grrclark Posted February 19, 2018 Report Share Posted February 19, 2018 3 hours ago, ditchman said: well ive been finding out what that red thingy is in the end of the motor..............so i had the thing off...it hyas centrfugal weights on it ...which were conected to a set of points...when the motor starts...it gets up to speed then the flyweights chuck out and the points open.......... it was "chattering" on start up....full of bits of rubbish rust dust and the points needed cleaning and the contact wires...put it all back together and it starts up nice and quiet now..... I'm suspecting from what you're describing that it is a dual winding motor with a starting circuit that it uses to get it going, seeing as how it is a big old lump, very likely a series winding like in a car starter motor, then when it is up to speed that winding is disconnected through the centrifugal switch and it runs as a parallel winding.

Walker570 Posted February 20, 2018 Report Share Posted February 20, 2018 Not started to trim your finger nails yet then ditchy ? This is the most amazing forum.

ditchman Posted February 20, 2018 Author Report Share Posted February 20, 2018 had another go at it today............clamped the motor down...bit unothadox but its the way to make it easy for me to change a belt or pulley without going to a lot of fuss....put a 1/2" rubber mat under the motor like Bala said.....also screwed angle iron to the bench in front of the motor....so if the belt needs tightening ...i can undo the top clamp and slip a bit of flat plate to wedge it forward a bit....... also soon i will make a cooling bath and hand it on the side of the frame so i can keep the billet cool.......... there you go..

Dunkield Posted February 21, 2018 Report Share Posted February 21, 2018 You could do with a belt sander to help with the grinding, something like this Quote Link to comment Share on other sites More sharing options...
Walker570 Posted February 21, 2018 Report Share Posted February 21, 2018 I have an old Scheppach, not that model and it has served me well, but believe that when ditchy has finished his construction/set up, it will be way better. Quote Link to comment Share on other sites More sharing options...

JDog Posted February 21, 2018 Report Share Posted February 21, 2018 Yes you are keeping busy, us entertained and your mind off other things, albeit temporarily. Keep up the good work.

Harnser has the first..........he will be an old man time he gets it ..and you can have the 2nd (if you are not past it).................. im getting out of my comfort zone here...but foolishly i have ordered up a set of micro metal routing tools from Boshe..(they are not even on the market yet)...i have someone in the know who has connections with Boshe............. and im tempted IF I CANT GET THE BLADES RIGHT............i will start deep engraving the bronze and brass pommels/gaurds...with ivy leaves or sugar beet...ears of corn and such like........................but dont hold yer breath...

old'un Posted February 21, 2018 Report Share Posted February 21, 2018 Would it not be easier to have the motor on a hinged plate for belt/pulley adjustment? I can do you one of my technical drawings if you like? Quote Link to comment Share on other sites More sharing options...

ditchman Posted February 22, 2018 Author Report Share Posted February 22, 2018 done a bit more today.............i couldnt be doing with looking at that "off-centre" roller....so had that spun off by nick in lowestoft...and at the same time picked up the flat bed raiser...(see that in the last 2 pics where im holding it in more ore less the roight place) started it up.....much better no vibration...took a lot of metal off that off-centre roller....still got the "chattering" on the guides which i will add weld to and file down tomorrow....when i put pressure on the guides it stops chattering and all you can hear and see is a slight vibration...and hear the "HISSsss" of the belt as it slips over the old bed.....so the only job now ios to do that..and get some new belts ...as this one is totally knacked....it says on the underneath "MADE IN WEST GERMANY"..so it is a few years old ...it will run straighter when i have a new belt on.......then i can round off the transition points on the bed raiser to suit the angle of attack of the belt..... thats yer lot today........christ it is getting cold here...temp has dropped summat chronic...........
