Telescoping Lathe Dust Collection Arm

There’s one advantage to a fixed head lathe; the source of dust and chips is always in the same spot!  Given a dust hood that can cover 10″ you’re set for most projects.  Given a sliding headstock lathe and now your dust collection needs to be a lot more flexible, it will have to travel a few feet in either direction.

When I first got my new lathe I made a dust arm that mounted to the lathe body but I didn’t like it because it was always in the way of the banjo.  The next version is a telescoping arm that mounts to the wall via a French Cleat.  So far it’s worked really well, here are some photos.

It’s a pretty simple design.  The arm is sandwiched between two boards, pinned with a 1/4″ carriage bolt and plastic knob.  Notice how the cleat is quite long, this was done to accommodate the side-to-side wobbliness of the collector as it’s moved.  An earlier version had a narrow cleat (~5″) and it would tend to tip out.  The extra boards on either end also help it stay put.  The surround is four pieces of wood glued up to form a rectangular tube.  A piece of 1/4″ plywood glued on top provides a mounting point for the plastic hood.

The arm is about 10″ long while the surround is about 9″ long.  I found that the surround only needs to have about 1/3 of the arm inserted into it in order to provide a stable connection so I cut the arm back such that at maximum extension the surround has this much engagement.

Careful sizing of the parts help it slide smoothly as does a good coating of paste wax on the arm.

The plastic dust hood is  the magnetic jobber sold by many vendors.

Repeatable Taper Rip Cuts with a Sliding Table Saw

Over the year that I’ve owned my sliding table saw I’ve really come to appreciate the convenience and safety of having a built-in crosscutting & ripping sled.

I just finished a set of tapered legs which on a normal cabinet saw one would use a taper jig to cut.  In this post I’ll show how I accomplished the same thing with my sliding table and two hold-down clamps.

Finished product first.  Four legs that started as 2″ squares.  The taper starts below the mortises (about 4.25″ from the top) and ends a half-inch from the bottom edge leaving a 1″ square foot on the bottom.

Finished legs

These photos show the uncut leg with the taper penciled in.

This photo shows how the legs will be positioned on the sliding table.  The cut starts at the foot and will end a little short of the mortise.  The leg is pushed by the miter fence while its taper angle is set by the fence’s flip-stop.  An important note here: I am indexing the cuts from the waste side not the good side.  This always gives me a square surface to set up on.  If I indexed off of the good side I’d have to deal with trying to index off of a taper which would involve making shim blocks.  Nuts to that.

Setting up on the slider required establishing two indexing points.

  • One for the foot set 1/2″ inch from the blade.  This is the easy one I just used the fence.
  • A second one to establish where the cut will stop near the mortises, 4.25″ inches from the top.

The second indexing point was harder to set up because that point is out in space.  I needed to move the flip-stop to “aim” the cut at the desired point below the mortises.  I gave myself a target to aim at by clamping a stick to the table at that location and then cutting it off:

Now with the stick in place I could move the flip-stop around to get the stick flush with the place I wanted the taper cut to end.

After confirming that the setup worked fine on my test piece I cut all the tapers.  Two Kreg hold down clamps did a fine job of keeping the work in place and my hands away from the blade.  A Diablo ripping blade left a very nice surface which only left behind very faint tool marks; a few scrapes and the surface was ready for 220.

Dubuque Bar Clamps vs. Harbor Freight Bar Clamps

I needed two more 48″ clamps on my current project and because it’s just a simple carcass I thought I’d give Harbor Freight’s a try.  I already have some Dubuque clamps so I’m able to compare the two.

ClampSidewallComparison
Sidewall Thickness Comparison

As you can guess, the Harbor Freight clamps are a lot shittier, just look at the sidewall thicknesses above.  On the HF clamps the whole assembly twists while you’re putting them in place and none of the other components are as well-made.

However for the purposes of this particular project they work just fine.  Once you have them lined up and tightened they can hold a cabinet together just as well as much nicer clamp.  And their light weight makes them really easy to maneuver into place unlike my heavy 48″ Jorgensen Cabinet Masters.

So while I don’t think I’ll buy any more of these they can service lightweight assembly jobs just fine.

Tormek SVD-186 Gouge Jig Review and Comparison to the 185

I just got Tormek’s SVD-186, the newest version of their gouge jig.  Having both the SVD-185 and 186 on hand I was able to compare them and weigh in on if it’s worth the $100 upgrade.

Some highlights:

  • The wider body would nice if you have really wide gouges but unless you’re doing hand-carving with bowl gouges this probably isn’t an issue
  • The fixed clamping bar is appreciated, no more having to hold the spinny brass one in place with your thumb.
  • Shame on Tormek for not using detents on the 185!  They make switching jig settings as easy as you would expect
  • The casting metal is different, it has a textured surface and is heavier.  The new jig weighs 12oz as opposed to the 185’s 7oz weight.

Here’s a video review where you can the two jigs.

But in the end if you already own a 185 I don’t think it’s worth the cost to upgrade.  The 186 is certainly easier to use but $100 could likely be put towards more useful shop upgrades.

4-in-1 CBN Wheel Review

I recently upgraded the wheels on my Rikon slow-speed grinder to a pair of Woodturnerswonders 4-in-1 CBN wheels.  Half of the reason for the purchase was curiosity and the other half was frustration at my Tormek’s constantly glazed-over wheels.

