Anyone bolted their circular saw, upside down, to the underside of a workbench??
I don’t think many things are too dangerous for me to try but this is one thing I just know will result in a visit to A&E or the coroner.
You won’t have a guard and you may not be able to keep your fingers away if it kicks. You won’t be able to stop it very easily either.
Having said that my Festool saw’s manual gives a how-to guide, but I closed my eyes and pretended not to see.Posted 3 years agoandysredminiMember
I bolted my circular to a piece of chipboard then screwed that to my workbench.
I cut a slot in the chipboard so the guard and blade stuck through and made guide from a piece of timber and 2 clamps. I wrapped tape around the switch and turned it on and off at the plug.
It worked perfectly but I hated using it and wouldn’t recommend it. It always felt dangerous.
If you do do it just make sure you use push sticks instead of fingers to feed the wood through.

Not done it but there are lots of good YouTube videos explaining how to do it.
(For some reason I like watching woodworking videos on youtube – I have no idea why)
Matthias Wandel is always entertaining:
Loads of detail and links on his website here:Posted 3 years ago
Yeah Matthias likes to engineer things. 😀
He does raise good points though – how will you make sure it is perpendicular? How will you adjust depth or angle?
Check his website though, he links to a bunch of other homemade table saw videos – some have a more straightforward approach.Posted 3 years agoernie_lynchMember
Yes I’ve done it many years ago on building sites (I wasn’t the only one).
Well it wasn’t exactly a workbench it was just something you knocked up to fix the upside circular saw to – a table shaped object.
It works surprisingly well, the slot for the blade is made by simply plunging the circular saw, and the guide is just a length of timber screwed down.
And the switch has to be jammed on, so make sure you can quickly unplug should things go wrong.
Obviously it works best for repetitive rips as the guide can’t easily be moved. And not having any guard or being able to quickly switch off is obviously a little dangerous.
I would suggest screwing the circular saw to the bench even if you have to drill holes into the base as I wouldn’t trust clamps not to suddenly release without warning due to prolonged exposure to vibrations.
Better still buy the right tools/kit.Posted 3 years agotrail_ratMember
Still trying to work out how its any different to my table saw….. Manufactured 1992
No guard on that.
Provided the things bolted down propper- wouldnt clamp it or even screw it and the bench is substantial id do it.
But i dont have to, i have an elu.
( and all my fingers , toes and other appendages- some folk just shouldnt be let near bladed tools)Posted 3 years agosquirrelkingMember
I have one of these:
Got it off fleabay from a builder for about £20. As long as your alignment is good then it works fine. Big stop button controls the power but you do need to frig the trigger on the ripsaw to stay on whilst you use the table switches to run it.Posted 3 years agomaccruiskeenSubscriber
More importantly, has anyone done this and still have their compete complement of fingers left?
Are you expecting anyone to be able to type a response? 🙂
It wouldn’t be any more dangerous than a regular bench saw if you included the features that a bench saw has – which is a guard for the blade (which shouldn’t be too difficult to achieve) and a means to stop it quickly. You can get in-line no volt release switches which you could screw to your bench in an appropriate position. But the circuitry of the saw is part of that two. A bench saw (if its been manufactured in the last decade or so) should actively stop the blade in a few seconds, rather just turn off the power and leave the blade spinning. Your circular saw might do that too – but it uses power to do that, so releasing the trigger will stop the blade, but pulling the plug (or using an in-line switch) might just leave the blade spinning.
You also want to create a reliable fence and maybe a mitre guide.That and making sure the saw is attached firmly enough and straight enough…. means you’ve sort of gained a bench saw and lost your circular saw – getting it set up and working well enough to be be properly useful rather than a quick bodge would mean you wouldn’t want to un-set it very often.
The other question is – are you going to use it for? Since I bought a rail saw I’ve almost never switched my bench saw on – I only use it for cutting repeated batches of material. For everything else the rail saw is quicker, easier and more accurate. Its also more space and effort efficient. If you want to cut an 8ft sheet you only need yourself and 8ft of clear space – with a bench saw you need 8 feet in front of the blade, 8 feet behind the blade and two people to handle the board.
You can make your own rail saw in about 5 minutes.Posted 3 years agomolgripsSubscriber
I bought a table saw at considerable expense when doing 4 rooms of hardwood floor in our new house. It saved a shitload of time. I use it now and again and it terrifies me. I always wear short sleeves and treat the thing with a great deal of respect.
There’s no way I’d bodge one. Very dangerous. I only know one person who’s properly injured themselves with a machine tool and it was a table saw.
Anywhere near South Wales, PLEASE borrow mine!Posted 3 years ago
