Downdraft Sanding Cabinet Pt 4

Tuesday, January 10th, 2012

Whew, the holidays are over! Don’t get me wrong, I enjoyed mine, and hope you enjoyed yours too, but all that partying and visiting really cuts into the shop time. I will admit to not getting as far as I would have liked with the Downdraft Sanding Center over the last few weeks, but I did manage to get wheels mounted and the doors ready to mount.

For this project, I chose some better quality casters. I am not so concerned about the weight rating, even four cheap casters at 150 lbs each will handle more than I can lift onto the table. But a sanding center will vibrate a lot and certainly will be pushed from side to side as we sand the edges of parts and such. So I wanted to use casters that locked not only the wheel, but also the swivel. I got a set of four with 1/2″ dia threaded studs for about $40.00

 

 

The stud was not long enough to reach all the way through the base frame, so I counter bored the holes and secured them. This was done before finally attaching the base frame. Now the cabinet is complete and can be easily moved around as I continue work. I have avoided building the top because all of this work on the cabinet is a lot easier without the big top.

The final step on the cabinet itself is to make and attach the doors. The doors are frame and pegboard panel, and are built exactly like the sides and back of the cabinet were, but with thinner stock.

 

I milled the stock at 3/4″ thick and used the same stub tenon technique to glue them together. A couple pair of simple hinges are all that is needed to hang the doors. In the next installment, we will create the “egg crate” structure that makes up the center of the torsion box top.

Building the Sanding Center Pt 2

Thursday, November 3rd, 2011

 

In the last blog post we got the cabinet sides attached to the back. If you are building along, you’ll have noticed that this sub-assembly is pretty flimsy, so it is time to add a top and bottom deck to secure the parts and finish up the cabinet.

The material used here is not really important, the top will be covered by the torsion box that will be the downdraft sanding area, and the bottom is nothing more than a fixed shelf since the castors will be fixed to a 2×4 frame. I used a piece of scrap OSB for the top (the hole in the center serves no purpose, it was in the scrap) and the bottom was a piece of 3/4 birch ply I had. It just looks nicer than the OSB.

 

 

 These parts could be nailed or screwed through from the outside of the panels, but I chose to pocket screw them. Yes, it is just a work station, but I like things to look as nice as possible. For me, it is just more pleasant to use tools that look as good as they operate. Carefully measure your box opening and cut the panels to size, then drill the pockets and screw the parts together.

You’ll notice that I am using a clamp here. The point of a screw tends to separate parts a little before it grabs and pulls them back together. Since pocket screws go in at an angle, they tend to pull along the angle, mis-aligning the joint. clampint the joint prevents the initial separation, and the join remains where you placed it.

 

 

The same process is used to secure the bottom. If we were planning to attach casters directly to the bottom deck, then I probably would not trust the screws to hold since the deck is inside the box. This is a work station, and we can assume that it will see a lot of force pushing downward as we work. But since the top will overhang the cabinet, I want to casters to extend beyond the cabinet for stability, so we will be creating a frame under the cabinet to secure the casters. The entire box will rest on top of this frame so everything will be well supported. In the next post, we will assemble the frame and secure it to the box.
