  • Groz #5 (Jack) Plane Review

    Recently posted about the clearance on Groz planes at Woodcraft (in the Bargain Alert forum). That posting received a lot of comments, so I decided to share my results once my jack plane arrived.

    The short story is that the workmanship from the factory was not great. But after a 1/2 hour of tuning it up the plane cuts great and I would not hesitate to do it again. I feel like it was a great value.

    Groz #5 (Jack) Plane Review


    Purchased the Groz #5 Jack plane from Woodcraft (web) and had it shipped to me in Jan. 2012. At that time, Woodcraft had the Groz planes on clearance and the #5 was $17.99 (plus $7.50 for shipping).


    Out of the box:

    I had hoped to use the plane right out of the box… so I could do a before and after. However, when the plane arrived it was in a cardboard box with no instructions or paperwork of any kind. In addition, the manufacture had coated the metal to prevent rusting. I have no idea what the coating was but it had to be removed before the plane could be used. Because of this I needed to disassemble the plane without using it.


    Preparing the plane
    I used mineral spirits to remove the coating. It was everywhere (including under the frog).

    Once the coating was removed I decided to flatten the sole. I “painted” the sole with a permanent marker and sanded the sole with 100grit sand paper (attached to a granite tile). It took about 60 seconds of sanding to flatten the sole enough that the marker was completely removed. I repeated this same process with 220 grit and 400 grit paper. The result was a very flat and smooth sole (total time about 10 min).


    Next I used a small file to remove all burrs from the mouth of the plane. In the corners, under the frog there was some paint that needed to be removed. After “cleaning” the mouth, I also filed lightly on the frog to ensure flatness and secure seating of the frog to plane. (maybe 5 min.)

    One thing I did not like about the Groz plane was that the screw. positioning the frog relative to the mouth, could not be adjusted with the frog in place. The knob used to adjust blade height was in the way. This forced the user to adjust the frog screw and then install the frog to see if it was ok. If not… pull off the frog adjust the screw and try again. I positioned the frog so that the angle of the mouth and the frog align perfectly.

    Also of note was that the blade did not sit centered in the middle of the mouth. When assembled the blade was ~1/16" from the right wall and maybe ~3/16 from the left. I don't think it matters, but does highlight the lack of precision in the manufacturing process.

    Sharpening the blade
    Woodcraft has a blade sharpening service, but the pictures I saw in some reviews did not impress me. So, my blade arrived without any additional sharpening. It was sort of sharp, but since it was already off, I decided to sharpen it myself.

    I have several granite tiles with different grits of sandpaper glued to them. Using the “scary-sharp” method, I started at 220grit and went up to 600 grit. (Flattening the back and sharpening the bevel) By the end the blade had a mirror surface that was sharp enough to shave with. (total time 15 min)

    Actual results
    After assembling the plane. My first use was on some oak that I had “resawed” down to ¼” thick using my band saw. The surface of the oak after the band saw was very jagged. With my new Groz plane I was able to quickly clean up the surface so that sanding was optional.


    The shavings from the plane were paper thin and the chip breaker did a good job of removing material so the plane never clogged.


    Conclusions
    I am very pleased with my new plane. While the plane arrived in no condition to be used and the craftsmanship was not top notch, the results make we feel like the $25 and half-hour or “tuning” were completely worth it. I would not hesitate to buy another Groz plane.

      Thanks for the review. Your results with the #5 were slightly better than mine. I had to flatten the frog somewhat on mine, all of 15 seconds with a needle file to remove a burr that didn't belong... Other than that, I tend to agree with your review...

      I wanted to post a quickie update to my response here. I know Woodcraft has stopped selling these, not sure who, if anyone has picked them up, but what I do know is that I have the Groz #4, #5, #6, and #7 bench planes, and the regular block plane.

      The tuning / flattening time needed varied depending on the specific plane, the #5 was the furthest out, the #7 aside from needing to be sharpened, was dead on...

      It's been a couple of years of hard service for the #4, and #5, the #6 and #7 have seen heavy service in the 8 months I have had them, and the block plane just looks pretty in my cabinet as I rarely ever use a block plane...

      Once the planes were tuned, and run through their paces, I have had plenty of usage of them to decide what I like, and don't like. Fit and finish on these, while certainly no Veritas, they are quite nicely made. Some fine tuning to the frogs on each of the bench planes was needed, as was flattening the iron and chip breaker on them. The hardwood tote and knob on each fit well in the hand, and offer easy control of the plane... Adjusters are good and solid, although lateral adjustment is a bit tricky to get spot on right at first.

      The biggest complaint I have should be no surprise to anyone, and that is the blades / irons on these wear fast, and nick easily. Right now I need to rework my #4 as I managed to nick it on a knot in a piece of pecan I was working. Not the end of the world, but a bit annoying.

      I am completely free and clear of any buyers remorse over these planes, but I will, in the long run, be upgrading these to Lee Valley blades. I really want something harder than what they ship with...

  • A review of the Kreg Precision Trak & Stop Kit
    by twistsol

    Summary
    I built my miter station last summer and used the Kreg Precision Trak & Stop Kit. The kit was just the starting point. 8 feet of track and a single flip stop didn’t meet my needs since I was building a miter station the width of my shop, nearly 24 feet. I added four 48” pieces of top track and three additional swing stops so I could have two left and two right. Finally, I added metric rules to the top. Total cost breakdown is as follows

  • Review of VIX-type Self Centering drill bits
    by LCHIEN
    I have always had trouble mounting small hardware on small wood boxes, with the hasps and hinges always looking slightly off perfectly square - particularly a problem with flat head screws and countersunk hardware which aligns the hardware to the hole location and centers on the hole.

    I'm talking small wood screws. I place and mark the hardware carefully and mark the center of the hole with a sharp awl.
    The problem comes about with small bits like 1/16 and 5/64 and 3/32"...

  • Grizzly Overarm Blade Guard review.
    by twistsol
    Since my new shop is in the basement, dust collection is a bit more important than when I had my own building and could do as I pleased in the shop. With that in mind, I upgraded the dust collection on my table saw. I purchased the Grizzly Overarm Blade Guard to use with the saw.

    First impressions were that this is an extremely solid and well built unit. It's made mostly of steel and connects to a 4" DC hose. There were a number of issues getting it set up and installed, and a...

  • Kreg KMA 3220 5mm Shelf Pin Jig
    by twistsol



    I decided to look for the rock bottom cheapest 32mm drilling system available that would let let me create real 5mm holes spaced 32mm apart, that was easy to use, and didn’t require a bunch of setup time. I’m really surprised at how much I like this little Keg jig especially when you consider the price of $34.99, and it has everything included. There were a couple of jigs cheaper but you needed to buy a self-centering 5mm bit to go along with them so they would...

    Here's a tool I found useful for marking. Accutrax pencil blade marking knife.



    I have one I've been using on and off for a while. Its a fine pencil lead in the shape of a utility blade that can be installed in any utility knife handle and used with a straight edge, combination square, saddle square etc. to mark easily seen, fine lines on wood..

    Here's mine. I have not broken it, it seems to be quite sturdy. The sharp edge lasts a long time. I'm still on the...

  • Saddle squares
    by LCHIEN
    Hey, I'm sharing one of my favorite tools. A Veritas Saddle Square. Actually I have two in different sizes. This is the large size for marking 2x4 and 4x4 (shown on 4x4 here). One of those tools that makes woodworking a pleasure.



    They're great for continuing lines from side to side. And even side to opposite side.
    Works really well when the board has a rounded edge or some wane where the edge is not really sharp and square but the two adjacent faces are square to...
