Nathan the Machinist Grinding gadgetry

Should probably get a new more powerful pump and run longer hoses or perhaps put a lid on the Homer bucket I am using.

I use a lid on mine and it works great at keeping crud out of it. Had to modify the bucket & lid for the hoses, but it's pretty well sealed and I haven't had to open that bucket once in the last year and a half or so. The water is still clear!
 
I freeze blocks of ice in big old coffee cans and drop that in my bucket when I start grinding. If you're not using ice you're missing the joy of a frosty cold platen. You don't need to lift as frequently.

As this is adding water to the bucket you have to pull out that much water when you pull the can out and dump it. For me the regular influx of fresh water has kept the funk from hitting critical mass.
 
Nathan, mine clogged after a lot of HEAVY grinding before the Belgian show. I had a number of ledge damascus pieces and some gunky handle material, etc. I though the little fountain pump had gone bad, so I go another one. Sludge was the culprit.:D

Pat--- Oh, you're getting a gosh damn picture!!! :mad:

:p ;) I was thinking about it over my cup-O coffee... and maybe my work rest/table is worth writing home about, :p because it works and it was stupid simple to make work. ;) LMFAO! As you well know, I'm very good at over-thinking things... I didn't do that with the disc table. It shows :foot: But the function is there.

So where's the pic? Did I miss it? And, if a fella only got one disc would you recommend flat or 1º taper?
 
Patrice,

I can send you pictures of the RW Wilson disc sander stand. I just don't have a photobucket account anymore.
 
Thanks Brian, I got your pics from Fb. I really appreciate. Got to build me one of those for sure. :thumbup:
 
Haven't seen this mentioned. Bleach. A little does wonders to stop things growing if you aren't changing the water.
 
Pat (or anyone else interested) here are some pics of the work-rest and its mount on my 9" disc sander.

I was dreaming up all these fancy ideas to fabricate a work-rest, and also had my eye on the super cool set-up that Rob at Beaumont offers... but then I remembered I had a work-rest from an old Craftsman belt/disc combo machine tucked away in a drawer.

What I came up with was very quick and dirty, but it works so well that I have no concern about changing it. Especially since I don't use a work-rest on the disc very often.



It goes on and off in seconds, and is really quick to adjust.

The Craftsman's work-rest base has a 3/4" rod with a flat milled on one side. It just slid into a receiver on the sander, so I just ran with that.

I started with a stubby piece of 1-1/2" square bar. I drilled and tapped a hole for a 3/8-16 bolt in the side of it, then welded a piece of plate to the end of it.

I put the square bar in the lathe with a 4-jaw chuck, and faced the plate (to make sure it was squared off to the bar), then drilled and bored a 0.753 hole through the plate and the square bar for the 3/4" rod to slide into.

Put some bolt holes in the plate and the disc's motor mount, and it was ready to work. Easy peasy.

I threw together a new surface piece for the table, because the factory one has ridges in it. A piece of ss or aluminum would look nicer, but I didn't have any and it wouldn't make it work any better.
 
Great idea, Nick. I'm hoping to add one of Nathan's discs to my shop in the future, so I'm saving your post for future reference. Thank you for sharing! :thumbup:
 
I've been making knives for only a short time compared to many of you but it still always amazes me that every time you start to think that you have learned all there is about a subject someone else comes along and blows your mind. that attachment for the grind is only one example of many.
 
I will jump in here for some education about pumps. One of the most important things here is the amount of head pressure the pump and overcome. If the pump is only going to push water 2 feet above it then a smaller pump would work. However I would agree with Nick that you want something around 5 feet of "head lift". That way you can move the pump around and have it at different levels ands till get what you need.

The layout of your shop and how you are going to hook it up will determine which pump you need to purchase. If you have your grinder on a stand that sits 7 feet in the air and then you sit on a really tall stool then you need to think about a more powerful pump. But most guys are not giants and the previous statement was as super exaggeration.
 
The easiest solution?

There's a house for sale down the road from me, and it has a shop.

If you moved here, you could easily shop on ebay, HF, and all the other U.S. suppliers without worry of $5,000 shipping charges on a $10 item.

And we could hang out and stuff...!!! ;) :D
 
I think that HF does sell to Canada

Princess auto has several pumps, but of course the prices are much higher

Not sure it's the easiest Nick but sure would be the most fun. :D:D:D

Thanks guys for the pump model and the “head lift” info. :thumbup:

Update:
I did find these Hydrofarm Submersible Pumps. Not sure about how much head lift it has but can I go by the rated GPH instead? There is this one rated for 880GPH...
