AAAHHHH...someone said harbor freight and  Chicago Electric. stay away from both. Cheap, shoddily made, garbage.  If you are going to buy tools you want to last,  buy good ones.....in this case you DO get what you pay for.”

 

AGAIN with the equipment snobbery and this stupid notion that if it’s less expensive (be it tools, or sound equipment, or lighting, etc.) it’s not worth your consideration.  Just like everything out there, there are heavy duty, professional grade tools for people “in the business” and there are tools designed more for the “weekend warrior.”  And there is the out-and-out junk.  NO MANUFACTURER IS EXCLUSIVELY IN ONE CAMP.  The challenge is to discern which are worthwhile in EVERY manufacturer’s inventory.  I have used inexpensive Harbor Freight (yes, Chicago Electric) tools for YEARS with no problems, and PROFESSIONAL grade Ryobi and DeWalt tools with tremendous problems, and very over-priced junk from Rockler Tools.  For me to make a blanket statement about these manufacturers, based on my experiences in these cases would be equally stupid.  They ALL make equipment that is USUALLY very good when applied to their intended use.

 

Matching the USE with the tool is more prudent than blindly buying a brand name, regardless of intended use.  I often say people who buy over-priced equipment because of the NAME (and not the actual design/construction of the piece and how well it would work with the intended use) are an advertiser’s dream.  Sure, purchasing the “Rolls Royce” version of a tool would be nice, but terribly inappropriate for the person looking to merely “go-kart.”  So what’s the difference between a $25.00 Chicago Electric circular saw and a $320.00 Makita professional grade saw?  Plenty, but most of it is totally wasted on a guy with a limited budget, cutting 1/8 inch luan to build flats.  And the longer life expected from the more expensive tool is never a sure thing (and since when has ANY tool lasted for twenty years, trouble free with the abuse at a community theatre?)

 

A far smarter approach is to educate yourself on what to look for in a tool, and how well it is designed for the use intended.  Get on the Internet and check out how well a manufacturer stands behind their product, steering clear of the “only buy this because everything else is junk” comments from prejudiced equipment snobs.  Then go pick the tool up, hold it in your hands, look it over, read the specs, consider the warranty, AND CONSIDER THE PRICE.  Put the shoddy stuff back on the shelf, but consider the rest.  The top of the line is not always the best choice; it can sometimes be a serious waste of money.

Yes a circular saw in the arsenal would be very nice. Especially one with a lazer sight - My new powered mitre box has one and I love it. But for this conversation I think a circular saw would just be the same mistake only faster.

The nephew and I tried Topper's trick with screwing the brace down every 16" but sadly hit the same snag - the saw worked it's way under the brace. This time though the brace had enough force to stop the saw in its tracks which let me know my line was drifting.

I think this weekend we'll try it again but reduce the gap to 10" per screw and see if that does the trick.

Thanks for all your help and suggestions everybody - and keep'em coming :)

Will.
 
Are you putting anything under plywood for support? In my theatre I can hand the plywood off the edge of the stage so that the straight edge is over the stage, but the cut line is off of it. In this way you have no worry of sag.
 
You could achieve the same thing with a couple 2x4s. Find two nice straight 2x4s put one under the plywood up on edge and the other on top of it so the plywood is sandwiched between them. You can then screw the two together to hold everything is place. Putting the bottom one up on edge should give you enough clearence so that the jig saw blade doesn't hit the floor underneath (be sure to check it first). If you want to avoid the holes you could even use 12's 2x4s and screw them together beyond the edges of the piece you are cutting.

I totally agree with Spectrum's comments. I do a lot of set construction and a do carpentry as a hobby and I am a big fan of Harbour Freight. I am fortune enough to live within driving distance of one of thier stores and this is made better by that fact that it's in an econmic re-development zone so I pay 1/2 normal sales tax.
 
