Stumpy Nubs Jig Contest-Sine plate for drill press

Here are some real handy jigs I use all the time in my shop. The first one is the sine plate for accurately drilling holes at and angle in flat or round stock. I use it a lot for repairing or making replacement chair legs.
They are not the best looking jigs but they are made from what I had in the wood bin at the time and cut accurately enough to do the job. They will get beat up so I don’t go for pretty in these.

The way it is made is that there are two V grooves in the top plate put at exactly 10” apart. Then I used two tubes of the same diameter to get mounted in the grooves. The one at the pivot point is spit into three pieces and the outer pieces turn around the center. The center is screwed to the base and the ends are screwed to the top plate. To use it to drill at an angle, find the sine of the angle and multiply by 10 and make that much shim for the end that raises. You can make a clamp for the side of it as I did, but I have found it works just fine without it. Made from old particle board tops.

The other jig is just a v block for holding round parts for drilling. I use it on the sine plate some times. Made it in the table saw from red Oak

The last one is an angle plate I use in the drill press all the time. You can put a round part in the corner and throw a clamp on it to stabilize it for drilling the end. It is set very square so you can depend on it. Made from Oak faced plywood.

Jim I use a similar old Vee block to knock the corners of square stock thru the bandsaw befiorwe turning, saves a lot of thump. thump on the arms.
Nice & simple jig

Those sure do look alot like tools I used when I was a machinist. I thought about the sine plate idea a while back but never got around to making it. Maybe one day soon.

Where would we be without our favorite jigs? These are great ideas Jim.

Thanks for sharing

Hi Doug. I was a tool maker decades ago and it gets in your blood! You always think in those terms and make tools that way once you’ve been in the trade, I think…..................Jim

Eddie- you are sitting in front of a huge calculator right now!

type this into google search engine-

sin 10 degrees *10

tells you—

= 1.73648178 is the spacer size you need to put under the tube. About 1 47/64”, if you do not have a digital calipers.

and yes, the tubes need to be the same.

Great jig. Couldn’t help but notice, but is that the Grizzly 14” Polar Bear series saw in the background? If so, any complaints ??

Hi KDC. No complaint at all . I love my 14” Ultimate bandsaw from Grizzly. I use it EVERY day. If I had to clear out my shop, it would be the last to go. The fence it right on and I cut some BIG wood on there with a 1/4 ” – 10 pitch blade. I used to change blades but now that is my standard for almost everything.

Phew…That’s good to hear. Just recently I purchased that model by Grizzly. It is on it’s way to my home. I took a gamble and ordered it online. First time making a large purchase without seeing it in person first. It would have been a 7 or 8 hour drive one way to the nearest Grizzly facility in Springfield MO. Between the gas, hotel stay, and time away from work it obviously would have cost considerbly more than the $75 for shipping. Making that online order has been in the forefront of my mind. So I think thats why I was able to see your bandsaw in the background of your pictures. It just stood out. I’ve seen your projects and you do great work. It’s clear you have experience and knowledge. I thank you for your response

KDC…you will be delighted. I ordered mine through Amazon on line and I bought a Grizzly jointer on line as well. I had a little problem with the jointer( the key dropped out of the drive pulley after 4 years of use) but that was becasue some Chinese guy did not hit the torque spec , I reckon. It is a great running machine as well.
Take a look at my blog on dust collection on that band saw. It works pretty good. Some dust still comes out the top but you will never trap it all. I made a 6” riser for mine, but you can buy the kit for about $80. I’m a cheapskate so I made it. It lets me cut 12” high stuff with a 105” blade…...........Jim

Seen your creative dust collection solution. Will keep that in mind when mine shows up and I get to put it together. I also ordered a 1/4” 10 TPI raker blade. I read too many reviews saying the 3/8” blade that comes with the saw isn’t any good. Thanks for the info

kdc68… I agree, you will happier than little red riding hood after killing the wolf! LOL

I have had my G0555 for some time now… I feel like Jim… It’s my favorite power tool…
I tend to stick more to a 3/8” blade though… I have used the 1/4” blades & I like them too!
You will LOVE it!

There is ONE rule that I adhere to for safety:

Never have your hand(s) directly in-line with the blade as you’re cutting… no matter how far away you are from the blade.

You never can tell when the wood you’re cutting may have a hard spot in it… that slows things down and causes you to push just a little harder to get it through it… then, when through the Hard spot, speeds up… If you are too close & in-line, you could very easily get cut!

So, that’s MY #1 rule with the Band Saw…

Be careful!
