A few weeks before I got slapped with an unknown disease in Nov 2019 ( seems it was COVID19 ) I was power cross cutting a nogging of steel , just as I pulled the disengage cross slide gear knob the sodding bakelite knob pulled free ,Consequently a few milliseconds before I hit the emergency stop button the slide crashed at the front end of it's travel , breaking a die cast sliding driving dog for forward & reverse in the simple forwards & reverse gear box .
I tried to cast a new one in good quality aluminium from a 3D printed form ( Thanks Daedalus ) but it never worked well as I really needed a centrifugal spinner to ensure all the tessellated teeth were fully filled & formed . ( Next project ?)
In the end I bit the bullet and purchased a used part from the USA .
Eek kin'ell , it cost me more in P&P than the 30 dollars USD it was priced at . £65 by the time it landed in our letter box some four months later .
Meantime the cheap supposedly 1/3 HP Machin Mart replacement motor I put on it to replace the 75 plus year old original 1/3 HP one that melted because of drawing alu swarf in the air intake died a spluttering shuddering death with a dead short internally blowing the trip in he consumer unit .
Pocket money projects had already spoken for a few things for the next couple of months so getting a new motor went on the back burner till recently after posting about the dead Machine Mart motor .
Striker told me he might have a 1.5 hp second hand 240 volt motor for sale , " With a 3/4 drive shaft " .
Business done I got the motor on Saturday afternoon , hadn't time to do a test run or load test so had to wait till Monday
Thank god I clamped the motor down to my 250 kg plus welding bench . It nearly took off when I flicked the power on . Careful examination of the data plate indicates it's a 1.75 HP induction motor running at 1440 rpm
I spent the last two days sorting out the difference for the foot plate foot print as my old antique lathe is all imperial the replacement motor is metric ,m got it connected up late last night .
I Much of today was spent rebuilding the carriage gear box and setting the change gears & banjo mounting plate up , gave every thing a decent lube put eh drive belts on and held my breath as I pressed the start button .. Nothing , sod it ! I'd not turned the circuit breaker back on , rectified , it flew into action perhaps the quietest it's ever been . I just love the repaired carriage drive & reverse as I keep getting RA & OA in my limbs & joints . Spendinghe rest of the day hoovering up the crud left after I emptied the bits & bobs 600 x 500 fish crate full of all sorts of , " Valuable materials & useful some day parts " Final curtain today saw me using two old extractor vent stainless steel covers to work out how to make , " A catch all " easy to clean long urinal style gutter to fit to the back wall behind the lathe so I can lever the lathe back onto the lower lip and prevent stuff dropping down behind the lathe . At 71 & being well wreckedit too much to think of me ever having to pull the lathe out to clrn behind it of find tiny Delrin plastic parts that have " flown the chuck "
Piccies to follow when nit's all done & dusted as well as me having to clean up the mancupboard .
