Title: Part 1: Routing/Milling 80/20 for Festool clamps using an MFS & a 1010
Post by: Cheese on March 02, 2019, 01:35 PM
I have a work bench extension table that's made from 40 series 80/20. I'm also in the process of refinishing a Simpson full view exterior door that I need to enlarge the hinge mortises on. I decided the hinge mortising would be easiest to perform at waist level using the MFS.

Thus, to enable the door to be secured to the table horizontally, on its edge, I needed to remove 2 of the 80/20 legs and route in clearance slots to receive both Festool Quick clamps and a couple of 5/16-18 carriage bolts on "L" handles that attach some angle supports to hold the door.

I decided to use a 1/4" diameter, 4-flute carbide end mill with a 10.8 mm router bushing on the 1010 router. This combination gave me an offset of 2.2 mm per side.
The Festool clamp leg measures .470" wide by 3.750" long.  I converted these numbers to metric and then added the offset of 2.2 mm to each side.
Thus the Festool clamps need a clearance slot 16.5 mm wide by 100 mm long. However, because the 4-flute bit is not a plunge bit, I wanted the MFS to overhang the front of the 80/20 by 10 mm. So I added another 10 mm to the length dimension.
I set the MFS to 16.5 mm x 110 mm and I set the speed of the router to 3.

The MFS is placed over the 80/20 and clamped in place. Notice that it overhangs the 80/20 by 10 mm so that there is clearance for the end mill.

This is the finished clearance slot and the next photo shows the Festool clamp installed.

Post by: Cheese on March 02, 2019, 02:06 PM
One of the things that works out well when using the MFS with 80/20 extrusions, is that the extrusions are slightly narrower (by design) in the slot area. So if it's a 40 mm square extrusion, the slot area will measure 39.6 mm. This means that once the MFS brackets are snugged up on the MFS, the MFS cannot be placed over the extrusion. Rather it has to be slid on the extrusion from the front. This makes the connection between these 2 items more secure. A single clamp on the top of the MFS secures everything.

This shows the MFS clamp on the 80/20 from underneath.

[attachimg=1]

This shows the clamp and the 80/20 in contact with one another.
[attachimg=2]

This shows how little the 80/20 can move away from the MFS clamp. That sliver of light is maybe 2 mm. You can also check the distance on the bottom of the bracket vs the slot...again, maybe 2 mm of movement.
This makes the machining of the 80/20 fast. Slide the MFS off, rotate the 80/20 to machine a different side, slide the MFS back on and clamp with a single clamp.

Post by: Cheese on March 02, 2019, 02:39 PM
As I mentioned in Part 1, I also needed to slot the 80/20 to fit the head of a 5/16-18 carriage head bolt. I'll spare you the math and just say that it needs a 24 mm x 24 mm slot. Heres a shot of the bolt/handle assembly.
[attachimg=1]

I opened the MFS to 24 mm wide but kept the length to the original 110 mm. I decided to use a wooden stop block in the MFS to limit the router travel to 24 mm. I again wanted to maintain a 10 mm gap for end mill clearance at the front of the 80/20 extrusion. [attachimg=2]

I determined I needed to cut a stop block that was 24 mm x 73 mm.
[attachimg=3]

Using the same end mill and router bushing and inserting the stop block produced this.

Final product for using both clamping elements.

FWIW...I use isopropyl alcohol as a lubricant. It gives a nice clean cut and isn't as messy as WD40. Besides it evaporates.  [cool]

Never thought of using alcohol. The latest addition to my prop kit is a small spray bottle of alcohol from CVS. Very handy and now it will get more use.

Just be careful Michael, nonferrous metals only as it is flammable. And you don't need much. It evaporates fairly slow so a little squirt will last for 20-30 seconds. The upside though is it drys clean.

