Good shit, if you waft a blow torch over after youve poured the resin at the end prior to letting them set it will get rid of any air bubbles you have left over from pouring and mixing 👍

Nah mate, the amount of silicon and resin he used will have easily cost €100 - but if properly maintained you could get up to 50 castings from one mould, so if you needed a few hundred holds, it might start to be cost effective.

brush it well with a toothbrush, once you cast the mold for first time (with resin), all the sediments will go away

[@vojtechruzicka3271]

Is it cheaper to make your own holds like this or to buy them?

If you are making just few, it will be more expensive to make them. If you plan to have many, it would be cheaper because you can use the same mold hundreds of times.

[@elna_elna]

The hold comes out smooth to me what I need to put on in order for it to come out as rough as in the video?

[@solsticesdw]

the foam texture creates the hold texture

[@kazo0ie]

even if you manage to copy the rough foam it will wear out soon. you need to add micro bubbles ideally or marble dust for a cheaper solution to prevent them from getting polished with use.

[@disposabull]

When you shape the floral foam you get dust inside of the pores, get a can of compressed air and blow the dust off the foam before you cast it for the best texture.

[@KOG.113]

indeed! Microplastics/fibers end into the water supply all the way to the Oceans! anyways climbing resin holds aren't eco-friendly (even though there are some made from biodegradable plastic) perhaps wood holds (from sustainable sources) are the only way to go - The World doesn't need more plastic. As a rock climber I must admit the rock climbing industry is one biggest toxic waste generator.

[@LRTOTAL]

​@@KOG.113 The world needs less plastics in the wrong places (single-use items) and more in the right places (for example the invention of plastics saved the elephants from extinction in 1800's). Also special plastic membranes wrapped around some foods reduce food waste which in many cases would be even worse for the environment. Macro, Micro- and nano-plastics could be problems though. It's going to take a long time but scientists will find solutions. So we have to invest into research! And dispose of plastics correctly! Reduce, Reuse, Repair, Recycle.

[@Phazaar]

@@KOG.113 Why would you want a biodegradable climbing hold? Surely you want a climbing hold that just lasts forever? Like plastic... The 'plastic = bad' mentality is ridiculous short-sighted. Plastic is often the best material for the job, and is almost always eco-friendly if it isn't single use.

[@IshiFrenchy]

I agree with all of us, but a climbing hold don't last for ever, you have to re-texture it. And I don't think that climbing gyms are doing it. They are just buying more and more because of new shapes...and so producing more plastic :/ I also think wood is à really good alternative, and you can use only a thin layer of resin to texture it. But it is much more work for companies

[@TheWoodVeteran]

Seems like you've been doing this for a while and I dont want to assume your lack of knowledge....however I would caution against using either of the two containers that part a or b of your mixture was in by itself to do the final pour. Mixing both in the 3rd bucket was the right move...but I cringed a little watching you pour it back into a container with unmixed material in it. Using a separate clean container for pouring will help minimize any risk of cross contamination and failure of the resin in the small unmixed portions that might get added as a result of doing it the current way. Aside from that critque...loved the video. I dont rock climb but have wanted to build a small wall for my kids who have boundless energy and the trees around here dont cut it. Also great job really hammering in protective equipment. Dont see it enough. Thanks for the content...it was very informational.

[@fedup545]

hi, thx for the thorough tutorial, really helpful. I have a question: which resin should I choose? an epoxy resin (glass and clear) or a polyurethane type? Thx

[@climbingworkouts]

I’d go for the polyurethane

[@mykulpierce]

I want to make a grip that matches the elbow. Specifically the shape of the humerus where it connects at the joint. I've been working on a C shape hand grip to hold onto opponents by this bone and think cross training rock climbing would be great. Any ideas about how to go about accurately shaping the foam for this bone structure?

[@climbingworkouts]

never heard of such interesting idea, you may have to carve the shape manually, 3d print it possibly and make a mold out of it.

[@JD-io6jv]

If you're grabbing someone's arm, any part of it, you're grabbing more muscle and tissue than you are bone. Just use a PVC pipe with a 90 degree elbow joint. It's a few bucks at Home Depot. The harder part will be getting the muscle around that to the correct shape and density. A high density foam with another layer of softer foam might work well. But do not waste time making a realistic humerus. If you only used a "humerus shaped climbing hold" for training (I assume fighting or wrestling), then you are gonna be in for a rude awakening when you grab a real persons arm and it feels nothing like what you've been training with, and your muscles developed incorrectly for it.

[@mykulpierce]

@@JD-io6jv sorry but this is not correct in what I am describing. You can latch the joint itself

[@renate4951]

What are the diameters ( sizes ) of the holes you make in de foam in the beginning?

[@climbingworkouts]

That is 7/16”

[@Xcerptshow]

What is the cost per mold to start? Then per mold once you have all the reusable stuff? When does this become more cost effective than buying?

[@climbingworkouts]

Depends on the size of the hold and the silicone required, but for the molds of this video, you can consider something in between 30 to 60 dollars per mold. So if you are not planning in making multiple copies, it is expensive. The more copies, the cheaper it gets.

[@Yeffer2]

[@brianbuttrick1451]

When making the mold, why did you do it in 2 pours rather than just one? Just curious if there was a reason!

It is so you don't get bubbles. The first layer is to make sure the silicone goes in all the cavities. The second layer is to fill up the rest

Well from what's listed on the comments section you may be able to do 3 or 4 molds of the same size as in the video, and you may be able to get say 16 holds (4 per mold) with the resin, so it depends of the shape and how much you consume.

@@Rockerrobin If you wanted 500 holds you would only make about 50 molds. If you were to buy 10 packs of 50 holds you will get 10 or more of the same hold.

The key thing is you get holds in the shape that you want and can make holds that you will not be able to find anywhere. If you take the numbers that I gave above it would cost you $2,500 USD to buy 500 holds. As for the time, people that would be making their own are the type of people the enjoy DIY.

You can quite easily make holds from... Rock. Sand stone is the easiest as it’s soft but you can use what ever rocks are local to you. 1. Buy some rock locally 2. Shape some holds with chisel and drills. 3. Add a hole as shown in the video for the bolts. Use a glue to add washers for longevity. 4. Bolt to your wall. Tip. If you want tiny holds simply shape then in to larger holds. You could use composite stone off cuts as they may be similar to non composite stones and cheaper and easier to get a hold of... (pun) ;) For reference we do a lot of old quarry climbing where I live. There are a lot of loose rocks and stuff still in the quarry. Use what you climb on out doors to practice indoors. ;) it’s really easy if you find some one to flatten a side and drill them for you e.g. like a local stone mason.

[@baptistem2978]

The idea is pretty good, but rocks might break unexpectedly, and even more if only held by one screw. That's if you want a modular wall, for a definitive one yeah, stick some rocks to a wall!

@@baptistem2978 drilling the rock would be a hassle

[@disposabull]

We have tried that it sucks. The rocks will shatter and rain down on your customers. If they don't shatter they become polished like glass very quickly. The best solution is floral foam/silicon mold/epoxy. The only way to make a better climbing hold than this video is to add a little bit of glass fibre. If you over tighten the hold it can crack, the fibreglass will keep the hold together so the route setter doesn't drop chunks of hold on to your customers below.
