Hold density is just about right at the Dojo now

Winter 2013 Bouldering set up

Our Dojo has about 250 square feet of bouldering:

• ~400 holds
• 3/5s of the holds are home made
• many built in holds, like two hand cracks, a roof flake, finishing rail
• 26 feet wide, 7.5 feet tall
• A full lap across the roof and back across the wall section is about 50-55 feet of climbing

Open hand training holds

1.  Finger bucket for 30 degree and steeper walls.

How to make them.

2. Wider version of same design, placed on roof section.

While reaching up and out from the 30 degree wall below
this type of hold makes a challenging open-hand match.

3.  Same design, but made with round hand rail for 'slabbier' walls.

Rail is flush with backing to make deeper,

comfortable open-hand edge.

4.  Open hand training hold, with thin rail. 

This design uses a pine 2X3, with one corner ripped off;

plus a thin oak molding.

5.  I made about 10 of these open hand trainers to create 

a mini system wall in the kids area of the dojo.

All of these holds are basic edges that are intended to be installed semi-permanently at particular angles, and with one face up.  This is a good solution for home walls because such simple designs are easier and faster to make than general purpose holds, and they can fill in space around the bolt on holds.  While basic edges are "boring" they are the most common type of hold, especially on sandstone, and are a great resource for training.

The last type of the training hold [image 4. above] brings up a couple of general points about hold layout.   In a home wall, you should create spaces that allow you to train in different ways.  The last image shows a small section of slightly overhanging wall above a small angled roof.   This a great place to work on hanging slopers, but thin edges are hard to use here because holds immediately underneath can obstruct access the thin edge or impinge on your forearm.

Placing the thin edge on the face of the sloper means that you can still access the thin edge even with a more bulky hold immediately below it.  Plus, an array of these training holds let you practice similar movements from both sloping and thin open-hand edges.

PVC pinches FTW

I bought two 10ft sections of PVC (3.5 and 2.5 inches), each for about eight bucks at Lowes. I also bought a corner piece of 3.5 for five bucks. I cut them to various lengths with a circular saw, and pre-drilled holes for bolting them up. I used a combination of standard bolts into T-nuts, lag screws and drywall screws to attach them. The holds will flex a bit under load, but so far they seem plenty durable. Notice the extra large washers, and how we stacked the washers to get contact in a wide area. I can’t imagine tearing through the pvc on such large of an area. If someone can exert that much force on a 3.5 inch tube, pulling down on a ceiling they should try out for the role of Mr. Incredible.

Texture is provided by 6 inch, 180 grit, self adhesive sandpaper discs. So far, the discs have stuck admirably well, with the exception of on the curved piece, where the shape prevents us from having sufficiently wide sections. On that section the paper slowly slides down under full load. Another potential shortcoming is that it is likely that the adhesive is temperature sensitive, and might not work very well in the summer. For wintertime bouldering in our garage we seldom have the heat on high enough to worry about the adhesive softening up.
The pipes are a great asset in terms of hold type and in their “feature-ness”. It is great to have a 5ft pinch rail crossing a section of the roof. It allows a more Hueco-type feel for many of the problems, where beta depends on where you choose to use the hold, rather than which hold to use.
I am sure that heavy climbers or extreme dynos could lead to hold failure in gym conditions—but I doubt we will have problems in a home wall, especially because our low ceiling precludes dynos of any size. Obviously—we don’t grab the sharp ends of the pipes. Another reason these holds are good for home walls but not so much for gyms, where you can’t trust folks not to do foolish things.

How are they to use? Effort is very dependent on body position, the closer to the center of your body the harder it is to use the thumb effectively. In cramped quarters they can be a bit tweaky. Gripped wider than shoulder width they feel great—challenging and non injurious. Using the holds builds pinch capacity pretty quickly. During the first week the section on the 60 degree wall seemed desperate, and now it is pretty casual.

More Mojo in your Dojo

How can you get the most out of your home bouldering wall while keeping plenty of extra cash for other key climbing supplies, like chalk and beer?

Mass production of standard holds. Over the next several posts I am going to write up some strategies I have used to get more climbing potential out of our home bouldering wall. Later I might write up some posts about wall design and construction. For now, let’s focus on holds, and three principles to guide us:

1. The more the merrier. Ideally, every available space for a hold will be filled. You want to take full advantage of the space you have constructed.

2. Diversity is good. You want to have a wide array of hold types and sizes to maintain interest and stretch your imagination.

3. Consistent distribution. You want a variety of hold types in all parts of your space, so that hard, medium, and easy problems can cross all areas of the wall.

When do you have enough holds? When you can no longer fit any more holds on your wall. Our dojo is not there yet. Check out this shot.

The prime climbing area on the 30 degree wall is mostly filled with holds. We can squeeze a couple more around the edges, and we need some small footholds added throughout, but besides that, the area is pretty well filled. Notice the hold diversity. We have made an effort to spread small, medium and large holds; downward pulling edges, sidepulls, underclings and pinches; as well as vary how positive the holds are, though we have few true slopers because they take a lot of space and are hard to make at home. The distribution of types is pretty consistent, though at the edges we have placed more of the ‘likely to be used in that spot holds’.

In contrast, check out the relatively sparse distribution in the “kids” area, with the near vert walls and roof. Density could easily be doubled here. Also note that while the slabs hold some variation, the roof defaults to jugs, especially handle bars. The simple reason for this is access, we make the whole wall accessible to the widest range of abilities that we can. Clearly, we have room for improvement. We need more medium and small holds, more directionals, complex shapes, and footholds in this area.

Gym climbers may debate which hold manufacturer is best: SoIll, Etch, Pusher, Metolious, Straight Up (from long ago). But for the home climber, these companies are nice, but none of them can compare to Lowes or Home Depot when it comes to price.
