Ok Update in the Felder Bandsaw issues.
After approaching Felder UK (not Felder but importer) and giving my concern regarding the blade wobble, they asked Felder Austria if they can sort the wheels out under warranty. Apparently Felder declined as I was one month (or just under) out of warranty.
But! Felder UK took it upon themselves to try and fix the issue instead and so sent a technician round.
The tech agreed with me that the wheels weren’t.. well.. very round and that the blade was drifting from side to side because of high and low spots on the wheel.
The mad thing is, the differential between the high and low spots was only about 0.4mm, which would seem like nothing but; had quite a drastic effect.
Felder Replaced the top wheel with one that had a high to low dif of 0.2mm, which is a huge improvement. Is it acceptable? I don’t know but I think it's pretty good. Worst case scenario, the new wheel could have been even worse! What was immediately noticeable, was that the casting of the new wheel, was much better than the original wheel.
Now Jon (I think it's without the H) at Felder, had said there would be no need to replace the bottom wheel, as the top one has the most ‘influence’ on the blade but; I couldn't quite follow the logic. I told him that although there had been an improvement with the wheel, the outcome for the blade was no different as the bottom wheel had the same differentials.
He then agreed and said they would change the bottom one too. I had told him when they were doing the top wheel, to do both for the sake of efficiency but; I can see that it is perhaps more prudent to see if the issue clears up, before they invest in two wheels.
So the second wheel came and was fitted and the dif between high and low was again reduced down to 0.2mm and actually, on the bottom wheel, that dif is caused by the join in the tyre.
So yes the blade still has a slight wobble but it's much better than before (is it 100% better, 0.4mm to 0.2mm?) and I don’t think they can do much better, given that when you put a dial on 0.2mm, even a bit of dust will cause some variation. Leaning on the machine causes more of a variation.
I’d like to commend Felder here for their work. The fist tech who replaced the top wheel was a bit green, young lad but really friendly. I helped him a bit and it took him about 3-4 hours to change the wheel
The second tech is one I've met before. He’s their top guy and he changed that bottom wheel in like 30 mins or less. Really nice bloke, a smart thinker and interesting to talk to.
Felder UK stood by me, as a person new to wood working. Even though the bandsaw was 1 month out of warranty, I’d only used it a handful of times and hadn’t even been able to set the thing up for several months, after it being delivered. I told them I couldn’t really know what was right or wrong as I had no experience but as I gained experience, I could understand if something wasn't quite right.
They agreed and stood by me and so I’m happy to be a customer. They seem much more customer focused than they did even 2-3 years ago. They've certainly improved their systems. If was a bit of a mess before.
Regarding the experiance, yes there were down sides. I spent about 3 weeks having to take a crash corse in bandsaws because this one had an issue. It cost me a lot of time and stress. I had to spend hours trying to work out how it worked, watching videos. I bought a dial and base to clock the wheel etc..
But! in a way I’m glad I had to go through that. I learnt a lot about bandsaw in a very short space of time. I learned a lot about how to test machines using dials etc.. and I learnt who my friends were. It turns out that Felder UK is one of them (although perhaps not Felder themselves)
Onwards and Upwards!
As an aside, I've come to the suspicion that the bandsaw is made by ACM in Italy. Felder claime to make it but no tech has ever seen the ‘bandsaw manufacturing line’ at Felder Austria and ACM pretty much make all the bandsaw sold in the EU for under £6K.
