the keel bolts look new.
if it wasnt for the condition of the nuts, washers and end top portion of the bolts, this whole step would have been have been avoided.

no photo today as i am still head scratching......
ive grinded the bottom of the keel, no bolts are showing, they must be all tapped into the iron....
.....meaning.....ive (literally) screwed myself big time but cutting them flush.
im having a friend weld a rod so that we try and unscrew them tomorrow, if that fails then i guess i need a mag drill, drill it them out, and tap new bolt a size up from the current ones.

i read somewhere that the minimum thread size should be 2.5 x the diameter of the bolts at the minimum. let me know what you guys think

I'd do everything possible to get the bolts out rather than tap new holes because that be easy.
The wooden boat guys on the following thread say at least 1 1/2 bolt diameters plus room for the taper at the end of the tap:

bolts out!!

at least the 6 main ones. 1 inch thick.
the only 2 that i am unable to take out are the 2 that i try do drill out, the fwd one (19 mm) and the aft one (12 mm)
i think i will have to drill them out. not particularly fussy about the aft one, but defo want to replace the fwd bolt

If you have trouble drilling them out, say in case they are hardened steel, you may be able to sister in new bolts in new tapped holes nearby.

i was able to dril them with HSS drill bit. had i kept quiet those bolts would ve been out by now.....
the main issue is to drill it as close to vertical as possible, i bought a portable drill press/guide to help out in the beggining. not really sure if its going to deliver.

i am trying to shy way from sistering, as i would like to use the hole in the keel stub instead of filling it and opening a new one. but perhaps i will have to go down that road.

for the keel treatment my schedule will be:
wire brush it
apply Primocon (1st layer with brush, 2 other layers with roller)
fair it

and after some research decided to actual laminate 1 layer of glass cloth on it
3/4 coats of plain epoxy resin
epoxy primer
bottom paint

the plan is to do it with the keel inverted so i can reach the bottom and sides in 1 go. the top will be done after and overlapping the layers.

this will force me to get a decent rubber mat in which to roll the keel so i dont scrape the products off of it
