  • Oshlun 10" 60T ATB Crosscut Blade

    A few weeks back I needed a replacement blade for my CMS and got lots of great recommendations from the folks here at BT3. I wanted something that was a good value and originally was considering the Porter Cable Razor. Brian at Holbren informed me (us) that he is now carrying Oshlun blades (I think Oshlun is the old Avenger crew back on the road) and that there is a 60T blade that might fit my needs at a reasonable price.

    I decided to try this blade, I also tried the PC as I had an immediate need and could get it at HD and take it back later if I didn’t like it.

    Although I was originally looking for a good value blade for my CMS I tried this blade in both my CMS and BT3100. Firstly by comparison to the standard 40T blade, the Oshlun (and PC) were great improvements as crosscutting blades. My 40T blade does need a good clean but I think it is sharp.

    I experimented with various grades of ply, some laminated chipboard, Poplar and Red oak.

    I didn’t do any major ripping as its not what this blade is for, however, anything cut with the grain cuts very clean on all sides. The overall cross cut is silky smooth. The top edge is very clean. The bottom edge does have some slight tearout as did the trailing edge on the TS (possibly a little more). I did have a ZCTP installed but if used in the TS a backing board would help. When I put it in my CMS I had similar results re: smooth cut and top edge. The trailing edge was near totally clean but I guess this is more to do with the cutting angle and motion of the CMS when compared to the TS. The underside had more tearout but I had the standard wide clearance slot installed. I cut a clean ZCTP for this blade on the CMS and the tearout improved dramatically but did not go away completely.

    Overall this was a major improvement crosscutting when compared to the standard BT3100 combo blade. I don’t have any experience with any of the expensive and fancy Freuds or WW blades but this blade really does offer good value for money.

    As I mentioned I did have a use for my CMS the weekend before I received the Oshlun blade so I did buy a Porter Cable Razor to try, it’s a 50T variable tooth blade. Results were comparable but I think the Oshlun had less tearout than the PC. Both the Oshlun and PC are supposed to be 1/8" kerf. The PC measured slightly under and the Oshlun was slightly over. Not sure if a TK blade helps much on crosscuts and I don't think it matters much on the CMS.

    The Oshlun Blade will stay installed on my CMS and the PC blade will go back to HD. If I get into using some expensive HW ply I might need to consider a higher tooth count to get the best cut on the lower side when in the TS.

    I will admit this was NOT a huge science project but overall I think the 60T Oshlun is great value and other than some minor tearout produces a great quality cut.

    • 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...

    • Knife marking pencil Accutrax
      by LCHIEN
      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...
