Hi Howard

from what I understand it’s acceptable to mill up to 5mm of the top of the ml10 compound so I can’t see it being a problem the only reason for it is to get to centre height with a bit of adjustment, there is already 2mm off the tool bit holders but it’s not enough I need another 1mm or there abouts.

Dell

Okay after all the comments I have decided on a course of action, let me first explain that when I contacted Peter @ PeWe tools told him what I had he suggested the size Aa but said mill 2mm off the bottom of the tool bit holders , I have Glanz indexable holders and HSS bits so I took them to my local engineering company and they mill 2mm off the bottom ( he said they were bloody hard ) but upon resting tool post and holder with tool in it was still thereabouts 1mm to high hence having 2mm off the top of compound ( I understand it’s okay to take up to 5mm off ) .

what I have decided to do is turn the original stud down to 10mm apart from the shoulder that will sit in the compound about 9mm after 2mm has been taken off top of compound, it shouldn’t be difficult to hold stud because it’s way to long for what I need I will just need to put a centre In large end to locate rotating centre then turn down to 10mm the hard bit after cutting to length will be holding it to thread, what thread to use?, would a course or fine ?, I have M10 in

M10X1 and M10X1.5, then make a sleeve 18mm o/d 10mm I/d 14.5mm high, I have a 10mm reamer, I hope that all makes sense if not please let me know, an suggestions on holding for drilling would be helpful as well please.

sorry if I have rambled on but I am used to making small parts for torsion clocks mainly using a graver so am not used to making or modifying larger parts but I will get there and your help is much appreciated.

The trouble is the hole in the compound is only 11mm or whatever that is in imperial that why I can’t use the T nut idea,

pas for milling 2mm off the top of the compound, I understand it’s acceptable to mill up to 5mm off the top the compound is 14mm thick .

Dell

So you think maybe 8mm would be enough internal thread , I could possibly drill most of the way then grind a flat for last bit so like an endmill?

Sorry for the confusion I just meant I didn’t want to bore it, if you look at picture it’s the bit top centre that I don’t want to bore

DC32k

the top bit will have just over 10mm internal thread , I don’t want to go much deeper because the bit that goes in the counterbore is only going to be 14.5mm.

Dell

Thanks for the replies

the largest part of the bit I have made doesn’t really do anything apart from sitting in the counter bore in bottom of compound so I am wondering if I put a couple of parallels in the chuck for the part to sit on while I tighten it up then remove thee parallels of course, I only need to turn one mm off for 2mm .

I was typing when I see your post great minds and all that.

Ian P

there was no specific reason for making it in to parts other than I didn’t want to bore the holder out again mainly as I haven’t done any boring yet , so I would either have to make a one piece shaft and a sleeve or how I am doing it because the Multifix has a 10mm hole in the top and an 18mm counterbore that is 14.9mm deep .

Hi everyone
Can I pick your brains please, I have done my first bit of tuning on my Myford 10 lathe this morning, because I am fitting a Multifix tool post I am having to make a new post so I decided to make it in two parts , I have made the bit that is going in the compound from the bottom but I made a bit of a boob , I am going to have 2mm milled of the top of the compound and I forgot to take that into account so I have to find a way of mounting it to turn the shank down 2mm,extending the thread won’t be a problem though because as I have the thread already I can do that by hand.
Anyone have any suggestions because I don’t really want to make it again.
Dell

I can’t believe how quiet it is compared to the original motor, I have faced both ends of a bit of stock but I need to make a new shaft to be able to fit the Multifix and although I have had 2mm of the bottom of my Glanze tool holders it is to high by 1mm or there about’s so I think I am going to take the compound or is it crosslide never sure to a nice man I know that has an engineering company to get 2mm milled of the top.

I have a busy weekend as this all turned up yesterday, wife said that should keep me out of mischief for a while.

i forgot to say my 6’X6’ cubbyhole has all the gubbins for my central heating so it’s never cold in there, although it is in the wood shed where I have my mill.

Dell

I have been spending money like water, Multifix coming from PeWe tools ( same as I had on my Pultra) , Newton-Tesla motor and inverter kit, as I wanted some way to stop it in an emergency it seemed silly to pay for that as I was going to upgrade to variable speed later anyway, Genuine Myford swivel milling slide for £75, both fixed and travelling steady for £110 didn’t need them straight away but as I got both for less than cost of a travelling steady I couldn’t turn it down, so getting there slowly.

bobcha

its a real lathe to me anyway it’s the biggest I can get in my 6’X6’ cubbyhole and I hopefully will be able to do more on it than on my Pultra although I am sad to see the Pultra go but I don’t have room for both.

Dell

Not sure I got the runout correct I said the collet chuck had just short of 1 thou runout ( above ) but that was using my verdict gauge and I just noticed that my other gauge was 1 thou increments and I thought the verdict was the same but it’s not it is 0.0005” I think that’s 1/2 thou if so the runout is just less than 1/2 thou.

please correct me if I am wrong.

Dell

Received the ER 25 collet chuck checked runout just short 1 thou , tangential tool holders finally arrived from Australia , just waiting for Multifix from PeWe tools now , the QCTP that is on it is next to useless, can’t get the tool on centre although I probably would with 6mm tooling .

Dell

That’s good to know Bernard thanks

sorry Robert I mentioned it to a friend as well and he bought the last one.

someone on another forum mentioned apt they have a set quoting maximum run out of 0.005mm for £80 odd so that seems a good deal because cutwell are saying £185 quoting same.

Purchased this collet chuck made by Myford but to take ER 25 collets, just need to get a semi decent set of collets, I know there are literally 100’s out there but for what I do ( clocks ) I can’t justify spending 100’s£ but I don’t want Chinese ones so if anyone has any suggestions it would be much appreciated, I know it’s possible to get Myford collets but they are one size collets whereas ER will hold in between size stock albeit not quite so accurately.

Dell

Collected lathe today, is it heavy or what but got it In it’s cubbyhole, need to level and bolt it down but had enough today, it’s a pain getting old ( or should that be older ), I think the cover is for a larger Myford, I was and am happy with the Pultra but lots of tools I want to make I can’t do on the Pultra.

Does everyone else have to login every time ?

I can’t believe how clean it is here are a few more pictures
