BOM (Bill of Material) for plans?

[Knuckle Bones]

Hey all. I got my plans for the DR290 and I'm chomping at the bit to go with it! I'm reading through them now and will do that again a couple of times prior to start.

I don't see a BOM (Bill of Materials) anywhere. I'd like to make a single trip to Home Depot with a list of materials I'll need for construction at a minimum (also would be nice to have a list of recommended tools). Can anyone point me to a post on the forums that has this? If it's listed in the plans I apologize for overlooking but I don't think it is.

I'd like to make a single trip to Home Depot .

That would be a wasted trip, as the majority of what you need you won't find at Home Depot, leastways not in terms of plywood. Read the plans through five or six times, making notes of what you need as you do so, then start calling around to find what you need before wasting time and gas.

As soon as you make one up, please post it.

As far as I know, there isn't one. Sit down with paper and pencil and get to it. It's actually helpful to do it yourself anyway, it will familiarize you with the plans.

Here's a list of some items to get you thinkin'. You may or may not use all of them, and I'm sure I've missed something.

From supplier:
Corners
Feet
Handles
Input jacks
Crossover componenets
Wire
Dish plate
Bass driver
Compression driver
Horn lens
Screws for hardware
Carpet or duratex
Carpet adhesive

Locally:
Plywood of various types
PL adhesive
Screws, nails or brads depending on your weapon of choice
Hot melt glue and gun
Mattress topper
Poly stuffing
PVC pipe
T-nuts and bolts

Tools:
Circular Saw
Jigsaw
Sander. If you only get one, make it a random orbital.
Drill
Drill bits
Screwdriver bit
Clamps
Square
Compass or some way to draw an accurate circle
Something to set and check angles

Optional tools:
Band saw
Router and bits
Table saw
Air compressor and brad gun

BEER! (after you've finished using the tools, of course!)

Thanks Bill and Tim. Good point that coming up with one myself will help me get familiar with everything. Thanks Tim for the list, too. Especially on the tools. What I don't want to happen is me working away and suddenly need to make a trip to get something from Home Depot to make a particular cut, measurement, etc.

I have or have direct access to everything on that list as far as tools go so I'm feeling good about being covered on that front.

You're brave! It took me months and two other BFMD projects before I decided I was ready for a DR

I fully endorse the read through many times approach. As you think about it, you will see how right Bill is about not getting too much of what you need at HD.

There are three classes of things that go into a BFMD cab:

1) The stuff that you will want to get from Part's Express (PE) or other internet based outfitter (like Larry Langford, or BLTSound...)
From PE: Corners, x-over parts, feet, handles, foam "weather stripping", piezo tweeters, hurricane nuts, (tip: small black screws for corners and tweeters...and hex key bolts for drivers are cheap at PE). Larry for drivers.
Since shipping contributes to cost, as does bulk, you may want as complete a list as possible so that you only need to order once from PE.

2) The stuff you will get from a specialty lumber yard...which is to say most or ALL of the plywood that goes into your cab. You just have to find a place like this or order over the internet. (Good ones will have specialty screws too...but not as cheaply as what you can get at PE...so you may want to check there first.) HD and most Loews don't have what you'll need in any of the grades you'll need.

3) The stuff you can get from local box stores like HD or Ace or Lowes. This is the LEAST of your worries, since these places are everywhere. The other stuff is what you really need to inventory IMHO.

Thanks for the tips! I went to HD yesterday just to look and I actually found true birch 1/8 and 1/4 ply....not the thin top layer laminate stuff but actual equal thickness laminate ply. Also found the Arauco plywood which Bill has recommended as an alternative to Baltic Birch.

Where are you that you can find these things at HD!? Here in the Northern Caribbean, I can't find some of that stuff in specialty lumber yards!

Oy! The HD's AND the music is better than here

Portland, Oregon

1/2" 7 equal plys $33 for full sheets
3/4" 11 equal plys $40 for full sheets

I was pretty surprised to find it there. I had to pull out the glasses and double check.

Are those prices about normal? Didn't seem too bad considering what basic lumber costs these days.

I pay $28 for a 5x5 sheet of 1/2" baltic birch. The 4x8 sheets are permanently "not available" for the forseeable future, says the yard's supplier. Evidently the Chinese or somebody else is gobbling it all up at a higher price.

I'm using "American Birch" in 4x8 sheets at $33 per sheet. It ain't BB, but it seems to do the job OK. I have a T39 in build now using this plywood.

[bjhueni]

This stuff isn't labelled Baltic but it's pretty nice. Both surfaces are good with only small knots if any and I could not spot a void in any of the edges I checked. It was in the "cabinet" area. I was really surprised and pleased to find it at my local store.

I just wish the had the table saw I wanted there. I ended up grabbing the wrong one because it looked just like the one I wanted. I was going for a low end Ryobi for occaisional use and it turns out they changed the model. The website lists the old one, the store has a new one. The new one has an "improved" top that...

Has no guide slots!

So making a panel jig is out. I couldn't believe it. The fancy new miter system looks like a pain. I couldn't see a good way to make a jig so back it goes. I'm going to bite the bullet I think and get a Bosch. Whatever I get I'm going to be sure and look at more closely. If they don't have one set up we'll just crack it open. I felt pretty dumb last night when I opened it up and saw that.

If you're talking about the sliding table with the 12" long protractor, it's highly accurate. You can build a panel jig by using two guides that slide on the outside of the main table.

What I really don't like is the integrated rip fence rails on just about every table saw in the less than $400 price range. When my old saw died I had to search all about to find a $150 saw (that's all I need to cut 1/2 plywood) that I could mount my Biesemeyer fence to. Finally found a Delta.

[bjhueni]

Do you remove the handle on the left side? I thought about clamping down the extension and using a single 4" guide in that slot. The other problem I noticed was that the sliding portion was not flush to the table and it rocked a bit. I wasn't real mad at the maker/store. I just felt dumb for not being more careful in choosing it. I have other Ryobi stuff from HD that I'm pretty happy with. I don't use it for a living and it hasn't let me down round the house.
