  • PennSt:Variable Speed Midi Lathe Conversion Kit: for Turncrafter , Jet & Delta Lathes

    I bought this unit to turn my Turncrafter lathe into a variable speed lathe.

    In the kit, you get the new brush motor, speed controller, and associated hardware to make the conversion.

    I bought this unit in Dec 2011. It worked like a dream for 6 mos. Had good linear speed control. Then, during a project I was turning for my sister's birthday this weekend, the unit died.

    The controller has failed. This was just with occasional use. The motor brushes are fine, the fuse is fine, reset switch is fine etc. I design custom controls for a living, so I knew my way around this controller. The warranty was 30 days. I'm out $100.

    I hate to disparage any tool or company because no company nor product is perfect, but I'd feel bad if anyone here bought this kit and experienced the same thing I did.

    I put the original single speed induction motor back in the lathe to finish the project. I don't care for moving the belt from pulled to pulley, so I believe I'll pick up a name brand variable speed lathe down the road.

    This isn't the first time I've had an issue with a PennState product. I believe I may shop elsewhere from now on.

      I don't believe there's anything special about that speed controller. Looks like the kit comes with an ordinary universal motor (one with brushes) that runs on 0-110V AC or DC. I think this is it?

      I would think it the speed controller broke, you could very successfully replace it with any of those off-the-shelf router speed controls.


      either of these (15- and 20-amp models) would work considering Penn State says the motor is a 1/2 HP motor (about 3.5 Amps max):
      http://www.mlcswoodworking.com/shops...d_control.html

      Just add an AC plug to the leads from the motor and plug into the controller.


      P.S. one of the reviewers on the Penn state web site said that he has several of those and dust in the power switch is a recurring problem, apparently the switch is not sealed. Try blowing out the switch with compressed air or if you know your way around electronics, bypass the switch. Or use an ohm-meter to check the switch.

      your profile says you do custom controls but I'm not really sure exactly what that means. could be electronic controls but it might not have anything to do with electronics.

      Loren,
      I design custom electrical control panels and have a degree in engineering electronics. The unit had no dust, I'd kept up on that and kept it protected. The switch was fine, I tested it.

      Yes, I can replace the controller, but my point for others was to beware of this unit in that it's weak.

      On the pen forum, quite a few people, including me, have had problems with this unit. The problem for every single one, including me was the switch. It seemed like the controller itself. This is the first one that I noticed of the controller itself dying.

      What was really weak to me was the motor itself. Itb does fine for pens but when I put a 12 inch bowl blank on mine, it did not have the power to work it except for tender touch-n-go type of cutting.

  • 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...