Sometimes when drilling holes in aluminum, some of the aluminum will weld itself to the drill bit. Rather than removing the drill bit and manual scraping the aluminum off (that stuff is on there), I'll give it a squirt of IPA and between the heat, the vibration and the alcohol, the aluminum shard will remove itself from the drill bit.  [cool]

A very nice illustration and description of a process many 8020 users could apply to their benefit.
One question: It seems the issue of the end mill not being bottom cutting would be mitigated by just plunging the router centered over the slot. This would be useful if one wanted to do the routing without disassembling.

Ya Ron, as I typed that out I had mixed emotions about using the term IPA.  [big grin]

But then I figured heck, if you want to squander your IPA on machining some aluminum...you’re a better man than me...or maybe just less thirsty.   [smile]

Thanks Greg...to your question, that’s the reason I decided to start the routing 10 mm from the end of the 80/20. That gives a nice pocket in which to plunge the router bit and not engage it in the aluminum. A sort of dead zone. Then moving in a clockwise fashion, you’d only be removing a small amount of material. Which brings up a more important point that you’re alluding to.

My real focus in this “how to tutorial” was to provide a “you can do this” moment...I still hate that commercial.  [eek]

With more people using 80/20, this seemed like a useful discussion in how to optimize the functionality of using 80/20 materials. If you’re using 80/20 then you’re also using the slots for clamping. However, butt up 2 pieces of 80/20 material to each other and you lose the access to at least one of the clamping slots.

Another barrier to knock down is that it seems that a lot of people are intimidated by trying to rout aluminum. I consider it to be just another more dense version of wood. Unfortunately, when using a handheld router on aluminum, the sounds are different as well as the tactile feel through the router. There is a cacophony of different sensations that are both new to and disconcerting to the person that may be well versed in using a router on hard wood.

Just my minimal effort in encouraging woodworkers to try something different.

Not that I'm aware of because they really aren't hot and they're also very small. They come off the end mill as a series of very fine slivers.

Besides, it's best to use some type cutting fluid and whether it's AlumaTap, WD40 or IPA, the small chips kind of form a rough slurry and just don't get sucked up for the most part. I'd be surprised if aluminum chip evacuation is any more than 10%-20%.

Here's a photo of the aluminum chips. The photo can be misleading, these little shards are about .005"-.007" thick.

Thanks Vondawg... [smile]  the MFS has been a game changer for me. Like everyone else, I've had to make routing guides/jigs for most of my adult life and maintaining accuracy has always been an issue. Then having put so much time and labor into these guides I can't stand parting with them. So they get saved in a corner of the shop JUST IN CASE I EVER NEED IT AGAIN. [crying]   [crying]

With the MFS I just keep a notebook with the settings used and whatever other pertinent information I need. Pretty simple.

This is the final part in this series. As mentioned in Part 1 this entire exercise was because I needed to hold an exterior door to my workbench.

The lower "L" bracket in place to support the edge of the door.
[attachimg=1]

The lower "L" bracket and the upper "L" bracket in place while the door is clamped to the upper "L".
[attachimg=2]

This general door position makes enlarging the existing hinge mortises easy. Everything is done from above and it's all at waist level.
[attachimg=3]

Of general interest, I'm a huge fan of Starrett flexible machinist scales. I have both 6" and 12" versions and use them constantly for precision measuring. On some projects I'll use them more than a tape measure.

Here's a shot of me placing the edge of the existing hinge mortise 3.5 mm from the MFS. This measurement is being done inside a small pocket, an impossible task with a tape.

[attachimg=4]

The reason this works well is because the Starrett scales are so flexible. In the final photo notice how much the scale is flexing. I've owned these scales for 45 years and have done this type of measurement with them for 45 years. A testament to their robustness.  [big grin] [big grin] [big grin]

@Cheese great tutorial. I need to cut some slots in my assembled sys/mft cart on the front face. Since I cannot enter the slot from the end and will need to plunge I'm thinking of using an 8mm or 1/4" bit that'll fit the 15 series slot.

