I designed and built this jig for a “tablesaw and router” woodworking friend. I know what it is like to achive a true “45” with these tools. I made this for a mini sled but you could attach it to an existing sled that you already have. Does it work? YES!  I hope that this shared project helps and encourages you.

Test Cut 4” cube. I started with 6 pieces- MDF cut precisely on the CNC to exactly 4.00” – All 6 pieces were cut 45 degree on all 4 sides. Final measurement was 3.75” with a loss of .25” (start to finish)

The idea for my “project” comes from a web unknown, which inspired me to do this one,

Looks to be a very handy tool; requiring no set up time, after initial fabrication.

Great work, I am sure many will copy it.

I had this on mind when used non tilted home made tablesaw – nice and practical jig. Luckily I don’t need it now.

That would come in handy in any shop. Nice job!

I consider getting ‘perfect’ 45’s a strange mix of magic and skill. You can dial in the saw perfectly, but there still are errors that creep in from flexing of the miter gauge and problems holding everything tight and still.

Your jig solves the entire set of problems between the blade angle and saw operator, well done!

I like this a lot. It can be adapted to any sled. It’s the same idea another LJer posted for a tenoning jig on their sled. Excellent!

I made need to make one of these. I was cutting a 45 bevel on a small piece and it jammed against the fence and was thrown from the saw. I spent the last two nights re-aligning my saw arbor and had to buy a new blade since the old one was bent in the incident.

How did you dial in the 45?

Jim- The tablesaw works great at 45 when the piece is a “one cut larger piece”, for instance the 3 pieces of the sled base (14×14”) with one side a 45. Smaller pieces I used to cut on the CNC- Now I have the option of both the 45 sled or the CNC. I feel that the sled will be beneficial in preventing the mishaps that you shared above.

I’m sorry,

I don’t understand your responce. I would also like to no how you dialed in the jig to cut exactly 45.

I made one of these a year ago, but would not cut exactly 45, close but no cigar.

Can it be done without a cnc?

The jig will cut the angle that you make, be it a CNC or Saw. If using a saw make sure and test set up the angle- here is a link that might be of help http://woodworking.stackexchange.com/questions/3462/how-do-i-cut-a-45-degree-bevel-on-a-table-saw-with-consistent-dimensions
