new tablesaw insert

[devonwoody]

I was out shopping this morning and passed a sign writing shop so I thought I wonder if they do ali. sheeting.
And I got this:

Its an ali./composite (plastic) 3mm thick sheet.

The reason i wanted it was because the existing ply minimum clearance insert has warped and its front edges raised above the table.

Pictures showing the finished plate in place.

didn't get anything done on the chevron box today, giving me set up problems again.

DW, did you cut the riving knife slot by hand or did you flip the plate over?

Rich.

 

[devonwoody]

Why didnt you ask me that this morning?

(I cut it with the jig saw)

BTW, I have been watching some of the old professionals on video and they have all their fingers and no riving knife fitted, I reckon with the strip jig I made the other week I could do away with the knife a lot of the time unless cutting heavy and larger pieces of timber.

So why is then DW that all the new saw tables coming out of the US of A these days make a deliberate feature of being fitted with a riving knife? It's not hard to work out why...don't take off the riving knife - Rob

You're not necessarily going to end up with missing fingers by using a saw without a riving knife but, you will probably have great lumps of timber being thrown back at you at around 100mph! :shock:

Keep your hands well away from the blade at all times (300mm/12" is a very good estimate) and you still be able to complete whatever operation you're doing, all in one piece.

If it looks like you're hands may be too close to the blade, they've shouldn't be anywhere near there!

BTW, I am using a new jig for me that rides along the fence and has a projection that drives the timber and also a hold down, so the timber shouldn't kick back?

Devon,

Do not use that material as an insert on a saw. please!
Skybond (and AmariBond, Dibond etc) is a lightweight substrate for printing and applying vinyl graphics to, not as part of a tablesaw. That stuff can hardly hold a screw and can be ripped and folded very easily (as it is designed to do). I work with it everyday as a signmaker.

Please do not use this insert.

Thank you Green for your advice, I have had some concern how adequate the composite material was. I feared it could shatter like glass but thought the ali skin would hold it in place.


So has anyone got a piece of 3mm ali knocking around, I asked our local metal sheet supplier about a month ago for a piece and he said he was rather busy and would telephone me when he could cut a piece off.

I suppose to cut a £5 piece of ali makes it not worth his time even getting a piece out of the rack even if he had got some.

DW, you can get aluminium sheet from Ebay pretty cheap.

Example

 

[motownmartin]

Make me one John :wink:

 

[Green]

Phew! Caught you in time...

The Alloy 'skin' is very thin and can be cut through with a stanley knife whilst the plastic core is pretty plasticy and will bend rather than shatter.

I did have visions of the insert getting sucked into the saw cabinet the first time you took a cut....

Skybond/Dibond etc is very good stuff and can be made into some pretty cool stuff - just not machinery parts :wink:

Unfortunatley as a signmaker most of the materials I have to hand are pretty lightweight.

 

[devonwoody]

Thanks Slim, I will order some Monday.

 

[devonwoody]

Martin, I have ordered the 500mm x 250mm x3mm sheet which will make two inserts,
If you cover half costs I will be happy to make the second insert for you at the same time.
PM me if OK.

 

[devonwoody]

I have had another request to make an insert so if any other member wants one made please let me know before Monday.

No charge for making only request material and postage costs covered.

Do you just raise the blade up through the plate with a piece of scrap timber clamped above like normal or do you need to cut it another way as it is aluminium ?
