Popular Post Former member Posted July 7, 2015 Popular Post Share #1 Posted July 7, 2015 My new frame is finally ready to layup the CF around the tube junctions. Tomorrow we will do the layup, stick it in a vacuum bag, and bake it at 250F for 3 hours. Wednesday we'll sand the frame, and prep it for clearcoat. Hopefully the frame will be ready to ride by the weekend. 9 Link to comment Share on other sites More sharing options...

Randomguy Posted July 7, 2015 Share #5 Posted July 7, 2015 About damn time!!!Why only 250F? Link to comment Share on other sites More sharing options...
Former member Posted July 7, 2015 Author Share #6 Posted July 7, 2015 About damn time!!!Why only 250F? Life got in the way. His wife is going through some heavy shit(cancerous tumors on her brain), so sometimes stuff gets put on hold. 250F because that's all that is required for the prepreg to cure, and the vacuum bag will melt at 300F.

Former member Posted July 7, 2015 Author Share #8 Posted July 7, 2015 The frame is wrapped, and curing now. It comes out of the oven at 5pm. Tonight Matt will remove the release wrap. Tomorrow the sanding and paint prep work begins. I'll post photos tonight. The CF wrap looks sweet. 3 Link to comment Share on other sites More sharing options...
Airehead Posted July 7, 2015 Share #9 Posted July 7, 2015 It is kind of like when Parr8 and his wife had their baby-- you need to write long reports about the frame becomign a bike. 1 Link to comment Share on other sites More sharing options...

If I don't like the frame, we can scrap it and start over. The builder is giving me the frame in return for honest criticism of it's performance. 2 Link to comment Share on other sites More sharing options...

Parr8hed Posted July 8, 2015 Share #18 Posted July 8, 2015 The seat and chain stays collapsed. I haven't seen it yet, but they will have to be replaced. Maybe it's that extra 12 lbs you have put on? I am pretty sure that Parr8 can't scrap one of his kids and start over.The Battleship has been decommisioned. There is no starting over. Link to comment Share on other sites More sharing options...

Former member Posted July 11, 2015 Author Share #21 Posted July 11, 2015 Well that sucks.Ouch.under the heat of the curing process they collapsed from the compression of the vacuum bag. I think it was because we didn't bond the dropouts into the stays before curing. His frame is fine, and that's the only variable other than size. When he gets back from vacation we will try it again using ENVE stays, and bond the dropouts in first. Ideally he should try the same stays, and bond the dropouts first, but he eventually wants to use all ENVE tubing. The main reason why we didn't, is that they require dropouts that aren't available from any supplier. The dropouts need to be custom made. Link to comment Share on other sites More sharing options...

Former member Posted July 11, 2015 Author Share #25 Posted July 11, 2015 This failure cost just over $1000 not including labor, but lessons were learned. I love being part of the process because I get a free education on CF frame building. Eventually he wants me to be a frame builder for his company.
