  1. Thanks Alan! I will be playing with hamons... but I gotta walk before I run- so that will have to wait a bit. Thanks Joshua- I have been dickering about here and in a few other forums for a looong time unfortunately- too long. I keep hoarding drops and scraps from machine shops of known steels so I can dial in a process and figure it out... thus the motley variety of my stash- I even have 2 plates of ATS-34 hiding about (from a going out of business machine shop- yes I am aware I need foil and a HT oven for that- just couldnt pass it up for the price)... Think I am going to have a fun winter- AAA sounds like the bees knees for startup! Thank you folks!
  2. So I am still a beginner after a few years thanks to just not being able to put the time "IN" I need/want to- I have the ability now to spend a bit more time and dedicate some financial resources to this. Annnnnd- quenchants have me truly stumped! I have a stash of 1075, 1080, 1084, 1095, O-1 and 52100 and 4140 bits I want to get through and I need to know is PARKS 50 too fast? or should I be leaning to "AAA" Confused and hoping for a bit of guidance- thanks!
  3. Thanks Simon- Im in the process of fabri-cobbling a setup right now... I like the water/bucket idea- I'll be using a rectangular "tote" bin- One fellows shop near me who does a LOT of plasma cutting has a similar setup with a "tote bin" style water trap. The big thing for him is deflection/cooling of the particles- he added a stainless steel mesh screen like you find on range hoods and over house stoves into the water. He lost a few feet of CFM and a bit of static pressure- but he hasnt burned out his shop collection system since adding it. Im working with a couple of ideas about the inline arrestor- Dan, (the fellow who wrote the blog post) was kind enough to chat a few emails worth of info- after a year of use the head of the vanes and the central fixtures are not abraded or significantly worn down. I think one of the success factors to his solution lies in the fact that the surfaces of the vanes are NOT smooth- it "forces" turbulence into the airstream, causing the particles to bounce around more (plus the lower pressure combined with the centrifugal action of the vanes) contribute to a longer air-path for the spark to travel and expend its energy. For ambient dust collection- I think there is a solid calling for a fan-tower. Ron Calverly on YT has a good build and I already have the blowers - I know its a tall setup- but Im looking at putting a timer switch on it to run after I leave for the night to keep filtration going... I have some sensitive pieces I cant get dirty out in the shop (Some of them being the wife's tools) and an Optical Comparator to keep clean. They already have dust covers- but looking for more substantial long term solutions. Ill keep you posted- build should start after I get the tablesaw cart built to get the wife's tools some much needed storage! Below is the vid for the cabinet.
  4. Understood- Going to be building it anyway- just would have liked to get a few thoughts from the collective. I just have to keep the shop a bit cleaner than some as it is also a shared space for the wife and my jewelry work (And Ive got a 6 year old I would like to have playing about as well)
  5. I have looked back at a lot of folks posting about dust collection- Ive read the threads going back to pre-2015... Im looking to build a system for my small shop- and wanted to get some opinions/input before I jumped in from those who have gone before me (you guys)... As there is nothing really solid recently in the forums I figured I would ask for some input. I will be putting this system on a surface grinder as well as my 2x72 using blast gates or a "Y" switch at the input. My decidedly LOW TECH method of controlling ambient dust has been working very well so far but I have a LOT of residual dust landing on everything (neodymium magnets in sandwich baggies hung around the rafters- they get fuzzy QUICK. Easy to clean though- just turn the baggie inside out, remove the magnet, dump the bag then put magnet back in the bag and re-hang) Watched Neils series and loved it- and recently came across Dan Comeau's spark arrestor idea here: DC KNIVES SPARK ARRESTOR This solution mechanically mimics industrial solutions for the same issue, and would appear to be very do-able for my level of abilities. So I wanted to get feedback on using a Fan Blowing across me towards the dust inlet, a Water trap at the grinder inlet, then a Spark Arrestor in-line, and a modified Dust Deputy/ canister filter setup on the end... really trying to aim for cooling the sparks before the canister. I found a setup similar to what I would like to construct- it has a Dust Deputy mounted to a modified Chinese-Freight dust collector. The user modified the system and added a larger diameter impeller (In this blog he purchased a Rikon impeller). The larger impeller upped his CFM and static pressure. The video of the system is at the bottom of the page, and below that is a "blow by blow" tutorial- Here is the link to the blog-post: GRAYHOUSE STUDIO HF DUST COLLECTOR MOD So- My questions are: 1- Is this overkill? I do not think so as I already use partial face masks and 3M cartridge filters- but need to get the dust under control if I gear up or hope to keep anything clean! 2- One way to "boost" the system efficiency is to have a fan blowing on me towards the dust collection port as well- Does this sound crazy? (In lab situations and vapor spaces I have been exposed to the workers are in-line with the airflow to keep a positive pressure vent circuit in place.) Any thoughts are appreciated- Ive been gone far too long from this fellowship. Be safe and well!
