DIY Pocket Hole Machine Build Video ep3

- During the Winter of 2000, I worked at a cabinet shop while in college. My introduction to pocket hole joinery was using a Porter Cable Pocket Cutter. Since then, I have been spoiled and have hated using Kreg jigs due to the tear out on the hole and the angled pilot hole that makes it hard to keep the surface flush . So I decided to build my own pocket hole cutter based on what I remember of the Porter Cable version I used 15+ years ago.

Id love to see some plans. This is awesome!
Thanks for the detailed build description and demonstration of your pocket hole machine. You mentioned that there was a bit of math involved in getting the correct router bit rotation. You also mentioned your objective of getting 15 degree screw trajectory like the Kreg jig.
Given the length of your machined bores versus the Kreg example shown at 0:42/8:01 of your video I would guess your machined angle is considerably less than 15 degrees. Probably between 5-10 degrees.
In the hope it might help others interested in replicating you excellent build, I believe the pertinent trigonometry formula to use is: Length of bore= terminal bore depth/tan(design trajectory angle). Assuming a terminal bore depth of 3/8" (half the depth of a 3/4" piece of milled stock and a bore angle of 15 degrees the length of the bore from first contact to final depth would be approximately 1 1/8 inches (3/8"/tan(15). At 10 degrees the bore length is 1 3/4" (3/8"/tan(10) . At 5 degrees it would be 3 5/8" and at 4 degrees it would be 4 1/2".
Interestingly, as I reviewed other manufacturers specifications I noted the bore angles for routed slotting machines (Castle, Maksiwa) in the 3-5 degree range. My conclusion is that the lower the trajectory, the lower the risk of misalignment when making the screw connection. Also lower entry trajectories would appear to result in a generally stronger connection with reduced risk of unwanted breakout. I am guessing that 15 degrees rather than being some magic trajectory was simply the lowest a drill bit based boring jig could go while still being able to initiate the bore.
I just got interested in pocket hole machines. The Castle looks amazing, but expensive. Found a Wood Smith video on a diy version that looked interesting. But, theirs you have to use a hand drill in a second operation. Now yours is genius! The right angle drill is a great idea. I'm gonna try and make one like yours and throw the stupid blue jig away once and for all. Thanks for the video!
Did you make one? Any incite on plans or the math for the pivots?
@@richardcranium978 Have not built one yet. Sadly, I've gotten sidetracked with other things. It's still in my plans to do so.
I remember that machine, and almost got around to buying one, and then it was abruptly gone.
Nice, Do have the plans for this yet?
I'd love to see plans, I'd couldn't grasp how both machines were run with the same handle. I agree, the Kreg holes are so rough
And the angled hole does cause problems with alignment. Thanks for posting, Great Project.
Thanks for watching. I am working on plans now. I will let you know when im finished.
I would be also interested in purchasing plans. I understand your comments on little interest, it is a unique and specific purpose machine, and I certainly understand the time it would take to make them. If it ever happens, I’m in. In the mean time I’m thinking of getting the PC jig. Thanks, KJ
I’d love to see plans on this.
This is really innovative. I've never seen anyone do this before. Well done!
Thanks!!!
awesome design, Wes. I was thinking of making a simple pocket hole jig but this is really well thought out man! I'd like more details on the mechanics of the dual cutting action👍👍👍
Nice build, and video.
Thanks
Totally interested in a set of plans. If you get them made up am more than happy to purchase them from you. Your time to do that has value so don't short yourself.
I've been using this machine for about 6 months now and absolutely love it! Let me kn ow if there is any interest in plans. if there is enough I will knock a set out!
Let's get those plans going!
plans please! nice work!
I will start on them this week!!
Can you use a rotary tool with a router bit?
or a drill with a router bit?
Ok I'm going to need to see the drill side better!! I've got plenty of routers laying around.. Castle uses trim routers for the drill bit part
Very nice invention!! Do you have any plans for purchase?
No plans - I get it. Can you put together a short video of the drill component please? Thanks...
Great machine and such a clean cut... I'd love to see plans
I'll let you know when I finish them
Thank You
I gather from the correspondence that you haven't prepared plans. Unfortunate. Our loss. Would you by chance be able to describe the location of the pivot point?
So any chance if we get to a $# that would make it worth your time to draw up plans at least of the router mounts and pivot point? The inside I think is where the magic is.
What size router bit do you use?
I doubt we’re ever going to see plans on this folks…
How's your machine working out for you these days?
Almost 2 years now. Guess the plans fell through.
Ted Byus didn’t seem to be enough interest to make it worth the time to make them.
sorry to hear there was not enough interest. I'm going to give it a try anyway. Thank you for your video.
Ted Byus yeah, I got less than ten request for them on here and after starting in them realized how much work it would be. If you have any issues or questions feel free to ask
You mentioned working with a PC machine at one time and kind of used what you remembered about it as a reference. I down loaded a PC model 552 manual and schematic to study. I have an old model 550 but it is not at all like the 552.
