    Hi,

    I am building the Adire Aligntment sub. I cant find the upward spiral twist bit at Home Depot, the guy told me it is not very common. What other router bit can I use to cut?

    Also how do I get the edge smooth and nice looking? Thanks!

    You can use a straight 1/4 inch bit. The caps should be cut with a circle jig to come out smooth and nice.

    You can also use a spiral downcut bit. That's what I used for my sub (Hank: is that correct?). I think the spiral upcut will remove sawdust from the groove more effectively and the spiral downcut will make a smoother cut through veneer. I just cleaned the dust out of the groove with a brush... no problem.

    Jeff: Yes, you can use either, but I use spiral upcut and they cut plenty smooth. Upcut action pulls the dust up and tends to pull the router down against your workpiece. I use spiral downcut only when going through veneer, as the cut is shearing downward and cuts the veneer edge very smooth.

    My router accepts 1/2" and 1/4" bits...is one more preferable than the other?

    I would only buy 1/4" shank for smaller bits. For MDF, 1/2" shanks will not break or vibrate. (Yes, I have broken many a 1/4" bit...not fun!)

    Another question although off topic.

    Where can I get the black fabric that goes over my sonotube?
