Made with the Laser Engraver...

I had a need to cut multiple dowels and didn't have access to the table saw right away.

I drew a simple sled - a foundation design for more enhancements and sizes - which I could burn and assemble with glue.

I built this at TechShop San Jose - www.techshop.ws

Step 1: Hello MDF, My Old Friend...


It's made from 1/4" MDF - one of my favorites for laser cutting and assembling.  Great for Jigs! Cheap!

The height of the fence is 1/4" in this case - this was enough to address the 1/4" dowels I needed to cut.  I can easily upgrade this to a higher fence/sled for larger stock - 1/2" dowels, for example.

Step 2: Cut the Pieces...

I designed it with a slew of mortise / tenon pairs to make it easy to align the sled pieces.  If the laser burns hot, you can still get a nice 90degree fence with the alignment help these provide.

I hadn't thought of it, but this fence could be easily modified to cut at various angles.

Here's the Corel Draw 5 file for the pieces.  I won't put power/speed settings here - those'll vary with the laser.

Step 3: Then Assemble Them...

The tenons are mostly the same.  The one on the front of the sled base has a wedge, as does the one at the rear of the sled base - where they attach the runner to the sled.  This keeps us from having sharp edges.

I used a bit of yellow glue and clamped-up the pieces.

Step 4: And Keep Your Fingers Safer...


I estimate it cost about 15 cents for all the mdf - very cheap indeed.  It's easy enough to make this out of scraps.

REMEMBER!
Careful when you cut the dowels - do NOT pull the sled back through the band saw blade to prevent pulling the blade out of alignment or off its track / wheel.

Since it's so cheap, cutting all the way through the sled is fine, if it fits your needs.
Very interesting! Dumb question: I don't get the black markers........are those just measurement markers??
I used a bunch of them just to assure alignment between the runner, sled base, and fence. <br><br>Often, folks will cut the end of the sled off and I wanted to make sure there were still plenty of tenons left if this was done.<br><br>
Hiya.<br><br>When the laser cuts through the MDF, it burns the wood. The dark 'markers' are the tenons that are cut out.<br><br>The MDF is 1/4&quot;, and the tenon width is 1/2&quot;. I turn them on their sides to insert them between the sled base and fence.<br><br>Make sense? If not, I'll make sure to show assembly details next time.
This is a good idea, are you willing to share your vector file with your post?
Okay. I've added the vector file now...
Oops! Will do that a bit later today. <br>
It looks great but you can clamp a scrap board to the saw's miter guide for the same effect and you get the added bonus of angle adjustment.
