Did not replace the bearings, just used Kublers recommendation and forced the old grease out. Or think I did, can't tell without pulling the spindle apart. Anyway, it runs smooth.
Finally took the time to make this EMA my main profiling shaper with outfeed and infeed rests- takes two 4 1/2" x 2" carbide insert heads, stacked on the spindle. And man does it cut smooth. Way way better than the Felder they were on previously.
And also used the oddball feature, where the...
We have an older RPC (20 years)and the bearings are needing to be replaced.
The machine this powers seems to be vibrating more than it used to. (7.5hp wood shaper). Can this be the RPC? I can't find any obvious bad belt or bearing in the shaper.
Thinking about it, the shaper did not always start exactly the same.
Sometimes it just instantly started up, and sometimes it would chatter just for a fraction of a second while starting. I have not tried but once since replacing the fuses.
OK- you guys are freaking well of knowledge!
Thanks!
I will assume that the fuse was likely degraded over time and use, and replace the other two with new ones also.
I am running a 9hp three phase shaper and just blew a fuse on startup- there is a disconnect switch with three 30 amp time delay fuses. Probably 30 years old.
There was no apparent difference between starting it this time and any time before. Stuck in a new fuse and it works fine.
Just...
I need something stupid easy- really.
I want to draw a 3-0 6-8 door, draw the stiles and rails, have a preset mortise depth added to the rail length, and be able to have a cutlist from that. Or a 36 1/2" door by 81" , and have a cutlist.
Most of the programs are so far over what I need it...
We make custom doors, with fine wood mullions.
Tiny shop, but well tooled for what we do.
We need a basic CAD program- one that will allow us to draw a door, and generate a cut list. There will be some constants, like the depth of a mortise, and some variables, like door size and mullion...
I have have the same unit on the lathe- periodically it will have display issues, or refuse to accept an input. The fix is is to pull out the ribbon cables and clean the contacts with electrical contact cleaner, and plug and pull the ribbon a few times to get any oxidization off the connectors.
I just posted the Acra Turn 13" 4TPI leadscrew threading and feed charts here.
