Clarke CBS45MD 6x4 Metal Cutting Bandsaw Modifications

[Richard.]

After fitting a new razor sharp Starret blade twenty minutes earlier the works machine has stripped the worm and gear

Not great timing as tomorrow (Wednesday) there's about 50 lengths of 50mm box coming and a lot of 80mm to make into things fairly quickly. Anybody know where to get the bits? I've sent a parts enquiry to Clarke as they'll probably be the same as this 1987 machine but otherwise I'm struggling. Any suggestions?

I dont think the worm and gear has changed at all from a design POV from the very old ones to the newer ones. My old 6x4 is from the 70’s and the worm drive was worn out. I bought a scrap seally for next to nothing and just swapped the bow over and put all the better made monarc saw parts on it. The worm and gear drives were identical. It will probably be cheaper to buy a banger with a good drive and swap bits about.

Finding a banger (never mind quickly) is much easier said than done.
The saw actually cost nowt and runs (well, ran) perfectly, lovely thing. Bit of a nasty surprise when this bit packed up, though I think it's a known weak point.
I don't want to have to rob my saw to try and get the works one running faster...

Ring clarke up, there actually quite good for spares, youll be surprised.

Slap this in the watch list. It’s always handy to have spares.

@Richard. What type of adjustable steering damper did you use for your saw? There are several types listed on ebay, was it something like this?

My saw is cutting off square vertically, in towards the vice. I've tried a new blade & all manner of adjustments & I can't sort it. I remembered one of your posts about your damper mod helping this so I tried supporting the bow as it was cutting - problem solved! So I need to fit a damper, not sure how as this saw is the type where the whole bow pivots to cut angles!

Trouble is, it's not exactly local!

It’s a generic universal Chinese damper. The only important thing is getting one with enough stroke to give you the lift you need.

Ha it makes me laugh. It’s just over 100 miles for you. It’s not exactly far.
People on here miss out on so many great deals across the country because it’s not on there door step. If I was in your shoes I’d be prepared to have a bid on that and if I won I’d have enough spares to keep my saw going for many years. That’s me though. I’ll drive to get the bargain.

My first thoughts are too much weight on the cut and/or blunt blade. Which saw do you have, any photos?

Go to a Machine Mart , ask for a catalogue there is a spare parts telephone service for your needs.usually on the index page or the one that gives store information . Saves several days if you pay for the courier service

From recent experience the parts staff i have spoken to only deal with part numbers and prices, but have no product knowledge as to when parts have changed throughout a product's life.

Ditto, no problem driving to get stuff, my M300 was in Crewe so defo not local to South Wales, nice day out to go and pick it up

Me too. Ive had a good few AC/DC tig sets. Some of them have been a full day out. I drive a diesel and go steady away. I can get to most parts of the country and back on less than a tank of juice.

 

[indy4x]

Wish I could in the D2, 28mpg normally but on the Crewe trip I was towing a 3.5T Ivor Williams so a little less, probably 26ish tank holds 95l so will do over 500m on a fill

 

[Richard.]

Yeah I’m getting a little more than that. 60mpg is about her motorway average at 70-75.
Mind you I don’t tow with it. If it doesn’t fit in the boot i borrow a van.

It's a sealey SM65 saw.

I've tried a new blade & adjusted it every way & it makes no difference. It has no proper adjustment for weight on the bow, hence the idea of adding a damper.

Looking at the parts diagram there should be a tension spring on the bow pivot, is that broken or weak? That would add extra extra weight causing the blade to wander under load.

Err, 250 mile round trip according to eBay and google...
I will let you suggest to the boss that he pays me to go collect it! Plus my car is running on a blown HG...

Sometimes things do need to be local.

I took the bow off mine (can't easily move the base) to temporarily put onto his, but the pivot pins are actually different. Then tried swapping the gears to find that the worm shaft is also different. All great fun

Thanks, will see what I can do. I have contacted Clarke through their online parts site and received no reply, which is very annoying. Will try more methods.
