Title: Wooden Bowls/Corners; How to?
Post by: krusher on November 12, 2010, 08:51:43 PM
Has anyone here built a wood corner? I’m about to get started tomorrow and was wondering if there was anymore insight I can get on my project.

I know this guy has done it but he’s a one and doner.

I found this (http://rampplans.org/forums/?board=news;action=display;num=1116270222;start=) and it’s pretty helpful

I tried S4PS (http://www.skatepark.org/forum/index.php) but you need to sign up to read their DIY forum… I’m waiting for their approval. I’ve read Thrasher’s Ramp Plans and have done some web searching. Is there anything you could add?

What are the secretes I don’t know, the little things that help the build go better?

What are the measurements you take to cut the sheeting into pie slices?

Started but no where near finished. This is how I’m doing it, let me know if you see something wrong.

(http://i161.photobucket.com/albums/t238/joedalton/Mobile%20Uploads/Photo824-1.jpg)

Most of the wood I get is from pallets, dumpsters, and street corners, so I never have enough ¾ ply; I use a sliver technique for the transition panels. When you cut your transitions out of a sheet of plywood, you’re left with something that looks like a skimboard or a long shield; from that shield you can still cut out “slivers” of transitions. I use the slivers to connect to something solid like a wall or another full size transition panel.

(http://i161.photobucket.com/albums/t238/joedalton/Mobile%20Uploads/Photo827.jpg)

I’m doing this by myself so I need to find a way to steady the pieces; I’ve screwed 2X4’s to hold them up for me. I had to use a sliver in the middle of the corner so I’m going to support it with 2X4’s, which I have plenty of.

No where in my searches have I seen anyone discuss the meeting of all the transition panels.

(http://i161.photobucket.com/albums/t238/joedalton/Mobile%20Uploads/Photo826.jpg)

I just started cutting back an inch, then a half-inch, then a quarter-inch, till they were all at the same height where they met at, or touched.

(http://i161.photobucket.com/albums/t238/joedalton/Mobile%20Uploads/Photo828.jpg)

Trying to get them all equidistant, tacked them in so they don’t move and started practicing on my angled cuts

Angle cuts can boggle the mind. The best advice that has always worked for me is to do a chicken scratch on the piece of wood that goes in the direction of the angle you’re going to cut. Also a good thing to do is to work them out on a piece of scrap wood, and question yourself every time you go to do the cut; that’s what the chicken scratch is there for to show you that you are about to do the cut right (or wrong)

That’s how far I got this week hopefully I’ll have it done before Thanksgiving.

Started at it again.

Use your bevel gauge to get the angle and bevel of each side of the piece. In the pictures above they show the guy measuring for the back side of the 2X6 which I find redundant; if you have the measurement of the front and the angle figured out you don’t need to measure the back.

I used my angle cube to make my life easier

(http://i161.photobucket.com/albums/t238/joedalton/Mobile%20Uploads/Photo849.jpg)

These things are about $20 out the door. After I’d get the angle with my bevel gauge I would put the handle on a flat level surface and put my angle cube to the metal part of the gauge and that would give me the number of the angle. Set my saw to that number and cut, no messing around with the gauge and the saw, just set it and go.

(http://i161.photobucket.com/albums/t238/joedalton/Mobile%20Uploads/Photo851.jpg)

It took me a while to figure everything out, it took me about 2 hours to do the top row. I started at the top because they are the longest pieces and if you fuck up you could use your messed up piece for a lower row… like I did with the first piece I cut…

(http://i161.photobucket.com/albums/t238/joedalton/Mobile%20Uploads/Photo850.jpg)

When times are going tough take a break, slow it down, and give yourself time to stop beating yourself up.

(http://i161.photobucket.com/albums/t238/joedalton/Mobile%20Uploads/Photo852.jpg)

Every level of ribs has a different radius to cut out, for me the top row was a 37” radius, the second row was 31” and the next row was 24”. So I would make a mark on the floor 37 inches from a screw tie a string pull it tight to 37 and draw an arc. Make sure you keep the string at the same tension the whole way through. Wrap the string around your marker until it’s at 31 inches and do the next row

(http://i161.photobucket.com/albums/t238/joedalton/Mobile%20Uploads/Photo853.jpg)

The lower you go on your transition the bevel gauge gets too big, just let it hang over and get rid of the scrap wood. Make sure you plot out where every 2X6 goes beforehand so you can have your gauge fall on the lines to get a good measurement.

(http://i161.photobucket.com/albums/t238/joedalton/Mobile%20Uploads/Photo854.jpg)

Ribbed for her pleasure...

It took me 2 more hours to do the bottom 3 rows. Hopefully I’ll have it done before Skatesgiving…

Strug-a-ling...

(http://i161.photobucket.com/albums/t238/joedalton/Mobile%20Uploads/Photo857.jpg)

I'm sorry but this is my first time...

Can anyone help?

I've searched the entire internet with no success when it comes to tips about sheeting a corner. I'll get it sooner or later but much like Nikola Tesla I'm all about "fuck trial and error". If you can find any links to help me I'll be stoked!

I thought I could take the measurement of the width at the top, the length to the bottom or "point", cut the pie piece out and all is good but it's not, for some reason it gets wider in the middle. Now I'm just going to cut the pie wedges bigger then I need and cut it slimmer where I need it. I know there is some mathematical equation that will help, I just don't know what it is

(http://i161.photobucket.com/albums/t238/joedalton/Mobile%20Uploads/Photo859.jpg)

Don't forget to support your deck...

Skatable but not done...

(http://i161.photobucket.com/albums/t238/joedalton/Mobile%20Uploads/Photo867.jpg)

I solved my pie wedge problem with a little math and ingenuity, I call it Balloon Theory.

