  1. The hard firebrick you have in your photo is fine for the interior and it will take longer for the forge to heat up as the bricks absorb heat, but when hot they hold heat very well and will radiate that heat back into the piece. It will also stay warm much longer after turning off the forge so if you come back in say 30 minutes it will still be hot and you can get back up to temperature faster. You will need to wrap the exterior of the bricks with insulating blanket, otherwise the bricks will radiate heat away from the forge and it will be much less efficient. Also the bricks will be ver
  2. OP, FWIW I brushed on ITC-100 to my ribbon burner face without issue. Just keep the holes clear, use a toothpick or q-tip to clean them out quickly after brushing.
  3. Did you ever bring this up to temp? I'm curious how hot the exterior of your casting gets and what curing process you went through? Have you experienced any significant cracking in the casting? P.s. I like your layout and build approach.
  4. What is the distance from your burner face to your floor? You should pack the sides of the burner with insulation to reduce heat travelling up the burner.
  5. OP, the claims that blown ribbon burners can run at low PSI are true. I can run my 4.25"x8.25" ribbon as low as 1.5 PSI (with my 1/4" needle valve fully open) inside a forge chamber of ~1600 cuin. before flame out. However, more typically I set my propane regulator to 5 PSI and use my 1/4" needle valve to dial in flame at higher air volumes. I have not had a need to run above 5PSI as I still have to reduce gas volume with a needle valve. This gets to forging temp in 25 minutes from cold. I have no comparison to the consumption of other designs, so I am only speaking to your first
  6. Joman, to your original issue and question, your flame out is occurring because your air volume it too high compared to your gas volume. Either: 1) decrease air flow by controlling blower speed or 2) increase gas supply via larger volume or higher pressure. As a reference I use 5 psi via 1/2" pipe for my blown ribbon burner (4.25"x8.25" burner face). If you can't increase NG pressure or volume, or refuse to switch to propane to achieve higher pressures/volumes, then you will have to decrease your blower speed (i.e. air volume), but this will in turn decrease burner performance an
  7. The interior of my monolithic forge is 18" L x 9" W x 10" H, approx. volume of 1600in3 and the appropriate sized burner was the Pine Ridge LP290 with a face of 4.25"x8.25" (perhaps a bit large but it can be dialed down). Will the interior of your 12" pipe be lined with 2" of inswool? Assuming so, that would reduce your interior diameter to 8" x 16" L, approx. volume of 800in3. Perhaps the LP190 at 4.25" x 6.25" is the proper fit? A key installation tip: Total volume is not the most critical design paramater. Instead, make sure the burner face has a minimum of 9" clearance to the fl
  8. For the archives: my first blown ribbon burner forge based on the Pine Ridge LP290 ribbon burner. Monolithic 4" arch from Kast-o-lite 30, finished with ITC-100. Automatic gas shut-off with loss of air pressure. Reaches forging temperature in 25 minutes.
  9. Arkie, no issue with access. I can get my hips all the way to the face and get as near as I like without bending over. I've worked on similar stands without it bothering my back, even on lower face heights. That's the reason for the large single leg placed at the heel, it allows getting very close. TP, the average of four 1" hardened ball bearing tests was 86%. When the anvil was directly on the ground (concrete) I was getting 90%. So at least for that test I agree I have lost 4%. Something I will just have to accept.
  10. The Mr. T. Fuller description on my original post here. (Warning: picture heavy).
  11. I wanted to share a grateful update on what I finally ended up fabricating and how it went. The final design took on somewhat of a hybrid of the 3-footed tripod and the T-stand, but I can't take credit for this design, it was a shameless rip-off from examples at the school. Previously this design was not possible as I only had access to 4" tube, so I owe an immense thank you to Haley at the ACC shop for allowing me access to some hefty scrap material. Ended up with 1" base plate, 6"/8" round tubes for legs, 8"x6"/8"x4" square tube for supports, and 1/2" plate for the feet. After ha
  12. TP: the anvil is 267#. Face height is 35-1/2". I agree with all comments on why the T-stand needs to disappear. Frosty: thank you for the wise hardy hole suggestion. Back to my original post, what angle is appropriate for the tripod legs? My thought that led me to 11/15 degrees was simply to put the feet at a position outside the main body of the anvil. Is common sense the only math necessary here? Has anyone used an angle on a tripod that didn't work?
  13. I could use some thoughts/advice/experience surrounding the suggested angle on legs placed on a 3-legged metal anvil stand. I like to get my thoughts and measurements down in a simple CAD drawing before fab so attached are a number of photos to get my point across. I am questioning the benefit of a 3-legged metal stand vs. a simple T-shaped stand (see photo). In my mind the simple T-stand is easier in the design, cutting and fabrication and offers less obstruction. Regardless of the type, the question of leg placement becomes important. I included top-down photos of each proposed sta
  14. UPDATE: While web crawling I found an online link that others may also find useful: Link removed per TOS For now he stands in the corner of the shop with headphones on and shade 5 glasses, and can't move until given permission. He gets bored in about 10 minutes then goes and finds trees to whack with a stick...he likes to sweep up metal shavings with a magnet on the end of a file at the end of the day which is quite the help. I am taking local classes that have been thus far tools and home items (e.g. profile pic). I am looking for scrap now to build an anvil stand, with the longer t
  15. Waiting to see when COVID relaxes and Balcones Forge starts having regular monthly meetings again which would be great exposure for my 5 yr old. Until then their FB and webpage have been wonderful resources so thanks for that smart tip. Go local! Duh.
