I've had a request from a forum member to make a new handwheel for a Kity 419. He's sent me the knackered wheel:

and a pic of the spindle which it fits:

Because he had the machine second-hand complete with badgered wheel he can't be sure about how it's meant to work. It seems that the handle is bored 12mm to fit the bit on the end of the spindle, and it's secured on that by grub screws - it looks from the second pic that the screws are misplaced and have bitten into the recess (does that have a function?) which can't be right. It's clear that a previous owner has tried to fix the wheel (hence that weird brass bit) but with limited success.

I'm assuming that the recess in the handle bore is there to accommodate the return spring and is necessary. If any kind soul with a working mechanism can help out with more info I'd be grateful. From what I've read failure of the handwheel gear is a common problem with an otherwise solid machine. When it's sorted I'll post a WIP with dimensions if there is any interest.

Bob.

Bob, the pictures aren’t too clear, but working out from the machine there should a be a narrowed section of spindle then lengthwise slots. In use pushing the handle in places the grubscrews in the narrowed section of shaft and the teeth on the knob engage the rack to tilt the blade. Allowing the spring to push the knob out causes the grub screws to enter the slots and so rotates the shaft to move the blade up and down.

I modified mine by adding a threaded rod across the width of the casing and a traveller linking a nut on the rod to the motor housing. I now have the original knob for height adjustment and a handwheel to control the blade angle. It was a relatively simple modification if you have the tools and makes a real improvement to the machine. I think that I posted pics here when I did it.

Regards,

Colin

Thanks for the explanation Colin, that was exactly what I needed to know. I guess what I took to be bruising on the 12mm 'outboard' end of the spindle is in fact one of the slots in which the grubscrews engage. I had wrongly assumed that the wheel was fixed to the spindle so the whole assembly moved, and there would be a gear on the nether end of the spindle which would mesh with the rise mechanism when the spindle was moved out - so I couldn't understand the function of the recessed bit in the spindle. All is now clear. I'm not impressed by the Kity design though!

Your mod looks excellent, but unfortunately the machine is in Wales and I'm in Derbyshire, so for the time being at least it's a replacement handle.

Thanks for the link to the diagram Bod (and to Dibs-h for the correction -I got a 404 from Bod's link) - useful, I'd searched but not found that myself.
Regards, Bob.

Sorry Bob, you did tell me you'd started a thread, but been away working for the last 2 weeks - if you need I can dismantle the handle on my 419 and take photo's etc as mine is in a pretty good "factory fitted" condition.

Thanks for the (unlooked for) testimonial Mock - just glad it works.
For anyone interested, the gear I used was a commercial 12T MOD 2:

It was a bit of a gamble, but it seems to have come off.

Very nice work Bob! It should outlast the saw itself :lol:

I like the idea of putting a standard gear on it, I would've never have thought of that, a very simple work around to some very complex engineering :)
