I have been following closely the thread that Bj started on his extremely wonderful idea for a box joint push block. I have been intending on building his exact model, but like many things, it got pushed back until a "better time".

Yesterday was a slow day and I had time to study his model carefully making plans to get started on it today. Yesterday I got out the Oak-Park box joint jig along with some jig hardware I had tucked away for just such a project. I even had the poly plastic handle that OP offers that I had forgot about. I was going to make a first class push block just like Bj was kind enough to share with us. While gathering my supplies, I picked up a tool to move out of the way. This tool is called the Grr-Ripper and I'm sure many of you have heard or own it by now. This item was recommended to me by Corey a while back knowing my fear of table saws. I have found that this thing is always in hand when I turn my machines on and with good reason after seeing Corey's finger today. While I had it in my hand a little light came on. This device is already 95% of the makings of Bj's jig. All it needed was a little planning and very light modification to have that box joint push block I have been envying for the past couple of months. This saved me hours of making a jig and then having another item to have to find a place to store.

I will share a few pictures below. The first picture is the Grr-Ripper in all it's glory and it's standard mode. The other pictures show the way I configured it by simply re-arranging the standard configuration which this tool is designed to do. After that, all I had to do was take a piece of scrap and make the face plate and mount it to the Grr-Ripper. You can see how the middle rail is adjustable and will adapt to any size box joint jig you happen to want to use. It only takes about a minute to configure back to the orginal tool or back again to a push block. If any one has the Grr-Ripper and wants to go this route, I'll be glad to help with any questions or further details.

Works great and kudos to Bj for his original idea.

Hi Bob

That's a great way of doing the same job

I guess I need to take a hard look at one ,I have seen many using it for many woodworking jobs..

Safe is for ME

Corey,

It slides quite well on the box jont jig base. That plastic that OP uses is some slick stuff and allows a nice glide even for the Grr-Ripper. Do consider one Corey, it is a fantastic device. I am pretty sure there is a 2nd one coming my way as it was on my birthday wish list

Bj,

Same to you bud, get one! How much is a finger worth? BTW.... I plan on re-doing the face plate and make it a little shorter and finished looking. This was really a proto type to see if it worked and it did.... VERY well I might add. Thanks for your original idea and inspiration.
