HELP Wanted! Cutting Metal – But By What Means?

[Ian S CParticipant @iansc]

Hi jason had a look at Westbury’s saw,I’d have 2 complaints about it (1)short blade.(2) castings.The design could be adapted for fabricated assembly,and in that case the frame could be made any size you like.Just as an aside,I’v got a little power hacksaw with a junior hacksaw blade that I run on one of my hot air engines,It does take 15-20 min to cut a 10mm steel bar.Ian S C

But the beauty of a power Hacksaw is that you don’t NEED to stand and watch it.

IanSC, thanks for that, think I understand you, will get the little drg. board out soon,seems doable with my equipment, am I right in thinking the main criteria is to get both conrods the same centers?

[Ian S CParticipant @iansc]

Hi Gordon The con rods Are vertical and pivoted at the corners of the frame,so about 300mm apart,they could have been 4″ long.The frame was 5-6″ deep and as I had some was made of 1 1/4″ square steel.Never having used an electric welder I went out and bought one and used the saw as a do it yourself learning process,all welds hung together!You could make the frame from any number of steel sections.if lighter you just add more weight.ou can make legs or sit it on a box or bench,legs make it so you can hang the motor underneath.Ian S C

Iansc, thanks for that, just to get my head clear,(just back from dentist) The hacksaw frame hangs on two “con rods” which are hanging from a horizontal bar. The h/saw frame is driven from a conrod/crankpin? Is it just gravity that keeps it cutting vertically? It all sounds to easy. As I am now skint, see above, might be next job.

[Ian S CParticipant @iansc]

Yep you got it Gordon,I was,still am skint also,so my saw cost only time and $NZ10 for an industrial hacksaw blade,about the same as a blade for one of the small H/V bandsaws.Yes the frame is driven by a conrod.The bearings used were heavy duty with 1/2″ bore,there was very little side play.Ian s c

[Gordon WParticipant @gordonw]

Thanks for all that Iansc, more or less “designed” one while at dentist, clears mind. Will use std. blades since had a box full given, also two hanging rods each side of horizontal bar, should be stiffer, thanks again.

[Ian S CParticipant @iansc]

Sounds like its the dentist whos keeping you skint!Ian S C

[Ian S CParticipant @iansc]

Sound as tho the dentist is the one keeping you skint,or is dental work on the national health?Ian S C

[Gordon WParticipant @gordonw]

Right first time, but I am old enough to remember when it was on NH. Latest quote is more than a small eastern lathe.
