Ironworm throw pillow12/28/2023 just have to get the idle wheel box and band wheel installed to see how high i need the structure above the saw beam to clear the blade and guards. i think that should work for part of the eng support structure. Iv got 2 solid 9' sections of left over 2x8x1/4" sq tubing from my first frame bed build that i had to cut apart and start over. plus i will put a turn buckle or eyebolt on each end of the chain for fine tuning and not running out of tensioning adjustment as fast. I'm sure its over kill, but #40 double roller on all 4 corners should do the trick. I'm just trying NOT to have grab the back vert supports, which is my i was thinking of using another jackshaft and roller chain. ![]() So instead of both the ring and pinion having a spiral bevel gear, its a straight tooth gear on the o/p, and a worm/cock screw on the input.Īs for a spring, i was thinking about doing that, but i don't think i will need it. The gear boxes WM uses on their 30-70 models are kind of a rack and pinion style, of more so, a helical/worm gear style gb.Ĭast Iron Worm Gearboxes | AutomationDirect If I'm not making since as to where I'm talking about linking the chain, i will do my best to draw it, but i SUCK at drawing plans, but i can read them, and i SUCK at conveying my meanings/descriptions.īut basically, how the saw head would lift, i would do the same for the back of the motor structure, and run a roller chain, off the sawed beam jackshaft, reward, to the support structure jackshaft, and mirror the sawed beam lifting mechanism. I know, timing the 2 roller chains may be a fiasco, but in the end, it may be the better choice for longevity, until i can find suitable replacement engine that doesn't weigh 2x more than a 38 hp kohler gas burner. YES!!!, it will require a LOT more double roller chain, but it will help share the load of the sawed beam and motor structure. Question is, would grabbing the back 2 supports be beneficial for load distro, or grabbing the rear motor support structure with a set of roller chains and snaking it through the sprockets to either a single, or maybe a sec jackshaft placed above and at the back of support structure? i may have to grab my back carriage vertical supports to help disperse the load on all 4 corners, not just the front 2. I'm thinking bc of the weight of my power plant, and where it will need to be located (won't know any rough locations yet, until i get the raise/lower linear guide boxes built and installed) to keep the drive wheel shaft within acceptable length and location, either behind the band wheel, or behind the carriage vertical support. Now, I'm still not sure if I'm going to use a winch or utilize the same motors and gearboxes WM uses. after looking at an LX150 that was loaded and ready for delivery, i found out nearly everything i need to get my lifting mechanism up and going. for the longest, i couldn't figure out where the "extra" chain would go as the head if lifting. So, i visited the portland, or WM the other day and finally figured out the lifting mechanism. but iv got 1 fall already, just need to buy another if i can find a sprocket to fit the chain. may be less cost and fabricating to using that method. which heyyyy, they already have the chain installed on the chain fall, just find a sprocket to fit the chain, run chain to connecting tube, run a loop from a hand crank, or lighter duty electric motor, and go to town. ![]() but what about running opposite? those chain falls/hoists have a leaver that has to be moved to change direction, or, pull the chain the other direction. a double chain hoist, with a crossover tube connecting both together and a single sprocket and a loop of chain run to a winch. mount it low, use pump, mount it high, use water hose. so mount it on the bottoms, and use a low psi (NMT 15 psi) fuel pump to push fuel upwards. i was going to mount my fuel cell at the bottom, on the outside of the carriage, so humping 1-4 5 gal jerry cans, 4, 5 or even 6 ft in the air to fill them sounds crazy. ![]() I think finding center would be easy, but it would be keeping that cg nearly all the time, to prevent binding on the guide rails, and i think i can do it. it seems most of yaw are 3hrs ahead of me. Saw your post and was getting around to the replies.
