Hafco T13S rollers not engaging

vendredi 13 février 2015

Hello all :)

This is my first post, woo!

Bare withe as I try and explain what problems I seem to be encountering.

First of all I am just a hobbyist wood worker so I apologise in advance if certain terminology/descriptions are incorrect or unclear.

Alright so I am currently in the process of dressing timber (old hardwood fence palings) to clad my newly built wardrobe with.

To go back to the start of my process I have used a wire brush attachment in my drill to clean every board and then quickly gave it a once over with a belt sander in order to preserve my thicknesser.

So I started with the bright green Ryobi from bunnings and taking only .4mm per pass, this worked fine for around 30 boards. Now the boards are around 90mm x 1500mm x 12mm when I start and I need to get them to around 6 mm thick. After a while I noticed the boards would stall in certain spots and I would have to gently 'help' the boards through the machine and little skid marks from the rollers were present on the timber. After a while that level of 'help' had increased and at times the board would come out with a little pile of roller rubber on it, or I would have to app the machine as it was jammed.

I returned that machine back to bunnings and swapped it for another green machine. Not long into my new Ryobi the same problem was present so I returned Ryobi #2 and thought I would upgrade to a :



HAFCO 13" THICKNESSER w/ HELICAL CUTTER HEAD

Now I was informed in the shop that with hardwood I should make a maximum pass depth of .05mm. It seemed small but I also didn't want to damage my new machine so I abided to the recommendation.

So first use of the machine it seemed great, a lot quieter and seemed like it was cutting with ease but now after a few hours of use on the same boards I have the same issue again, the rollers don't seem to be engaging and pulling the work through. I have tried gently aiding it through which works at times but the manufacturers specs specifically make mention against that practise. I have also tried going a bit deeper than the recommended .05mm to try and get the rollers engaged but the end result is a board moving through at a snails pace (if any) and being covered in faint roller skid marks.

Now I am a novice and this is the most use I have had with a thicknesser at any one point. So it seems I am left with two conclusions, I am doing something incorrectly or the timber is too hard/dense for the machine ?



I should make note that the machine is recessed into a bench so it has infeed and an out feed table yet to be fitted with rollers.



I apologise for the essay, I just wanted to try and make a detailed description to help aid diagnosis.



Any wisdom is greatly welcomed !



Thank you in advance :)
