I need help. My uncle needs some kind of machine to slam down on knife handles to break them apart. Do you know where I can get something to do this, or hire someone to create a custom tip?
Timothy here (the fella doing the striking in the video). You will find that a 14K gold fill blank will exhibit lots of cracking on the edges and crazing in the surface texture.
Thank you so much Timothy! I'm so intrigued by all of the workings of how to make something like this, it's absolutely beautiful! You guys do amazing work! Thank you for taking the time to answer my questions.
I use a similar tool-dip material to protect my wood-cutting profile blades. I use a magnet to hold onto the steel I am dipping to avoid burning my fingers.
This was really neat! I had no idea you had a youtube channel! This answered my question as to why my set of Franklin Mintmark punches are different lengths. They were made by a professional company but my engraver said he made modifications to the punches. Score marks one side were obvuously to tell the engraver that the punch was correctly placed as long as he could feel them on the backside with is thumb and the number or lack of score marks told him what size the Mintmark was. But I could never figure out why they were all different lengths. Your vid answered that! I loved the hardening process! It seemed I was the only guy in the inspection department who knew how to grind and air chisel tip to suit our needs better without them breaking for everybody else! Apparently they had no idea of what the bucket of water was for! All I need now is to see how to harden a die. Most of my dies are hardened already but some are not nor are my die blanks of course and I have no idea of how to harden these dies without having to sent them to John Sol over at Columbia Machine. John is so busy that I hate to send him anything. So I'd love to see how you harden your dies. For the record my dies are A2 and D2 Columbia style and I like the at R58. Ken Potter
So what happened to the round die holders that were removed from the bottom of the ram???? they should have gone with the press. Those were not in the parts that got loaded??????
Many years ago when i did my own heat treating, I used the stainless wrap but wrapped the die in paper and set in on a charcoal block in the furnace. It also cut down on the decarb. They say over certain temps, there is no oxygen but you have to use the temps prescribed by the metal manufacturer. They all have heat ranges for different hardness and toughness in tempering.
Such a great method. I can imagine you can't use just any old paper due to off gassing, but I really like this! It is amazing just how much a few degrees either way cause such a difference between different manufacturers of steel. What we do is extremely tolerant of the variance so we can get away with a pretty big window here at Landis Studios. I use the same recipe regardless of manufacturers and don't run into trouble. I'm never maxing out the intended use so as long as my temper is thorough I don't have any trouble.
When I remove the safety guards from a Denison Multipress - "Meh, I got time". When I remove the safety guards from a direct drive mechanical press - " NOPE."
Rookie question here but, what is the actual name of the piece that holds the die? Recently acquired a Obi press but came with no tooling. Thanks very much! Really helpful video, too!
One last question if you don’t mind? Could you by chance tell me the manufacturer of the die shoe you have? Doing a bit of searching online and I’ve yet to see one like yours that holds the round dies. I see plenty of round dies on eBay but nothing to hold them. Thanks again! Really appreciate your time.
Great intro any chance on another video talking about the other aspects of the press? Including the slip / safety clutch, adjustment of the brake, etc. Just started restoring a tiny 6 ton obi. Seems all videos about obi presses are just short demos from machinery suppliers and almost no talk about the machines and the dies themselves .. thanks!
Boy I'd like to...I just rarely find the time outside of regular production. You are welcome to email us though and I am happy to help with what I can.
The most amazing and best playing/sounding banjo picks I have ever used in over 50 years. Their quality will remain long after the price is forgotten. Worth every cent IMO.
You ever figure out how those plastics coins were made? Ive also tried researching them but the only thing ive discovered were they they made of bakelite so you right when you said its phenol, you can confirm by rubbing the coin with your finger making alot of friction then smelling it, you should get a somewhat strong whiff of a formaldehyde
The discs are just simple cutoffs, in terms of how they are made. I don't know if I mistakenly referred to them as coins, but they are just bushings for the table to slide in the chamber. If those weren't there I would use some kind of hard plastic...there are SO MANY varieties available these days, including some impregnated with lubricant, which would be exceptional in this application.
@@landisstudios5781 ahh i see, then i wrongfully assumed it was a plastic/fibre coin, i mentioned it because i know of official coins minted out of a fibrous bakelite - mostly tokens but there are also a few pattern pieces that was made in South Africa by the mint that was meant to distributed to schools for educational purposes but never did, this was back in the 30's but yeah anytime you run out of blanks, that stuff could suffice, captures sufficient detail
@@rdesousa8955 Ah! I see. Yes, I have seen some governmental stuff from around the world made from similar material. Tax tokens and the like. Nothing meant for wide circulation, but it is cool how well it performs as a material!
Just wondered if you had considered making a clawhammer index finger or middle finger pick for clawhammer players? Some players use index some use middle.
We have had a couple people order modified picks to experiment with this...we have not gotten any feedback yet on their success, as it was their idea and not ours. While there are no immediate plans, we would certainly welcome input on the needs of the player.
@@fuhk we keep pretty busy doin our own thing, so we aren't taking any custom work on right now. However if you want to send an email with some details we can at least look.
