Dust-Proof Housing Felt Seal

[Trevanion]

I recently bought a pedestal grinder from around the late 1930s which has these “Dust-Proof” housings in front of the bearings which house what seems to be a felt seal which contacts the on the flanges that the grinding wheels sit on to keep the grinding dust out. One seal was OK but the other was mostly gone and completely soaked with grease, so might as well replace both while I’m at it.

You can get sheets of felt “oil seal” which are quite expensive, seeing as I only need a couple of small strips about 6mm thick and 8mm wide. Does anyone know of a good place to get this felt stuff from? Or whether there’s a better alternative that’s been developed in the last 90 years?

I seem to recall getting some free samples when I wanted to replace the way felts on my lathe.

Felt still the best thing to keep abrasive crap out of moving surfaces. Do usually tend to need a hint of lube.

You can get A4 packs of coloured felt from B&M too, I believe. In the stationery section.

I have some 1/4" (McMaster Carr F1 grade. I made all new wipers for my lathe from it.)
You'd be welcome to a couple of strips.
PM me the sizes & your address and I'll put them in the post to you.

McMaster-Carr is the complete source for your plant with over 595,000 products. 98% of products ordered ship from stock and deliver same or next day.

They are in USA.

HOWEVER, when I tried they would not ship overseas. I did not establish whether this was a general policy or whether it was just for felt.
Through the kindness of a Practical Machinist forum member I was able to buy some and have it delivered to him. He then shipped it to me.
Because of the difficulty I got several thicknesses.

General policy I hear, I think they have been stung before so now just say "no".

You won't mind popping back then, being as it only just a stones' throw back up the road from you, collect some felt strip for Trevanions' dust seals and then pop it in the post to good old Blighty......

Good lad.....

I posted a couple of strips yesterday. I did think at the time posting wool to Wales was akin to 'coals to Newcastle'.

The sheep are mostly for decoration these days!

AMS do the felt rings for the EQ spindle moulder, this looks a similar size. Probably cost a gazillion pounds though.

 

[Screwdriver]

Out of interest, if you're buying felt sheets, how do you intend to cut out the rings?

Naw....you swim upstream to the source.
You start by feeding the sheep donuts.....

Well, I presume that these were done as a strip and then just inserted with each end butting up against each other, rather than trying to cut a perfectly sized ring and fitting it within the housing. There may be a risk of dust migration along the seam, but I would think it is minimal.

The lathe tailstock quill has a felt ring seal.
One of my mates laser cut it for me, but the cut surface needs a bit of a rub to clear the burnt debris.
