kity 613 bandsaw help please

[user 19915]

help please can you tell my how the fan sits on the spindle ? should it be bolted on or ?? when i start the bandsaw it makes a screeching noise where the plastic fan spins loosely on the shaft of the the motor ?? Also can you still get spares for the saw i notices the person who owned it before my mate was using hard wood as guides top and bottom ? photo's below

Not sure on the fan but hardwood guides were standard at one stage. I switched from beech blocks to lignum vitae as they were much harder wearing and I had some lying around. A spot of glue to hold the fan in place?

yes could well do if it holds tight it will not heat up either

There is no way that Kity ever used hard wood blocks for blade guides on a 613 bandsaw.

I can assure you it's what mine came with from new.

Fans on motors they typically have a grub screw somewhere that you can tighten and that usually fixes it. Have a look for a little hole somewhere between the blades or around the fan somewhere. If all else fails you can always glue it on.

I don't believe spare parts for the old Kity bandsaws are readily available anymore, I've seen a few people ask "Where can I get X for my Kity bandsaw" and come up to no avail. So you might be out of luck for any "Genuine" blade guides. Some people do renovate the old saws with new ball bearing style guides but it really isn't worth the effort on these little machines. I recently renovated a little Elu EBS3601 bandsaw for a friend and made the top and bottom guides up from scratch as the originals had snapped. By the end of it, it ended up costing around £100 even on mates rates. There were £30 of bearings, at least £15 of aluminium, £5 of silver steel, another couple of quid of hardware and a lot of time since everything was hand hacksawed, filed and turned. Really wasn't worth the effort or the money but he insisted very much.

As a matter of fact they did, funnily enough. Cheaper than the Carbon/Mehanite/Tufnol every other bandsaw manufacturer was using and worked just the same.

Mine came with beech blocks as guides. You can make your own blocks but use something more durable than beech. I also had some lignum vitae and made blocks out of that.

I have a Kity 513 and it has wooden blocks.

I was surprised but they seem to work pretty well, it cuts perfectly so I'm leaving it alone.

Stripped and rebuilt a used 613 not very long ago - search my posts for a pic heavy walkthrough of the one I got.
Lower blocks were definitely beech.
The plastic fan on the end of the motor shaft is just a push on - it's a slightly soft plastic and the end of the shaft has fine splines. It's a straight pull off / push on. I didn't realise this when I was first stripping it so I just clamped the shaft and twisted the fan until it gave up and turned despite the splines. It pushed back on when I was done.
If loose, I'd try glue first but a lot of formulas won't adhere to that slightly "slick" plastic. Think gluing milk bottle plastic.
You could try hot melt in the bore to tighten the fit then press the fan on again ?
Otherwise you might be able to drill a fine hole right through and pin with something skinny 1.5mm - 2mm say.

I've never needed to do it myself, but...
My first bandsaw had blocks rather than bearings. I bought some Cool Blocks. Excellent things. But wood was always another option. I read somewhere (don't know where, don't know who, don't know when) of making a batch of wooden blocks and keeping them in a jar of linseed oil. When one pair wore out, dress them true again, and replace them with a new set from the jar. Old set went back in the jar for next time.
Always seemed like a good idea to me.
My BS has bearings so I don't have the pleasure of trying that out.

Thanks' for all the replies ;I have hot glued the fan back already and as suggested i will attempt to put a self tapper in through the fan and into the shaft if it comes away again regarding the wooden blocks as guides they can stay and i can make more when required Alan

Glad you have it sorted.
The blade guides are actually very good as long as you mange them. I liked the idea so much when I bought new guides for an old Wadkin bandsaw I bought some with simple friction side guides.

I can only say again that a Kity 613 never had wood upper blade guides.

"Adjust the small upper hardwood blocks (Q) to 0.5mm on both sides of the blade."

Judging by the fact that this is from the Kity 613 manual, they must've had wooden upper guides.

Must be a forgery :lol:

It's the guides on YOUR 613. It seems to me that Kity have changed the design at some stage and many of us have had the previous version with wooden guides. Whats your explanation?

 

[Trevanion]

Here's one with wooden upper guides.

 

[Sideways]

I recall reading that Kity changed the 613 from the original upper wooden guides to the newer bearing style guides some years into it's life.
These machines have been in production for a fair few years and Kity tended to change model numbers between almost identical machines and change the machines without changing the number.
There was criticism that the newer design was a bit of a bodge, more tempremental and fiddly to adjust compared to the wooden block system but it works well enough for me.

Guess someone doesn't know what he doesn't know

Don't remember where I read this but Kity are French so don't forget to search the French websites when you're reading up or you miss out on some useful pictures...

Is there any chance that those of you who have a 613 with wooden guides could post a picture of the whole machine from the back and the front. A picture of the cover page of the user manual would also help.
