Making a Bow, part Two

December 31st, 2010 by Orkraider

I’ve now had a couple days where I’ve been able to spend some time working on bows, so here’s part 2 of Making a bow. Brad was kind enough to bring in a much better camera, so here’s a pic of the front profile of the bow as it stood at the end of part 1:

Wednesday Night Roundup – Montage

A Japanese Style Lamp

December 22nd, 2010 by jrsphoto

Many of you have been curious about the Japanese lamp I have been making over the past few week so I figured I would post a few pictures of the finished project.  I went in to the hack factory today and finished the final piece, the brace that would hold the candle, which in my case is a very realistic looking – battery operated candle.

There are three basic parts to the lamp.  The inner frames, the outer legs, and the top.  The frames are made from 1/2 inch maple, with simple lap joints to interconnect all the frames. There are a total of 4 inner frames and each frame is connected to the other frame at 90 degrees with another lap joint.


Once I had the inner frames done and covered with paper on the inside, it was time to make the outer legs. I made 4, roughly 1″ square outer legs that support the inner frames again using lap joints.  There are small dados in each of the legs that the inner frame mates to.

Not exactly sure what wood I used on the outer legs or the top piece but its basically just a square frame of 1″ x 9″ hard wood with 45 degree miters on each end.  Once glued up, I did a simple round-over using our router.  I spent several days sanding and rubbing on 3 coats of tung oil.

If anyone is interested in making one, let me know and I’ll loan you the book.

Making a Bow, part one

December 20th, 2010 by Orkraider

I’ve been threatening to blog what I’m doing at the space for a bit now, so here goes.

Today I decided to start making a pair of bows, as christmas presents for my brothers.

These are going to be made out of red oak, using some 1″x2″x6′ boards I got at menards.  They’re going to be self bows, which means each is made out of a single piece of wood, with no gluing.  I’m shooting for about 50 to 55 pounds draw weight at a 28″ in draw, which should be doable with this wood.

For starters, I picked through all the boards, looking for one that was straight, with no bowing or cupping:

Saturday at the HF

December 18th, 2010 by Booka

I stopped down to play with some passive solar concept I had for removing Ice Dams on my roof, and I found Pete working on his CNC rig (he professed to be there to work on drawers, but he must have gotten inspired on the rig.)


Wednesday Night Roundup

December 17th, 2010 by otto_pjm

In an effort to capture an overview of the projects going on at the Hack Factory and introduce some of the TC Makers who have had less online exposure due to being more stuff than bits people here is the first of a likely irregular series of the Wednesday Night Roundup.

In no particular order here are some of the people and projects happening on Wednesday December 15th. ( I took lots of pictures, most were bad, and a fair portion completely unusable hopefully things will go better next time, similarly I’m easily distracted and the HF is known for having not only lots of shinny objects, but also squirrels, so my understanding of the details, or even the general idea of the projects maybe incorrect )

In the Classroom / Lounge area:

Steve was starting on
an Arduino project
using input from a pneumatic ,
or perhaps hydraulic sensor.
Jim was also
working on an
Arduino project,
he had mouse positional
information controlling
a servo with some high
tech coat hanger
apparatuses attached
to it.

The goal as I understand it
is to use visual feedback
to allow the servo to balance
the contraption.

Woodworking at the HackFactory

December 16th, 2010 by jrsphoto

It might seem at first glance that the HackFactory has turned into a woodworking shop. It seems that all the new wood has spawned an awaking of woodworkers in all of us. It has been great to see so many people working on such a variety of projects. Even those of you not familiar with woodworking have been making stuff.

With all these new found woodworkers comes dust. Lots of it, and its everywhere. Especially from stuff like MDF. And it’s not just in our area. Take a look at the metal working area after a few hours in the shop and you will see the sawdust on the table.

If all of us that are using the woodworking space do a little extra it will make a big difference for everyone. The time it will take largely depends on the time you spent there and the materials you were using. If you were there for 5 minutes and working with the drill press, it should only take you a few minutes. If you were there for an hour working with MDF, it will take you considerably longer.

We all have to try extra hard to keep the shop clean. Keeping the classroom and office space doors closed will help keep dust from these clean spaces. Make sure you take the time necessary to clean up your area and any tools you may have used. Vacuum the floor around any space you have used.

Keep in mind that some of those woods, MDF included, release vapors that are really bad for you. If you have a mask, you should be using it.

One last note, if your working on a project and need to leave the hack factory, take some time and clean up your space. That way if for some reason you don’t make it back, others can use the tools and table space and not have to clean up your mess.

If everyone spent a little extra time and clean up a little better than it was when you got there, it would really help.

Experimenting with CNC Dovetails

December 5th, 2010 by otto_pjm

I’ve had a wizard to do Dovetail joints for awhile and never had a reason to use it until now. We need some drawers built for an odd sized cupboard, and as you may know the HF recently received a pallet or two of drawer sides as a donation. So it seemed like a good time to check out the wizard and try and make some drawers.

Here’s a shot of the setup,



It’s kind of a pain as you need to operate on the edge of the board. I built my latest table in two pieces so I could do dovetails and put the 4th access I hope to build under that part of the frame.

CNC Router Operator – Check-out class 12/12 9-Noon

December 4th, 2010 by otto_pjm

Due to the weather the class will be rescheduled sometime in January. The User Guide is ready for review, I’m trying to figure out how to get it posted at the moment.

This class is primarily targeted at TC Maker member, who wish to use the CNC Router. The intent is to give practical step by step use and operation instruction. The public is welcome to attend, but due to the focus on one specific system and the time limitations general questions about CNC systems and tools will only be addressed as time allows.

CNC Router user operation training class, allows you to use the router to work on your own projects

The HackFactory

Sunday December 12th from 9:00 AM to Noon.

What you’ll need:
Nothing really, you may want to take notes, (I hope to have a rational step by step guide put together, but holes will certainly exist) also laptop’s (or classroom PCs) with design tools to create 2D or 3D object maybe useful. (formats such as EPS, dxf, stl, etc)

Non-members and those interested in CNC, but not wishing to run a CNC Router

I intend to have additional Cut, Turn and Burn classes in 2011, and these are the forum for general questions and will deal with the end to end process turning ideas into physical objects.