There are certain items there that I wouldn't buy, you can just feel that they are cheap and not worth buying, but pretty much everything I have bought I have been happy with. In some cases thier items are so inexpensive that I don't care if they only last a year or two. It's cheaper to buy a new one every couple years then to but a more expensive item to start with. I purchased a pneumatic nail gun there a while back for under $20.00. It works great and for that price I don't care if I have to replace it in a couple years.

Likewise, I needed a hammer drill for a project (drilling into concrete) and since I thought it was going to be one-time thing, I purchased an VERY inexpensive off-brand store model from Sears, thinking "what the heck -- I only need it once, who cares if it falls apart afterwards?."

Eight years later, the thing is still going strong and I've been finding dozens of different uses for it since. In fact, I can't wait until it finally quits on me because I've been so careless with it, it's pretty messed up and I plan to buy a spiffy new one.

Topper go & treat yourself to a new fangled drill!
[But frame the old one on the wall - it might come in handy, when the new falls apart]Wink
 
Will  - instead of messing about with a jigsaw, just use a good hand ripsaw. You can control the cut better & at least it should be straighter!

This topic is way old at this point but I do want to post an update. I found a solution that works for me and I wanted to share it.

It's a laminate trim bit for my router. One of my set books made brief mention of it for lauan covered flats and now I'm in love.

In brief you simply cut the plywood with the jigsaw - wavy lines and all. Just make sure the wood is a just a little bigger than necessary (I gun for an 8th of an inch). When it's cut I then clamp the piece to my work table and run the laminate trim bit around the edges. A little sanding later and it's the straightest line I've ever seen!

If anyone needs more detail let me know and I'll gladly share.

P.s. as part of the tool debate I predominantly use Skil equipment and have never regretted it. My mitre saw is a Task Force and it's never let me down either. None of them were very expensive.

I tend to buy Craftsman for no good reason except that my dad bought Craftsman. Lately I have been using their 19.2 volt tools. I have the hammer drill, and the trim saw (it has a laser). I tried the stapler, but didn't like it and took it back. They have a laminate trimmer too, but I have not tried it. I have used the Straight Cut with success, but you do need to support.
 
One very obvious solution that most of us overlook is to have the store cut it for you. Home Depot has a wonderful panel-saw and they are happy to make the cuts for you. It can make the stuff much easier to carry too.
 
I like the laminate trimmer idea. Unfortunately we build in 4' multiples so we use the whole sheet. It might be a great tool for cutting out windows though.

I too use the whole sheet for flats but will still pass the trim bit around it just to gaurantee everything is flush and straight. Sometime you get a corner that sticks out a bit and makes joining flats a pain in the but.

It's great for window cuts and tabletops especially!

When I make a non-standard sized flat, I ensure that the frame of the flat which supports the facing material is accurate, and then glue and staple the facing material to the frame. To make a perfect, smooth edge to the flat, use a router. Use a trim bit. This is where it is worth spending more money. Get a trim bit with three cutting edges, instead of the usual two if you can.

This is also by far the best way to make window and door flats. Drill a hole large enough for the router bit in the facing material in the part that will be open, and route the facing material right to the edge of the opening.

Someone asked how to fill screw and staple holes in the flats. Use drywall joint compound. It is a lot cheaper than wood putty, and can be sanded perfectly smooth far more easily.

I realize this is an old thread but I see the last post was just a month or so ago. Anyway, here is my two cents.
 
If you have a circular saw, the lines still end up a little uneven unless you make a jig. The jig I am talking about is one that a theater prop director showed me once. Take a straight 1x3 board and glue it to the edge of a piece of 1/4th inch plywood. Let the glue dry completely then take your circular saw and cut the plywood with the edge of the saw guard against the 1x3. This gives you a straight edge exactly where the blade will cut to line up on your project. Simply clamp the jig to the project with the edge of the plywood right on your line you need cut and the blade will follow. Also, the blade will not be able to work it's way under the jig because the flat surface of the guard slides right along the plywood.
 
Hope this helps someone out.
