The DIY Bandsaw..
NeoTech:
So basicly, i'm gonna try my hands building the bandsaw design i linked in my "Neat stuff" post..
Goals, compact 60cm throated metall cutting bandsaw, 3 speed.
Some valid questions came up there and i think they should be sorted.
Discussion points:
Drive wheels - size.
Traditionally it seems bandsaws uses large wheels for turning the band. And the design i found didnt. Further investigation into this subject shows that the large radius wheels is mainly to reduce stress in the band itself when its running fast. If running slower speed and thinner blades, the drive wheels size can be reduced. the price you pay is versatility.
Drive wheel material.
For a larger drive wheel you could make something out of strips of steel. If you have a roller. - i dont. So for large wheels i would have to resort to wood.. or mdf.. it still a hassle to get that perfectly round but a makeshift wood lathe could be conjoured up i guess.
Otherwise is the use of urethane casters. they are available from 100mm to 300mm and have a solid urethane gripping surface for the sawblade..
I plan to make it a full steel frame with steel door covers and sheetmetal.. Im guessing it will weigh a bit.. but is it enough..
Saw blades - for economy it seems that silversoldering your own blades is the way to go. Buying roles of half inch blade stock from ebay is dirt cheap compared to the premade ones..
For motor im aiming for a 0.75kw 3phase motor with a VFD.

May I suggest to choose blade length that is standard anyway. You may want to buy commercial ones later on. I just bought two 6 tpi and 6/10 tpi. Most coarse ones I could find. Cost about 25€ a piece, German made I think.

The biggest problem is then.. What is "common" standard sizes.. and how fine toothed could you get em, and in bi-metal versions ..
vtsteam:
Neotech, what about utility metal wheels with rubber tires?
Something like this, maybe:

NeoTech:
Thats actually a good candidate. But then i guess we are aiming for the 4 wheel setup. I guess that could work. :)
