Problems with planer thicknesser

[dave323]

Planer thicknesser is not pulling wood through very well. Its a second hand Elu EPT 1161. It was working better when I got it to start with but its now struggleing with like .5mm shavings. The blades are quite new. I have tried adjusting tention lever but it does not solve the issue. Its a drive pulley system, I have taken a pic so you can see the workings. The 2 cogs with the chain on are attached to round pins which feed the wood through. The machine seems to not have enogh go to pull the wood through. Any ideas why or any suggestions anyone?

Many thanks

Check the drive belt. :?:

Hi

Have you checked for deposits on the drive rollers?

Have you tried putting polish on the bed? I think you may find it is the bed that is not clean. A little wax on the bed should work a treat. I have the same machine and do this each time I use it. when the bed has a build up of resin and such it gives the impression that the rollers are slipping or it hasn't got the grunt to pull the wood through. Give it a good waxing and all should be well again. HTH. :wink:

the belts all seem in order, I can't see any broken and the go round fine.

There is quite a lot of wear on the rubber of the rollers there may even be patches missing, I will have a closer inspection of this. I had noticed it before but had not given it proper consideration that it could be the cause.

Perhaps its important, when you try to set cut 1mm or more it makes a loud repeated, scrunching noise like kank kank kank kank. Followed by my cries stop!!

I will try waxing the bed also. what wax do you use mailee? I tried some beeswax on a wooden router table (which was fine before) and it just made it really sticky. I guess its just for metal or the wrong stuff.

I use the Liberon lubricating wax on the all of the table/beds of my machines, it makes a world of difference and on cast iron also helps stop the dreaded rust.

Yup, what Dave said. :wink:

Hi,

I had this problem with my planer thicknesser, a Elektra Beckum 260. It was down to the tension of the spring that tensions the chain. A quick repair later and it was as good as new. Hope this helps.javascript:emoticon('')

just to confirm what others have said , clean beds really well and the rollers, little wax on the bed or a spray polish if you like, I had a jet thicknesser that made a kluk kluk kluk sound and the timber would stop or slow, turned out to be the drive chain lose so it was jumping on the teeth!! had to take a link out to fix it...

Thanks all for your replys. Yes indeed it was the bed, I gave it a good clean and wax and its pulling through fine. I even did a 3mm cut
I had not realised it was such an important factor. I know to keep the bed clean now!! I will invest in some liberon wax too, I don't think the stuff I have is for purpose.

Glad to hear it worked. :wink:

another fan of Liberon here, great stuff use it on all my machines now, especially the CI makes a world of difference on the PT.

If your wax is turning 'sticky' then it sounds like you're either applying too much or just not giving it a good enough buffing.

I'm also a fan of the Liberon wax although, I'll admit to using dry PTFE spray more often because it's a lot quicker and easier (particularly when working with resinous softwoods). :wink:
