I have been using my X-carve for quite some time now, cutting all kinds of figures and shapes. All coming out quite nice. Lately (yesterday) I tried making a tapped box with the use of a SVG created at a online generator. The cuts are perfect in shape, however the tabs do not fit tight together. I am using a 3,175mm single-flute bit, which seems to be running smothely through the wood.
Does anyone have any experience with such a problem?
I made a test-cut to make sure it wasnt the generated file which caused the problem. And it was not.
Any help would be appreciated, Thanks
The bit may not be exactly 3,175 mm. If the bit size is off a little, it will make the joints too tight or too loose…depends on if the bit is oversized or too small.
Have you measured the bit?
I had the same thougt, however these Bits are increable hard to measure. I did however try to change the bit size in Cut2D to a few different sizes (between 3,00mm to 3,30mm) and it did not change the outcome. Maybe I should try a different bit that I more easily can measure?
Did you verify the thickness of the plywood?
If you want to know the exact size, drill a hole or cut a slot and measure it. All bits are Undersized.
@NAM37 I did, and it measure 12mm excatly, so that was not the problem
@cncrockstar Thanks for the advice! I made a hole, and measure it for around 3.5mm, quite more than 3.175mm as the seller claimed. I have tried making a new test-example and it fits much better! I will try make a new box later, and see how it turns out
If it’s larger than you expect, check runout. Make sure the but is straight in the collet.
