Von Gruff built a very nice one. Hop over to African Hunter site and read his thread in entirety, all 24 pages. You will learn a lot!!!

Thanks guys. The main thing is to make sure of exact allignment between the drive wheel, tracking wheel and platen or grinding wheel, as very nice a knife can be made on a home built as on a shop bought as it is the man doing the grinding that makes the difference

Well, I would just like to try it so I don't want to spend a whole lot of money on it if I have to junk it. But I don't want to get a piece of shmidt either because it won't work right and I won't like it. Gotta figure out something.

Mine is home built. I used Midwest Knife Supplies no-weld grinder plans and had my brother who welds for a living weld it up. Materials are inexpensive. Motor and wheels are where you end up spending some money. I'very made a couple of knives on mine.

What did you use for a motor and wheels?
25 November 2017, 18:33
Lee Baumgart
2 hp Leeson motor, purpose built drive and tracking wheels. I hollow grind blades so I started with an 8" contact wheel, discovered its limitations pretty quickly, bought a 10" wheel which I have ground a bunch of blades with and will be adding a 12" wheel in the near future.

I have watched that video by Bob Loveless a number of times and it looks like he might have been using a 14 inch wheel.

Problem with those wheels is that one 14 inch wheel costs as much as 4 new tires for my car!

What about just using a regular grinder?

I'm sure more than a few knives have been made on a hard wheel grinder, given enough time and elbow grease you can make one using a hacksaw, file, and hand drill, but the results might leave something to be desired.

Well, as I said, I am just in the "try it to see if I like it" mode so the results aren't as important as the experience doing it.

Maybe I should look for a local person who has a grinder and see if I can use it (paying for the use of course) for a few hours to see how it goes. I don't want to buy a whole bunch of stuff only to find its not for me!

I made this knife to take on a hunt to cut an elephants' tail off. (turned out I did some skinning/quartering with it too).

Just 4" angle grinder+files, torch for annealing and hardening (vegetable oil) Some silicon carbide paper and a few diamond stones. Most of this I had on hand. Bought O1 tool steel and some brass rod. Walnut I had as leftovers from a stock.

I second the thought on the nice knife. But I don't believe in shooting elephants.

You are welcome to run one of mine and see if you like the process. Mine are factory jobs but they still grind.

Your offer is very generous and I thank you for it.

However, its a bit far as I am in Minneapolis.

But thank you again! tu2

So I guess offering time on my grinder here in New Zealand is out of the question.

I've been to New Zealand. It's an offer that I wouldn't turn down. Just plan on being there long enough to soak in all of its beauty, especially down in the Dunedin area.

I am just an hour up the road from there Ray on the road to central otago which has some of the most ruggedly beautiful scenery in the country.
This is where I go goat hunting . Parts 2, 3 and 4 will be linked to this one.

Does New Zealand have a steel industry. I was just curious if the knives you make use bar steel that was made from ore mined in New Zealand.
03 December 2017, 08:58
Von Gruff
No from NZ steel. My main steel usage is from 10 series barstock with some 15N20 as well which all comes in from Australia who source it from the US although the O1 comes from England.

This lot is all done on my home built grinder

A little more leatherwork this morning

To get them ready for these knives that just need thier final sharpening before shipping. I tried a couple of different backgrounds for the pics this time. All blades are either 1075 or 1084



A longer safari knife with brass and buff horn and the field scalpel in buff horn combo in a piggyback sheath











A safari knife with walnut and brass. The walnut was from the buyers rifle stock blank to be a companion piece for a new rifle.




A new design that is a longer and wider boning knife as a EDC in consultation with NZ client so has rimu scales







The standard bing knife with blackwood scales







An left hand AH (Africa Hunting forum) EDC but without the sheath logo by request







And the last one is an AH big game hunter with blackwood and buff horn.

Those all look like good honest hard working knives.

Also looks like your not real big on high polish on knives.

Nice looking leatherwork as well.
04 December 2017, 09:49
Von Gruff
No high polish as my knives for hard work and stop at a 600grt satin finish. A high polish will show marks more than on a satin finish.It is also to do with labour input as I have a reasonably high count order book and being a one man band, and retired as well, I like to get them done in a reasonable time frame.
