Time to Build Some Shop Cabinets

[Sam Chambers]

Well, I'm almost ready to build some much needed cabinets for the shop. I've never built any kind of cabinet before, so this will be a learning experience. I bought one of Danny Proulx's books and found some designs that I like.

And now come the questions:

- He made his out of 5/8" melamine, but I'm limited to 3/4". (I'll buy the stuff using a bunch of accumulated Borg gift cards, that's why!) Will 3/4" be sturdy enough?

- I might go with MDF instead of melamine, just for the base cabinets, because of their extra weight. Plywood is porbably not an option, because the good stuff is out of my price range.

- What's the best way to join MDF or melamine? Dados & glue? Biscuits & glue? Pocket Screws (with or without glue)? Confirmat screws? Something else?

Thanks!

3/4" is thicker than 5/8"...so I suspect you'll be fine.

Confirmat screws are the defacto standard for working with mechanical fasteners and these materials. I don't recommend pocket screws for MDF or Melamine (which is particle board with a pretty face). Glue and dados is fine, but for the melemine RooGlue is what you'll need to "stick" to the white stuff.

Menards, my local BORG of choice (although we do have a BORG) has three grades of 3/4" birch plywood, $25/4X8 sheet, ~$40/sheet and ~$75/sheet. I stay away from the $25/sheet, but the $40/sheet is what I use for shop cabinets. It is pretty good quality, and does not delaminate like the $25/sheet ply. They also have Oak available as well. HD or Lowe's should have the Oak ply as well, but generally do a poor job of stacking and supporting, which results in sheets of ply that is wavy and twisted. As Jim B. said, I wouldn't use the pocket screws with melamine, particle board or MDF, but with the ply the pocket screws would be fast and also have great holding power. I built my shop cabinets out of the oak ply about 8 years ago and they are still holding up great. Hope this helps. Regards, Bill

BTW, we had a new local woodworker's store open up and their plywood prices are only a few dollars more than the BORG, and the handling of the material, by the store, means that you will get good pieces of ply, so it is worth the money. I have bought my ply from them recently and have been very happy. So check out the local small woodworker's store first and give them your support if possible.

I have 3/4" MDF cabinets that have stood the trials without complaint. Dado and glue or dado, rabbet, glue and screws depending on function. Switched to 1/2" BB ply for the drawer bodies and used MDF false fronts to preserve the look and feel. I even used MDF with bridle joints for door frames but another material would probably be better.

DOH!!!

You'd think the accountant would remember his fractions!

I noticed that Titebond makes a melamine glue. How does it compare with RooGlue?

I've built and installed a ton of kitchens with both 5/8 and 3/4 mealmine boxes. As much as I hate the stuff, it is a really great material to work with if you want to build quick square and sturdy boxes.

Melamine tends to blow out, or shatter, but you can minimize this tendency. There are a couple of "tricks"

1. Predrill you screws
2. Use a real Particle core screw
3. Don't over torque your screws/ Use a cordless drill if you can. You can use a corded drill but you have to be carefull that one the screw is set, don't over tighten it. Lots of times I have to back out the first screw I sank and the reinistall a fresh new one.

For "BOXES", I don't really like MDF, maybe because it isn't finished in the same way that melamine is, but to be honest, I haven't really built enough boxes out of it to say beter.I've used melamine to build most of my shop cabinets and none are falling apart, they're still square and the still look fine. I like the prefinished melamine advantage, but I don't think it really makes that much diference what you choose.

I am a shop cabinet rookie myself, having only built the NYW router table with MDF and plywood. Around here (at Home Depot), there is a six buck difference in the price between 3/4 MDF and a paintable grade birch plywood (color variance). I like MDF OK once it is assembled. It is heavy and finishes well. What I don't like about it is the edges and corners are far more delicate than plywood during construction. It's an annoyance, along with the huge quantities of cutting and machining dust. I have to cut it out in the garage. Maybe I would like MDF more if it wasn't -7 outside today?

I don't know what others feel, but I think the Titebond melamine glue STINKS. It's like water. Very difficult to work with.

Rooglue is harder to get and more $$, but worth it.

Sam. I recently was in the same boat. Needing to build shop cabinets/bench space. Now it would not be a problem for me to build a set of cabinets (being a trim carpenter for years) but here's what I ended up doing.

search for "Small gloat... finnally setting up a real shop after years! " on woodnet

Maybe not as pleasing on the eye but it was cheaper and took a whole lot less time than building from scratch. I'm sure you would have a Restore in your area. http://www.habitat.org/cd/env/restor....aspx?place=87
Besides you're helping a good cause. P.S....they will deal with you on prices. WDO

I built my shop cabinets out of MDF for the carcass. I took Jim's advise 2 years ago and bought the confirmant screws and the drill bit. Get a good square to help line of the panels, drill and screw it together. Works great!

Because I deal with some machining and metal work, which can be both heavy and oily, I've found MDF hasn't worked for me, plus it doesn't support much weight unless supported.
Liquids are not MDF's friend, and some seem to seep though even paint and that will ruin MDF, personally I use plywood now, for the garage I buy the $28 stuff at Menard's and it ain't pretty, but it works.
Plus a coat or two of paint makes it look a lot better....

Have the same opinion of particle board also.

I have melamine kit cabinets in my shop that are now over 13 years old. Not a single problem in that time. I bought the kits at Home Depot - mostly Mills Pride white kitchen cabinets. I chose kits because of time factors and also because I could buy the materials for what the kits cost.

If you want to make your own, confirmat screws from McFeely's are excellent for melamine or MDF butt joints. Dado and glue works well too, although butt joints are strong enough for cabinet carcasses and a lot faster than clamp and glue joints.

[Jeffrey Makiel]

I second Dave's recommendation. One could purchase Mills Pride cabinets cheaper than buying, making and finishing your own. Unless you have some unique size requirement, this is a quick and easy option. You can also just buy the carcass and make your own doors too. The carcasses are available with a fake birch grain finish, or a white melamine finish.

I have found these cabinets to be sturdy and square upon assembly.

Cheers,
-Jeff

Another option for shop wall cabinents i(f you aren't using them as a learning experience) is to go down to habitat for humanity and get some used kitchen wall cabinents. Especially if you are willing to take odds and ends (unmatched singles), they are very inexpensive. The downside is that obviously there's no guarantee of what they have in stock on any given day.

[Jim Becker]

Buying knock down or used is certainly an option for "shop cabinets", especially when time is a major factor. But I encourage building them otherwise as it's an excellent chance to learn new techniques or experiment with different materials before you employ them on other projects for outside of the shop. I'm about as time-limited as most working/parenting woodworkers can get, but I still try to build my shop fixtures and cabinets when it's possible to do so. In fact, I'm about to do a rolling tool cabinet, both to accommodate my growing collection of Neander tools as well as to try out a few things I may use for the cabinetry in our addition.
