I am currently building a Sig 1/4 Scale Cub. I am trying to stay away from CA if possible. I am using a good grade of Cabinet Makers glue. (Aliphatic)

My question is the problem of set time, of course CA is almost immediate and at least 30 minutes clamped with the other. I am building fuse sides and not often am I able to employ clamps very well so I then revert to CA.

Is there as clamp type or are pins enough to hold the sticks in place for the glue to setup? Or is there another trick or special adhesive? I read of people using this type of glue but clamping is not always easy.

Thanks for any feedback. I really hate using CA.. but maybe that is the only choice.

Graham, if you hate CA because of the fumes, there is odourless CA available.

You could use the carpenter's glue and then just a spot of CA to hold it in place until the carpenter's glue sets up. Spring type cloths pins work great as small clamp in awkward places to hold things together.

There are many ways to "clamp"

A combination of rubber bands with scrap wood can solve many clamping problems. band or belt-style clamps can address many situations, T-pins on a hard surface can serve as a clamp/jig. In some cases I may be forced to construct an ad-hoc jig.... I build almost exclusively with Lepages' "yellow carpenter's glue".

Thanks Guys.. I guess I just have to be more innovative. Ron the CA fumes are terrible..but the stuff on your fingers is a pain, (no rubber gloves thanks). Gary will try that, I am working on the fuse sides.. so some of the angles are bad for clamping, it will hopefully get better.
Jim, quite the clamping effort there, I better get some more pins.

That was actually an exercise in laziness.
The 'proper' way would be to cut a jig to fit the inside of the rudder and use a band clamp around the laminations....

When I was framing up my clunk I used a lot of small pins which where mentioned but another item I used was a good brand of masking tape. Don't get the cheap paper type but the stuff that looks like it is waxed. The stuff I have is 3m automotive and you can put a fair amount of pressure on it length ways. Sure helps in holding planking and stuff. Also works good on coro so the glue does not bleed all over, insert some polyeurathane in a flute then spray a bamboo piece with water and insert and tape over.

Graham.
I just finished building a sig 1/4 scale cub. I find the kit to be very old fashion as there are no interlocking parts. Only butt joint. I used a combination of tools to help me hold the parts together but most importantly you'll find that since we have to cut everything to match the plans, the use of a good bench sander and square go hand in hand to help mate the surfaces square on at any angles. Take the time it takes.
Use lost of t-pins and let things dry before going to the next step. I used a lot of 12 minute epoxi and i re-read the not so clear instructions over and over again and studied the plans over and over to be ready for the next steps. This particular kit is very challenging, almost like building from scratch. Use the glue you are comfortable with and good luck...

hope this helps a little

Hi Jessy... thanks for the advice on the Cub.. yes it is not a more modern kit..as I know them, but I am enjoying the challenge. I am putting a G23 on mine, hopefully that will be enough power. The engine I believe, you looked at before you decided to do the Weedy... came out of Quebec and was on a 1/4 Scale Clipped Wing Cub last year.

Is yours a full wing? If so are you leaving it that way. Mine is a full wing but I plan on clipping it, hope that is not a big deal.

Graham. Try the following sugestion. Take about a dozen assorted rubber bands of various lengths , from two inches to 6 inches long. Choose good rubber ones, not too thick. THEN, raid the wifes sewing box, or Girlfriends, and steal some BRASS dressmakers straight pins. I state brass, as the steel ones break easily. Cut off the points from the pins. Then Bend a HOOK and EYE on each pin.Bend the EYE around the band side. Put at least Three (3) hooks on each band.
USE-- Hook one hook onto the side of the Fuse or whatever your building, and STRETCH the band around to the other side, and hook up with one of the other hooks. If your tension is enough to hold the parts in place-OK. If not, use the third hook to stretch more tension into the band, and place that hook somewhere else. You can also pull in different directions too.
I am 73 yrs young, I started modelling when I was ten. I have always used this method , and never start a building project , unless I have at least a dozen of these Band Clamps in my Pin Box. Once you have tried them, you will see what I mean. Of course, I use other small clamps from Crappy Tire, but these get the most use, believe me. Wish I knew how to send a drawing over the forum. Good luck . TRY THEM. D.B.