  6. I already joined ABANA and my local guild- one of the first things I did was try to source info locally- and everyone I have encountered there so far are good eggs- My job keeps me dynamic with shift changes (rotating nights/days odd weeks and such) so I cannot attend often- but still enjoy the group!
  7. Mr Boggs- Thanks for posting the thread- Im trying to learn to "see" and this is very insightful. (pardon the pun) as usual you have helped me add another tool to the list of "stuff to make/learn" I dont really post all too often- as I am still learning the ropes- but I appreciate the time as a student- to see good tooling. Im trying to learn good practices and having clean examples to work to are always awesome. Thanks
  8. Neils- Very cool build- I have watched this on your channel from the start- Bravo! For your build consideration- putting several Neodymium Magnets of a fairly strong nature inside a Kydex shell free hanging in the HVLP airflow stream portion will collect some dust- but the particulate you may be trying to collect may be the ceramic/mineral abrasive component of the belt (non magnetic). For that- water-trapping is still the king unless you are venting to the outside (even then it may be warranted). I know in my old shop we had "dust baggies" suspended from the joists and we noticed a serious decrease in ambient dust (strong magnets in ziploc bags. It fuzzed the wi-fi signal and the cell signals a bit- but that meant more work less surfing- so it worked out.) I enjoy your videos and respect your time spent sharing these adventures- as before- Bravo and awesome as usual! KD
  9. Cleaning out- these have to go- Free to a good home! I've switched my bench molding over to petrobond- and just don't cast as much Greensand anymore. Bring buckets/bags and boxes- these bags are crispy old. I work odd hours- so be patient- I will usually get back to you within a day.
  10. Friday I helped an older gent clean out his shop and get things on pallets for moving- The city has claimed his barn area for eminent domain to widen a road. If anyone is nearby the Hampton Roads area and needs an anvil- he has 2 in great shape! The Kohlsawa: The Peter Wright: And a gnarly doorstop Vulcan Arm and Hammer: And I scored a big find for me- a 300 pound Fisher 1942: He also has several Swage blocks and stands (Here is just one) I had a blast rummaging and cleaning- Im heading back next week to help him tackle another section- so hopefully more posts then!
  11. Took my intro to blacksmithing course at my local guild this weekend- had a blast... On my way to the entry test next month- now to forge out the remaining pieces (5 of each) for the "Noob merit badge" to get some street cred in the guild. Heating the blanks- making the scrolls, learning the ropes... Making the hooks- yes the spikes are TOO BIG... but they will do well cinched! And the wife loves her keychain leaf... Its a start!
  12. Bravo Chris- Did you stabilize the wood yourself or get it done? I think your horizontal carry choice should be a great canvas for that sheath!
  13. Hard to believe no one has taken one of these to the XRF scanner- just a simple interwebs search shows this steel has been around since before 2012- Oct 2012 Fine Woodworking PM-V11 article If they are using a boutique manufacturer (low run counts strict quality/lot/proprietary sales) then they have a great secret... Sounds like a bit of smoke/mirror ahem... ummm "Marketing" materials. But- then again- maybe they are just really into developing cutting edge tools (couldnt resist- pardon the pun!)...
  14. Bravo Ms. Jennifer! I appreciate your camera angles- you can see where the metal moves- Thank you for posting this- I will be visiting the other videos this week as well! Kerri
  15. John- I like it- You need to look up "Chopped Carbon Fiber"... The OSB has a similar "look" to its multi direction layers. Like the other folks mentioned- dye it and see what happens! Who knows- maybe a Chopped carbon sleeve? Bravo on experimenting!
