=0AHi John,=0A=0A=0A-=0A=0A=0AI have posed this very question to the list previously, with few results. Some of the guys forwarded some helpful information, but it never really gets down to the difficult part, which is forming the brass to the exact shape of the prop in order to match it perfectly. Obviously this has been done countless times in the past, but I haven't been able to come up the secret.=0A=0A=0A-=0A=0A=0ADan Helsper=0A=0A=0APuryear, TN=0A=0A=0A=0A=0A=0A-----Original Message-----

Pietenpol-List: Re: rib jig
Original Posted By: "Bill Church"
I just took some plastic shopping bags and cut them into 2 inch squares and put a piece under each glue joint.- The plastic would pull right off of T-88 and made it real easy to get the rib out of the jig.- A few years ago at the Sun-N-Fun workshop someone made a rib in the jig without any protection under the glue joints, and I'm wondering if they ever got that rib out.BenOn 1/28/2012 11:55 AM, JOSEPH SWITHIN wrote: When you builders made your jigs for doing the ribs, did anyone drill holes at the glue spots so any excess would fall away?

My rib jig was built using a 2 X 8 piece of lumber. Material was removed from the 2 X 8 at the glue joints. I used Aerolite adhesive applying resin on one surface and activator on the mating surface. If using T-88 or West it is good practice to apply adhesive to both mating surfaces.Greg CardinalMinneapolis ----- Original Message -----

Joe, the disadvantage that I can see with a jig having holes at the joints is thatwhile excess epoxy will be able to fall away, not ALL of the excess will dripoff. You will likely end up with a small blob of hardened epoxy that you willneed to remove before attaching the gussets. By using a method like Ben described,any excess epoxy remains flat, making the attachment of gusset platesmuch easier. On the other hand, you really don't need that much epoxy. If you'rea tidy builder, there really shouldn't be much excess glue.For epoxy, I used T-88, which is very simple to mix; 1:1 by volume - no ratiosto calculate, no need for weigh scales. Some people have expressed a preferencefor the West System, but I don't know what the preference is based on. I likesimple, and a one to one mixing ratio is as simple as it can get (for a two-partepoxy).Bill C.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Sat, 28 Jan 2012 11:01:29 -0700Subject: Re: Pietenpol-List: rib jig
