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
