Project auto cut off hacksaw

[Noods]

made this little project, built for accuracy rather than speed, I can set it cutting, including angles, and leave it, safe in the knowledge as soon as it’s complete the switch cuts the power off...

Hope you like..

That looks well made mate.
Some posh parts doing the business there.

That’s ace

Beats using a hand-raulic one. I was earlier and was sweating like a bull.

A good recycling and re purposing project.
Be interesting to see how the bearing on the limit switch holds up long time.

Tidy job.

Did you consider a couple of oilers on the sliding rails?

Yep... fair point mte.. I got them direct fro China and bought spare bearings at the same time for next to nothing... cut two inch thick solid steel the other day no issues, took 30 mins but a beautiful square cut and finish.. ( while I had tea and bits) will post pic of it later.. the plastic wheel just runs with the blade and hardly gets a groove on it tbf.. the vertical guides adjustable for play and doubles up as a rest for the hacksaw when I place a new piece in the vice.. the supplementary work support is level ( bang on ) to the vice, this really seems to help... very good too at lobster angle cuts on SS tube, even though I ain’t any good at welding SS .... yes still Richard... x

Where do you mean exactly? I was going to put a drip drip one over the workpiece but I just squirt lube at it now and then..

Stroke seems a little on the short side. Why is it set like that?

On the bearing housing the rails run through.
Designed for minimal sliding by hand so worth considering given the constant sliding there now subject too.

Yep... it’s well greased but I might add an oiler I think.. x

Yes at mo it’s using 1/3 of blade I’d like a little more but the two rear sliders won’t go a great deal further so it’s a bit of a trade off.. o have made the vice so it can slide forward and backward, it’s on slots with pinch bolts so I can play around a bit to get more use out of the blade...

Unfortunately previous owner had dumped this old evo outside so even though I cleaned the linear bearings out best I could and greased them up there’s still an element of rusty grease about it...

stick a dab of oil on them when in use rather than grease I just oil my rapidor slides now and then

Like that a lot, it’s great. Do you grind the teeth off the blade where the stop roller contacts?

No mte all’s good there.. the only thing I found was I had some cheapish screwfix blades, tried one and that was poor, replaced it with an eclipse and brilliant... x
