Hand shaper

Hello All. All the best for 2018.

Does anyone have any opinions/advice on the hand shaper featured in the recent Model Engineer special? I am looking at buying the electronic comic but also have my eye on a couple of the other editions.

Cheers

Looks like it needs a bump or nobody has any experience!

I have not seen a pic or any other detail of this one, but if it works as well as a Drummond it will be good. I also like my Alexander as it provides a superb finish on aluminium, even without its autofeed bits (although it would be far easier to operate with an automatic cross feed).

If this is a build project an autofeed system really needs to be included, to make operation more of a continuous nature as I find manually altering the cross feed every stroke makes getting into a rhythm, with the cutting stroke, a bit awkward or slow.

Do you mean the Adept Number 2 in Bill Morris' article?

I have one, it's come in handy for a couple of otherwise difficult jobs, but its a slow and steady machine not a racehorse.

Honestly 'slow' is a bit fast for describing a shaper.

I have a Boxford 8", and it's very therapeutic in the way it has all sorts of spurious motions. I can watch it for hours. Which is just as well because I need to to see a job through with it.

OK, if it is the Adept. Here are a few pointers .

If it has a manual feed, a finer thread would most certainly be better. The Drummond has an 8 tpi feed screw and it is a pain to advance it in sufficiently small increments while being consistent in size of cut. My Alexander has a thread pitch of less than a third of that.

As in my first reply, an auto crossfeed would be a great improvement. I’ve started on the parts for my Drummond, but other things have got in the way over the Christmas period. I will get to use it properly when sorted and be able to compare the machines (OK, the Drummond will win).

One of the gib adjusters on the cutter height adjuster would be better changed for a locking screw - to reduce any movement/backlash in the mechanism wihie operating.

With T-slots, for table height adjustment, it is fiddly to have to set the table level every time it is altered.

They operate better with the cutting edge further back, than in the lathesdotco pics. The proper cutters had a crank in them. Not sure of the proper term for them. Operating with the cutter as short as practicable is good (just look at the tool extension length on some pics!).

Cutters are single point, so far cheaper than end mills for a milling machine. But you do need a means of sharpening the cutter to a razor sharp edge - and to keep it like that.

Apart from being slow, they are a good machine for getting really flat surfaces and useful for other jobs which might be awkward with a milling machine, or it might avoid breaking down a set up on the mill.  Definitely good for internal keyways.

Those without a shaper (of any form) will often say they are simply not needed, but those with them usually would not wish to divest themselves of their machine unless almost forced to.

Hope that helps. I like shapers - even hand powered ones.

Manual feed on my adept, but about 16tpi. An auto feed ratchet would be the one thing to add.

The notes say it is 'FT Leightfords'. It said it was built from rolled sections.

People always say shapers are slow, but they should see my 18 inch Alba taking a quarter of an inch off in a single pass.. Ok, you are not going to do that on a hand operated Adept, but even that will be faster than the same guy pushing a file, which would often be the alternative.

Actually the rate of metal removal is mostly a function of the horsepower, Isn't it supposed to be a cubic inch per minute per horsepower? A horizontal mill will remove a lot of metal in a single pass, but requires a correspondingly powerful motor to do it, as well as an expensive wide cutter.. But anyway, for amateur work speed is not usually all that important.

They do have many uses - cutting splines is one , i use mine to cut the lines on dials .

Can you give us the issue number and date?

Best of Model Engineer Vol.3. The cover has a Lynx OHC engine.

Well I took a chance and purchased the digital magazine. What a disappointment. 80 of a hundred pages devoted to the IC engine on the cover and a steam loco. The shaper is a 3 page reprint from the 40's.

Pocket mags needs to put the first page of every article in its preview. They had too many pages of the engine build for this issue.

Once bitten twice shy. Unless I see the article I am interested in, I won't be buying.

An Adept (2, I think), which looked to be in good condition, went for a mere £250 on epay this last couple of days. I would not personally pay that much for one but, clearly, someone wanted it (unless it is relished...).

IMO Hand shapers like unimats command a good price because they can be sent in the post

Even allowing for buying a new angle plate selling mine for that would give a 500% ROI...

I think I'll keep it though

I love shapers, but:

Had an older Drummond hand shaper; it ended up being sold to a fellow club member, who in turn sold it to someone in another area of Ontario.

Beautiful machine. But, in the time I had it, it scribed exactly 3 lines, for something resembling a graduated dial.

It took up a lot of workspace. A piece of artwork, but, I don't own a machine-tool art gallery.

Years ago I had an AAMCO 7" powered shaper, which again was great, but it was slow, chips went all over the workshop, and one could not do what a vertical milling machine could do. Sold it when I moved to NZ for a bit.

Would I purchase another shaper? You bet! Have my eyes on one if I can clear out the workshop some more; would I use it though? Hmmm...
