Following on from my request about the electric motor I took advantage of the vat free offer at Machine Mart.

So, went along and grabbed a 3hp motor, starter and pulley



Got a speed shaft off the net, comes with a small pulley, I made a new arbor to suit the blades I got from ToolStation out of 2" steel bar, bit stronger than that one there..



Made a mount for the speed shaft to fix on top of the horse...



Adjustable mount for the motor...



After getting the maths wrong for the belt managed to get the right one which arrived yesterday...



Blade runs round at 4800rpm and is quite scary to be honest, the motor is just about silent but the blade makes a ferocious noise!

Video of it attacking wood or it didn't happen....

I won't comment on the lack of guard.

It desperately needs a riving knife to stop catastrophic jams though.

(Not a made up term.)

What's your use for this creation ?

I predict a "fxxking saw. I'm off to B&Q to buy one...." thread coming soon along with a picture of some poor soul with a log in his head. Be careful out there!

Do you live near an A+E department? Would it be worth moving to nearer one before you use it in anger?

Nice work but it looks like something out of a horror movie!

Second all of the above.

I used to work in a joiners workshop.

You really don't want to get complacent with a table saw.

You have no guard, no riving knife and no sliding fence for crosscutting.

I bet you're cutting logs with this bad boy.

Can someone go round there and put this man into some sort of protective custody ?

~Or~

Careful now

My table saw at work is just like that, with all the guards removed. I found they got in the way! The biggest danger is someone falling onto it, it really isnt so bad in use. Mines is 2kw so compareable power.

Sorry i know you probably spent ages making the beast, but it reminds me of this.

Yep, one of those log splitters is next

Guard? Whats that?

Riving knife? whats that?

Sliding fence? Its only for chopping pallets up for the fire..

Admire your Locost approach Coozer, but for pity sake be careful with that!!!

It just screams LIMB DAMAGE

If squeamish, look away now.....

Realy repeating substantially what others have said but if you have no experience of table saws you realy dont know what you could be letting yourself into. Regulations that have taken years to write and develop are there for a very good reason and it is no defence to say something like " its only to chop old pallets up for the fire". The rules are the same even if you were making repro Chippendale furniture. How do I know and why am I such a know all? Trained as a cabinet maker and woodworker 45 years ago and been working as a technician in woodwork, metalwork and jewellery in a school and college for 30 odd years!!! (And still got all my fingers!)

Assuming you have any fingers left once the saw and log splitter are finished, you might fancy a go at this

No one has mentioned the dangers of excessive peripheral speed yet. Personally, I wouldn't use it

What benefits is a riving knife behind the blade???

It stops the back of the blade getting nipped and throwing the wood at your head.

A friend of mine lost 1.5 fingers to a table saw with a guard and riving knife fitted just a couple of months ago, who knows what he could have done with that tool. (he slipped was his excuse) Luckily his son was home from college for the weekend and heard him yell before he fainted or he could have been in a lot more trouble. It's knackered him up for his two main hobbies, guitar and tin whistle playing and he just spent a load of money on a Low E whistle.

I applaud your ability to make it, and your enthusiam
and I hate to say it but

the once in a life time you need the machines guard YOU NEED IT BAD
you don't need to wishing you had it
because odds on at the point you have had it

I've used something similar to saw up pallets. It's not my favourite machine and as you say the sound of the blade at speed makes the hairs on the back of your neck stand up. I've replace it with a band saw which is much nicer to use.
The main danger in my experience is twisting (in the vertical plane) of the pallets as you saw them. To avoid this just ensure your table is wide and deep enough to support the width of the pallet and the length as you feed it in( I'd suggest 2/3 of the width/length of the largest pallet you intend to use to one side and in front of the blade, and about 1/2 out the back as ideal) The width only needs to be on one side, I prefer to have it on the right, but its up to you. I'd suggest a riving knife as its only a bit of 3mm steel behind the blade anyway and does stop the blade from getting caught, which damges the blade as well as being dangerous. As for guards, the thing you're feeding in is 5-6 inches high, so if your guard clears that you can get your arm in anyway, so I wouldn't be as fussed as some here. If your table is deep enough in front to support the pallet, you'd have a hard time getting to the blade anyway without deliberately jumping on the table. ALWAYS use a push stick to complete the feed, ALWAYS power off if you get a jam, and check the blades still tight afterwards, ALWAYS stop if the sound of the blade changes when its not cutting- Ive seen a 12 inch blade come off a machine at full speed and it does a lot of damage (That was at a proper workshop with a fully guarded blade, and the blade came throught the 16 gauge metal casing of the saw and embedded itself about 2 inches into the wooden wall). Don't keep going when you get tired, thats when you're most likely to not bother with the push stick etc.

Just be careful

Not sure how much you have spent on this but you could buy a proper purpose made saw bench for a reasonable price £300-400 . This would be fit for purpose and fitted with the correct safety guards, riving knife etc.
I would suggest that if you use this homemade bench you will regret it.
You wont be able drive very well with only one hand !
I split my thumb down the middle working on a fully guarded saw at work which I used everyday.
You do not want to take any risks with this kind of saw. IT WILL BITE YOU.

Mate,

I am in charge of a wood working shop and have four carpenters working for me. Nearly all of our guys have nipped off finger ends or done some damage in the past on fully guarded machines. 50% of the time its the table saw that gets them.

The SECOND you disrespect your saw it will pay you back in kind. By taking fingers etc. Respect it at all times.

I have seen a guy remove the riving blade on the back of a table saw then a hour later another guy came along and put a piece of 2x2 through the wrong way. The blade snapped up the wood and flung it 50 yards across the site.


However I do like the fact that your 'sticking it to the man'

Ok, a couple of mods me thinks.. smaller blade, I went for biggest/best but its scary.. 300mm down to 190mm I think.. I'll also put a riving guard on it and I'm thinking of making the motor pulley smaller to slow it down a bit....

I am sure there are some calculations you can do to optimise the speed of the blade for the size of blade/teeth/wood being cut. Perhaps the blade came with some calcs etc.

Haha, something's thankfully don't change, you're still a crazy bastard! For you to say it's scary means to a normal person it's going to be terrifying

Stay safe mate,do the mods, you know it makes sense.

<<rich,now goes to bed chuckling>>

Cheers

Maximum blade rpm is usually printed on the blade somewhere.
