April 15, 20215 yr So, I’m hand sanding a blade for the first time. So far so good, but the area around the plunge grind is giving me fits as far as making all the lines even. Any advice on how to finish out sanding around this area? Thanks in advance.
April 15, 20215 yr I've never tried to mirror polish a blade before but I've sanded a lot of other things and to get into weird corners etc I use blocks with sandpaper attached. If I can't get into the corner with a block I use pin files. Pnut
April 15, 20215 yr One trick I just picked up for sanding into tight corners is to use abrasive nail files, available for cheap from your local beauty supply store. These go up to about 600 grit, if memory serves.
April 15, 20215 yr There isn't an "Easy" way that I know of. Wrap the abrasive paper around something with a sharp corner, drag it down the face of the plunge, and then straight out towards the tip of the blade is one smooth movement. Resist the urge to rub "up and down" the plunge line from spine to belly because it makes even more scratches to get out. Plastic door shims make for a nice thing to wrap the paper around. Sometimes I loose patience, and jamb the paper into the corner with a push stroke from further out on the blade. This works pretty well too, but makes J swirls that you have to sand out later. Because you are using such a small area of the paper, you have to keep moving to a fresh section every few strokes. I find it helps to sand that area first. Once you get it to where you like it for a particular grit, sand the rest of the blade to the same grit level.
April 15, 20215 yr Riffler files are your best friend, and dont forget to make a safe edge where necessary on your files

I've been using both for small stuff for years but never thought they'd be rigid enough for removing much metal. I use emery boards frequently to clean oxidation from the electric ignition for the dryers at work. They work great for that. I never really considered using them to remove metal because of how flimsy they are.
April 16, 20215 yr The disposable emery boards. They are flexible and I wouldn't recommend them for large areas, but still good for smaller bits that are hard to reach in other ways. Fine sandpaper glued to tongue depressors also works.
April 16, 20215 yr Ignition files work great, made of metal. May take some time to find them now days.
April 16, 20215 yr When I get to that point, I use my buffing wheel with red rouge. Just have to be careful and not let the blade grab the buff.

April 17, 20215 yr You may have heard the term adjusting or replacing the *points, plugs, and condenser* during a tune up. Ignition files were used to file the ignition breaker points, when cars used breaker points in the ignition system. Look around and see who has a smile on their face. Ask them what BTDC and dwell means. Sigh, the stuff your exposed to on a blacksmithing site.
April 17, 20215 yr Before Top Dead Center (ignition timing) and the length of time the points are closed to charge the condenser & ignition coil.
April 17, 20215 yr I haven't had a vehicle with points since the early nineties. I think the last one I owned was a 84 El Camino. It's good to jog the memory now and again. My memory has been giving me some trouble the last few days. I've been forgetting or confusing one thing for another pretty often lately. Hmm. Pnut
April 17, 20215 yr Just had to dress the points on an old tiller last week. The last car I had to do that with was a '72 Spitfire, but I was still driving that car until 6 years ago.
April 20, 20215 yr I have an old Willy's too, a 1953 M38A1 Overland, they are hard to kill. https://www.iforgeiron.com/topic/52610-jeep-willys-lovers/
