I want to shorten my boat trailer so that it will fit in my garage in the winter, It has to be able to be put back together for the summer. Trailer is built with 5" aluminum I-beams running down each side. My idea is to cut the two beams and splice back together with 4 pieces of aluminum channel about 15" on either side of the joints so two 30" pieces would sandwich each of the I-beams and be bolted together so they could be removed once a year. I beam material is 1/4 " and channel to be used just fits inside and is .29" material. Coments or help would be appreciated.
