Update for my router.
Here is the latest installment for my router.
I have had a bit of time up my sleeve lately and have been able to work on my Z axis and motor mount. I am going to try out an Onga pump motor for the spindle drive and gear it up 2 or 3 to 1. The pump is 1 Hp and 2800 revs and I would like it to spin the spindle at around 8,000 to 10,000 revs with about 1/2 Hp. I will be using some pulleys and drive belt from an old photocopier.
Just a thought, If you want power supplies and bearings, pulleys, Solid state relays, nice straight shafting, a piece of glass, and maybe even a nice stepper motor then go to your local photocopier supplier and ask them to keep some old ones for you that they are going to throw out. I have been lucky and have even got a $20,000 copier for free that still works and has only done 32,000 copies that had been traded in and couldn't be sold. I use that one inside the office.
Back to the story.
The first photo shows the Z axis with ball screws and nuts and gas springs either side for counterbalancing the weight of the motor (c/o photocopier for springs) At the rear of the cross slide can be seen a piece of 25 x 50 x 3 heavy walled tubing acting as a brace. The Al C section flexes way too much so I have had to counterbalance the forces and I will be adding another later on as it is still not good enough. Probably good for a 1 meter span but 2 meters is too much for it with the Onga pump motor
The second photo shows the motor mount upside down awaiting the pulleys and spindle. In the background is my Mill/Drill and Horizontal mill. The Mill/Drill is a geared head piece of crap because the geared head bends forward 15 thou when raised to the top making it impossible to do accurate work on. Everything I do with it has to be hand finished which is totally frustrating and time wasting.
The third photo is a closer view of the Z axis. 3/4 chromed rod, linear bearings.
I hope this helps someone out and in about 2 weeks time I hope to have it finished and may post a video of the first cut.........if it works.
Now, to get started with the Rutex servo controller and tuneup software.....more fun !!!!!
warm regards

I am not completely useless.......I can always serve as a BAD example.