I got a pair of 80/220 wheels and am really happy with them.  They grind cool, leave a great edge, and best of all don’t need any maintenance.

Here’s a short video review on the wheels where I talk more in-depth about those positives as well as how I got them trued up to within 1/1000″ side-to-side runout.

Midi Lathe Stand inspired by Alan Lacer Design

A few months ago I made a new stand for my Jet 1221VS based on Alan Lacer’s article in Popular Woodworking.  I liked the design because it had a small footprint, space for sand weight, and solid construction principles like doubled-up plywood and canted legs.  It’s worked out really well for me.  It’s very solid delivering a stable work platform without a lot of bulk.

Some quick facts about it:

  • 29 ½” high
  • The top is 13″ x 38″ and is made from three layers of ¾” MDF

Here she is:

As you can see I didn’t deviate much from the design in the article, but some key points are:

  • I used cross-dowel nuts (13-CD040 from Woodpeckers) instead of copper pipe.  They worked very well.
  • MDF for the top because I had some left over from my old bench
  • Dimensional pine lumber for the cross-members
  • The tool shelf was secured with bolts / cross-dowel nuts instead of wood screws into end grain
  • I added a tailstock caddy
  • The tool shelf is made from pine lumber (two pieces jointed together)

My bench is shorter than the one in the article in order to accommodate the spindle height of my lathe and my elbow height.  This unfortunately squished the shelves closer together which compromised the opening above the tool shelf and also limited me to two sand bags.  I didn’t want the sand shelf to be too close to the floor such that it would hinder cleanup.

So if you are on the hunt for lathe bench designs this is a good one to consider.  I will say that it does require some degree of skill and accuracy to build.  Your 5° angles all need to match one another.  The bolt and cross-dowel holes are tricky to get aligned just right; The cross-member with ugliest dowel holes went to the back on my stand!  If you are using lumber in the build you will need it to be S4S.

JDP-17 Review

I recently upgraded my drill press to Jet’s JPD-17 model and am pretty happy with it so far.  I wanted something with at least 5″ of quill travel and a laser guide and this one fit those specs and my budget.  The woodworking-oriented table is a plus, too.

My drill press works exactly as it ought to.  It was simple to assemble and everything fits together as intended.  The foot is adequately sized and it feels safe free-standing although I do plan on bolting it to the floor at some point.  Operation is smooth and quiet.  The depth stop works well not feeling at all “mushy”.  There is a distinct clunk when you hit bottom.  My only (minor) complaint is that there is a bit of paint overspray on the top surface of the table.

Out of the box the table is pretty darn close to square with the quill in both axes.  One of the lasers was just a tiny bit off, I don’t think that I really needed to adjust it but I did it for fun.

Dave’s Workshop on YouTube did a great overview video of the tool:

About the only interesting fact I can add to the discussion  are some details around the T-slots on the table.  The manual states that they are 1/2″ wide by 5/8″ deep.  This is pretty close to accurate, here are the measured dimensions.

JPD-17-T-Slot
T-slot dimensions

 

For your fences and other jigs, note that a 5/16″ hex-head bolt fits nicely and won’t turn while a 1/4″ bolt will turn within the slot.  I don’t have any t-slot bolts to try out.

Bowl Turning Tips

While roughing out a bowl I recorded two short videos.  In the first I try to provide some detail into how to do bowl hollowing cuts, and specifically the entry thereof.  When I started this hobby I had a really hard time figuring out the best way to do it despite watching lots of videos and reading books.

In this video I show a marking jig for a set of chuck jaws.  It lets me draw a circle for either the recess or a tenon.

Grizzly G0700 First Look

Update: In the late summer of 2015 Grizzly discontinued the G0700.  However this information is still valid when applied to their other 10″ sliders.

If you google “Grizzly G0700 review” you’ll get a few press releases and the saw’s page on grizzly.com.  Well I took a gamble on it and got one anyway.  I’m happy that I did, it’s well-made and fits into my small basement shop.  The sliding concept appealed to me because the sliding table would seem to replace many of the sleds I see others using on traditional cabinet saws.  We’ll see!  In the meantime it’s worked just fine for me.  I’m upgrading from an old Craftsman contractor saw so a 5HP machine with a fresh blade cuts like a dream.

In the meantime I did a short video showing the details that you can’t see on Grizzly’s website.

I A few things were different from the product page from my saw which was manufactured in January of 2015:

  • Clear blade guard
  • A scoring blade was included, whereas the product description says it doesn’t.
  • Miter gauge is a thick, cast piece of metal instead of a thin stamped piece.  It’s the same setup as seen on the G0623X.
  • The miter fence does not have the end support for long pieces

Here are a few photos I took when I received the saw.  In order to get it down into my basement I had to remove the cast iron  which also afforded me a view of its guts.

Stir Crazy Turbo Oven Roasting Process

I’ve had success with a very simple, cave-man like approach to roasting coffee with my SCTO setup.  Success to me means that roasts are very predictable and that I enjoy the coffee.  As an aid to other roasters that might be having trouble wit this setup I recorded a roast session.

In it I talk about pre-heating, temperature control (or lack thereof), and the cooling process.
