Cool.??
You might want to increase its size a bit and make a mini-vertical-table so that you don't need to take it off to replace with the vertical table. There are pictures in the Photos section for them that can be left on when the saw is used horizontally and are instantly ready for vertical use.? Not big, but enough for most jobs. Only thing I can think of which might be a problem (and it is how ever you make any scraper) - check that the top surface of the guide roller block is square to the blade - often they're not - jv |

Ok, I have a couple of ideas about the design. One design would be printed similar to the aluminum piece that you use to carry the hacksaw blade scraper. I envision making the angled blade carrier (the area that the scraper blade is attached to) somewhat larger for more support from the plastic and slotted such that the blade could be sandwiched between two sides. I would then use an appropriately sized screw through the hole in the blade and press-fit a nut in an inset on the blade side to clamp the blade in place.?
The other idea would be to just print the whole thing and do away with the blade altogether...alternatively, slot it as above so that a replaceable wiper blade made of one or more thicknesses of plastic cut from a milk jug could be used. As for the vertical seat/table, I like the hinged design that is in the Sept/Oct 1997 HSM magazine. A picture of it is in the files or photos section...I have that particular issue so not sure where it is here. When you refer to the top surface of the guide roller block being square to the blade, that is something I hadn't considered! Are you are referring to the surface of the guide roller block that the scraper attaches to, so that if it is not perpendicular to the top of the blade the scraper blades will be skewed and could hit the teeth of the blade? |

To tackle your questions in reverse order:
1. You've got it, about the top of the guide roller block needing to be square to the blade at least in front elevation for the scraper to work correctly. File off, turn by holding in the lathe independent 4-jaw or shim are ways to correct.? 2. You can use any design for vertical table that appeals to you.? I used the small angled-shape table as an example because it would be easy to incorporate into the scraper block design than the flip up one but do as you please.? At the moment I have to dismount the scraper to bolt on the vertical table so combining the 2 has real-world advantages 3. I thought you did mean printing the scraper blades as one with the body and can see no real reason not to? other than longevity,? PET doesn't have the same abrasion resistance as UHMWPE, but that said it might well last long enough. HSS hacksaw blade ends obviously would last longer than any plastic wiper/scraper and I like the idea of slots for them to fit into.? The only trouble I had in making the aluminium version was tapping the threads for the fixing screws, had to grind off the bottom of the tap, so the threads would go in far enough - there's not much room for the end of the tap with the threads angled to one another.? Maybe you could print the threads? (- only just thought of that and don't even know if its possible???) I'm trying to envisage the press fit of the nuts but there really is very little room to slide 2 nuts in the back of the blade holder Give it a go! - jv ? |
开云体育If you guys are interested I posted a picture several years ago of some
simple sweeps I came up with for my saw. They only consist of two 90 degree
braces with stick-on felt from Lowes. They are held in place with small Neodymium
magnets which makes it very easy to remove, clean or readjust. There are also a
few other pics of some other simple mods to ease use of the saw. They are in the
album Carl’s 4x6 at the group.

Just out of curiosity.... Could you drill holes in a hacksaw blade and incorporate the blade in the printing process? (Think plug welds).? For the record, I know very little about 3d printing.? Darren

开云体育De nada Carl, ? Yahoo takes a little navigation to find albums & files, as someone pointed out to me a while ago. Since, I try and make it easy, and I went in search of to see your pics, easy enough to through the link out there. J Bill ? ? From: 4x6bandsaw@... [mailto:4x6bandsaw@...]
