Malahini router or not

Postby Hercdrvr » Sun Jan 29, 2017 10:17 pm

Getting close on my Malahini.
Should I router a rounded edge all the way around sheer? Nothing crazy that would expose the plywood sub-decking,

and will the router make a clean cut as I approach the transom and everything kinda blends together in a rounded shape. What I'm trying to say is , the router bearing won't be riding on a perpendicular surface to the edge it is cutting.

Also, The top of the front seats frame really needs a softer edge.

What do all you wood Picassos out there think? Kinda one of those cuts that would be painful to recover from if it didn't work out.

I was too scared to router much. I hand sanded all the edges on mine. It really doesnt take that long, a few evenings after dinner. Your Malahini looks great!

You definitely need a perpendicular edge to use the router, so that is out. I used my random orbit sander and did it by eye on all the areas where I didn't have a perpendicular edge to run the bearing on. If you want a really consistent edge you could draw a pencil line down the length of the sheer both on the deck and on the side to use as a guide, say 1/8" to 1/4" away from the edge. If you are not comfortable with the sander, use a long sanding block and do it by hand. As Vupilot said, it really won't take long once you get the hang of it. Skip

Another trick for hand sanding a radius is to drill a hole in a block, cut the block leaving 1/4 or a little less of the hole, and glue in some 60 grit. You can also just use the block as a guide.

I used the router some. But, I cut a quarter round from an old credit card as a gage. Then used the belt and RO sanders. As I get close, I find the best gage is to close my eyes and look with my fingertips.

Tried a practice piece and it was a disaster. The 3/8" router bearing was below the 3/8" material so it just dug in. Routers scare me so I put it away and rounded it by hand. That's the way to go.

Routers have their place, but man you can really screw up fast. Boat's looking great!

Ok, time to put this one to bed. Some fluid motion with the RO sander follow up with this kinda rubbery sandpaper that comes on a role and round the edge like shining a pair of boots.

This last 10% of the build feels like 50% of the work. So many little details trying to come together.

Hi Matt - Maybe prior to the RO sander and hand sanding, you could start taking it down with a nice, sharp block plane. I have a Stanley "Sweetheart" good quality block plane and it's true to its name - keep it sharp and don't plane against the grain, just a little at a time... then hand sanding . the RO could put some whoopsies in it.
