198cm 110 under foot, 30m radius
I havent posted in a while because Ive been super busy w/ work school and trying to build skis. but here are a couple of new pairs from the past couple of months
http://www.facebook.com/album.php?aid=4 ... =602540836
Here are the cut bases getting edged.
just before top sheet
198's in the press
a pair of 198's on (R), and 179.5's on (L)
Past present and future
tip spacer and wood (bamboo) sidewalls
view of tip
camber and sidewalls
in the line up
Specs on the 198's
Sidecut - 30m - 137-110-129
Running surface - 165
tip / tail running surface 90cm / 75cm
Mold, Adjustable flat mold w/ 21cm radius tip and tail molds
core
2.5-12.5-2.5 bamboo w/ uhmd tip and tail spacer
Ive been stopping the edges just before the tip starts to make a tight radius (as sseen in some pics) Ive been doing this so it is hopefully less likely to delam.
Pressing conditions
garage temp ~ 50 degrees
after I lay up the ski I slide it in the press, inflate the air bag to 70 psi, and let the ski sit at 100 degrees for +/- 15 minutes and then ramp the temp up to 180 with out stopping. In doing so, ive been getting about 3 mm of total camber (1.5 mm per ski) while pressing in a FLAT MOLD. Im assuming If I let the ski sit at a lower temp, like 90 or 85 degrees, for the 15 min period, it would have less added camber. (once ramped from 40 to 180 and got about 1 cm of rocker, friend did a very slow ramp and with about 3 or 4 increments and got about 1 cm of camber)
After letting the ski sit for 15 min at 100 I bring it to 180 and leave it there for 45 to 60 min.
The other pair of skis are 179.5's (180 I guess). Have the same basic construction.
sidecut
136-97-123 - 18m radius in the tip, 24m radius in the tail, w/ radius change under foot.
this ski came out stiff b/c of the core, and is great in hard-pack and carves well. Not sure how I feel about the dual radius sidecut.
core
3.5-13.5-3.5 bamboo w/ tip/tail spacer

clean looking boards, very nice. now they just need some grafics, how about a tiny logo or something like that?! such skis just have to be labeled so that everyone knows who built them
you seem to be a gearslut! what about those wicked bros with the two binders on? are you serious? if yes: i want to see a picture of skiing them!
and what are those planks just left of the bros? black ones with some red cloth in the tip, uncut...

plywood freeride industries - go ply, ride wood!
haha, if you want to see a pic of the bro's being ridden . . . find a picture of last years squaw pond skim. My roomate and I took it by skimming back to back tandem. I think there might be an archived tgr thread floating 'round somewhere.
here is a pic though (I'm riding on the tail end)
Broke Back Mountain . . . LOL
as for the uncut ski with the red fabric . . . that was supposed to be the match to the black ski seen above with the bandana on the tail. It was the ski I ramped from ~40 to 180 that came out with rocker. I didnt really care for the design that much and was just over it, so didnt cut it out. Now it is one of those pre cut displays I guess.
for logo and name, haha, people have been asking me for a while about names and such. Lets just say my creativity is lacking in that department.

Pressed a new pair last night.
190
158-130-(forgot the tail dimension but it is slightly pined)
core - 3.2-12.8-3.2 poplar
mold had 1.5cm of tip and tail camber w/ a flat foot. But I messed up while laying up. Ive been normaly laying skis up in a 45 to50 degree garage and keeping the base warm by having the heater turned up to 100 degrees during layup. when I normally do this the base will usually touch and the edges wont so the edges end up getting a bit warm. I did this again last night forgetting that it was 60 degrees out and not observing the fact that because I was using a different mold the edges were in full contact and heating up to 100 degrees as well.
To make what could be a long story (in lessons of thermal expansion)short . . . . The skis came out with 4mm of camber where they should have been flat, and a bit less rocker than expected.
Going to cut them out tonight and hopefully get them tuned to bring them to mammoth this weekend for a few test turns in some corn (hopefully corn)!!!

Cut the rockered skis out last night. Had them ground and holes drilled this morning (thanks to Village Ski Loft, N. Tahoe). They came out nice. Still having issues w/ epoxy on the bases though (a little sloppy in layup and possible issues of how flat the mold is) (may have relieved the core a bit much for edges too), but the bases are fairly flat.

'builder - thanks, they rode great in the 4 inches of fresh that there was at mammoth the saturday before memorial day. I know 4 inches isnt much to test in, but you could at least feel how they respond well sort of. they rode well in the chop and on groomed as well, especially for a rockered ski, the camber was a happy mistake.
trying to get some sublimated graphics going this summer, got some friends in reno that are going to help out.
