Looks perfectly OK to me

Here's a few rear tool holder ideas for you. Mine is a small QC toolpost that I had spare, but the blade clamping can be applied to whatever style of holder you want.

The first one is for insert style blades, the bottom one is for solid HSS blades and uses a wedge pulled sideways to grip the blade.

Unfortunately due to the current situation, the marketplace may well be flooded with bankrupt stock in the coming months. I dare say there will be lots of new old stock on ebay soon.

I work for a North Yorkshire engineering company and have so far been lucky in keeping my full time design engineering job and working from home. If it was not for the fact that we are supplying machines to support the "Ventilator Challenge UK" things might be very different.

Assuming I still have a job by then, my retirement is April 2022. Who knows what will happen in the months to come though.

Phil

Just a thought........Are you looking at a "Serrated" shaft or a "Splined" shaft ?

I have always described what you have in the photo as Serrations, so you might find more information using that terminology perhaps.

My B.S. A19 from 1941 cover aircraft Serrations, but it jumps from 16 to 20 with no mention of 19.

Serrations are generally straight sided, but your do look to have some curve on the sides, so maybe the involute suggestion is a good one.

The standard method of measurement is with two pins in the grooves and a dimension taken across them, but again with an odd number this does not make life easy. All the one listed in the BS are even numbered.

Sorry I cannot be of more help.

I already have a set up for doing Four Facet drills on my Union T&C grinder. I use DA collets on that rig up.

Phil

I wonder if one of those would be any good for holding drills for sharpening on a T&C grinder with a bit of modification.

If the back end was made so a drill could pass right through and assuming those vee jaws would grip the drill flutes accurately ?

Just my 2p worth.

Phil

P.S. I have just read Clive's reply two posts up.

One thing I have used the Foliac flakes for is to make a spring lubricant. The rear springs on my Morris Traveller were knackered so I treated it to a set of new ones last year, the new ones were not lubricated at all when they arrived and had barely any paint on them either.

I made my own concoction using Waxoyl and Foliac flakes mixed 50/50 and after stripping the springs I re-painted between each leaf with this stuff. Then re-assembled them and lathered a bit more on for good luck.

I have to say it works wonders, the springs are rust free and working very smoothly still, as it seems to stay put way better than any grease would.

Phil

Is the Foliac mentioned above in a paste or flakes form ?

I have a few tins of different but fine grades of the flakes type, and I was wondering if that would be suitable for this job. Or is it different stuff altogether. ?

It came from my late father's workshop when he died, and would have been used on our full size traction engines.

Phil

While we are on lock down I am doing some preventative maintenance on mine. Strangely enough my late dad used to run 1930's Rolls Royces whens nobody wanted them in the late 50's early 60's.

He sold the last one a Phantom 2 in 1964 to buy a roller, but this time it was an Aveling & Porter steam roller.

Happy days

I have just pulled the outer sill covers off my Traveller this morning with some trepidation and dread of what I might find under there. I was pleasantly surprised to find the sills are in tip top condition and there is lots of dried up old waxoil in there still.

So I am just about to set to and scrape it all clean again,and then inject it all with some Dynax S50 instead.

Phil

That's how I got mine as well, the set was included with my Harrison L5A when I bought it.

NDIY

What's your dislike of "Moggie Minors" all about ?, they are OK if you look after them and maintain them properly.

Phil

Yes it is a ratchet hob, they only cut a very small range of tooth counts to the correct profile.

You will see that the face of the cutting profile is slightly convex, but when the hob is in action the ratchet tooth is produced by a rolling action and so ends up flat when used for the correct tooth count.

I have some of these type of hobs for my Mikron 112 hobber, they are not always marked with the tooth count and a bit of trial and error is need to establish what you can use them for.

To be honest for most of the ratchets I have made for my musical boxes and clocks, I still do them by the good old one tooth at a time method, but if you have a need for a large quantity of one particular size then hobbing is the way to go.

Phil

I use the Burnerd Multisize ones, you have to keep them clean and well lubricated otherwise the blades get stuck in the slots and the collet struggles to self eject from the taper and release the work piece.

Other than that I find them to be very good for general use, and the collet chuck lives permanently on the lathe, it only comes off when the four jaw chuck or face plate is used.

I cannot comment on the Crawford Multibore ones as I have never used them, but they work on a different principle being rubber sprung segments rather than sliding blades.

Phil

Which part of Yorkshire are you in Mark ?

I used to build and ride pre-65 trials bikes, I have a 1972 Honda XL250 and a 1950 BSA Gold Star on the road now.

Phil (Silsden)

Mine has separate support collars under both the head and the table. Maybe yours did when it was new.

I have a floor standing version, maybe the bench model was different, I would like to get hold of a rack feed table for mine, but they seem to be like hens teeth.

Phil

PS

I am guessing yours is the one that ended 6th April on ebay ?

Hi

I upgraded from a cheap Chinese pillar drill to a Boxford PD8 last year,.

I am really pleased with mine especially as it has a three phase motor running from a single phase inverter, the speed range is amazing and I never need to change the belt position on the stepped pulleys, the normal range along with the back geared range gives everything I need.

The Chinese one always felt "cheap and nasty" and I never did get on with it, but the Boxford is a delight to use.

Do you need an instruction manual / spares list ?......PM me your email address if you do.

Phil

I am just wondering if the surface contact area between a wheel tooth and a roller would be sufficient to overcome the friction between the roller and its pin, so that it will revolve if you see what I mean.

It would be an interesting experiment to prove it either way though.

Phil

Are they for pipe threading ?

Phil

On my Putra 1770 I have two tailstocks available, the lever feed one takes standard 10mm Pultra collets the same as the headstock, but the screw feed tailstock takes the short version of the MT0. So they obviously used both in different situations.

I have never come across the setup in the original post before, I think it must be a one off.

I somehow doubt it, but its possibly worth asking Myford if they know the answer.

Its not very good engineering practice to use the same part number for a changed part if it is not "Fit Form & Function" though.

Sorry I cannot be of more help.
