Anyone able calculate an angle? cnc mess up so need figure what degree riser will fix it

so had a cnc mess up. the guy who runs it and me didnt cop a small slope in the deck when ironicly trying to level out the front truck mount to the back as i had to move it back…kicktail anyway im useless at maths lol its 10cm lenght by 6cm widght with a 7mm depth sloped up to 2mm depth

could you draw me a diagram, I don’t picture it. lol

So what are you trying to level the messed up mounting face to? 0° to the surface of the deck?

Yeah I think so. I used a trig calc lol, I forgot how to do trigonometry, even though I learnt it only last year.

@stormboard1 te calc said the angle is 26ish degrees

If it’s 10cm length and 2mm one side and 7mm on the other, that’s a rise/run of 1/20 To calculate the angle (Ø): use inverse tan or atan on a calculator

tan^-1(opposite/adjacent)=Ø tan^-1(1/20)=2.86° Ø=2.86°

2.86° is the angle you need.

26 is way off man

Edit: This is assuming 7mm and 2mm were measured at the very corner Confirmed on fusion 360 too.


Ahh it’s all flooding back to me now, yeah that 26 I got didn’t seem right. Thanks for correction and how to do the calculation properly

hmu if you need math tutoring, I charge twenty five 30Q’s an hour.


Special or regular ? 2.86 is right

Nah my algebra and all other maths is good, I just usually forget 1 or 2 topics by the next year if I do not use them much. I think I need to reread my notes book. Hmm so 30Qs are the new bitcoin lol

ya tryna get to level 0 degrees 7mm is deepest edge and 2mm the opposite smaller edge

Haha yea I’m joking. I used to go to a Cambridge education based school in Singapore where they teach all the topics in a single year, getting harder and harder every year instead of drilling one topic per year like they do here in the US. That’s how I remember all of my topics. IMO the Cambridge system is way better.

Yes that sounds quite similar to what they do here in Aus. Although they don’t repeat on all subjects just algebra and the common things


I don’t want be insulting, but… come on man, you really need to spend more time typing and proofreading your posts. I had to read it about 5 times to work out what you were going on about because of missing words and a severe lack of punctuation. You don’t need to be a grammar or spelling expert, you just need to read your own post before you post it AND USE PUNCTUATION.


lol fixed 10 char

so 3 degree would be best probaly as they dont sell 2.86 degree risers lol thanks lads
