record bs 400 bandsaw

[user 19915]

I have been sent a record bs 400 band saw blade from record as a good will gesture and the first one they sent me was a little slack although they were adamant it was the correct one for my band saw . So they sent me a replacement in exchange for the other one and again it seam to be slack i have tightened the tension up as tight as i could it work,s ok but i don,t like how tight the tension wheel is as anyone else add trouble with the record band saw blades ?? Although i use tuffs blades i have put the record blade on as spare

How far do you have to slacken off the tension adjuster to put a new blade on, at or almost at the bottom of its travel?

This can be a good indication as to sizing of blades in relation to construction or assembly setting of the machine.

I have a BS400 and chucked the supplied blade away without even using it. All mine have come from Ian @ Tuffsaws and they fit a treat.

When changing a blade i slacken the arm right of and release the tension on the wheel With Ian.s blades they fit great but with the record the arm is all the way over and the tension wheel very tight > .. But again i could have over tensioned the spring on the wheel what i will have to do is put the other blade back on from tuffs and see how much i have to tension it open to any suggestions Mock

What I was getting at was that if you only have to lower the wheel part of the way to release and can fit new blade then the blade is more than likely to be overlong for the machine and you have limited tensioning travel left.

If you have to lower it completely before you can get the new blade to fit then you would have maximum travel distance to tension.

You ideally need to air on the latter case rather than the former.

On my BS400 I have to apply tension such that the indicator is at a position for a significantly wider blade than the one I actually have in. My blades are from Ian at Tuffsaws. Not an issue per se and I know the indicator is not meant to be a precision measuring device but I do wnder if I ever put a 3/4" or even bigger blade on whether I would actually be ale to tension it properly. Is there any chance that mass produced saws could have sufficient variation in them to mean that the correct length of blade could actually be very slightly different? I must admit I am thinking that before ordering my next blade(s) from Ian I will call him to see if they could actually be made fractionally shorter to make tensioning easier.

Of course it could be down to my incompetence!

I've just had some blades from ian at tuffsaws. My axminster 350 adjuster was wound so far with the standard blade that the tension spring was fully compressed.
I got Ian to make the blades 6mm shorter, but when they arrived and I measured them they were slightly different sizes from each other.
When i questioned Ian, he explained why, and it should have been obvious to me, but it wasnt, and apparently not to others either.
It depends on the tooth spacing. If your specified mm length happens to fall half way through a tooth, he has to add or subtract enough to make the cut match the other end to be joined.
You cant have a half tooth snagging all the time.

So if you want the blade to be shorter, dont ask for it to be too short.

On my 2616 factory length, I had the new blades made to 2610 minimum. and they work fine.

After i contacted record about the blade this is the reply lol

Thank you for contacting us.
I don't know if we have discussed his before but there is adjustment on this machine for the blade tension. If look behind the top wheel there is a cap head bolt and nut, if you slacken off the nut and adjust the bolt this will allow you to get either more or less tension on the blade. I believe speaking to customer there are few out there struggling to fit Tuff Saws blades on these particular machine, but when ever I have spoken to them if they do as above this will allow you to get the correct tension o the blade.
Please let me know how you get or if you need more help.

That's good news, would expect a decent design to have means of adjusting setting of tensioning mechanism in relation to upper wheel spindle axis but without knowing specific machines it is an unknown, t least we now know a Record 400 has this facility.
