Speeding Up G7947 Depth Adjustment

By Jack Barnhill On July 31st, 2011

When I rebuilt my used Grizzly G7947 drill press, I retrofitted it with a depth-stop.  The G7947 was so old that that it was manufactured without one.  I guess it was only supposed to be used for drilling through-holes.  Here’s a shot of the standard G7947 depth-stop.

It worked fine, just slow to adjust.  Grizzly recently started carrying push-button (or quick thread) depth-stops but not in the size to fit the 12mm depth rod for the G7947.  They have models in 8mm, 10mm, 3/8-16 (about $14 including shipping) and 1/2-13 (about $16 including shipping).  Delta also has a push-button depth stop replacement part with 1/2-13 threads for about $11 including shipping.

 

I opted for the less expensive Delta version and picked up a piece of 1/2-13 allthread from the orange box store to use as the depth rod.  The ½” allthread was too large to fit the mounting bracket on the drill so I drilled out the bracket to fit the new stud.

After mounting the new depth rod with the new stop everything works fine except for one thing.  It is easier than I would like to overpower the spring inside the push button and cause it to jump a thread; not real easy but easier than I would like it to be.

Now I’m on the hunt for a stiffer spring.

Has anyone used one of the Grizzly quick-thread depth-stops or have a source for small but moderately stiff springs?

 

 

 

 

 

Edit 8/2/11:  I found a better spring for the stop at ACE Hardware.  The button is only a little harder to push but the stop is much more secure.

Virtual Workshop Layout

By Jack Barnhill On April 13th, 2010

Unless you have tons of experience or unlimited space and funds, setting up a woodworking shop is an evolutionary experience.  Mine started out in a corner of our garage, a garage originally set up for vehicle/trailer housing and general utilitarian handyman activities and storage.  After getting rid of the trailer, I was able to expand my woodworking area but still had to share space with general storage shelves and use the cut-down utility bench for a woodworking bench.  it’s not much good for woodworking even though I did cut it down to a more woodworking friendly height. The top is made from 3/4” particle board with a 1/"4” MDF cover.  The humidity  changes over the years has left it anything but flat or solid.

Anyway, since I don’t have a lot of experience, funds or unlimited space, I thought I would use a couple of computer tools to help me layout my existing shop and help me plan its evolution in an effort to maximize the available space.

The first computer tool or application I used was Microsoft’s Visio.  It’s a quick and easy way to create a floor plan.  The floor plan below is future look at my shop.  It may seem crowded on the one end (that’s the machine or dust generating end) but, everything is on wheels so it can easily be rearranged as needed or pushed out of the way, as shown, if I want more elbow room.

Like I said, Visio is good for quick floor plans.  What it’s not as good at is giving you a 3-dimensional feeling for the shop unless you want to created additional drawings from various angles.  For the 3D model of the shop I went to Google’s SketchUp (SU) app.  Depending on the level of detail you want in your virtual shop and what all you have in your shop, you can create a 3D model in a short time or a while longer.  Once the models of the shop and it’s contents are created it’s easy to rearrange and modify the floor plan.

I’ve uploaded a new image gallery of some scenes created from the SU model of my shop.  While the Visio drawing is of the future layout, this SU model is just the start of modeling my shop as it is today.  I have a few pieces of existing shop furniture in there including my workbench.  If my real workbench looked as good as my virtual one, I might not be planning to replace it with a Roubo-like bench that Chris Schwartz and several others have built.  You can get to the gallery from the menu of by clicking on the image below.

I will update the post and the gallery as I get more of the virtual pieces and details created.  Once the model of my existing shop is completed, it will be fun to start designing and building the new pieces that I hope will add more flexibility and free up some space.

How do you go about planning and setting up your shop?  What do you do to make your shop flexible and create space so you not wasting time and energy walking over, around and through a mass of tools and debris to get to tools or materials that you need at the moment and then over, around or through the maze again to get back to you project?
