Mystery machine..........

Hi Everyone!

Due to an enforced lay-up (main hydraulic pump fault!) I have not been able to make a start on My workshop conversion yet, but I have been able to check over My Myford Super 7 to look at it's general condition and operation (will do a post this week with a question or two....or three...).

I'm starting to potter around a little as things are slowly returning to normal, and I am concentrating on getting other items in ready for setting up.

The first thing I was looking for was a way of cutting stock up for machining, My sawing arm is not what it was, most power hacksaws are too big for the space I have available, so was thinking off a cut-off machine (Rage etc.) then this appeared on Fleabay this week:-

Hi Pete, sorry no pics here, you better go up to the green line at the top of the page, go along to the camera/albums and start an album, you transfer direct from your computer, best to reduce the size, I use 640 x 480. It took me months to get going, I was on dial up, and trying to put the photos direct without reduction, grrrr. Give it a go.

Hi Ian SC!

Thanks for the tip, I've just created an album with the pics!

I tried to embed them originally from flickr, works (sometimes) on other forums I post to, must have missed something on here!

Cheers, Pete.

Linked pics from album, let's see if this works......

Definitely a power hack saw, probably shop built. With that enormous adjustable weight I bet it could really eat up blades.

Hi John!

First thing I thought when I 'saw' the weight! (Sorry, couldn't resist......)

I did a test cut one some 1" bar, it didn't protest at all, but took a few minutes, stroke rate is roughly 60 per minute.

Started to strip it today, the engineering is exceptional if home built, will post some pics tomorrow,

Cheers, Pete

Yep, looks like a crusty home build, but I bet it works well if you clean it up.

Echoing what John says, I would start with the weight at the pivot end.

Neil

It looks similar to the "Duplex" design in Ian Bradley's "The Amateurs Workshop"

Rod

Hi Neil, thanks for the advice, I will start with the weight further back then experiment with the setting until it is happy!

Hi Rod,yes, the saw frame does look pretty similar to the Duplex with an own designed base and drive system, the further I dig, the more it looks like a shop built machine, very well put together as the photos above show.

(I tried the put the text above the pics, but need to have a play around to get it right!)

Clean up and paint next, thanks for posting these very useful replies, more soon!

Cheers, Pete

Many thanks Rod for the picture of the Duplex Saw. I now know what I have got (ebay buy). I have altered my drive to put the motor underneath the main frame so that when cutting it does not stick out the front of bench.

Morty (Pete) you may find that you need the big weight , I have increased mine and it cuts a lot better than it did.

John

Hi John!

Thanks for the heads-up, I did try it out before I stripped it down,took a while to go through some 1" steel bar, but I put that down to the stroke rate(estimated at 60 strokes per minute, but the gear drive shows 71rpm),but I'll have a proper look when It's back together.

Cheers, Pete

Hi Everyone!

Sorry that it has been a while since I posted on this thread, I did not start back at work full time until January, after recovering from an heart attack last summer,so I have been getting back in the swing of things!!

Having found Myself, like many more, with more time on My hands recentley, I thought it was about time to get on things, so I have finished tidying up My power hacksaw which I bought last year.........

Sorry that the text is in the middle of the photos, i have not sussed out how to layout the posts yet!!

I just need to make an extension for the rear blade peg, I thought that it fit 10" blades,(which I have bought a good stock of...) but on trying to fit a blade, found out it was requires 9" blades??........

The original builder must have shortened and re-drilled his blades to fit.......

Not a problem, saw is stored away for the workshop is finished.

Now, what to do when You are on lockdown?

Ah! I've got a Super 7 lathe that needs a good looking at! (as glimpsed in some of this photos)

Please take care Everyone, keep Yourselves and Your Families safe.

Thanks for looking in, Pete

Morty:

I find it helpful to insert photos using the camera icon between two carriage returns; that way you can always insert text above and below the photo.

Some good progress there Pete. Stay safe stay well.

regards

Looks a nice job now! Well Done!

Any chance of extending (making a new one ) the front frame, so that 12 " blades could be used? 10" seem to be hard to find now.

Howard

Certainly looks nice now Marty. Now I want one.
Before making the rear blade extension look at the movement possible for the vice and which part of the blade is being used. It might be better to extend the front. It only uses part of the blade on smaller items so may put all the wear down the back end and you might want to look at options for reversing the vice and then need more out the front to maximise the space for the vice handle.

Hi there and thanks for looking in!

Ega, thanks for the posting tip, I'll give it a try!

Howard, extending forward would be quite a job due to the tensioning fork, it would mean cutting and modifying the frame, the rear extension would just be a short extension bolted on the existing position. I managed to get a good stock of 10" towards ( 50+) at a good price!!

Bazyle, the base is drilled to move the vice but only towards the crank end, the only way to move it away is to re-drill the vice base and the handle end of the vice would loose some support,if I drill the table to move it I will be into the switch enclosure box.

I will take the suggestions on board and look into them more!

Many thanks! Pete

You are well set up for a while. It should take a long time to wear out 50 blades!

Enjoy the fruits of your work, as you rest your arms!

Howard

Nice one Morty, hope it works as well as it looks.

Neil

Hi!

Howard, I don't think My arms will get much rest, I see much paint stripping and rubbing down in My near future!

Hi Neil, thanks for looking in, it's nice to be back!

Cheers, Pete
