Hi Folks,

Friend of mine has a small Hauser Jig Borer, lovely little machine. Trying to find out what collets it uses.

the lathes .co.uk shows a very similar machine under the heading Other Machines, It does not mention the type of

collet but it shows a horizontal machine and says it has a spindle which takes 9 mm Schaublin collets (draw-tube retained).

A horizontal machine is shown with a vertical attachment which looks very similar to the spindle in the picture I have shown below.

I have never heard of a Schaublin 9mm collet and wonder whether it is a typing error.

Does anyone have any knowledge on this machine.

Many Thanks,

Colin

That is an interesting one, Tony's implies its a vertical mill, but it does have the moving Z like a jig borer. I would think it highly sought after, both because its rare and its Hauser. I've an M1 (i believe their smallest jig borer) and it takes 8mm Schaublin collets - the same as you put in a Schaublin milling attachment. I have no idea if that one is the same. Know anyone with a variety of watchmaker collets to give it a try? OR try an 7.99mm dia stub of something and see if it fits?

Their jig bores also come with different spindles as well as a microscope making a very fine tool makers microscope. Incidentally there is one for sale I saw recently in the UK, really well equipped for sale and, while not really small dollars, still a heck of a lot less than most want for the M1

I just got the Hauser M1, package deal with yet another lathe and mill. I just finished painting it (the paint was literally falling off). It is the nicest machine I think I've ever put my hands on. Its in really good shape, original scraping (the best I've seen, probably 40ppi) is well defined. Graduated in the tenths with lead error correction, the precision and fit and every part is unrivaled in my experience.....I was every machine was made like a Hauser!

Photos of mine just just because its so pleased with the paint and its an excuse to show it

thanks all for the encouragement and kind words. Sorry Colin if I took it OT a bit, I got too excited when I saw Hauser Jig Borer.

Pete, The contoured piece is the thread error correction device and is on the x and y axis. Its shown best in the last photo. you can see there is a plunger (spring loaded) that runs along the contoured profile. The plunger is connected to the marker for the axis - the mark that you read a line on graduated dial against. So as you move over the length of the feedscrew, the mark moves slightly relative to the dial to compensate for lead error in the feedscrew. Each graduation line is a tenth and its is suppose to be accurate to tenth corner to corner.

10KPete · « **Reply #7 on:** February 27, 2018, 06:16:38 AM »

Well I'll be! I'd never heard of such a thing but it makes perfect sense. Without electronics there must be a way to compensate for deviations in the screw. Amazing stuff.

Thanks,
Pete

Mcgyver,

No problem going OT. You have made a beautiful job of that borer, the paint looks fantastic. Better than new ??

My friend has one of the large Hauser jig borer as well as the little one. I may try and take the little one off his hands.
He wants to get rid of it. I think your possibly correct that it is 8mm schaublin collets. Bit of a shame as I have a small selection of
W12 collets for my Aciera F12 but no 8mm ones.

The jig borer does not have a motor with it so that would take a bit of thinking about. I do like the little rotary table on it.

My colleague also has a BCA jig borer (with all the bits) on a stand he wants to part with, but I just do not have the space, plus
I would get crucified by the other half. I sneaked the Aciera in as it was.

Mcgyver · « **Reply #9 on:** February 27, 2018, 03:54:07 PM »

Colin, you have to make room!!

. As for the better half, sneak them them in in pieces under the cover of darkness

I've also a BCA and an F1 (picked up with the M1 and another Schaublin 70). Just too nice to say no to. The F1 is in pieces as, as nice as they are, I think it the worlds worst spindle design (Outer needle bearing race is the spindle housing, grrrrr). Slowly a plan is developing to restore the spindle, but its tricky. I didn't set out to buy the M1. When getting the F1, thank goodness, I took an indicator and caught the F1 bearing problem before purchasing it - the M1 ended up thrown in to the deal for me assuming the F1 bearing problem

Twizseven · « **Reply #10 on:** February 27, 2018, 08:14:53 PM »

Mcgyver,

I think I could get away with the Hauser but the BCA would be spotted immediately and I think to be honest is going to be a lot more than I would want to pay.

Only problem I can see with the Hauser is finding collets for it. I have found a couple of bits on web which mention that the small Hauser
jig borers used W9 collets, (rare as hens teeth) but I want to try ad get some more info.

One the challenges you hame imo is that i'm not convinced Hauser called that a jig borer so searching for what went in a jig borer may or may not be what you're after. My thoughts on that is that everything I've seen says the M1 is their smallest jig borer and the way Tony's site is worded it sort of implies that machine is their vertical mill. I'm far from 100% on it, maybe not even 50/50, but I thinking a reasonable probability. Maybe a more informed view will emerge.

I did double check my M1, the collets that came with the spindle are 8mm, Schaublin. (at the least the spindle and collets that came with it, the M1 jig borers had different spindles that you'd swap in and out) Unlike the 12mm Schaublin that is buttress thread, the 8mm Schaublin collets is a V thread and appears to be very much like a standard 8mm watchmakers lathe. The large end is slightly larger OD and I've not measured or blued to check the angle....but I'm thinking its pretty much a standard 8mm watch makers collet.

