Introduction: Make a Shop Vac Adapter
I could not find a suitable adapter to hook up my shop vac to my new table saw. So I decided to make one my self out of wood.
Step 1: I Need a Shop Vac Adapter
The 35mm hose of my shop vac is much smaller than the connector at the table saw. Since I could not find a suitable adapter I decided to build one myself. The idea is to cut out two circels one with the diameter of the shop vac hose and one with the diameter of the table saw connector. In between this two layers I'm going to cut out two tappered circels to bridge the gap between the two other circles.
Step 2: Preparing the Wood
I am using scraps of 3 layer panels which are 27mm thick. The diameters of the shop vac hose and the table saw connector are transfered directly to the wood. For the tappered cuts I had to find the correct angle. After writing down all the measurements I used the tangent function and found that I have to set the scroll saw to an angle of 14°. An other possibility would be to make an exact plan and measure the angle with a protractor.
Step 3: Cutting Out the Circles
After drilling a start hole into all the layers, I can cut out the circles on the scroll saw. To get the right dimension for the second tappered circle, I have to wait until the first tappered circle is cut. Once this is done it can be transfered from the first one.
Step 4: Sand and Glue
Now it's time to sand the inner parts. It doesn't have to be perfect but it will help the airflow if there are no rough spots.
Once this is done the 4 layers are laminated together.
Step 5: Make a Nice Round Adapter
This would already work. But the glued up square pieces lock very bulcky. So I decided to draw an outer circle, set the band saw table to a suitable angle and cut away most of the material to get a round adapter. Finally I sanded it on the beltsander. Since this is just to make it lock nicer I eyeballed all this measurements.
Step 6: Paint and Use
To look it nicer I painted it red.
The adpater works perfect. I already made a second one for my table saw, where I had the same problem.
We have a be nice policy.
