Re: hull extension in progress with picks
ok....sorry i dont have time to post pics.....i have had family in town and have been doing the tourist thing.....
yesterday we rode bicycles from some old train tressels all the way to pentiction....over 80 k on a bumpy gravel and sand rail road path......took 11 hrs. 6 hrs up hill in deep sand and one hour break at the top, and 4 hours down. my butt is so sore i can hardly sit....lol.....i think im damaged for life....
ok....the boat....the transom is cut out .....it is correct for thickness, parellellism and flatness......
for those of you that dont know what that is.....let me give you some quick definitions and explanations....
first.....the hole it self must be exactly in the right spot.
the hole must be cut so that the anti ventelation plate is exactally in line with the keel....or speed/handeling problems will occure.
the hole also cannot be on an angle....as the drive will be tilted either port or starboard.....habdeling problems will occure.
flatness.....the outer and inner surfaces of the transom must be flat...the tollerances for this are in millimeteres....the have to be flat or the boat will leak and your transom will rot!
thickness......the transom must be the exact thickness of 2 inches...this is how much you need for the drive shaft to bolt into the housing and the bolts to go thru.
parelellism....the 2 inchse must be paralell all the way around the area to bolt the two inner and outer plates togeather with out leaks.
now.....my transom was too thick....it was faired from the out side with different thicknesses of fairing compound and on the inside i had different layers of glass!.
frist i cut the hole.....then using a router set to 2 inches....i routered out the inner side of the transom.....
then using a grinder...i ground down the inner part of the hole to the 2 inch thickness....
i used a laminate gauge for the 2 inch thickness.
parelellism was a real pain.....i again used a grinder to grind out the area around the inner plate till it was flat and even....i used the inner plate as a guide for this.
in mechanic school for boat mechanics.....they give you a week to do this on a transom surface that is allready flat and parelell, at 2 inches thick.
i did mine in less than a few hours total working time.
im just about to run to the shop and glass the area with a thin layer of csm for waterproofing the exposed transom wood on the inside....
ill add pics to this post as soon as i have more time....
cheers