In the ensuing weeks since I put up the initial post, I have had a close look at the BCA. It is a MKIII on the original cabinet. It is in mint condition, all the scraping can be seen on the ways. The three phase motor purrs, its almost silent. there is a full set of Imperial collets, 6 & 10mm collets, an unused set of the measurement bars, Pratt 82mm three jaw chuck on a baseplate to fit the rotary table, Lushington No1 boring head, Lushington No.0 boring head, BCA standard table clamps and extension table clamps, small vice, Albrecht 0-1/4" chuck (looks unused), BCA milling cutter arbors, and the drawer is full of oddments such as 'T' nuts for rotary table, centring guide for rotary table and other odd bits of steel.

Very tempting.

That looks to be a very nice machine, the collets alone are worth a fair bit, just buy it and worry about the consequences later

A lovely machine , I did miss a BCA jig borer recently by 45 mins........but did get 35 volumes of model engineer from Vol 1 1898.....to 1918..........

Mcgyver · « **Reply #16 on:** April 01, 2018, 03:35:53 AM »

that looks like a great machine, I agree with 'just buy it'. Getting a bunch of collets is a treat....over here its rare to see metric cutters, probably the opposite there. I think I got two collets with mine.

The motor looks like the geared version? I took mine off and replaced it with a DC motor so I could have low and high speeds. Currently I'm making an ER based spindle for it, more flexibility.

I see an F1 in the background.....that would be another nice one to find its way to your shop. I picked one up before Christmas, still in pieces, spindle bearing problems

Twizseven · « **Reply #17 on:** April 01, 2018, 05:42:29 PM »

McGyver,

I wondered if anyone would spot the F1 in the background. I in fact brought a F12 of the same guy. The F1 and F12 used to be owned by same person, my friend bought the F12 of him and rebuilt the spindle and used it for making clock gears, he then had chance to buy the F1 and so I took the F12 off him. Have a reasonable set of collets for it. and gradually accumulating other bits. I also have a Chester Super Lux Mill, Excel Surface grinder, Cowells Mill and ME90 lathe, Myford S7 (with g/box and powered cross-slide) and Myford 7, Corbetts XL 7" shaper, pillar drill, bench drill, and a Colchester Student lathe. Guillotine, folder and flypresses also take a lot of space. Space is becoming a problem but working on it.

It is not the geared head motor, it is a 3phase 2 speed. There is a knob on RHS which has central off position and turns left or right to run slow or fast as necessary. Luckily I have 3-phase in my workshop.

I did see you were making an ER based spindle for yours.
Colin

Mcgyver · « **Reply #18 on:** April 03, 2018, 02:23:52 PM »

Sounds like a nice and growing collection!

The F1, nice as they are, has to be the worlds worst spindle design. I've a plan to fix it now, but its not simple. Like some Deckels, the spindle shaft and housing form the inner and outer races so when the bearings go, you have a real problem. The F1 is W12 of course, is the F12 the same?

The new spindle for the BCA has been on the back burner for months, but I'm almost done the soft bearing balancer, then can fix the tool post grinder, then can finish the spindle housing.....somehow the hobby has become making the machines right instead of model engines...trying to dig my way out o but have not been able help myself when nice machines are placed in my path. Only four walls (not yet padded) can contain my enthusiasm for acquiring more machines

My BCA had the geared motor, sort of looked similar, but it was single phase. The slow speed was too limiting imo. I agree on three phase, in the garage where I have the big machines I make it via a diy rotary phase converter. I always felt it gave me a buying advantage as many home guys would steer clear of it. Small stuff is in the basement, much of it is DC, but I recently put a transformer and VFD in to drive a 440V 3P Schaublin and really like it.

McGyver,

Yes collection is growing. My other half sees that as a problem. My problem is I cannot find time to use any of it at present. Need to retire, 68 I two weeks time. But work keeps coming my way.

Twizseven · « **Reply #20 on:** April 13, 2018, 09:42:13 PM »

Other half has now spotted the changes in the workshop to make space

. Told cannot have anything else need to get rid of something.

Like for instance the immaculate Lister D on a trolley.

. Nah I'm keeping it. Just have to sneak the BCA in now, not quite sure when as have RF site surveys to do most of next week. Also I need to break into my 3 phase feed to the pillar drill and divert some of the sparks to the BCA. The owner found a couple more of the adaptors for the slots in the rotary table.

The only things its missing from original spec. is the DTI's and the centreing tool.

Will put some pictures up when its in place.

Well its in the workshop. Took rather a lot of messing around though. When we arrived at my house we found that it was too tall to fit under the roller shutter door.

Drop nose wheel as low as will go, the drives slopes down to garage. Still too high. I know the head tilts. Undid the bolts, pulled out location dowel, tilted head. Still too high. Removed the pulley tension bracket, head now rotates completely sideways. Still too tall. Push roller shutter up out of guides, Hurrah.

