Planner knife setting jigs

Postby Tom1989 » Fri Mar 14, 2014 12:35 pm

Hi Everyone,

The time has come to replace my planner/thicknesser blades (kity 439) and I'm absolutely dreading it! I usually spend hours with my verities straight edge trying to get the blades flush with the out feed table. The issue I encounter is that the blades are being pushed out by springs, which makes trying to get each end of the knife level an absolute nightmare. Is there some sort of jig that I can use that actually works. I looked at the Axminster jig but it has bad reviews. Any advice wood be much appreciated.

Many Thanks

Im sure Kity used to sell a planer knife setting jig which was very easy to use, it sat on the outfeed bed with markers for edge of the bed and then the knife would push up to the other mark.

I had one years ago but it went with the planer thicknesser. If i remember right there was a member on here a few months ago asking what was the attachment in the image, it was a Kity planer knife setting jig and went on ebay.

Are those the same as these? Looks very similar, and quite a bit cheaper.

I assume that you're referring to reviews on the Rutlands site. I bet if you spend all weekend looking, you won't find a single bad review for any of their equipment.

Now it's either all brilliant or, perhaps, they don't post the bad reviews.
Cheers,

Neil

Is the planer setting jig on Axminster the exact same as the one sold by record power? According to the review on Axminster, the build quality is rubbish. I will try and source the original jig for Kity if all else fails.

I used to use a dial gauge & magnetic base, works well & is very accurate.

I bought all the stuff for that, used it a few times and reverted to the bit of stick method as it is so much less fuss than making sure you have got the measurement of TDC etc. I then measured the effect of stick method using said expensive Mitutoyo digital etc set-up and (on a not very scientific test) it seemed amazingly precise and repeatably so.

I think I can hear the ghost of Grim jeering at me for spending out on stuff which is not made of stick.

+1
with two pencil lines at 1/8" apart. Place stick with first line on edge of in-feed table rotate block till second line drops on infeed-feed table (same spot as first line). Adjust until both sides match. Benefit = £30+ in your pocket rather than a retailer.

I just marked the table, then each time I set the knives I only had to clamp a straight edge to the mark, run the magnetic base against the straight edge & I had TDC straight away so not that much of a fuss.
My main reason for the dial gauge though was my thicknesser block was about 5 thou out from side to side when referenced against the bed, the easiest thing was to adjust the knives to make up this discrepancy.

As for Grim, he's busy spending money on equipment to burn sticks :lol:

+1 if theres any left from stirring stuff :lol:

The difficulty for the original poster is that the blades are spring loaded on Kity, the Kity jig uses the the same method as the stick but keeps the blades down with its weight. A homemade jig or heavy stick would do the same job.

A slight aside, but I have a warning and a recommendation for Hammer/Felder users.

First the warning. There are some cheap(er) planer blades available from Woodford Woodworking that have been advertised in some of the mags. Don't waste your money. The location holes on the ones I got were slightly too small and not consistently or accurately placed on the centreline. The blades finished up with some of them cutting too deeply and others not cutting at all (i.e. below the level of the outfeed table), and some cutting on one side and not the other.

The recommendation. I've just had my machines serviced by Felder for the first time (in 10 years :oops:), and the finish I'm now getting from the P/T is unrecognisable from what I was getting before (even with new genuine blades).

Those magnetic blade setters can't be used on the Kity 439, you can't get the beds far enough apart for them to sit on the block, I don't use any fancy jigs of bits of stick, just a piece of glass and set the blades level with the outfeed table, no snip just good clean cuts.
