You may get an over heat alarm not sure but you can switch off the motors individually in Parameters I can vaguely remember bits of how to do it but dont want to tell you incorrectly I do know most of the problems came from the fans , Y axis motor or the the tool changers shuttle motor it used...

Failing that try disconnecting one motor or ancillary at at time to see if it will reset you will get a error code for what ever has been disconnected but the error 175 should go It was in the 1990 working for a company named Perlos that I did a little work on those machines I do remember a...

Cromwell Tools in the UK are currently selling hand chasers at a discounted price I have hand chased fine threads in brass in a former life but always found it a butt clenching experience We used to polish the threads to a near perfect fit although sometimes I think it was just to keep the...

From memory, the cooling fans also come under that code as does the 115V power supply Thats all I can remember about them although the fan was a common culprit as the company used a lot of Graphite

I have a few early tools over 130 years old that are stamped W F ,Whitworth Form from the days when whitworth was the only standardised thread . I think its to show the tool is to the standard 55 degrees for Whitworth and British Standard Fine and just to confuse during ww2 they shaved a 1/16...

Works OK this end

Make a piston ring clamp, just some shim or beer can and a hose clip Iv still snapped a few rings though You wont get an accurate measurement of the bore using vernier caliper as the jaw overlaps so you measure a chord https://www.machinemart.co.uk/p/cht257-piston-ring-compressor/

Hi Ken, good luck with the build Im basing the Ringbom on one Iv already made designed by Renee Schaffer the spelling maybe wrong but you can see it here. Iv also recieved some info from Huib Vissor so with a bit of luck it should run this time

Some good animations on this site including the rotary cylinder engine Im on building a Ringbom engine version.Well Im onto Mark2 Animated Engines - Home

Hi Bob, four years by time does fly I cannot add to what youve already said air leaks and friction kill these engines For the piston seal Iv just used plumbers PTFE tape not very technical but it has done the job . I did find a couple of air leaks on my engine one was at the mounting for the...

The valve is basically a needle valve that creates an air leak that slows the engine down On the original engines and on the Hienrici engines they have a snifting valve a bit like a safety valve just backwards.Just not got round to making it yet and the needle valve works OK When I first fired...

Hi, my engine with pump attached will run from one 6mm dia wick meths fired and the speed needs regulating to make it run slower or it flys away From the videos she looks a bit tight if not then try and see if there is any air leaks When cold the engine should turn freely and at one place have a...

Had to part four bits of round 65mm dia alloy today and using Geo Thomas rear tool post it was a walk in the park unlike the butt clenching memories pre rear tool post days Buy the book and a whole world of well designed tools will be available including his tool setting gauge and most canbe...

From memory , the headstock is held onto the bed with four M8 bolts .These are inside the casting so you need to remove the covers The headstock is held in alignment with a key, on the lathe I repaired it was a very sloppy fit The tailstock is usually the culprit

The Model Engineers Workshop has to be one of the best for kitting out a Myford and making the tooling as you go can be a great learning experience. I know the book is not cheap but it is full of gems Harold Halls web site also has some nice bits of kit for the Myford and I find his headstock...

The spring is 0.625 OD 0.750 long the wire its made from is 0.90 dia and it has 7 turns The radius ed washer is 0.9 dia the through hole is 0.563 and its 0.375 long I measure the rad at 0.437 Should you want the hex nut is 0.706 across the flats 0.75 long and threaded 7/16 BSF not that you need...

No problem, I will try and find it tomorrow The few nuts and bolts needed can always be made on the machine once you have it installed Tracy Tools in the UK supply mid ranged taps and dies .I have never had a problem with the company or any of the kit they sell over a lot of years

Youre also missing the spring. It fits around the mounting bolt and just holds the clamp up I think Iv still got one hiding somewhere if you need the dimensions. I have never needed to use that clamp for the last 40 years but still use the original 4 way tool post. I have a genuine Myford quick...

Never seen the O ring mentioned on a ML7 Myford as in the original factory did offer an updated headstock spindle and bronze bearing kit.The spindle was hardened I replaced the bearing on my last ML7 around 12 years ago and seem to remember paying about £200 for the kit. Had a lot deeper...

One of the worst features of the Myford and one that often has me spitting teeth is the small through hole in the headstock spindle.For the size of machine its ridiculous This should have been addressed long before they eventually did They also removed a lot of mass from the beds on later lathes...
