table saw

[jtd.75]

Hi does anyone have a 10" or 12" table saw (bench) that they no longer use, the motor on mine has burnt out and the company no longer keep spares for it (its over 5 years old). all the ones on ebay are collect iont only!

Hello JTD,

motors are pretty standard, probably as easy to source a new one, try Machine Mart, you'll need the details from your burn out motor, Size, voltage and frame.

Hi Alec already tried them and clarke's (the make of the machine) they say that the modle that I have the motor's are no longer availble as its over five old and that it would be cheaper for me to buy a new one. This would mean that in the last ten years I would have bought three. The first one I got from screwfix and it last 3 years and the gears on the armature worn away and I was told that it would be cheaper to buy a new one, which I did and that lasted almost five years. (3 weeks ago), this time it was the gear wheel that the armature spindle turns. It seems a design (or built in ) fault to get you to buy a new one!!!!!. I know it only cost me me each time over £160.00.

Hello JTD,

did you ask for a motor, or did you ask for a spare motor for your saw. The same sizes and powers of motors have been produced for a long time, they do not really date. (The exception was the change from imperial to metric).
The possible problem is if your motor is a brush motor which may be more difficult to source?

Your last post puzzles me as you now refer to a gear wheel, but your first post refers to a burnt out motor?

Your point about price is valid, they are not made for longevity, or even accuracy, just something that the occasional user will be able to work with and accept the weaknesses.

Hi Alec, not sure if i have already replied to your last comment or not (old age creeping in very fast) when I said burnt out what I realy meant was that the gear type spindle that turns a cog (gear wheel) the teeth on the spindle are broken or worn and on the other one it was the teeth on the cog that broke. I asked in both case for either a new or replacement motor and was told that they no longer do that type of motor any (brush type) and that the new type of motors would not fit !!!! I saw a saw on ebay in bradford which did not sell but I don,t think towing a trailer with my moggy would make there and back from anglesey.

You need to post up a picture of what's gone wrong. I thought these things were generally belt driven ??

[Troutrunner]

I recon my table saw is driven direct from the motor and yes it is just ran out and checked, to raise the blade the winder moves the motor.

A photy would be good.

[jtd.75]

nope they are similar arrangements to circular saw which is free movement along the timber only its upside down in a metal housing. I don't know how to post pic's and yes thats the correct discription

A quick look on Ebay found this one which is knackered too;

As you have already tried two cheap probably Chinese made saws maybe it's time to invest a bit more and get something better?

Tools tend to one of the areas where "you get what you pay for" applies with a vengeance.

How much do you use it?

[jtd.75]

Thats the same as mine and no they don't do spare motors for this modle hence the reason for my off topic request

Can you put photo's on to photobucket ?

[jtd.75]

don't know what you mean by photo bucket

[Troutrunner]

don't know what you mean by photo bucket

If you google photobucket, its a website you can upload and store photo's on, here is a link to mine.

open an account (free) and try and upload a photo from your PC. if you can't work it out I will try to talk you through it

The ebay one says it has a burned out armature - not the same fault as yours? So maybe - you could salvage parts from that one using your good armature - to make a working saw !

[jtd.75]

Hi BMC no can do, as I have already been down that road with my own two, and I was speaking to an electrical engineer friend of mine who works at our local nuclear power station, and he says that the computator and the coil windings should be balanced!! or else it cause's a mismatch and on the grounds of HSE he would'nt advise it. It looks like I will have to save up my pocket money and by a decent one or change my hobby back to tinkering with moggies

[Alec]

Hello JTD,

if it's the same model saw there will be no problems swapping the armature. i don't understand what your friend means that it's inadvisable on safety grounds.
By the way, as a bit of coincidence, I expect he's at Wylfa Head, I used to be at Trawsfynnydd, long since shut down.

I know he use to be one of the shift charge engineers there (i think that was is title). he always says that if something fails then its down to two reason 1 either poor useage or bad maintenance, and things go wrong when people start swopping things around when they don't know what they are doing. as to hse issue if one item is worn and the other was from a burnt out motor then there was a reason as to why it burnt out and i would'nt trust it.like i said i think i will save my pennies up and buy a good one, i have given my children and grand children plenty of tips so heres hoping

[jtd.75]

Hi Alec .i won't give his name but he lives in holyhead and weights about 19 stone and over 6' and he use to be my dc for scouts(over 10 years ago)

[MarkyB]

I've never heard of balancing commutators and windings either.
Maybe on stepper motors? or for use in the nuclear industry?

No doubt he would advise against tinkering with old cars too!

How hard is it to dismantle one of these saws to get the motor and gears out?

I could pick it up from Holloway, remove the bits you need, and post them to you.

Do they have farm sales or general auctions on Anglesey?
You should be able to pick up a proper heavy duty table saw for much less than one of these hobbyist spec ones.

Hi Mark, I do have a friend who goes around all sort of markets, car boot sales and the likes and i have another friend who travel around to steam rallies and they are both on the look out for me. The first guy is a bit of a recycling freek and inventor, quite a number of years ago he made his own wind turbine using various gadgets and runs the lights,pc,tv, and fridge of it. He said to me have I not considered using my moggy as a source for power for a saw. He tells me that in his younger day when he lived in yorkshire he used a old ford pop to cut up trees, its seems that he welded a shaft to the pully ( where the starting handle goes) and the put a pully on the shaft built a cast iron frame, fitted a saw blade and used belts to drive the blade. Now back to my saw when i said ballance I don't think my mate meant ballanced as in weight I think he meant windings and the likes and the amount of turns. I am a retired post office telephone engineer and he just asumes that i understand full what hes on about. Switchboards and candle stick phones I knew about and the old 232 332, with a smackering of the trim phone
