Bandsaw: Update 14

The bandsaw is nearing completion. The little things about the build are slowing things down a bit, such as finding hardware and cosmetic details.


This is a pretty good angle of the nearly complete bandsaw. The motor pulley cover has had its binding installed and was attached to the lower enclosure. You'll notice in most recent shots of the saw that the top drawer is never closed completely. That's because I made it with too little clearance and the drawer won't close at all since the stand frame has shifted over the past few months. It's an easy fix.

The under-table cover is finished. I have some screw inserts that will allow this piece to be tightened to the frame. I will install these soon.

I still need to find suitable draw latches for the enclosure, which is turning out to be quite difficult. Most latches are either too big, or too off center. I'll figure something out eventually. I'll need to get a few knobs for the various 'tightenable' pieces such as the table trunions, blade guide column, blade guide, and blade tracking. I'll have to order something from the interwebs soon. Other than that, I'm able now to dismantle everything, sand, route (round-over the frame), and finish. Afterwards I'll button everything up and tune a few things such as table leveling and upper wheel shaft wobble that I've noticed. More later.
 

My mother asked if I could make a table from a wooden wagon wheel she had. I designed something quickly in AutoCAD and started cutting some wood.

I got a good deal of 'smoke damaged' ash boards a few weeks ago. The boards are 3/4" thick and don't have any 'flutes' underneath. There are only the tongue and groove to deal with. I cut some to length here for the main support.

I cut them to width by mitering the edges to 22.5 degrees.

The pieces laid out, with a dado for the top support. In hindsight, I should have added another center octagon to improve the structure. No problems now, but I imagine the miters won't hold perfectly on their own over the years.

I then formed an octagonal pillar. This was quite interesting to glue together. I'm using Titebond III leftover from the ES335 build. Since this table will be outdoors, waterproof glue would be preferred.

Here's a view of the printout CAD model, and the 45 degree table legs. They will be 3 layers of 3/4" thick (1-1/4"), so I have 12 pieces cut out here.

I trimmed the tongue and groove, and planed the surfaces to promote proper adhesion. They are then glued together.

I used my bandsaw to cut a pleasant little curve into the supports. I then cleaned it up with the spindle sander. 

A quick mock up. Looks alright.

I routed the edges with a round over bit to give it some looks. I then used the drill press, with the table at 45 degrees, to drill holes for the 3/8" hanger bolts. I filled the holes with wood glue and threaded the bolts into the wood. Two nuts were threaded onto the machine end so it can be torqued using a wrench.

I assured the pillar support thing was square to the table, and transferred the bolt locations to it.

I drilled the holes, added a washer and nut, and tightened the legs. Violin. 

Very little wobble. I will sand and finish soon. 

Check out the 'Browse' menu at the top right of the page to navigate my blog a little easier. I hesitated to spend time organizing this blog, since I'd rather spend time building an actual website, but this will do.

More later,
Andrew
