Zip transom bevel

Postby Flash » Fri Aug 07, 2015 9:08 am

Good morning,

I understand how the 12 degree bevel is done on the bottom of the transom. However, I'm not sure what they mean when they say bevel the side frames 10 %. Any ideas?

Thanks,

Steve

Is that on your instruction sheet? I'm not sure what that means. You will have to bevel the forward frame some during fairing but I doubt they would give a % value for it.

Don't try to "cut" the bevels. Just wait till fairing and make them then.

Steve,

That would be a 10 degree bevel cut on the sides of your transom (both the plywood parts and the side frame members themselves). The bevel would be such that the inner face of the transom would be larger / wider than the outer face.

However, as Bill mentioned, it would be easier and "safer" to just wait and trim that to meet the angle of the sheer and chine during the fairing process.

I had encountered / asked basically the same question & got some good responses. Here's a link to that thread: http://www.glen-l.com/phpBB2/viewtopic.php?f=17&t=26557

Thanks you very much for the help.

It's a sentence at the bottom of page 2 in Building the Zip. It is right by the part that mentions the 12 degree angle at the bottom of the transom.

I missed that on my Flying Saucer and it took a lot of fairing on the transom sides. Speaking of my Flying Saucer, we made it to within 100 yards of Lake Okabogee 4 weeks ago and it's been in the shop ever since. My 1960 Merc 300 wasn't ready for prime time.

Pictures to follow when it returns.

Thanks,
Steve

For what it's worth I did bevel my transom sides 10 degrees, using a monster router bit since my transom was 1 3/4" thick white oak. Theoretically the angle is right, but conforming the side panels as they curve inward at the transom is a PITA!
This is my first, last and only boat build.

I also pre beveled the side to ten degrees however when attaching the side planking the angle was reduced to about seven degrees for the best possible fit, i think its up to the builder on this one, do what your comfortable with, it'll all work out in the end
I cut twice and it's still too short :mrgreen:

Thanks guys,

It sounds like both of you had pretty good luck with pre-beveling. It would have been interesting to see that giant router bit in action. I like the sound of that 7 degree final angle too.

As promised, pictures of the Yellow Submarine II after it's return from 6 weeks in a Lake Okabogee shop.

I started my Flying Saucer on 2/25/14 and finished it yesterday morning. Kathy and I took it on a shakedown cruise on the St. Croix River yesterday afternoon. The Yellow Submarine One was named by the people of Sarona, Wisconsin because it sunk on the 1st day ( approx. 1972 ). Thankfully,
Yellowsub 2 stayed afloat.

During the past year and a half on the saucer, I took 4 months off to build a screen porch, one month for other house repairs and 6 weeks for a partial colon-ectomy.

I am pretty sure that this would have been impossible without the help and support of all of you on this forum. Thank you so much! The same goes for Gayle, John and Darla at Glenn-L Designs. Thank you very much! Without the support of my wife Kathy, family and friends this would be very difficult. Also, I have to thank the neighbors for running to save me a few times from being crushed by 153 lbs. of Mercury 300.

I have already started Frosty's Zip.

Take care,
Steve

Thank you for your kind words.

Roberta, I'm honored that you think I could be in a show with your boat. Maybe the Zip nest year. However, Kathy and I are planning on going to that show and we hope to meet you and see that fantastic Torpedo in person.

Thanks again to all of you,
Steve
