    Water jet cutting of steel/alloy sheet

    Got a need for some shapes cut from 1mm steel or maybe even alloy sheet.

    Have made some sketches of what I need done, and some photo's of what these things need to do for me.

    Any hookups for small quantities of water jet cutting? I mean batches of 10 each sort of thing.

    They are quite small like 180x130 and 230x130, that's mm btw...

    Ideally someone who can also convert my hand-drawn sketches into CAD as well.

    Prefer to give my money to PFers...

    Tried to send a PM to Fondles but he has blocked everyone...

    Easy to draw dxf, from there go to any water cutter as 10 of each is heaps for minimum charge. Prob be minimum 80 dollars I would say.

    $80 for 10 pieces would be do-able.

    But I don't know anyone locally (nor-west Sydney) that does water cutting, guess I'm gonna have to start googling...

    Don't fret, I would not be able to help with either 1mm steel or ally anyways.

    Stupid easy is also sketchup and export to .dxf (2D only)

    (Just make sure to read online comments on how to ensure proper export. Easy, but important to do it properly)

    Also, western Sydney is blessed with tons of places that do this. It's not that hard from the northwest to blacktown/wetherill park

    When I get my final design sketch done (and a test in cardboard) i'll be in touch.

    Man's gotta know his limitations, i'd rather pay someone to do the CAD than spend hours fucking it up myself...

    I'm sure there are plenty of people who can do it but you know i'm not from around here so I don't know who's who locally.

    In a related matter, what's the go with these spot-weld threaded studs?

    I've tried to find a way around using them but seems like i'm stuck with this concept (no space behind for rivnuts)...

    I found an online shop for the spot weld studs https://www.jhpfasteners.com/project..._220-l-en.html but I guess there is a special welding tool needed for them?

    Need four M6 studs, I guess about 16mm long, on each plate that is going to be cut out...

    My Dafra rivnut tool comes with adaptors for rivstuds, but I haven't looked hard to find who actually supplies them.

    I've used Hygrade Laser cutting in Condell Park. They were OK for small quantities but did have a minimum service charge of $80 or something like that. They can do the CAD thing based on a diagram too.
    Sorry, probably too far into the crime zone for you though…..

    Rivstuds! Holy shit! That sounds like what I need!

    Ah, disappointed... I need studs which are flat on the backside maybe a couple of mm at the most, the rivstuds protrude out too far by the looks of things...

    hat are you holding down, Jack? there are a few options , but you are probably best off with press in studs from http://rgafasteners-psm.com/... go through the PSM products on the left side of the home page and look for self clinching fasteners in the sheetmetal fastener section. You really need to use a specialist press to insert them properly , but some simple tooling and a bench vice will still work for short runs

    You may find laser cutting more suitable. Waterjet is slower which equals more time and money. It has a superior finish on thicker material though.

    It's just a little radio module, not particularly heavy. I need to make an adaptor plate which matches the mounting of the original module, the original was bigger (longer) than the replacement unit, so the plate is the outline of the original, and then the new smaller module bolts to this plate, the back side needs to be flush (or within a couple mm of flush) because the original unit was flush-mounted, hence the rivnuts or rivstuds not working. M6 was chosen because it's the standard size for all of the fasteners for this equipment, not because it's needed for strength or load bearing.

    Need to mount the black module where the silver one was, so the plate is the outline of the silver one, but a bit wider to match the width of the black one. Need studs in the plate, to go into slots in the edges of the black module (slots not cut yet)



    Those self-clinching studs http://rgafasteners-psm.com/files//P...inchinstud.pdf look like a real possibility.

    Laser or water, I don't really mind TBH, so long as i'm not cutting & filing by hand...

    If you get stuck sorting the stud issue you could use some ultra low head cap screws and zap em with with a tig, obviously no good if bracket made from ally though.

    How concerned are you about weight? If not so much, what about using a piece of 5mm or thereabouts al plate, tap the holes and use M6 screws rather than studs

    Water jet cutting of steel/alloy sheet

    Need to have the plate thin as possible.

    Will have to be steel, ally will be too soft I think, I made up a prototype of the 2nd design using 0.5mm ally sheet, very easy to cut with scissors and bend by hand, but too soft for a permanent bracket.







    Made a balls up though, should only have three rivnuts in it, not four.

    This sits on top of a phone module





    Rivnuts are ok here, except for where the connector is on the phone module, but three bolts are more than enough.





    Will start on the plain flat sheet bracket this arvo.

    2nd attempt at the folded one came out much better...

    Those forked legs might be an issue if you want that bent by the supplier, with my bender I need 10 mm other wise that will flare out............... nothing a hammer wont fix though.

    Thats how it has to be, so if it needs a little manual manipulation, so be it...

    Yeah just looks very clunky and not thought out from a fabrication point of view.

    Well it could be just a hole rather than cut through, but I think it'll be tough to get a perfect alignment with the holes in the phone module, the bending won't always be mm perfect, also there's not much space inside where the "feet" have to go.

    Yeah+/-2mm is a general rule of thumb for bent parts, my concern is the internal edge of the slot to the bend.

    Anywho good luck with it.

    Hey Jack, see if the people that do your laser cutting can bend them for you so they can calculate the correct bend allowance. finished part should be within .5mm tolerance easily.

    work out what fasteners you are using and make sure they will work with the material thickness you want to use, also check what hole size is required as these are critical for grip strength.

    PM me if you have problems finding someone , I can probably help you.

    Let me know if you have any issues finding someone locally or what quotes you get, I could draw it from measurements, cut, fold and ship them down if you need but it'd probably be a bit more expensive.
