Need leveling feet for 8020

[Upcoaster]

Greetings from Washington state!

I’m making extension benches for my miter station out of 8020 and I’m having trouble finding simple leveling feet that don’t cost a fortune.

With the profile I’m using, the tapped hole in the butt end of the extrusion looks to be 5/8”.  Leveling feet with that fat of a shaft seem to be rated for several hundred or even thousands of pounds.  Even lighter duty ones are at least $7 USD. Given that I’m needing Qty 12 for my project, that adds up quick!

Anyone found an economical source for this bit of hardware?

TIA,
David

McMaster-Carr has some,https://www.mcmaster.com/structural-framing

Only inexpensive option that I can think of is a hex bolt and nut.  If you use an inch screw, grind off the grading marks.

Less surface area than a levelling foot, and certainly not swivelling like a real levelling foot.

What extrusion?

I’m not aware of an extrusion (from anywhere) that comes with a “tapped hole”.

80/20 stuff in 1.5” and 40mm comes with an extruded hole but it’s only 5/16”/8mm.
That size extrusion is more than strong enough for shop equipment. Plenty of leveling pads in that size.

Correction: the holes are the appropriate size to be tapped (by you) for 5/16” or 8 mm.

I'm with Michael, I picked up some 5/16-18 levelers from Menards, a pack of 6 for $6.

Just curious how much weight you need to support?

Correct.  Tapped by me. 

My bad on the diameter.  That should indeed be 5/16 not 5/8.  Oops!

Heh, now that I'm into google with the proper diameter, I'm seeing more options that are reasonably priced.
Don't have Mendards in my corner of the planet but I think I'm onto something now.

Sorry for the bogus question, y'all!

[member=70097]Upcoaster[/member] FWIW that doesn't look like an 80/20 profile, I suspect it's some other manufacturer. Also based on your photo looks to be larger than 5/16" that is standard in the 1515 profile.

Perhaps closer to 3/8"?

You are right, it doesn't look like 80/20.    Its got the extra step on T-slot profile, so I would guess that it is Bosch.

The size of that end hole is not just some random size.  It is specifically the tap drill size for a specific thread.  Find your extrusion in the catalog, and see what end thread is available.  But I suspect that hole is for M12 thread.

In between 8mm (5/16”) and 12mm is 10mm.

That’s a Bosch 45mm profile.The bore is 10mm same as the 80/20 version of 45mm.
Not sure if it’s sized for 10 or 12mmm tap but leaning toward 10mm.
The bore of the regular 80/20 40mm profile is sized for 8mm tap so this is probably for 10mm.

I’d use either 10mm or 3/8” leveling feet, or bolts (if the end doesn’t need to swivel to make good contact with the floor).

Bosch 45x45 extrusion is sized to be tapped to M12

(available pre-machined from supplier, or you can do it yourself)

+1 on the thanks to [member=65451]Steve1[/member] !

I got this extrusion second hand and was not astute enough to know it was Bosh or how to find such wonderfully detailed specs.

Once I got out my tap set and didd a few moments of trial and error however, I came to the same conclusion on the 12mm diameter.

For my application, I think these should do nicely.  I don't need thousands of pounds of load capacity for the extension tables at my miter saw station.  This works out to $3.30 (USD) each!  I like that these have a bit of swivel to them but it's probably not super necessary --my floor is overall quite level.