Trailer in garage. Oh bu..er. My hoist is much too low, overhangs the BCA by a foot.

I know hydraulic lift table will do it. Drag BCA off trailer and onto lift trolley. Lower trolley. Still not enough room for hoist. Now for the creative bit, get lifting strop and wrap round side leg at the bottom, swap my chain hoist for a slightly smaller Tirfor winch and carefully hoist one side of BCA till just clear of the hydraulic table. Slide hydraulic pallet truck under the side of the BCA as pull/push it off the hydraulic table and lower it at od angle to the pallet truck. So far so good.

Now roll the pair along the floor till the other leg of the BCA is below the Tirfor winch, Strop round leg and lift until clear of hydraulic table, pull table out of way, slide BCA onto pallet truck. We are getting there. Lower pallet truck, put strop round BCA body and use winch to clear the pallet truck and lower to the ground.

All that remained was to push it into its new home.

Just need some sparks for it now (and suffer sparks from the other half) and give it a good clean.

Jo,

Sorree, You've got one already, what would you do with a second.

He has still got the little Hauser vertical mill, a Harrison Vertical mill, a Myford Super 7 and possibly a Hardinge Capstan lathe available. Also a few castings of bits for the Aciera. Also wants to lose a Scott watercooled motorbike, a Mercedes (I think its a350SLK coupe), and possible a Bentley (8??) saloon.

Been having a clean of the BCA. Coming up nice and shiny using a bit of Solvol Autosol on the paintwork. Should hopefully have t under power sometime on Monday. Managed to check the collets. Have a full set of eleven collets 1/16" to 3/8" in 1/32". a 1/4" collet threaded for Clarkson end mills, a 6mm collet and a 10mm collet. Need to keep eyes open for 3/8" threaded collet and would be nice to find 6mmand 10mm threaded. If by any chance anyone has one of the above they wish to part with (unlikely I know) please message me.

If anyone is interested there is a BCA for sale on Ebay at the moment. Item no.323228441028. Three days 22hr to go and sat at £215.

Colin

pgp001 · « **Reply #31 on:** April 28, 2018, 10:16:30 PM »

Tenga do the threaded collets at £75 each

I thought I had got a full set of collets with mine, also going up in 1/32", then I discovered you can get ones going up in 1/64" as well. I have quite a few but annoyingly not a full set.
Good luck with finding any of those. Then you can start looking for the metric ones as well, they go up in 0.5mm increments. Unfortunately if you are like me you will not be happy until you have them all.

One watch out for you.......Be careful you dont buy Lorch 10mm collets by mistake, they look very similar.........Dont ask me how I know

I was going to give then a call, I not sure I will bother now. I'm just glad its got 99% of the parts it was originally supplied with.

Colin.

PS I have been looking at the thread where you fitted DRO's to your jig borer. What did you use to make it so nice and shiny.

pgp001 · « **Reply #33 on:** April 28, 2018, 10:58:40 PM »

The chap I bought it from had restored the machine, he worked at Bentley Motors in Crewe.
I reckon he would have used a fair bit of good old fashioned patience and elbow grease.

I must admit I thought it was too good to be true when I bought it, you know maybe just a quick paint job but totally worn out.
I stripped it down completely and found it to be absolutely spot on in every respect apart from needing a new Z axis feed-screw which he did tell me about.

I reckon you have dropped very lucky with yours by the way, they dont usually have any tooling included and you end up paying as much again to get it all.

Phil

Twizseven · « **Reply #34 on:** April 30, 2018, 07:51:29 PM »

We now have power.

She runs beautifully quiet.

Am I correct in assuming that the tension should be taken off the drive belt if it is not being used.

What is the best way to do this. At the moment I have just pushed the spring tensioner in as far as can by hand and locked the clamp bolt.

As soon as release the clamp the tension will be back on the belt. Or do people just pull the belt of the pulleys on the tensioner arm.

What is he best way to centre the rotary table under the spindle? What tricks have you come up with to make this an easy repeatable task.

Colin

pgp001 · « **Reply #35 on:** April 30, 2018, 10:05:51 PM »

Colin

I normally run the belt in the middle pulley most of the time as I have it powered from an inverter, so I just pop the belt off the middle pulley onto the small pulley on the spindle to relax the tension when not in use.

As for finding the centre, I have a dead length setting bar that is used on both X and Y axis to do this quickly, it is repeatable to within a thou or so which is fine for most jobs, I also leave both the dials set to zero for that position as well so a combination of setting bar and dials gets me there, otherwise it is back to a verdict dial gauge and the centre hole clocking system if I need it to be any better.
Once zero'ed I set the X and Y to zero on the DRO as well.

Phil

Twizseven · « **Reply #36 on:** April 30, 2018, 10:36:41 PM »

Phil,

I must admit I had wondered about making some setting gauges.

You commented earlier about Lorch Long collets not being the same. Yet I have seen other people say they are. What is he difference?
