What you could do is make your own bevel washers by cutting from the flanges of channel iron. Just drill your holes before cutting. If there is that kind of stress on the washers, that would be more sound than malleable ones.

 

Why did I never think of making my own washers from channel sometime the simplest thing you can overlook

I had a 10" S beam that I had to bolt onto plates, and didn't have bevel washers. Cutting them is what I did. Worked out good. Is this on your press? Been following it some on GJ.

 

Yep its on my press

If you can find some threaded rod nuts long enough, just cut them in half at the appropriate angle and weld.

 

You will require a mag drill to drill bolt holes in c channel prior to cutting beveled washers from it.
Are you sure these are cast iron?
Beveled washers are very common with the ironworker trade and structural steel erection. I've never seen cast iron beveled washers.

 

Why would you need a mag drill? I drilled the ones I made on a regular drill press. Just drill them before cutting. If I recall the metal is a little sketchy on the washers, but I don't think they are cast.

 

Well here's a picture of some washers that are the same material as my washers, nut sure why it matters but yes I do Have a mag drill.

 

I should add I did spark test them and they did'nt spark like steel or even cast steel.

 

If you've got a spare one you could do a "weldabilty" test. Lay one on a piece of scrap and run a fillet down one side and then hammer a cold chisel in from the opposite side and see how easily it'll break off. Who knows? You might find they'll weld OK.

Not all bolt-houses are the same - nor is the quality of bevel washers.
Your [photo] example is all I have ever seen at industrial-retail outlets.

For: a 'know/spec product', you have to go to a real bolt-house. Said
houses: are not generally open to the public, require an account, only
accept phone orders, may or may not - have will-call; and they want to
sell in keg quantities.

They have all of the goodies - but small quantities can be hard to get.

Search the sights that project type specifications . . .

How many do you need? If tooled, it may [will] be easier to drill & rip a
channel flange than to source a small quantity of spec. material.

Just cut washers from channel legs, drill and tap them and then there is no more weld on weld

Malleable or steel, galvanized or plain.
Although I like the idea of just drilling and tapping a piece of square stock and cutting the correct angle on it because you can make it as thick as you want it for maximum thread depth.

 

I'd weld on a piece of mild steel to the inside of the channel, then drill and tap from the other side. No need to cut any angles, just weld it on. Nothing to warp as you drill and tap after welding from the opposite side.

 

Ya I know, i was looking through my off cuts and C3x4.1 flange is the exact same size as the 1/2" bevel washers so ill just use the channel and make my own washers out of mild steel.

Cool, you won't have any worries with those failing.

 

McMaster-Carr has bevel washers in steel. 5 for $10. https://www.mcmaster.com/#standard-washers/=15u7a26

 

Betcha can't make em for $2 a piece.... unless your time is free

 

Don't care for this tapatalk on this ipad

 

The welds just have to hold the nut and washer in place until the assembly is bolted together, no? Are you worried about the washer cracking right down the middle because of a couple small welds?

 

1/2" hardened steel bevel washers. 31 cents each, says free shipping. HD Supply.

Hard to even think about building your own when you look at this option.
