Router Table – The Cabinet

Published on by Mike  (Leave a comment)

Okay, so I am going a little out-of-order from how I am building the table.  The fence is mostly done, but I am still working on tweaks.  I only want to do one post on the fence so i will publish that post once I am happy with how the fence is performing.

In the meantime, I can write about the cabinet.  It’s not done yet.  🙂  However it is to a point that it is useable.  What I have left is the drawers, the door, the back, and dust collection.  Those will be discussed in a future post.

cabinet_gluedThe cabinet is largely made from birch plywood from a big box store.  I drew a rough sketchup drawing so I could get an idea of how much plywood I would need.  Turned out I needed a sheet and a half.  I went ahead and bought two full sheets.   Always good to have extra on hand.  I went with ~3/4″ thick ply for its strength.

The primary joinery is dado and rabbets.  Normally I would leave it at that and just clamp it up.  however, it is a shop project so I also used screws and nails.  With the size of the cabinet, it made it easier to square up and hold together while the glue dried.

edge_bandedI decided against a face frame.  I wanted to maximize the storage potential of the cabinet.  After the glue dried I edge banded all the front facing plywood edges with a hardwood.  This is largely so I don’t have to look at the plywood edges every day.  🙂  I fitted each piece individually, and just simply glue and nailed each one in place.  (Hey it is a shop project after all!)

One of the goals I had with the cabinet is that, like my hand tool cabinet, I wanted it to be able to change it as my needs changed.  I have actually designed that I can change the height of the table.  That way if I ever have a need to match the height to a bench or other machine, I can do so with minimal modification.  The space between the cabinet and the top can be changed out.  It also has a lot of support to help keep the top flat.  More of the flexibility will come as I build the drawers, and I will go into more detail once those are complete.  The back won’t be glued in, just simply screwed in.  This will help make modifications in the future easier.

The power setup for this was fairly straight forward.  I bought a power switch at a woodworking show.  I wanted a power cord that came out the back, and the cord that came with the switch wasn’t long enough.  After some playing around with the switch, I decided not to modify it in any way.  Instead I bought a replacement tool power cord, a junction box, and an electrical outlet.  I wired up the cord to the outlet, and put the junction box attached to the interior of the cabinet.  After using a tester to verify it is wired up correctly, I just simply plugged the switch into the outlet, and the plugged the router into the switch.

One of the things I hated about my previous router table was it wasn’t easy to move.  With a small shop, having the ability to move machines around is vital.  So the bottom of the cabinet is held up by casters.

router_tableFinally, the top simply sits on top of the table.  There are blocks that hold the table in place laterally, but it just simply uses gravity to hold it in place.  I made sure that there was no lateral movement (side to side and front to back) at all.

Despite the unfinished state of the cabinet, it is complete enough that it is now a functioning router table!  I will write a full review of the lift, but I can say my initial impressions of it are great!

 

Router Table – Making The Top

Published on by Mike  (Leave a comment)

Now that the shop has finally been warm enough I have been able to work more on the router.  Therefore, I am now able to write about my progress!

The top is composed of two layers of MDF edge banded with some left over hardwood, and a layer of Formica across the top.  I will ask my readers to take extra care while building a top like this, as it does get heavy, and MDF creates a LOT of dust when being cut.  I actually tend to avoid using MDF as much as possible, but with the flatness and weight it is perfect for a router table top.

grid_layoutThe first step in making the top is cutting the two sheets of MDF, so that they are over-sized.  I have learned the hard way that laminating two sheets of MDF never go together right on, so making them over-sized will allow for trimming later in.  On one of the pieces, I drew out a grid of lines to determine placement of the screws so that they would not get hit by a bit or blade when cutting out the inserts for the lift and track.  I then drill and counter sink for all the screws.  With that done, I spread a ton of glue across the first layer of MDF, keeping it as even as possible.  I then place the two layers together, and then start feeding screws in, working from the center out, until all are in.  since I had some sections void of screws, I also used clamps and weight to hold the two sheets together until the glue dried.

Once the glue was dry, I was ready to trim the top to final dimensions.  Please be aware, the top is heavy.   I kept one edge as straight as possible so I could run it against the table saw fence and get one clean edge.  I then bring the fence to the final width I want and ripped the opposite side.  I did take care to make sure I took off about the same amount on both sides so that I could keep the lift centered.  I then cut a bit off of each end using the crosscut sled to get to the final length.

I will note, the top is heavy at this point.  I believe to do this safely on the table saw a good heavy saw with a crosscut sled is needed.  If you don’t have either or both of these, a circular saw with a good blade, and a guide rail can do just as good a job.

edge_bandingFor the edge banding, I milled up some 3/4″ stock and cut miters for each corner, taking care to fit each one individually.  I actually chose not to drive any nails, and just simply clamped them in place.  After the glue dried, I then used a hand plan and card scraper to make sure that the edge banding was absolutely flush to the MDF top.  I also eased the corners so that they were not too sharp.

formica_installedThe top was ready for the Formica layer.  For this I used contact cement, sprayed on both the top and Formica.  Once tacky I put down the Formica on to the top, and used a j-roller to smooth it out.  I then used a flush trim router bit to get the Formica perfectly fitted, and finally another pass with a chamfer bit to ease the edges.

recess_routedUsing templates I made (will discuss making those in a future post) and spiral router bit with a template bushing, I routed out the recess for the lift’s plate.  I actually left a center section in that I used as template to route down as far as I could with the bit I have.  I then cut out the remaining depth with my handheld jigsaw.  Since the method left a lip, I was able to clean the cut up with a flush trim bit.  I then fitted and leveled the lift into the recess.

track_routeThe last piece for the top was to get the combo track installed.  I actually used the guides on the lift plate to help position my guide rail so that it was parallel to the front of the table, and that my 3/4″ router bit came close to touching the plate.  This would not be moved again for any of the passes to route out the channel.  First, I clamped the combo track against the guide rail which established the edge closest to the front.  I then routed out the first pass, which left a 3/4″ groove.  I then removed the track, and used the t-track clamped against the guide rail.  This established the edge furthest away from front of the table, and perfectly set the width for the combo track.  All that was left was a row between the first two passes, which I cleaned that out as well.  The track is held in place with bolts.  Once it was installed, I shaved down the edges so that they matched the chamfered edges.

top_doneWith that, the top is complete.
