I’ve just come in from the shop as I need a little LJ advice. I’m building a tablesaw blade holder and need some 5/8” dowell stock or rather slightly less than 5/8” to slip through the arbor hole of the blade.

I need eight 3/4” lenghts of stock which I was hoping to cut from a 2’ lenght of 3/4” dowell stock and wondered if there is a safe way of reducing the diameter from 3/4” to 5/8”.

I was thinking of using a stacked dado head, raising it slightly above the table then rotating the dowell at right angles across the spinning blade, raising the blade until the desired size is acheived. I’m not so sure however if this is safe or feasible solution?

Any thoughts anyone? I don’t need absolute circular perfection, just something to slip through the arbor hole.

OR

Would it just be easier to admit defeat and use square stock with the edges chamfered??

Thanks in advance.

David

Just use 1/2” dowel.

Spin short pieces in the drill press like a lathe and take a file/rasp to it. Or use a chisel to make a makeshift pencil sharpener. Or, really, just do it the way you were talking about with the table saw. Clamp a piece of wood behind the dowel to prevent kickback; other than that it sounds safe.

Rex B has, what I think, the right answer in that you spin a short piece in the drill press and file it down. If you don’t have a drill press, use a hand held drill clamped to a table. If the hand held doesn’t have a 3/4” chuck, which I’m sure it doesn’t, thread a screw or bolt into the dowel end and chuck that into the drill. I wouldn’t use the table saw to do what you’re saying, I think it might be a little dangerous in my opinion.

You could make a 5/8 dowel plate and reduce the 3/4 stock you have available.

You should be able to find 5/8” dowel. Here’s the link to Woodcraft’s dowel selection in the US: http://www.woodcraft.com/Product/2000667/36793/Maple-Dowel-12-Square.aspx

Otherwise, I’d either use the drill and reduce with a rasp or you could build an exotic jig and use a rabbiting bit in your router to reduce the diameter, such as a 1/16” rabbit for a 3/4” dowel or 3/16” rabbit for a 1” dowel (check out the jig I built and have used to crow or other wise route dowel, it’s the last four pictures: http://lumberjocks.com/projects/70532

They sell 5/8” dowels. I wouldn’t personally try any tricks on the TS. You might be interested in getting/making a dowel plate. Lie Nielsen makes one that is pretty sweet.

I have some 5/8 scrap left from my daughter’s shoe tree. Probably cost more to import to England than they are worth ;-( You can have them if they are worth the cost of shipping.

Yeah but can you come up with a way to turn 5/8 to 3/4. Now that would be a tip I’d like to see.

David,

I agree with Jonathan’s recommendation, but with a caveat. I would do it on a router table or shaper with a dado bit. Using a dado blade in a saw may leave grooves in your dowels, just as they do in the bottom of dados. A router bit wouldn’t leave such marks. Don’t know if that is important to your project or not. Good luck.

Cheers!

if you do the saw dado thing
just make sure the ‘outfeed’ side is higher than the ‘infeed’ side
by the difference in the dowel height
as it gets smaller after the saw cut
so it doesn’t drop suddenly
and catch in the saw
as it leaves the ‘infeed’ side

or better still
here is stefangs way
