No fear of Jointer Anymore!

Hi,

This year I brought my professional machinist friend Alan into my shop as I wanted him to make some improvements to my machines to reach a higher ability to hold very tight tolerances. He performed many jobs and built many custom fixtures and tools to that end.

One of the simplest tools he made for me has had a very huge effect not only to my process control but also the safety concerning the use of my jointer and squaring of my point stock.

Last January, Alan built me a two handed push stick device I designed that allows me to guide the point stock through the machine using the two vertical handles which allows me to give even pressure on the table while holding the piece steady on the vertical fence. He also adjusted my jointer with his precision tools.

After going through the planner, the jointer and drum sander the result is point stock squares that are not just perfectly square but are the same dimension when measured on the ends. I just did two ebony squares for my friend Vern yesterday and they were only .001 or .002 off in size measured end to end. He was amazed but I was expecting such a result because of this tools ability for me to control the process of moving the point stock though the machine with ease without the worry about losing my fingers.

Before this tool I would flinch towards the end as I had to touch hold the piece on the fence by hand while sliding it right to left. A regular push stick is no good because the point must be held square with the fence during the entire length of the pass.

I was so scared of this machine, I never wanted to square points and always put it off. My fingers were an inch away from the spinning knives and keeping the piece level against the fence was tentative at best. Now with my two hands on the handles, I love doing this job and seeing the outcome of making great and accurate points is routine and expected.

Anyone who wants one of these or needs any other stuff for their shop can Email my friend Alan:

JMO,

This simple tool has made a great improvement to productivity, repeatability, and safety in my shop. I like my fingers and wish to continue to build cues and play the piano for a long time. The fear factor is gone for me now.

That looks like a nice simple jig that wouild do the job.
I got rid of my Jointer years ago and went the belt sander route.
If I had a jig like that back then I might have kept it. :smile:
 
This was the solution I discovered and used for a long time before devising CNC methods for producing perfect square stock (Note: this one is missing the see-through guard):

Sadly, this machine has been out of production for many, many years - though you can still find them on the used market. Because of the relatively tiny throat opening and the fact that the feed pressure is applied horizontally (insted of vertically as with a conventional jointer) this machine is virtually incapable of munching off fingers. For very small stock a simple feather board and a single push stick guarantees your fingers cannot get anywhere near any serious danger zone.

The main problem with conventional a jointer is that the operator tends to apply pressure against the feed table using his own body weight. If the piece of stock suddenly vanishes - which is the analytical safety test for any hand operated machine set-up - the only place for the operator's hands to go is down toward the blades. And since even the smallest conventional jointers have relatively HUGE throats the user can get a lot of hand into the opening before his reaction time has him yank his hand away. The Uniplane pretty much solves this potential dilemma,

If I had known they were going to discontinue manufacturing this machine I never would have sold mine. Since I did, for quick facing and clean-up passes I built a similar (smaller) device that works great for one-off operations where I wouldn't want to waste time with CNC.

Chris,

My friend squares his stock for Full Splice Blanks on a large belt sander with a fence also and gets great results with the large squares.
