How To Grinding bevels and how many knives will it take?

I feel it would improve your posts if less periods are used.


I don't think anyone's been nice enough to point that out so hopefully you don't get offended.

I don t understand what are you saying .Can you do it in simple English so I can understand ? What you mean with that many/less periods ?
What would improve my post if less periods /of what ??/ are used ?

I started with a jig flat grinding for a couple blades. Then I did a couple with a jig hollow ground on my 12" wheel for a few. Then I went to freehand on my 8" wheel with workrest and now I do everything completely freehand bellied up on my 12" wheel. Starting with a jig completely sped up my learning curve. Really help me to get a feel for it. Of course you get out if it what you put into it and like I always say there is no substitute for getting just doing it. A couple more weeks and I'll have been making knives for a full year. Practice, practice, practice. There are no shortcuts! Here is my most recent blade:

Considering English isn't his primary language, maybe you should repost this in grammatically correct Macedonian.

He posts often enough for us to help when we can. I'd hope someone would help us out on the Macedonian Blade Forum if we posted there for 6 years and made it our home.

This is Natleks home, he is here to stay, so we should be kind enough to help.


N Natlek Yes, much better 👍

Hopefully so. I find a lot of value in his posts.
 
One rule of thumb in making knife blades, the fewer attempts it takes to achieve the goal the better the outcome. Develop a process that is as simple as possible and you will produce better results. It's why jigs work. The same results are produced every time the process is done using a jig. Not just in grinding bevels but in all aspects of shop work. The more jigs incorporated, the easier the work. Ask a machinist.
You are not in competition with other makers, you're competing with yourself. Do what works for you in your shop. Work smart.
Good advise from others posted here, Fred
 
One thing that really helped me was the Bubble Jig from Fred above. I was kinda all over the place (especially with my left hand) and got one of his jigs and improved dramatically. From that I can now do much better just freehand but I usually still start with the jig to get a starting point and work from there.

I do the same as you. After the bevels are "set" at the desired angle, I remove the clamp and don't use the BJ. Once you have accurate bevels set the grinding is easy.
If you're making hidden tang knives it's a good idea to grind the tang at the same time. Just reset the BJ with no angle and use that setting to grind the tang flat. Doing this makes the tang match the center line of the blade so when you go to fit the handle it all fits up nicely.
Thanks for your post, Fred

I've made 125 knives this year and I'm still not sure I know how to grind. May want to check out this video for a little different take on bevel grinding.

Hello! I just recently got into knife making as a somewhat serious hobby after my day job. I have invested some amount of money in it (not crazy though) and have been trying my absolute hardest to complete at least 1 blade.
I recently have upgraded from a tiny 1 x 30 belt grinder to a 2 by 48 grinder from jet (The Jet IBGB-248, please let me know if that is an alright grinder for knife making. I am not making anything very large, so the work rest is enough for me for now).
My main question is, granted I have a 9-5 job and I am brand new to this (So far I have ruined bevels on 6 blades) what would be the best approach to grinding actual bevels. I have watched a decent amount of videos on YouTube about it and I am not sure if that is helping. I am aware this is a trial and error process but just through how many knives did you guys and should I expect to go through before I will successfully bevel one?

Also forgive me if this question somehow violates some posting rules, literally just registered an account so hopefully I am posting this at the correct board

Start grinding the blades after they are hard. It's much easier to have better control. Soft blade need a soft touch and the belts tend to grab. So long as you are not grinding any crazy steel ceramic belts cut low carbide steels with very little effort. Yes you will need more pressure and you will need to be careful not to burn the edge but you would still have that problem anyway. Get a sheet metal gauge and once you get to maybe .030ish put on a new belt and bring the edge where you want. Since you probably can't adjust your speed only go till 120 and then hand sand. 120 and a ScotchBrite isn't horrible if you just want to stop and enjoy your knife. 220 is better and with practice you can get there. You can out a piece of leather on your platen with spray on glue and blend your grind. I think a lot depends on how you learn. Some people take it slow and others just burn material. Time budget and you all matter. Just remember to use new belts for when you are trying to have a soft touch and then lightly used for taking off the bulk.
 
I’ve probably made 40ish knives by now and have been confident in grinding the last 10 or so. I find it really really helps to grind four or five at one time. Helps you stay in rhythm, feel more confident, and let each blade rest a little while grinding the other ones. I grind post heat treat.

I also have been making mostly kitchen knives the last few months. They seem to be much more difficult to get nice grinds on. But about one month ago I decided to finish grinding all of the little edc and hunting knives I have heat treated. It is 12 total. They were a lot easier to grind than the last few I made. Much shorter tip to spine and tip to heel, so they were easier to keep the grinds consistent and look nice.
