Anybody use the Auftriib Cramplifier?
Seems about half the weight of the Billy Goat Ascent Plate.
I like the design of the cramplifier, hesitating on the $200 price.
I messed around with Send cut send and built a knock off of the crampows for just over $60. Been meaning to make a dedicated post in the tech forum about it but haven't gotten around to it yet. I made things simpler/cheaper by using a flat aluminum plate as the base instead of their fancy bends.
You could definitely do a similar clone of the cramplifier with a little few more hours of computer drawing and the end product would probably be closer in terms of performance to the original than what I came up with. Cloning the cramplifier would be a good bit cheaper <$40 since you wouldn't need any other hardware.

swissiphic made the dairylanders which are very similar in design out of milk crates from the dairy
I bought carbon sheets, pressed and laminated them into carbon ascent plates for my crampons and boots using a mold a buddy made. Was simple enough, lght, sturdy and they work perfectly l. Cost about 60 bucks in materials.

I'd buy some of those plates if you made some more... they look great
Me too.
So did you buy prepreg uncured sheets and did a vacuum mold?
or already layed up sheets, made a mold and pressed? Wouldn't that just crack the sheets?
Thanks
Me three!
Do they work with your Tx Pros? I have to use the semi-auto toe bails with my Irvis Hybrids and Tx Pros, since the toe lug is too wide for the wire bail.
Also, do you have to re-adjust you crampon length to work with the plates, or is the length the same as without the plates?
Nice work!! Consider me next in line if you decide to start selling some!
Don't think I'll be selling any as with my slow work process my hourly pay would be pathetic. Maybe I should start a kickstarter to fund a press :-p
Yes works perfect with Leopard Leverlock and the lenght is the same with or without.Quote:

SendCutSend puts a pair of those made of of aluminium at $32 shipped which is pretty darn cheap.
I made the file with the free program InkScape and an hour or two of youtube tutorials. Modifying the .svg file is probably best done by changing the coordinates of the nodes that need to be moved rather than any freehand adjustments.
The Crampow knockoff I made used 6061 aluminium at 0.125" thickness which was super burly. My 165# plus gear stomping around on them could not get even the smallest flex or bend. For this next iteration, I am going to do the same alloy but try out 0.080" thickness instead. If you feel like getting fancy with other materials there are lots to choose from but they are all a lot more expensive. The next step up I would consider is getting 0.1" 0.080" 7075 aluminum from Oshcut which would run you ~$45.
Also here is a pair with vertical toe slots that should be more tolerant of different BSLs. Attachment 407527
^ so are you gently bending the left and right borders with a radiused crease ? Or just keeping them flat?
Places that do HVAC systems probably have a sheet metal press brake that could put a clean 90 degree bend along the edges in return for a six pack.
While 1000 Oaks is right, I was just going to keep them flat for simplicity and to make them a bit more packable. From playing around with different versions the crampon teeth seem to give more than enough lateral stability on a flat plate.
Just some updates.
I just got my pair in the mail a few days ago and had a few changes. The toe bail slot works well for petzl irvis crampons but would need to be made bigger (wider-vertically) for BD crampons. The main shortcoming of the initial design is the slots for the vertical boot holding tabs on the heel piece (not the heel bail) were not wide enough so I had to file middle part down a bit. see the photo. I just updated the svg file in the google folder linked below with the changes to the heel and making the toe slot a little wider but probably not wide enough for BD crampons. I used the 0.08 in 6061 aluminum which did have a bit of flex to it by hand. If you are a big dude, I'm 165 and the 0.08 inch seems fine, I might consider bumping up to the ).125 inch aluminum. For editing the svg in inkscape you should be able to select all the nodes for the bottom half of the plate and move them vertically up or down to make the plat smaller or longer depending on your BSL without too much issue.
Here is a link to a photo of what I changed for the next go round. https://photos.app.goo.gl/tN4vYtRE56RTrzJx5
Other than that an around the house test seemed pretty promising. Feel free to let me know if you have any other questions.
Send cut send really likes people to use the .eps format fyi.
Its been dry in EU, but hoping this upcoming system will produce so I can get out on the auftribs. Leopards and Irvis, so no new info on fit, here.
I had outstanding results with Blaster’s design; I took a pair to AK and used em for a solid handful of days going straight up couloirs for hours. Excellent execution, if sendcutsend would bend down the edges maybe a thinner alu would be good, but mine pack so small that i really wouldn’t change anything. Five star design Blaster!

