Boxford Shaper Vertical feed

A different query this time for the Boxford Shaper.
Does anybody have one with the vertical feed option please; mine is horizontal only.
I was intending to purchase the two parts needed to add the facility to mine, a ratchet wheel and drive gear, but alas Boxford are out of stock.
They were also unable to provide any diagrams, as apparently they were lost in a fire some time ago.
I'm after a tooth count, thickness, and diameter of the vertical ratchet wheel, and the drive gear which sits adjacent and is pinned to it.

Many Thanks
Bill

I think that you only need two gears and piece of shaft to match dia of other two shafts.

I have the vertical feed on mine. Will take some measurements tomorrow, unless some else beats me to it.

Barry

hope the pics tell the story, the gear with a plain section is moved from cross shaft to vertical shaft using the same rachet mech to operate both.

Please could you clarify if the picture is of a Boxford shaper. If so, it differs to both the mark I and mark II versions shown at lathes.co.uk.

I think you'll find that most English shapers were made in the same factory and badged.

Thanks for the reply. Your observation is noted, but it does not answer the request. Would you kindly confirm or not that the pictures are of a Boxford.

The feed mechanism looks nothing like my Mk2 Boxford.

Thanks Barry, that looks the same as mine, barring the colour; mine is blue as per the photo(s) on Tony's site.
The lower gear on the vertical feed shaft, obscured from view in your photo, is present; I'm missing the left hand gear and the ratchet wheel in the centre from the upper shaft.

The Boxford Spares site is handy, in that it includes copies of the original blueprints.

I'm short on items 8&9.

I appreciate that the ratchet wheel will be the same diameter as the one I already have, but the number of notches may be different, to get the correct feed rate for the vertical drive chain; it's hard to tell from the diagram but it looks like your photo shows it as about the same.
Next one is the number of teeth on the left hand drive wheel.

Cheers
Bill

I think Bernard's machine might be an Elliott/Alba, as the ratchet mechanism looks similar, and the ways are rectangular, rather than the dovetails on the Boxford.

Bill

Have just had a look at mine.

The two ratchet wheels are identical, size and tooth count.

The gear on the left is 26 tooth and 1.4 inches dia., so that makes it 20DP gear.

And almost certainly 14.5 PA

Thanks Barry, much appreciated.> I think that makes it a standard Myford gear, cheap enough not to need to try making it; maybe just need to change the bore size.
A little project for when the nights start drawing in, and I'm awaiting the return of some Ducati bits.

Thanks again for your assistance on that one.
I went to order a 26 tooth gear from RDG, and found they had some dirty ones going cheap, so not worth me buying a gear cutter for the one job.
It fits and meshes nicely.
Fortunately I had a lump of 50mm EN8 in stock, so made up a duplicate 40 tooth ratchet wheel, and the machine now has vertical feed.

Dividing head set up on the Centec, showing the riser block in use for horizontal milling.

Seems to work well enough, and convenient at 40 tooth so no holes to count.



The completed assembly; the bit of bar was just for lining things up.

There's a few more photos in the album.

Rusty gear ordered from RDG.

Have you got a link for the gear as all I could find was a 26T Myford change gear unless this is what is being referred to?

Thanks, Craig

is the one I have bought Craig. It is a Myford change gear.

Perhaps peak4 could confirm this what he used - but there cannot be many "shop soiled" 26 tooth gears suitable for a Myford sold by RDG on Ebay.

Nigel B

Yes, a Myford change gear; sorry. I intended to mention it in the post; I did when posting the photos on Flickr & Faceache.

I'm just doing one, the tricky bit is cutting 40 x 1/16" grooves in the ratchet, you really need a shaper for that.

I broke my only 1/16" end mill and had to do them 2mm.

The gear is the same as the one it meshes with. I gave it a sintered bronze bushing.

It goes up and down like anything. The vertical drive shaft has a steel gear taper pinned on the end. Be sure to remove the bronze gear behind before knocking the pin out. Angst

Have you found a supplier for 3/32" x 1 1/2" taper pins? I got some 1" from EKP but I need bigger.

Robin

Thanks both, have now found it and ordered one
