Default Lock Miter Bit

Two questions, I purchased a Skill lock miter bit from Lowes despite the seven reviews on Lowes web site said they were not ground properly leaving a sloppey fit I figured it was operator error, I will try them out tommorow morning AFTER I read your posts did I buy a low quality bit? Question #2 help save me some set up time, I will set the center of the bit with the center of wood but where should I set the fence? Normaly I answer question not ask so I need a helping hand with this one.

Thank you Chris

After centering the bit lock in the stock, my starting point is to place 2 blocks same thickness as stock eitherside of bit. Place straight edge on blocks and against fence and slide till it touches bit fine tune from there

Check out the video at this web site, my preferred source of router bits:

Fence to centre of cutter.

Set up blocks get you close but not all 3/4" or 1/2" are created equally. Do set up blocks for a MLCS bit work with a SKILL Bit? And set block will not work with 4/4 stock or

If you use cl bit =face of fence the distance from long point to lock groove will not be equal on both pieces

The biggest key is milling the vertical piece without it "lowering" at the end of cut. (The bit is cutting the very end of stock) If there is a flat surface on top of your fence, clamp a block that will slide on the flat top to your stock so it will keep the vertical cut plumb and will not drop.

Hey Chris...

I picked up one of those Skill lock miters from Lowes a while back and found it to be useless on 3/4" stock. Turned out the bit was machined about 1/32nd short. Does a decent job on thinner stock, but forget it with 3/4. I turned to Sommerfields' bit with the easy setup jig and have never looked back. The setup jig "ISN"T" necessary, but it does serve for several different bits and I've found it to be quite handy to have around. Set up blocks you can make yourself serve the same purpose once you've nailed the setup on the table/bit....

It took about an hour to get right but when I got the bit set properly I made perfect lock miter joint on 3/4 pine. I would like to say all the negitive reviews on Lowes web sight were due to operator error but maby a better quality bit might not have gave me so much hell. I will keep my bit and I made a set up block I had a hard time believing skill would sell a bit that didn't work. I thank all of you for the help and to those of you who face the problem I had I say take your time on a set up some bits require a little more patients.
Thank you, Chris

I'm glad you got there in the end Chris, and I hope you saved set-up pieces for the next time.
