Default Help Squaring Up This block.

I'll start by saying that I feel really dumb asking this question, but I'm kinda stumped here and looking for some simple solutions. I've got a chunk of walnut that I'm trying to get all squared up.(see the diagram below). Sides A and B are flat and parallel to each other, I milled them using a router planer jig I made. Side C and D are not flat, and not parallel at all. How do I get C & D square to A&B? I can't run it through the table saw as is because I'm guessing I will just end up with more unsquareness. Any help would be greatly appreciated. This piece is about 2x3 or so.

Slap a square on it, with the top of the square sitting along edge A, so that you can draw up a straight line along edge C. Repeat for edge D. Cut along line. Or is this just way too simplistic?

Yes that is very simple, but if cutting this on the TS wouldn't a slanted side against the fence cause me to have an unsquare cut? I just don't want to screw this piece up so I'm thinking this through.

Could you make up a makeshift sled for your tablesaw? Mine isn't quite makeshift *L* but should give you the general idea. You can pretty much make one out of scraps, depending on what you might have on hand. the one pictured will handle pieces 24"s wide..

HTH..

I assume you don't have a jointer.

The table saw will work but you need to either attach a straight edhe to the workpiece, or attach the workpiece to a straightedge. The straightedge must be as long as the workpiece and will contact the fence. I have an 8ft guide I've used with doublesided tape. If you have a fresh sheet of plywood, or MDF, or something, you could cur off a 2, or 3 inch wide piece from one of the finished edges to make a pretty good straightedge.

Well I do have a cross cut sled, so I could probably use it. RJM, your idea is probably the most simple and effective. I've got some 1/8" hardboard and some 1/4" mdf that I could brad nail attach to one side and run it through.

I've been waiting all night for you to chime in Bj. What took you so long? Can you post another pic of that with a "test" piece in the jig. I need to see it set up. Please Even better, do you have some "plans" made up for this jig that I could *cough* borrow?

Hi Jake

Sorry no plans but you don't need one on this jig, just two 2" x 2" x 36" long boards (or rip a 2" x 4" board down the center) and a hinge on one end will do the trick and a small push block to push the stock by the saw blade, I do get carried away with jigs some times when I make them for me..the table saw scares the hell out of me so I put in safe guards, like the hold down adjustment block and the handles.

You can also just pickup one at Rockler or many wood working tool supply outlets.

I use it all the time when the stock I get looks like bow and arrow stock..it will true it up in one pass on the table saw, or I want to put a angle on the stock up to 45 deg. easy and true..

like below

You know, I don't blame you!! When I'm using my TS, I often think "what would happen if one of feet slipped and I lost my balance right now".

I'm starting to think that I should have a TS jig for any cut I would make on it. It seems like I've been making more jigs, fixtures, and clamp racks than actual projects but I think I'm going to stop and make that supersled I've been thinking about.

Thanks.
