Help with Makercase.com and kerf

[jreif1]

Can I get some help, please…
I’m using MakersCase.com to make a box. I want a snug fit.
My wood measures .131 inches using my calipers.
I have all my dimensions in but when I cut the finger joints are NOT sung. I still need glue.
I’m sure I’m not setting the kerf correctly, but I don’t understand what I’m doing.
Picture #1: My measurements
Picture #2: Cut Compensation Type: none. (This is what I did)
Picture #3: Cut Compensation Type: Kerf set at .008 (This was too tight)
TIA for the help😊

So kerf for different products are ‘different’. If the .008 is too tight, adjust it. You will have to test it as no one will be able to give you an exact correct answer. When you get it perfect, it will work for this board, but a different board tomorrow may require some tweaks.
Glue is a good option if you’re close

Easy Kerf Gauges

Boring, but really useful. Cut them out of the material you want to check. Slot you material into the slots to find the right size and you already have your kerf allowance! The dimensions are correct in the drawing program, but the actual cut sizes will vary according to the kerf of the cut. So if you are looking for a tight fit, just try the slots until you find one that is tight. That is the dimensions you need to use in your drawing program.!

Thx. I cut out the gauge in the wood I’m using. Found that my wood fits into 3.30 snugly.
“That is the dimensions you need to use in your drawing program.” where do I put this number in MakerCase?

Kerf set at .008

If you make a small cut in a corner of the wood you are using you can measure it and get the real kerf. If you are designing without kerf you can do this…

Kerf is my Moby Dick! Can't get it to be consistent on different medium thickness material

If you want it that close reversing it like that is needed. If you want to know the kerf on a single piece of material today. Cut a small bit and measure it then set kerf and cut your design. If you want to set a kerf on the fly in Inkscape you can set your cut line to the desired kerf size, then in Fill and Stroke (Shft+Ctrl_F) set the stroke style to that number and under Path pick Stroke to Path (Ctrl+Alt+C) and you will have two lines and Break Apart in the same dropdown will make them sep…
