    Thank you for reviving this tread - I have two DeWalt RADS circa late 1970's. Both are great machines and one was to be given to a fellow forumite on my next trip up his way. As it has been a couple of years since I had all my gear tested I think it is well over due to be tested & tagged again.

    I used one last Monday - now you have got my attention.

    Pardon my electrical ignorance.

    Would testing and tagging detect the insulation breakdown?

    When mine went it was in the middle of a job, one cut = fine like normal, next cut = stop and safety switch thrown.

    If the lecky is doing his job it should! QLD Regs are different to other states in that the QLD Electrical Safety Act over rides the harmonized WHS legislation anyway. Under the QLD ESA the lecky must visually inspect the condition of the tool / machine as well as test it & if they were doing their job correctly I think they would closely inspect a 30 or 40 yo machine.

    "Knowledge of, and the ability to carry out, a visual examination of electrical equipment in accordance with AS/NZS 3760."
    "The ability to carry out the insulation resistance tests on electrical equipment in accordance with AS/NZS 3760."
    from https://www.worksafe.qld.gov.au/lice...and-tag-course

    Unfortunately my lecky mate who did all of my electrical work passed away suddenly, sorely missed as a friend and as a very competent lecky.

    Maybe its time to scrap both RADS - both have sentimental value to me as well as still being very useful tools.

    Thanks for that.

    My sparkie is is great and has been helping me out for some 30 years. He is old school and still carries a dustpan and brush which he finishes every job with.

    As to scrapping your saws, perhaps an overly quick decision, if all the bits are there, they still work as designed and you are happy with them then why not keep them especially as they are no longer made. I use mine frequently, fast, reliable, accurate and cuts and lengths are easily repeatable. It has now been 8 years since my motor was rewound and it's still going strong, so far the cost of the rewind has cost me approx $1.00 per week which will get less the longer it lasts. Should the motor go again I think I would fix it again, just put it down to the cost of doing my woodworking.

    Just a thought...
    Regards,
    Bob

    Geez I have an old Dewalt 740 RAS, makes me wonder what the internals would look like, but still going strong (touch wood)

    One RADS had an easy life in a cabinet makers shop, it still cuts relatively accurately. The other is my Dad's saw and worked hard, real hard. It started out cutting wall frames and trenching the 1/2" deep 2" wide housings for studs in the top & bottom plates. It did that for probably 12 years then spent at least 3 years probably more like 5 years (cant say for sure - fading memory) in a commercial truss plant as the saw for cutting all the webs for timber trusses - literally hundreds of cuts per day. Both have well and truly paid for themselves probably ten fold or more.

    My brother in law is an industrial electrician and has motor rewinding experience but unfortunately is 5 hours away. Will see if I can persuade him into bringing the parents in law for a visit and bring his tools too. See what he has to say before doing anything about scraping them.

    Hi Bob & co.,

    So I ended up getting the motor rewind (full service, so new bearings, starting cap & coil rewind + certification) costed and was quoted $380 + GST from EMRS - Electric Motor Rewinds & Services in Smithfield, Sydney. I dealt with a bloke called Michael who was professional, very responsive & a genuinely nice person to talk with. Based on what Bob paid back in 2008 and the quality of customer service encountered, I went with them straight away.

    For anyone who needs a motor rewind in Sydney, this is the website:

    EMRS - Electric Motor Rewinds & Repair Sydney

    I'll let you know how it goes, but so far so good.

    Cheers,

    Olly

    Thanks for the follow up.

    Enjoy using it and make plenty of sawdust.
    Regards,
    Bob

    Hi Bob,
    Well I managed to find someone in Sydney to rewind the 3 phase motor on my Tatry 125 RAS
    It ended up costing $500 which I thought was ok. The guy that did it was great. (Thanks Mario)
    I'm glad I decided to have it fixed after contemplating whether or not to retire it and bin it all.
    I have a fairly new Metabo mitre saw which is ok but using the old Tatry again has convinced me that old is good. (There's hope for me yet)
    Thanks for your help

    G’day Slim,

    Glad to hear that it has worked out for you. My saw is still going strong and will easily see me out.

    If you have a dig around the forum you can find some other threads of mine which may help you streamline some of your RAS bits.

    PS check your PM’s as I have only just found them.
    Regards,
    Bob

    My theory is that the insulation on the motor windings started to breakdown and the resulting increase in current draw and heat cooked the insulation on the connecting wires and probably gave the switch a nice warm up too!

    I'm always amazed at how much it costs to get a motor rewound but labour is not cheap.

    Good luck with it.
