So I managed to score one of the older cast iron delta 1/3hp models with 3 wheels. The owner put in new bearings and it came with 50 or so belts. Mostly 80 and 120 grit.

Hoping to get some time on it tomorrow. I plan to purchase some scotch bright belts along with some 40grit belts from lee valley.
 
Way to go, Alaska guy! I started out on a 1x42 myself and there is a lot you can do with them.
I would recommend doing yourself a favor and buying belts at Trugrit- better selection and prices by far for 1x42. Check 'em out:

Lee Valley is many things, but the best supplier for grinding belts is not one of them...
 
While a grinder is great, don't throw away those files. You will still have to do a lot of hand filing ..... even with a grinder.
 
Nothing wrong with using a file to make a knife.Even some of the Best Knife Makers in the world still use files.The grinder should help speed things up a little.Congrates on the score.
 
Sweet! Congrats man. I use a 1/3hp Delta 1x30. Only thing I don't like about it is that there is little clearance between the wheels and frame. If yours is similar, make sure the SB belts will clear the frame. I made a nice leather belt for mine, and while the motor is powerful enough to spin it, it won't work due to clearance.

Should be fun. I'd recommend a glass platen. I don't have one and my platen is getting pretty grooved. I'll either need to make a new one, upgrade to a different grinder or buy a glass platen.

Also, it must be a combination of the small belt size, warp speed and simply the way I use it, but I don't have any issues with the thing bogging down. Profiling kinda pretty much blows, but it's easy to grind tight radii like finger choils. I'll upgrade eventually, but I'll never toss this one. They are great for doing handle scales and I've used it for beveling leather.
 
Thanks.

Should I go with the ceramic belts from supergrit? I used the little grinder on my knife I was finishing for the wife yesterday and it was a breeze! I still use hand files to contour the handle finger grooves as its the only way I am familiar with at this point and I don't want to remove too much material. My plan is to use the grinder after I have hand filed my bevels to clean up plunge lines... I do this as a hobby currently and I don't have a need to pump out a bunch of knives and I know how to create accurate bevels with a hand file and its not really that bad.

Any advice I can get on tips to create jigs etc for scandi grinds using the grinder would be awesome. I have tried youtube, but haven't found much other than the typical "use a piece of angle iron with a screw for angle adjustment", attach the blade to it and then grind away.

Thanks fellas.
 
Oh,

Here is the finished knife... Nothing amazing, but I am learning every day. The wood on the bottom of the scales looks like an imperfection (hole in bottom), but its the grain pattern.

I think that little knife looks very good. I hope the scales are attached with more than epoxy, though...
Ceramic belts for you 1x42 won't cost that much, might as well have the best IMO. They will last a lot longer. But only use them on steel. If you clog them up with wood and micarta etc. they won't last nearly as long. Get some cheap rough al ox belts for handle material. Also get j-flex belts, they work well on wood, leather and micarta- even quite well on steel although they wear out a bit fast there. They are good for plunge cut refinement in particular. The Klingspor 312's are the best, if they have those in your size.

I think once you jump right into grinding bevels, or at least practicing on wood or mild steel first, you will discover that it's not too awful hard and will save you a lot of time. Scandi bevels can be ground freehand with a little practice, even.
 
Nice score. I recent acquired a 1x42 kalamazoo. It needs a few adjustments and mods to the platen to be able to grind bevels but it is a nice step up from files. that is a nice looking blade there as well. keep it up.
 
Those scales aren't attached with any pins.... Just epoxy. It was done on purpose because I was very curious how well they would hold up with daily use in a kitchen. My wife is going to use this knife daily in the kitchen and I wanted real feedback as to how they hold up.

Thanks for the compliments. So I have about 50+ belts that came with the grinder.

15 or so 80 grit belts
20+ 120 grit belts
20+ 150 grit belts.

I will purchase some 36 or 40 grit ceramic belts and go from there. My 1080+ steel should be on its way so I can test the grinder at stock removal and see how it does.

Thanks again for all the helpful info.
 
anyone ever heard of a Total Shop Grinder? Found one on CL in my area for $60 and Google doesn't seem to know anything about it. The disc sander alone would be a big help for me and the 1x42" belt would be better than my current setup plus it's 1/2 HP which would give me more power.

I would snag that up for $60! Would work great on handles if nothing else. At 1/2hp your metal is gonna get hot quick would be my guess.
