I had good success with Freud Double flute straight bits. 1/8 and 1/16. Great precision.
The I LOVE BEER bottles in the pic were made with a 1/8 in on the left (1/4 in redwood laminated to 1/8 inch ply) Height 9 inches.
The smaller one using a 1/16 on 5mm mahogany.
The max depth per pass I’ve used so far for both bits is 3.2mm.
With the 5mm mahogany, I like to do a least 4 passes to get a nice clean cut to avoid sanding so each pass is about .8mm.
I never use tabs either. The end piece just pops right out.
I have used the Freud 1/16" double flute straight bit to great success. I also have an Amana Tool 1/8" double flute straight, which also works well. I’ve been really cautious with both bits, and only do 1/16" and 1/8" passes respectively.
Your post is nearly a year old, but I just found it. You cut 10 mm per pass with a 1/8" bit? I cooked my nearly new 1/4" 2-flute upcut from maker made (3rd cut) 5 mm per pass at 750 mm/min. The tip is black now. So I now have some rapidfire questions:
What router speed setting are you using and what is your feed rate / speed?
Do you have to sand a ton with the fuzzies on the edges from the upcut?
What grade of 3/4" ply were you using?
At a bit length of 1.5", is there any issue getting down close enough to the work piece through the sled thickness (are you using meticulous)?
How much bit do you chuck in the router?
I don’t think the plunge setup I have will let the router get close enough to cut all the way through 3/4" ply… I’m using a “stock” makermade sled. Any information you can provide would be helpful. Thanks!
since this post i have changed to .27" for 3 passes rather tha .4" for 2 passes. i seam to get a bit more life out of each bit.
What router speed setting are you using and what is your feed rate / speed? 12k-15k i have etselcam set to 50ipm for the feed
Do you have to sand a ton with the fuzzies on the edges from the upcut? a bit. nothing a quick sand wont fix.
What grade of 3/4" ply were you using? homedepo claims it is an acx ply.
At a bit length of 1.5", is there any issue getting down close enough to the work piece through the sled thickness (are you using meticulous)? standard rigid router setup for now. i will probably design a 3d printed version when i find some time.
How much bit do you chuck in the router? i will have to check on that one. i mad a quick jig a while back to set the depth and forgot what i set it to.
i routed out a pocket on the sled for the rigid router base to sit in, i have about .25" of material left. this allows for a bit more cutting depth.
