Take the time to build a Gough file jig. It will help you out until you A) get a belt sander/grinder and B) get the experience in said machine to effectively create nice lines.
I haven't been making knives for That long, and I am also still using 1084.
If you don't mind a few tips:
Head out and grab a 5 gallon bucket and 4-5 gallons of canola oil for your quenchant, a digital thermometer for tempering, and a toaster oven.
When I was Just starting out, I filled my toaster oven drip tray with sand to act as a heat sink to limit the temp swings.
I also created a "Tent" with foil, an upside down "U" and a foil base for the knives to sit upright in (blade edge down, spine up). Like I said, I wanted to keep the swings to a minimum and I was able to stabilize it to bouncing between 400°-406°. With 45 mins of the 1 hour cycle would sit at 406°.
I also made my first forge from mostly scrap. An old grill with a hole cut out of the bottom just large enough to fit the drum on a deep dished brake rotor, the brake surface acted as a washer/flange on the inside of the grill. Fed through the hub was a floor flange of 1 1/2" black pipe then attached a length down to a tee w/ a blow dryer on the side and capped bottom.
Over the floor flange (inside the rotor) to act as a screen was a cast iron yard drain cover.
Once I was done, I could close it up and roll it away. Makes for an easy rolling work station that cost just the black pipe. Other items can be substituted in,
no rotor = cast iron sink
Blow dryer = old bathroom blower 110 ac plug version
Old grill = just use a cast iron grill top and cut a hole in that to fit your basin...
Plenty can be made to work for a backyard HT of 1084. If you have any questions, feel free to send me an email through the site or use the visitor message thing through my profile.