Man that's super cool Blaster! I don't do a ton of booting up pow filled couloirs but at 35 bucks a pair I may as well consider a pair of these!
Thanks, I'm glad they were useful to some folks. Feel free to PM me if you have any questions when making an order. I'm working on some refinements to get better compatibility with BD crampons as well.
This is awesome! Considering getting a pair myself, though I may model them more after the BGT plates (if I do do something different I'll upload a file here).Quote:

Heads up. I own a pair of French made plates, aluminum.
They need to be pretty stiff, because if you climb a couloir, often you need to penetrate the hard layer and you need to kick pretty hard.

Any idea how thick the aluminum is? Looks like the BGT plates are 0.90", so not thaaat much more than the 0.80" from SendCutSend but they do get a lot of additional strength from the bent edges.Quote:

2mm, but pay attention to the shape in the front to penetrate ice

Thanks Rod! Hadn't seen that style of plate before. They also have curved edges contributing to stability I see.
I like them. The strap they use, like the ones on verts really suck.
I replaced them with voile straps, much easier to tighten and take off. And also more secure. Btw, i also use voile straps for my camp crampons, much easier to put on and more secure.

I went out and tried to break my sendcutsent plates with the 0.80" 6061 aluminum today on some fairly consolidated spring snow without any luck. While I'm only 160# before a pack, I did a few hundred feet of aggressive french stepping, which should be where these plates should be the weakest. I didn't get any bending. Pure speculation but my guess is that you'd have to be well over 200# and or really be intent on breaking them to get a failure.
I will say that front pointing is really the best way to use these plates and that has held up super well. The points of the crampon stick out enough for getting through some firm sections. Attachment 418096

2 quick questions:
1) do you think that your vertical design will work with a BSL of 318-325
2) now that you've used them for a little longer, any long-term(ish) issues with them?
Haven’t managed to break them, but I’m only 165# with ski boots on. If you are extra heavy or nervous about that just go with the next thicker gauge metal. I used that for early prototypes and can’t really imagine a scenario where they would break and the user would still be alive.
For a 318-325 bsl you might want to make a longer plate. The notch for the heel bail is only 3 cm long. I’ll make a few more designs for different bsl’s and post them to the same folder in the next few days.
Updated the folder (https://drive.google.com/drive/folde...usp=share_link) with better instructions and there are currently versions for 286+, 303+, and 313+ BSLs. Right now I only have designs that work with Petzl crampons but will get around to BD versions in the next month. Feel free to PM me with questions.
Inflation bumped the cost up to 45-50$ per pair for the .080" thickness $63 for the .125" thickness.
So, I've also been working on something sorta similar! I have the BGT plates, and while I like them, they're overkill for most of what I do. So I put together my own version, made out of Jbond (a 3mm thick aluminum/polyethylene laminate). I took them for a spin Saturday and they worked really well.

I used the strap-on version Saturday, and I'd say they do 85% of what the BGT plates do. The other 15% is due to the lack of crampons. They weight about 200g (way lighter than the others) and pack flat.
They won't be as durable as the BGT plates, which is fine by me, I'm planning on only using them in soft snow, but Sunday I ended up front pointing about 50 vertical feet of rock/mud under facets in them, and while they got dinged up, they still work great.
I make a bunch of art prints on Jbond anyway, so I'm gonna make a run or two of these and sell them for around $30, if anybody wants a pair!
Interested
I'm game for a pair, sounds like they'll work for the 2 days a year I wish I had something like this
I’d probably go for a least a pair, ill also ask around my local crew- might be more interest. I love my full alu ones but they are heavy. Subscribed!
Sent from my iPhone using TGR Forums
I'm also interested. One, maybe two pairs
Also in for at least one pair and maybe two.
Yep, that's basically the perfect use case. I ski <10 days a year where I want plates. And for those days, the other options on the market are overkill. I've got materials on the way, and should be mailing out the first batch between Xmas and New Years. I'll post on my instagram, and in this thread when they're available!Quote:

Instead of the Cramplifiers, Auftriib talked me into getting their Saucers since you add and remove with crampons on. No, I haven't used them yet, yes they are crazy expensive. But they are super light and arrived in only a few days

Do you have a weight for the saucer vs cramplifier?Quote:
