Build DIY 3D fixture table

I’ll try forcing the carbide harder but spindle speed may also be working against me.

You'll hear it when its in its happy place. That motor will change tone and sound bogged out. I wouldnt even lift up to clear the chips on that thin of plate.

I ran a handful of 7/8" holes into my bench with that same drill. No problems, just let it eat

you know there is a correct tool for the job right?
I know that a Skill saw wouldn't be the first tool I grabbed for the task you are working on

You know that's a purpose made metal cutting Skill saw marketed to do exactly what he was trying to do with it, right?

I apply as much pressure before the motor makes angry-shorting-out-stalling noises. I don’t lift either. Causes problems such as fouling the cutting edge with a chip and then it just starts galling the bore.

12000 series HSS is kicking ass so far. Much longer, consistent chips but hardly a difference in it vs. the Amazon cutter performance wise. S&F had smaller dirtier chips. 12000 Sets over the slug profile without effort unlike the S&F which I had to wiggle the machine a bit for it to settle.

Unfortunately this is the most efficient way of accomplishing the task. Guide, plunge, remove, finish. Averages 1 minute per hole. I think. Wasn’t really watching the time when I just drilled 22 holes.

Dont get me wrong, its still nicer than doin it with a drill bit. But 1 minute per hole on 1/2" plate just seems really slow for an annular

A heavy worm drive skill saw does better than the metal spec ones. Just super hot chips everywhere without the guards. The key is the saw weight to keep it planted and not chatter.

This is my go to.

I have that saw…
What blade are you using for that cut?

That’s the total cost per hole. Start 11 holes utilizing the template, remove template, clear chips and finish the 11 holes without template. See photo a couple posts ago. (#36) Took somewhere more than 20min to do 22. It’ll smoke a hole in probably 10sec or less if it weren’t for all the extra steps. I get it, highly inefficient but the only other thing I can try is a 2” depth of cut tool. Problem with that is it won’t clear the 1” template, so the mag base has to leave the table every hole which requires chip cleaning for the mag base = time consuming.

Dethmachinefab this is a worm drive saw. All 17lbs of it. No chatter. Smooth as glass. Just the blade ****s off in a right hand direction every time no matter what strategy I’ve tried. (Except freehanding a straight line using only my eye sight on the scribe line) Most likely the foot isn’t worth a **** for accuracy either.

I’ll try “freehanding” the cuts for the underside table webbing….otherwise the dirty ol abrasive chop saw will take the job.

ahh gotcha, Was missing that
 
What makes it 3D? I mean aren't all tabled 3D?

My bench has some holes, was half considering welding them up, seem like stuff end up drawn to them and falling through.
I just weld to the table if I need something held in place.

Using a Skilsaw for this job can go to hell. Started fine but 3” in to the cut it wandered off again. Using a precision straight edge and full blade depth. New Diablo wheel. Abrasive cutting sucks but I can keep a straight line with only minor inaccuracies.

Cut belongs LEFT of the scribe 🤬

I tried the Diable blades on my Milwaukee dry cut saw. They aren't good.
The Amazon specials for way cheaper work just as well.

just to be clear
you are referring to the one that is pictured above wondering all over the place?

3D or 5-sided means the table also has skirts with fixture holes. I can combine the two tables via the skirts for infinite combinations. These tables are about constructing within a repeatable/customizable grid quickly utilizing tooling. Great for production runs. Aside from scraping splatter, there’s no maintenance to the surface. My mind is going crazy with all the possibilities and uses this table/system will provide me.

Yes that’s the saw to walks to the right regardless of which side of the foot is against the fence.

My comment back, was in a heavy sarcastic tone FYI

More FYI
When I was in college back when I didn't have tools. I built a really nice trailer using a plain ol abrasion cut off blade in my wood skil saw.
It worked with better results than what it looks like you are getting with a dedicated metal blade

it sucked, but I hate anything that is abrasive tools
 
I hate black boogers!!! All my abrasive cuts happen outside and now I wear a full face mask. Tedious but I’m happy enough with the angle grinder results.

You can find 7” or whatever blade equivalent abrasive wheels?

Seems to me the carbide blades are fine for short cuts where the blade isn’t in the material for long to have a chance at wandering off. Look at all the tool demo videos. It gets one more chance at cutting strap steel but any rate it goes on fbmp real soon.
 
As long as you put the blade on the right way, I'm with Dethmachine. The worm drive worked fine for me in 1/2".

Thread 'Steel Demon for 3/4" plate?'

MIL wants me to cut some 3/4 plate steel tomorrow- she's building a hydraulic press. It'll end up looking like a meteorite if I break out the cutting torch, so how about a 4400rpm worm-drive with a Steel Demon blade?

It says 5800 max, and 1/2"- surely it'll do 3/4 if I don't push it?

Nice tables! What's your plan for the removable legs? Some kinda socket, or telescoping feet?
 
I’m still at war inside my head with the legs so I don’t have a good answer for you. Removable would be cool and give me options. At best it would be a square socket the legs slide into each corner of the table. Otherwise I’m just going to cut the outside corners of the legs for a step weld design. Really poor explanation.

Leveling feet are 3/8” x 6” discs with 1” threads. Big table will eventually get “part time” casters on some sort of cantilever linkage. Smaller table will live on casters.

109 lbs Swiss cheese weight 12lb reduction

Small table parts are complete. Will take shape next week. 299 holes
IMG_3224.jpeg

Large table drilling/parting will be completed this week.
IMG_3217.jpeg

I’m already using the holes for clamping
IMG_3218.jpeg
IMG_3219.jpeg
IMG_3223.jpeg

The stead & fast brand cutters are still kicking ass.
 
279 holes on the latest and probably last cutter I use. (2” DOC)

350 more to go and I’m finished!
IMG_3249.jpeg

Big relief working inside again. 348lbs seen above before drilling. Holes should be finished by tomorrow and side skirts cut off.

Webbing pieces are in the process of being cut.

Legs will be a square socket system under the table. I’ve decided on that.
 
All of the material has been processed. Final dressing and construction next. 32lbs worth of holes from this plate.

Rusty and flimsy free.99 table being replaced. 3/16 top. Some weird stuff. Kills abrasives, never can get a clean surface for a few things I’ve welded to it in the past like the rollers seen. Might see action for a transmission tear down table before salvaging the legs and piece of 2x4.

1,754 chamfered holes
IMG_3285.jpeg

Never realized how small these little air wasting machines were. All table edges treated with a consistent chamfer. If I were to do it again, I’d treat the holes this way. Wish the foot was larger. Pain in the ass keeping the tool on plane against air hose etc. Might purchase or make a table in the future for the tool for finishing small parts.

Before:
IMG_3308.png

After close to 600 holes. Worked fine but slightly slower. 20 sec per hole. Occasional small gold/blue chips. 1.5 gallons of coolant used for 877 holes.

Looks solid. Did you tab and slot it or just lining it up and gluing it together?
