Get an ocilatting tool, electric. Ridgid does the job for tight spaces and has a million diamond attachements/tile. Bag that Says I.
Last time I used my hand was last night.
I will go through my dremel stuff and all the assorted things for that and see if I got something already. Just run a air hose out there. Most of it I can hit with the board sander. But the tight spots I do think I got a head like your talking about. I do have tile tools a saw and what not I will look in that for a tile cutting bit.
Unfortunately as you see the only time I got to do this boat work is early early. Before un named life responsibilities I can't shirk start. It is already out of glassing range now as far as temps in the time frame I got to do this stuff. When I did the stringers it was only 60 when I started and it took forever to harden. Even with it going up to 75 that day.
The high has been 65-70 and isn't happening till I already stopped working. 40's in the mornings now. So for me I am on hold till spring on glassing. And it makes me sad.
Like I said by the time I order some and it gets here it may drop and be snowing LOL. You never can tell about ky. We had 6 inches one year on thanksgiving. Or it could be 70's till X-mas you never can tell around here. But the forecast is cold for now and that isn't a good thing for doing this with supplies that go bad quick. And it is going to get worse before it gets better. I been getting the truck ready for the winter onslaught lately. 4X comes in handy here pretty soon.
But I won't be laying down on it either. I am going to clean this up sanding and fillet it all. Then cut up what I got for tabbing. I got csm out the wazoo now. And maybe enough 1708 for tabbing. Make it up wrap it in plastic and mark where they go. Make my list of the next batch of supplies. Then move on to buffing and cleaning up engine and outdrive parts.
I will figure something out to do. I was screwing with the engine before I joined the forum and found out I needed to literally build a boat to put it in. When the boat was still frozen and I thought the ice was solid wood DOH! as Homer says. I remember I had to heat the boat to get the skiis out of the skii locker to return them to the previous owner. Because they were frozen down. My how things change quick.
I did get alot more done than I though I would this year. Just wasn't quite quick enough.
