super-structure

I almost made through August with­out post­ing about a project. Then again, I almost made it through­out August with­out actu­al­ly com­plet­ing a project, as well.

I decid­ed to get around to a project I’d been want­i­ng to do for a few years now: a cart for my drill press. This is part of the big­ger project to revamp my garage shop and, even­tu­al­ly, clean up the garage as a whole. I start­ed by tear­ing our an old work­bench and putting my band­saw and pow­er sander on a cart. That bench was also where my drill press resided since I first got it and it had been moved to my main bench (along with all the oth­er junk in my garage it seems). So the idea would be to make a rel­a­tive­ly small cart with some draw­ers and stor­age for “drill” relat­ed items. I’m pret­ty pleased with how every­thing turned out, espe­cial­ly since there were a few new skills on this one.

First, I decid­ed I’d mod­el the project in CAD so I could make sure every­thing fit. I would be mak­ing draw­ers on slides for the first time, so I fig­ured it was impor­tant to get the mea­sure­ments right. I end­ed up using SketchUp since they have a free ver­sion for mak­ers (that runs on the Mac). It’s a pret­ty nice pro­gram and I fig­ured out to mod­el my project as well as gen­er­ate a cut sheet.

This morn­ing I got to actu­al­ly cut­ting and assem­bling. The cab­i­net for the cart isn’t espe­cial­ly large, but almost every­thing was larg­er than I could actu­al­ly cut on my table saw. So I had to break down most of the pieces using my cir­cu­lar saw and my home­made track. It’s a more tedious set­up and it has the draw­back of not being able to make repeat cuts. I man­aged to make a pass­ably square cab­i­net car­cass. My assem­bly jigs came in handy get­ting the car­cass togeth­er, too. I used pock­et holes and glue.

I also fol­lowed April Wilk­er­son­’s advice and glued up a dou­ble-thick top (1.5″ total of ply­wood as the entire cab­i­net is 3/4″ maple ply­wood) as the drill press is heavy and will cause long-term sag­ging if not well sup­port­ed. I dif­fered from her cart as a inten­tion­al­ly had the sides butt onto the top and bot­tom such that the pock­et hole / glue joint isn’t in direct shear from the load. It exposed the pock­et holes in the low­er cab­i­net open­ing, but no one in the garage is going to com­plain. This also allowed me to place the cas­tor at the very cor­ners of the bot­tom shelf with­out con­cern of the lag screws split­ting the sides.

I had an exist­ing piece of 1/4″ birch ply­wood that I used for the back pan­el. Before attach­ing it, I added in the divider which is hid­den by the bot­tom draw­er. This goes to add a bit of sta­bil­i­ty to the cart and also helped in installed the draw­ers. I used a trim router bit to clean up the 1/4″ back as it was just slight­ly wider than my 16″ width. The car­cass was just a bit off square, but I was able to nudge it just a bit when screw­ing on the back such that it trued up. That’s where tak­ing some time with the main butt / pock­et hole joints paid off.

While the wipe-on poly was cur­ing on the main cab­i­net, I got to work on the draw­ers. I used Brad Rodriguez’ gen­er­al design for the draw­ers. Once I broke down the 1/2″ birch ply­wood into two pieces, I could final­ly batch out the draw­er pieces on the table saw. I set up the fence to rip the false fronts and the moved the fence again to rip the 4″ draw­er sides. I made sure to place the draw­er slides and sides into the cab­i­net open­ing to mea­sure for the width. I could then use my cross-cut sled to get my final pieces. Of course for the 1/4″ ply­wood draw­er bot­toms, I still need­ed to use the cir­cu­lar saw. I assem­bled the draw­ers with pock­et holes (laid out such that they’ll be hid­den once in place. You may notice that I did­n’t use draw­er pulls but went with just notched han­dles (again, some­what inspired by April Wilk­er­son here along with some of our IKEA draw­ers). This coin­ci­den­tal­ly allowed me to eas­i­ly clamp on the false fronts while get­ting them attached. I used the band saw to cut out the notch­es and then the pow­er sander just to clean things up and get right up to my lines (and I should add that hav­ing those on a cart is also great!).

Get­ting the draw­er slides installed was pret­ty straight for­ward, although I man­aged to get the spac­ing off some. Noth­ing crit­i­cal, just that the slides are at dif­fer­ent depths on the top ver­sus bot­tom draw­er. As of right now, the draw­ers are only held togeth­er with the pock­et holes and 5/8″ screws for the bot­toms. I did this to “dry fit” them as I was­n’t 100% sure they’d fit in the slides (it’s tight to be for sure). If they don’t bind up as I use them, I’ll prob­a­bly take them back apart and glue them togeth­er. I prob­a­bly would have done so today, but this “small” project end­ed up tak­ing me over 8 hours so I just swept up the garage and called it a day. The good news is that I had some addi­tion­al stor­age to put things away when clean­ing up that I did­n’t have this morn­ing!
