what stops the wood from shooting threw fast from the rotation of the drum

[Matthiaswandel]

Nothing. If you feed it in from the wrong side, it WILL shoot out.

Your website article says the motor RPM is 1750 with 2" pulley on the motor and 5" on the drum. Am I calculating the RPM of the drum correctly? 1750 x 2/5 for a drum RPM of 700? With a 5" drum, surface FPM would be 700 x (5 x 3.14) then divide by 12 for ~915 FPM surface speed. This seems slower than commercial drum sanders (which really means nothing), but I wanted to make sure my calculations/formula is correct. Any help is greatly appreciated.

[Matthiaswandel]

Correct. Commercial machines also have bigger motors.

I think it's great to prove that there are alternatives to very expensive all-metal machines like say, a Performax. It's eye-opening to realize that things like this are possible. And he answered my question in advance about the "give" in a velcro system being a positive, although I do wonder how uniform the final result is.

[Matthiaswandel]

Pat mentioned that it's important to feed the stock at a consistent rate on the final pass to get a consistent finish.

I bet he can create an iPod just from wood..

The answer is just a google query away.

nice machine, you are giving me an idea to create one, thanks for posting.

I still prefer my 15 inches timesaver... !

:P jk'n

One more question if you have the time.

5, Would a 2800rpm 3/4hp motor be better or would that be to much? According to a previous poster's maths that would give a surface RPM of 1465... Would it be advisable?

Thanks in advance.

Thanks for the video and plans, I'm making one and have a couple of (possibly stupid) questions that I'm struggling to find answers to if you don't mind.

1, Do you think a 19mm shaft will be ok? I know that means more truing but would it still be better than Pat's?

2, Would a 19mm shaft fit safely into 3/4" pillow blocks (0.05mm difference)?

3, Will a 1400rpm 3/4hp motor be ok?

4, Did pat give any rough indication as to how long it takes to get a 5mm board down to 2.5mm for example?

Thanks!