Assume you are cutting full depth in one pass, just letting the mill side-cut & shave from the slots edge?

It's gonna be fun cutting in a horizontal orientation...

Thanks,

RMW

PS - grab a few of these (https://8020.net/shop/3299.html) and you can use your L-brackets in slots without the carriage bolt clearance:

1. Full depth, one pass. Produces nice little shards. Make sure you don't climb cut.  [eek]  Climb cutting on a knee mill is one thing, climb cutting with a handheld router is another. CW direction. @rst  has mentioned that he uses and likes a Whiteside aluminum bit. That may be in my future.

2. I hear you...better you than me. [big grin]

3. Thanks for that Richard, I forgot about those because I've never used them before. I'm placing an 80/20 order today so I'll add a couple to the order.

Figured out a variation on @Cheese idea on routing out the 1515 slot to get Festool clamps in using some AL cutoffs.

Clamped some 1/4" by 2" strips to the 1515 and a 1/2" by 1.5" chunk for an end stop:

[attachimg=1]

[attachimg=2]

OF1400 with a 30mm copy ring and a 1/4" spiral carbide router bit at the slowest setting.

[attachimg=3]

As suggested I used some Denatured alcohol for lube, cut like butter.

[attachimg=4]

Using the 30mm copy ring gave me a total of 8mm in movement, 4mm each side of center. The 1/4" bit (6.35mm) took ~3mm off each side of the 8mm slot so it ended up ~14mm wide OAL, perfect for the clamps.

[attachimg=5]

[attachimg=6]

20 minutes to gather everything up, 5 minutes to clamp each setup together and 60 seconds for the cuts.

I am loving having a dedicated metalwork table again, the weldtables.com tab/slot tops are brilliant! So easy to use and they handle most any setup you could need for cutting, grinding, drilling/tapping, and of course welding. It's an MFT for metal.

Thanks for the inspiration @Cheese  [thumbs up]

Thanks for the shout-out @Richard/RMW I do appreciate your kind words.   [smile]   My whole reason for starting the aluminum milling thread was to encourage others to branch out and use other materials than wood. Wood, stainless, stone, aluminum, brass, plastics and even carbon fiber can have a positive impact on a wood working project. It doesn't have to be just wood. There seems to be some reluctance/trepidation for people to explore machining aluminum with wood working tools. That's a myth I want to dispell.

I've machined soapstone, slate and NY blue stone with wood working tools. You just gotta-wanna. [big grin]

On a better note...love your welding table. [thumbs up]

Because we only have a 1 car garage and it's stuffed with bicycles, motorcycles, a lawnmower, a snow blower, and Stihl lawn maintenance equipment, I had to put my welding gear in storage.  [crying]   [crying]

I really want to start welding again...FWIW...you may have pushed me over the top to revisit those areas that are so important for the creative process to continue to produce.

Nice photo's too by the way Richard, they make the process easier.

Hey @Cheese might want to take a look around and see if any of the community colleges or high schools offer a adult ed welding class. Our community college has one that meets for 10 3 hour sessions once a week in the evening. Once they figure out you are not going to blow yourself up or set yourself on fire, they let us work on personal projects. There are a few of us that keep taking it again for the shop time.

I really want to start welding again...

Yea so the frames I was making yesterday are part of the 59th re-org of my massive (12' by 10') wood/metal shop caused by the careless addition of the metalworking table and welding gear. In a small workspace a random tool acquisition can snowball unbelievably easily into a situation where you (1) cannot move or (2) have every worksurface covered with stuff.

The welding gear leads to needing a stock of steel standing in 2 shop corners waiting for a rack to be built. To make room for the 24" by 48" table I had to remove 8 SF of cabinets with drawers and relo the fasteners into parts bins in cubbies hanging from the walls. With the cabinets gone there is nowhere for the drill press, disk sander or bandsaw to sit, let alone the 20V SCMS (love that machine) that is sitting on top of the tablesaw, or the 14" metal chop saw or the portaband.

