Topic tags/keywords: kreg k3 pockethole jig

i didnt find any reviews of this tool in the review section . i know some have bought it and theres been some discussion about it , and i seems everyone is quite pleased with it . once again im the oddball ! ill relate my experience . im not doing it in a review yet as its not completely over yet .
ill start by showing my jig that ive had for several years . it works well and i have no idea who made it . it may well be an early kreg model . it has no name or numbers on it , and the paperwork has long since got sucked into the black hole that i seem to have in the shop .

i bought this jig at woodcraft . as i recall it came with the bit and drill stop all in a nice wood box . at the time kreg had pretty much the same thing in a blister pack and it was plastic jig . so i chose the aluminum one.
one difference ill point out is , if you look at the second pic theres an allen screw , if you loosen it you can adjust the width of the drilling barrels . i use this a lot . kregs does not have this . so i buy this jig along with 2 of the c clamps that kreg sells to hold the pieces flush while you put the screws in .
my reason for buying this is primarily for wainscoting frames that im using buiscuts and clamps to do . this tool will save a lot of time . and it did save some , but i soon learned the clamps left a lot to be desired .

ive used my clamp a good bit and it works great ! so now i have a system that works well and i should be happy right ? wrong ! this jig is designed to empty the chips out a hole in the side of the drilling barrel . some do but must get dragged by the bit up thru the barrel so everytime you drill you have to clear the chips away before setting the wood for your next holes . i find this annoying ! meanwhile kreg has come along with a vacume attatchment for their jig . i finally take the plunge and go buy the k 3 system along with the adapters and smaller hose for my vac . i now have a job that needs 3 large f f . i set up my new outfit and drill enuff stiles to make one of them . wow ! works great not a chip anywhere ! now i decide to put this one frame together to make sure everything is working out right i clamp the first joint put in the screws and the face is not flush ,so i increase the pressure on my clamp and do another joint still not flush . now i clamp it so tight i had to get on it with both hands to lock it down , still not flush . after watching closely the last 1/2 turn of the screw is forcing it out of alignment i cant stop now , the glue is drying so i finished up the frame . and try to fuigure out whats wrong . while im thinking about it i carry this frame across the street to my lumber yard and run it thru their drum sander at 3/4 . some joints werent quite perfect so i go just a hair under 3/4 now there perfect but ive sanded into a few of the screws . im thinking the screws are pulling the stiles out of alignment as they draw up and its obvious the screws are comeing very close to comeing out thru the front of the rail , so it must be a little too much angle on the drill . after reading the book TWICE theres no way to adjust this . so i unhook my new setup and threw it under my bench where i throw my scraps and junk , set up my old jig and finish my job . im a bit lighter in the wallet and back where i started ,dealin with the chips . a couple months pass and im lookin thru my new fww mag and theres an ad for kreg k 3 . this reminds me of the one i have collecting dust . i know from years of experience im not lucky enuff to buy the one in a million winning lotto ticket , however i also know im very much lucky enuff to buy the one in a million pocket jig that wasnt made right . i called the service number off the ad and talk to a tech. named dan . he was quite nice and listened to my rant . the one thing he said that i didnt like was that i shouldnt expect the joints to be perfect . im in no position to debate the issue but i did say that with my old jig and the clamp i made the joints are very near perfect evry time and kreg i think is supposed to be a leader in the pockethole industry i should at least get them as good as i was getting with the old one . with that he conceded and said if something was made wrong its probably the drill block and said hed mail me a new one .
been a week and i havent got it yet ill update this when i get it . im hoping it work out i love the vac . system
it worked great . maybe im being too critical but i bought this system to save time and money . if it dosent do that i dont want it thx if you read this

Hey Verne, I have had some similiar issues with alignment. Every once in a while, driving the screw seems to separate the pieces. Here’s the solution I came up with and it’s worked for me so far.

After I get the pocket hole drilled I switch bits and enlarge the narrow section of the pocket hole just enough so that the screw I’m using slides all the way through without biting into the pocket hole. If you set the collar just a hair deeper than the set up jig calls for the tip of the bit will punch through just enough so you can do this coming in from the back side. With the screw spinning freely inside the pocket hole it actually acts like a clamp and draws the two pieces together.

I’ve also found that if I’m going for super perfect it helps to clamp the pieces together dry, start each screw a thread or two just to mark the location, then take it all apart and drill shallow pilot holes to get the screw started in the second piece. You have to make an educated guess at the angle when you’re doing this but it doesnt’ have to be perfect.

When you do this you have to pay extra close attention to the length of screw that you choose because the tip of the screw usually ends up a little closer to the surface of the piece that you’re screwing to. I typically pick a screw length shorter than what the charts recommends. This keeps the tip far enough away from the surface that I’m not worried about sanding through and so far it hasn’t seemed to affect the strenght of the joint.

It’s some extra effort but it has solved the alignment issue for me every time. I think the issue would go away if Kreg were to make the tips of their bits just a tad bit longer and wider but unitl they do, this is how I deal with it.

Trim,
I have an identical tool, it’s a Carb-a-Tec model (a well known company down under), probably Chinese or Taiwan made. I have used it a lot and find it to be a good tool. There are some minor issues with alignment & the drill guides are not as rigid as they could be but overall I find it effective for some joinery tasks.

hey grumpy that jig does look a lot like my old one . i described it to the tech from kreg and he says it may well be one of thiers so i guess they made an aluminum one before the plastic ones

I have not seen any plastic ones Trim. Not my idea of a long lasting tool.

Take the plunge one and all. Order the Kreg Foreman and you will never look back to your plastic drill fixtures again. What a pleasure this is to operate. I actually believe I can drill a dozen holes in the foreman in the time it takes to clamp, drill and unclamp with the kreg fixture. This thing represents money well spent.

Shaun:
Take a look at this and see if it wouldn’t be a better solution for making the holes.

ed , i was considering a forman several months ago and posted an inquiry on here and the few people that had used them liked them . about the time i was ready to lay down the cash business was starting to go in the toilet so i held off . its still not only in the toilet but i think has now reached the treatment facility ! lol . so laying down 800.00 at this point isnt an option . however the tread isnt about how long it takes to drill its about the angle it drills on and alignment of the finished joints , so my question back to you is what your useing for clamping the joints and are you having any alignment discrepancies ?

No alignment problems. I generally ue the Kreg LFC (Large Face Clamp) for face frame assemblies. Hand pressure or Quick Clamps for face frame to carcass assembly.
