Cutting scarfs
Subject
Tool chosen depends on the size of the scarf. I've use both a router and a power plane, each with it's own jig to make a lot of scarfs on pieces less than about 6" wide. If sheet goods are involved, then the Gougeon Bros have a neat attachment for a circular saw. I would do most anything to avoid a belt sander, they are strictly a PITA except as an abrasive stock removal tool, IMHO. Lew |

My reaction to belt sanders was the same as yours. I'd borrowed a
neighbor's contractor grade unit made it the 1960s and it was vicious. Then, a few years ago, I bought a Ryobi BE-321 and it's one of my favorite tools. Variable speed and a case that lets it be set down on the bench upside down for use as a fixed sander. http://www.ryobitools.com/index.php/.../tool/be321vs/ I prefer the electric block plane for making scarfs in plywood, primarily because I think it leaves the pores open, but the belt sander is a must have. Yes, by definition it is an abrasive stock removal tool, but the flat sole and the variable speed allow quite small amounts to be removed.

I was suggesting that the belt sander will do a good job and if your tool
budget is limited it's more generally useful than a power plane. I've not been aware of belt sanders leaving grit in the victim and if used with a fresh belt, they don't close pores badly. If you worry about nasty stuff a block plane iron might encounter, you can't build boats. You'll be planing the edge of a glass-sheathed panel soon enough. Keep the stone handy.

Also brush sand paper to clean it. -- ------------------------------------------------------------------------------ William R Watt National Capital FreeNet Ottawa's free community network homepage: www.ncf.ca/~ag384/top.htm warning: non-FreeNet email must have "notspam" in subject or it's returned |

Brian, you can't blow out the sanded area with a high pressure air gun? I can't imagine ANY sand or grit being left in a sanded area after a thorough blasting with an air gun using 100+ psi.

Cutting scarfs
People always say that having a belt sander is a good idea, but I have a
good Bosch one that's been sitting on the shelf for years and years, just collecting dust. I find that with my Bosch power hand plane, low-angle block plane, 5" random orbital sander, and 7" random orbital angle sander, that I just don't need anything else. It's very difficult to do a nice job of anything with a belt sander ...very easy to get non-level in one direction or the other and you can't see it happening. Maybe I haven't found the right wood working project to match up with the belt sander? Brian D "Brian Nystrom" wrote in message news:lcpaf.3490$5F3.808@trndny03...

I agree that both are equally likely. Both likelihoods are about zero.

Actually, you're as likely to blow grit INTO the pores in the wood as out of them. |

Cutting scarfs
Here's a free opinion (and I've made a lot of scarfs ...never a failure
either); - I prefer cut pores, not pores sanded and smooshed flat. Use of a circular saw attachment (followed by a low-angle block plane finish) or a power hand plane is what I do in my shop. I want the epoxy to suck as deeply in the wood as possible, and judging by how many coats it takes to keep the cut edges looking wet (3 coats, sometimes a 4th), I'd say that the epoxy is going SOMEWHERE where it's doing some good for the strength of the joint. Right into the pores. - I vacuum scarf joints with a ShopVac prior to gluing. Then I wipe down with a damp hand towel and let it dry for 20 minutes. Then I pre-wet with 3 or 4 coats of clear epoxy, then glue it up with a mix appropriate to the task ...straight silica thickener, or silica plus milled glass fiber. Just my 2-bits. When it comes to scarfing, there are a lot of ways to skin the cat. I've heard of others having scarfs pop open when bending wood around a boat, and wonder how many scarfs 'barely held' on others. That's why I'm careful.