(http://i161.photobucket.com/albums/t238/joedalton/Mobile%20Uploads/Photo861-1.jpg)

I cut the wedges larger then I need, then draw a line down the middle of the wedge

(http://i161.photobucket.com/albums/t238/joedalton/Mobile%20Uploads/Photo864.jpg)

Then on the ramp I took measurements every 10 inches from top to bottom of where the wedge should go and transplanted those measurements onto the cutouts

(http://i161.photobucket.com/albums/t238/joedalton/Mobile%20Uploads/Photo862.jpg)

Then I supported a bendable straightedge with thumbtacks and drew a line where all the points met; cut it out and you have a wedge fit for a balloon

(http://i161.photobucket.com/albums/t238/joedalton/Mobile%20Uploads/Photo863.jpg)

This took me about 10 minutes to measure all of the pie wedges but I'm pretty good with a tape measure, so if measurements aren't your strong point you'd might be better off with the "cutting where it's needed" style.

I did pretty good with this but I should have cut on the inside of the line to give me some room

(http://i161.photobucket.com/albums/t238/joedalton/Mobile%20Uploads/Photo865.jpg)

The last piece didn't fit so I'd just cut along the seem to fit it.

The final sheeting is a different story altogether and I'm much too tiered to explain, so if you have questions just post them up here... I'll bet no...

(http://i161.photobucket.com/albums/t238/joedalton/Mobile%20Uploads/Photo869.jpg)

Don't forget to fill your coping with foam kids... it's good for the ears...

I forgot to mention that there has got to be a better way to get precise wedges

i saw your youtube clip.    i'm impressed that you figured it out.  i've heard corners are tough. that's why i'm sure there was no input for you, lol!  it looks super fun to skate.

Thanks guys.

I was tiring to get some of the lurkers involved with this one but not one bite. Which surprises me ‘cause Craftsmen are some of the biggest know-it-alls on the planet… I should know, my other nickname is Google

testing... (http://www.youtube.com/watch?v=1TLU2iAYl04#ws)

I'm surprised at how much everyone who has skated this thing is so stoked on it. There is so much wrong with it...

I'm beat up and the sessions are harsh. Kompound opens at 10 on Sunday folks.

Now if only I could get Greg here to take a picture of his coozie...

Turns out when you put a corner to your ramp, people come over, and they bring beer!


Title: Corner Love
Post by: krusher on March 06, 2011, 10:36:53 PM
I put together a vid of people hitting the corner. I hope to do more. There is so much footage but this is what I had in my iMovie. I put it to one of my favorite songs and I'd like to put the whole corner saga to this song someday. I'm over trying to do titles and naming skaters; if you don't know who they are then it sucks to be you. I'm also over HD I just can't wait that long anymore.

Here is some corner love...

bumping this up as i am working on a corner for my garage mini right now.  some good info here krusher.  i'll be sure to use some of your tips.  i'll start a new thread in the next few days here with my build.

Cool thanks. I hope to skate Mental Block some day

There are so many ways to build corners and humps but the people who do it for a living refuse to give up the info.

Hello there, I was the creator of the micro bowl that was in the garage you referenced... sorry I didn't see the post.

Anywho, we took her down and are re-building her in a bigger garage.
(http://i58.photobucket.com/albums/g279/oldmanskater/100_0144.jpg)

Here's look at the bigger corner we had to build from scratch
(http://i58.photobucket.com/albums/g279/oldmanskater/100_0127.jpg)

Here is how I cut the radius into the rib (I found the radius the same way you did/the image in your first post suggests)
(http://i58.photobucket.com/albums/g279/oldmanskater/100_0120.jpg)

As you mentioned, there are a bunch of different ways to get it done, and I think you can't find too much info on it cause it's so damn hard to describe. 

As far as layering - I'm still wondering about that.  When I did mine, I used two different techniques - scribing and overlapping.  Again, pretty hard to describe so I'll try to document when we get to that part of our build.

Although I'd love to take a week off of work and work for free for Team Pain just to figure out how they get their bowls so tight, the one lesson we learned is that don't sweat the smalls stuff.  Once you get it close - whether it be a rib or layer, nail it down.  Once you start skating it, unless it's a major fuck up, you won't notice. 

Krusher, house ramp looks like a blast.
dtotherob, good luck and hit me up with any questions.

thanks Paul!  i will hit you up if i have questions. that looks crazy.  the start was time consuming, but after some practice, i can see it going pretty smooth. 

here's where i'm at right now. we figured out our radius' and measurements and built the top rung.

Doesn't it feel good to get a row done?!?! 

Your method to finding the radius is on point, but it might be easier to reverse it.  Meaning, drop a plumb line along the template where the next rib will fall.  Mark the bottom of the template, then measure from that point to the bottom tip of the template. That's your radius. And it doesn't have to be perfect, just get it close.

Does that make sense?

Post by: one on January 04, 2012, 03:12:25 PM
here's some tips not sure if you know this or not. 

all rib rows are the same radius across

The radius of the ribs is the same as the radius of the transition template if it comes to a point on the bottom.  (easiest)

don't kill yourself on the compound angles if your off a little

ya that does make a lot of sense lol!  not sure why we didn't think to measure that way, but it's worked out.  i have all the radius measurements now.

it felt great to finish a row.  we were stoked. hoping to finish the skeleton tonite. 

thanks again for the tips!

ya each of our radius measuements were a bit different for each "pie piece" so we just went with an average of the 4. i actually don't know what the transition radius is of the ramp.  i freehanded it when i first built it lol!  it seems to be working out just fine. 

thanks for the input though.
