Hello,
I am new to woodworking and bought myself a used table saw (record tspp250).
The riving knife is missing, does anyone have a machine like mine and know where i can get hold of one?
 
Prob not what you want to hear but it's not too hard to make one ... if you can cut steel plate. A small angle grinder helps.

First study the saw and make a full-size drawing of the knife, which may or may not have to provide the mounting for a guard. A good material to make one from is a cheap / secondhand circular saw plate, & you'd have to work out the size needed to extract your blank from, & of course the thickness needed which'd be derived from that of your existing blade - thicker than its plate but thinner than its kerf.
 
if you are going to make one- and at longinthetooth says, it is not difficult, then it might be handy for somebody to trace round one for you, so you have the mounting holes etc in the right place.

a metal cutting blade in the jigsaw will also cut it. if you use thin kerf blades, you may well have to make another anyway. i am not sure what the record one is like, but the kity one was pretty chunky.
 
That's cool,
Thanks,
The knife is available from Record, but there is a wait of 6-8 weeks and it will cost over £25+post. I was thinking if any of you guys have one, then you could trace yours with the correct position of the holes and design.

Spent much on the saw already.

thanks
 
I can send you a pattern of mine if you PM me with you address. Note that I modified mine slightly so that the riving knife does not extend above the blade, meaning that groves and rebates can be cut.

You would still need a crown guard for the majority of you cuts though. Have you planned how you are going to do this?

All good advice above.
One way to get the shape and holes exactly right would be to photocopy the RK.
My RK is cut from gauge plate. Nice and stiff and flat and cuttable as long as you don't let it get hot.
My SUVA-style guard is one of the best additions to a machine I've ever made. You can see its predecessor on many of my Youtube vids. The one I have now is more articulated and does a better job of guarding at the end of the cut, which was a weakness in the original design.

Thanks guys,
I have the crown guard, yes, I will use jigsaw with metal blade to cut out RK.

Steve, is the design for your current SUVA guard detailed in any of your videos or available in print anywhere?

Thanks

I thought you'd never ask :)

It's on WE8, Tablesaw Safety Accessories, part of The Complete Tablesaw.

Cheers

tracing of riving knife is in the post. It is pretty simple but if I've missed anything please let me know.

I like this saw but the motor is causing me a few problems at the moment, but that is because the previous owner abused it. It also means I picked it up for £100 so I really cannot complain. Even if I have to give Record £200 for a new motor I think I still got a bargain.
 
While I am on the 'puter.

Steve - I have been looking at your dvds for years now but every time I save up the pennies you release another 3 dvds and suddenly cannot afford the "complete set". I would really appreciate if you put up a table of contents for each dvd so I could better judge which ones I want/need. This comes on the back of the previous poster asking "which dvd do I need to buy to get jig x".

Cheers :eek:ccasion5:

Halo Jones,
No, I don't think you'd miss anything.
I appreciate your kind effort of the RK trace and send. I picked my machine for well over 400, its in good state came with the optional mitre sliding extension.
The setting on dead zero too.

Thanks again
 
It's a reasonable request. I do try to describe each one as accurately as I can, but I admit there is not a definitive TOC. It's not just laziness on my part, honestly! It's that the structure of some of them is such that a description such as "jig for copying templates" or "saw setting jig", whilst accurate, don't really tell you very much. Or at least, that's how it seems to me.
Basically, if you use a tablesaw then you might get something out of The Complete Tablesaw and if you have a bandsaw then ditto The Complete Bandsaw. If you know as much (or as little, depending on your point of view) as I do, then save your money to buy a camera and make your own films! :)

But I'll add it to my ToDo list and see if I can make it walk.

I've not done any filming for over two years now, but I am writing an outline for my next film(s).

Happy woodworking / DVD watching / filming!
