Zeb Camper 780 Posted July 18, 2019 Share Posted July 18, 2019 Tree stuff! 2 handrails, they dont have the cap rails and labs tongues on yet, but I'll throw those on later today. They will bolt onto the side of a house and down a set of steps. The viney bits will get leaves tacked onto the ends to finish them off. I wanted to do a cooler design, but as always, the boss said it'd cost too much. 3 Link to post Share on other sites
Bruno 89 Posted July 19, 2019 Share Posted July 19, 2019 (edited) Had a problem with my power hammer. So I decided to repair/upgrade. They way I had the connecting rod to spring linkage was dependent on the Rubber's inside the leaf spring to maintain stiffness. Well guess what ? The desert dried out the rubber. So as a result, the connecting rod linkage was causing a slapping effect. The rod would either move the linkage forward or backward during use. Wasn't any fun. So I fixed it. I added a Linkage stabilizer I guess you could call it to stiffen the spring linkage, and upgraded the connection to the turn buckle/height adjustment. The turn buckle was connected using a 3/4" grade 8 bolt, but it was starting to wear down, so I changed it to a 1.5" shaft with grease fittings. Seems to be running smooth now. Now I just need to shorten the connecting rod by a few inches so I can get full height again. Not running it at full speed. Seems like I can get 3-4 hits a second.

Troels Saabye 41 Posted July 19, 2019 Share Posted July 19, 2019 Unboxed my new chainsaw-backpack from TrueNorth ^^ lots of room for tools,water,fuel and other miscellaneous items Link to post Share on other sites
Brian Dougherty 1,167 Posted July 19, 2019 Share Posted July 19, 2019 Wait! A chainsaw pack? I thought you Scandinavians still used axes for everything! Seriously though, it looks like a nice pack although it also implies a lot of hard work coming your way! Link to post Share on other sites
Troels Saabye 41 Posted July 19, 2019 Share Posted July 19, 2019 (edited) We evolved Brian ! Though the pack does have a designated axe pouch Indeed hard work incomming -> got 2 acres of densely wooded land in need of clearing ^^ Nice and secluded, just the way I like my work Edited July 19, 2019 by Troels Saabye Link to post Share on other sites

I learned long ago to never buy a cheap chainsaw. I have 3 cheap chainsaws. Two of them work. Had them for years. One turns over real nice but won't run. I'm installing the rebuilt regulators on my oxy-acetylene rig. $65 and they look brand new. Link to post Share on other sites

I don't have a preference, I've only used Stihl, and some no name junk - managed to break 4 of those before my father realized quality over quantity so he bought a Stihl, a smaller one 362, going to buy the 880 soon we have too many 32-42" trees Link to post Share on other sites

Bruno 89 Posted July 20, 2019 Share Posted July 20, 2019 (edited) Well, my power hammer repairs worked beautifully for about 3 heats. Then the Linkage stabilizer snapped off. Guess it wasn't thick enough. I got some sucker rod which should be plenty tough, or some 3/4" square stock. That might work better. Since I had the forge on, I pounded these two out of some leaf spring. Going for a "cai dao" , or chinese chefs knife. So they will be on the thinner side. It's nice sometimes to just use the hammer and anvil. Good reminder of why we don't need bigger tools, but like them anyway. The power hammer would have had these done 2 hours quicker.

AJ Chalifoux 57 Posted July 20, 2019 Share Posted July 20, 2019 Finished a small hunter, a small scramseax, and mostly forged out a short Messer in the vein of Pieter Bruegel's paintings. Normally I wouldn't forge in weather like what we've been having, but I volunteered to do demos at a summer festival 3 Link to post Share on other sites
Brian Dougherty 1,167 Posted July 21, 2019 Share Posted July 21, 2019 Can we all say "stress riser" boys and girls? I knew you could Actually, I had a pretty generous radius where it broke. I got greedy with a test fit of the other parts after only one tempering cycle, and it snapped. Oh well, the grain was nice, although I don't know if that matters for a spring.

Gary LT 106 Posted July 21, 2019 Share Posted July 21, 2019 Charles your forge design / shape caught my eye, especially the Venturi. May I ask who the supplier is as I would like to see what one would cost. Also if you are running propane or natural gas, how many pounds or kgs. did it take to reach 2600 degrees. I am building another PW forge as. Am tired of the scale from this blown ribbon forge I built. Thank you in advance. Gary LT Link to post Share on other sites
Alex Middleton 499 Posted July 21, 2019 Share Posted July 21, 2019 On duty at the fire station tonight and I'm tired of the disgracefully dull knives in the kitchen drawer. I brought my sharpening kit with me to rectify the situation. Took me over an hour to get these back in shape (had to resort to the bench grinder for a couple of them), but they're good to go now.

Gary LT If you have a lot of scale buildup, you should be fine tuning your mixture. Do you have a needle valve on the gas and a gate valve on the blower line? Link to post Share on other sites
jheinen 41 Posted July 22, 2019 Share Posted July 22, 2019 A hot one in the forge today. I forged out the Journeyman presentation blade I'm working on. 2 Link to post Share on other sites
Gary LT 106 Posted July 23, 2019 Share Posted July 23, 2019 Hi Joshua, I use a needle valve and a brass valve gate. Both will give me pinpoint delivery of air & propane. I experiment over and over to light and keep the combustion in the forge itself, using 2300 kaowool and multiple coatings of kastolite. (1/4”) I can light and maintain combustion with 5 lbs./ft2 however no wiggle room to lessen or increase the propane or air as the combustion goes out. Then it’s a nightmare to re-ignite. I changed all piping and and couplings and still the same issues. Initially I forged wrought to 1095 when I first built it, 1084, 1095 as rat-tail joins but excessive amounts of scale. The inside dimension is approx. 4” square and I stack enough to maintain heat on the billet. Beats me but I am rather sick of getting started on a project and then tweaking in vane. Thanks Joshua any continued advice is welcome! Gary LT Link to post Share on other sites

I am building another PW forge as. Am tired of the scale from this blown ribbon forge I built. Thank you in advance. Gary LT Hi Gary. The forge is home built from a decommissioned 13kg/29lb propane tank. It’s lined with 2” Vitcas ceramic fibre blanket and castable. The venturi is a 1” BSP long venturi Amal butane injector (http://amalcarb.co.uk/amal-gas-injectors.html) as advocated by Tim Gunn; fitted with a 1” BSP stainless pipe. I run it off a 47kg/104lb bottle. Unfortunately I have no idea how much it took as I don’t have a way of weighing the bottle - not much I would think. I was really just doing the burn in so had it on and off a couple of times when I decided to stick the thermocouple in to see what the temperature was. It was running at 1 bar at the time and there is plenty of scope to play. The Amal injector as a lovely knob for accurately adjusting your air intake and a set screw to keep it there when you are happy. Hope this helps. Link to post Share on other sites
Gary LT 106 Posted July 23, 2019 Share Posted July 23, 2019 Thank you Charles! That’s exactly what I was looking for. I do remember the name Amal which I had seen before, so I will look them up. At one bar the equivalent atmospheric pressure in lbs./ft2 is 14.5lbs. That is certainly do-able to forge weld in my humble shop. I have a smaller forge for every day forging. I do thank you.
