I was reading several How-tos on knife making, and it is apparent that you have to hold your stock at an angle to the face of the anvil in order to forge the bevels evenly.
This got me thinking. It must be possible to make a tool to hold the blade at the correct angle so that you can be sure you are forming your bevels evenly all along the length of the blade.
Any ideas?

I can only suggest practice makes perfect. After a couple of hours of trying you'll figure it out. Dunno about the jig, but if it's not common knowledge then it wouldn't be common practice.

You can make a jig for anything, doesn't make it easier. You are right in forging the bevels, this is a good time where Newton's law comes into effect, for every action there is an equal and opposite reaction. WHen forging the bevels on one side, the anvil is returning your blow's force(why anvils witha good rebound are the best) from the other side. You can form both bevels on both sides simultaneously, it's a very cool effect, a minute to learn a lifetime to master.

Does it make it harder to screw up, though? ;D
That anvil of mine bounces the hammer back nicely. And makes a nice clear ring. It'll make me deaf before long, I reckon.

EAR PROTECTION IS A MUST. Also, to help with the ring wrap a chain around the waste, stick some magnets to the horn and/or heel, or set the base in sand.

I think I'll do all of that (Pimp my anvil RIGHT up). I'm pretty deaf already, so a little more would be terrible.

I wear ear plugs, then muffs over those, and motocross goggles with the straps tight over the muffs to ensure a snug closure, and I still keep goin' "What" to everyone. Obviously a respirator is part of the package.

You can hang a bucket off the bick from a leather strap and then add or remove sand until you get the best sound dampening. Once done, mark the inside of the bucket and then dump out the sand. fill the bucket to the mark with concrete, add a steel eye in the center and let the concrete set. recover your bucket and use the hang weight to dampen the ring, you can hang it off the bick or tail as needed to get it out of the way.

That's a plan. Anything to avoid further deafness!!
Hey Bren, have you developed any breathing trouble from all that grinding you get through? I spend the morning grinding rust off that forge and I am clogged right up. All I have are crappy little surgical masks.

I make so much terrible dust (inches deep almost), I don't go near my work bench without my respirator. Your local department store (we have one called Big W owned by Woolworths) should stock them. Get the ones with the respiration valve if at all possible, it stops it venting up around your nose and fogging your goggles. Also motocross goggles are fully enclosed with foam, so the dust can't get in your eyes like with glasses. The respirator looks like this: They're about $4 a piece, and will last a few uses. Whatever you do don't bother with the flimsy 5 for $1 types. They don't seal properly. Look for the standards approval tick. Before I started using these I was blowing steel coloured snot out and coughing it up. Never since I got this solution. Safe grinding. And yeah, squishy ear plugs used under muffs will help. No solutions for the neighbors yet. I live on 50 acres so not a problem.

Lol; He's so Metal he COUGHS steel! ;D Thanks Bren. I think I shall have to get some of those before I carry on. I have full-on compost coming out my nose after breating all that rust in. I still have the legs, hearth and water tank to derust. I'm going to be SOOOO fed up of grinders by the time I've finished. Both of my grinders give a horrid vibration no matter what you do, so my arms are completely numb.

Just wire brush them, or use a wire wheel on the angle grinder, will do a better job and be easier and quicker, MUCH quicker.

I've been using a wire-wheel on an angle grinder, and a grinding wheel on another angle grinder for removing the (very solid) welds.
It still took all day. It is very rusty.

Moto cross gloves incidentally help dampen a lot of that vibration. I always wear then when whipper snipping (line trimmer) or using the angle grinder etc.

Matt, Pick up a can of "Naval Jelly" at your local bits and bobs store, it will really speed up the process.
