Murad Bormilathe

[Roderick JenkinsParticipant @roderickjenkins93242]

There is a Murad Bormilathe lurking on ebay at present **LINK**

I have no connection whatsoever with the vendor, just a heads up for the lathe buffs (at the risk of upsetting anybody who has spotted it but is keeping a low profile)

I noticed this and thought it looked somewhat molested and incomplete.

[egaParticipant @ega]

Apparently went for £470 so you were right that there would be interest in it.

Hello folks

I purchased the Lathe delivery on Tuesday hopefully it will service my needs ,looking forward to having it.

Well done, Eric

An interesting machine …

I look forward to your 'review' of it

Hello Eric,

It's a fascinating concept, I hope you enjoy it and get good use from it.

[Roderick JenkinsParticipant @roderickjenkins93242]

Yes, please keep in touch and let us know how you get on with this fascinating machine.

Cheers,

Thank you all for your interest and comments.

The lathe arrived on Tuesday, the former owner as had the lathe for the last twenty years and has now moved up to a larger lathe. It was in far better shape than the flea bay photo's implied and came with 4 change gears, 3 of the guards and the lead screw dial.

I shall give it a good clean check for wear and mount it on a bench and let you know how I get on and what needs attention.

regards Eric

That's a great start

Well so far so good.

Seems to be in a fair condition ,I have not run it up properly as yet as I need to change the oil in the head stock bearing housing .

The change gears that came with the lathe are 16DP whilst the gears on the lathe head are 12DP At the moment I am try to find out the details of the gear change banjo that was used on the lathe.

The one thing that I can see being a pain is as both head and tail stock at movable in the vertical axis, is setting headstock to tail stock after any adjustment ,for this reason I have ordered a Dial Co-Axial Centering Alignment Indicator.

This little lathe fits perfect in its new location, yes it was a good wedge but it is already keeping me mentally active ,I spent a good number of years as a maintenance fitter and coded welder so looking forward to making swarf in my sanity box.

Regards Eric

[Eric ArthrellParticipant @ericarthrell78468]

Made progress tweeked and cleaned all slides fitted new gib screws .

One thing that is puzzling me is .according to literature the largest lead screw driven gear is 100t at 12dp this would give me a gear dia of 8.5 " it will not fit inside the guard case. The gears that came with the machine are 16dp, 100 teeth gear at 16dp =6.375 they will fit.

I can only conclude that the spindle stud driver is at 16dp together with the rest of the change gears up to the lead screw and that the spindle gear driven is 12dp.

does this seem logical?

Very

I guess you need to find some photos of the original.

Thank you for your reply Michael.

Looking at the photographs visually, I think I am on the money and it is they way I will proceed .

Quick up date

Chuck stuck fast, Working on change gears and banjo's to enable me to turn1-7/8"x 8TPI .

Managed to source a 1-7/8" x 8tpi face plate, also most the change gears to enable me to turn the required thread form, if I have to turn the back plate off and turn a replacement.

It will require a extra banjo due to the ability of the head stock to raise and lower.

The compound slide as more slack than you no what so will need sorting. Was it worth it ? you bet first time my mind as been in overdrive for a long time .

[HopperParticipant @hopper]

"Sanity box" luvvit. So true. Keep us posted on your project, sounds interesting. ISTR the son of chap who made the Bormilathe posted on this forum a few years back. Some interesting discussion of the old chap's colorful background.

[Speedy Builder5Participant @speedybuilder5]

Certainly an interesting lathe, but why were the headstock and tailstock moveable in the vertical plane/ If there were a slotted cross slide, I could see that the headstock travel would be good for milling. But as a lathe, once the headstock height was altered, then the lathe tool height would have to be changed on the saddle cross slide. Perhaps someone could enlighten me as to the usefulness of this lathe.

Bob,

There are some nice pictures of the slotted cross slide on the page that I linked previously.

Once you find a fast solution to fixing this issue then it will become an annoyance of the past

The only problem is that so few were made you are unlikely to ever have a Murad Bormilathe community to help you along with issues like this

[Clive FosterParticipant @clivefoster55965]

A traditional way to provide repeatably fixed positions to decent accuracy is to use taper dowel pins in reamed holes through both components. Obviously destroys infinitely variable adjustment of the screw and slide system but for pure lathe use 3 or 4 centre heights should be more than enough in practice. Fixed heights makes it easy to sort the tool on centre line issue by simply making a set of spacers. One for each height setting. Means drilling holes and spoiling the originality of the machine. Would be somewhat unfortunate if a hole is misplaced too.

Pull the headstock pin when vertical milling traverse is needed.

An alternative that would probably work almost as well would be to clean up the bottom faces of the headstock and tailstock castings along the tops of the L shaped supports so that they are smooths and each pair mutually true. Spacers could be inserted and the head and tailstocks wound down into alignment. A magnet on the spacer seems a good way to keep it in place. Theoretically best practice is to either let a round bar in top and bottom of the spacers or to accurately chamfer them to narrow contact faces. Line or narrow edge contact onto a wider face being potentially more accurate than contact between two wide faces. Whether the difference is, in practice, of any import if the job is done carefully I know not. Maybe making the spacers in two pieces with provision for adjustment by inserting shims or sliding angled faces across like an adjustable parallel would be a better Home Workshop technique than trying to make everything dead accurate in the first place.

The actual headstock can be locked at a required position the use of a dial comparator makes the alignment of the tail stock straightforward .

the lathe was purchased for its ability to used as a bor mil lathe for basic machining ,I have been using the ability of the head stock vertical movement to cut the new gears required to replace the missing change gears .

I shall fabricate the gear banjo's, machine a new chuck back plate with an 1-7/8" 8TPI thread, remove stuck chuck "machine off as last resort" which will release the full potential of the little Murad.

I have retired from a working life in engineering ,time served indentured apprentice at John Thompsons Boiler makers worked their most my life as:- draughtsman ,boiler maker, fabricator ,maintenance fitter, welder. Had to change jobs as the work gradually declined. The lathe in the Mars shop was so big the turner had a table and chair on the tool post it's a housing estate now.

Let us know how you get on with it, Eric.

Hi Eric, I'm very impressed with the Mars lathe with a housing estate on the toolpost.

Congratulations on your purchase, very nice and unusual machine.

There is some information on http://www.lathes about other combination machines, it's worth looking at these. Some of the accessories may give you expensive and time consuming ideas.
