Thread: Has anyone got plans for the reverse parting off tool holder

do a search for the southbend plans there is a company in the USA that makes tool kits for southbends. just look at the pictures they are not that hard, a big block to bolt to the rear of the slide and a tool post if you have a QCTP why not use your old square 4 tool, tool post? mount the parting tool upside down so you dont need to run it in reverse

one thing that will stop you is how to mount it to the cross slide. a T sloted cross slide was availible as an extra for the southbends any you can buy a kit to make one from that company in the USA. on Peters sheraton he put his on the taper attachment part of the slide otherwise i dont think it would be very simple

anyway good luck with this its a very cool simple project

Does anybody have the details of how the Extended Cross Slide, detailed in Hercus Text Book of Turning, is fixed to the cross slide?
Does the Extended Cross Slide replace the cross slide? If so, how is it fixed?
Frank

The only one that I have seen replaces the existing cross slide,it has its own nut and Gib.
You remove your existing cross slide and replace it with the TEE slotted cross slide.

Thank you, pipeclay
I put a bid in on one but was not successful. Outbid within the last minute. Damn sniper (a dealer).
Was the extended cross slide, detailed in Hercus Text Book of Turning, a factory part or third party?
I'll just keep looking.
Frank

It was available from the factory,I think if you could get one for under $400.00 you would be lucky.

greetings chaps. There was a plan of a crosslide posted on this site. As far a I know back on the days of yor a bloke named Lofquist published an article in Model Engineer about a South Bend (same as Hercus) crosslide. His Idea was to be able to mount the vertical milling attachment in multiple positions on the crossslide. To do this you have to replace the whole crosslide. His had three tee slots and four tapped holes spaced across the slide. A friend of mine has over thirty tool holders on his quick change system one of which is for his rear toolpost. His rear tool post had a foot on the bottom to fasten it to the slide in two of the tee slots. His was cast iron but a lump of steel would do. He also had a clutch which also came out of the ME so the machine ran all the time just like the real ones. I have a foundry pattern for said crosslide from which I made a dozen or so examples. Said examples are up and down the east coast of OZ.
One Problem I found with Hrcus was that the dimensions of each saddle varied slightly over the years. So when I did each slide I asked that the owner sent me his saddle so it could be measured and fitted.
Hope this is of help 4-6-4

I bought a British made slotted cross slide, as supplied for Boxford lathes. Fingers crossed, I bought one hoping it'd fit my 1946 9" Hercus. Well - it did, perfectly.
I see some variations in the design of these things. some have a slot in front of the position for the compound slide assembly, others (like the Hercus one) has the compound at the extreme end. Slides without a possy for the compound were also available, called boring tables.

Yes that certainly looks like the beast Mine did not have the tee slot at the front. My original had two taped holes on either side od the tool post hole. these were the same centers as the tee slots. The idea being that the milling attachment was mounted on a spacer and could be positioned across the crosslide in about 5 positions. The problem with the original set up with the hercus was the milling attacment was positioned in the top slide hole. When this was wound to the center of the chuck you had very little traverse left to mill with. The extended cross slide avoided all that .I would be interested in an aproximate cost of the Boxford cvrosslide. Did it come with a gib strip. It must look good on the machine. I have the plans for a taper turning attachment whichwas desighned by a chap called Bernie O'Dea from the Melbourne Model engineers. This requires the extended crosslide an does not need to alter the cross slide screw. I can't post it at present because of a scanner malfunction. Only too hapy to mail it if you are interested.

This place in UK sells them for 115 pounds:

I can't remember if I got it from them, but probably did. I brought it back with baggage, so didn't have to pay much freight. I came with gib strip, screws/nuts and a loose degree wheel that I attached with silicone sealant (great adhesive!) after finding correct position. It'd be a good idea to confirm exactly what they supply before ordering. I wasn't too impressed with the degree wheel at first - it's just an engraved piece of laminate. But it's actually been very good - clear and easy to read and still looks new 5 years later. It's protected by being sunk into the top of the slide, so full marks there.
I'd love the have the plans for a taper turning attachment.

Dear Jordan, I have the plans for a taper turning attachment for a hercus, and I know where there is one as we speak. I can not post it as the scanner is down and the wood show is on this weekend and all available roubles are allocated.
The basics of the beast is there is a bar mounted on two brackets which are clamped to the bed one under the chuck and one at the tail stock end. these do not get in the way of normal operations. A piece of bright MS bar sits on the brackets and is pivoted at the chuck end and adjustable at the other to give angles. A block with three bearings runs along the MS bar. On the cross slide there is a dovetailed block which holds the tool bit.This can also double as a rear tool holder when not turning tapers. To connect the sliding block on the bar to the dovetail block on the crosslide there is a piece of flat steel. this makes the whole thing work. Its a bit hard to describe. The plans come with a isometric drawing of the beast as well as list of bits. and a photo. Bernie O'Dea the inventor used what was to hand in his crowded workshop back in 91 to build the beast so his looks a bit rugged. There id a bit of work involved the dovetail block probably id the most difficult.
The major advantage is that there is no need to diengauge the cross slide screw. It also can run the full length of the bed an does not need to be removed after each use.

Many thanks, 4-6-4

Hello 4-6-4.
I would like a copy of the information you have about the taper turning attachment when you get free of the wood show and the scanner is returned to service.
My mail address is [email protected]
Frank

It looks as though the taper turning attachment could be popular and the scanner looks to be down for a while. Any one who wants a set can reach me at the PO Box in my last post. I would not object if one of these copies was posted. 4-6-4

G'day 4-6-4,
I too will be attending the wood show, not sure if it will be on Sat or Sun at the moment but if it would be possible to bring a copy with you to the show perhaps we could catch up?
Send me a PM and I will let you know my phone number or I can ring you and see if we can work something out.
I have a scanner and would be happy to post a copy.
Cheers,
Greg.
