, somewhere in the middle, and in a way that will allow the brackets to touch the spindle when the axis moves in both directions.

Two Sides – This is useful for Z but can be used on any axis. When measuring backlash I always read it in two directions and set the average result as backlash compensation. With X and Y there should be no problem, but when doing Z, how do you set a tool to touch the two brackets of the probe? You can use any tool such as fly cutter, a bit with extended tip or a hex wrench attached to a drill chuck. Otherwise, you can set this parameter to False and the script will run the axis in one direction, which is going down to the table.

Number of loops – For some reason I initially wrote the script with an option to run multiple cycles and display the average reading but I never used it and always run once. It is there in case you find it useful.

The code can be found here, open the VB editor and paste it there. Always remember to “SAVE AS” or else Mach 3 might use a previously stored file name and overwrite existing file you may need.

Tryally’s Slim Vise

Update (03/2015):

Luiz send me an update on his Slim Vice and I am happy to share it with you.

You are welcome to download updated photos and instructions here and my original SketchUp plans in the link below.

Original (03/2011):

I guess every Sherline owner knows Luiz Ally (Tryally) and his videos on YouTube including the one about his slim vise which looks like an excellent solution for holding small and thin objects.

If you are interested in building such vise you may find the attached file useful.

it’s a SketchUp model I’ve designed with minor modifications from the original, what I was able to see on the video. I have not built it yet and not sure if I will go for the exact solution or to something similar based on a tool plate, we’ll see.

So for now you are welcome to download the file and feedback if you have any comments, and I repeat, I have not built it yet so  it may contain errors.

Design credits to Luiz of course.

Nati’s metal and glass service table

Nati is a very close friend who lives nearby and so most of our meetings are held at my workshop and finally something came out of it. This service table is made of 10 x 10 mm metal bars welded together using my Miller Passport MIG welder.

Part of the process was to flatten the bars which are made with a roundover we didn’t like so we built a jig to hold an angle grinder under a table we then used to feed the bars over the grinder.

The initial thought was to cover the table with clear varnish but then we decided to paint it red against the off white painted glass.

Another run time change we made was to remove the support we planned for the shelf which gave the table a more unique ad elegant look.
