Timothy, Thank you for your reply and very nice to hear from you again – I hope your Canadian winter is not to cold - our summer is a bit strange lots of cold (20 deg C ) wet days a few in the high...

I have a dyna 4400 still happily working under SKIP control. My tool holding is via ER collets. Largest size I have is ER 32 (20 mm capacity). I have a lot of 1 inch shank HSS cutters and even a tool...

Adam,
Sorry for the delay in getting back to you but I have had an internet connection failure plus, and despite my advanced years, I still try and earn some sort of living and I have...

Whilst sitting in front of the TV I realised that the only possible arrangement of 80 washers is indeed the 20 groups of 4 (()) etc. The length of the washer stack varies considerably if another...

Adamflyer,
A few comments re your last reply:
Firstly you three pictures did not come up which has limited my ability to comment fully.
#30 sand impresses me as being rather...

Adamflyer,
First let me say that I admire your courage in attempting a cylinder head casting and your tenacity in sticking at it. The automotive industry has been casting such...

Well I finally bit the bullet and pulled the Bellville washers from my spindle. It’s clear that there are at least two different designs of the spindle in this area. XWalt’s #20 has a left hand...

Timothy,
Greetings again from the great southern land.
Re those rotten die cast "T" fittings, Yep, I replaced all mine - a couple broke and the rest were cracked. You sound...

Walt,
Am exhausted from making castings all day so will reply in more detail tomorrow (or maybe the next day as I have to cast tomorrow too) but for now try
Disc...

Walt,
I managed to get at my Dyna and remove the pressing bar mechanism, the attached pics show what the top of my spindle looks like. Item 20 and the O ring that sits in the top of it are...

Walt,
Thank you for your excellent work. Is item 20 shown as the third from the left in your pic a single thing rather than made from two or three bits (aside from the O rings of course)?

geahr,
Re pull stud, first be aware that many drawings out there show the angle under the knob as 60 degrees it is actually 45 degrees

Timothy,
Its still hanging!
Any chance that you could be persuaded to dig out those photos to show us what you did and how it went. Please, I would love to know!

Timothy,
Hi again from a cold wet Melbourne Australia – loving the cool in my little foundry, but you can have the “wet”!
I too share Marty’s enthusiasm for finding out...

Bada,
On second thoughts you could ask about the Aluminium-Magnesium, alloys 214 and 220. These may anodise better. But they are difficult to handle in the foundry and you may not find...

Bada,
Years ago I worked for a brake parts manufacturer. They semi hard anodised their master and slave brake cylinders. These were gravity die cast from either 356 or 319 alloys both of...

CNC Bill,
The fittings that I found were exact matches for the originals. The two photos attached show Firstly - a new three way fitting installed near the oil reservoir and as you can see...

Mmedina,
My apologies for taking so long to come back to you but I had trouble finding the necessary photos. As you can see from the photo of the yellow oiler tube I had exactly the same...

mwood3,
To be honest cast Al for a lathe bed is a dreadful choice (sorry but there is no other way to put it). Apart from softness the main problem with Al is that it has absolutley no...

Sagada,
The other person that I looked at that transistor for was "Gelos" he is in Poland and he was on the Yahoo Dyna forum. From What he says he used part number BU 932 R as a...

Sagada,
Re the 6 diodes in threephase rectifier - yes I had exactly the same problem and I too replaced all 6. I had to make one new Aluminium plate as like yours it was badly burnt and...

Sagada,
I have a manual for the sd 3060, If you require It I can scan and send but it might take a few days to get it done. Note that it does not list and of the components. Will try...

Caprirs,
Thank you for posting the Pics and DXFs.:cool: Somehow I think that in the not too distant future I will be going down the replace the washer road and no doubt these pics and...

Timothy, Capris, Send me some of that 4 deg C please it was about 34 Deg c here today and as my main thing is foundry it's a bit hot - Love those 14 deg c days best.
My dyna manual has a crude cut...

Timothy,
Hullo again, How is the weather in Canada? Loverly sunny 23 deg C day here in Melbourne!
Yes I have had a bit of a problem with fretting too. It seems to occur more towards...

Tim,
Please, please convert all that info into PDF's. It would be a great help. Make sure that you include all those penciled in notes as they look to be info/corrections hard won by...

Lyn,
Do you still have any of the "no longer required parts" from your DM
4400?
I am interested in the APU board and possibly the removable controller.

Martin West,

Andy,
I agree with dancer - SEI Carbide is the lot to try - quality good, prices reasonable, huge range. I deal with

I got a copy of the DM4000 / DM4400 Operating and Programming Manual
with my machine. However it was a very poor photo copy. It was so hard to read that one had to put all ones effort into simply...

Hi to all,
This is a post for those of you curious about whether I managed to get my DM4400 to respond reliably, thus it is a continuation from post #127.
The short answer is that No I haven’t -...
