All,
I hate to bother y’all agan with another basic question but being a novice at ww I easily get perplexed. I want to make the bench-top bench shown in this months (Mar-April) FWW. So I purchased a 7″ wide piece of maple 10′ in length and 1 3/4″ thick. This should provide enough material if I rip the piece in half. Now for my question: Should I rip the wood first then cut to length the needed pieces or cross cut at a predetermined length (determined by the parts needed) then rip the cross cut piece? I don’t want to make a mess of things because the wood is SO expensive.
Thanks,
dlb
p.s. the base will be maple and the top will be red oak.

dlb..
the best solution will depend on your shop space... do you have enough space to rip a board that length??
Personally, I don't; I'd have no option but to cross-cut ASAP to make the pieces more manageable..
If you don't have one already, make a cut-list, study the pieces and see which makes the most eficient use of your set up....

Stay safe....Have fun
I tend to agree with Mike, and I have plenty ofroom for long rip in my shop.
I cut to length and then rip because long ripped boards tend to twist and bow more than shorter ones, depending on grain. The shorter boards do so less, and are easier to joint, as well as thickness plane..
BTW I don't post here much. I lurk a lot and contribute what I can, mostly over in Breaktime

Dlb,
I just finished building the mini-workbench, it's fun. If you can get the board home in one piece, the first thing to do is take a piece of chalk and, roughly, layout the parts on the board. Usually, I can't put a board that long in the car so I have them crosscut a chunk that'll represent a couple of parts....like maybe cross cut 50" for the top...so I come home with a 4'+ piece and a 6' piece

I am making the benchtop bench so I can exercise my skills in ww & so I can get some experience so that when I make a full sized bench I will feel more comfortable. Glad to hear that your went well. I look forward to completing mine.

BG,
When you made your top did you use any kind of joinery prior to gluing? I was wondering if I needed to use some dowels, a spline, ... . My top is going to be make of red oak.
Thanks,

Dlb, a well jointed edge and plain old Titebond will do just fine.
I have made or overseen the production of literally thousands of solid case good parts and table tops using that method, and never had a joint failure in the field. As part of quality control, we did a fair amount of destructive testing and found that the tops very rarely broke on a glue joint, but almost always through untouched wood. Even when part of a break was on the joint, most of the break still went through raw wood, indicating that the joint was stronger than the wood.
In my experience, biscuits and splines don't help that much with alignment, either. Staright boards and careful assembly take less time and actually produce better results for me than relying on biscuits or splines ever did.

dlb,
Woodwiz said it all and has lots more experience than I. However, I did make a couple of modifications that I think help the basic design. First, I made it a bit less tall for my own comfort on top of my workbench.(I'm 6'3") You don't have a workbench yet to guage that... Also, I put two dado's on the underside of the top that locks in the base structure. That allows me to let the top float(expand and contract) around the screws and still have a very solid feel to the top. Lastly, I put a 3/4" hole in the base feet/runners so I could drop a dog through to the workbench doghole for greater stability while in use.
You most definitely want to cross cut first, then rip. Add +1 inch to the cross cut length.
Reasons to xcut first are (1) if you have twist, warp, or bow (and you will) the amount is less over the shorter distance; and (2) it's easier to handle a short board when ripping than a long board.
You don't need to cross cut long boards on a table saw; a chop saw or even a circular saw are fine for making the initial rough (cross) cuts. Do the final cross cut once all the boards are glued up.
Good luck, and never be afraid to ask even the most basic of questions. That's what the board is all about!
Thanks for the advice. I didn't think about making a rough cut first with my circular saw then a finished cut on my ts. That is a great idea and it moves the worry concerning exactness from the initial stages of the project to the fininshing stages where you can concentrate more on exactness - I think I am correct about that.
Thanks again,
dlb

I may be too late but this is important....
Always rough cut fist and larger than the finished piece dimensions. All solid wood will move after cutting. It will twist, bend, warp, shrink, grow, end check, etc. Give it a couple of days to become stable prior to any finish cut.
dlb
a chunk of maple like that should cost you right around $20.00(I'm assuming all white hard maple FAS grade) please tell me that you didn't pay more than that.. if you did please ask and I'll tell you how to buy wood at those sort of prices..
If you did not get my e-mail send a test e-mail to me.
thenks,

Hi
Ripping a long board on a table saw can be tricky , if not dangerous in inexperienced hands.
Cross cut first, then rip.

Ps . Your local lumber merchant should have software that will set out a cost efficient cutting list
Dib, most of the previous posts make good sensEspecially prior crosscutting and a waiting period for the material to adjust to the ambient temperature/humidity
One caution however is not to expect the edges of the boards to be parallel even if your crosscuts are perpendicular.
Make all (Or most) of the initial crosscuts reasonably at 90 degs
Then joint (Or rip) all the left sides perfectly straight
Rip all jointed sections to finish width
Then, rip the remaining sections to size,
using the cut side against the fence
NOW set the sled/miter gauge to
exactly 90 deg and crosscut BOTH ends of each to finish size.

Thanks for the input. I will give the procedure a try. I was thinking the other evening about the fact that I need to establish a method by which I will aproach cutting lumber. Your's sounds like a very reasonable one.
