I have 100 ( 25580 ) bigger axle has a 2.25" bore . i have 4 ( ? 387 ) I have trouble with Harbor Fright parts dept , They have a 12 by 36" Gear-Head lathe . These tapered rollers are very light duty . Thats fine . BTW 518 Welder "combo" from Longevity-inc has 2 high freq transformers . parallel for stick and TIG , then series outputs for PLASMA cutting . Uses MOSFETs * 12 . .... 25 amp/500vdc Variable control also works in stick and TIG . For very thin welding , start arc at 100 amps , then turn it down to 20 amps ! NICE ! But i tossed the heavy foot control box . Strap the light wt pot to your left arm Harbor Fright $200 Stick/TIG is also variable . I have 5 . It uses IGBT in a half bridge , thus needs a huge Cap to ac couple the transformer . There is a much simpler , more reliable method . If i can cut the IGBT into 2 sep' NPN's ,ill do it someday . It has easy swap front connections , but electrodes and Plasma , are always negative , to stay cooler than workpiece . Electrons bombard anode to make it far hotter than cathode . HF has a Plasma , $650 . Has a pilot arc . i have 2 . works well , cuts a very narrow qerf in .058" steel . Crazy idea ... dumpster diving for steel crate banding , removed from big bundles of steel square tubing ... I am using 1.75" wide steel banding by 6" long as springs on a small cart , i bundle 10 of them together . Adjustable spring constant , and riding ht . sliders can shorten the length and reduce range . Old VW car used this , in front springs . Beats coil springs . adjusts easier . |
