I have a shaper that I bought at an auction, it was a company that went into receivership, the shaper was brand new. It was manufactured off shore. I want to check the accuracy of it, can some one tell me what method is the most accurate and easiest for doing this?
Lots of things to check. Table flatness, fence flatness, fence twist, fence perpendicularity to table, and shaft runout. Do you know how to check any of these?
When you say accuracy I'm not sure what besides the shaft run out would come into play . A dial indicator is one way to check run out . It's the only moving part that comes into play for the finished results perhaps you should set up a cutter for a given operation and run it to see for your self.
On top of the stuff said above, look at what kind of movement of the spindle you get when you lock the height. What kind of slop you have when raising and lowering the spindle. Look at the pulleys while the machine is slowing down to a stop, notice any up/down motions.
Thanks for the replies, I never use a shaper it seems, I buy mouldings and I buy doors. I kind of remember checking runout on one 20years ago with a dial gauge of some kind.
A picture of the cutters you made and the material that ran would be quite helpful .
Several basic things to check. Using a dial indicator will tell you if the spindle runs true. Securing a good quality straight edge between a couple spacers on the spindle and snugging the nut, then lower to the table, will reveal how true the spindle is in relation to the top.
There are several other places to check, but these are probably the two most important, and definitely a good start.
When using cabinet door bits, it's critical that the shaper shaft is perpendicular to the table. Otherwise the slots will cut wider.
Thanks for all the help, I checked the spindle with a dial indicator and I was only getting about. .001 movement. I never checked the spindle perpendicular to the table as I ran out of time.
