Here is the vise on the slide plate and the range of movement.

 

Next I cut the table plate that material can be clamped on or the slide plate bolted down to.
It is 6"x1/2" flat bar and my bandsaw was almost maxed out. That part right now is 18"long but might get cut down a little. There will be a 6"x6" riser column to elevate the drill. The layout marks for the bolts can be seen in the last pic.

 

The next part is the plate that the magnet will stick to. It is 6"x12"x1". Thinking of putting it on the milling machine and removing the mill scale because it is a little rough.

 

Got some more work done today. Drilled and tapped the work table plate for 1/2" bolts that will hold the riser block. Also put the four 9/16" holes that will attach the whole thing to the base. I am going to put a large clearance hole it if for when I just want to clamp material down but don't know where it will end up yet.

Did get a new hole saw and arbor because I can't justify the $300 2-1/4" annular cutter to make one hole.

 

I added 6 countersunk holes in the vise slide plate to attach it to the work table. The holes are in that part yet because I want to get the drill placement right first.

 

Thanks for documenting the build, looking great so far. Keep us updated on your progress

 

Very Nice!

 

Thanks, I don't think much will get done during the week because I'm very busy at work but I will be sure to post any progress.

Got some more work done today, cut all the parts for the risers and drilled the holes in them. All material is 1/2" thick and the overall size is 6"x6". There are two plates that will be welded inside the frame that is made from the flat bar. The bottom plate attaches to the work table and the the top plate has 1/2" threaded holes for attaching the magnet plate.

This is how the riser plates will go. One is 1-3/4" tall for use without a vise and the other is 2-3/4" tall for use with the vise.

All the parts ground down, washed all the oil off and wiped with alcohol.

All ready to tig them together. The angle clamped across the top helped to align the plates flush with the flat bar. It was kind of interesting getting everything lined up.

One of the welded risers. I will grind the welds down tomorrow to ensure the magnet plate sits flush and the riser is flat on the work table.

Really nice job! I missed this when you posted back in May. Can I ask, what did you use for counter-sinking the holes in the 3rd picture of post #6? I see the annular cutter on the mag drill. Drill chuck attachment and countersink?

 

I used a 1-1/2" 60deg countersink in the drill chuck.
Used a counterbore for the socket head cap screws.

That version unfortunately did not work like I wanted due to poor planing & rushing the layout. Now that I'm starting to get set up in my new shop the revised version is going to be like a regular drill press with a moving table.

 

@ Chris T - your design is awesome! Did you integrate an x-y table into the the design? Looking to move my existing Jancy Slugger Holemaker II rig and transition into a CS Unitec unit to facilitate threading operations and increased DOC and cut diameters. How do you like the CS Unite unit??

 

I am working on a base that is designed like a bench top drill press with a table that raises and lowers to be able to use short annular cutters or long MT#3 drills or a tapping head. The previous design would have required too many different spacer blocks due to the range of tooling the Unitec drill will take so it did not work as planned (figured that out AFTER it was 80% finished).
The new version will have a table that will accept an X-Y table and drill press vise.
I am going to make a fixed height one just for mobile use but it will be sized for annular cutters only.

The Unitec machine is awesome, I now hate using the Milwaukee & Nitto drills at work. The new base is going to have threaded holes so I ordered some spiral point taps and MT#3 tap drivers to use the tapping feature of the drill. Definately get one with a swivel base, you will always wish you had it if you don't. I met the guys from C.S. Unitec at Fabtech and looked at their other drills including the one that runs a 5" annular[emoji3] and they are all high quality. They even have one with an X-Y table built into the drill. The only thing that could possibly limit the versatility of my machine is its size. This only a problem if you are in a confined space or drilling frame rails under a truck.
