eflanders,
when I was looking for a sander I wasn't sure which to get.I was looking for either a Delta or Performax.I was lucky enough to find a Delta 18/36 and a Performax 16/32 both used at about the same time. I could have bought the Delta a little cheaper and the larger machine was a plus.I also have other older Delta
equipment that I have had excellant success with so I was really leaning that way.
There is a machine repair business in the area that repairs all brands and does repairs in the field on stationary machinery.I thought it might be worth talking to these guys to get a second opinion before I plunked down the cash.Now we all know what opinions are like and everyone has one. But keep in mind that they sold neither brand.After talking with them I went and bought the Perfomax and after I got it tuned I have never regretted it. Oh it had some problems when I got it. That had nothing to do with the design or quality of the machine.The previous owner had used it very little and never bothered with any of the set up instructions.
I have read about problems with thickness variations and parellelism problems due to the open arm construction and the head moving rather than the table.I haven't seen this since getting the machine properly adjusted.If I am grinding something critical I will make another pass or two when I am close to size without lowering the drum. Similar to a sparkout pass on a precision grinder.If there is a parellelism problem it seems far easier to me to adjust the drum to the table rather than the table to the drum.I adjusted mine using an ohm meter and a pecision ground parellel.And I haven't adjusted it since.You can also use a flash light bulb, battery and some wire. I also removed the spring under the adjusting screw on the motor side and added a couple of ny-loc nuts.In fact, if you do a search on tuning your Performax sander you will find some great info out there.
I have also found that Performax ,now Jet, has great product support. I needed their help in the beginning and the person I dealt with was not happy until I was satisfied with the machine.It took a few calls.
OK Delta guys! Don't beat me too hard. I have Delta stuff that I wouldn't part with. It has been good to me.This is just my experience with Performax.
take care,
Ed
