    Need to make one of these, looks like it could be useful at times where there is little access that a magnet cannot be used.

    I also should learn to braze, never attempted it before.

    Default BS5S Bandsaw mods & tooling

    I have owned my BS5S band saw for a few years now and have all ways felt that the 8mm bearings on the four blade control fittings could be wider, so I turned up a new set, two straight and two off set to suit 10 mm wide bearings. You can see in the pictures that the extra 2mm of width fits nicely on the blade. This extra width should also eliminate the blade cupping.Another area I wanted to improve was the down feed control rate. If you need to cut an occasional piece of RHS section it would be nice to achieve a straight square cut with the current 10/14 tooth blade rather than swapping it out to an 18 TPI one. I made up the spring button and tool that allows for a quick installation for a temporary increase the spring tension. With this fitted my control on the hydraulic down feed has improved a lot and straight square cuts on RHS are easy.I also fitted a large drip tray to keep oil off my floor.
    After reading Anorak Bobs and others posts on using CCMT and other small inserts it reminded me of a post by Stefan Gotteswinter that I had read a few years ago. I had this on my "to do" list but had forgotten it, thanks to BT Bob for the memory jog. I made up an insert tool and a lathe tool holder, just waiting on some 2.5mm taps to arrive to finish it off and try it out. As we all know it is almost impossible to have too many tool holders, but by looking at my tool tray I must be getting close.
    Yesterday a mate of mine needed some 16 TPI UNF threads cut on two pieces of 3/4" bar. I cut these on the lathe using my air/oil mister system and it worked out real good as you can adjust both air and oil independently with just the right amount of air to keep the tooling swarf free. I hope Alf has sorted out his lathe threading problem, being able to cut threads is a great use of a lathe.

    That's quite an assortment of tool holders you have there.

    Do you have any more info on your hydraulic down feed setup? What sort of valve is that and are you just using pneumatic tubing and a standard air cylinder?

    I think I posted some time ago about the down feed control set up, I know I made it up out of some left over parts I had on hand. The flow control valve was an old hydraulic one I had that used to be on one of my tractors. The rest of it I made up to suit it is hard to find a standard cylinder to fit in the tight space. I will have a dig around in my computer and see if I can find it.

    I could not quickly locate the post on the build, I did find a set of photos that should show you the build details.

    Thanks for the details photos, I didn't release you made the cylinder as well, I thought it was an off the shelf item when you posted the previous photos. You did a good job with it.

    I had a bit more time this morning and found my original post. It was "Your latest project" post #934-#938. Could be of interest if you wanted to build one yourself. Thanks for your interest.

    A bit of a trivial one but I got a chance to use the mill which made things a lot easier.

    The issue was the mitre slide on my 12 year old budget level table saw was on the sloppy side.

    So I turned up a couple of 16 mm diam x 3mm thick PB discs with 3mm holes drilled 0.5mm of centre.
    The offset allows for the discs to be rotated to snug the mitre slide up against the other side of the mitre slide slot.

    The funny looking piece of metal in the picture is the screw driver use to rotate and hold the disc while locking down the screw.

    As the screw hole is offset by 0.5mm, when the contact point wears the PB washer can be rotated to a new pressure point

    I had a visit from the FUF (F-up-fairy) and initially drilled the flat bottomed recesses on the wrong side of the slide.
    I though I could just turn the slide over but couldn't do it because of the countersinks for the screw holes in the slide used to attach the mitre etc.
    However, I turned that to some use as this meant I could then add a locking nut to the other side.

    I made a simple turntable for welding using wiper motor and the old car's wheel bearing I have but not yet putting it into test....

    Jackaroo, that's really neat. What did you use for the bearing carrier? Is that from a car as well?

    Graham.

    Hi r3292c, and welcome to our forum. Thank you for posting your work, very challenging to make I'm sure, and lots of opportunity for the "stuff up fairy" to intervene and ruin the job. intense concentration and attention to detail for extended time periods being just two of the requirements for success, and I'm sure that you could come up with plenty of other factors needed as well.
    Congratulations on your success, and if you wish to do a bit of a write up on just how you went about this exercise, i think that you would have plenty of interest from this forums members. Cheers,
    Rob.

    Hello Rob,
    Thanks for welcoming. And you're right. Making these cubes on a manual machine requires "concentration and attention to detail for extended time periods"... However, I was able to overcome these requirements by building a CNC lathe . It also reduces the probability of human mistake a lot!

    I had considered that your project would be a good candidate for CNC, but assumed that you had done it manually. Looks like you have another good opportunity for a good write up.
