    I bought a Silverline 115mm 650W angle grinder (Ebay UK item number 222240763618) and a Dust Extractor Hood (Ebay item 115698104841). The hood prevents the angle grinder from rotating. I need a rubber spacer under the locking collar to push the grinder blade up, the angle grinder is an M14 thread. Please let me know if this is sold? Thanks,

    Ebay 115698104841 don't exsist, you got link to item.

    Should never need or fit any washer/spacer under grinder disc, what disc you using, I had problems with some of the thin cut blades snagging on my Makita grinder.

    Post a few photo's,will make things clearer.

    What disc's using

    That guard locking collar looks a standard size, so should fit your grinder collar,something isn't align correctly, or it's the guard itself, or the disc's your using.

    Got a Bosch metal guard as below, & it fits both my Makita & Bosch grinders.

    The Herzo dust extraction hood at this weblink: https://www.amazon.co.uk/dp/B01G501XTK/ref=cm_sw_r_other_apa_i_IaMGDbZRZ1K5R, is basically the same as the dust extractor hood I bought (https://www.ebay.co.uk/itm/Dust-Ext...087322?hash=item3d8425fd9a:g:PJEAAOSw8mtccLuU) with the black rubber spacer (shown in the Herzo weblink JPEG to the right of the grinding disk). I need this specific black rubber spacer and the supplier of my dust extractor confirmed this. This Spacer pushes the grinding disk upward to stop the disk from hitting the inner plastic face of my Hood. Please let me know where I can buy this spacer? The download link for this spacer is: https://my.pcloud.com/publink/show?code=XZ8WCHkZALMnitkbBcyIk73Tni2cuuBdEeoy

    Poor design hood then, if washer is needed then it should have been included, if not your supplier should sort the problem by supplying washer or full refund.

    The supplier is in China, English isn't their 1st language. I've opened an Ebay Resolution case and the supplier doesn't know where to buy the washer/spacer from. Any chance you know where to buy the spacer from?

    Better to get a refund I think.

    Why can't you make one? If you know the size buy big washer or a few but easy to make one out of plastic or ply. I did read reviews on this and some modifications were needed with some grinders

    The washer is 2-5mm thick, M14 thread,I could make one out of a rubber block. Where can I get rubber washers from?

    Why rubber? Why not metal?

    An M14 Form A washer (CTL6451214L at Cromwells) has an outside diameter of 28mm and thickness of 2.5mm.

    A Form G washer would have an outside diameter of 42mm and thickness of 3mm.

    Unfortunately most online sellers only do packs.

    It isn’t in the Cromwell catalogue but they be able to order you one if you go to a branch.

    I tried the M14 A2 Stainless Washer (https://www.spaldingfasteners.co.uk/m14-metric-a2-stainless-steel-flat-penny-repair-washers/) and I realized that the locking collar under the disk is threaded and has 2 flat edges. A standard M14 washer won't fit under the disk. You would need a much larger diameter washer because of the locking collar's flat edges, probably a M18-M20. Because of this I wasn't able to fit the grinding disk onto the washer. I also called Silverline Tools UK ( 01935382222) about their 650W DIY Angle Grinder (https://www.silverlinetools.com/en-GB/Product/ProductDetail?ModelName=571295) and they don't sell dust extraction hoods for this angle grinder. Not sure what to do now. I have cable tied a flexible onto the angle grinder near the blade which is hoover-attached and this helps a bit.

    Have you looked at using discs with a depressed centre to give the required offset?

    No the disk I am using at the moment is a flat 115mm Silverline angle grinder cutting disk (https://www.amazon.co.uk/Silverline-447131-Metal-Cutting-Discs/dp/B000LFXWNG). The disk with the depressed center (e.g. Toolstation 115mm angle grinding cutting disk https://www.toolstation.com/dpc-met...MI1aPg_PD95AIVD8DeCh22NQcLEAkYAiABEgJiAPD_BwE) should ensure that the depressed bit of the disk sits in free space and allows the rest of the disk to sit above the dust hood. Have you tried this arrangement?