The latest iteration will have a 27" deep worksurface mounted on the rear wall for all the bench tools & open underneath for the tablesaw cart, material storage and seldom used bench machines like the planer. These frames are the first step:

[attachimg=1]

To get there I broke down and did a blocking plan in SU:

[attachimg=2]

[attachimg=3]

The plan is to have the new worksurface along the rear wall, the SYS/MFT cart and welding table on the front/side walls. Perhaps I will finally reach small-shop Nirvana, loosely defined as being able to use my tools/worksurfaces without first having to move something out of the way...

Working thru some coverage issues, may need a variance to expand the shop and possibly build a canopy over the grills and some storage/countertops.

I hear you loud and clear Richard. Move items off the drill press to use it, move items off the metal chop saw to use it (and the metal chop doesn't have much real-estate in the first place  [tongue]), move items off the planer to use it. About the only tools that are safe from being used as available storage space are the 2 bench grinders.

Looking at your welding table made me think about how much some things have changed. The first welding classes I took were at the local Vo-Tech about 50+ years ago. Every welding table there was just a bunch of welded angle iron with supports that used fire brick as the welding surface. What a kluge job but that was the common solution back then.

You got it. In my case the bandsaw (10") is sitting on the Shapeoko3 CNC.

At the risk of totally sidetracking this thread... metal shop for me was first discovered in junior high 40+ ago. With the welding tables you described but oxy/acetylene only. We did have a couple of lathes and the same teacher taught drafting, I took every shop class I could get after that.

These new holey tables for welding seem to be recently DIY-practical, I guess due to lasers & CNC. The machined Strong Hand tables are too pricey (& heavy) for most of us DIY'ers.

In my 20's I started with a buzz box & then moved up to an old Millermatic 175 MIG and did side jobs making/selling trailers and ?? Abrasive chop saw and a 4" angle grinder I had until 20 years later SS Sandy claimed it along with the little 115V MIG I'd downgraded to following my move to the east coast. I'd been determined to replace it and last year grabbed a beautiful Miller 215 115/230 after a long internal debate over MIG/TIG ended with a practical pull the trigger and weld steel compromise. That little machine on 230V will lay down a killer bead on up to 1/4" material even though it rated for less. All this lead to the welding table and my spring-2019 shop-reorg predicament.

I just saw that Miller released a MIG/TIG AC/DC machine for around $3K & buyer's remorse set in. I'd really like to have TIG aluminum capability but that leads to multiple gasses and right back to "where the heck do I put this stuff?".

Ron's right, the only solution is more shop space.  [doh]

Ya I agree 100%...I did that for years when registering for "Machine Tool Process" at the local Vo-Tech.  Because our local Vo-Tech instructor and I both worked for 3M at the time, we became kindered spirits of sorts....and once I proved I wasn't going to destroy the shop and burn down the building I was left to do my own projects.  [smile]

An interesting footnote...I brought in 15" diameter American Racing wheels in magnesium and decided to turn the profile down because they were pitted. Everything was fine until I mentioned that they were magnesium, at which time the instructor went directly to the wall and pulled off a fire extinguisher and he stood in front of me as I turned down the profile on the wheels. Greg later stated that magnesium with the addition of a little water can start a fire that can't be easily extinguished.

I brought those magnesium chips home, started them on fire...what a show...lesson learned.

We have a facility in Chicago - Arc Academy - which is a maker space for welding and metal working.  They offer classes plus you can rent shop time for $20/hour.  Might see if there is a similar facility in your area.

Richard - I just bought the 215 miller as well.  Got the Mig and Tig package.  From what I've read on the AC/DC Mig & Tig they released, the jury might still be out on it.

And given the cost it's neutral if I just pick up a dedicated TIG machine. Probably will take the plunge later this summer after I get the current mess sorted out.
