    Default After 12 years, thinking of buying an HSD spindle, change my mind

    Seriously, has anyone upgraded from a PC router to the 2.2HP HSD spindle and regretted it? I never see anyone post about regrets but it's hard to admit to it after spending that much money.

    With my PC router, I typically run in the 2.5 to 2.8 ips range. With the HSD, how much faster can I increase my feed rate on a PRT Alpha?

    Do you notice a definitive improvement in cut/edge quality?

    I do see a lot of posts about how the HSD spindles are uneconomical to repair. What type of service life can I expect? I do run my machine for profit, but only as a side business. After 12 years, I'm getting ready to replace my PC router for the 2nd time. So, I'm averaging around 6 years per router with my moderate usage. Can I expect a single HSD spindle to last 12 years, if a PC router can survive 6 years?

    The pain and suffering to your ears make it worthwhile. Lower RPM torque makes it worthwhile.

    I run my machine commercially and I got 3 years to the day out of my two HSD 1073 MT spindles. They can be rebuilt but it costs as much as a new one. I upgraded to an ATC and I'll never go back to a single tool machine again.

    If you're coming from a router a spindle is going to be a wonderful upgrade.

    I got two PRS Alphas with HSD 2.2 spindles in 2008 for a big cutting job. One of the spindles was replaced maybe 3 years ago, but the other one is still running fine after 13 years. I don't cut continuously but do cut a lot.

    Your mileage may vary of course!

    I ran a 2.2hp spindle for almost 9 years. I was cutting at 6ips in 3/4" plywood in two passes with a 1/4" compression bit. The spindle is SOOOO much quieter. I ran a Shopbot buddy for about 3 months and the router was so painfully noisy. When I went to a PRSAlpha with spindle, I couldn't believe the cutting performance and no noise from the spindle.

    Like Eric, I upgraded to an ATC with a 5hp spindle last year and the difference in power is incredible. Still just as quiet as the 2.2hp. I run commercially as well, cutting at least 700-800 sheets of plywood a year not to mention carving and cutting hardwoods. You will NOT regret upgrading to a spindle.

    I agree with all of the above. You can run it without ear protection most of the time.

    Thanks for all the replies. Can anyone comment on improvements on cut/edge quality?

    Don - Were you cutting at 6ips on a PRT Alpha?

    Don and Bill, glad to hear you had better luck with spindles.

    Agree with what others are saying here too, spindles are great. Do it!
