Hi all, I have a query that I hope you can help me with, I was wondering wether the sieg x1L long table with the corresponding long lead screw will fit my machine ?

I used to have a problem with parting off on my Myford , I tried various parting tools, hss,carbide and a tipped parting system ,these all failed and through research and trial and error ,I found that the following all contributed too ' chatter ' spindle speed, width of parting tool, work piece support and lack of coolant.

through my own experience the latter all helped , a low spindle speed ,a form of coolant ,I use wd40 on aluminium, a thin parting tool ie 1.5 mm ground from hss and locking the saddle and parting off as close too the chuck as possible all helped ,personally I found a rear tool post has to be the most effective way of parting off , also intermittent cutting causes bad chatter .

Hi Max, I recently bought a 500kg abor press from machine mart ,I originally wanted the 1 ton abor press but they didn't have them in stock and I needed one ASAP, it has shimm adjustment on the front and adjustment on either side by the way of nut and bolt ,once set up I found the quality to be good for the price ,everything I saw in machine mart was porley assembled which kind of put me off ,but I took the risk and I'm pleased with my purchase .

Thanks Brian ,the info you supplied is much appreciated .

Thanks for all the replies intersting reading , I checked the bed with an engineers level before I adjusted the tail stock and shimmed accordingly , my ml4 must be a late model as I can adjust the tail stock by loosening two nuts and then I can adjust using the 2 small screws on the side of the tailstock ,kind of like a jib strip , I'm fairly happy with the results 0.05 mm over 200mm is quiet good for a machine of this age , at the tail stock end of the bed I have d1992 stamped ? Any info ?

Thanks , I don't know why I didn't think of doing that in the first place

Thanks for the replies , @ Paul, I don't have a centre for the head stock ,so I can't answer that question , but overal Im pleased with the results .

Hi , last week I needed to turn a shaft out of a length of 6082 aluminium 200mm long . I held 40 mm in my Pratt & Bernard 3 jaw chuck and had 200mm sticking out o the chuck supported by a revolving centre ,I proceeded to turn the bar and had a run out of 0.5mm ,not good.

I did a lot of reading up on here and on the Internet and decided too see if I could get the lathe too turn as parallel as possible ,bearing in mind my lathe is a Myford ML4 so it's approx 70yr old .

All my jib strips are tight and there's no play in the bed and the bed looks in good condition ,I then decided too hold the bar in my 4jaw chuck again a P&B chuck as I thought the 3 jaw may not be as accurate as the 4jaw and I haven't got a centre for the headstock.

I used a dti to true up the bar and also checked the run out at the tailstok end which is supported by the revolving centre ,I manage too find a happy medium between the two.

I then proceeded too turn my bar and I still had a run out of 0.5mm ,I decided to place the dti on the tail stock end and adjust the tail stock as I felt my tail stock was a long way out ,after many adjustments I got my desired results ,I now had a run out of 0.05mm checked with my micrometer not bad for an ml4

Pics of the bar measured with my vernia

Excellent ,thank you for your input , I'll get one of these bandsaws early in the new year and I'll make a table too

Thank you to everyone for all your replies . Andy is the portable saw in your link above 240v ?

If it is , I think I may buy one and make a table like you and Sid have made ,could I be a real pain and ask if you have a link for the Milwaukee portaband blade ,thanks in advance Kev

Thank you for the link Andy , do you know the actual weight of the bandsaw ?

Thanks chris , that was my main worry with the chop saw ,any other suggestions chaps ?

There are some small, hand-held bandsaws around that can be mounted to a base with minimal effort and are relatively inexpensive - see pic.

 

I did this originally until I got a used 6 x 4 and then sold this one. It worked satisfyingly well. At the time it cost me $40 (on sale) at HarborFreight in the US when I was on vacation there.

Im on the look out for a bandsaw, I went to machine mart today and looked at the Clark bandsaw they have on sale, not a bad machine but I only have a small work shop 10*8 shed to be precise ,I was thinking about making something like the above ,I need a bandsaw I can put under my workbench and take it out when needed, has anyone used a chop saw ? How loud are they ? Any advice appriciated thanks Kev

Diolch yn fawr Neil, Merry Christmas everyone ,after 2 whole days in the house we'll savour our time in the workshop

I'm guessing that you properly machined some 302 or 304 stainless bar as its relatively soft compared too  316, the latter is horrible to machine

I wish I went for the s7 or even the 7 But that was my own fault for not doing my homework as I though everything was interchangeable between the range ,but that's not so with the ml4 and not a lot of people seem to know or do a lot with the old ml4 .

I had a busy day making some aluminium wheel spacers

Check out my album for images as I'm unsure how to post them on a thread

Thankyou to everyone who has replied on the thread much appreciated, not only has the replies been of great help to myself but I'm sure other members in a similar position can gleen some info from here.

id like to apologies to Michael Williams as I misunderstood his post, thankfully joegib clarified Michael's post , secondly kiwi my diamentions were approx , I'm aware that Myford's in general are imperial, so to clarify 74mm would be approx 3inches and 20mm would be 3/4inch I measure these diamentions with a steel rule they were only ment as a guide .

thanks Kev.
